S2-10R-X Ring Terminal Connector Equivalent & Substitute Parts

Part Overview

The S2-10R-X is a ring terminal connector manufactured by Panduit Corp, classified as a flat-sided ring terminal designed for 1-2 AWG wire gauges with a #10 stud connection. This non-insulated copper terminal features a tin finish and funnel opening for crimp termination. The part is currently obsolete, necessitating identification of equivalent substitute components that maintain identical electrical and mechanical specifications for continued application support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the S2-10R-X is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Wire gauge range: 1-2 AWG
• Stud size: #10
• Contact material: Copper
• Contact finish: Tin
• Termination method: Crimp with funnel opening

Mechanical Compatibility Parameters:

• Terminal type: Flat sided
• Overall dimensions: 1.600" length × 0.700" width × 0.110" thickness
• Mounting configuration: Free hanging (in-line)
• Insulation status: Non-insulated

Regulatory Compliance Parameters:

• RoHS3 compliance
• REACH unaffected status
• ECCN: EAR99
• HTSUS: 8536.90.4000

The substitute part S2-10R-T maintains identical specifications across all electrical, mechanical, and regulatory parameters, establishing direct substitutability.

Parameter Comparison

Engineering Selection Recommendations

Both the S2-10R-X and S2-10R-T are classified as obsolete products. Selection between these parts is based on current inventory availability and application requirements.

S2-10R-X (Pan-Term® Series): 907 pieces in stock. This part maintains full compliance with ROHS3 and REACH requirements. Electrical and mechanical specifications are suitable for 1-2 AWG wire termination on #10 studs in non-insulated applications.

S2-10R-T (Pan-Lug™ Series): 746 pieces in stock. This part is functionally equivalent to the S2-10R-X, with identical electrical, mechanical, and regulatory compliance characteristics. The primary distinction is series designation (Pan-Lug™ versus Pan-Term®), which does not affect terminal performance or compatibility.

Both parts are suitable for direct substitution in applications requiring flat-sided ring terminals with crimp funnel opening termination for 1-2 AWG conductors on #10 stud connections. Selection should be based on inventory availability and application-specific requirements.

Frequently Asked Questions (FAQ)

Q: Can S2-10R-T be used as a direct replacement for S2-10R-X?

A: Yes. The S2-10R-T is a direct substitute for the S2-10R-X. All electrical parameters (wire gauge, stud size, contact material, contact finish, termination method), mechanical dimensions (length, width, thickness), and regulatory compliance specifications are identical between the two parts.

Q: What is the difference between the Pan-Term® and Pan-Lug™ series designations?

A: The series designation indicates the product line classification within Panduit Corp's terminal portfolio. For the S2-10R-X and S2-10R-T, this distinction does not affect electrical performance, mechanical compatibility, or regulatory compliance. Both series employ identical specifications for this ring terminal connector.

Q: Are both parts suitable for the same wire gauge applications?

A: Yes. Both the S2-10R-X and S2-10R-T are rated for 1-2 AWG wire gauges and feature identical crimp funnel opening termination. They are interchangeable for applications within this wire gauge range.

Q: What does "flat sided" terminal type mean?

A: Flat sided refers to the terminal geometry, where the ring opening features flat parallel sides rather than a circular or oval profile. This design provides specific mechanical and electrical characteristics for stud connection applications.

Q: Are these terminals insulated?

A: No. Both the S2-10R-X and S2-10R-T are non-insulated terminals. The copper conductor is exposed and finished with tin plating. Insulation must be provided through external means if required by the application.

Q: What is the significance of the #10 stud size?

A: The #10 stud size refers to the diameter of the connection point on the terminal. This dimension determines mechanical fit and electrical contact with corresponding #10 stud or bolt connections. Both substitute parts are designed for #10 stud applications.

Q: Do these parts meet current environmental compliance standards?

A: Yes. Both the S2-10R-X and S2-10R-T are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: What is the funnel opening termination feature?

A: The funnel opening is a tapered entry design at the wire insertion point of the terminal. This feature facilitates easier wire insertion during the crimp termination process and helps ensure proper conductor seating within the terminal barrel.
