Availability and current pricing are confirmed at quote time — no live stock count or lead-time figure is published on this listing."},{"question":"What does the 77311-401-23LF mate with?","answer":"The 77311-401-23LF is an unshrouded 23-position 0.100\" (2.54 mm) pitch male pin header — it mates with any standard 23-position 0.100\" pitch female IDC or machine-pin receptacle. Verify the mating half carries exactly 23 positions; a miscount in position count is the most common fit failure on unshrouded headers of this type."},{"question":"What is the contact plating on the 77311-401-23LF?","answer":"Both the mating face and the solder-post side carry tin plating at 78.7 µin (2.00 µm) — the same finish grade on both surfaces, which is consistent with the solder-side reworkability and signal-duty profile of this header."},{"question":"What is the current rating of the 77311-401-23LF?","answer":"Rated 3 A per contact. This is a per-contact figure — the limiting factor in high-current applications is thermal accumulation from adjacent circuits, not the individual pin rating itself."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/77311-401-23LF","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/77311-401-23LF when reusing this data.
