Product details

The TE Connectivity 3-644540-8 is an 8-position MTA-100 IDC receptacle designed for mass-termination of discrete or ribbon cable to a board header.

IDC Termination and Wire Gauge

The feed-through feature lets you daisy-chain multiple receptacles on the same continuous wire run, which is useful for distributing power or signals to several points on a cable without splicing.

Tin-plated contacts at 80.0µin (2.03µm) thickness give adequate corrosion resistance for indoor equipment; the thick tin layer also withstands the wiping action during multiple insertion cycles better than a thin flash.

Where can I buy 3-644540-8 and get a price?

Submit a request for your target quantity and we will confirm availability and current pricing at quote time.

What is the pitch of 3-644540-8?

The pitch is 0.100" (2.54mm), which is the standard MTA-100 spacing and matches the mating header's pin row.

Is 3-644540-8 RoHS compliant?

Yes, it is ROHS3 compliant.

What wire gauge is used with 3-644540-8?

It is designed for 22 AWG discrete or ribbon cable, terminated via IDC.

What is the mating header for 3-644540-8?
