Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connectors in this category is determined by strict alignment of the following parameters:

• Connector configuration: Receptacle, female socket, 36 positions
• Pitch specification: 0.079" (2.00mm) mating pitch with 2-row configuration
• Mounting and termination: Through-hole solder termination with push-pull fastening
• Contact interface: Gold-plated mating surface for signal integrity
• Environmental compliance: Operating temperature range -55°C ~ 125°C, ROHS3 compliance

The Samtec MMS-118-01-F-DV meets all critical substitution criteria. Both connectors share identical position count, pitch, row configuration, mounting type, termination method, and fastening mechanism. Both maintain ROHS3 compliance and operate within the specified temperature range. Differences in contact finish thickness, insulation material composition, and current rating per contact do not preclude substitution when application requirements are within the electrical specifications of the substitute part.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0791077017 and Samtec MMS-118-01-F-DV maintain Active product status with full ROHS3 compliance and EAR99 export classification. Selection between these parts should be based on:

• Inventory availability: Samtec MMS-118-01-F-DV currently has 1105 units in stock versus 792 units for the Molex part
• Current rating requirements: The Samtec part is rated at 3.9A per contact, while the Molex part is rated at 1A. Applications requiring higher current capacity per contact should specify the Samtec substitute
• Insulation material: Molex uses thermoplastic glass-filled material; Samtec uses liquid crystal polymer (LCP). Both materials are suitable for the specified operating temperature range
• Contact finish thickness: Molex specifies 15.0µin (0.38µm) mating contact finish; Samtec specifies 3.00µin (0.076µm). Both finishes provide adequate gold plating for connector reliability

Frequently Asked Questions (FAQ)

Q: Can the Samtec MMS-118-01-F-DV be used as a direct replacement for the Molex 0791077017?

A: Yes. Both connectors share identical pitch (0.079"), position count (36), row configuration (2 rows), mounting type (through-hole), termination method (solder), and fastening mechanism (push-pull). Physical and electrical compatibility is maintained.

Q: What are the differences in electrical performance between these two connectors?

A: The primary electrical difference is current rating per contact. The Samtec part is rated at 3.9A per contact, while the Molex part is rated at 1A per contact. Applications with current requirements exceeding 1A per contact should use the Samtec substitute. Both connectors operate across the same temperature range (-55°C ~ 125°C) and maintain equivalent voltage performance.

Q: Are there any mechanical differences that affect PCB layout or assembly?

A: Contact length differs slightly: Molex post length is 0.118" (3.00mm) versus Samtec at 0.115" (2.92mm). This 0.003" difference is within standard PCB through-hole tolerance and does not require layout modification. Insulation height remains identical at 0.175" (4.45mm) for both parts.

Q: Do both connectors meet the same compliance standards?

A: Yes. Both the Molex 0791077017 and Samtec MMS-118-01-F-DV are ROHS3 compliant, carry EAR99 export classification, and share the same HTSUS code (8536.69.4040). Moisture sensitivity levels differ (Molex MSL 1 versus Samtec Not Applicable), but both are suitable for standard storage and handling conditions.

Q: Which connector should be selected for new designs?

A: Selection should be based on application-specific requirements. For applications requiring higher current capacity, the Samtec MMS-118-01-F-DV is the appropriate choice. For applications with current requirements at or below 1A per contact, either connector is suitable. Inventory availability and supply chain considerations may also influence selection.
