UTS7128S Equivalent & Substitute Parts

Part Overview

The UTS7128S is an 8-position circular connector receptacle housing manufactured by Souriau-Sunbank by Eaton, designed for panel mount applications with bayonet lock fastening. This component is classified as a Trim Trio® UTS series connector and is currently in active product status with 993 pieces available in inventory. The UTS7128S serves as a female socket receptacle housing for applications requiring IP67/IP69K ingress protection in industrial and harsh environment settings. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across connector type, position count, shell size, mounting configuration, and environmental ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UTS7128S is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Number of Positions: 8
• Contact Type: Crimp
• Contact Size: 16
• Shielding Configuration: Unshielded

Mechanical Compatibility Parameters:

• Shell Size - Insert: 12-8
• Connector Type: Receptacle Housing (Female Socket Type)
• Mounting Type: Panel Mount
• Mounting Feature: Bulkhead - Front Side Nut
• Fastening Type: Bayonet Lock
• Orientation: Normal (N)

Environmental & Compliance Parameters:

• Ingress Protection: IP67/IP69K
• Shell Material: Thermoplastic
• Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

The substitute part RTS712N8S03 maintains all critical parameters listed above, enabling direct functional equivalence in panel mount circular connector applications.

Parameter Comparison

Engineering Selection Recommendations

Both the UTS7128S and RTS712N8S03 are active products with full ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for industrial connector applications. The UTS7128S operates within a -40°C to 105°C temperature range, while the RTS712N8S03 extends this range to -40°C to 125°C, providing additional thermal margin in high-temperature environments. Both connectors maintain identical electrical and mechanical specifications for the 8-position, 12-8 shell size configuration with bayonet lock fastening and IP67/IP69K environmental protection. Selection between these parts should be based on application temperature requirements, manufacturer preference, and inventory availability. The RTS712N8S03 includes integrated gasket, nut, and O-ring components, while the UTS7128S is supplied without contacts or accessories.

Frequently Asked Questions (FAQ)

Q: What determines if a circular connector can substitute for the UTS7128S?

A: Substitution requires equivalence across all critical parameters: 8-position count, 12-8 shell size, crimp contact type with size 16, panel mount bulkhead configuration with bayonet lock fastening, IP67/IP69K ingress protection, thermoplastic housing with UL94 V-0 rating, and unshielded configuration. Deviations in any of these parameters disqualify a part from direct substitution.

Q: Is the RTS712N8S03 a direct pin-for-pin equivalent?

A: Yes. The RTS712N8S03 maintains identical position count (8), shell size (12-8), contact specifications (crimp, size 16), mounting configuration (panel mount bulkhead), and fastening method (bayonet lock). Both connectors are designed for female socket receptacle applications with equivalent mechanical and electrical interfaces.

Q: What is the difference in operating temperature between these parts?

A: The UTS7128S operates from -40°C to 105°C, while the RTS712N8S03 operates from -40°C to 125°C. The RTS712N8S03 provides a 20°C higher upper temperature limit, suitable for applications requiring extended thermal performance.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the UTS7128S and RTS712N8S03 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for industrial electronic components.

Q: What accessories are included with each part?

A: The UTS7128S is supplied as a receptacle housing without contacts or additional components. The RTS712N8S03 includes 4 pieces: 1 connector, 1 gasket, 1 nut, and 1 O-ring, providing a more complete assembly package.

Q: Can these connectors be used in IP67/IP69K rated systems?

A: Yes. Both the UTS7128S and RTS712N8S03 are rated for IP67/IP69K ingress protection, meeting dust-tight and waterproof requirements for harsh industrial environments.

Q: What is the contact size specification for these 8-position connectors?

A: Both connectors use contact size 16 with crimp termination, standardized for the 12-8 shell size configuration in this product category.
