AGC-V-3-R Equivalent & Substitute Parts

Part Overview

The AGC-V-3-R is a 3 A, 250 V AC/DC fast-blow glass cartridge fuse manufactured by Eaton - Electronics Division. This through-hole component is designed for circuit protection applications requiring fast response characteristics. The fuse is housed in a 3AB/3AG package format with dimensions of 0.266" diameter by 1.292" length (6.76mm x 32.82mm). The part maintains Active product status and is RoHS Compliant, making it suitable for modern electronic equipment designs. Substitute parts are identified when original inventory becomes unavailable or when alternative sourcing is required while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AGC-V-3-R is permissible with parts that maintain identical electrical and mechanical specifications. The critical parameters that determine substitutability are:

• Current Rating: 3 A
• Voltage Rating (AC): 250 V
• Fuse Type: Cartridge, Glass
• Response Time: Fast Blow
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (Axial)
• Mounting Type: Through Hole
• Breaking Capacity @ Rated Voltage: 100 A
• Melting I²t: 45.9
• Operating Temperature Range: -55°C ~ 125°C
• DC Cold Resistance: 0.035 Ohms

Parts meeting all these specifications are functionally equivalent and may be used interchangeably in circuit protection applications designed for the AGC-V-3-R.

Parameter Comparison

Engineering Selection Recommendations

Both the AGC-V-3-R and BK/AGC-V-3-R are manufactured by Eaton - Electronics Division and maintain Active product status. All electrical and mechanical parameters are identical, including current rating, voltage rating, fuse type, response time, package format, mounting configuration, breaking capacity, melting I²t, approval agencies (CSA, UL), operating temperature range, and DC cold resistance.

The BK/AGC-V-3-R carries ROHS3 Compliant status with REACH Unaffected designation, while the AGC-V-3-R is RoHS Compliant. Both parts satisfy regulatory compliance requirements for modern electronic equipment. Selection between these parts may be based on inventory availability, supply chain considerations, or specific regulatory requirements of the end application.

Frequently Asked Questions (FAQ)

Q: Can the BK/AGC-V-3-R be used as a direct replacement for the AGC-V-3-R?

A: Yes. Both parts are manufactured by Eaton - Electronics Division and share identical electrical specifications (3 A, 250 V AC/DC), fuse type (Cartridge, Glass), response time (Fast Blow), package format (3AB, 3AG, 1/4" x 1-1/4"), mounting type (Through Hole), breaking capacity (100 A), melting I²t (45.9), operating temperature range (-55°C ~ 125°C), and DC cold resistance (0.035 Ohms). Both carry CSA and UL approvals.

Q: Are there any differences in compliance status between these parts?

A: The AGC-V-3-R is RoHS Compliant. The BK/AGC-V-3-R is ROHS3 Compliant with REACH Unaffected status. Both meet regulatory requirements for circuit protection applications. Selection should be based on specific application compliance requirements.

Q: What is the significance of the "BK/" prefix in the BK/AGC-V-3-R part number?

A: The BK/ prefix is part of the manufacturer's part numbering scheme. It does not affect the electrical or mechanical specifications of the fuse. The core specifications remain identical to the AGC-V-3-R.

Q: Can these fuses be used in both AC and DC applications?

A: Yes. Both the AGC-V-3-R and BK/AGC-V-3-R are rated for 250 V AC/DC operation, making them suitable for both alternating and direct current circuit protection applications.

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

A: The melting I²t value of 45.9 represents the thermal energy required to melt the fuse element. This parameter is critical for ensuring the fuse operates correctly within its designed circuit protection envelope and must match the application requirements.

Q: Are these fuses suitable for high-temperature environments?

A: Yes. Both fuses are rated for operating temperatures from -55°C to 125°C, providing functionality across a wide temperature range suitable for industrial and commercial applications.
