Product details

Obsolete — What That Means for Sourcing

The 77313-202-20: This part carries an Obsolete lifecycle status — Amphenol ICC (FCI) no longer manufactures it. Stock is available through independent distribution channels; quantities are lot-specific and confirmed at RFQ. No lead-time commitment can be made without a confirmed source lot.

Pitch and Footprint — Board Fit at a Glance

Dual-row, 20 positions loaded all the way — the breakaway design means the strip was snapped to length, so every pin is present. The unshrouded header relies on the mating receptacle's polarization for correct orientation; watch pin-one alignment on the board layout.

Frequently asked questions

Is 77313-202-20 obsolete?

Yes, 77313-202-20 is listed as Obsolete by Amphenol ICC (FCI). No official successor or replacement part number has been assigned.

What is the equivalent replacement for 77313-202-20?

A functionally similar BERGSTIK header with the same 0.100" pitch, dual-row, 20 positions, and gold plating would need to be cross-referenced by footprint and mating half — this is best handled against a BOM review at RFQ time.

Where can I buy 77313-202-20?

Available through independent distribution channels.
