36-position 2.50mm pitch header for board-to-wire power distribution
The 3-1969584-6: This is a 36-position, dual-row, vertical through-hole header from TE's Economy Power 2.5 series. The kinked solder tails provide through-hole retention during wave solder — no secondary board lock needed for most applications.
Glow wire and flammability compliance for lighting and industrial
Glow wire compliant per IEC 60335-1 — a requirement for household appliances and lighting fixtures where the connector must not ignite under a hot-wire fault. The housing material carries UL94 V-0, the highest flammability rating for nylon, meaning it self-extinguishes within 10 seconds of flame removal.
Where this fits in the Economy Power 2.5 line
The Economy Power 2.5 series covers 2 to 36 circuits in single and dual rows. This 36-position variant is the maximum circuit count in the series — the full pin density for a board-to-wire interconnect that needs 36 signal or power lines in a compact footprint. Compared to the 12-position 1379030-3 (2.54mm pitch, right-angle, board lock) or the 11-position 1-292164-1 (2.00mm pitch, single row, detent lock), this header offers 2.50mm pitch, dual rows, and a friction lock — a middle ground between fine-pitch signal headers and wider-pitch power connectors.
