The TE Connectivity MTA-100 4-643813-1 is an 11-position single-row receptacle that terminates 22 AWG discrete or ribbon cable via IDC — no crimp tool, just a press. The 0.100" (2.54mm) pitch matches the standard MTA-100 header footprint, so it drops into existing board layouts without a layout change.
What mates with this receptacle?
This receptacle mates with any standard MTA-100 0.100" pitch header — through-hole or surface-mount, straight or right-angle, in the same 11-position count. Because it's IDC, the wire side is done in one operation; the board side is a separate header order. Stock both halves or neither — an orphan receptacle with no matching header on the shelf is dead stock.
Is it still in production?
Active lifecycle — no end-of-life notice on record. The MTA-100 series has been a TE standard for decades, and this 11-position variant remains a catalog line item. No official successor has been issued, so the 4-643813-1 is the current BOM part, not a cross to something else.
The 22 AWG wire gauge and IDC termination are fixed; verify the wire type (discrete or ribbon) matches your harness build before committing the BOM line.
