Key Parameters

Substitute Part Grouping Explanation

Substitution of the BK/TDC180-1 is determined by strict equivalence across the following parameters:

• Current Rating: 1A (exact match required)
• Voltage Rating: 240VAC (exact match required)
• Fuse Type: Cartridge (exact match required)
• Response Time: Fast Blow (exact match required)
• Physical Form Factor: 8AG, 1/4" x 1" (exact match required)
• Breaking Capacity: 6kA (exact match required)
• Approval Agencies: ASTA, CCC (minimum compliance required)

The substitute part BK1/TDC180-1A meets all electrical and mechanical parameters identical to the main part. The primary distinction is product status: BK1/TDC180-1A is active, whereas BK/TDC180-1 is obsolete.

Frequently Asked Questions (FAQ)

Q: Can BK1/TDC180-1A be used as a direct replacement for BK/TDC180-1?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters: 1A current rating, 240VAC voltage rating, fast-blow response, 8AG form factor, and 6kA breaking capacity. Physical dimensions and holder compatibility are identical.

Q: What is the primary reason to transition from BK/TDC180-1 to BK1/TDC180-1A?

A: BK/TDC180-1 is obsolete. BK1/TDC180-1A is active and maintains current manufacturing support, ensuring long-term availability and supply chain continuity.

Q: Are there compliance differences between the two parts?

A: BK1/TDC180-1A explicitly declares ROHS3 compliance and REACH unaffected status. Both parts carry ASTA and CCC approvals and share identical ECCN and HTSUS classifications.

Q: Does the packaging difference affect compatibility?

A: No. BK1/TDC180-1A is supplied in bulk packaging, which does not affect electrical performance or mechanical fit. The fuse itself is identical in form factor and dimensions.

Q: Are there any application restrictions for BK1/TDC180-1A?

A: No. BK1/TDC180-1A is rated for identical electrical and industrial applications as BK/TDC180-1, with no additional restrictions.

Q: What is the moisture sensitivity level for BK1/TDC180-1A?

A: MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.
