Equivalent & Substitute Parts for BK/C515-1A

Part Overview

The BK/C515-1A is a 1 A, 250 V AC/DC glass cartridge fuse in 2AG package format (5mm x 15mm axial). This fuse is classified as obsolete product status. The C515 series fuses are designed for through-hole mounting applications requiring slow-blow response characteristics with CSA and UL approval. Due to obsolete status, identification of active equivalent parts is necessary to ensure continued component availability and supply chain continuity for new designs and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BK/C515-1A is based on electrical and mechanical parameter equivalence within the C515 series from Eaton - Electronics Division. The substitute part BK/C515-1-R maintains identical specifications across all critical parameters: current rating (1 A), voltage rating (250 V AC), fuse type (cartridge glass), package format (2AG, 5mm x 15mm axial), response time (slow blow), breaking capacity (35 A), and approval certifications (CSA, UL). The primary distinction is product status: BK/C515-1A is obsolete while BK/C515-1-R is active, and packaging configuration differs (standard versus bulk). Both parts share the same melting I²t value (14.289) and DC cold resistance (0.14 Ohms), confirming functional equivalence.

Engineering Selection Recommendations

BK/C515-1-R is the direct active equivalent for BK/C515-1A. Selection of BK/C515-1-R is appropriate for all applications currently using BK/C515-1A, as electrical and mechanical parameters are identical. BK/C515-1-R offers the additional advantage of active product status, ensuring long-term availability and supply chain reliability. BK/C515-1-R achieves ROHS3 compliance, whereas BK/C515-1A is non-compliant; this distinction is relevant for applications subject to RoHS regulatory requirements. Both parts carry CSA and UL approvals, maintaining certification equivalence. The packaging difference (standard versus bulk) does not affect functional performance and reflects inventory management practices only.

Frequently Asked Questions (FAQ)

Q: Can BK/C515-1-R be used as a direct replacement for BK/C515-1A in existing designs?

A: Yes. BK/C515-1-R is electrically and mechanically equivalent to BK/C515-1A. All critical parameters including current rating (1 A), voltage rating (250 V AC), fuse type (cartridge glass), package format (2AG, 5mm x 15mm), response time (slow blow), and approval certifications (CSA, UL) are identical. No circuit modifications are required.

Q: What is the difference between BK/C515-1A and BK/C515-1-R?

A: The primary differences are product status and regulatory compliance. BK/C515-1A is obsolete; BK/C515-1-R is active. BK/C515-1-R is ROHS3 compliant while BK/C515-1A is non-compliant. Packaging configuration differs (standard versus bulk). All electrical and mechanical specifications are identical.

Q: Are the physical dimensions identical between BK/C515-1A and BK/C515-1-R?

A: Yes. Both parts share identical dimensions: 0.217" diameter x 0.598" length (5.50mm x 15.20mm). Both use 2AG package format for through-hole mounting. No PCB layout modifications are necessary.

Q: Do both parts have the same breaking capacity?

A: Yes. Both BK/C515-1A and BK/C515-1-R have a breaking capacity of 35 A at rated voltage (250 V AC). The melting I²t value is identical at 14.289 for both parts.

Q: Is RoHS compliance a factor in selecting between these parts?

A: RoHS compliance is relevant only if your application or regulatory environment requires it. BK/C515-1-R is ROHS3 compliant; BK/C515-1A is not. If RoHS compliance is mandatory, BK/C515-1-R must be selected. If not required, both parts are functionally equivalent.

Q: What certifications do these fuses carry?

A: Both BK/C515-1A and BK/C515-1-R carry CSA and UL approvals, confirming compliance with North American safety standards for cartridge fuses.
