Substitute Part Grouping Explanation

Substitute parts for the Molex 0349003001 are determined by strict equivalence across the following critical parameters:

Connector type: Receptacle
Contact type: Female blade socket
Number of positions: 3
Pitch: 0.157" (4.00mm)
Number of rows: 1
Mounting type: Free hanging (in-line)

Engineering Selection Recommendations

All three substitute parts (0349003101, 0349003120, 0349003121) are functionally equivalent to the obsolete 0349003001 across all critical electrical and mechanical parameters. Selection among these alternatives should be based on the following factors:

Product Status: Parts 0349003101, 0349003120, and 0349003121 are all active products with confirmed current manufacturing status, ensuring long-term availability and supply chain stability compared to the obsolete 0349003001.

Compliance: All substitute parts maintain ROHS3 compliance and MSL 1 rating, meeting the same regulatory and environmental requirements as the original part.

Color Specification: Choose based on application requirements. The 0349003101 maintains yellow color matching the original 0349003001. The 0349003120 (black) and 0349003121 (gray) provide alternative color options where color coding or visual identification requirements differ.

Packaging: The 0349003101, 0349003120, and 0349003121 are supplied in bulk packaging, differing from the original part's packaging specification. Confirm packaging compatibility with procurement and assembly processes.

Frequently Asked Questions (FAQ)

Q: Are the substitute parts 0349003101, 0349003120, and 0349003121 electrically and mechanically interchangeable with 0349003001?

A: Yes. All substitute parts share identical electrical and mechanical specifications including connector type, contact type, position count, pitch, mounting configuration, termination method, and fastening mechanism. They are direct functional equivalents within the MXP120 34900 series.

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

A: The substitute parts differ only in housing color. Part 0349003101 is yellow (matching the original), 0349003120 is black, and 0349003121 is gray. All other specifications remain identical.

Q: Why is the original part 0349003001 listed as obsolete?

A: The 0349003001 has been discontinued by Molex. The active substitute parts ensure continued availability for applications requiring this connector housing configuration.

Q: Can I use any of the three substitute parts interchangeably in my application?

A: Yes, provided your application does not have specific color requirements. All three parts are electrically and mechanically equivalent and will function identically in the same circuit or assembly.

Q: What is the operating temperature range for the substitute parts?

A: The substitute parts 0349003101, 0349003120, and 0349003121 operate across -40°C to 125°C. This specification was not provided for the original 0349003001.

Q: Are there any packaging considerations when switching from 0349003001 to the substitute parts?

A: Yes. The original 0349003001 packaging specification differs from the substitute parts, which are supplied in bulk packaging. Confirm that bulk packaging is compatible with your procurement, storage, and assembly processes.

Q: Do all parts meet RoHS3 compliance?

A: Yes. The original part 0349003001 and all substitute parts (0349003101, 0349003120, 0349003121) are RoHS3 compliant with MSL 1 rating.
