Active 18-Position Header for Wire-to-Board
The B18B-PUDSS-1(LF)(SN) is an active-production JST PUD series header, 18 positions in two rows at 0.079" (2.00mm) pitch, rated 3 A per contact at 250 V. Through-hole solder termination, tin-plated mating surface, and a UL94 V-0 glass-filled nylon 6/6 housing. Operating temperature spans -25°C to 85°C.
18 vs 20 Positions: What Changes
Compared to the B20B-PUDSS-1 (20 positions), the B18B-PUDSS-1 shares the same 2.00mm pitch, 3 A rating, 250 V, latch holder, and 11mm mated stack height. The only parametric difference is the position count — 18 circuits vs 20 circuits — which changes the PCB footprint length and the mating housing part number. Both are active, tray-packed, natural color, tin-plated, and RoHS compliant. No other sibling in the PUD series (B22B-PUDSS-1, B24B-PUDSS-1) alters the electrical or mechanical ratings.
This header mates with JST PUD series crimp housings (sold separately).
