Frequently asked questions
Where can I buy 77311-401-23LF and what is the lead time?
The 77311-401-23LF is sourced and quoted to order against your BOM quantity through independent distribution. Availability and current pricing are confirmed at quote time — no live stock count or lead-time figure is published on this listing.
What does the 77311-401-23LF mate with?
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.
What is the contact plating on the 77311-401-23LF?
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.
What is the current rating of the 77311-401-23LF?
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.
