PAD series Board to Cable/Wire header, B20B-PADSS, 20 positions, 2 rows, 2.00mm pitch, through-hole, shrouded - 4 wall, locking ramp, tin contacts, UL94 V-0, 3A, 250V.","salesMarkdown":"## 20-position, 2.00mm pitch shrouded header for board-to-wire The B20B-PADSS is a JST PAD series male pin header with 20 positions arranged in two rows at 0.079\" (2.00mm) pitch, designed for board-to-cable/wire applications. The locking ramp fastening type secures the mating half against vibration — a practical feature for equipment that sees shock or movement in service. ## Current, voltage, and temperature limits for the board layout ## Housing material and flammability rating Note that this part is RoHS non-compliant, which may affect use in regions with RoHS restrictions or require an exemption declaration. ## How B20B-PADSS compares to the 22-position sibling The closest peer in the same PAD series is the B22B-PADSS, which offers 22 positions instead of 20, with identical pitch (2.00mm), stack height (12.4mm), current rating (3 A), voltage (250 V), and locking ramp. If your BOM needs two more circuits, the B22B-PADSS is a drop-in alternative with the same footprint and mating interface — just two extra pins in the same row layout.","metaTitle":"B20B-PADSS JST PAD Header 20 Pos 2mm TH Shrouded Locking","metaDescription":"B20B-PADSS JST PAD series header, 20 positions, 2 rows, 2.00mm pitch, through-hole, shrouded with locking ramp, 3A, 250V, UL94 V-0.
