Substitute Part Grouping Explanation

Substitute parts for the Molex 0342503001 are determined by strict equivalence across the following critical parameters:

Connector Type & Contact Configuration: Receptacle with female socket contacts
Electrical Specifications: 3-position, 0.177" (4.50mm) pitch, single row
Mechanical Interface: Free hanging inline mounting with crimp termination and latch holder fastening
Functional Features: Connector Position Assurance (CPA) and sealed design
Compliance: ROHS3 compliant, MSL 1 rating

All substitute parts maintain these core parameters. Variations in color (black vs. gray) and packaging format (bulk vs. standard) do not affect functional interchangeability for connector housing applications.

Engineering Selection Recommendations

The Molex 0342503001 is obsolete and should be replaced with active production alternatives from the MX150 160073 series. All four substitute parts (1600733105, 1600733106, 1600733115, 1600733116) are functionally equivalent and maintain full ROHS3 compliance and MSL 1 ratings.

Primary Selection: Molex 1600733105 is the direct functional equivalent in black color, matching the original part's appearance and available in bulk packaging with higher inventory levels (11,514 units).

Alternative Selections: Parts 1600733106, 1600733115, and 1600733116 are gray-colored variants of the same housing design. These are suitable for applications where color differentiation is not a functional requirement. Part 1600733116 offers the highest inventory availability (1,801 units) among gray variants in bulk packaging.

All substitute parts are manufactured by Molex and share identical electrical and mechanical specifications with the obsolete 0342503001, ensuring direct interchangeability in connector assemblies.

Frequently Asked Questions (FAQ)

Q: Can I use a gray-colored substitute (1600733106, 1600733115, 1600733116) in place of the black 0342503001?

A: Yes. Color is a cosmetic parameter and does not affect electrical or mechanical function. All substitute parts maintain identical connector specifications, pitch, position count, and fastening characteristics. Color selection should be based on application requirements or assembly identification needs only.

Q: What is the difference between parts 1600733105 and 1600733106?

A: Both parts are functionally equivalent 3-position, 4.50mm pitch receptacle housings from the MX150 160073 series. The only difference is color: 1600733105 is black, while 1600733106 is gray. Electrical and mechanical specifications are identical.

Q: Are there differences between bulk and standard packaging options?

A: Packaging format (bulk vs. standard) affects order quantity and handling but does not alter the connector housing specifications or performance. Part 1600733115 is available in standard packaging, while 1600733105 and 1600733116 are available in bulk packaging. Functional compatibility remains unchanged regardless of packaging format.

Q: Why is the original 0342503001 obsolete?

A: The 0342503001 has been superseded by the MX150 160073 series housings, which offer the same functional specifications with active production status and improved availability. Molex recommends transitioning to the 160073 series for new designs and ongoing production.

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

A: Yes. All substitute parts are electrically and mechanically equivalent. Mixing black (1600733105) and gray (1600733106, 1600733115, 1600733116) variants in the same assembly is functionally acceptable, though color consistency may be preferred for visual identification purposes.

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

A: The substitute parts (1600733105, 1600733106, 1600733115, 1600733116) specify an operating temperature range of -40°C to 125°C. The original 0342503001 does not list an operating temperature specification in the provided data. The substitute parts' temperature rating should be verified against application requirements.
