VS102240 Circular Connector Equivalent & Substitute Parts

Part Overview

The VS102240 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 free-hanging, in-line mounting with threaded fastening. The part is currently active in production with 851 units in stock.

Substitute parts become necessary when the primary part experiences extended lead times, inventory constraints, or when design flexibility permits the use of functionally equivalent alternatives from different manufacturers. The substitute identified maintains critical electrical and mechanical compatibility while offering alternative sourcing options.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 97-3106A-20-7P from Amphenol Industrial Operations is classified as a direct functional equivalent based on the following alignment of critical parameters:

Critical Parameter Alignment:

• Connector type: Plug with male pins
• Position count: 8 positions
• Shell size and insert: 20-7 (identical mechanical interface)
• Termination method: Solder cup
• Mounting configuration: Free hanging, in-line
• Fastening mechanism: Threaded coupling
• Operating temperature range: -55°C ~ 125°C (identical thermal envelope)

Supporting Parameter Alignment:

• Contact material: Copper alloy with silver mating finish
• Shell material: Aluminum alloy construction
• Unshielded configuration
• Includes backshell and coupling nut features

The substitute maintains mechanical interchangeability and electrical performance characteristics within the specified operating envelope. Both parts are classified under HTSUS code 8536.69.4020 and carry EAR99 ECCN designation.

Parameter Comparison

Engineering Selection Recommendations

VS102240 (Radiall USA, Inc.) is the primary specification. This part maintains active production status with established inventory availability (851 units in stock). The connector features a chloroprene rubber insert material and green cadmium shell finish. Current rating is specified at 13A. Material flammability rating is UL94 V-0. This part is RoHS non-compliant and carries standard industrial application classification.

97-3106A-20-7P (Amphenol Industrial Operations) serves as a functional substitute with identical mechanical and electrical interface characteristics. This part also maintains active production status with comparable inventory (919 units in stock). The substitute features a diallyl phthalate insert material and olive drab chromate over cadmium shell finish. Current rating specification is not provided in available documentation. This part is also RoHS non-compliant but carries expanded application classification (automotive and industrial). The substitute includes REACH affected status designation.

Both parts satisfy the critical substitution criteria of identical connector type, position count, shell size, termination method, mounting configuration, fastening mechanism, and operating temperature range. The differences in insert material and shell finish represent acceptable variations within the circular connector category for industrial applications. Selection between these parts should be based on specific application requirements, availability, and any design constraints related to insert material compatibility or finish specifications.

Frequently Asked Questions (FAQ)

Q: Can the 97-3106A-20-7P directly replace the VS102240 in existing designs?

A: Yes, the 97-3106A-20-7P provides direct mechanical and electrical interface compatibility. Both connectors share identical shell size (20-7), position count (8), termination method (solder cup), mounting type (free hanging, in-line), and fastening mechanism (threaded). Operating temperature ranges are identical (-55°C ~ 125°C). The substitute maintains the same contact material (copper alloy) and mating finish (silver).

Q: What are the differences between these two parts?

A: The primary differences are: (1) Insert material—VS102240 uses chloroprene rubber (CR) while 97-3106A-20-7P uses diallyl phthalate (DAP); (2) Shell finish—VS102240 features green cadmium while 97-3106A-20-7P has olive drab chromate over cadmium; (3) Application classification—the substitute includes automotive applications in addition to industrial; (4) Current rating—VS102240 specifies 13A while the substitute does not provide this specification in available documentation.

Q: Are there any compliance or regulatory differences?

A: Both parts are RoHS non-compliant and carry EAR99 ECCN designation. Both fall under HTSUS code 8536.69.4020. The substitute carries REACH affected status, which may be relevant for certain supply chain or regulatory requirements. Both parts are classified for industrial applications, though the substitute also includes automotive classification.

Q: What is the significance of the different insert materials?

A: The insert material affects mechanical properties and environmental resistance. Chloroprene rubber (CR) in the VS102240 and diallyl phthalate (DAP) in the 97-3106A-20-7P have different chemical resistance profiles and temperature stability characteristics. Both materials are suitable for the specified operating temperature range (-55°C ~ 125°C). Material selection should be verified against specific application environmental conditions.

Q: Does the shell finish difference affect performance?

A: Shell finish differences (green cadmium versus olive drab chromate over cadmium) primarily affect corrosion resistance and environmental durability rather than electrical performance. Both finishes provide protection for aluminum alloy shells in industrial environments. Selection should consider specific environmental exposure conditions and any design specifications requiring particular finish types.

Q: What is the inventory status for each part?

A: VS102240 has 851 units in stock (new original). The substitute 97-3106A-20-7P has 919 units in stock (new original). Both parts maintain active production status, ensuring continued availability for future requirements.

Q: Are these parts suitable for solder cup termination applications?

A: Yes, both connectors feature solder cup termination, which is suitable for direct soldering to printed circuit boards or cable assemblies. The solder cup design provides a reliable connection method for applications requiring permanent termination without additional connectors or adapters.
