Custom 50 Pin SCSI Cable Assemblies
A 50-pin SCSI cable is commonly associated with narrow SCSI equipment, but the contact count alone is not enough to specify a replacement. Two assemblies can both be described as “50-pin SCSI” while using different connector families, genders, retention systems, cable constructions, or pin assignments.
Our custom cable process begins with the actual mating interfaces. You can provide an equipment manual, connector part number, front-view port photos, an approved wiring diagram, or an existing cable sample. We then use the agreed specification to define the connector orientation, pin mapping, finished length, retention hardware, labeling, and other production requirements.
This page covers custom HPDB50, Centronics 50, and equipment-specific 50-position assemblies. For a broader view of available interfaces, visit our SCSI cable collection.
Do not order a new cable based solely on the phrases “50 pin” or “SCSI-2.” Before production, confirm the physical connector and the electrical requirements of the installed equipment.

BespokeCable manufactures custom 50-pin SCSI cable assemblies for legacy storage equipment, industrial systems, and replacement projects. Available configurations can include HPDB50, Centronics 50, internal 50-position connectors, and equipment-specific transitions.
Because “50-pin SCSI” does not identify the connector style, gender, pin map, or signaling mode, specify each assembly against your mating equipment, drawing, or approved sample. You can define the connector combination, cable length, retention hardware, exit direction, shielding, labels, and packaging required for your installation.
Send us clear port photos, equipment model numbers, a pin-to-pin drawing, or an existing cable sample for technical review.
HPDB50 SCSI Cable Assemblies
HPDB50 assemblies are built for equipment with a confirmed half-pitch 50-position interface. Before production, identify the gender at each end, screw or clip hardware, connector orientation, cable length, and pin map. An HPDB50 assembly can use the same connector family at both ends or transition to a Centronics 50 or equipment-specific interface when supported by the approved wiring diagram.
P/N: BC-CSC004-HPDB50-PS
A molded-hood HPDB50 assembly for installations that require screw retention. Confirm the mating connector, gender, screw hardware, cable length, and pin map against your equipment or approved drawing.
P/N: BC-CSC004-HPDB50-MS
A metal hood HPDB50 assembly for equipment that requires screw retention and a defined shell connection. Specify the hood clearance, shell bonding, cable exit, and wiring requirements in the approved production drawing.
P/N: BC-CSC004-HPDB50-MC
A metal-hood HPDB50 assembly for mating hardware that uses snap-on retention. Provide clear port photographs or the connector part number so the latch style and available installation space can be checked.
Centronics 50 SCSI Cable Assemblies
Centronics 50 assemblies use a larger rectangular connector and must match the equipment’s contact count, gender, retention system, and pin map. “Centronics” describes the connector form; it does not independently confirm the protocol. For cross-family projects, we can manufacture an HPDB50-to-Centronics 50 cable only after both interfaces and the pin-to-pin wiring have been approved. See our Centronics SCSI cable assemblies for additional connector-format options.
P/N: BC-CSC004-CN50
A Centronics 50 assembly for equipment with a confirmed CN50 interface. Specify the connector gender, bail-clip or screw retention, finished length, pin map, and backshell clearance before approval.
Typical Applications
- Legacy storage enclosures
- Tape drives and tape libraries
- Older scanners and imaging equipment
- Industrial computers
- Test and measurement systems
- Semiconductor or production equipment
- Equipment repair and refurbishment
- Replacement of discontinued cable assemblies
- OEM systems with proprietary 50-position pinouts
Application names do not prove compatibility. Confirm the exact connector, pin assignment, signaling mode, and equipment documentation before approving production.
What to Send for a 50 Pin SCSI Cable Quotation
- Host and peripheral equipment manufacturer and model
- Clear front-view photos of both ports
- Connector family, contact count, and gender
- Retention hardware and hood clearance
- Required finished length and installation type
- Pin-to-pin drawing or original cable sample
- Confirmed signaling information
- Label, packaging, documentation, and inspection requirements
- Sample quantity and estimated production quantity
If you only have an existing cable, send full-length photographs and close-ups of both connector faces. We can use this information for preliminary identification and advise what additional data is required before production approval.
