Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0791077218 is determined by strict alignment with the following critical parameters:

• Connector Type & Contact Configuration: Must be a receptacle with female socket contacts
• Position Count & Pitch: Exactly 38 positions at 0.079" (2.00mm) mating pitch
• Row Configuration: 2 rows with 0.079" (2.00mm) row spacing
• Mounting & Termination: Through-hole solder termination required
• Fastening Mechanism: Push-pull fastening type
• Contact Finish: Gold-plated mating surface
• Operating Temperature: -55°C ~ 125°C range
• Regulatory Compliance: ROHS3 compliant

The Samtec MMS-119-01-S-DV meets all critical substitution criteria. Variations in contact finish thickness, insulation material, and post contact length do not preclude substitution when these parameters remain within acceptable engineering tolerances for the application.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0791077218 and Samtec MMS-119-01-S-DV maintain Active product status and full ROHS3 compliance. Selection between these parts is based on availability and application-specific requirements:

Molex 0791077218 is the primary specification. Current inventory of 849 units supports immediate procurement.

Samtec MMS-119-01-S-DV is a qualified substitute with 797 units in stock. This part exhibits higher current rating per contact (3.9A versus 1A) and increased contact finish thickness on mating surfaces (30.0µin versus 15.0µin), providing enhanced performance margins in high-current or corrosive environments. The Liquid Crystal Polymer (LCP) insulation material offers superior dimensional stability compared to glass-filled thermoplastic.

Both connectors are suitable for automotive, general purpose, and telecommunications applications within the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the Samtec MMS-119-01-S-DV be used as a direct replacement for the Molex 0791077218?

A: Yes. Both connectors share identical mating pitch (0.079"), position count (38), row configuration (2 rows), mounting type (through-hole), termination method (solder), and fastening mechanism (push-pull). Mechanical and electrical compatibility is confirmed.

Q: What are the differences between these two connectors?

A: The primary differences are insulation material (Samtec uses LCP versus Molex glass-filled thermoplastic), contact finish thickness on mating surfaces (Samtec 30.0µin versus Molex 15.0µin), current rating per contact (Samtec 3.9A versus Molex 1A), and post contact length (Samtec 0.115" versus Molex 0.075"). These differences do not affect substitution compatibility for standard applications.

Q: Are there packaging differences between these parts?

A: The Molex 0791077218 packaging is not specified in available data. The Samtec MMS-119-01-S-DV is supplied in tube packaging. Verify packaging requirements with your procurement or assembly process.

Q: Do both connectors meet the same regulatory standards?

A: Yes. Both parts are ROHS3 compliant, classified under ECCN EAR99, and share the same HTSUS code (8536.69.4040). Both operate across the -55°C ~ 125°C temperature range.

Q: Which connector should I select for new designs?

A: Selection depends on application current requirements and environmental conditions. For standard applications at or below 1A per contact, either part is suitable. For applications requiring higher current capacity or enhanced corrosion resistance, the Samtec MMS-119-01-S-DV provides additional performance margin.
