Product details

Footprint and Board Fit — What the 0.100" Pitch Means

The 40 positions span 20 pins per row, so the PCB footprint requires 20 holes per row at 2.54mm spacing, with a row-to-row spacing of 2.54mm. Compared to the 26-position sibling (77313-118-26LF) or the 16-position (77313-118-16LF), the only difference is the number of positions — all other specs (pitch, plating, current, material, UL94 V-0 rating) are identical. This means the 40-position version is the largest in this subgroup, and the breakaway feature lets you depopulate it for lower-count BOMs without requalifying a new part number.

It is RoHS compliant.

Frequently asked questions

Where can I buy 77313-118-40LF and what is the lead time?

No stock-holding claim is made; each order is quoted individually.

What is the closest functional second-source to 77313-118-40LF?

The closest functional alternative within the same series is the 77313-118-26LF, which is identical in all specs except position count (26 positions vs 40). Both are Active, share the same 0.100" pitch, 3A rating, gold plating, and UL94 V-0 material. For a 40-position requirement, no drop-in replacement exists outside the BERGSTIK® series.