Controlled Production for Repeat Orders
Assign a customer part number and drawing revision to the approved assembly. Each repeat purchase should reference the same controlled information. Connector substitutions, cable changes, or pin-map revisions should require written approval before production.
The production package can define connector part numbers, cable construction, finished length and tolerance, pin mapping, orientation, retention hardware, labels, workmanship requirements, and acceptance criteria. Review our quality control process when preparing your project requirements.
Yes. You can submit multiple drawings or BOM lines in the same inquiry. Assign a separate part number and revision to each connector combination, pin map, or cable length to keep configurations controlled during sampling and repeat purchasing.
An original sample can support connector identification, dimensional review, and continuity mapping. Still confirm the final production specification against equipment documentation or an approved drawing, especially if the sample is damaged, repaired, or electrically uncertain.
You may include customer part numbers, revision information, barcodes, QR codes, and other agreed-upon identification in the quotation. Provide the label content, format, location, and scan requirements with your drawing or packaging specification.
Include your sample requirements and expected production quantity in the inquiry. The available pilot arrangement depends on connector availability, tooling, documentation, and the selected cable construction, and we will address it in the quotation.
List any approved manufacturer, mandatory part number, or prohibited substitution in the purchasing specification. Where repeated construction must remain unchanged, the controlled BOM and drawing revision should be referenced on each order.
Provide the product part number, drawing revision, order or lot reference, quantity affected, photographs, and a clear description of the issue. For an electrical issue, include the measured pin locations, test method, and equipment condition, where possible.
Project-specific packaging can be discussed during quotation. Specify the quantity per bag or carton, label information, kit grouping, spare-part identification, and any storage instructions required by your distribution or maintenance process.
How to Specify a 50 Pin SCSI Cable for Replacement or OEM Production
Ordering a 50-pin SCSI cable by contact count alone risks receiving an assembly with the wrong connector, gender, retention system, or pin map. A controlled specification should identify both mechanical and electrical requirements before production.
Start With the Mating Connector
Determine whether the equipment uses HPDB50, Centronics 50, IDC, or another 50-position interface. Provide front-view photographs showing the connector face, retaining hardware, and available clearance. If you have a connector part number, include it with the inquiry.
Confirm Gender and Retention
Connector gender can be described inconsistently depending on the viewing side. Mark the host end and device end separately and confirm screws, clips, latches, or other retention hardware from the mating interface.
Define the Pin Map and Viewing Direction
A straight-through connection should not be assumed. The approved pin map should state whether each view is from the connector mating face or cable-entry side. This prevents mirrored numbering and reversed wiring. Document shields, shell bonds, drain connections, jumpers, unused contacts, and any equipment-specific circuits.
Confirm the Signaling Requirement Separately
A 50-position connector does not independently prove whether the equipment uses SE, HVD, LVD, or a proprietary interface. Provide the host and peripheral model numbers and any applicable equipment documentation. Establish compatibility from documented system requirements rather than connector appearance.
Specify the Mechanical Installation
For external assemblies, confirm finished length, hood dimensions, retention hardware, cable exit, bend space, flexing, abrasion, and nearby noise sources. For internal assemblies, also document the number and spacing of connectors, pin-1 orientation, host and device order, and any terminator position.
Use an Approved Drawing or Golden Sample
The production reference should identify connector part numbers, gender, orientation, pin mapping, shield connections, cable construction, length and tolerance, retention hardware, labels, test criteria, and revision. If an existing cable is supplied, agree whether it is a dimensional reference, wiring reference, or complete golden sample.
Define Acceptance Criteria Before Production
Continuity testing can verify intended connections and unwanted shorts, but it does not prove every signal-integrity or system-performance requirement. Define any additional electrical or mechanical test method, limit, and sampling requirement before quotation.
Control Reorders by Part Number and Revision
Reference the approved customer part number, drawing revision, and any golden-sample identifier on repeat orders. This turns an obsolete or proprietary cable into a controlled purchasing item instead of a repeated reverse-engineering exercise.
