Board Layout and Signal Routing with 1.27mm Pitch
The 20021521-00010C4LF: The 1.27mm pitch on this dual-row header sets a compact board footprint — 10 positions in two rows at 0.050" (1.27mm) row spacing means the connector occupies roughly 6.35mm along the board edge, leaving room for trace routing between pads.
Surface-Mount Assembly and Packaging Options
Surface-mount termination with a keying slot and pick-and-place feature — the header is compatible with automated placement and reflow soldering; the keying slot prevents incorrect orientation during assembly.
Comparing the 10-Position SMT Header to Siblings
The sibling 20021521-00010D4LF is identical in every spec (10 positions, 1.27mm pitch, gold plating, SMT) except it ships in a Tube instead of Tape & Reel — choose the Tube variant if your assembly line uses tube feeders or you need a smaller quantity without cut-tape handling. The 20-position variant 20021521-00020C4LF doubles the circuit count in the same 1.27mm pitch and row spacing — same gold plating, same current rating, same SMT footprint scaling to 20 circuits for higher-density board-to-cable connections.
