Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0873814484 is determined by strict alignment with the following critical parameters:

  • Connector Configuration: 44-position receptacle with 2-row arrangement
  • Pitch Specification: 0.079" (2.00mm) mating pitch and row spacing
  • Mounting Technology: Surface mount with solder termination
  • Fastening Mechanism: Push-pull engagement system
  • Contact Interface: Gold-plated mating surface with female socket configuration
  • Physical Envelope: 0.177" (4.50mm) insulation height
  • Electrical Performance: Minimum voltage rating of 125V and current capacity of 1.9A per contact
  • Regulatory Compliance: ROHS3 compliance and MSL 1 rating

The Samtec MMS-122-02-F-DV meets these substitution criteria through identical mechanical and electrical specifications across all critical parameters.

Engineering Selection Recommendations

Both the Molex 0873814484 and Samtec MMS-122-02-F-DV connectors are active production parts with ROHS3 compliance and MSL 1 ratings. The Samtec alternative provides an extended operating temperature range to -55°C ~ 125°C and higher current capacity at 3.9A per contact, compared to the Molex specification of 1.9A. Both parts maintain identical mechanical interfaces, pitch specifications, and push-pull fastening systems, ensuring direct board-level compatibility. Selection between these parts should be based on inventory availability and specific application thermal or current requirements within the stated operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the Samtec MMS-122-02-F-DV be used as a direct replacement for the Molex 0873814484?

A: Yes. Both connectors share identical mechanical specifications including 44-position configuration, 0.079" (2.00mm) pitch, 2-row arrangement, surface mount technology, and push-pull fastening. The physical footprint and mating interface are compatible for direct board-level substitution.

Q: What are the key differences between these two parts?

A: The Samtec part offers an extended operating temperature range (-55°C ~ 125°C versus -55°C ~ 105°C) and higher current rating (3.9A per contact versus 1.9A). Both maintain identical electrical and mechanical interfaces for the connector body and contact arrangement.

Q: Are both parts compliant with industry standards?

A: Both the Molex 0873814484 and Samtec MMS-122-02-F-DV are ROHS3 compliant with MSL 1 moisture sensitivity ratings, suitable for standard PCB assembly and storage conditions without special handling requirements.

Q: Does pitch compatibility guarantee mechanical fit?

A: Pitch compatibility combined with identical row spacing, insulation height, and push-pull fastening mechanism ensures mechanical fit. Both parts maintain the same 0.079" (2.00mm) mating pitch and 0.177" (4.50mm) insulation height for direct board compatibility.

Q: What packaging format is available for both parts?

A: Both connectors are supplied in tube packaging suitable for automated pick-and-place assembly processes.
