Substitute Part Grouping Explanation

Substitution of the VS101770 is based on strict equivalence of core electrical and mechanical parameters. The substitute part 97-3106A-18-4S from Amphenol Industrial Operations qualifies as an equivalent based on the following matching criteria:

Matching Parameters:

• Connector type: Plug with female sockets
• Position count: 4 positions
• Shell size: 18-4 (identical insert size)
• Termination method: Solder cup
• Fastening mechanism: Threaded coupling
• Mounting configuration: Free hanging (in-line)
• Shell material: Aluminum alloy construction
• Contact material: Copper alloy with silver mating finish
• Operating temperature range: -55°C ~ 125°C
• Features: Backshell and coupling nut included
• Shielding configuration: Unshielded
• Applications: Industrial use

Both connectors are manufactured to the same dimensional and electrical interface standards, enabling direct substitution in applications where the specified parameters are required.

Parameter Comparison

Engineering Selection Recommendations

Both the VS101770 and 97-3106A-18-4S are active production parts with equivalent electrical and mechanical specifications. Selection between these parts is based on the following engineering considerations:

VS101770 (Radiall USA, Inc.):

• Shell finish: Green cadmium
• Insert material: Chloroprene rubber (CR)
• Current rating: 13A specified
• Voltage rating: 900VAC, 1250VDC specified
• Material flammability: UL94 V-0 rated
• Inventory availability: 1031 units in stock

97-3106A-18-4S (Amphenol Industrial Operations):

• Shell finish: Olive drab chromate over cadmium
• Insert material: Diallyl phthalate (DAP)
• Current and voltage ratings: Not specified in available data
• Material flammability: Not specified in available data
• Moisture sensitivity level: 1 (Unlimited)
• REACH status: REACH affected
• Inventory availability: 888 units in stock
• Broader application scope: Automotive and industrial

Both parts share identical connector geometry, termination method, and operating temperature range. The primary differences are in shell finish color, insert material composition, and specified electrical ratings. Selection should be based on application-specific requirements for electrical performance, environmental conditions, and regulatory compliance needs.

Frequently Asked Questions (FAQ)

Q: Can the 97-3106A-18-4S directly replace the VS101770 in existing designs?

A: Yes. Both connectors share identical shell size (18-4), position count (4), termination method (solder cup), fastening type (threaded), and mounting configuration (free hanging in-line). The mechanical and electrical interface specifications are equivalent, enabling direct substitution.

Q: What are the key differences between these two connector models?

A: The primary differences are shell finish color (green cadmium versus olive drab chromate over cadmium), insert material (chloroprene rubber versus diallyl phthalate), and specified electrical ratings. The VS101770 provides explicit current (13A) and voltage (900VAC, 1250VDC) ratings, while the 97-3106A-18-4S does not specify these values in available documentation.

Q: Are both parts RoHS compliant?

A: No. Both the VS101770 and 97-3106A-18-4S are RoHS non-compliant. Applications requiring RoHS compliance require alternative component selection.

Q: What is the operating temperature range for both connectors?

A: Both connectors operate across the identical temperature range of -55°C to 125°C, supporting industrial applications in extreme thermal environments.

Q: Do these connectors include backshell and coupling nut features?

A: Yes. Both the VS101770 and 97-3106A-18-4S include backshell and coupling nut features as standard components.

Q: What insert materials are used in each connector?

A: The VS101770 uses chloroprene rubber (CR) insert material, while the 97-3106A-18-4S uses diallyl phthalate (DAP) insert material. Both materials are suitable for the specified operating temperature range.

Q: Are these connectors shielded?

A: No. Both connectors are unshielded designs. Applications requiring electromagnetic shielding require alternative component selection.

Q: What is the contact material and finish specification?

A: Both connectors use copper alloy contact material with silver mating finish, providing consistent electrical performance and corrosion resistance.
