TPCC-R-2A Equivalent & Substitute Parts

Part Overview

The TPCC-R-2A is a 2A ceramic cartridge fuse rated for 600VAC and 300VDC operation with slow blow response characteristics. Manufactured by OptiFuse, this component is classified as Active product status and is designed for applications requiring time-delay fuse protection in electrical and industrial systems. The fuse operates in a 5AG (10mm x 38mm Midget) form factor and requires a compatible holder for installation. Substitute parts are identified when equivalent electrical ratings, mechanical dimensions, and functional characteristics align with the original specification, enabling direct replacement in existing fuse holder assemblies.

Substitute Part Grouping Explanation

Substitution eligibility for the TPCC-R-2A is determined by strict alignment of the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Current Rating: 2 A (exact match required)
• Voltage Rating - AC: 600 V (exact match required)
• Voltage Rating - DC: 300 V (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: 5AG, 10mm x 38mm (Midget) (exact match required)
• Mounting Type: Requires Holder (exact match required)

The TPK-R-2A meets all critical substitution parameters. Both components share identical current ratings, voltage ratings, response characteristics, and mechanical form factors. Both are manufactured by OptiFuse and maintain Active product status. Dimensional specifications remain within acceptable tolerance ranges for holder compatibility. Both components comply with ROHS3 requirements and carry identical ECCN and HTSUS classifications.

Parameter Comparison

Engineering Selection Recommendations

Both the TPCC-R-2A and TPK-R-2A are Active status products manufactured by OptiFuse with full ROHS3 compliance. The TPK-R-2A carries cULus and UL 248 approval certifications, providing additional regulatory validation for applications requiring third-party certification documentation.

The primary technical distinction between these components is the DC breaking capacity specification: the TPCC-R-2A is rated at 100kA DC while the TPK-R-2A is rated at 10kA DC. This difference must be evaluated against the specific application requirements. For applications where DC breaking capacity of 100kA is mandatory, the TPCC-R-2A remains the required selection. For applications where 10kA DC breaking capacity is sufficient, the TPK-R-2A provides an equivalent substitute with enhanced certification credentials.

Both components share identical AC breaking capacity (200kA), current rating (2A), voltage ratings (600VAC/300VDC), response time (Slow Blow), and mechanical form factor (5AG, 10mm x 38mm Midget). Dimensional tolerances between the two parts are within acceptable ranges for standard fuse holder compatibility.

Frequently Asked Questions (FAQ)

Q: Can the TPK-R-2A directly replace the TPCC-R-2A in existing installations?

A: Direct replacement is possible when the application DC breaking capacity requirement does not exceed 10kA. The TPK-R-2A meets all electrical ratings and mechanical specifications for 5AG holder compatibility. If the original design specifies 100kA DC breaking capacity, the TPCC-R-2A must be retained.

Q: What is the significance of the different DC breaking capacity ratings?

A: Breaking capacity defines the maximum fault current the fuse can safely interrupt without rupturing or creating hazardous conditions. The TPCC-R-2A supports 100kA DC interruption while the TPK-R-2A supports 10kA DC interruption. Selection depends on the maximum DC fault current present in the circuit.

Q: Are both parts compatible with the same fuse holders?

A: Yes. Both components conform to the 5AG (10mm x 38mm Midget) standard form factor. Dimensional specifications are within tolerance ranges for standard 5AG holder compatibility. No holder modification is required for substitution.

Q: What certifications does each part carry?

A: The TPCC-R-2A carries no specified approval agency designation in the provided documentation. The TPK-R-2A carries cULus and UL 248 certifications, indicating compliance with UL fuse standards. Applications requiring third-party certification documentation should specify the TPK-R-2A.

Q: Are both parts RoHS compliant?

A: Yes. Both the TPCC-R-2A and TPK-R-2A are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8535.10.0040) classifications.

Q: What is the difference between ceramic and standard cartridge fuse construction?

A: The TPCC-R-2A is specified as a ceramic cartridge fuse, while the TPK-R-2A is specified as a cartridge fuse without material designation. Both operate with identical electrical characteristics and mechanical form factors. The material difference does not affect electrical substitution eligibility.

Q: Can inventory availability influence substitution decisions?

A: Inventory levels are independent of substitution eligibility. The TPCC-R-2A has 971 units in stock while the TPK-R-2A has 3365 units in stock. Substitution decisions must be based on electrical and mechanical compatibility, not inventory status.
