UTS1JC128P Equivalent & Substitute Parts

Part Overview

The UTS1JC128P is an 8-position circular connector receptacle housing manufactured by Souriau-Sunbank by Eaton. This free-hanging (in-line) connector features a bayonet lock fastening mechanism and is designed for male pin integration. The part is actively produced and maintained in inventory, serving applications requiring IP68/IP69K ingress protection and operating across the -40°C to 105°C temperature range. Substitute parts are identified when equivalent electrical and mechanical parameters are required for design flexibility, supply chain alternatives, or inventory optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the UTS1JC128P are identified based on strict equivalence of the following critical parameters:

• Connector Configuration: Receptacle housing for male pins
• Position Count: 8 positions
• Shell Size: 12-8 insert designation
• Contact Specifications: Crimp contact type, size 16
• Mechanical Interface: Free hanging (in-line) mounting with bayonet lock fastening
• Environmental Rating: IP67 or higher ingress protection
• Thermal Range: Operating temperature capability of -40°C minimum and 105°C maximum
• Regulatory Compliance: UL94 V-0 flammability rating and ROHS3 compliance

The substitute part RTS1BS12N8P03 meets all these criteria and is therefore classified as an equivalent alternative.

Parameter Comparison

Engineering Selection Recommendations

Both the UTS1JC128P and RTS1BS12N8P03 are active production parts with equivalent mechanical and electrical specifications for 8-position circular connector receptacle housings. Selection between these parts is based on the following engineering considerations:

UTS1JC128P (Souriau-Sunbank by Eaton): Provides IP68/IP69K ingress protection with operating temperature range of -40°C to 105°C. ROHS3 compliant and UL94 V-0 rated. Suitable for applications requiring the specified thermal and environmental performance envelope.

RTS1BS12N8P03 (Amphenol Sine Systems Corp): Provides IP67/IP69K ingress protection with extended operating temperature range of -40°C to 125°C. ROHS3 compliant and UL94 V-0 rated. The extended upper temperature limit accommodates higher thermal environments. Includes integrated accessories (backshell, clamp ring, nut, O-ring, seal).

Both parts satisfy ROHS3 and REACH compliance requirements. Selection should be based on specific application thermal requirements and whether integrated accessory inclusion is beneficial for assembly workflow.

Frequently Asked Questions (FAQ)

Q: Can RTS1BS12N8P03 directly replace UTS1JC128P in existing designs?

A: Yes, for applications operating within the -40°C to 105°C range. Both parts share identical position count (8), shell size (12-8), contact specifications (crimp, size 16), mounting type (free hanging in-line), and fastening mechanism (bayonet lock). Both meet UL94 V-0 and ROHS3 requirements. The RTS1BS12N8P03 offers extended temperature capability to 125°C, which does not restrict its use in lower-temperature applications.

Q: What is the difference in ingress protection ratings?

A: UTS1JC128P provides IP68/IP69K protection. RTS1BS12N8P03 provides IP67/IP69K protection. IP68 indicates complete dust protection and immersion beyond 1 meter depth. IP67 indicates complete dust protection and immersion up to 1 meter depth. For applications requiring IP68 specifically, UTS1JC128P is the appropriate selection.

Q: Are contacts included with these parts?

A: No. Both UTS1JC128P and RTS1BS12N8P03 are supplied as receptacle housings without contacts. Contacts must be sourced separately and crimped according to manufacturer specifications.

Q: What accessories are included with RTS1BS12N8P03?

A: RTS1BS12N8P03 includes backshell, clamp ring, nut, O-ring, and seal as part of the standard package. UTS1JC128P includes backshell only. Verify accessory requirements for your application before selection.

Q: Are both parts suitable for harsh environmental conditions?

A: Yes. Both parts are rated IP67 or higher and UL94 V-0 flammable, indicating suitability for harsh environments. Operating temperature ranges are -40°C to 105°C (UTS1JC128P) and -40°C to 125°C (RTS1BS12N8P03). Confirm specific environmental exposure requirements against these specifications.

Q: What is the difference in shell material?

A: UTS1JC128P uses polyamide (PA) nylon. RTS1BS12N8P03 uses thermoplastic material. Both materials meet UL94 V-0 flammability requirements. Material selection should be confirmed against chemical exposure and mechanical stress requirements in the target application.
