Board footprint and mating interface
The 1-2232511-3: 3 positions, with only 2 loaded from the factory — the third cavity is present but unpopulated, which matters when the mating half expects a full complement of terminals.
Glow wire and flammability for appliance duty
Glow wire compliant per IEC 60335-1 — the PA66 housing and UL94 V-0 rating mean this header can be used in appliances and industrial controls where a glowing element test is required for safety certification. Silver plating on both the mating tab and the solder post — silver carries the current with low contact resistance but tarnishes in sulphurous atmospheres; for clean indoor equipment the trade-off is acceptable.
Sourcing and lifecycle posture
ROHS3 Compliant. Bulk package — the header ships in tubes or trays, not tape-and-reel, so plan for hand or tube-fed insertion.
The 5.00 mm pitch of 1-2232511-3 gives more room for routing traces between pads and a higher voltage rating (250 VAC vs 50 VAC).
