BK/TDC600-2A Fuse Cartridge Equivalent & Substitute Parts

Part Overview

The BK/TDC600-2A is a 2A 600 VAC fast-blow fuse cartridge manufactured by Eaton - Electronics Division. This component is classified as obsolete and requires a holder for installation in electrical and industrial applications. Due to its obsolete product status, identifying equivalent substitute parts with matching electrical and mechanical specifications is essential for system maintenance, repair, and component replacement in existing installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BK/TDC600-2A is determined by strict equivalence across the following electrical and mechanical parameters:

• Current Rating: Must be 2A
• Voltage Rating (AC): Must be 600 VAC
• Response Time: Must be Fast Blow
• Fuse Type: Must be Cartridge
• Mounting Type: Must require holder installation
• Breaking Capacity: Must meet or exceed 200A AC at rated voltage
• Physical Dimensions: Must be compatible with standard 8AG cartridge form factor (0.250" Dia x 1.000" L)

The substitute part BK-TDC600-2-R meets all these criteria and is classified as an active product, making it a direct functional equivalent for the obsolete BK/TDC600-2A.

Parameter Comparison

Engineering Selection Recommendations

The BK-TDC600-2-R is the direct substitute for the obsolete BK/TDC600-2A based on electrical and mechanical parameter equivalence. Both components share identical current rating (2A), voltage rating (600 VAC), response time (Fast Blow), and fuse type (Cartridge). Physical dimensions are within standard 8AG cartridge specifications with negligible tolerance differences (0.002" diameter variation).

The BK-TDC600-2-R holds active product status from Eaton - Electronics Division and carries UL approval certification. The substitute part is ROHS3 compliant, whereas the original part is non-compliant. For applications requiring RoHS compliance, the BK-TDC600-2-R is the appropriate selection. Both components are classified under the same HTSUS code (8536.10.0040) and ECCN (EAR99).

Frequently Asked Questions (FAQ)

Q: Can the BK-TDC600-2-R directly replace the BK/TDC600-2A in existing installations?

A: Yes. Both components are 2A 600 VAC fast-blow cartridge fuses with identical electrical ratings and compatible physical dimensions. The BK-TDC600-2-R fits standard 8AG cartridge holders designed for the original part.

Q: What is the difference between the package designations "Cartridge, Non-Standard" and "8AG, 1/4" x 1""?

A: The BK-TDC600-2-R uses the standardized 8AG cartridge form factor (1/4" x 1"), which is the industry-standard designation for this fuse size. The original part uses a non-standard designation but maintains compatible physical dimensions within normal manufacturing tolerances.

Q: Are there compliance differences between the two parts?

A: Yes. The BK-TDC600-2-R is ROHS3 compliant and carries UL certification, while the BK/TDC600-2A is RoHS non-compliant and carries ASTA and BSI certifications. For new installations or systems requiring RoHS compliance, the BK-TDC600-2-R is the appropriate choice.

Q: What is the breaking capacity difference?

A: The BK/TDC600-2A specifies 200A AC and 10kA DC breaking capacity. The BK-TDC600-2-R specifies 200A AC breaking capacity. Both meet the 200A AC requirement at rated voltage.

Q: Are both parts available in the same packaging quantities?

A: Both components are available in bulk packaging. Inventory availability should be confirmed with the supplier for current stock levels.
