Substitute Part Grouping Explanation

Substitution of the Molex 0876232013 is determined by strict alignment of the following electrical and mechanical parameters:

• Connector Style & Position Count: Both main and substitute parts must be DIMM connectors with exactly 184 positions to ensure physical and electrical compatibility with DDR SDRAM modules.
• Memory Type: DDR SDRAM specification must be maintained for signal integrity and module recognition.
• Mounting Configuration: Through-hole mounting type and 25° insertion angle must be preserved to ensure proper PCB assembly and module insertion.
• Mechanical Features: Board guide, board lock, and latch mechanisms must be present to provide structural stability and secure module retention.
• Contact Finish: Gold plating ensures reliable electrical contact and corrosion resistance across both parts.
• Compliance: RoHS compliance status and MSL rating must be equivalent or superior to support regulatory and environmental requirements.

The TE Connectivity AMP Connectors part 5390402-7 meets all these criteria and is classified as an active product, providing a direct functional equivalent for the obsolete Molex connector.

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 5390402-7 is the qualified substitute for the Molex 0876232013. Selection is based on the following factors:

• Functional Equivalence: Both connectors share identical electrical specifications for 184-position DDR SDRAM socket applications, with matching insertion angle, mounting type, and mechanical features.
• Active Product Status: The TE Connectivity part is actively manufactured and supported, ensuring long-term availability and supply chain continuity compared to the obsolete Molex connector.
• Compliance Alignment: Both parts meet RoHS requirements and maintain MSL 1 rating, supporting regulatory compliance and environmental standards.
• Contact Durability: The TE Connectivity part features increased gold plating thickness (30.0µin vs. 15.0µin), providing enhanced contact longevity and corrosion resistance.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5390402-7 be used as a direct replacement for the Molex 0876232013?

A: Yes. Both connectors are 184-position DIMM DDR SDRAM sockets with identical mounting type, insertion angle, and mechanical features. They are electrically and mechanically compatible for through-hole PCB applications.

Q: What is the significance of the difference in contact finish thickness?

A: The TE Connectivity part features 30.0µin (0.76µm) gold plating compared to 15.0µin (0.38µm) on the Molex connector. Thicker plating provides extended contact life and improved resistance to wear and corrosion, representing an enhancement over the original specification.

Q: Are there any packaging or form factor differences between these connectors?

A: Both connectors use identical DIMM form factor with 25° insertion angle and standard top-mounted configuration. No physical or dimensional incompatibilities exist between the two parts.

Q: Why is the Molex 0876232013 listed as obsolete?

A: Product obsolescence reflects end-of-life status from the manufacturer. The TE Connectivity 5390402-7 provides continued availability for applications requiring 184-position DIMM DDR SDRAM socket functionality.

Q: Do both connectors meet the same environmental and compliance standards?

A: Yes. Both parts are RoHS compliant and carry MSL 1 (Unlimited) rating, meeting equivalent environmental and moisture sensitivity requirements for industrial and commercial applications.
