Molex 0334720401 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0334720401 is a 4-position receptacle housing for rectangular connectors with a 4.60mm pitch, designed for crimp termination in free-hanging inline applications. This part is classified as obsolete, making identification of active equivalent alternatives essential for ongoing procurement and design continuity. The MX150 33472 series provides multiple substitute options that maintain identical electrical and mechanical specifications while offering improved availability through active product status.

Substitute Part Grouping Explanation

Substitution for the Molex 0334720401 is determined by strict equivalence across the following critical parameters:

Connector Type & Contact Configuration: Receptacle housing with female socket contacts
Electrical Interface: 4-position arrangement with 0.138" (4.60mm) pitch
Physical Layout: 2-row configuration with free-hanging inline mounting
Termination Method: Crimp contact termination with latch holder fastening
Environmental Sealing: Sealed housing design
Compliance: ROHS3 compliance and MSL 1 rating

All three substitute parts (0334724001, 0334724002, 0334724101) maintain identical values across these core parameters. Variations exist only in product status (active vs. obsolete) and color specification (black vs. gray), which do not affect functional interchangeability in applications where color is not a design constraint.

Engineering Selection Recommendations

Primary Recommendation: Molex 0334724001

The 0334724001 is the preferred substitute for the obsolete 0334720401. Both parts are black housings with identical electrical and mechanical specifications. The 0334724001 carries active product status with significantly higher inventory availability (44,337 units), ensuring long-term procurement reliability. ROHS3 compliance and MSL 1 rating are maintained.

Secondary Recommendation: Molex 0334724101

The 0334724101 provides an alternative black housing option with active product status. Specifications are identical to the main part. Inventory levels (1,982 units) are lower than the primary recommendation but remain adequate for most applications.

Color Variant: Molex 0334724002

The 0334724002 is functionally equivalent but features a gray housing instead of black. Selection of this part is appropriate only when color specification is not a design constraint or when gray housing is explicitly acceptable in the application.

Frequently Asked Questions (FAQ)

Q: Can the 0334724001 be used as a direct replacement for the 0334720401?

A: Yes. The 0334724001 maintains identical electrical and mechanical parameters across all critical specifications: 4-position receptacle housing, 4.60mm pitch, 2-row configuration, crimp termination, latch holder fastening, and sealed design. The primary difference is product status (active vs. obsolete) and packaging format (bulk).

Q: What is the difference between the three substitute parts?

A: The 0334724001 and 0334724101 are both black housings with identical specifications. The 0334724002 is a gray housing variant. All three are functionally equivalent and interchangeable from an electrical and mechanical standpoint. Selection depends on color requirements and inventory availability.

Q: Are there any compatibility concerns when switching from 0334720401 to an active substitute?

A: No compatibility concerns exist. All substitute parts share the same series designation (MX150 33472), connector type, contact configuration, pitch, and mounting method. Mating connectors and contact sets designed for the 0334720401 are fully compatible with all substitute options.

Q: Does packaging format affect part performance?

A: No. The main part is listed with unspecified packaging, while substitutes are supplied in bulk packaging. Packaging format does not affect electrical or mechanical performance. Bulk packaging is standard for active production parts.

Q: Are all parts ROHS3 compliant?

A: Yes. The main part and all three substitutes are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level), confirming suitability for standard storage and handling conditions.
