Product details

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.

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.

Frequently asked questions

What is the mating connector for B20B-PADSS?

This header mates with a JST PAD series crimp receptacle housing (e.g., PADP-20V-1-S) using the appropriate crimp terminals. The 2.00mm pitch and locking ramp are specific to the PAD series — confirm the mating half part number against your wire harness.

Are there alternatives to B20B-PADSS?

Within the same PAD series, the B22B-PADSS (22 positions) is a direct alternative if you need two more circuits. Both share the same pitch, stack height, current rating, and locking ramp.
