MH10-38RK Equivalent & Substitute Parts

Part Overview

The MH10-38RK is a ring terminal connector manufactured by 3M, designed for 10-12 AWG wire gauges with a 3/8 inch stud connection. This insulated circular terminal features a brazed seam construction and tin-plated copper contact material. The product is active and widely used in electrical assembly applications requiring reliable crimped connections. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory availability, supply chain considerations, or application-specific requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MH10-38RK 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 3/8 Stud
• Termination Method: Must be Crimp
• Insulation Type: Must be Insulated with Heat Shrink
• Contact Material: Must be Copper
• Contact Finish: Must be Tin
• Overall Dimensions: Length 1.200" (30.48mm) and Width 0.590" (14.99mm)
• Mounting Type: Must be Free Hanging (In-Line)
• Insulation Material: Must be Polyolefin

The substitute part PH10-38R-E meets all critical electrical and mechanical parameters required for direct substitution in applications currently using the MH10-38RK.

Parameter Comparison

Engineering Selection Recommendations

Both the MH10-38RK and PH10-38R-E are active products with full regulatory compliance. The MH10-38RK carries RoHS Compliant certification, while the PH10-38R-E carries ROHS3 Compliant certification. Both products maintain REACH Unaffected status and share identical ECCN and HTSUS classifications. Selection between these parts should be based on availability, lead time, and existing supply chain relationships, as all critical electrical and mechanical parameters are equivalent.

Frequently Asked Questions (FAQ)

Q: Can PH10-38R-E be used as a direct replacement for MH10-38RK?

A: Yes. The PH10-38R-E meets all critical electrical and mechanical specifications required for direct substitution, including wire gauge (10-12 AWG), stud size (3/8 inch), terminal type (circular), termination method (crimp), insulation type (heat shrink polyolefin), contact material (copper with tin finish), and overall dimensions (1.200" × 0.590").

Q: Are there any dimensional differences between these parts?

A: No. Both parts share identical overall length (1.200" / 30.48mm) and width (0.590" / 14.99mm) specifications. The MH10-38RK specifies a thickness of 0.040" (1.02mm), while the PH10-38R-E does not provide this specification in available documentation. Both parts feature brazed seam construction.

Q: Do both parts meet current regulatory requirements?

A: Yes. The MH10-38RK is RoHS Compliant, and the PH10-38R-E is ROHS3 Compliant. Both maintain REACH Unaffected status and share identical export classification (EAR99) and tariff codes (8536.90.4000).

Q: What wire gauges are supported by these terminals?

A: Both terminals are rated for 10-12 AWG wire gauges. This specification is identical across both parts.

Q: Are these terminals suitable for the same stud sizes?

A: Yes. Both the MH10-38RK and PH10-38R-E are designed for 3/8 inch stud connections and are mechanically compatible with identical mounting configurations.
