Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BK/S-8301-2 is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Current rating (30 A), voltage rating (600V), and number of circuits (2) must be identical
• Mechanical Specifications: Fuse size (0.25" Dia x 1.26" L), mounting type (Chassis Mount), and termination style (Screw Terminal) must match exactly
• Material Specifications: Contact material (Spring Bronze) and contact finish (Tin-Lead) must be identical
• Series Compatibility: Parts must belong to the S-8000 series
• Fuse Type: Cartridge type with 3AG, 1/4" x 1-1/4" (SFE-20) compatibility

The substitute part BK/S-8301-2-R meets all these criteria and is therefore classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

BK/S-8301-2 is suitable for applications where RoHS non-compliant components are acceptable and inventory availability of 746 units meets project requirements.

BK/S-8301-2-R is the preferred selection for applications requiring ROHS3 compliance and REACH unaffected status. This variant provides superior regulatory alignment for modern industrial and commercial installations. The higher inventory level (1484 units) supports larger production volumes and extended lead-time protection.

Both parts are classified as Active products with identical electrical and mechanical specifications. Selection between them depends solely on regulatory compliance requirements and inventory availability for the specific application.

Frequently Asked Questions (FAQ)

Q: Can BK/S-8301-2-R be used as a direct replacement for BK/S-8301-2?

A: Yes. All electrical specifications (30 A, 600V, 2-circuit), mechanical dimensions (0.25" Dia x 1.26" L), mounting configuration (Chassis Mount), and termination style (Screw Terminal) are identical. The parts are functionally equivalent.

Q: What is the difference between BK/S-8301-2 and BK/S-8301-2-R?

A: The primary differences are regulatory compliance and inventory levels. BK/S-8301-2-R is ROHS3 compliant and REACH unaffected, while BK/S-8301-2 is RoHS non-compliant. BK/S-8301-2-R has higher current inventory (1484 units vs. 746 units).

Q: Are these parts compatible with 3AG fuses?

A: Yes. Both parts are designed for use with 3AG, 1/4" x 1-1/4" (SFE-20) cartridge fuses.

Q: What is the moisture sensitivity level for these fuse blocks?

A: Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Which part should be selected for new designs?

A: BK/S-8301-2-R is recommended for new designs due to ROHS3 compliance and REACH unaffected status, ensuring alignment with current regulatory standards.

Q: Can these parts be used in 480V applications?

A: No. Both parts are rated for 600V maximum. They are not suitable for voltage ratings exceeding 600V.

Q: What is the current rating capacity of these fuse blocks?

A: Both parts are rated for 30 A continuous current per circuit in 2-circuit configurations.
