Product details

It mates with EH series crimp housings to form a locked, vibration-resistant joint.

Contact length on the mating side is 0.130" (3.30 mm), and the post length is 0.126" (3.20 mm) — enough to clear a standard 1.6 mm board and still have solder tail for a reliable joint. Compared to the 6-position B6B-EH-A, this 5-position version saves one board hole and one wire crimp — the rest of the footprint and electrical ratings are identical.

Sourced per RFQ — confirm the BOM quantity and we'll quote against current market pricing and availability.

Locking and termination details

Termination is press-fit, solder — the pins press into the plated through-hole and get wave or hand soldered. The square pin shape gives four contact points in the hole for a consistent solder fillet.

Frequently asked questions

What is the pitch of B5B-EH-A?

The pitch is 0.098" (2.50 mm) between centers, matching the standard JST EH series footprint.

Is B5B-EH-A compatible with JST EH series?

Yes, it is part of the EH series and mates with EH series crimp housings and terminals. The friction lock aligns with the housing latch.

What is the closest second-source to B5B-EH-A?

The closest functional equivalent is B5B-EH-A(LF)(SN) — same pin count, pitch, current, voltage, and locking feature. The (LF)(SN) suffix indicates lead-free and tin-plated variations; check your soldering process requirements.
