Its 0.100" (2.54 mm) pitch matches the standard footprint for many legacy and current header families, making it a direct fit for Micro-MaTch headers and compatible with other 0.1" pitch pin headers.
SMT termination and board layout notes
Surface-mount termination with tin-plated posts suits reflow assembly. The 0.100" row spacing and 0.209" (5.30 mm) insulation height define the keep-out zone on the PCB — the SMT pads sit under the body, so no through-hole clearance is needed. The forked contact design provides a compliant beam that wipes the header pin on insertion, maintaining contact resistance through repeated mating cycles typical of field-serviceable connections.
The 338069-4 covers a 4-position BOM line where the 12-position part would be overkill — but both mate with the same Micro-MaTch headers and use the same PCB footprint per position.
