If your harness needs all 7 circuits, this part won't carry the signal on those three pins; you need a fully loaded version or a different order code. ROHS3 Compliant — no RoHS exemption issues for EU-market builds. ## Comparing to the Fully Loaded Sibling (1-2232960-3) The closest functional alternative is 1-2232960-3 — same 2.50 mm pitch, same shrouded 4-wall design, same locking ramp and UL94 V-0 material. The difference: 1-2232960-3 has 3 positions, all loaded, and ships in a box instead of bulk. If you need all 7 circuits populated, neither this part nor 1-2232960-3 covers it — you'd need a different order code in the 1971921 base series. ## Temperature Range and Application Fit The UL94 V-0 nylon housing won't sustain flame inside an enclosure.","metaTitle":"1-1971921-7 TE Connectivity Header 7 Pos 2.5mm Pitch 4","metaDescription":"1-1971921-7 TE Connectivity AMP Connectors pin header, 7 positions, 2.50 mm pitch, 4 positions loaded, shrouded, locking ramp, UL94 V-0.
