Engineering Selection Recommendations

All three Molex substitute parts maintain the core mechanical and electrical interface specifications required for direct substitution with the 3M 953230-2000-AR-PR. The following considerations apply:

Molex 0872633093 is an active product in the Milli-Grid 87263 series with ROHS3 compliance and REACH unaffected status. This part supports both board-to-board and cable applications, offering expanded design flexibility. The reduced insulation height (0.110" vs. 0.169") may require PCB layout verification for clearance compatibility.

Molex 0873813017 and Molex 0873813018 are active products in the Milli-Grid 87381 series with ROHS3 compliance and REACH unaffected status. Both parts feature increased current rating (1.9A vs. 1A) and extended insulation height (0.157" vs. 0.169"), providing improved thermal performance and mechanical robustness. The primary difference between these two parts is the contact finish thickness on mating surfaces: 0873813017 provides 30.0µin (0.76µm) while 0873813018 provides 15.0µin (0.38µm).

All substitute parts are classified as MSL 1 (Unlimited) and carry identical export classification (EAR99) and tariff codes (8536.69.4040) as the original part.

Frequently Asked Questions (FAQ)

Q: Can Molex 0872633093 be used as a direct replacement for the 3M 953230-2000-AR-PR?

A: Yes. Both parts share identical mating pitch (0.079"), position count (30), row configuration (2), surface mount termination, push-pull fastening, and gold contact finish. The primary design consideration is the reduced insulation height of the Molex part (0.110" vs. 0.169"), which requires verification that PCB layout and component clearances remain compatible.

Q: What is the difference between Molex 0873813017 and 0873813018?

A: Both parts are functionally equivalent 30-position receptacles with identical electrical and mechanical specifications. The distinction is the contact finish thickness on mating surfaces: 0873813017 provides 30.0µin (0.76µm) while 0873813018 provides 15.0µin (0.38µm). Selection depends on application-specific contact wear and durability requirements.

Q: Are the Molex substitutes compliant with the same standards as the original 3M part?

A: The Molex 0872633093, 0873813017, and 0873813018 all carry ROHS3 compliance and REACH unaffected status. The original 3M part does not specify these certifications. All parts share identical MSL rating (1 - Unlimited), ECCN classification (EAR99), and HTSUS code (8536.69.4040).

Q: What is the voltage rating difference between the original and substitute parts?

A: The 3M 953230-2000-AR-PR is rated for 1000VDC, while the Molex substitutes are rated for 125VAC or 125V. Application voltage requirements must be verified to ensure the substitute part meets system specifications.

Q: Can the Molex 0872633093 be used in cable applications?

A: Yes. The Molex 0872633093 supports both board-to-board and cable connectivity styles, whereas the original 3M part and the other Molex substitutes (0873813017, 0873813018) are specified for board-to-board applications only.

Q: What packaging options are available for these substitute parts?

A: The Molex 0872633093 packaging is not specified in the available data. The Molex 0873813017 and 0873813018 are supplied in Tube packaging. The original 3M part is supplied in Cut Tape (CT) packaging.
