EH series, Board to Cable/Wire Header, 5 Positions, 2.50mm Pitch, Through Hole, Shrouded - 3 Wall, Friction Lock, Tin Contacts, 3A, 250V, UL94 V-0, Active","salesMarkdown":"It mates with EH series crimp housings to form a locked, vibration-resistant joint. Contact length on the mating side is 0.130\" (3.30 mm), and the post length is 0.126\" (3.20 mm) — enough to clear a standard 1.6 mm board and still have solder tail for a reliable joint. Compared to the 6-position B6B-EH-A, this 5-position version saves one board hole and one wire crimp — the rest of the footprint and electrical ratings are identical. Sourced per RFQ — confirm the BOM quantity and we'll quote against current market pricing and availability. ## Locking and termination details Termination is press-fit, solder — the pins press into the plated through-hole and get wave or hand soldered. The square pin shape gives four contact points in the hole for a consistent solder fillet.","metaTitle":"B5B-EH-A JST EH Header 5 Pos 2.5mm Pitch Through Hole","metaDescription":"JST B5B-EH-A EH series header, 5 positions, 2.50mm pitch, through hole, friction lock, 3A, 250V, UL94 V-0.
