MU14-110DFX Equivalent & Substitute Parts

Part Overview

The MU14-110DFX is a 0.110" (2.79mm) Quick Connect Female crimp connector manufactured by 3M under the Scotchlok™ series. Designed for 14-16 AWG wire applications, this non-insulated terminal features a butted seam construction with tin-plated brass contacts. The product is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing maintenance and repair applications where this connector type is specified in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MU14-110DFX is determined by strict alignment of the following critical parameters:

Primary Compatibility Criteria:

• Tab width: 0.110" (2.79mm) minimum requirement
• Tab thickness: 0.020" (0.51mm)
• Gender: Female
• Termination method: Crimp
• Contact material: Brass with tin finish
• Insulation type: Non-insulated
• Mounting configuration: Free hanging (in-line)

The identified substitute, TE Connectivity AMP Connectors part number 62852-1, maintains these core mechanical and electrical parameters. The wire gauge range extends from 14-16 AWG to 14-18 AWG, providing broader applicability while preserving compatibility with the original 14-16 AWG specification. Both connectors feature identical tab thickness and contact material specifications, ensuring mechanical interchangeability in the mating interface.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 62852-1 (Faston series) is the designated substitute for the obsolete MU14-110DFX. Selection is based on the following engineering factors:

Product Status: The MU14-110DFX is obsolete and no longer manufactured. The 62852-1 is in active production status, ensuring long-term availability and supply chain continuity.

Regulatory Compliance: Both connectors maintain identical REACH Unaffected status and MSL rating of 1 (Unlimited), confirming equivalent environmental and moisture handling characteristics.

Mechanical Compatibility: Critical dimensions—tab width (0.110"), tab thickness (0.020"), and overall mounting configuration—are identical or compatible. The 0.065" difference in overall length (0.540" versus 0.475") represents a minor dimensional variation that does not affect mating interface performance.

Electrical Equivalence: Contact material (brass), finish (tin), and termination method (crimp) are identical, ensuring equivalent electrical performance and connection reliability.

Wire Gauge Consideration: The 62852-1 accommodates 14-18 AWG wire, extending the original 14-16 AWG range. Applications using 14-16 AWG wire remain fully compatible.

Frequently Asked Questions (FAQ)

Q: Can the 62852-1 directly replace the MU14-110DFX in existing assemblies?

A: Yes. The 62852-1 maintains identical tab width (0.110"), tab thickness (0.020"), gender (female), and mounting configuration (free hanging in-line). These parameters determine mating interface compatibility. The minor difference in overall length does not affect connector function.

Q: What is the significance of the extended wire gauge range (14-18 AWG) in the 62852-1?

A: The 62852-1 accommodates a broader wire gauge range than the original MU14-110DFX (14-16 AWG). Applications using 14-16 AWG wire remain fully compatible. The extended range provides flexibility for future designs but does not alter compatibility with existing 14-16 AWG applications.

Q: Are there any compliance or regulatory differences between these connectors?

A: No. Both connectors share identical REACH Unaffected status, MSL rating of 1 (Unlimited), and ECCN classification (EAR99). Regulatory compliance is equivalent.

Q: What is the packaging difference between these parts?

A: The MU14-110DFX is listed with no specified packaging format. The 62852-1 is supplied in Cut Tape (CT) packaging. Verify packaging requirements for your procurement process.

Q: Why is the 62852-1 considered the manufacturer-recommended substitute?

A: The 62852-1 is identified as the MFR (Manufacturer) Recommended substitute based on strict alignment of all critical electrical and mechanical parameters: tab dimensions, contact material, finish, termination method, and mounting configuration. The substitute is in active production, addressing the obsolescence of the original part.
