The 1.50 mm pitch demands a correspondingly tight footprint — verify pad layout against the JST product drawing before committing the board.
The pitch is 0.059" (1.50 mm). This is the center-to-center spacing between adjacent pins.
No, the B4B-ZR-SM4-TF is listed as RoHS non-compliant. If you need a RoHS-compliant version, consider the alternate part B4B-ZR-SM4-TFT(LF)(SN) which is noted as having a different finish.
This header mates with JST ZH series crimp receptacles. The mating housing is a ZH-series female connector (e.g., ZHR-4 or similar) using the appropriate crimp terminals (e.g., SZH-002T-P0.5). Confirm the exact housing and terminal part numbers from the JST ZH series catalog.
