Product details

0.100" pitch, right-angle, friction lock — board-to-wire header for cost-sensitive harnesses

Current rating depends on wire gauge and ambient temperature — the spec table notes 'Varies by Wire Gauge'. At 25 °C with 22 AWG wire, 5 A per contact is typical for the MTA-100 series, but derate above 85 °C ambient.

Tin-on-tin contact finish — low cycle, cost-optimised

Tin-to-tin interfaces are economical but oxidise over time; they are rated for a few dozen mating cycles. For a one-time board assembly or a connector that is mated once and left, this is fine.

Frequently asked questions

What is the pitch of the 640457-2?

The pitch is 0.100" (2.54 mm), standard for the MTA-100 series.

Is the 640457-2 RoHS compliant?

Yes, it is RoHS compliant per the lifecycle record.

What connector mates with the 640457-2?

It mates with MTA-100 series IDC receptacles and crimp-style housings that accept 0.100" pitch, 2-position, single-row connectors. The friction lock on the header engages the corresponding latch on the receptacle.
