No official replacement part number has been published by the manufacturer. For a pin-compatible alternative, look for other BERGSTIK single-row 20-position unshrouded headers at 0.100\" pitch – the closest functional match would be an active-series header with the same pin length and gold plating grade, but you will need to verify the exact footprint and mating half compatibility."},{"question":"What is the pitch of 77311-101-20?","answer":"The pitch is 0.100\" (2.54mm) – the standard spacing for DIP-compatible headers and receptacles."},{"question":"Where can I buy 77311-101-20?","answer":"No stock-holding claim is made – each lot is sourced per order."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/77311-101-20","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/amphenol/77311-101-20 when reusing this data.
