Parameter Comparison

Engineering Selection Recommendations

Both the UTS78E4P and RTS78N4P maintain Active product status with current inventory availability, ensuring supply chain continuity. Both components are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for industrial and commercial applications.

The UTS78E4P provides IP68/IP69K ingress protection, while the RTS78N4P provides IP67/IP69K protection. Both ratings exceed minimum dust-tight and waterproof requirements for the specified operating temperature range of -40°C to 105°C. Both connectors maintain identical electrical specifications: 7A current rating and 250V voltage rating with gold-plated mating contacts.

Mechanical compatibility is confirmed across all critical parameters: 4-position configuration, 8-4 shell size, panel mount bulkhead installation with front side nut, bayonet lock fastening, and solder cup termination. Both components feature UL94 V-0 flammability rating and unshielded construction.

Contact material differs between the main part (Brass) and substitute (Copper Alloy), and insert material differs (Polychloroprene versus Chloroprene Rubber), but both material selections maintain functional equivalence within the specified electrical and environmental parameters.

Frequently Asked Questions (FAQ)

Q: Can RTS78N4P directly replace UTS78E4P in existing applications?

A: Yes. Both connectors share identical electrical ratings (7A, 250V), mechanical configuration (4-position, 8-4 shell size, bayonet lock), mounting method (panel mount bulkhead), and termination type (solder cup). Both maintain the same operating temperature range (-40°C to 105°C) and flammability rating (UL94 V-0). The primary difference is ingress protection rating: UTS78E4P provides IP68/IP69K while RTS78N4P provides IP67/IP69K. For applications requiring IP68 specifically, the main part is required.

Q: What is the difference in ingress protection ratings between these parts?

A: The UTS78E4P is rated IP68/IP69K, indicating complete dust protection and waterproof operation under high-pressure water jets. The RTS78N4P is rated IP67/IP69K, indicating complete dust protection and waterproof operation under temporary immersion. Both ratings include IP69K protection against high-temperature, high-pressure water jets. Selection depends on application-specific environmental exposure requirements.

Q: Are the contact materials functionally equivalent?

A: Yes. The UTS78E4P uses Brass contacts while RTS78N4P uses Copper Alloy contacts. Both materials are gold-plated at the mating surface and support identical current (7A) and voltage (250V) specifications. Both materials provide equivalent electrical conductivity and contact reliability within the specified operating parameters.

Q: What is the difference in insert material?

A: The UTS78E4P uses Polychloroprene insert material while RTS78N4P uses Chloroprene Rubber (CR). Both materials are elastomeric compounds that provide equivalent mechanical support and environmental sealing across the specified operating temperature range (-40°C to 105°C). Both materials maintain the required dimensional stability for the 4-position, 8-4 shell size configuration.

Q: Are both parts available in current inventory?

A: Yes. The UTS78E4P has 975 pieces in stock, and the RTS78N4P has 883 pieces in stock. Both are listed as Active products with new original inventory available.

Q: Do both parts meet current regulatory compliance requirements?

A: Yes. Both the UTS78E4P and RTS78N4P are ROHS3 Compliant and REACH Unaffected. Both carry identical ECCN (EAR99) and HTSUS (8536.69.4020) classifications.

Q: What applications are these connectors suitable for?

A: The UTS78E4P is specified for Energy, Instrumentation, Lighting, and Telecommunications applications. The RTS78N4P is specified for Automation, Industrial, Instrumentation, Marine, Telecom, and Transportation applications. Both connectors are suitable for instrumentation and telecommunications; application-specific requirements should determine final selection.
