TE Connectivity AMP Connectors 346100-3 Ring Terminal Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 346100-3 is a non-insulated ring terminal connector designed for circular crimp termination applications. This component is classified as a free-hanging, in-line terminal suitable for wire gauges 17-20 AWG. The part is currently active in production status with RoHS compliance and unlimited moisture sensitivity rating (MSL 1). Alternative equivalent parts are necessary to support supply chain flexibility, inventory management, and application-specific contact finish requirements while maintaining identical electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 346100-3 ring terminal connector is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Terminal Type: Circular
• Wire Gauge: 17-20 AWG
• Termination Method: Crimp
• Mounting Type: Free Hanging (In-Line)
• Insulation Classification: Non-Insulated
• Width - Outer Edges: 0.374" (9.50mm)
• Insulation Diameter: 0.055" ~ 0.083" (1.40mm ~ 2.11mm)
• Contact Material: Copper Alloy
• RoHS Status: RoHS Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Variable Parameters Permitting Substitution:

• Contact Finish: Variations in contact finish (such as tin plating) do not affect mechanical or electrical compatibility when all other parameters remain constant.

The substitute part 346100-4 maintains complete equivalence across all mandatory parameters while introducing a tin contact finish specification. This variation represents a direct functional equivalent suitable for identical applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 346100-3 and 346100-4 ring terminal connectors are active production components with RoHS compliance and unlimited moisture sensitivity ratings. Selection between these parts is based on the following engineering criteria:

346100-3 Selection Criteria:

• Applications where contact finish is not specified or where unfinished copper alloy contacts are acceptable
• Designs requiring maximum cost efficiency without finish-specific requirements
• Inventory availability: 1018 pieces in stock

346100-4 Selection Criteria:

• Applications requiring tin-plated contact finish for enhanced corrosion resistance
• Designs where contact finish specification is explicitly required
• Inventory availability: 902 pieces in stock

Both parts maintain identical mechanical dimensions, electrical properties, and compliance certifications. The substitution is direct and interchangeable across all functional parameters. Selection should be based on application-specific contact finish requirements and current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can 346100-4 be used as a direct replacement for 346100-3?

A: Yes. The 346100-4 is a direct functional equivalent to the 346100-3. Both parts share identical terminal type, wire gauge rating, crimp termination method, mounting configuration, and dimensional specifications. The only difference is the tin contact finish on the 346100-4, which does not affect mechanical or electrical compatibility.

Q: What is the difference between the 346100-3 and 346100-4?

A: The primary difference is the contact finish. The 346100-3 features unspecified contact material finish, while the 346100-4 includes a tin contact finish. All other electrical and mechanical parameters are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both the 346100-3 and 346100-4 are RoHS compliant and carry an unlimited moisture sensitivity level (MSL 1).

Q: What wire gauges are supported by these ring terminals?

A: Both parts support wire gauges from 17 AWG to 20 AWG.

Q: Can these non-insulated ring terminals be used in high-vibration applications?

A: Compatibility with high-vibration applications is determined by the mounting method (free-hanging, in-line) and the mechanical design of the assembly. The terminal specifications provided do not include vibration rating data.

Q: What is the insulation diameter range for these terminals?

A: The insulation diameter range is 0.055" to 0.083" (1.40mm to 2.11mm) for both parts.

Q: Are these terminals suitable for outdoor applications?

A: Both parts are non-insulated copper alloy terminals. Suitability for outdoor applications depends on the overall assembly design, environmental protection measures, and the specific application requirements beyond the terminal specifications provided.

Q: What is the outer edge width of these ring terminals?

A: The outer edge width is 0.374" (9.50mm) for both the 346100-3 and 346100-4.
