Frequently Asked Questions (FAQ)

Q: Can the BK/S-8301-4-R be used as a direct replacement for the BK/S-8301-4?

A: Yes. The BK/S-8301-4-R is electrically and mechanically identical to the BK/S-8301-4 across all specified parameters, including current rating, voltage, fuse size, circuit count, mounting type, and termination style. No circuit modifications or mechanical adjustments are required.

Q: What is the difference between the BK/S-8301-4 and BK/S-8301-4-R?

A: The primary differences are product status and regulatory compliance. The BK/S-8301-4-R is an active product with ROHS3 compliance and REACH unaffected status, while the original BK/S-8301-4 is obsolete and RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns when substituting the BK/S-8301-4-R for the BK/S-8301-4?

A: No compatibility concerns exist. Both parts are from the same manufacturer (Eaton - Electronics Division), same series (S-8000), and share identical specifications for current rating, voltage, fuse size, number of circuits, mounting configuration, and termination style.

Q: What fuse types are compatible with these fuse blocks?

A: These fuse blocks are designed for 3AG cartridge fuses with dimensions 1/4" x 1-1/4" (SFE-20 specification).

Q: Is the packaging difference between the two parts significant?

A: The BK/S-8301-4-R is supplied in bulk packaging, while the original part packaging is not specified. This difference does not affect electrical or mechanical performance and relates only to order and storage considerations.
