TE Connectivity AMP Connectors 1546465-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 1546465-2 is a 2-circuit barrier block connector with 0.325" (8.26mm) pitch, designed for chassis and panel mounting applications. This terminal block features dual-wall barrier construction, screw termination on top, and PC pin termination on the bottom. The component is classified as Active product status and is RoHS Compliant, making it suitable for current industrial and commercial applications requiring reliable electrical connections in the 12-22 AWG wire gauge range.

Equivalent and substitute parts are identified when alternative manufacturers offer terminal blocks with compatible electrical ratings, mechanical dimensions, and functional characteristics that allow direct replacement in circuit designs without requiring layout or schematic modifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the TE Connectivity 1546465-2 terminal block is determined by the following critical parameters that must remain constant across equivalent parts:

Mandatory Matching Parameters:

• Terminal block type: Barrier Block
• Number of circuits: 2
• Pitch spacing: 0.325" (8.26mm)
• Number of rows: 1
• Top termination method: Screws
• Bottom termination method: PC Pin
• Barrier construction: 2 Wall (Dual)
• Mounting configuration: Chassis, Panel; Through Hole
• Flammability rating: UL94 V-0

Allowable Variation Parameters:

• Current rating (Amps): Substitute must meet or exceed application requirements
• Voltage rating: Substitute must meet or exceed application requirements
• Wire gauge range: Substitute must accommodate specified wire sizes
• Operating temperature range: Substitute must cover application temperature envelope
• Insulation material: May vary if flammability rating is maintained
• RoHS compliance status: Both RoHS2 and RoHS3 compliant parts are acceptable

The Curtis Industries 325010-02-0 qualifies as a substitute part based on matching all mandatory parameters while maintaining electrical and thermal performance within acceptable operating ranges.

Engineering Selection Recommendations

TE Connectivity 1546465-2 (Primary Part)

Select this part for applications requiring the full current rating of 20A and operating temperature range extending to -40°C. The thermoplastic insulation material and zinc, clear chromate terminal screw finish provide the specified performance envelope. RoHS Compliant status confirms environmental compliance for regulated markets.

Curtis Industries 325010-02-0 (Substitute Part)

This part is suitable for applications where the current requirement does not exceed 15A and the minimum operating temperature does not fall below 0°C. The higher voltage rating of 300V provides additional margin in high-voltage applications. ROHS3 Compliant status indicates compliance with the latest regulatory requirements. The polypropylene insulation material maintains the UL94 V-0 flammability rating required for safety-critical applications.

Substitution Constraints:

The Curtis Industries 325010-02-0 cannot be used as a direct substitute in applications requiring 20A current capacity or operating temperatures below 0°C. Wire gauge compatibility is limited to 14-22 AWG, excluding 12 AWG applications. Selection between these parts must be based on specific application current, temperature, and wire gauge requirements.

Frequently Asked Questions (FAQ)

Q: Can the Curtis Industries 325010-02-0 replace the TE Connectivity 1546465-2 in all applications?

A: No. The Curtis Industries part has a maximum current rating of 15A compared to 20A for the TE Connectivity part. Substitution is only valid for applications requiring 15A or less. Additionally, the Curtis Industries part does not specify a minimum operating temperature, while the TE Connectivity part operates to -40°C.

Q: What is the significance of the pitch specification in terminal block substitution?

A: Pitch (0.325" or 8.26mm) determines the physical spacing between circuits on the printed circuit board. Both parts share identical pitch specifications, ensuring mechanical compatibility with existing PCB layouts and connector housings.

Q: Are there wire gauge compatibility issues between these parts?

A: Yes. The TE Connectivity 1546465-2 accepts 12-22 AWG wire, while the Curtis Industries 325010-02-0 accepts 14-22 AWG wire. Applications using 12 AWG wire cannot use the Curtis Industries substitute.

Q: How do the voltage ratings affect substitution decisions?

A: The Curtis Industries 325010-02-0 has a 300V rating compared to 150V for the TE Connectivity part. The higher voltage rating provides additional safety margin in high-voltage applications but does not prevent substitution in lower-voltage circuits. Voltage rating selection must match or exceed the application requirement.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant status?

A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. RoHS Compliant refers to RoHS2 (2011/65/EU), while ROHS3 Compliant refers to the updated directive (EU) 2015/863. Both parts meet current environmental compliance requirements for regulated markets.

Q: Does the insulation material difference affect electrical performance?

A: Both thermoplastic and polypropylene insulation materials achieve UL94 V-0 flammability rating. The material difference does not affect electrical performance in standard applications but may influence mechanical properties and chemical resistance in specialized environments.

Q: Are the PC pin terminations identical between these parts?

A: Both parts feature PC pin bottom termination compatible with standard printed circuit board through-hole mounting. The mechanical and electrical characteristics of the PC pin interface are equivalent for both parts.

Q: What inventory considerations apply to these substitute parts?

A: The TE Connectivity 1546465-2 has 780 pieces in stock, while the Curtis Industries 325010-02-0 has 896 pieces in stock. Availability may influence part selection for time-sensitive applications.
