Product details

3.96 mm Pitch, 4-Position Wire-to-Board Header

Termination is solder through-hole — the 0.125 inch (3.18 mm) post length provides enough stand-off for wave-solder clearance on standard 1.6 mm PCBs.

The part is ROHS3 compliant, and the base product number 644615 covers the series variant.

Peer Alternatives in the MTA-156 Series

Compared to the 1-1871673-2 (also MTA-156, 4 positions, vertical), the 3-644615-4 shares the same pitch, row count, and friction lock — the difference is in contact finish thickness and packaging. The 953440-3 is a 3-position variant for lower circuit-count applications. The 1-292164-1 is a right-angle version, which changes the board-edge routing and z-height profile.

Frequently asked questions

What is the mating connector for 3-644615-4?

The 3-644615-4 mates with MTA-156 series receptacle housings that accept the corresponding crimp contacts. The friction lock engages with the mating half's locking ramp.

Is 3-644615-4 RoHS compliant?

Yes, the part is ROHS3 compliant per TE Connectivity's certification.
