Two positions at 6.35 mm pitch — the footprint is the story
The 1586953-1: This is a 2-position, single-row header with a 0.250-inch (6.35 mm) pitch, so the board footprint is two holes spaced 6.35 mm apart. The 0.155-inch (3.94 mm) solder tail length suits standard through-hole assembly on a 1.6 mm board. Rated 12 A per contact at 600 VAC, with tin-plated phosphor bronze contacts.
Glow wire and locking ramp — safety and vibration resistance
Glow wire compliant per IEC 60695-2-11, which makes this header suitable for appliances and equipment where a glowing hot element must not propagate flame. The UL94 V-2 nylon housing adds a second layer of flammability protection.
Active production — no LTB risk
Active status on the TE line, ROHS3 compliant, no end-of-life notice on record.
