The 3.00mm pitch and 0.118" row spacing set the board footprint for a 24-position, 2-row header. The 0.125" post length (3.18mm) suits standard through-hole boards; the press-fit and solder termination options give flexibility for both reflow and wave-solder assembly.
The solder tails are finished with 100.0 µinch tin-lead, compatible with standard leaded solder processes.
Yes, the 2-794631-4 is marked Obsolete by TE Connectivity. No direct pin-compatible replacement has been published under the Micro MATE-N-LOK series. For a BOM that requires this exact part, sourcing is through independent channels — quantities and lead time are confirmed per RFQ. If a design change is acceptable, a current-production header with the same 3.00mm pitch and 24 positions from the same series may be evaluated, but the footprint and locking features should be verified against the original.
Yes, the header includes a locking ramp fastening type.
