UTS1JC103S Equivalent & Substitute Parts Reference

Part Overview

The UTS1JC103S is a 3-position circular connector receptacle housing manufactured by Souriau-Sunbank by Eaton, part of the Trim Trio® UTS series. This free-hanging (in-line) receptacle housing is designed for female socket applications with bayonet lock fastening and IP68/IP69K ingress protection rating. The component is currently active in production with 2400 units in stock. Alternative equivalent parts are identified to support procurement flexibility, supply chain continuity, and application-specific requirements where substitution parameters align with the original specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UTS1JC103S is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Receptacle Housing for female sockets
• Number of Positions: 3-position configuration
• Shell Size - Insert: 10-3 specification
• Contact Type: Crimp contacts
• Contact Size: 16
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Bayonet Lock
• Orientation: Normal (N)
• Contact Shape: Circular
• Shielding: Unshielded
• Contacts Not Included: Applies to all equivalent parts

Allowable Variation Parameters:

• Shell Material: Polyamide (PA), Nylon or Thermoplastic
• Ingress Protection: IP67/IP69K or IP68/IP69K (both meet waterproof/dust-tight requirements)
• Operating Temperature: -40°C minimum and 105°C minimum upper limit
• Insert Material: Polyamide (PA), Nylon or Thermoplastic
• Compliance certifications: ROHS3 Compliant, REACH Unaffected, EAR99

The substitute part RTS1BS10N3S03 meets all mandatory parameters and operates within allowable variations, qualifying it as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

UTS1JC103S (Souriau-Sunbank by Eaton): Select this part when Trim Trio® UTS series continuity is required or when the lower operating temperature ceiling of 105°C is sufficient for the application. This part is ROHS3 compliant and REACH unaffected. Current inventory of 2400 units supports immediate availability.

RTS1BS10N3S03 (Amphenol Sine Systems Corp): Select this part as a functional equivalent when ecomate® Aquarius™ series compatibility is acceptable or when extended operating temperature capability to 125°C is beneficial. This part is ROHS3 compliant and REACH unaffected. The substitute includes accessory components (clamp ring, nut, O-ring, seal) in addition to the connector and backshell. Current inventory of 1031 units is available. The IP67 rating meets the same dust-tight and waterproof requirements as the original IP68 specification for this connector category.

Both parts satisfy identical electrical and mechanical interface requirements. Selection between them depends on series preference, temperature operating range requirements, and accessory inclusion needs.

Frequently Asked Questions (FAQ)

Q: Can RTS1BS10N3S03 directly replace UTS1JC103S in existing assemblies?

A: Yes, for applications where the connector interfaces with mating plugs and the operating temperature does not exceed 105°C. Both parts share identical shell size (10-3), position count (3), contact type (crimp, size 16), fastening method (bayonet lock), and mounting configuration (free hanging in-line). The RTS1BS10N3S03 provides extended temperature capability to 125°C, which does not create incompatibility with applications designed for 105°C operation.

Q: What is the difference in ingress protection between IP68 and IP67?

A: Both ratings provide dust-tight and waterproof protection suitable for this connector category. IP68 specifies continuous immersion at depths greater than 1 meter; IP67 specifies immersion up to 1 meter depth. For typical circular connector applications, both ratings deliver equivalent environmental sealing performance.

Q: Does the RTS1BS10N3S03 include contacts?

A: No. Like the UTS1JC103S, the RTS1BS10N3S03 is supplied as a receptacle housing without contacts. Contacts must be procured separately and crimped into the insert.

Q: What accessories are included with RTS1BS10N3S03?

A: The RTS1BS10N3S03 includes 6 pieces: 1 connector, 1 backshell, 1 clamp ring, 1 nut, 1 O-ring, and 1 seal. The UTS1JC103S is supplied as bulk packaging without these additional components.

Q: Are both parts RoHS3 compliant?

A: Yes. Both UTS1JC103S and RTS1BS10N3S03 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the shell material difference?

A: UTS1JC103S uses Polyamide (PA) Nylon; RTS1BS10N3S03 uses Thermoplastic. Both materials achieve UL94 V-0 flammability rating and provide equivalent mechanical and environmental performance for this connector application.

Q: Can these parts be used interchangeably in new designs?

A: Yes. Both parts meet identical functional specifications for 3-position, 10-3 shell size, crimp contact, bayonet lock receptacle housings. Design selection should consider series preference (Trim Trio® UTS versus ecomate® Aquarius™), operating temperature range (105°C versus 125°C maximum), and accessory requirements.
