TE Connectivity AMP Connectors 4-1546701-6 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 4-1546701-6 is an 8-circuit barrier block connector with 0.375" (9.53mm) pitch spacing, designed for chassis and panel mounting applications. This terminal block features screw-based top termination and solder turret bottom termination with dual-wall barrier construction. The part is currently active in production and widely used in industrial control, power distribution, and signal routing applications where reliable multi-circuit connections are required.

Substitute parts become necessary when the primary part experiences extended lead times, inventory constraints, or when design requirements permit alternative manufacturers that meet identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity AMP Connectors 4-1546701-6 are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic requires that alternative parts maintain identical specifications in the following areas:

Critical Matching Parameters:

• 8-circuit configuration with 0.375" (9.53mm) pitch spacing
• 20A current rating and 300V voltage rating
• 12-22 AWG wire gauge acceptance
• Barrier block terminal type with dual-wall (2 Wall) barrier construction
• Screw-based top termination and solder turret insulated bottom termination
• Chassis and panel mounting capability

Compliance Parameters:

• UL94 V-0 flammability rating
• RoHS compliance status
• Thermoplastic insulation material

Parts that deviate from any critical parameter are not considered substitutes and cannot be used interchangeably without design re-evaluation and validation.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity AMP Connectors 4-1546701-6 (Primary Part)

The TE Connectivity part is the original specification component. Selection of this part is appropriate when:

• Original equipment manufacturer (OEM) specifications explicitly require TE Connectivity AMP Connectors products
• Design documentation references the JC6 or Buchanan series
• Supply chain agreements prioritize TE Connectivity as the primary vendor
• The 105°C operating temperature rating is sufficient for the application environment

Curtis Industries CFT-8 (Substitute Part)

The Curtis Industries CFT-8 is a direct functional equivalent that meets all critical electrical and mechanical parameters. This substitute is appropriate when:

• The primary TE Connectivity part experiences supply constraints or extended lead times
• Design flexibility permits alternative manufacturers meeting identical specifications
• The enhanced 140°C operating temperature rating provides additional thermal margin for the application
• RoHS3 compliance status aligns with current regulatory requirements
• The polyester thermoplastic insulation material meets application environmental conditions

Both parts carry identical electrical ratings (20A, 300V), accept the same wire gauge range (12-22 AWG), feature dual-wall barrier construction, and maintain UL94 V-0 flammability certification. The Curtis Industries CFT-8 includes a flange feature not present in the TE Connectivity part, which may provide enhanced mechanical stability in certain mounting configurations.

Frequently Asked Questions (FAQ)

Q: Can the Curtis Industries CFT-8 be used as a direct replacement for the TE Connectivity 4-1546701-6 in existing designs?

A: Yes. The CFT-8 meets all critical electrical and mechanical parameters: 8 circuits, 0.375" pitch, 20A current rating, 300V voltage rating, 12-22 AWG wire gauge acceptance, dual-wall barrier construction, screw top termination, and solder turret bottom termination. Both parts are UL94 V-0 rated and RoHS compliant. Physical mounting compatibility requires verification of the flange feature on the CFT-8 against the original mounting design.

Q: What is the significance of the operating temperature difference between these parts?

A: The TE Connectivity part is rated to 105°C, while the Curtis Industries CFT-8 is rated to 140°C. This difference reflects the thermal capability of the polyester thermoplastic insulation material used in the CFT-8 versus the standard thermoplastic in the TE Connectivity part. For applications operating below 105°C, both parts are equivalent. For applications requiring operation between 105°C and 140°C, the CFT-8 provides the necessary thermal margin.

Q: Are there any packaging differences between these parts?

A: The TE Connectivity 4-1546701-6 packaging information is not specified in the available data. The Curtis Industries CFT-8 is supplied in bulk packaging. Packaging format should be confirmed with the supplier based on procurement requirements.

Q: Do both parts accept the same wire gauge range?

A: Yes. Both the TE Connectivity 4-1546701-6 and Curtis Industries CFT-8 accept 12-22 AWG wire gauge, ensuring compatibility with identical wiring specifications.

Q: What does the flange feature on the Curtis Industries CFT-8 provide?

A: The flange feature on the CFT-8 provides additional mechanical support and positioning during chassis or panel mounting. This feature may enhance stability in vibration-prone environments or applications requiring precise alignment. Compatibility with the original mounting design must be verified.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both parts are RoHS compliant (TE Connectivity is RoHS Compliant; Curtis Industries is ROHS3 Compliant), carry UL94 V-0 flammability ratings, and are classified under the same HTSUS code (8536.90.4000). Both are EAR99 export classification items.

Q: What is the moisture sensitivity level for these parts?

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