Product details

The 1.50 mm pitch and detent lock are consistent across the ZH series — any 4-position ZH receptacle will mate with this header.

No end-of-life notice or successor has been issued — it remains a current production item suitable for new designs.

Peer Comparison — Through-Hole vs Surface-Mount Variants

The closest functional alternative is the base part B4B-ZR, which is identical in pitch, position count, current rating, and shrouding. The (LF)(SN) suffix on this part indicates lead-free and tin-plated contacts — the same as the base B4B-ZR. If the board assembly process prefers surface mount, the B4B-ZR-SM4-TF and B4B-ZR-SM4-TFT(LF)(SN) variants offer the same 4-position ZH header with solder retention features and a slightly taller mated stack height of 6.4 mm.

Frequently asked questions

What is the mating connector for B4B-ZR(LF)(SN)?

The mating half is a JST ZH series 4-position crimp receptacle housing, such as ZHR-4, loaded with SZH-002T-P0.5 terminals.

Is B4B-ZR(LF)(SN) shrouded?

Yes, it is a shrouded header with full 4-wall protection. The shroud guides the mating receptacle and reduces the risk of bent pins during handling or assembly.
