Product details

The 1-770874-0 is a TE Connectivity Mini-Universal MATE-N-LOK header, 4 positions in 2 rows at 0.163" (4.14mm) pitch, designed for board-to-cable/wire applications. Rated at 600VAC, the header suits line-voltage control circuits, power supplies, and industrial equipment where the insulation system must withstand mains-level stress. The locking ramp fastening type provides audible and tactile confirmation of full mate, critical for applications subject to shock or continuous vibration.

Through-Hole Solder Termination and Tin-Plated Contacts

Contact material is brass, and the contact shape is circular, compatible with standard Mini-Universal MATE-N-LOK crimp terminals. The insulation color is white, aiding visual identification during harness assembly.

Frequently asked questions

What is the pitch of 1-770874-0?

The mating pitch is 0.163" (4.14mm), with the same row spacing. This is a coarse pitch that simplifies PCB routing for high-voltage or high-current traces.

Is 1-770874-0 RoHS compliant?

Yes, it is ROHS3 compliant.

What is the mating connector for 1-770874-0?

This header mates with Mini-Universal MATE-N-LOK receptacle housings that accept the matching crimp terminals. The locking ramp on the header engages with the latch on the receptacle for a secure mate.

What is the current rating for 1-770874-0?

The current rating varies by wire gauge, as stated in the spec table. The limiting factor is the attached wire and crimp terminal, not the header itself.
