VS101771 Equivalent & Substitute Parts

Part Overview

The VS101771 is an 8-position circular connector plug with male pins and solder cup termination, manufactured by Radiall USA, Inc. as part of the CVS series. This connector is designed for industrial applications requiring threaded fastening and free-hanging (in-line) mounting. The part is currently active in production with 786 units in stock.

Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable, to support supply chain continuity, or to accommodate specific procurement requirements. Substitutes must maintain electrical and mechanical compatibility based on connector position count, shell size, termination type, fastening method, and operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VS101771 is determined by strict alignment with the following core parameters:

Critical Matching Parameters:

• Connector type: Plug with male pins
• Position count: 8 positions
• Shell size: 18-8
• Termination method: Solder cup
• Fastening mechanism: Threaded coupling nut
• Mounting configuration: Free hanging (in-line)
• Shell material: Aluminum alloy
• Contact finish: Silver plating
• Operating temperature range: -55°C to 125°C
• Shielding configuration: Unshielded
• Included features: Backshell and coupling nut

The substitute part 97-3106A-18-8P, manufactured by Amphenol Industrial Operations, meets all critical matching parameters. Both connectors share identical position counts, shell sizes, termination types, fastening methods, and operating temperature specifications. Both feature aluminum alloy shells with silver-plated contacts, unshielded construction, and integrated backshell and coupling nut features.

Parameter Comparison

Engineering Selection Recommendations

Both the VS101771 and 97-3106A-18-8P are active production parts with identical electrical and mechanical specifications for the critical parameters governing connector compatibility. Selection between these parts should be based on the following factors:

Availability and Inventory: The 97-3106A-18-8P currently has 1059 units in stock compared to 786 units for the VS101771, providing greater availability for immediate procurement.

Compliance Status: Both parts are RoHS non-compliant and classified under ECCN EAR99. Both share the same HTSUS code (8536.69.4020), indicating equivalent tariff classification.

Regulatory Considerations: The 97-3106A-18-8P carries REACH Affected status and MSL 1 (Unlimited) rating, whereas the VS101771 lists MSL as Not Applicable. This distinction may be relevant for applications subject to REACH compliance requirements or moisture-sensitive handling protocols.

Shell Finish Variation: The VS101771 features green cadmium plating, while the 97-3106A-18-8P uses olive drab chromate over cadmium. Both finishes provide corrosion protection suitable for industrial applications; selection depends on environmental exposure conditions and aesthetic requirements.

Insert Material Difference: The VS101771 uses chloroprene rubber (CR) inserts, while the 97-3106A-18-8P uses diallyl phthalate (DAP). Both materials are suitable for the specified operating temperature range and industrial applications.

Frequently Asked Questions (FAQ)

Q: Can the 97-3106A-18-8P directly replace the VS101771 in existing assemblies?

A: Yes. Both connectors share identical position counts (8), shell sizes (18-8), termination methods (solder cup), fastening types (threaded), and operating temperature ranges (-55°C to 125°C). The connectors are mechanically and electrically compatible for direct substitution in applications where the specified parameters are required.

Q: What are the differences between these two connectors?

A: The primary differences are shell finish (green cadmium versus olive drab chromate over cadmium), insert material (chloroprene rubber versus diallyl phthalate), and regulatory status (REACH Affected designation for the Amphenol part). Electrical and mechanical performance parameters are identical.

Q: Are there any compliance considerations when substituting between these parts?

A: Both parts are RoHS non-compliant and carry the same ECCN and HTSUS classifications. The 97-3106A-18-8P is designated as REACH Affected, which may require additional documentation for certain procurement scenarios. Verify compliance requirements with your specific application and regulatory jurisdiction.

Q: Does the difference in insert material affect performance?

A: Both chloroprene rubber and diallyl phthalate are suitable for the operating temperature range of -55°C to 125°C specified for these connectors. Material selection does not affect electrical or mechanical compatibility for the stated application parameters.

Q: What is the significance of the MSL rating difference?

A: The VS101771 lists MSL as Not Applicable, while the 97-3106A-18-8P is rated MSL 1 (Unlimited). This indicates the Amphenol part has defined moisture sensitivity specifications, whereas the Radiall part does not specify moisture sensitivity requirements. For applications in controlled environments, this difference is not operationally significant.

Q: Can I use these connectors interchangeably in new designs?

A: Yes. Both connectors meet identical specifications for the critical parameters that determine connector compatibility: 8-position configuration, 18-8 shell size, solder cup termination, threaded fastening, and operating temperature range. Either part is suitable for new designs meeting these specifications.

Q: What should I consider when selecting between these two parts?

A: Consider inventory availability (97-3106A-18-8P has higher stock levels), shell finish requirements (green cadmium versus olive drab chromate), regulatory compliance needs (REACH status), and application environment. Both parts are functionally equivalent for the specified electrical and mechanical parameters.
