Product details

The B5B-ZR-SM4-TF is a 5-position, single-row SMT header from JST's ZH series, pitched at 1.50 mm. It's a shrouded 4-wall header, which means the receptacle self-aligns during mating and the pins stay protected from accidental bending — a real help when you're assembling a harness blind in a tight enclosure.

At this pitch and contact size, the 1 A limit is driven by the temperature rise of the PA6T housing — push past it and the plastic creeps, losing contact force. The 50 V rating is conservative for signal-level work; it's the clearance between adjacent pins that sets the ceiling, not the insulation.

Frequently asked questions

What is the pin pitch of B5B-ZR-SM4-TF?

The mating pitch is 0.059 inches (1.50 mm). That's the center-to-center spacing of the pins.

Is B5B-ZR-SM4-TF surface mount?

Yes, it's a surface-mount header. The termination is solder, and the part includes solder retention features to hold it in place during reflow.

What is the current rating of B5B-ZR-SM4-TF?

Rated 1 A per contact at 50 V. The current limit is set by the temperature rise of the PA6T housing material.

Is B5B-ZR-SM4-TF compatible with ZH series connectors?

Yes, it's part of the ZH series. It mates with ZH-series crimp receptacles (e.g., ZHR-5) using the appropriate crimp terminals. The detent lock provides audible feedback when fully mated.
