TE Connectivity AMP Connectors 346103-2 Ring Terminal Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 346103-2 is a ring terminal connector designed for circular applications with 14-17 AWG wire gauge capacity. This non-insulated copper alloy terminal is configured for crimp termination and free-hanging in-line mounting. The part is currently active in production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when specific contact finish requirements differ.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 346103-4 is classified as a direct equivalent based on the following matching parameters:

Matching Electrical and Mechanical Specifications:

• Terminal Type: Circular
• Wire Gauge: 14-17 AWG
• Termination Method: Crimp
• Mounting Type: Free Hanging (In-Line)
• Insulation: Non-Insulated
• Contact Material: Copper Alloy
• Width - Outer Edges: 0.472" (12.00mm)
• Insulation Diameter: 0.087" ~ 0.118" (2.21mm ~ 3.00mm)
• Packaging: Tape & Reel (TR)
• RoHS Status: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

Distinguishing Parameter:

• Contact Finish: 346103-4 includes Tin finish, while 346103-2 does not specify a contact finish

Both parts share the same base product number (346103) and are manufactured by TE Connectivity AMP Connectors. The substitution is valid where contact finish specifications permit tin-plated copper alloy terminals.

Parameter Comparison

Engineering Selection Recommendations

Both 346103-2 and 346103-4 are active production parts manufactured by TE Connectivity AMP Connectors and maintain full ROHS3 compliance with unlimited moisture sensitivity tolerance. Selection between these parts is determined by contact finish requirements:

346103-2 Selection Criteria:

• Applications where unspecified or bare copper alloy contact finish is acceptable
• Designs without explicit tin-plated terminal requirements

346103-4 Selection Criteria:

• Applications requiring tin-plated contact finish for enhanced corrosion resistance
• Designs specifying tin-finished copper alloy terminals
• Environments where contact finish specification is a design requirement

Both parts are supplied in Tape & Reel packaging and are suitable for automated assembly processes. The electrical and mechanical compatibility between these parts is complete across all specified parameters except contact finish.

Frequently Asked Questions (FAQ)

Q: Can 346103-4 be used as a direct replacement for 346103-2?

A: Yes, 346103-4 is a direct substitute for 346103-2 when tin-plated contact finish is acceptable or required by design specifications. All electrical and mechanical parameters are identical, with the only difference being the tin contact finish on 346103-4.

Q: What is the significance of the contact finish difference?

A: The tin finish on 346103-4 provides enhanced corrosion resistance compared to unfinished copper alloy. Selection depends on application environment and design requirements. Both finishes are compatible with 14-17 AWG crimp termination.

Q: Are both parts available in the same packaging format?

A: Yes, both 346103-2 and 346103-4 are supplied in Tape & Reel (TR) packaging, suitable for automated assembly and component handling.

Q: Do these parts have different compliance certifications?

A: No, both parts maintain identical compliance status: ROHS3 compliant, MSL 1 (Unlimited), ECCN EAR99, and HTSUS 8536.90.4000.

Q: What wire gauges are supported by these terminals?

A: Both parts support 14-17 AWG wire gauge with insulation diameter range of 0.087" to 0.118" (2.21mm to 3.00mm).

Q: Are these parts suitable for automated assembly?

A: Yes, both parts are supplied in Tape & Reel packaging format, which is standard for automated pick-and-place assembly processes.

Q: What is the mounting configuration for these terminals?

A: Both parts are configured as free-hanging in-line terminals, designed for direct crimp attachment to wire without additional mounting hardware.
