Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 1546463-9 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Terminal Block Type: Barrier Block
• Number of Circuits: 9
• Pitch: 0.325" (8.26mm)
• Number of Rows: 1
• Barrier Type: 2 Wall (Dual)
• Bottom Termination: PC Pin
• Material 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: Substitute range must accommodate specified wire sizes
• Top Termination: Screw-based termination methods are interchangeable
• Mounting Type: Variations permitted based on application context
• Operating Temperature Range: Substitute must support required operating conditions
• Insulation Material: Thermoplastic or Polypropylene acceptable
• RoHS/REACH Compliance: Active product status required

The Curtis Industries 325011-09-0 meets all mandatory matching parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 1546463-9 Primary Selection:

• Select when application requires 20A current capacity
• Select when operating temperature range must include -40°C minimum
• Select when 150V voltage rating is specified
• Select when wire gauge 12 AWG minimum is required
• Select when captive plate screw termination is mandatory

Curtis Industries 325011-09-0 Substitute Selection:

• Select when application current requirement is 15A or less
• Select when 300V voltage rating is required
• Select when operating temperature does not require below 0°C operation
• Select when wire gauge minimum of 14 AWG is acceptable
• Select when standard screw termination without captive plate is acceptable
• Select when chassis or panel mounting configuration is required

Both parts maintain active product status and UL94 V-0 flammability compliance. RoHS3 compliance of the Curtis Industries part exceeds RoHS baseline requirements. Selection between these parts depends on specific application electrical and thermal requirements.

Frequently Asked Questions (FAQ)

Q: Can Curtis Industries 325011-09-0 replace TE Connectivity 1546463-9 in all applications?

A: No. The Curtis Industries part has a lower current rating (15A versus 20A) and does not support the -40°C minimum operating temperature of the TE Connectivity part. Substitution is valid only when application current does not exceed 15A and minimum operating temperature is 0°C or higher.

Q: What is the significance of the captive plate feature on the TE Connectivity part?

A: The captive plate on the TE Connectivity 1546463-9 secures the screw during assembly and prevents loss during installation. The Curtis Industries 325011-09-0 uses standard screws without this feature. This difference affects assembly procedures but does not impact electrical performance.

Q: Are both parts suitable for PCB mounting?

A: Both parts feature PC Pin bottom termination for through-hole PCB mounting. The TE Connectivity part specifies right-angle mounting, while the Curtis Industries part supports chassis, panel, and through-hole configurations. Verify mounting orientation requirements for your application.

Q: What is the wire gauge compatibility difference?

A: The TE Connectivity 1546463-9 accepts 12-22 AWG wire, while the Curtis Industries 325011-09-0 accepts 14-22 AWG wire. If your application requires 12 AWG wire termination, only the TE Connectivity part is suitable.

Q: Do both parts meet current environmental compliance standards?

A: Yes. Both parts are active products with UL94 V-0 flammability ratings and unlimited moisture sensitivity (MSL 1). The Curtis Industries part carries ROHS3 compliance, which exceeds the RoHS baseline compliance of the TE Connectivity part. Both are suitable for environmentally regulated applications.

Q: What is the voltage rating difference and when does it matter?

A: The Curtis Industries 325011-09-0 has a 300V rating versus the TE Connectivity 1546463-9 at 150V. Select the Curtis Industries part when application voltage exceeds 150V. For applications at or below 150V, either part is acceptable from a voltage perspective.

Q: Can these parts be intermixed in the same assembly?

A: Both parts have identical circuit count (9), pitch (0.325"), row configuration (1), and barrier type (2 Wall Dual). Physical and electrical intermixing is possible, but this practice is not recommended in production environments. Maintain consistent part selection within a single assembly.
