Micro USB to USB-C Adapter
Keeping an existing cable can be convenient, but the wrong adapter may fit but not work. The BC-DAD009 range includes two separate Micro-B/USB-C adapter configurations. Choose based on the plug that enters the device and the socket that receives the cable, not the order of words in the product name.
Compare the Two Connector Arrangements
| Item | BC-DAD009-MC | BC-DAD009-CM |
|---|---|---|
| Male connector | Five-pin Micro-B | USB-C |
| Female connector | USB-C | Five-pin Micro-B |
| Physical arrangement | Micro-B plug enters a matching socket; USB-C socket accepts a USB-C plug | USB-C plug enters a matching socket; Micro-B socket accepts a Micro-B cable plug |
| Important selection limit | USB-C receptacle-to-legacy adapters are not a permitted standard Type-C adapter configuration. Do not specify this model as a universal standards-compliant adapter. | Review the legacy host/source, cable, and receiving USB-C device; the connector arrangement alone does not prove product compliance or compatibility. |

A Standards Limitation That Matters
The USB Type-C Cable and Connector Specification excludes USB-C receptacle-to-legacy adapter arrangements because they can enable invalid cable combinations. The MC configuration must not be treated as a general replacement for a standard cable, and a successful connection to one device does not establish standards compliance.
For a USB-C host connecting directly to a Micro-B peripheral, start with a USB-C to Micro-B cable. For a legacy USB-A host and a Micro-B peripheral, use a USB-A-to-Micro-B cable. These routes also avoid adding an extra rigid adapter at the equipment port.
Review the Complete Connection
For the CM model, you typically need to keep a USB-A-to-Micro-B cable when the receiving device switches to USB-C. Confirm source behavior, adapter wiring, and the receiving device rather than assuming every USB-C product accepts the same legacy connection. This is not an OTG accessory for connecting a storage drive to a phone.
Send the host or power-source model, device model, existing cable ends, and required data or charging task. We can then review the requested adapter against your setup and suggest a direct cable where appropriate.
Compare MC and CM Adapter Models
These are two separate models, not a reversible two-in-one adapter. Match the required male plug and female socket, then review the entire cable-and-device combination. If standards-compliant interoperability is a project requirement, use a suitable direct cable rather than the MC receptacle-to-legacy arrangement.

This model pairs a Micro-B male plug with a USB-C female socket. The arrangement is not a permitted standard USB Type-C legacy adapter configuration. For general USB-C host-to-Micro-B device connections, choose a suitable direct cable instead of assuming universal adapter compatibility.
P/N: BC-DAD009-MC

This model places a USB-C male plug on one side and a five-pin Micro-B female socket on the other. Review it when retaining a compatible legacy charging or data cable, and check the source, device roles, and power requirements before ordering.

Check Clearance Around the Device Port
Compact housing can work in a service kit, but it also adds a rigid connection at the device port. Leave room for both the adapter and the cable plug, and avoid letting the attached cable pull sideways on the socket.
Select the exact MC or CM configuration before discussing packaging or branding. For repeated field use, a direct cable may offer a simpler connection with fewer parts to misplace. A lanyard helps keep an adapter nearby; it does not lock the electrical connection.

