Product details

SMT header for ZH wire-to-board

The B3B-ZR-SM4-TF is a 3-position, single-row male pin header from JST's ZH series. It uses a 1.50 mm pitch and surface-mount termination, with a shrouded 4-wall design that protects the pins and guides the mating female housing into alignment.

Rated for signal-level current

Board-fit and stack height

The natural (off-white) color is standard for the ZH series.

SMT vs through-hole: same pitch, different stack

The through-hole sibling B3B-ZR has the same 1.50 mm pitch, 3 positions, and 1 A rating, but its mated stack height is 5.6 mm versus 6.4 mm for the SMT version. The through-hole part also lacks the solder retention feature. If your board assembly is wave-solder only, the through-hole version is the direct fit; for reflow, the SM4-TF is the correct choice.

Frequently asked questions

What is the pinout of B3B-ZR-SM4-TF?

It is a single-row, 3-position header with all positions loaded. Pin 1 is typically marked by a chamfer or dot on the housing. The mating female housing (ZH series crimp housing) accepts the corresponding crimp terminals; the pinout follows the standard 1-to-1 mapping.

Is B3B-ZR-SM4-TF RoHS compliant?

No, the B3B-ZR-SM4-TF is listed as RoHS non-compliant. For RoHS-required applications, use the lead-free variant B3B-ZR-SM4-TF(LF)(SN).
