What the 79821-132HLF is
The Amphenol FCI 79821-132HLF is a 32-position dual-row unshrouded header in the BERGSTIK II series, rated 5 A per circuit at 0.100 inch (2.54 mm) pitch. Square pins on 0.100 inch row spacing terminate via through-hole solder and carry gold-plated contact faces rated 30.0 µin (0.76 µm) gold or Gold GXT on the mating side. The push-pull fastening holds the mating connector without a latch screw — suited for board-to-board stacking in instrumentation and industrial control where the board population is dense and a locking螺钉 is impractical.
What the ratings mean for your board
32 positions across two rows at 0.100 inch pitch — confirm your board edge clearance and routing channel before committing. Each circuit carries 5 A and the 110 V dielectric rating sets the pin-to-pin voltage limit.
Where it goes and how it mates
Board-to-board stacking header — the square pin geometry and 0.430 inch (10.92 mm) engagement length mates with a matching 0.100 inch pitch BERGSTIK II female IDC or receptacle. The 0.200 inch (5.08 mm) tail length suits standard through-hole pad footprints; the 0.100 inch (2.54 mm) insulation height sets the installed stack separation. All 32 positions are loaded, so confirm your board routing avoids split-plane interruptions beneath the connector body. The phosphor bronze contact material and push-pull fastening type mean the male pin array carries the full insertion force at mate — the receptacle housing must have compliant beam contacts rated to accept that insertion without contact deformation over the expected cycle count.
Sourcing and the BOM check
Listed Active with no official successor or cross-reference for the 79821 base product number. The 32-position member sits at the high end of the BERGSTIK II dual-row range; if your board population requires fewer circuits, a lower-position variant in the same series would be the natural BOM revision.
