20-Position SMT Header with 1.27mm Pitch and 6.42mm Stack Height
The 1.27mm pitch sets a compact board footprint, while the 6.42mm mated stack height defines the z-height budget for mezzanine board spacing — a mismatch here breaks the assembly. Rated at 1 A DC per contact, the current ceiling is limited by the narrow pitch and the thermoplastic housing's thermal capacity.
Sourcing and Availability — Active Production, Tape & Reel
It is RoHS compliant. The part includes a pick-and-place feature and board guide for alignment during reflow.
Tube vs Tape & Reel — 87409-110LF as a Drop-In Alternate
The sibling 87409-110LF is identical in every spec — same 20 positions, 1.27mm pitch, 6.42mm stack height, gold mating finish — but packaged in a tube instead of tape & reel. For hand-assembly or low-volume builds, the tube version is a direct drop-in without a footprint change. If you need more circuits, the 30-position 87409-115LF shares the same pitch, stack height, and plating grade — a straightforward BOM adjustment without requalifying the board layout.
