UTS718-32S Equivalent & Substitute Parts

Part Overview

The UTS718-32S is a 32-position circular connector receptacle housing manufactured by Souriau-Sunbank by Eaton. This panel-mount component is designed for female socket applications with bayonet lock fastening and IP67/IP69K ingress protection. The part is currently active in production with 716 units in stock. Alternative models become necessary when supply constraints occur, when specific operational temperature ranges are required, or when integrated accessory packages are preferred for assembly efficiency.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UTS718-32S is determined by strict alignment of the following parameters:

Critical Parameters (Must Match Exactly):

• Number of Positions: 32
• Shell Size - Insert: 18-32
• Contact Type: Crimp
• Contact Size: 20
• Mounting Type: Panel Mount
• Mounting Feature: Bulkhead - Front Side Nut
• Fastening Type: Bayonet Lock
• Ingress Protection: IP67/IP69K
• Shell Material: Thermoplastic
• Housing Color: Black
• Flammability Rating: UL94 V-0

Allowable Variations:

• Operating Temperature Range: Extended ranges are acceptable if the minimum (-40°C) and maximum (105°C) requirements of the original application are met or exceeded
• Included Accessories: Substitute parts may include additional components (gaskets, nuts, O-rings) without affecting substitution eligibility
• Insert Material: Thermoplastic composition is acceptable
• Moisture Sensitivity Level: Variations are acceptable

The RTS718N32S03 meets all critical parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the UTS718-32S and RTS718N32S03 are active production components with full regulatory compliance. Selection between these parts should be based on the following criteria:

UTS718-32S (Souriau-Sunbank by Eaton):

• Select when the Trim Trio® UTS series is specified in system documentation
• Operating temperature applications within -40°C to 105°C range
• When contacts are sourced separately

RTS718N32S03 (Amphenol Sine Systems Corp):

• Select when the ecomate® Aquarius™ series is specified in system documentation
• Operating temperature applications requiring extended range up to 125°C
• When integrated accessory packages (gasket, nut, O-ring) reduce assembly steps
• When higher inventory availability is advantageous for procurement

Both parts carry ROHS3 compliance and REACH Unaffected status, confirming regulatory alignment for current manufacturing standards. The RTS718N32S03 provides extended thermal operating range, which accommodates applications with higher temperature exposure without requiring design modification.

Frequently Asked Questions (FAQ)

Q: Can RTS718N32S03 be used as a direct replacement for UTS718-32S in all applications?

A: Yes, the RTS718N32S03 qualifies as a direct substitute. Both parts share identical critical specifications: 32 positions, shell size 18-32, crimp contact type, size 20, panel mount configuration, bayonet lock fastening, and IP67/IP69K protection. The RTS718N32S03 provides extended operating temperature range (-40°C to 125°C versus -40°C to 105°C), which is compatible with or exceeds the original part's thermal requirements.

Q: What is the difference in included components between these two parts?

A: The UTS718-32S is supplied without contacts or accessories. The RTS718N32S03 includes four components: one connector, one gasket, one nut, and one O-ring. These accessories support assembly efficiency but do not affect electrical or mechanical compatibility.

Q: Are there any compatibility issues with existing connector inserts or mating plugs?

A: No compatibility issues exist. Both receptacle housings share identical shell size (18-32), position count (32), and contact specifications (crimp, size 20). Existing mating plugs and contact inserts designed for UTS718-32S are fully compatible with RTS718N32S03.

Q: Which part should be selected for high-temperature applications?

A: The RTS718N32S03 is suitable for applications requiring operation up to 125°C. The UTS718-32S is rated to 105°C. For applications exceeding 105°C, the RTS718N32S03 is the appropriate selection.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the UTS718-32S and RTS718N32S03 are ROHS3 compliant and REACH Unaffected, confirming compliance with current environmental and hazardous substance regulations.

Q: What is the significance of the bayonet lock fastening type?

A: Bayonet lock fastening provides quick-connect and quick-disconnect capability with positive engagement. Both parts employ identical bayonet lock mechanisms, ensuring interchangeable mating performance and field serviceability.
