Key Parameters

Substitute Part Grouping Explanation

Substitution of the BK/S-8001-4 is based on strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Voltage rating: 600V
• Current rating: 30A
• Number of circuits: 4
• Fuse type: Cartridge
• Fuse size: 0.25" Dia x 1.26" L (6.35mm x 32mm)
• Mounting type: Chassis Mount
• Termination style: Solder Lug
• Contact material: Spring Bronze
• Contact finish: Tin-Lead
• Series: S-8000

The substitute part S-8002-4-R maintains full electrical and mechanical compatibility with the original BK/S-8001-4 across all specified parameters. The primary distinction is product status: the original part is obsolete, while the substitute is active and available.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: S-8002-4-R

The S-8002-4-R is the direct active equivalent for the obsolete BK/S-8001-4. Selection of this substitute is based on:

1. Product Status Alignment: The substitute is classified as active, ensuring long-term availability and continued manufacturing support, whereas the original part is obsolete.

2. Electrical Equivalence: All critical electrical parameters are identical, including 600V voltage rating, 4-circuit configuration, and cartridge fuse compatibility (0.25" Dia x 1.26" L).

3. Mechanical Compatibility: Chassis mount orientation, solder lug termination, spring bronze contacts with tin-lead finish, and all dimensional specifications are maintained.

4. Regulatory Compliance: The substitute achieves RoHS compliance, whereas the original part is RoHS non-compliant. This provides improved environmental and regulatory alignment for new designs and long-term system maintenance.

5. Series Continuity: Both parts belong to the Eaton S-8000 series, confirming design family consistency.

6. Inventory Availability: The substitute maintains adequate stock levels (1134 pcs) for procurement and deployment.

Frequently Asked Questions (FAQ)

Q: Can the S-8002-4-R be used as a direct replacement for the BK/S-8001-4 in existing installations?

A: Yes. The S-8002-4-R maintains identical electrical ratings (600V, 4-circuit), mechanical dimensions (0.25" Dia x 1.26" L cartridge fuse size), mounting configuration (chassis mount), and termination style (solder lug). No circuit modifications or mechanical rework is required.

Q: What is the significance of the RoHS compliance difference between these parts?

A: The BK/S-8001-4 is RoHS non-compliant, while the S-8002-4-R is RoHS compliant. For new system designs and applications subject to environmental regulations, the S-8002-4-R is the appropriate selection. For legacy system maintenance where the original part is still in use, either part may be acceptable depending on regulatory requirements in the deployment region.

Q: Are there any differences in contact material or finish between the two parts?

A: No. Both parts use spring bronze contacts with tin-lead finish, ensuring identical electrical performance and reliability characteristics.

Q: What fuse types are compatible with both the BK/S-8001-4 and S-8002-4-R?

A: Both parts accept 3AG cartridge fuses with dimensions 1/4" x 1-1/4" (0.25" Dia x 1.26" L, or 6.35mm x 32mm). The SFE-20 standard fuse designation applies to both.

Q: Is the packaging difference between the parts significant for procurement?

A: The S-8002-4-R is supplied in bulk packaging, while the original part packaging is not specified. For high-volume procurement or integration into manufacturing workflows, bulk packaging may offer logistical advantages. Confirm packaging requirements with your procurement specifications.

Q: Are both parts available for immediate shipment?

A: Yes. The BK/S-8001-4 has 986 pcs in stock, and the S-8002-4-R has 1134 pcs in stock, both listed as new original inventory.
