The 0022122041: The solder tails receive a 100 µinch tin finish for reliable wave-solder wetting.
The post length below the insulator is 0.124" (3.15mm), which determines the through-hole depth on the PCB.
ROHS3 compliant per the current directive.
The pitch is 0.100" (2.54mm), which is the centre-to-centre spacing between adjacent pins. This is the standard KK254 pitch and determines the PCB footprint and mating receptacle compatibility.
The 0.100" pitch and single-row layout are the key compatibility parameters.
