1.27mm Female Headers with Vertical and SMT Terminations
Description
Select by row spacing, body and termination
FH453A–FH453J female headers use a 1.27mm contact pitch along each row. Single-row and dual-row versions have different body widths, termination forms and installed dimensions. FH453H, FH453I and FH453J use 2.54mm between rows, so the along-row pitch alone does not define their mating grid.

Contact arrangements are rows × positions per row. In the formulas below, N is positions per row: total contacts for a single-row part, or half the total for a dual-row part. All formulas give dimensions in millimetres.
