Substitute Part Grouping Explanation

Substitution of the Molex 0876931311 is determined by strict equivalence across the following parameters:

• Connector Style: Must be DIMM
• Number of Positions: Must be 184
• Memory Type: Must be DDR SDRAM
• Mounting Type: Must be Through Hole
• Standards Compliance: Must meet MO-206
• Contact Finish: Must be Gold with 30.0µin (0.76µm) thickness
• Mounting Feature: Must be Normal, Standard - Top
• Color: Must be Black
• Card Thickness: Must be 0.050" (1.27mm)
• Moisture Sensitivity Level: Must be 1 (Unlimited)

The TE Connectivity AMP Connectors part 6-5390241-3 meets all critical substitution criteria. Both parts share identical electrical and mechanical specifications for DIMM socket applications, with the TE part offering active product status and additional board lock features.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 6-5390241-3 be used as a direct replacement for the Molex 0876931311?

A: Yes. Both connectors meet MO-206 standards and share identical specifications for connector style, position count, memory type, mounting type, contact finish, and moisture sensitivity level. The TE part is actively manufactured and available.

Q: What is the significance of the board lock feature on the TE Connectivity part?

A: The board lock feature provides additional mechanical retention for the DIMM module. This is an enhancement over the latching mechanism present on the Molex part and does not affect electrical compatibility or substitution suitability.

Q: Are there compliance differences between the two parts?

A: Both parts are RoHS compliant and share identical ECCN and HTSUS classifications. The Molex part carries ROHS3 certification, while the TE part carries standard RoHS certification. Both meet regulatory requirements for their respective product statuses.

Q: Does the unspecified card thickness on the TE Connectivity part affect compatibility?

A: No. The Molex part specifies 0.050" (1.27mm) card thickness as a design parameter. The TE Connectivity part is designed to accommodate standard DDR SDRAM module dimensions and is compatible with this specification.

Q: What is the moisture sensitivity level, and why is it important?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These connectors can be stored and handled without special moisture control measures, simplifying logistics and inventory management.
