Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VS101975 is determined by strict equivalence across core electrical and mechanical parameters. The substitute part 97-3106A-18-10S qualifies as a direct equivalent based on the following critical parameters:

Matching Parameters (Substitution Basis):

• Connector Type: Plug, Female Sockets
• Number of Positions: 4
• Shell Size - Insert: 18-10
• Termination Method: Solder Cup
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Threaded
• Shell Material: Aluminum Alloy
• Contact Material: Copper Alloy
• Contact Finish - Mating: Silver
• Shielding: Unshielded
• Features: Backshell, Coupling Nut
• Operating Temperature: -55°C ~ 125°C

Differing Parameters (Non-Critical to Substitution):

• Shell Finish: Green Cadmium (VS101975) vs. Olive Drab Chromate over Cadmium (97-3106A-18-10S)
• Insert Material: Chloroprene Rubber (CR) vs. Diallyl Phthalate (DAP)
• Series Designation: CVS vs. 97
• Manufacturer: Radiall USA, Inc. vs. Amphenol Industrial Operations

The substitute part maintains functional and mechanical compatibility while offering alternative material specifications suitable for different environmental or compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the VS101975 and 97-3106A-18-10S are active products with equivalent mechanical and electrical compatibility for 4-position circular connector plug applications. Selection between these parts should be based on the following factors:

VS101975 (Radiall USA, Inc.):

• Specified current rating of 23A and voltage rating of 500VAC/700VDC provide explicit electrical performance parameters
• Green Cadmium shell finish
• Chloroprene Rubber (CR) insert material
• Established inventory availability

97-3106A-18-10S (Amphenol Industrial Operations):

• Olive Drab Chromate over Cadmium shell finish
• Diallyl Phthalate (DAP) insert material
• REACH Affected status designation
• Moisture Sensitivity Level (MSL) rating of 1 (Unlimited)
• Established inventory availability

Both parts share identical RoHS non-compliant status and EAR99 export classification. The choice between these equivalents depends on application-specific requirements regarding shell finish, insert material properties, and supply chain preferences. No performance degradation occurs when substituting between these parts for applications within the specified operating temperature range of -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can the 97-3106A-18-10S directly replace the VS101975 in existing designs?

A: Yes. Both connectors share identical mechanical dimensions (shell size 18-10), connector configuration (4-position plug with female sockets), termination method (solder cup), and operating temperature range (-55°C to 125°C). The primary differences are shell finish and insert material, which do not affect mechanical or electrical compatibility.

Q: What is the significance of the different insert materials (CR vs. DAP)?

A: Chloroprene Rubber (CR) and Diallyl Phthalate (DAP) are both suitable dielectric materials for circular connector inserts. The choice between them depends on specific application requirements regarding temperature cycling, chemical resistance, and mechanical properties. Both materials are compatible with the -55°C to 125°C operating temperature range.

Q: Does the shell finish difference affect connector performance?

A: Shell finish differences (Green Cadmium vs. Olive Drab Chromate over Cadmium) provide corrosion protection and environmental resistance. Both finishes are suitable for industrial applications. Selection depends on environmental exposure conditions and aesthetic requirements specific to the application.

Q: Are both parts RoHS compliant?

A: No. Both the VS101975 and 97-3106A-18-10S are RoHS non-compliant. If RoHS compliance is required, alternative connector solutions must be evaluated.

Q: What is the REACH status difference between these parts?

A: The 97-3106A-18-10S is designated as REACH Affected, indicating it contains substances of concern under REACH regulations. The VS101975 does not specify REACH status. Applications subject to REACH compliance requirements should verify material composition against specific regulatory obligations.

Q: Are the electrical ratings identical between these parts?

A: The VS101975 specifies a current rating of 23A and voltage rating of 500VAC/700VDC. The 97-3106A-18-10S does not provide explicit electrical ratings in available documentation. For applications requiring confirmed electrical specifications, the VS101975 provides documented performance parameters.

Q: What is the Moisture Sensitivity Level (MSL) significance?

A: The VS101975 lists MSL as Not Applicable, while the 97-3106A-18-10S specifies MSL 1 (Unlimited). MSL 1 indicates the component has unlimited shelf life without moisture control requirements. This difference does not affect substitution compatibility for standard industrial applications.

Q: Can these connectors be used interchangeably in the same assembly?

A: Yes, provided the application does not have specific requirements for shell finish, insert material properties, or electrical rating documentation. Both connectors maintain identical mechanical interfaces and operating characteristics within the specified temperature range.
