Parameter Comparison

Engineering Selection Recommendations

Both the VS101758 and 97-3100A20-29P are active production parts with equivalent mechanical and electrical interfaces. Selection between these parts is based on the following engineering considerations:

VS101758 (Radiall USA, Inc.):

• Specified current rating of 13A and voltage rating of 500VAC/700VDC
• Green cadmium shell finish
• Chloroprene rubber insert material
• 1050 units in current inventory

97-3100A20-29P (Amphenol Industrial Operations):

• Olive drab chromate over cadmium shell finish
• Diallyl phthalate insert material
• Current and voltage ratings not specified in available data
• 983 units in current inventory
• Moisture sensitivity level: 1 (Unlimited)
• REACH affected status

Both parts share identical connector geometry, pin configuration, mounting interface, and operating temperature range. The primary differences are in shell finish specification and insert material composition. Selection should be based on application-specific requirements for environmental protection, mechanical durability, and compliance documentation availability.

Frequently Asked Questions (FAQ)

Q: Can the 97-3100A20-29P directly replace the VS101758 in existing designs?

A: Yes. Both connectors share identical mechanical interfaces (17-position, 20-29 shell size, panel mount flange, threaded fastening) and electrical contact specifications (silver-plated copper alloy). The connectors are mechanically and functionally interchangeable for solder cup termination applications.

Q: What is the significance of the different shell finishes between these parts?

A: The VS101758 features green cadmium finish, while the 97-3100A20-29P features olive drab chromate over cadmium finish. Both finishes provide corrosion protection for aluminum alloy shells. Selection depends on environmental exposure requirements and aesthetic specifications for the end application.

Q: Why are current and voltage ratings not specified for the 97-3100A20-29P?

A: The substitute part data provided does not include electrical performance specifications. The VS101758 is rated for 13A at 500VAC/700VDC. For applications requiring confirmed electrical ratings, the VS101758 specifications should be referenced or the substitute manufacturer's technical documentation should be consulted.

Q: What is the difference between Chloroprene Rubber and Diallyl Phthalate insert materials?

A: Both materials are used for connector inserts in industrial applications. Chloroprene rubber (CR) offers elasticity and environmental resistance, while diallyl phthalate (DAP) provides rigidity and thermal stability. Material selection depends on mechanical stress, temperature cycling, and chemical exposure requirements in the specific application.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the VS101758 and 97-3100A20-29P operate across the identical temperature range of -55°C to 125°C, ensuring thermal compatibility in industrial environments.

Q: What does RoHS non-compliant status mean for these connectors?

A: Both parts are classified as RoHS non-compliant, indicating they contain materials or finishes (such as cadmium plating) that exceed RoHS directive thresholds. Applications subject to RoHS regulations require alternative compliant components.

Q: How do the inventory levels compare between these parts?

A: The VS101758 has 1050 units in stock, while the 97-3100A20-29P has 983 units in stock. Both parts maintain adequate inventory for immediate availability.
