Key Parameters

Substitute Part Grouping Explanation

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

• Terminal Type: Must be Circular
• Wire Gauge: Must be 10-12 AWG
• Stud/Tab Size: Must be 5/16 Stud
• Termination Method: Must be Crimp
• Insulation Type: Must be Non-Insulated
• Contact Material: Must be Copper
• Contact Finish: Must be Tin
• Mounting Type: Must be Free Hanging (In-Line)
• RoHS Compliance: Must be ROHS3 Compliant

The Panduit Corp P10-56R-L meets all substitution criteria and is classified as a manufacturer-recommended equivalent part.

Parameter Comparison

Engineering Selection Recommendations

• Availability: Panduit P10-56R-L has 2181 pieces in inventory compared to 791 pieces for the 3M 13-56-W
• Series Designation: Panduit part is designated as Pan-Term® series
• Additional Features: Panduit P10-56R-L includes serrated termination feature
• Regulatory Status: Panduit part includes REACH Unaffected designation

Both parts satisfy ECCN EAR99 classification and HTSUS code 8536.90.4000 requirements.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical wire gauge (10-12 AWG), stud size (5/16), termination method (crimp), contact material (copper with tin finish), and mounting configuration. Both are ROHS3 compliant and active production parts.

Q: What is the significance of the serrated termination feature on the Panduit part?

A: The serrated termination on the Panduit P10-56R-L is an additional feature that does not affect substitution eligibility. Both parts maintain equivalent electrical and mechanical performance for the specified wire gauge and stud size.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist. The 3M 13-56-W has a width of 0.590" (14.99mm) and length of 0.990" (25.15mm), while the Panduit P10-56R-L measures 0.520" (13.21mm) width and 0.950" (24.13mm) length. Both maintain the same 0.040" (1.02mm) thickness. These variations do not affect functional compatibility for the specified application.

Q: What packaging is available for both parts?

A: Both the 3M 13-56-W and Panduit P10-56R-L are supplied in bulk packaging.

Q: Are there any compliance or regulatory differences?

A: Both parts are ROHS3 compliant and classified as EAR99 for export control purposes. The Panduit part includes REACH Unaffected status. The 3M part has MSL rating of 1 (Unlimited), while the Panduit part lists MSL as Not Applicable.
