Molex 0022012046 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0022012046 is a 4-position receptacle housing for rectangular connectors with 0.100" (2.54mm) pitch, designed for free-hanging in-line mounting applications. This part is classified as obsolete, making equivalent substitute parts necessary for ongoing procurement and system maintenance. The housing accommodates crimp-terminated contacts and is available in natural color with polyamide insulation material.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0022012046 are qualified based on the following critical parameters:

• Connector Type & Position Count: All substitutes must be receptacle housings with exactly 4 positions
• Pitch Specification: 0.100" (2.54mm) pitch is mandatory for mechanical and electrical compatibility
• Mounting Configuration: Free hanging in-line mounting type must be maintained
• Contact Termination: Crimp termination is required for compatibility with existing contact inventory
• Compliance Standards: ROHS3 compliance and MSL 1 rating are preserved across all qualified substitutes

Two substitute parts meet these criteria: the Molex 0022012041 (direct manufacturer equivalent) and the On Shore Technology 2510-04 (parametric equivalent from alternative manufacturer).

Parameter Comparison

Engineering Selection Recommendations

Molex 0022012041 is the primary substitute for the obsolete Molex 0022012046. Both parts are manufactured by Molex, share identical mechanical and electrical specifications, and maintain full ROHS3 and REACH compliance. The 0022012041 is currently in active production with significantly higher inventory availability (33,457 units). The only difference is housing color (white versus natural), which does not affect functional compatibility. Operating temperature range is -40°C to 105°C, providing extended thermal performance.

On Shore Technology 2510-04 serves as a secondary parametric equivalent from an alternative manufacturer. This part maintains all critical substitution parameters including 4-position configuration, 2.54mm pitch, crimp termination, and free-hanging mounting. It is ROHS3 compliant and MSL 1 rated. The operating temperature range is -25°C to 85°C, which is narrower than the Molex alternative. The insulation material is specified as PA66 (Nylon 6/6) versus standard polyamide. This part is suitable for applications where the narrower temperature range is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0022012041 directly replace the obsolete 0022012046?

A: Yes. Both parts are 4-position receptacle housings with 0.100" pitch, crimp termination, and free-hanging in-line mounting. They are mechanically and electrically interchangeable. The housing color difference (white versus natural) does not affect functional performance.

Q: What are the key differences between the Molex 0022012041 and On Shore 2510-04?

A: Both parts meet the core substitution criteria. The Molex 0022012041 offers an extended operating temperature range (-40°C to 105°C) compared to the On Shore 2510-04 (-25°C to 85°C). The On Shore part uses PA66 insulation material. Selection depends on application temperature requirements and material specifications.

Q: Are contacts included with these housings?

A: No. All three parts (0022012046, 0022012041, and 2510-04) are housings only. Contacts must be procured separately and are not included.

Q: Do all substitute parts meet compliance requirements?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity ratings.

Q: Which substitute should I select for new designs?

A: The Molex 0022012041 is recommended for new designs due to active production status, higher inventory availability, and extended operating temperature range. The On Shore 2510-04 is suitable as an alternative if specific material or cost considerations apply.
