MN14CEC/STK Equivalent & Substitute Parts Reference

Part Overview

The 3M MN14CEC/STK is a terminal butt splice connector designed for crimp termination of 14-22 AWG copper wire. This fully insulated, closed-end, single-opening splice terminal is part of the Scotchlok™ series. 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

Substitute parts for the MN14CEC/STK are qualified based on strict equivalence across the following critical parameters:

• Terminal Type: Butt Splice, Closed End, Single Opening
• Wire Gauge Range: 14-22 AWG
• Termination Method: Crimp
• Insulation: Fully Insulated
• Moisture Sensitivity Level: 1 (Unlimited)
• Electrical Classification: ECCN EAR99, HTSUS 8536.90.4000

All four substitute parts listed below meet these criteria and are currently in active production status, providing long-term availability for replacement applications.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are functionally equivalent to the obsolete MN14CEC/STK based on terminal type, wire gauge, termination method, and insulation specifications.

Molex 0191600012: Active product status with ROHS3 compliance and REACH Unaffected certification. Highest inventory availability (489,949 pcs). Suitable for applications requiring maximum supply chain continuity.

TE Connectivity 1-35115-0: Active product status with ROHS3 compliance. Lower inventory availability (1,162 pcs) compared to Molex. REACH status listed as Vendor Undefined; clarification recommended for applications with strict REACH requirements.

Panduit JN218-216-C and JN218-216-M: Both active products with ROHS3 compliance and REACH Unaffected certification. Part of the Pan-Term® series. MSL listed as Not Applicable. JN218-216-M offers significantly higher inventory (21,662 pcs) compared to JN218-216-C (3,450 pcs). Both are suitable for applications requiring REACH compliance assurance.

Selection should prioritize product availability, supply chain requirements, and regulatory compliance status for the intended application.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0191600012 be used as a direct replacement for the 3M MN14CEC/STK?

A: Yes. Both terminals are butt splice, closed-end, single-opening connectors rated for 14-22 AWG crimp termination with full insulation. Electrical and mechanical parameters are equivalent.

Q: What is the difference between the two Panduit substitute parts (JN218-216-C and JN218-216-M)?

A: Both JN218-216-C and JN218-216-M are functionally identical butt splice terminals with identical electrical and mechanical specifications. The primary difference is packaging and inventory availability. JN218-216-M has significantly higher stock levels (21,662 pcs vs. 3,450 pcs).

Q: Are all substitute parts RoHS compliant?

A: Yes. All four substitute parts carry ROHS3 Compliant certification, meeting current environmental and hazardous substance restrictions.

Q: Does the TE Connectivity 1-35115-0 have REACH compliance documentation?

A: The TE Connectivity part lists REACH status as Vendor Undefined. For applications requiring confirmed REACH compliance, the Molex or Panduit alternatives with REACH Unaffected certification are recommended.

Q: What packaging formats are available for these substitute parts?

A: Molex 0191600012 is supplied in Bulk packaging. TE Connectivity 1-35115-0 is supplied in Cut Tape (CT). Both Panduit parts (JN218-216-C and JN218-216-M) are supplied in Bulk packaging. Packaging selection should align with assembly process requirements.

Q: Are these terminals suitable for copper wire only?

A: The original 3M MN14CEC/STK specifies copper wire only. All substitute parts are designed for standard copper wire termination within the 14-22 AWG range. Compatibility with other conductor materials should be confirmed with the respective manufacturer if required.
