The 194234-1: A board guide aids alignment during assembly.
Silver-plated copper alloy male pins, 0.250" (6.35 mm) pitch, rated 600VAC. The silver finish supports higher current density than tin at elevated temperatures and provides consistent contact resistance over the operating range.
No direct pin-compatible alternative is listed. The Universal MATE-N-LOK II series includes headers with different position counts (e.g., 2, 3, 6 positions) at the same 0.250" pitch, but the 4-position variant is unique. Verify the required circuit count before selecting a sibling.
RoHS and REACH compliance documentation is available from TE Connectivity for the Universal MATE-N-LOK II series; request the specific certificate for this order code.
