Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0791077073 is determined by the following critical parameters:

• Connector geometry: 48-position receptacle with 0.079" (2.00mm) pitch and 2-row configuration
• Electrical interface: Female socket contacts with gold mating finish and solder termination
• Mechanical mounting: Through-hole installation with push-pull fastening
• Environmental compliance: ROHS3 compliance and operating temperature range of -55°C to 125°C

The Samtec MMS-124-01-S-DV meets these core substitution criteria, maintaining identical connector type, position count, pitch, row configuration, mounting method, and termination style. Both parts are active products with ROHS3 compliance and equivalent environmental ratings.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0791077073 and Samtec MMS-124-01-S-DV are active products with equivalent ROHS3 compliance and REACH unaffected status. Selection between these rectangular connectors should be based on:

• Inventory availability: Molex 0791077073 has 816 units in stock; Samtec MMS-124-01-S-DV has 784 units in stock
• Packaging format: Molex is supplied in tube packaging; Samtec is supplied in bulk packaging
• Series compatibility: Molex Milli-Grid 79107 series versus Samtec MMS series
• Regulatory compliance: Both meet identical compliance requirements for ROHS3, REACH, and export classification

Frequently Asked Questions (FAQ)

Q: Are these connectors mechanically interchangeable? A: Yes. Both connectors share identical pitch (0.079"), position count (48), row configuration (2 rows), mounting type (through-hole), and fastening mechanism (push-pull). Physical dimensions and mating interfaces are equivalent.

Q: What are the key differences between these parts? A: The primary differences are manufacturer identity, packaging format (tube versus bulk), insulation material composition, and contact post length specifications. Electrical and mechanical interface parameters remain equivalent.

Q: Can I substitute one part for the other in existing designs? A: Substitution is valid based on matching connector geometry, pitch, position count, mounting method, and termination type. Verify that your application does not have specific series-level requirements or mechanical constraints related to insulation material or contact post dimensions.

Q: Are both parts compliant with automotive and telecommunications standards? A: Both parts are ROHS3 compliant and REACH unaffected. The Molex part explicitly lists automotive, general purpose, and telecommunications applications. Confirm application-specific requirements with your design documentation.

Q: What is the difference in current rating between these parts? A: The Molex 0791077073 is rated at 1A per contact at 125V. The Samtec MMS-124-01-S-DV is rated at 3.9A per contact. Select based on your circuit's current requirements.
