BK/S-8102-2 Equivalent & Substitute Parts

Part Overview

The BK/S-8102-2 is a cartridge fuse block designed for chassis mount applications in 600V electrical systems. This component functions as a holder for 3AG cartridge fuses (0.25" Dia x 1.26" L) and accommodates two independent circuits with quick connect termination. The part is manufactured by Eaton - Electronics Division and maintains Active product status with 1121 units in current inventory. Substitute parts are identified when equivalent electrical ratings, mechanical dimensions, and termination specifications are maintained across the S-8000 series.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BK/S-8102-2 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Voltage rating: 600V (mandatory match)
• Current rating: 20 A (mandatory match)
• Number of circuits: 2 (mandatory match)

Mechanical Equivalence Requirements:

• Fuse size: 0.25" Dia x 1.26" L (6.35mm x 32mm) (mandatory match)
• Mounting type: Chassis Mount (mandatory match)
• Termination style: Quick Connect - 0.187" (4.7mm) (mandatory match)

Material & Construction Requirements:

• Fuse type: Cartridge (mandatory match)
• Fuseholder type: Block (mandatory match)
• Contact material: Spring Bronze (mandatory match)
• Contact finish: Tin-Lead (mandatory match)

The substitute part S-8102-2-R meets all equivalence criteria and belongs to the same S-8000 series product line.

Parameter Comparison

Engineering Selection Recommendations

Both BK/S-8102-2 and S-8102-2-R are Active status products manufactured by Eaton - Electronics Division within the S-8000 series. Selection between these parts is based on the following factors:

Compliance & Regulatory: Both parts satisfy RoHS compliance requirements and carry identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications, confirming regulatory equivalence for export and procurement purposes.

Moisture Sensitivity: Both parts carry MSL Rating 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Inventory Availability: BK/S-8102-2 maintains higher inventory (1121 units) compared to S-8102-2-R (926 units). Selection may be influenced by supply chain requirements and lead time considerations.

Electrical & Mechanical Compatibility: All critical electrical parameters (600V, 20A, 2-circuit configuration) and mechanical specifications (fuse size, mounting type, termination style) are identical, confirming direct interchangeability in 600V chassis mount fuse block applications.

Frequently Asked Questions (FAQ)

Q: Can S-8102-2-R be used as a direct replacement for BK/S-8102-2?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical voltage ratings (600V), current ratings (20A), fuse dimensions (0.25" Dia x 1.26" L), mounting configuration (chassis mount), and termination style (quick connect 0.187"). Both are Active status products from Eaton - Electronics Division within the S-8000 series.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution is determined by equivalence in: voltage rating (600V), current rating (20A), number of circuits (2), fuse size (0.25" Dia x 1.26" L), mounting type (chassis mount), termination style (quick connect 0.187"), fuse type (cartridge), and contact materials (spring bronze with tin-lead finish).

Q: Are there any compliance differences between these parts?

A: Both parts are RoHS compliant and carry identical ECCN (EAR99) and HTSUS (8538.90.8180) classifications. The BK/S-8102-2 specifies ROHS3 compliance while S-8102-2-R specifies RoHS compliance; both designations confirm regulatory equivalence.

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

A: Both parts accommodate 3AG cartridge fuses with dimensions 0.25" Dia x 1.26" L (6.35mm x 32mm), also referenced as 1/4" x 1-1/4" (SFE-20) fuses.

Q: Is there a difference in moisture sensitivity between these parts?

A: No. Both parts carry MSL Rating 1 (Unlimited), indicating identical moisture sensitivity characteristics and no special storage or handling requirements.

Q: Which part should be selected based on availability?

A: BK/S-8102-2 has higher current inventory (1121 units) compared to S-8102-2-R (926 units). Selection may be based on supply chain requirements and procurement lead times.
