Molex 0334721345 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0334721345 is a 12-position rectangular connector receptacle housing designed for the MX150 33472 series. This component functions as a housing for female socket contacts with a 0.138" (3.50mm) pitch configuration and is classified as a free-hanging, in-line mounted connector. The part is currently active in production with 1087 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across alternative part numbers, enabling component interchangeability in applications where specific housing characteristics or availability requirements necessitate alternative sourcing.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0334721345 is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle housing with female socket contacts
• Electrical Interface: 12-position configuration at 0.138" (3.50mm) pitch with 2-row arrangement
• Mechanical Interface: Free-hanging, in-line mounting with crimp termination and latch holder fastening
• Sealing & Protection: Sealed housing design
• Series Compatibility: MX150 33472 series designation

The substitute part Molex 0334721345 maintains all critical electrical and mechanical parameters. Variations in housing color (black versus gray) and insulation material composition do not affect functional interchangeability within the MX150 33472 connector system, as these characteristics are secondary to the core interface specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0334721345 and Molex 0334721207 are active production components with identical electrical and mechanical interface specifications. Selection between these parts should be based on the following factors:

Molex 0334721345 (Black Housing)

• Current inventory: 1087 units
• Insulation material: Syndiotactic Polystyrene (SPS), Glass Filled
• Moisture Sensitivity Level: Not Applicable
• Suitable for applications where black housing color is specified or preferred

Molex 0334721207 (Gray Housing)

• Current inventory: 4771 units
• Insulation material: Polyamide (PA), Nylon, Glass Filled; Syndiotactic Polystyrene (SPS)
• Operating Temperature: -40°C ~ 150°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS3 Compliant
• REACH Unaffected
• Suitable for applications where gray housing color is specified, higher inventory availability is required, or explicit RoHS3 compliance documentation is needed

Both parts are EAR99 classified and maintain full compatibility within the MX150 33472 connector system.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0334721207 be used as a direct replacement for the Molex 0334721345?

A: Yes. Both parts maintain identical electrical and mechanical interface specifications, including connector type, contact configuration, pitch, mounting method, and fastening mechanism. The housing color and insulation material composition differences do not affect functional interchangeability within the MX150 33472 series.

Q: What is the primary difference between these two connector housings?

A: The primary differences are housing color (black versus gray) and insulation material composition. The 0334721345 uses Syndiotactic Polystyrene (SPS) with glass fill, while the 0334721207 uses Polyamide (PA) with nylon and glass fill, plus SPS. These material differences do not impact the core electrical or mechanical interface.

Q: Does the Molex 0334721207 have better environmental specifications?

A: The 0334721207 includes documented operating temperature range (-40°C ~ 150°C), RoHS3 compliance, and REACH unaffected status. The 0334721345 does not include these specifications in the provided data. If environmental compliance documentation or temperature range specifications are required, the 0334721207 is the appropriate selection.

Q: Are there packaging differences between these parts?

A: Yes. The 0334721345 is supplied with unspecified packaging, while the 0334721207 is supplied in bulk packaging. Packaging selection should align with procurement and assembly workflow requirements.

Q: What is the Moisture Sensitivity Level difference?

A: The 0334721345 has MSL listed as Not Applicable, while the 0334721207 has MSL 1 (Unlimited). This indicates the 0334721207 has no moisture sensitivity restrictions during storage and handling.

Q: Can I mix these connector housings in the same assembly?

A: Yes. Since both parts are electrically and mechanically equivalent within the MX150 33472 series, they can be used interchangeably in the same assembly. However, housing color consistency may be a design or aesthetic consideration depending on application requirements.
