30-Position Dual-Row Receptacle at 0.100" Pitch
The 66953-015LF: The push-pull fastening type and square female socket contacts accept square or round header pins of the same pitch. Black glass-filled polyester housing rated UL94 V-0, operating from -65°C to 125°C, with a voltage rating of 1250 V.
Where It Fits on the Board and in the System
With a 0.325" (8.25 mm) insulation height and 0.138" (3.50 mm) post length, this receptacle sits low enough for dense board stacks but leaves clearance for routing under the body. Applications listed include automotive, general purpose, industrial, medical, and telecommunications — the wide temperature range and flame-rated housing support equipment inside enclosures requiring UL94 V-0 compliance.
Comparing 30 vs 32 Positions: 66953-015LF and 66953-016LF
The 32-position sibling 66953-016LF shares every other spec — same pitch, row spacing, gold thickness, tail length, housing material, temperature range, and voltage rating. If your BOM calls for 32 positions, the 016LF drops in without a footprint change.
