ZH series, Board to Cable/Wire, 4 Positions, Header, 0.059\" (1.50mm) Pitch, Through Hole, Solder, Tin, Shrouded - 4 Wall, Detent Lock, 1A, 50V","salesMarkdown":"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.","metaTitle":"B4B-ZR(LF)(SN) JST ZH 4-Pin Header, 1.5mm Pitch","metaDescription":"JST ZH series 4-position shrouded header, 1.50mm pitch, 1A/50V rating, tin-plated contacts.
