BK/TDC180-10 Equivalent & Substitute Parts

Part Overview

The BK/TDC180-10 is a cartridge fuse rated at 10A, 240VAC with fast-blow response characteristics, manufactured by Eaton - Electronics Division. This component is classified as obsolete, requiring identification of active equivalent parts to maintain system functionality and ensure continued availability for replacement applications.

The necessity to identify substitute parts stems from the obsolete product status of the BK/TDC180-10. Active equivalent models ensure procurement continuity and support for electrical and industrial applications requiring 10A cartridge fuse protection.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BK/TDC180-10 is determined by the following critical parameters:

Current Rating: 10A (must match exactly)

Fuse Type & Package: Cartridge format, 8AG standard, 0.248" Dia x 1.000" L dimensions (physical compatibility with existing holders)

Response Characteristic: Fast Blow (functional equivalence for circuit protection timing)

Breaking Capacity: 6kA at rated voltage (protective performance specification)

Mounting Configuration: Requires Holder (system integration requirement)

Approval Certifications: ASTA and CCC compliance (regulatory and safety standards)

The substitute part BK/TDC180-10A maintains all critical parameters within the allowed electrical and mechanical specifications for this product category. The voltage rating differential (264VAC vs. 240VAC) represents an uprated specification that does not compromise compatibility, as the substitute operates at a higher voltage threshold while maintaining identical current, physical dimensions, response time, and breaking capacity characteristics.

Parameter Comparison

Engineering Selection Recommendations

The BK/TDC180-10A is the direct active equivalent for the obsolete BK/TDC180-10. Selection is based on the following engineering criteria:

Product Status: The BK/TDC180-10A maintains active product status with current manufacturing and distribution support, whereas the BK/TDC180-10 is obsolete and subject to availability constraints.

Electrical Equivalence: Both parts maintain identical current rating (10A), response time (Fast Blow), breaking capacity (6kA), and physical dimensions (0.248" Dia x 1.000" L). The voltage rating increase from 240VAC to 264VAC represents an uprated specification that does not restrict application in 240VAC circuits.

Regulatory Compliance: Both parts carry ASTA and CCC approvals. The BK/TDC180-10A additionally meets RoHS compliance requirements, supporting modern procurement and environmental standards.

Physical Compatibility: Identical cartridge dimensions and holder mounting requirements ensure direct mechanical substitution without modification to existing fuse holders or electrical enclosures.

For new designs and replacement applications, the BK/TDC180-10A is the specified equivalent part for the BK/TDC180-10.

Frequently Asked Questions (FAQ)

Q: Can the BK/TDC180-10A be used in place of the BK/TDC180-10?

A: Yes. The BK/TDC180-10A is the direct active equivalent. Both parts share identical current rating (10A), response time (Fast Blow), physical dimensions (0.248" Dia x 1.000" L), breaking capacity (6kA), and holder mounting requirements. The higher voltage rating (264VAC vs. 240VAC) does not restrict use in 240VAC applications.

Q: What is the difference between the 240VAC and 264VAC ratings?

A: The 264VAC rating represents an uprated voltage specification. A fuse rated for 264VAC operates safely in circuits rated at 240VAC. The higher rating provides additional margin and does not affect current-limiting performance or response time.

Q: Are the physical dimensions identical?

A: Yes. Both the BK/TDC180-10 and BK/TDC180-10A measure 0.248" Dia x 1.000" L (6.30mm x 25.40mm) and use the standard 8AG cartridge format. Direct installation in existing fuse holders is supported without modification.

Q: Do both parts meet the same safety certifications?

A: Yes. Both parts carry ASTA and CCC approvals. The BK/TDC180-10A additionally meets RoHS compliance, supporting current environmental and procurement standards.

Q: Why is the BK/TDC180-10 listed as obsolete?

A: Obsolete status indicates the part is no longer in active production. The BK/TDC180-10A serves as the active replacement, ensuring continued availability and support for applications requiring 10A, 240VAC cartridge fuse protection.

Q: What is the breaking capacity specification?

A: Both parts have a breaking capacity of 6kA at rated voltage. This specification defines the maximum fault current the fuse can safely interrupt without damage or hazard.

Q: Can these parts be used interchangeably in existing systems?

A: Yes. Identical current rating, response time, physical dimensions, and holder compatibility support direct interchangeability. The BK/TDC180-10A is the specified replacement for the obsolete BK/TDC180-10.
