M14-6FLK Equivalent & Substitute Parts

Part Overview

The M14-6FLK is a 6 stud spade terminal connector manufactured by 3M, designed for crimp termination of 14-16 AWG wire. This non-insulated terminal operates as a spring snap connector for free-hanging in-line applications. The part is Active in product status and RoHS Compliant, making it suitable for current procurement and deployment in compliant assemblies. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part is unavailable or when alternative packaging or inventory conditions warrant evaluation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M14-6FLK is determined by strict alignment of the following parameters:

• Wire gauge range (14-16 AWG)
• Stud size (6 stud configuration)
• Terminal type (spring snap connector)
• Crimp termination capability
• Non-insulated construction
• Free-hanging in-line mounting
• Tin contact finish
• RoHS compliance status

The substitute part 53123-2 (TE Connectivity AMP Connectors, Solistrand series) meets all primary electrical and mechanical requirements. Dimensional variations in overall length and termination length do not affect functional compatibility within the specified wire gauge and stud size parameters. The addition of serrated termination on the substitute part provides enhanced mechanical retention without altering the crimp interface or electrical performance.

Parameter Comparison

Engineering Selection Recommendations

Both the M14-6FLK and 53123-2 are Active products with RoHS Compliance and EAR99 ECCN classification, confirming current manufacturability and regulatory alignment. Selection between these parts should be based on:

• Packaging requirements: M14-6FLK is supplied in Bulk; 53123-2 is supplied in Cut Tape (CT)
• Inventory availability: 53123-2 has higher stock levels (15,353 pcs vs. 944 pcs)
• Contact material preference: M14-6FLK uses Copper ETP; 53123-2 uses Phosphor Bronze
• Dimensional tolerance: Overall length differs by 0.104" (2.64mm); ring center to termination remains identical

Both parts satisfy the core electrical and mechanical requirements for 14-16 AWG crimp termination on 6 stud connectors. The serrated termination feature on 53123-2 provides additional mechanical retention without affecting compatibility with standard crimp tooling or stud interfaces.

Frequently Asked Questions (FAQ)

Q: Can 53123-2 be used as a direct replacement for M14-6FLK?

A: Yes. Both parts meet the specified wire gauge (14-16 AWG), stud size (6 stud), terminal type (spring snap), and termination method (crimp). The electrical and mechanical interfaces are compatible.

Q: What is the significance of the overall length difference between these parts?

A: The overall length difference (0.680" vs. 0.576") reflects design variations between manufacturers. The critical dimension—length from ring center to termination (0.250" for both)—remains identical, ensuring proper stud engagement and crimp interface alignment.

Q: Does the contact material difference affect performance?

A: Both Copper ETP and Phosphor Bronze are acceptable contact materials for tin-plated spade terminals in this application class. Material selection does not alter electrical conductivity or compatibility within the specified wire gauge range.

Q: What is the impact of serrated termination on 53123-2?

A: Serrated termination enhances mechanical retention of the crimp connection without affecting the crimp interface or requiring different tooling. This feature is compatible with standard spade terminal crimping equipment.

Q: Are packaging differences significant for substitution?

A: Packaging format (Bulk vs. Cut Tape) affects handling, storage, and assembly line integration but does not impact electrical or mechanical compatibility. Selection depends on manufacturing process requirements and inventory management practices.

Q: Do both parts meet compliance requirements?

A: Yes. Both M14-6FLK and 53123-2 are RoHS Compliant with EAR99 ECCN classification and MSL 1 (Unlimited) moisture sensitivity rating, confirming suitability for regulated applications.
