13-position shrouded header with locking ramp
The 1-1971922-3 is a single-row, 13-position header from TE Connectivity's 2.50mm pitch line, with only 7 positions loaded — the remaining 6 are empty cavities. That loaded count is the number that connects; the unloaded positions are placeholders for future expansion or keying. A full 4-wall shroud surrounds the mating interface, protecting the tab contacts from stubbing and misalignment during blind mating — common in panel-to-board harness drops.
Glow wire and flammability for appliance duty
Glow wire compliant and rated UL94 V-0, the polyamide housing is suited for household appliances, lighting fixtures, and HVAC controls.
Supplied in tube packaging (standard for through-hole headers to prevent pin damage during handling and machine feeding). ROHS3 compliant, with no exemptions listed — suitable for EU and California market equipment.
Fit comparison with 1-2232960-3
For a 7-circuit loaded requirement, the 1-1971922-3 is the correct part — the 1-2232960-3 cannot be substituted because its position count is lower.