MC has a Micro-B male plug and a USB-C female socket; CM has a USB-C male plug and a Micro-B female socket. They are separate models, not one reversible adapter. The MC arrangement also has the USB Type-C standards limitation explained above.
Do not assume fast charging from the connector shape or metal housing. The source, cable, adapter wiring, and device must support the intended charging behavior. No universal 2.4A or USB-C PD capability is specified here.
This family offers no OTG host function. Do not select these adapters to add host capability to a phone or tablet for a keyboard, drive, or controller. Choose a suitable OTG solution after confirming the device supports that role.
The listed interface capability is up to 480Mbps USB 2.0 signaling. This is not a guaranteed file-transfer rate. The host, peripheral, cable, and software determine actual performance, and every element of the route must carry data.
A compatible higher-speed device may support a USB 2.0 connection, but you must check the intended route. These adapters do not add USB 3.x, Thunderbolt, or native video capability. The plug must also physically match the port.
The series includes an aluminum-alloy housing and a lanyard attachment. Confirm the selected finish, marking, and supplied accessory. Housing material alone does not determine electrical performance, ruggedness, or a specific durability-test rating.
The MC model has a USB-C socket, but standard Type-C adapter arrangements exclude USB-C receptacle-to-legacy adapters. For a USB-C host and Micro-B peripheral, use an appropriate direct cable rather than treating this adapter as universally compatible.
The adapter itself does not require driver installation. The connected device may still require drivers, applications, or supported USB roles. Driver-free hardware does not mean that any two devices will communicate when their plugs fit.
No fixed service life or 10,000-cycle guarantee is established here. If repeated mating is important, specify the required acceptance test and request evidence for the exact model. Handle the housing, not the attached cable.
Send your logo or marking requirements, packaging format, chosen model, and quantity for review. Confirm the approved sample and order specifications before production; branding does not change the selected adapter’s connection limits.
Consider a direct cable when the adapter protrudes too far, strains a recessed port, or creates an unsuitable connection arrangement. Send the source and device ports, route length, and required function so we can select a suitable cable instead.
Before Adding an Adapter to Your Service Kit
A small adapter looks like an easy way to keep existing cables in use. That can help with a controlled equipment setup, but it is a poor substitute for understanding what the connection actually needs to do. Start a purchasing decision with the complete route from source to device.
Describe Both Ends, Not Just the Adapter Name
Write down the connector on the source, both ends of the existing cable, the adapter plug and socket, and the receiving device port. Add the exact equipment models. This simple record prevents ordering the wrong connector arrangement and shows whether a direct cable would be a better fit.
Use the actual MC or CM part number in the quotation and sample approval. Labels such as Model A, Model B, or two-way adapter are easy to misinterpret when several suppliers use different naming conventions.
Keep Data Roles Separate from Connector Gender
A male plug isn’t necessarily a host, and a female socket isn’t necessarily a peripheral. The equipment and the connection wiring determine those roles. These adapters do not add OTG host capability, and fitting one to a phone does not turn that phone into a host for a keyboard or drive.
For data use, identify the host and the supported peripheral function. The operating system may still need a device driver or application, even though the adapter itself doesn’t install software. A charging-only cable elsewhere in the route will not carry data.
Choose a Direct Cable Where Practical
One correctly specified cable avoids an additional mating interface and reduces the amount of rigid hardware protruding from a port. This is especially useful around recessed sockets, protective cases, and equipment moved during operation. Check the route before choosing an adapter, and reuse a cable you already have.
The MC model carries a standards limitation described above. Do not use it to create an arbitrary chain of adapters or assume that sample operation makes that arrangement standards-compliant. For broad interoperability, request the appropriate cable assembly instead.
Check the Power Source Independently
The adapter is not a charger or a voltage converter. A metal housing and a USB-C connector do not establish a fast-charge protocol, safe current rating, or USB Power Delivery support. Evaluate the source, complete cable route, and receiving device together, and agree on electrical limits before ordering for a charging application.
Make a Sample Evaluation Useful
Use the actual source, cable, and device intended for deployment. Check mechanical clearance, reliable device detection, the required data task, and the intended charging behavior. Include both orientations of the USB-C connection where applicable. Record the approved combination so a later cable substitution does not quietly change the installation.
For repeated plugging, transport, or demanding environments, specify acceptance criteria and request applicable evidence. Do not assume a cycle-life, temperature, or drop-test rating from the housing material alone.
Send a Clear Inquiry
Include the part number, connection diagram or photos, source and device models, required function, quantity, labeling, and packaging. State any compliance documentation or traceability requirements at the quotation stage. Send your connection details for review, or compare other Micro USB cable options when an adapter is not the right route.
