Equivalent & Substitute Parts for BK/AGC-8/10 Glass Cartridge Fuse

Part Overview

The BK/AGC-8/10 is an 800 mA, 250 V AC/DC fast-blow glass cartridge fuse manufactured by Eaton - Electronics Division. This component is classified as obsolete and requires a fuse holder for installation. The 3AB/3AG form factor (0.250" diameter × 1.250" length) is a standard industrial fuse package. Due to the obsolete product status, equivalent substitute parts with active availability are necessary for ongoing system maintenance and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BK/AGC-8/10 is determined by strict equivalence across the following parameters:

• Current Rating: 800 mA (exact match required)
• Voltage Rating: 250 V AC (exact match required)
• Response Time: Fast Blow (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Physical Dimensions: 0.250" Dia x 1.250" L (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

All substitute parts listed below meet these criteria without deviation. Substitutes are identified as active-status components with improved compliance certifications compared to the obsolete main part.

Engineering Selection Recommendations

Primary Recommendation: BK/AGC-8/10-R

The BK/AGC-8/10-R is the direct equivalent substitute for the obsolete BK/AGC-8/10. This part maintains identical electrical and mechanical specifications while offering active product status and ROHS3 compliance certification. Current inventory availability is 897 pieces.

Secondary Recommendation: AGC-8/10-R

The AGC-8/10-R provides equivalent functionality with RoHS compliance. This part differs only in the manufacturer designation prefix and RoHS certification level (RoHS Compliant versus ROHS3 Compliant). Current inventory availability is 1031 pieces.

Both substitute parts are manufactured by Eaton - Electronics Division and are functionally interchangeable with the original BK/AGC-8/10 across all electrical and mechanical parameters. Selection between the two substitutes should be based on procurement requirements, compliance certifications needed for the end application, and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can AGC-8/10-R be used as a direct replacement for BK/AGC-8/10?

A: Yes. The AGC-8/10-R meets all electrical and mechanical specifications of the BK/AGC-8/10, including current rating (800 mA), voltage rating (250 V AC), response time (Fast Blow), package type (3AB/3AG), and physical dimensions (0.250" Dia x 1.250" L).

Q: What is the difference between AGC-8/10-R and BK/AGC-8/10-R?

A: Both parts are electrically and mechanically identical. The primary difference is the manufacturer designation prefix (AGC versus BK/AGC) and RoHS certification level (RoHS Compliant versus ROHS3 Compliant). Both are active products from Eaton - Electronics Division.

Q: Why is the original BK/AGC-8/10 listed as obsolete?

A: The BK/AGC-8/10 has been discontinued by the manufacturer. The substitute parts AGC-8/10-R and BK/AGC-8/10-R are the active-status equivalents that replace this obsolete component.

Q: Are the substitute parts compatible with existing 3AB/3AG fuse holders?

A: Yes. Both substitute parts use the identical 3AB/3AG form factor and 0.250" diameter × 1.250" length dimensions, ensuring compatibility with any holder designed for the original BK/AGC-8/10.

Q: What is the operating temperature range for these fuses?

A: All parts in this equivalence group operate across the temperature range of -55°C to 125°C.

Q: Do the substitute parts have different RoHS compliance levels?

A: Yes. The AGC-8/10-R carries RoHS Compliant certification, while the BK/AGC-8/10-R carries ROHS3 Compliant certification. Both meet RoHS requirements; ROHS3 represents a more recent compliance standard. Selection depends on application requirements.
