MN10CEC/STK Equivalent & Substitute Parts

Part Overview

The 3M MN10CEC/STK is a terminal butt splice connector designed for crimp termination of 10-18 AWG copper wire. This closed-end, single-opening connector provides fully insulated splice connections. The product is currently obsolete, making equivalent substitute parts necessary for ongoing maintenance and repair applications where this connector type is specified in existing designs or systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MN10CEC/STK is determined by the following critical parameters:

Primary Compatibility Criteria:

• Terminal type: Butt splice, closed end, single opening
• Termination method: Crimp
• Insulation: Fully insulated
• Wire material: Copper wire
• Number of wire entries: Single opening

Wire Gauge Overlap: The original part covers 10-18 AWG. Substitute parts must accommodate wire gauges within or overlapping this range. Partial overlap is acceptable where the substitute covers the upper or lower portion of the original range, provided the terminal type and termination method remain identical.

Compliance Baseline: All substitute parts maintain REACH Unaffected status and EAR99 ECCN classification, consistent with the original part.

The three identified substitutes meet these criteria with the following wire gauge coverage:

• 0191600002 (Molex): 10-16 AWG (partial overlap, lower range)
• JN418-212-C (Panduit): 12-18 AWG (partial overlap, upper range)
• JN418-212-D (Panduit): 12-18 AWG (partial overlap, upper range)

Parameter Comparison

Engineering Selection Recommendations

For 10-16 AWG applications: The Molex 0191600002 provides direct substitution for wire gauges 10-16 AWG and maintains the same MSL rating as the original part. This part is currently in active production status with substantial inventory availability (29,147 pcs).

For 12-18 AWG applications: Both Panduit Pan-Term® options (JN418-212-C and JN418-212-D) are suitable for wire gauges 12-18 AWG. Both parts are active production items with RoHS3 compliance. JN418-212-D has higher inventory availability (5,198 pcs vs. 1,632 pcs for JN418-212-C).

For full 10-18 AWG coverage: No single substitute part covers the complete original wire gauge range. Applications requiring 10-11 AWG termination must use the Molex 0191600002. Applications requiring 12-18 AWG termination may use either Panduit option. Mixed-gauge applications may require multiple part numbers.

All substitute parts are RoHS3 compliant and maintain REACH Unaffected status, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0191600002 replace the 3M MN10CEC/STK in all applications? A: The Molex part covers 10-16 AWG, which does not include the 17-18 AWG range of the original part. It is suitable only for applications using wire gauges 10-16 AWG.

Q: Can the Panduit JN418-212-C or JN418-212-D replace the 3M MN10CEC/STK in all applications? A: The Panduit parts cover 12-18 AWG, which does not include the 10-11 AWG range of the original part. They are suitable only for applications using wire gauges 12-18 AWG.

Q: What is the difference between JN418-212-C and JN418-212-D? A: Both parts are identical in electrical and mechanical specifications. The difference is inventory availability, with JN418-212-D having higher stock levels.

Q: Are all substitute parts fully interchangeable with the original MN10CEC/STK? A: No. Substitution is limited by wire gauge overlap. The original part's 10-18 AWG range is not fully covered by any single substitute. Selection depends on the specific wire gauge requirements of the application.

Q: Do the substitute parts meet the same compliance standards as the original? A: All substitute parts maintain REACH Unaffected status and EAR99 ECCN classification. The Molex and Panduit parts are RoHS3 compliant, exceeding the original part's compliance profile.

Q: What is the significance of "Number of Wire Entries: Varies by Wire Size" for the Molex part? A: This indicates that the terminal design accommodates different wire gauges within its range (10-16 AWG) with appropriate sizing for each gauge. This is functionally equivalent to the single-opening design of the original part.
