Engineering Selection Recommendations

Primary Selection (794953-4): The TE Connectivity AMP Connectors 794953-4 is the specified part with Active product status, RoHS compliance, and natural color housing. This part is recommended for new designs and applications where the VAL-U-LOK series designation is required.

First Alternative (1586018-4): The TE Connectivity AMP Connectors 1586018-4 is a parametric equivalent within the VAL-U-LOK series with identical electrical and mechanical specifications. This part maintains Active product status and RoHS compliance with higher inventory availability (1710 pieces). Selection of this part is appropriate when the base product number 1586018 is acceptable within design specifications.

Second Alternative (0039012041): The Molex 0039012041 is a functionally equivalent connector from the Mini-Fit Jr 5559 series with identical pitch, position count, and mounting configuration. This part is Active with ROHS3 compliance and significantly higher inventory (72146 pieces). The insulation material specification differs (PA66 versus PA), and the REACH status is defined as REACH Unaffected. This part is suitable for applications where cross-manufacturer compatibility is acceptable.

Color Variant Alternatives (2029088-4, 0469990294): The TE Connectivity AMP Connectors 2029088-4 and Molex 0469990294 provide black housing alternatives to the natural color main part. The 2029088-4 carries Obsolete product status and should not be selected for new designs. The 0469990294 is Active with ROHS3 compliance and is suitable when black housing is a functional requirement.

Frequently Asked Questions (FAQ)

Q: Can the 794953-4 be directly replaced with the 1586018-4?

A: Yes. The 1586018-4 maintains all critical electrical and mechanical parameters including connector type, contact configuration, pitch, mounting type, and operating temperature range. Both parts are TE Connectivity AMP Connectors within the VAL-U-LOK series with RoHS compliance and identical MSL ratings.

Q: What is the difference between TE Connectivity and Molex substitute options?

A: TE Connectivity parts (794953-4, 1586018-4, 2029088-4) operate within the VAL-U-LOK series, while Molex parts (0039012041, 0469990294) operate within the Mini-Fit Jr 5559 series. All parts maintain identical pitch (0.165"), position count (4), row configuration (2 rows), mounting type (Panel Mount, Snap-In), and contact termination (Crimp). The primary differences are manufacturer designation, insulation material specification (PA versus PA66), and REACH compliance status.

Q: Is the 2029088-4 suitable for new designs?

A: No. The 2029088-4 carries Obsolete product status and should not be selected for new designs. While it maintains functional compatibility with the 794953-4, Active alternatives such as 1586018-4 or 0039012041 are recommended.

Q: What does the "Contacts Not Included" note mean?

A: All listed parts are connector housings only and do not include the male pin contacts. Contacts must be sourced separately and crimped into the housing according to manufacturer specifications.

Q: Can I use the black housing variants (2029088-4, 0469990294) as direct replacements for the natural housing 794953-4?

A: From an electrical and mechanical standpoint, yes. Both black variants maintain identical connector specifications, pitch, position count, and operating parameters. However, color differences may affect visual identification or aesthetic requirements in the application. Verify that black housing is acceptable within your design specifications before substitution.

Q: What is the inventory advantage of selecting the Molex 0039012041?

A: The Molex 0039012041 has significantly higher inventory availability (72146 pieces) compared to the TE Connectivity 794953-4 (1088 pieces) and 1586018-4 (1710 pieces). This higher availability may reduce lead times for high-volume production requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed parts carry either RoHS Compliant or ROHS3 Compliant status, meeting regulatory requirements for hazardous substance restrictions.
