Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VS101739 are identified based on strict equivalence across critical electrical and mechanical parameters. The substitution logic is based on the following matching criteria:

Critical Matching Parameters:

• Connector type: Receptacle with female sockets
• Position count: 10 positions
• Shell size: 18-1 insert designation
• Termination method: Solder cup
• Mounting configuration: Free hanging, in-line orientation
• Fastening mechanism: Threaded coupling
• Shell material composition: Aluminum alloy construction
• Contact material: Copper alloy with silver mating finish
• Operating temperature range: -55°C to 125°C
• Backshell feature presence
• Unshielded configuration

The substitute part 97-3101A-18-1S from Amphenol Industrial Operations satisfies all critical parameters and is therefore classified as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the VS101739 and 97-3101A-18-1S maintain active product status, indicating ongoing manufacturer support and availability. Both parts carry identical export control classifications (EAR99) and harmonized tariff codes (8536.69.4020), facilitating consistent procurement and regulatory compliance.

The primary distinction between these parts lies in insert material composition and shell finish specification. The VS101739 utilizes Chloroprene Rubber (CR) inserts with green cadmium plating, while the 97-3101A-18-1S employs Diallyl Phthalate (DAP) inserts with olive drab chromate over cadmium plating. Both materials provide suitable electrical insulation and mechanical performance across the specified operating temperature range.

The 97-3101A-18-1S carries REACH Affected status and specifies Moisture Sensitivity Level 1 (Unlimited), indicating broader environmental compliance documentation and unrestricted moisture handling during storage and assembly. The VS101739 lists MSL as Not Applicable.

Both connectors are classified as RoHS non-compliant, reflecting their cadmium-based finishes and historical design specifications. Selection between these parts should be based on specific application requirements regarding insert material properties, shell finish specifications, and regulatory documentation needs.

Frequently Asked Questions (FAQ)

Q: Can the 97-3101A-18-1S directly replace the VS101739 in existing designs?

A: Yes. Both connectors share identical electrical and mechanical specifications across all critical parameters: 10-position configuration, 18-1 shell size, solder cup termination, threaded fastening, and operating temperature range of -55°C to 125°C. Physical and electrical compatibility is established.

Q: What is the difference in insert material, and does it affect performance?

A: The VS101739 uses Chloroprene Rubber (CR) inserts, while the 97-3101A-18-1S uses Diallyl Phthalate (DAP) inserts. Both materials provide adequate electrical insulation and mechanical stability across the specified temperature range. Material selection depends on application-specific requirements for chemical resistance, flexibility, or environmental exposure.

Q: Are there differences in shell finish that affect corrosion resistance?

A: The VS101739 features green cadmium plating, while the 97-3101A-18-1S has olive drab chromate over cadmium plating. Both finishes provide corrosion protection suitable for industrial applications. The chromate layer in the Amphenol part offers additional corrosion resistance in certain environmental conditions. Selection should align with specific environmental exposure requirements.

Q: What is the significance of the REACH Affected status on the 97-3101A-18-1S?

A: REACH Affected status indicates that the part is subject to European Union chemical regulations and requires corresponding compliance documentation. This designation does not affect electrical or mechanical performance but is relevant for supply chain documentation and regulatory compliance in European markets.

Q: How do the current ratings compare between these parts?

A: The VS101739 specifies a current rating of 13A. The 97-3101A-18-1S does not provide a current rating specification in available documentation. For applications requiring explicit current rating verification, the VS101739 specification should be referenced.

Q: Are both parts suitable for automotive applications?

A: The VS101739 is specified for industrial applications. The 97-3101A-18-1S is rated for both automotive and industrial applications, indicating broader environmental and performance qualification. For automotive-specific requirements, the 97-3101A-18-1S provides explicit qualification.

Q: What is the inventory availability for each part?

A: The VS101739 has 853 units in stock. The 97-3101A-18-1S has 1137 units in stock. Both parts maintain active status with adequate inventory for production requirements.

Q: Do both connectors require the same PCB footprint and assembly procedures?

A: Yes. Both connectors share identical mechanical dimensions, solder cup termination specifications, and mounting configurations. PCB layouts and assembly procedures are directly compatible without modification.
