Molex 0334720442 Equivalent & Substitute Parts

Part Overview

The Molex 0334720442 is a 4-position rectangular connector housing (receptacle) with 4.60mm pitch, designed for crimp termination in free-hanging inline applications. This part is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance requirements. The MX150 33472 series provides multiple active alternatives that maintain electrical and mechanical compatibility while offering improved availability.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0334720442 is determined by strict equivalence across the following parameters:

Connector type (Receptacle)
Contact type (Female Socket)
Number of positions (4)
Pitch specification (0.138" / 4.60mm)
Number of rows (2)
Mounting configuration (Free Hanging In-Line)
Contact termination method (Crimp)
Fastening mechanism (Latch Holder)
Sealed feature requirement
RoHS3 compliance
MSL rating (1)

All three substitute parts—0334724001, 0334724002, and 0334724101—meet these criteria. The primary distinction among substitutes is housing color (Black or Gray) and product status (Active vs. Obsolete). Color selection depends on application requirements and assembly specifications; electrical and mechanical performance remain identical across all variants.

Engineering Selection Recommendations

All three substitute parts (0334724001, 0334724002, 0334724101) are direct functional equivalents to the obsolete 0334720442. Selection criteria are based on the following factors:

Product Status: All substitutes carry Active status, ensuring long-term availability and manufacturing support compared to the obsolete main part.

Compliance: All substitutes maintain ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronics manufacturing and distribution.

Color Selection: Choose 0334724002 (Gray) for applications requiring color matching with the original 0334720442. Select 0334724001 or 0334724101 (Black) where color is not a functional requirement. Both color variants are electrically and mechanically identical.

Availability: 0334724002 (Gray) offers 6,308 units in stock; 0334724001 (Black) provides 44,337 units; 0334724101 (Black) provides 1,982 units. Inventory levels should inform procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Are all three substitute parts electrically interchangeable with the 0334720442?

A: Yes. All substitutes maintain identical electrical specifications: 4-position receptacle configuration, 4.60mm pitch, female socket contacts, crimp termination, and sealed design. Electrical performance is equivalent across all variants.

Q: Does housing color affect connector performance?

A: No. Housing color (Gray or Black) is a cosmetic distinction only. Electrical and mechanical performance is identical between color variants. Color selection should be based on application aesthetics or assembly documentation requirements.

Q: Can I mix color variants in the same assembly?

A: Color mixing is permissible from an electrical and mechanical standpoint. However, assembly specifications or customer requirements may mandate color consistency. Verify design documentation before mixing variants.

Q: What is the significance of the Active product status for the substitutes?

A: Active status indicates the parts are in current production and supported by the manufacturer. This ensures long-term availability, consistent quality, and access to technical support—advantages over the obsolete 0334720442.

Q: Are contacts included with these connector housings?

A: No. All parts (main and substitutes) are housings only. Contacts must be sourced separately and crimped into the housing according to Molex specifications.

Q: Do the substitutes require different mating components?

A: No. All substitutes are compatible with the same mating plug connectors designed for the MX150 33472 series with 4.60mm pitch and 4-position configuration.

Q: What is MSL 1 and why does it matter?

A: Moisture Sensitivity Level 1 (Unlimited) indicates these parts have no moisture sensitivity restrictions. They can be stored indefinitely without special humidity controls, simplifying inventory management and logistics.
