21-Position MIC Plug Housing — What It Is
The TE Connectivity 172501-1 is a 21-position plug housing from the MIC (Multi-Interlock) series, designed as a free-hanging (in-line) wire-to-wire or wire-to-board interconnect. It accepts female socket contacts installed via crimp termination, with the latch lock providing positive retention when mated to the matching receptacle.
Contacts Not Included — Order Separately
This housing ships without contacts — the listing explicitly notes contacts are not included. The buyer must source the matching female crimp socket terminals separately for the wire gauge and current rating the application requires. The MIC series uses standard TE crimp contacts; verify the contact part number against the wire size before committing the BOM line.
