24-Position Hybrid Power Header, Now Obsolete
The TE Connectivity 1-6450122-9 is a 24-position MULTI-BEAM XL header with a hybrid contact layout — 20 signal positions and 4 power positions — on a 0.100" (2.54mm) pitch. This connector is designed for power distribution in backplane or midplane applications where a mix of signal and higher-current power contacts is needed in a single connector body.
Obsolete — Sourced to Order
The 1-6450122-9 is officially obsolete per the manufacturer's lifecycle status. There is no listed direct replacement or successor order code from TE Connectivity.
Board Layout and Mounting
The 0.100" pitch is on a standard grid, so the footprint aligns with common routing rules. The board lock anchors the connector during wave solder and provides shear resistance against cable strain after mating. The mating guide helps align the header with its receptacle during blind-mate assembly — useful in multi-connector backplane panels where visual alignment is limited.
Contact Layout and Duty
The 20 signal positions handle low-current logic or control lines, while the 4 power positions carry the main DC rail or higher-current feeds. The 4-row arrangement (20 loaded positions out of 24 total) means four positions are unpopulated, which may serve as keying or polarization gaps depending on the mating receptacle.
