9-Position, 3-Row Receptacle Housing for Universal MATE-N-LOK II
The TE Connectivity 770054-1 is a 9-position receptacle housing from the Universal MATE-N-LOK II series, arranged in 3 rows with 0.250" (6.35mm) row spacing.
You must order the matching Universal MATE-N-LOK II crimp terminals — available in both male and female variants — to populate the cavities. The housing accepts the standard series contact for 20-14 AWG wire range, terminated by a standard crimp tool. Without the contacts, this is just the shell; factor the terminal order code and quantity into the BOM.
Row Spacing and Cavity Layout
The 0.250" (6.35mm) row spacing is a defining dimension for the Universal MATE-N-LOK II series. With 3 rows and 9 total positions, the cavity arrangement is 3 per row. This spacing provides adequate creepage for the voltage ratings typical of the series (600 V AC/DC per the family specification) while keeping the housing compact enough for dense harness routing. The 3-row layout also gives a wider mating face than a single- or dual-row equivalent, distributing insertion forces across more plastic during mate and unmate.
