AGC-9-R Equivalent & Substitute Parts Reference

Part Overview

The AGC-9-R is a 9 A, 250 V AC/DC fast-blow glass cartridge fuse manufactured by Eaton - Electronics Division. This component is designed for use in 3AB and 3AG fuse holders with 1/4" x 1-1/4" dimensions. The part maintains Active product status and is RoHS Compliant, making it suitable for current circuit protection applications requiring fast-response fusing characteristics. Substitute parts are identified when equivalent electrical and mechanical parameters are required for component sourcing, inventory management, or supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AGC-9-R is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Current Rating: 9 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Response Time: Fast Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 200 A (exact match required)

Mechanical Parameters:

• Fuse Type: Cartridge, Glass (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Mounting Type: Requires Holder (exact match required)

Compliance Parameters:

• Approval Agencies: CSA, UL (minimum requirement)
• RoHS Status: RoHS Compliant or ROHS3 Compliant (acceptable)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

The substitute part BK/AGC-9-R meets all critical electrical, mechanical, and compliance requirements for direct substitution with the AGC-9-R.

Parameter Comparison

Engineering Selection Recommendations

Both AGC-9-R and BK/AGC-9-R are Active products manufactured by Eaton - Electronics Division with identical electrical and mechanical specifications. Selection between these parts is based on availability and compliance requirements:

AGC-9-R: RoHS Compliant status. Current inventory: 861 Pcs New Original In Stock.

BK/AGC-9-R: ROHS3 Compliant status with additional REACH Unaffected designation. Current inventory: 1808 Pcs New Original In Stock. Higher inventory availability supports supply chain continuity.

Both parts carry CSA and UL approvals, operate across -55°C to 125°C, and are rated for 9 A at 250 V AC with 200 A breaking capacity. Direct substitution is permissible without circuit redesign or holder modification.

Frequently Asked Questions (FAQ)

Q: Can BK/AGC-9-R replace AGC-9-R in existing applications?

A: Yes. Both parts are electrically and mechanically identical with matching current ratings (9 A), voltage ratings (250 V AC), response characteristics (Fast Blow), and package dimensions (3AB, 3AG, 1/4" x 1-1/4"). No circuit modifications are required.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: ROHS3 Compliant represents an updated compliance designation. Both statuses indicate conformance to Restriction of Hazardous Substances requirements. BK/AGC-9-R carries the more recent ROHS3 designation.

Q: Are both parts compatible with 3AB and 3AG fuse holders?

A: Yes. Both AGC-9-R and BK/AGC-9-R are designed for use in 3AB and 3AG fuse holders with matching 1/4" x 1-1/4" dimensions. No holder modification is necessary.

Q: What is the breaking capacity specification?

A: Both parts have a breaking capacity of 200 A at rated voltage (250 V AC), indicating the maximum fault current the fuse can safely interrupt.

Q: Do these fuses require a holder for installation?

A: Yes. Both AGC-9-R and BK/AGC-9-R are cartridge-type fuses that require a compatible 3AB or 3AG fuse holder for proper installation and operation.

Q: What is the melting I²t value and why is it important?

A: The melting I²t value for both parts is 395.28. This parameter defines the thermal energy required to melt the fuse element and is critical for coordinating fuse protection with circuit requirements.
