The 641937-1: This is a 3-position MTA-156 header body with only 2 positions loaded with male pins — a cost-optimized variant for a 2-wire circuit that still uses the standard 3-position housing.
Rated 600VAC, this header can handle line-voltage power distribution in industrial control panels.
The 641937-1 is available through independent distribution. Submit an RFQ with your target quantity; we source it per order and confirm availability and pricing at quote time. No stock-holding claim — every order is sourced fresh.
The 641937-1 has 3 positions with 2 loaded; the 641937-2 has 3 positions with 3 loaded (all positions populated). Both share the same 0.156" pitch, friction lock, and tin plating. The -1 is a cost-reduced variant for 2-wire circuits.
Yes, the 641937-2 is pin-compatible — same body, same pitch, same lock. The -2 has all 3 positions loaded, so it can replace the -1 in a 2-wire application (the extra pin is simply unused). No board spin required.
Yes, it is ROHS3 compliant.
