Molex 0349004126 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0349004126 is a 4-position rectangular connector receptacle housing with 0.157" (4.00mm) pitch, designed for crimp termination in free-hanging in-line applications. This component is part of the MXP120 34900 series and is actively manufactured. Equivalent and substitute parts within this series share identical electrical and mechanical specifications, differing primarily in color and packaging configurations. Substitutes are necessary when specific color requirements, packaging formats, or inventory availability necessitate alternative part selection while maintaining full functional compatibility.

Substitute Part Grouping Explanation

Substitution within the Molex MXP120 34900 series is determined by strict equivalence across the following critical parameters: connector type (receptacle), contact type (female blade socket), number of positions (4), pitch (0.157" / 4.00mm), number of rows (1), mounting type (free hanging in-line), contact termination (crimp), fastening type (latch holder), sealed features, and operating temperature range (-40°C ~ 125°C).

The substitute parts 0349004115, 0349004116, 0349004120, and 0349004125 are electrically and mechanically equivalent to the main part 0349004126. Variations exist only in color (gray or black) and packaging format (bulk or bag). These variations do not affect functional compatibility or electrical performance. All parts maintain identical pitch, position count, termination method, and environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and ROHS3 compliance. Selection between 0349004126 and its equivalents should be based on color requirement and packaging preference. For gray housings in bulk packaging, 0349004126 and 0349004116 are functionally identical. For black housings, 0349004115 and 0349004125 are available in bulk packaging, while 0349004120 is supplied in bag packaging. Inventory levels vary across all options, with 0349004120 offering the highest stock availability at 7273 pieces. All parts are rated for identical operating temperature ranges and maintain equivalent electrical and mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can 0349004115 replace 0349004126 in my application? A: Yes. Both parts are electrically and mechanically equivalent 4-position receptacle housings with 0.157" pitch, crimp termination, and identical operating temperature specifications. The only difference is housing color (black versus gray). Functional compatibility is complete.

Q: What is the difference between bulk and bag packaging for parts 0349004125 and 0349004120? A: Both parts are functionally identical black receptacle housings. The difference is packaging format only. Bulk packaging (0349004125) and bag packaging (0349004120) do not affect the connector's electrical or mechanical performance. Selection depends on inventory management and handling requirements.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All parts listed—0349004126, 0349004115, 0349004116, 0349004120, and 0349004125—are ROHS3 compliant with MSL rating of 1 (unlimited moisture sensitivity).

Q: Can I mix gray and black housings in the same assembly? A: From an electrical and mechanical standpoint, yes. All parts share identical connector specifications. However, color consistency in final assemblies is typically a design or aesthetic requirement determined by your application specifications.

Q: Which substitute part has the best inventory availability? A: Part 0349004120 has the highest inventory at 7273 pieces. This black housing receptacle in bag packaging is the most readily available option within the MXP120 34900 series.
