The shrouded 4-wall housing and detent lock provide a secure mate with the matching crimp receptacle, making it a compact signal interconnect for tight PCB layouts. The 5.6 mm mated stack height keeps the wire exit close to the board surface.
The 1.50 mm pitch demands a tight PCB footprint — the 0.106" (2.69 mm) post length and 0.094" (2.40 mm) mating pin length set the through-hole drill and solder fillet geometry.
The B3B-ZR mates with a JST ZH series crimp receptacle housing, such as the ZR-3 (3-position), loaded with the appropriate crimp terminals. The detent lock on the header engages with the receptacle latch for a positive hold.
The B3B-ZR is rated at 1 A per contact at 50 V.
No official replacement is listed. The B3B-ZR-SM4-TF is a surface-mount variant of the same 3-position, 1.50 mm pitch ZH header, but with a different mounting style and a 6.4 mm stack height. For a through-hole replacement, the B4B-ZR offers 4 positions in the same series.
