Engineering Selection Recommendations

The BK/S-8301-3-R is the direct equivalent for the obsolete BK/S-8301-3. Selection of the substitute part is based on the following factors:

Product Status: The original part is classified as obsolete, making the active BK/S-8301-3-R the appropriate choice for new procurement and system replacements.

Compliance Certification: The BK/S-8301-3-R achieves ROHS3 compliance and REACH Unaffected status, providing enhanced regulatory alignment compared to the non-compliant original part.

Electrical and Mechanical Equivalence: All critical parameters—voltage, current, circuit count, fuse dimensions, mounting configuration, and termination method—are identical between the original and substitute parts, ensuring direct functional interchangeability.

Availability: The BK/S-8301-3-R maintains active inventory status with 3994 units in stock, compared to the limited obsolete inventory of the original part.

Frequently Asked Questions (FAQ)

Q: Can the BK/S-8301-3-R be used as a direct replacement for the BK/S-8301-3?

A: Yes. The BK/S-8301-3-R is a direct equivalent. All electrical parameters (600V, 30 A, 3 circuits) and mechanical specifications (fuse size, chassis mount, screw terminal) are identical, ensuring functional interchangeability in existing applications.

Q: What is the difference between the original and substitute part?

A: The primary differences are product status and compliance certification. The BK/S-8301-3-R is an active product with ROHS3 compliance and REACH Unaffected status, whereas the original BK/S-8301-3 is obsolete and RoHS non-compliant.

Q: Are there any compatibility concerns when substituting the BK/S-8301-3-R for the BK/S-8301-3?

A: No compatibility concerns exist. The substitute part maintains identical electrical ratings, mechanical dimensions, mounting configuration, and termination style. The fuse cartridge size (0.25" Dia x 1.26" L) and compatible fuse type (3AG, 1/4" x 1-1/4") remain unchanged.

Q: What packaging options are available for the BK/S-8301-3-R?

A: The BK/S-8301-3-R is supplied in bulk packaging. Packaging specifications for the original part were not provided in the technical documentation.

Q: Is the BK/S-8301-3-R suitable for new system designs?

A: Yes. As an active product with current compliance certifications (ROHS3, REACH Unaffected), the BK/S-8301-3-R is appropriate for new designs requiring a 30 A, 600V, 3-circuit cartridge fuse block with chassis mount configuration.
