Substitute Part Grouping Explanation

Substitution of the VS101779 with the 97-3106A-18-12P is based on strict equivalence of the following critical parameters:

Mechanical Compatibility:

• Identical connector type (Plug, Male Pins)
• Identical number of positions (6)
• Identical shell size designation (18-12)
• Identical mounting type (Free Hanging, In-Line)
• Identical fastening type (Threaded)
• Identical features (Backshell, Coupling Nut)

Electrical Compatibility:

• Identical termination method (Solder Cup)
• Identical contact material (Copper Alloy)
• Identical contact finish (Silver)
• Identical shielding configuration (Unshielded)

Environmental Compatibility:

• Identical operating temperature range (-55°C ~ 125°C)
• Identical primary shell material (Aluminum Alloy)

Functional Equivalence: Both connectors are circular connector plugs with male pins designed for industrial applications. The 97-3106A-18-12P serves as a direct functional equivalent where the specified parameters align completely.

Parameter Comparison

Engineering Selection Recommendations

VS101779 (Radiall USA, Inc.): Select this part when green cadmium shell finish is specified or required by design documentation. The chloroprene rubber insert material provides specific environmental resistance characteristics. Current rating of 13A and voltage rating of 500VAC/700VDC are explicitly defined. This connector is suitable for applications where Radiall manufacturing and quality standards are contractually mandated.

97-3106A-18-12P (Amphenol Industrial Operations): Select this part when olive drab chromate over cadmium finish is acceptable or preferred. The diallyl phthalate insert material offers alternative mechanical and thermal properties. This connector supports both automotive and industrial applications. The Moisture Sensitivity Level (MSL) rating of 1 (Unlimited) and REACH Affected status provide additional compliance documentation. This part is suitable for applications where Amphenol manufacturing and quality standards are contractually mandated.

Substitution Basis: Both connectors are functionally equivalent for applications requiring 6-position circular connector plugs with male pins, solder cup termination, threaded fastening, and operation across -55°C to 125°C. Selection between these parts is determined by:

• Specified shell finish requirement (green cadmium versus olive drab chromate over cadmium)
• Insert material specification (chloroprene rubber versus diallyl phthalate)
• Manufacturer qualification and contractual requirements
• Supply chain availability and lead time considerations
• Compliance documentation requirements (REACH status, MSL rating)

Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4020) classifications and are RoHS non-compliant.

Frequently Asked Questions (FAQ)

Q: Can the 97-3106A-18-12P directly replace the VS101779 in existing assemblies?

A: Yes, the 97-3106A-18-12P is mechanically and electrically compatible with the VS101779. Both connectors share identical shell size (18-12), pin count (6), termination method (solder cup), fastening type (threaded), and operating temperature range (-55°C to 125°C). The primary differences are shell finish (olive drab chromate over cadmium versus green cadmium) and insert material (diallyl phthalate versus chloroprene rubber). Compatibility depends on whether these material differences are acceptable within the application's design specifications.

Q: What are the key differences between these two connectors?

A: The VS101779 features a green cadmium shell finish and chloroprene rubber insert, while the 97-3106A-18-12P features an olive drab chromate over cadmium shell finish and diallyl phthalate insert. The VS101779 specifies a current rating of 13A and voltage rating of 500VAC/700VDC. The 97-3106A-18-12P lists applications for both automotive and industrial use, whereas the VS101779 is specified for industrial applications only. Both connectors operate across the same temperature range and use identical contact materials and finishes.

Q: Are there electrical performance differences between these connectors?

A: The VS101779 provides explicit electrical ratings of 13A current and 500VAC/700VDC voltage. The 97-3106A-18-12P does not specify current or voltage ratings in the provided data. Both connectors use copper alloy contacts with silver plating and are unshielded. For applications where specific electrical ratings are contractually required, the VS101779 provides documented performance specifications.

Q: How do the insert materials differ in performance?

A: The VS101779 uses chloroprene rubber (CR) insert material, while the 97-3106A-18-12P uses diallyl phthalate (DAP) insert material. Both materials support the identical operating temperature range of -55°C to 125°C. Material selection affects mechanical properties, chemical resistance, and environmental performance. The specific material choice depends on the application's exposure to oils, solvents, humidity, and other environmental factors.

Q: What is the significance of the shell finish difference?

A: The VS101779 features green cadmium finish, while the 97-3106A-18-12P features olive drab chromate over cadmium finish. Both finishes provide corrosion protection for the aluminum alloy shell. Shell finish selection is typically driven by design specifications, aesthetic requirements, or military/aerospace standards. The chromate over cadmium finish on the 97-3106A-18-12P may provide enhanced corrosion resistance in certain environments.

Q: Are both connectors RoHS compliant?

A: No, both the VS101779 and 97-3106A-18-12P are RoHS non-compliant. Both connectors use cadmium-based finishes, which are restricted substances under RoHS regulations. Applications requiring RoHS compliance cannot use either of these connectors without design modification.

Q: What is the Moisture Sensitivity Level (MSL) for these connectors?

A: The VS101779 lists MSL as Not Applicable. The 97-3106A-18-12P lists MSL as 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling. This difference may be relevant for applications with specific moisture control requirements during storage or assembly.

Q: Are these connectors suitable for automotive applications?

A: The VS101779 is specified for industrial applications only. The 97-3106A-18-12P is specified for both automotive and industrial applications. If automotive qualification or performance standards are required, the 97-3106A-18-12P is the appropriate selection.

Q: What is the current inventory status for these parts?

A: The VS101779 has 962 pieces in stock. The 97-3106A-18-12P has 1144 pieces in stock. Both are available as new original parts in bulk packaging.
