The TE 1-1827862-0 is a 20-position, 2-row receptacle housing from the Dynamic D-1100 series, on a 2.00 mm pitch. The polarizing key prevents inserting the housing into a mismatched header, which saves a harness rework when multiple connectors sit in the same panel.
The 30-position sibling (1-2333134-5) shares the same 2.00 mm pitch, 2-row layout, free-hanging crimp termination, and polarizing key. The difference is position count: 20 positions here versus 30 in the sibling. The 30-position housing also uses a locking ramp for additional retention, while this 20-position version does not list a locking ramp in the spec. If the harness requires 30 circuits at the same pitch, the 1-2333134-5 is the direct step-up. For 20 circuits, this housing is the correct BOM match.
