The 2-640456-8: That leaves enough pin projection for a secure mate with standard MTA-100 receptacle housings.
In practice, 22–24 AWG wire typically supports 4–5 A per circuit at 30°C rise; always check the derating curve for your specific gauge.
It is ROHS3 compliant and available through independent distribution.
The pitch is 0.100" (2.54 mm) and it has 28 positions, all loaded, in a single row.
Yes, it is a through-hole header with solder termination. The contact tails are 0.140" (3.56 mm) long for standard PCB mounting.
It mates with MTA-100 series receptacle housings that accept 0.100" pitch female crimp terminals. The friction lock engages with the matching latch on the receptacle.
