Key Parameters

Substitute Part Grouping Explanation

Substitution of the BK/TDC600-10A is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Current Rating: 10A (exact match required)
• Voltage Rating: 600VAC (exact match required)
• Response Time: Fast Blow (exact match required)
• Breaking Capacity: Minimum 200A AC (exact match or higher acceptable)

Mechanical Equivalence Criteria:

• Fuse Type: Cartridge (exact match required)
• Mounting Type: Requires Holder (exact match required)
• Physical Dimensions: 0.25" Dia x 1.00" L (8AG standard form factor)

Compliance Criteria:

• Approval by recognized agencies (ASTA, BSI, UL)
• RoHS compliance status documented

The substitute part BK1/TDC600-10-R meets all electrical and mechanical equivalence criteria while offering active product status and improved compliance documentation.

Engineering Selection Recommendations

Primary Substitute: BK1/TDC600-10-R

The BK1/TDC600-10-R is the direct equivalent for the obsolete BK/TDC600-10A based on the following engineering factors:

1. Electrical Compatibility: Identical current rating (10A), voltage rating (600VAC), response time (Fast Blow), and breaking capacity (200A AC minimum). Both components are designed for the same electrical protection function.

2. Mechanical Compatibility: Both components conform to the 8AG cartridge form factor with dimensions of approximately 0.25" Dia x 1.00" L, ensuring physical compatibility with existing cartridge fuse holders.

3. Product Status: The substitute part is classified as Active, ensuring continued availability and supply chain reliability for future procurement and replacement operations.

4. Compliance Enhancement: The BK1/TDC600-10-R carries ROHS3 compliance certification, addressing modern regulatory requirements. UL approval provides recognized safety certification for North American applications.

5. Series Continuity: Both parts belong to the Eaton TDC600 series, confirming manufacturer lineage and design consistency.

Application Continuity: Direct substitution is appropriate for all electrical and industrial applications previously served by the BK/TDC600-10A, provided the fuse holder remains compatible with the 8AG cartridge standard.

Frequently Asked Questions (FAQ)

Q: Can the BK1/TDC600-10-R be used as a direct replacement for the BK/TDC600-10A?

A: Yes. Both components share identical electrical ratings (10A, 600VAC, Fast Blow response), breaking capacity (200A AC), and mechanical form factor (8AG cartridge, 0.25" Dia x 1.00" L). The substitute is compatible with any fuse holder designed for the original part.

Q: What is the difference in physical dimensions between these two parts?

A: The main part specifies 0.248" Dia x 1.000" L (6.30mm x 25.40mm), while the substitute specifies 0.250" Dia x 1.000" L (6.35mm x 25.40mm). This 0.002" (0.05mm) difference in diameter is within standard manufacturing tolerances for 8AG cartridge fuses and does not affect mechanical compatibility with standard cartridge holders.

Q: Why is the original part classified as obsolete?

A: The BK/TDC600-10A is listed as obsolete, indicating it has been discontinued by the manufacturer. The BK1/TDC600-10-R represents the active equivalent in the Eaton product line, ensuring continued availability and support.

Q: Are there any compliance differences between the two parts?

A: The original part is RoHS non-compliant, while the substitute (BK1/TDC600-10-R) is ROHS3 compliant. The original part carries ASTA and BSI approvals, while the substitute carries UL approval. Both meet the same electrical and safety standards for their respective markets.

Q: What is the breaking capacity difference?

A: The main part specifies 200A AC and 10kA DC breaking capacity. The substitute specifies 200A AC breaking capacity. Both meet the minimum 200A AC requirement for equivalent electrical protection performance.

Q: Can I use the BK1/TDC600-10-R in equipment designed for the BK/TDC600-10A?

A: Yes. The electrical ratings, response characteristics, and mechanical form factor are equivalent. The substitute will function identically in any application where the original part was specified.

Q: What packaging options are available?

A: The original part was supplied in non-standard packaging. The substitute (BK1/TDC600-10-R) is available in bulk packaging (1000 per bag), which is standard for 8AG cartridge fuses and provides efficient inventory management.
