MU14-6FB/SK Equivalent & Substitute Parts

Part Overview

The MU14-6FB/SK is a 6 stud spade terminal connector manufactured by 3M under the Scotchlok™ series. This non-insulated crimp terminal is designed for 14-16 AWG wire applications with a tin-plated copper contact and butted seam construction. The part is currently active in production with RoHS compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent parts are identified when component availability, packaging formats, or supply chain requirements necessitate alternative sourcing while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MU14-6FB/SK is determined by strict alignment of the following critical parameters:

• Wire gauge range (14-16 AWG)
• Stud size (6 stud configuration)
• Termination method (crimp)
• Contact material (copper)
• Contact finish (tin plating)
• Insulation status (non-insulated)
• Mounting configuration (free hanging, in-line)

The substitute part 2-322996-1 (TE Connectivity AMP Connectors, Solistrand series) meets all core electrical and mechanical requirements. Both parts are active products with current RoHS compliance certifications, ensuring regulatory alignment for new designs and production environments.

Parameter Comparison

Engineering Selection Recommendations

Both the MU14-6FB/SK and 2-322996-1 are active production components with current regulatory compliance. The MU14-6FB/SK features butted seam construction, while the substitute 2-322996-1 incorporates brazed seam and serrated termination design. Both maintain identical wire gauge compatibility (14-16 AWG), stud configuration (6 stud), and contact specifications (copper with tin finish).

Selection between these parts should be based on packaging requirements (bulk versus cut tape format), seam construction preference, and supply chain availability. Both parts satisfy RoHS compliance requirements and carry unlimited moisture sensitivity ratings, making them suitable for equivalent circuit applications.

Frequently Asked Questions (FAQ)

Q: Can 2-322996-1 directly replace MU14-6FB/SK in existing assemblies?

A: Yes. Both parts meet the core electrical and mechanical specifications: 14-16 AWG wire gauge, 6 stud configuration, crimp termination, copper contact with tin finish, and non-insulated design. The primary differences are seam construction (butted versus brazed) and packaging format (bulk versus cut tape).

Q: What is the difference between butted seam and brazed seam construction?

A: Butted seam (MU14-6FB/SK) and brazed seam (2-322996-1) represent different manufacturing approaches to terminal construction. Both are acceptable for 14-16 AWG crimp applications. Brazed seam construction in the substitute part includes serrated termination features.

Q: Are there packaging considerations when switching between these parts?

A: Yes. The MU14-6FB/SK is supplied in bulk packaging, while 2-322996-1 is supplied in cut tape (CT) format. Bulk packaging is suitable for manual assembly or loose component handling, while cut tape format is optimized for automated pick-and-place equipment and tape-fed assembly processes.

Q: Do both parts meet current RoHS requirements?

A: Yes. The MU14-6FB/SK is RoHS Compliant, and 2-322996-1 is ROHS3 Compliant. Both meet current regulatory standards for new product designs and manufacturing environments.

Q: What is the MSL rating for these terminals?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.
