The 26-30 AWG wire range means this contact is sized for signal conductors, not power circuits. Section a sample crimp at the specified height and you should see full strand capture across the barrel width — any gap means the wrong die or an undersized wire. ## Housing compatibility and sourcing The 66428-4 socket mates into any Multimate III+ receptacle housing that accepts a stamped socket contact of this series. The Multimate III+ family includes a range of cavity configurations — the contact itself is not keyed, so housing polarization and CPA features are handled by the housing, not the terminal. The active lifecycle status means this contact is still in standard production; no last-time-buy or NRND flags are on record. RoHS compliance is confirmed for the 66428-4. The full product drawing and crimp specification are published under the base product number 66428.","metaTitle":"TE Connectivity 66428-4 Multimate III+ Socket Contact","metaDescription":"TE 66428-4 socket contact, Multimate III+ series, stamped brass with 30.0µin gold plating.
