Product details

66-Position Breakaway Header — AMPMODU Mod II

Lifecycle Status — Obsolete, Sourced per RFQ

If your BOM requires a drop-in replacement, a pin-compatible alternative from the same AMPMODU Mod II family (same pitch, row spacing, and unshrouded form factor) would need to match the 66-position count and through-hole termination; verify the contact finish and overall contact length against your mating half.

Mates with standard AMPMODU Mod II receptacles (0.100" pitch, dual-row) — the unshrouded design means the receptacle housing must align the pins; no keying or polarization is built in.

Frequently asked questions

Where can I buy 3-146255-3?

This part is obsolete and not stocked on the shelf. We source it through independent distribution channels — availability and pricing are confirmed when you submit an RFQ against your BOM quantity. No stock-holding claim; quoted per order.

What is the replacement for TE Connectivity 3-146255-3?

TE Connectivity has not published an official replacement for this part number. A functionally equivalent AMPMODU Mod II header with the same 0.100" pitch, 66 positions, dual rows, and unshrouded through-hole form factor would be a drop-in candidate — but verify the contact finish (gold vs tin) and overall contact length against your mating receptacle before committing.
