It carries a 5.00 mm pitch, which gives generous creepage for the 250 VAC rating without forcing an oversized footprint — a practical balance for a 20 A power line. The silver-plated tab contacts handle 20 A per circuit, meaning each position is sized for a main DC rail or a power distribution node, not a signal line. ## Construction and key features The header is shrouded on all four sides (4-wall) with a latch holder for positive retention against the mating receptacle — the lock engages audibly and resists vibration in a harness assembly. A board guide assists alignment during hand-assembly or automated insertion. The through-hole solder termination with a 0.138\" (3.50 mm) post length suits standard PCB thicknesses. The natural polyamide (nylon) housing carries a UL94 V-0 flame rating, so it's accepted inside equipment enclosures that require flame retardance. The operating range spans -40°C to 120°C, covering automotive underhood and industrial cabinet environments. ## Contact plating and compliance Both the mating surface and the solder post carry silver plating — silver gives lower contact resistance than tin for power applications, though it tarnishes in corrosive atmospheres faster than gold. For a clean, dry indoor power supply or appliance environment, silver is a cost-effective choice. The connector is ROHS3 Compliant per the manufacturer listing, and the glow wire compliant feature (per) supports IEC/EN 60335-1 appliance safety requirements. The 2-1971896-4 carries an Active lifecycle status from TE Connectivity — full production, no end-of-life notice on record.","metaTitle":"TE Connectivity 2-1971896-4 Header, 4 Pos, 5mm Pitch, 20A","metaDescription":"TE Connectivity 2-1971896-4 vertical header, 4 positions, 5.00 mm pitch, rated 20 A, 250 VAC.
