Product details

The Molex 1729522201 is a 22-circuit receptacle housing from the Micro-Fit 3.0 172952 series.

Critical procurement detail: contacts are separate

A common BOM mistake is ordering only the housing and stopping; the terminal order code is a separate line item.

Retention and polarisation

The housing is polarised (keyed) so it cannot be inserted backward into the mating header; the cavity shape prevents a 180-degree mis-mate. For applications requiring secondary terminal retention, a TPA (Terminal Position Assurance) insert is available in the Micro-Fit 3.0 system, though this housing listing does not include one by default.

Frequently asked questions

Where can I buy Molex 1729522201 and what is the lead time?

The 1729522201 is sourced to order through independent distribution. Submit an RFQ for a firm price and delivery estimate.

Which contacts are used with Molex 1729522201?

The housing accepts Micro-Fit 3.0 female crimp terminals, such as Molex 430300001. Contacts are not included with this housing — they must be ordered separately and crimped onto the wire before insertion.

Does 1729522201 have a lock or retention feature?

Yes, the housing uses a latch holder fastening type that provides a positive, audible lock with the mating header. This latch resists vibration and cable strain in harness applications.
