Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BK/TDC180-13 is determined by the following critical parameters:

Current Rating: Both the main part and substitute must maintain 13A current rating to ensure proper circuit protection and prevent nuisance trips or inadequate protection.

Fuse Type & Mounting: Both parts must be cartridge-style fuses requiring holder mounting, ensuring mechanical and electrical compatibility with existing fuse holder infrastructure.

Response Time: Fast-blow characteristic must be preserved to maintain protection timing in the original circuit design.

Physical Dimensions: The 0.248" Dia x 1.000" L (6.30mm x 25.40mm) form factor must be identical to ensure proper fit within standard 8AG fuse holders.

Approval Certifications: Both ASTA and CCC certifications must be present to maintain compliance with applicable electrical standards.

Voltage Rating: The substitute part voltage rating must equal or exceed the original 240VAC specification. The BK/TDC180-13A operates at 264VAC, which exceeds the original specification and is therefore acceptable for substitution in 240VAC circuits.

Parameter Comparison

Engineering Selection Recommendations

The BK/TDC180-13A is the direct substitute for the obsolete BK/TDC180-13. Both components are manufactured by Eaton - Electronics Division within the same TDC180 series and share identical electrical and mechanical specifications with the exception of voltage rating.

The substitute part operates at 264VAC, which exceeds the original 240VAC specification. This higher voltage rating is compatible with 240VAC circuit applications, as fuses rated for higher voltages maintain the same current-limiting and protection characteristics at lower voltages.

The BK/TDC180-13A maintains active product status with confirmed RoHS compliance, ensuring long-term availability and regulatory alignment. Both parts retain ASTA and CCC certifications, confirming compliance with applicable electrical safety standards.

Physical compatibility is confirmed through identical dimensions (0.248" Dia x 1.000" L) and cartridge form factor, ensuring direct installation into existing 8AG fuse holders without modification.

Frequently Asked Questions (FAQ)

Q: Can the BK/TDC180-13A be used as a direct replacement for the BK/TDC180-13?

A: Yes. The BK/TDC180-13A is a direct substitute. Both components share identical current rating (13A), fuse type (cartridge), response time (fast-blow), breaking capacity (6kA), and physical dimensions (0.248" Dia x 1.000" L). The substitute operates at 264VAC, which is compatible with 240VAC applications.

Q: What is the significance of the higher voltage rating on the substitute part?

A: The BK/TDC180-13A is rated for 264VAC compared to the original 240VAC. A fuse rated for higher voltage maintains the same protection characteristics when used in lower-voltage circuits. This makes the substitute suitable for 240VAC applications.

Q: Are both parts mechanically compatible with the same fuse holder?

A: Yes. Both the BK/TDC180-13 and BK/TDC180-13A are cartridge-style fuses with identical dimensions (0.248" Dia x 1.000" L) and require standard 8AG fuse holders. No holder modification is required.

Q: What certifications apply to both parts?

A: Both components carry ASTA and CCC approvals, confirming compliance with applicable electrical safety standards for cartridge fuses in electrical and industrial applications.

Q: Why is the original part listed as obsolete?

A: The BK/TDC180-13 is classified as obsolete, indicating discontinued manufacturing. The BK/TDC180-13A maintains active product status and serves as the current production equivalent within the TDC180 series.

Q: Is the substitute part RoHS compliant?

A: Yes. The BK/TDC180-13A is RoHS compliant, meeting current environmental and regulatory requirements for electrical components.
