The 0.090" (2.29mm) insulation height keeps the pin base low, so the header sits close to the board — useful when the mating connector has a low-profile housing.
ROHS3 compliant, which covers the full substance restriction scope for the European market and most global OEM requirements.
The pitch is 0.100" (2.54mm), which is the standard spacing for the KK254 series and matches the board footprint for most 2.54mm-pitch receptacles.
It mates with any KK254 single-row crimp receptacle housing that accepts 0.100" pitch terminals — for example, the Molex 50-57-9410 10-position housing with the appropriate crimp terminals.
