Product details

MTA-100 IDC Receptacle for Discrete or Ribbon Cable

It uses a 0.100" (2.54mm) pitch, matching the standard MTA-100 header footprint.

Termination and Wire Handling

It works with 28 AWG wire, either discrete strands or ribbon cable. The feed-through feature means the cable can pass through the housing, which simplifies daisy-chain wiring in a harness.

Mating and Compatibility

The locking ramp engages the header latch for a secure mate; you will hear it click when fully seated. For a 4-position harness, the 3-640623-4 is the receptacle half; the matching header is any 4-position MTA-100 pin header, such as the 640445-4 series. The green housing color is a visual aid during assembly — helps spot the right position count on a crowded harness board.

Frequently asked questions

Is the 3-640623-4 compatible with standard MTA-100 headers?

Yes. The 0.100" (2.54mm) pitch and single-row layout are the MTA-100 series standard, so this receptacle mates with any 4-position MTA-100 pin header. The locking ramp provides a positive retention when mated.

Where can I buy the 3-640623-4?

This part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for your target quantity and lead time.

Does the 3-640623-4 have a locking ramp for secure mating?

Yes, the fastening type is a locking ramp. It engages the header latch and provides a vibration-resistant connection that resists accidental disconnection in service.

Can I use 28 AWG stranded wire with the 3-640623-4?

Yes, the connector is specified for 28 AWG wire, and the IDC termination works with both discrete and ribbon cable. Stranded 28 AWG is within the intended wire range for this MTA-100 receptacle.
