0.100" Pitch, 10-Position Breakaway Header — What It Fits
3 A Signal-Duty Ceiling and Plating Trade-Offs
The base product number is 77313, and the full order code 77313-102-10LF is the production part number, not a sample or pre-release variant.
10 vs 14 Positions — When to Move Up
The closest functional sibling is 77313-102-14LF, which shares every spec except position count: same pitch, same 0.100" row spacing, same 0.230" mating pin length, same gold plating, same UL94 V-0 housing. The 14-position version gives you four extra signal lines on the same footprint length — useful if your board layout has spare I/O or if you're standardising on a single header for multiple harness variants. The 10-position version here is the right choice when the BOM calls for exactly 10 circuits and you don't want to leave four positions unpopulated.
