Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 13-56S is determined by strict equivalence across the following critical parameters:

• Terminal Type: Must be circular ring terminal
• Wire Gauge Compatibility: Must accommodate 10-12 AWG wire
• Stud Size: Must be 5/16 inch stud connection
• Termination Method: Must be crimp-type termination
• Insulation Classification: Must be non-insulated
• Contact Material: Must be copper-based
• Contact Finish: Must be tin-plated
• Mounting Configuration: Must be free-hanging in-line style
• Regulatory Compliance: Must maintain ROHS3 compliance

The Panduit Corp P10-56R-L meets all substitution criteria within the mechanical tolerance ranges specified for this product category.

Parameter Comparison

Engineering Selection Recommendations

Both the 3M 13-56S and Panduit P10-56R-L ring terminal connectors are active production parts with ROHS3 compliance certification. Selection between these parts may be based on inventory availability, supply chain considerations, or established procurement specifications. The 3M 13-56S features butted seam construction, while the Panduit P10-56R-L incorporates brazed seam and serrated termination design. Both designs are functionally equivalent for 10-12 AWG crimp termination applications with 5/16 inch stud connections. Mechanical dimensions remain within standard tolerance ranges for this terminal category, with width and length variations of less than 1% between manufacturers.

Frequently Asked Questions (FAQ)

Q: Can the Panduit P10-56R-L be used as a direct replacement for the 3M 13-56S?

A: Yes. Both parts meet identical electrical and mechanical specifications for 10-12 AWG wire gauge, 5/16 inch stud connection, crimp termination, and non-insulated circular ring terminal configuration. Dimensional variations fall within acceptable tolerance ranges for this product category.

Q: What is the difference between butted seam and brazed seam construction?

A: Butted seam construction (3M 13-56S) and brazed seam construction (Panduit P10-56R-L) represent different manufacturing methods for joining terminal components. Both methods produce functionally equivalent electrical and mechanical performance for this application class.

Q: Are both parts RoHS compliant?

A: Yes. Both the 3M 13-56S and Panduit P10-56R-L are ROHS3 compliant and suitable for applications requiring RoHS certification.

Q: What wire gauges are compatible with these terminals?

A: Both terminals are designed for 10-12 AWG wire gauges. Wire gauge compatibility is a critical substitution parameter and cannot be altered without changing the part classification.

Q: Do these terminals require insulation?

A: No. Both parts are non-insulated ring terminals. If insulation is required for your application, these parts are not suitable and an insulated terminal variant must be specified.

Q: What is the stud size for these connectors?

A: Both terminals feature a 5/16 inch stud connection. Stud size is a fixed specification and determines compatibility with mating hardware.
