The TE Connectivity 171892-1 is a 9-position plug housing from the MIC (Multi-Interlock) series, designed as a free-hanging, in-line connector for wire-to-wire or wire-to-board harness applications. It uses a latch lock for positive retention when mated with the matching receptacle housing — the latch gives an audible click on full engagement, which matters in a production line where incomplete mating is a common rework driver. The housing is moulded in natural polyamide (PA66 / Nylon 6/6) rated for -30°C to 105°C, a range that covers automotive underhood, industrial cabinet, and outdoor telecom enclosures.
Critical Procurement Detail: Contacts Not Included
The single most important fact on this page: the 171892-1 ships as a housing only — contacts are not included. This is a common trap on the BOM line: a buyer orders the housing and assumes the terminals arrive inside the bag. They do not. You need to order the matching female crimp socket terminals separately. The housing accepts the MIC series female socket contacts (crimp termination, 20-24 AWG typical), and those contacts must be ordered as a separate line item. Confirm the terminal part number against your wire gauge before the build starts.
Row Spacing and Position Count for Harness Layout
With 9 positions arranged in 2 rows and a 6.00 mm row spacing, this housing allows larger-diameter wire and greater creepage distance between circuits.
Mating and Termination Checklist
This plug housing mates with the matching MIC series receptacle housing (the female side with the latch lock feature). The termination is crimp — the female socket contacts are crimped onto the wire ends, then inserted into the housing cavities until the terminal latch locks into the housing. The latch lock on the housing itself then secures the mated pair. No soldering, no IDC — pure crimp-and-insert, which is fast on a harness board but requires the correct crimp tool and die set for the terminal.
