Frequently asked questions

Where can I buy 4-103777-0?

We source this obsolete part through independent distribution. Submit an RFQ for current availability and pricing.

What is the replacement for 4-103777-0?

No official replacement is recorded from TE Connectivity. A pin-compatible alternative would need to match the 80-position, 2.54mm pitch, dual-row, unshrouded footprint. Cross-reference to other AMPMODU Mod II headers or generic 0.100" breakaway headers is possible, but no direct drop-in is confirmed.
