Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0950032441 is determined by strict alignment of the following parameters:

• Connector type (Jack)
• Contact configuration (4P4C / RJ9, RJ10, RJ22)
• Mounting method (Through Hole)
• Orientation (Vertical)
• Termination method (Solder)
• Shielding classification (Unshielded)
• Electrical rating (Cat3)
• Presence of board lock feature
• Contact finish (Gold plated)
• Operating temperature range compatibility
• Regulatory compliance (ROHS3, REACH Unaffected)

The Molex 0955032441 meets all these criteria and is identified as a direct substitute. Both parts share identical functional specifications for connector type, contact configuration, mounting, orientation, termination, shielding, rating, and feature set. Differences in contact material composition and housing material do not affect electrical or mechanical compatibility within the specified operating parameters.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0955032441 is the direct substitute for the obsolete Molex 0950032441. Both parts maintain identical electrical and mechanical specifications across all critical parameters: connector type, contact configuration, mounting method, orientation, termination, shielding, and rating classification.

The substitute part offers the advantage of active product status, ensuring continued availability and supply chain support. Both parts carry ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements. The operating temperature range of the substitute extends to 85°C compared to 80°C for the original part, providing additional thermal margin in applications operating near the upper temperature limit.

Selection of the 0955032441 is appropriate for new designs and for replacement in existing applications where the original 0950032441 is no longer procurable.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0955032441 be used as a direct replacement for the 0950032441 in existing designs?

A: Yes. Both parts share identical connector type, contact configuration (4P4C), mounting method (through hole), orientation (vertical), termination (solder), shielding (unshielded), and rating (Cat3). The substitute meets all functional and mechanical requirements for direct substitution.

Q: What is the difference in contact material between these two parts?

A: The original part uses phosphor bronze contacts, while the substitute uses copper alloy contacts. Both are gold-plated with compatible electrical properties for Cat3 applications.

Q: Does the housing material difference affect compatibility?

A: No. The original part uses polyester glass-filled housing, while the substitute uses liquid crystal polymer (LCP) glass-filled housing. Both materials provide equivalent mechanical performance and environmental protection for the specified operating conditions.

Q: What is the significance of the product status difference?

A: The original 0950032441 is classified as obsolete, indicating discontinued production and limited availability. The substitute 0955032441 is active, ensuring ongoing supply and support for procurement and design continuity.

Q: Are there any temperature-related considerations when substituting?

A: The substitute part supports an operating temperature range of -40°C to 85°C, compared to -40°C to 80°C for the original. This provides an additional 5°C margin at the upper temperature limit, which may be beneficial in thermally demanding applications.

Q: Do both parts meet current regulatory compliance standards?

A: Yes. Both the original and substitute parts are ROHS3 compliant and REACH Unaffected, meeting current regulatory requirements for electronic components.

Q: What packaging format is available for the substitute part?

A: The substitute part 0955032441 is supplied in tray packaging, suitable for automated assembly and high-volume production environments.
