The SM24B-ZPDSS-TF is a 24-position, dual-row header from JST's ZPD series, pitched at 1.50 mm and terminated by SMD soldering in a right-angle orientation. The 2 A per-contact current rating and 100 V voltage ceiling place it firmly in the signal-level interconnect class — think control boards, sensor interfaces, and internal wiring in appliances or industrial equipment where 1.50 mm pitch saves board real estate. The four-wall shroud and locking ramp mean the mated pair resists vibration-induced separation — a practical advantage in moving assemblies or field-serviceable enclosures.
Pitch, positions, and board-fit check
At 1.50 mm pitch and 24 positions across two rows, the header occupies a 12-contact-per-row footprint.
Sourcing and compliance reality
Critical flag: this header is RoHS non-compliant. If your BOM mandates RoHS, you'll need an exemption or an alternate part. No direct RoHS-compliant equivalent is listed in the ZPD series for this exact position count.
