Product details

34-position 2.00mm pitch vertical header for wire-to-board builds

The B34B-PHDSS is a 34-position, 2-row, 2.00mm pitch vertical header from JST's PHD series, designed for board-to-cable/wire applications.

Footprint and stack height for board layout

Mated stacking height is 8.8 mm, with a 0.114" (2.90 mm) mating pin length and a 0.118" (3.00 mm) solder tail. Compared to the 32-position sibling B32B-PHDSS, this part adds two circuits in the same row spacing (2.00 mm) and identical 8.8 mm stack height, making it a drop-in footprint upgrade for designs needing more I/O.

Sourcing and compliance note

Frequently asked questions

What is the mating connector for B34B-PHDSS?

The mating half is a PHD series crimp-style receptacle housing (e.g., PHR-34 or similar) that accepts the appropriate crimp terminals. The header and receptacle together form the board-to-cable/wire connection.

Is B34B-PHDSS RoHS compliant?

No — the listing shows RoHS non-compliant. If your project requires RoHS compliance, consider the alternate MPN B34B-PHDSS(LF)(SN) which carries the same mechanical footprint and ratings.
