Position count across the EI series
The 2-position 171822-2 sits at the low end of the EI receptacle housing range — compare the 6-position 1-1376477-6 (same 2.50mm pitch, plug, latch lock) or the 6-position 1-2069882-6 (5.08mm pitch, dual row) and the 30-position 1-2333134-5 (2.00mm pitch, locking ramp). The 171822-2's single-row 2.50mm pitch and free-hanging mount are shared across the series; position count drives circuit fit.
