Molex 0349004115 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0349004115 is a 4-position rectangular connector receptacle housing with 0.157" (4.00mm) pitch, designed for crimp termination in free-hanging inline applications. This component is part of the MXP120 34900 series and is actively manufactured. Substitute parts are identified based on matching electrical and mechanical parameters within the same product family, allowing for component interchangeability in applications where specific color or packaging requirements differ from the primary specification.

Engineering Selection Recommendations

All substitute parts listed maintain active product status with ROHS3 compliance and MSL Level 1 rating. Selection between equivalent parts should be based on:

Color Requirements: Part 0349004116 provides a gray housing alternative where color coding or visual identification requirements differ from the standard black housing (0349004115, 0349004120, 0349004125).

Packaging Format: Part 0349004120 is supplied in bag packaging, while 0349004115 and 0349004125 are supplied in bulk packaging. Packaging selection depends on inventory management and procurement workflow requirements.

Functional Interchangeability: Parts 0349004115 and 0349004125 are functionally identical black housings in bulk packaging and are directly interchangeable. Part 0349004120 provides the same black housing in alternative bag packaging.

All parts are manufactured by Molex, belong to the MXP120 34900 series, and support identical electrical and mechanical specifications for 4-position, 4.00mm pitch crimp termination applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute part 0349004116 (gray) for 0349004115 (black) in my application?

A: Yes. Part 0349004116 is electrically and mechanically equivalent to 0349004115. The only difference is housing color. Substitution is valid if color coding is not a functional requirement in your application.

Q: What is the difference between parts 0349004115 and 0349004120?

A: Both parts are black 4-position housings with identical electrical and mechanical specifications. The difference is packaging: 0349004115 is supplied in bulk packaging, while 0349004120 is supplied in bag packaging. Functional performance is identical.

Q: Are parts 0349004115 and 0349004125 interchangeable?

A: Yes. Both parts are black housings in bulk packaging with identical specifications. They are direct functional equivalents within the MXP120 34900 series.

Q: Do all substitute parts support the same operating temperature range?

A: Yes. All listed parts operate across the -40°C to 125°C temperature range and are suitable for identical thermal environments.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed are ROHS3 compliant with MSL Level 1 rating, meeting identical environmental and regulatory requirements.

Q: Can I mix substitute parts in the same assembly?

A: Yes. All substitute parts are electrically and mechanically equivalent. Mixed usage is valid from a functional standpoint. Color consistency in the final assembly depends on application-specific requirements.

Q: Do these housings include contacts?

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