Substitute Part Grouping Explanation

Substitution of the BK/TDC180-2 is determined by strict equivalence across the following electrical and mechanical parameters:

• Current Rating: 2A (exact match required)
• Voltage Rating - AC: 240 VAC (exact match required)
• Fuse Type: Cartridge (exact match required)
• Package / Case: 8AG, 1/4" x 1" (exact match required)
• Physical Dimensions: 0.248" Dia x 1.000" L / 6.30mm x 25.40mm (exact match required)
• Response Time: Fast Blow (exact match required)
• Breaking Capacity: 6kA (exact match required)
• Approval Agencies: ASTA, CCC (exact match required)

The substitute part BK1/TDC180-2A meets all these criteria and is classified as an active product, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The BK1/TDC180-2A is the direct equivalent for the obsolete BK/TDC180-2. Both components share identical electrical specifications, mechanical dimensions, and regulatory certifications (ASTA, CCC). The substitute part is currently in active production status with significantly higher inventory availability (1803 pieces versus 663 pieces for the obsolete part).

Selection of BK1/TDC180-2A is appropriate for all applications previously served by BK/TDC180-2. The active product status ensures long-term supply chain reliability and continued manufacturing support. Both parts comply with identical regulatory frameworks and carry equivalent RoHS and REACH compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can BK1/TDC180-2A be used as a direct replacement for BK/TDC180-2?

A: Yes. Both components are identical in electrical rating (2A, 240VAC), fuse type (cartridge, fast-blow), physical dimensions (8AG, 0.248" Dia x 1.000" L), breaking capacity (6kA), and regulatory approvals (ASTA, CCC). Direct substitution is valid without circuit modification.

Q: What is the difference between these two part numbers?

A: The primary difference is product status. BK/TDC180-2 is obsolete, while BK1/TDC180-2A is active. The packaging differs (dash versus bulk), but electrical and mechanical specifications are identical. The part number suffix change reflects the active product designation.

Q: Are there any compatibility concerns with existing fuse holders?

A: No. Both parts use the 8AG cartridge format with identical physical dimensions (0.248" Dia x 1.000" L). They are mechanically and electrically compatible with any holder designed for 8AG cartridge fuses.

Q: What certifications apply to the substitute part?

A: BK1/TDC180-2A carries ASTA and CCC approvals, identical to the main part. The substitute is ROHS3 compliant and REACH unaffected, providing equivalent regulatory compliance.

Q: Is inventory availability a factor in selecting the substitute?

A: BK1/TDC180-2A has higher current inventory (1803 pieces) compared to BK/TDC180-2 (663 pieces). Given the obsolete status of the main part, the substitute offers superior supply chain continuity.
