40-Circuit C-Grid Vertical Shrouded Header
The 15-80-0401: This is a Molex C-Grid vertical shrouded header, 40 circuits, tin-plated contacts — the description code 'OPT A TIN 40CK' confirms the plating and circuit count.
ROHS3 compliance is confirmed, clearing the EU regulatory requirement for new equipment. Packaged in Box (bulk), typical for through-hole headers shipped in tubes or trays. No official cross-reference or second-source is listed; the C-Grid series is Molex-proprietary, so pin-compatible alternatives would require a board-layout change.
