Molex 0349003002 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0349003002 is a 3-position receptacle housing for rectangular connectors with 0.157" (4.00mm) 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. Active alternatives within the MXP120 34900 series provide direct functional equivalence with improved availability and current product status.

Substitute Part Grouping Explanation

Substitution within the MXP120 34900 series is determined by electrical and mechanical compatibility across the following critical parameters: connector type (receptacle), contact type (female blade socket), number of positions (3), pitch (4.00mm), number of rows (1), mounting type (free hanging inline), contact termination method (crimp), and fastening type (latch holder). All substitute parts maintain sealed construction and identical dimensional specifications.

The substitute parts are grouped into two categories:

Direct Functional Equivalents (Identical Specifications): Parts 0349003102 and 0349003101 are functionally identical to the main part across all electrical and mechanical parameters, differing only in packaging format and product status.

Parametric Equivalents (Color Variation): Parts 0349003120 and 0349003121 maintain all functional specifications while offering alternative housing colors (black and gray respectively), providing design flexibility where color coding or aesthetic requirements differ from the original yellow specification.

Engineering Selection Recommendations

For applications currently specified with Molex 0349003002, direct substitution with part 0349003102 or 0349003101 is recommended. Both parts are active products with ROHS3 compliance and identical electrical and mechanical specifications. Part 0349003102 is available in bulk packaging, while part 0349003101 offers the highest current inventory level at 3057 pieces.

When color-coded connector identification is required or design specifications permit alternative housing colors, parts 0349003120 (black) and 0349003121 (gray) provide equivalent functional performance. Part 0349003121 offers the largest available inventory at 6831 pieces.

All substitute parts maintain ROHS3 compliance and MSL rating 1 (unlimited moisture sensitivity level), ensuring compatibility with standard manufacturing and storage environments.

Frequently Asked Questions (FAQ)

Q: Can 0349003102 and 0349003101 be used interchangeably with 0349003002?

A: Yes. Both parts are functionally identical across all electrical and mechanical parameters. The primary differences are packaging format and product status (both are active). Selection between these two should be based on inventory availability and packaging requirements.

Q: What is the difference between the yellow housing (0349003002, 0349003102, 0349003101) and the black/gray alternatives (0349003120, 0349003121)?

A: The housing color is the only difference. All parts maintain identical electrical specifications, pitch, number of positions, contact type, and mounting configuration. Color selection should be based on application requirements for connector identification or design aesthetics.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed—0349003002, 0349003102, 0349003101, 0349003120, and 0349003121—are ROHS3 compliant with MSL rating 1 (unlimited).

Q: What packaging options are available?

A: Part 0349003002 is supplied in standard packaging. Parts 0349003102, 0349003101, 0349003120, and 0349003121 are available in bulk packaging, suitable for high-volume production requirements.

Q: Why is 0349003002 listed as obsolete?

A: Product status reflects manufacturer lifecycle management. Active alternatives within the same MXP120 34900 series provide equivalent functionality with current manufacturing support and improved availability.

Q: Do these housings include contacts?

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