Product details

MX150 33472 16-Circuit Receptacle Housing

The Molex 0334721770 is a 16-circuit receptacle housing from the MX150 33472 series, designed for wire-to-wire and wire-to-board connections in sealed automotive and industrial environments. The 0.138" (3.50mm) pitch gives enough spacing for 18-22 AWG power and signal circuits without crowding the crimp pockets. A latch holder with Connector Position Assurance (CPA) locks the pair against vibration, and the glass-filled nylon housing handles -40°C to 150°C, making it a fit for underhood or engine-adjacent harnesses.

What the CPA and Temperature Range Mean for the Harness

The Connector Position Assurance (CPA) feature is a secondary lock that engages after the primary latch, preventing accidental unmating from thermal cycling or vibration. In an automotive harness running near the engine block or transmission, that secondary lock is what keeps the signal path intact when the chassis is shaking. The -40°C to 150°C operating range confirms the housing material — a blend of glass-filled polyamide and syndiotactic polystyrene — can take the thermal shock of a cold start in winter and the soak heat of a summer engine bay without cracking or softening.

Frequently asked questions

Where can I buy the Molex 0334721770 available via RFQ confirmation?

The Molex 0334721770 is available to order through independent distribution.

Is the Molex 0334721770 a housing only or does it include contacts?

The 0334721770 is a housing only — contacts are not included. The listing explicitly notes 'Contacts Not Included', so you will need to order the matching MX150 female crimp terminals separately.

What is the pitch of the Molex 0334721770?

The pitch is 0.138" (3.50mm), which is wider than the common 2.54 mm or 3.00 mm automotive connectors. That 3.50 mm spacing provides extra creepage for higher-voltage circuits in the MX150 platform.

Is the Molex 0334721770 compatible with MX150 male connectors?

Yes, this receptacle mates with the MX150 male plug housing (33471 series) and the matching male header. The latch holder and CPA feature are designed to engage with the male-side lock ramp.
