AGC-V-1/2-R Equivalent & Substitute Parts

Part Overview

The AGC-V-1/2-R is a 500 mA, 250 V AC/DC fast-blow glass cartridge fuse manufactured by Eaton - Electronics Division. This component is classified as obsolete, which necessitates identification of active equivalent alternatives for ongoing circuit protection applications. The fuse is designed for through-hole mounting in 3AB and 3AG package configurations with axial lead geometry (1/4" x 1-1/4").

Substitute Part Grouping Explanation

Substitution of the AGC-V-1/2-R is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Substitution Parameters:

  • Current Rating: 500 mA (exact match required)
  • Voltage Rating (AC): 250 V (exact match required)
  • Response Time: Fast Blow (exact match required)
  • Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (Axial) (exact match required)
  • Breaking Capacity @ Rated Voltage: 35 A (exact match required)
  • Melting I²t: 0.385 (exact match required)
  • Operating Temperature Range: -55°C ~ 125°C (exact match required)
  • DC Cold Resistance: 0.483 Ohms (exact match required)

Two substitute parts meet these criteria: BK/AGC-V-1/2-R and BK/AGC-V-1/2. Both are manufactured by Eaton - Electronics Division and maintain identical electrical and mechanical specifications to the main part number.

Engineering Selection Recommendations

BK/AGC-V-1/2-R is the primary substitute for AGC-V-1/2-R. This part number is in active production status and maintains complete electrical and mechanical equivalence. BK/AGC-V-1/2-R carries ROHS3 compliance and REACH unaffected status, providing enhanced regulatory alignment for new designs and procurement cycles.

BK/AGC-V-1/2 is a secondary substitute option. This part number is also in active production and maintains identical electrical and mechanical specifications. However, BK/AGC-V-1/2 is classified as RoHS non-compliant, which may restrict its use in applications subject to RoHS3 regulatory requirements.

Selection between the two active substitutes should be based on regulatory compliance requirements of the end application. For applications requiring RoHS3 compliance, BK/AGC-V-1/2-R is the appropriate choice. For applications without RoHS3 constraints, either substitute is functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can BK/AGC-V-1/2-R be used as a direct replacement for AGC-V-1/2-R?

A: Yes. BK/AGC-V-1/2-R is electrically and mechanically equivalent to AGC-V-1/2-R across all critical parameters: 500 mA current rating, 250 V AC voltage rating, fast-blow response time, 3AB/3AG package configuration, 35 A breaking capacity, 0.385 melting I²t, -55°C to 125°C operating temperature range, and 0.483 Ohms DC cold resistance. Both parts are manufactured by Eaton - Electronics Division and carry CSA and UL approvals.

Q: What is the difference between BK/AGC-V-1/2-R and BK/AGC-V-1/2?

A: Both parts are electrically and mechanically identical. The primary difference is regulatory compliance status. BK/AGC-V-1/2-R is ROHS3 compliant and REACH unaffected. BK/AGC-V-1/2 is RoHS non-compliant. Selection depends on whether the application requires RoHS3 certification.

Q: Are the physical dimensions identical across all three part numbers?

A: Yes. All three part numbers share identical physical dimensions: 0.266" diameter x 1.292" length (6.76 mm x 32.82 mm). All are configured for through-hole mounting with axial lead geometry in the 3AB and 3AG package standard.

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

A: Yes. All three part numbers are rated for 250 V AC/DC operation. The 500 mA current rating and 35 A breaking capacity apply to both AC and DC applications within the specified voltage range.

Q: Why is AGC-V-1/2-R classified as obsolete?

A: AGC-V-1/2-R is no longer in active production. Active equivalent alternatives (BK/AGC-V-1/2-R and BK/AGC-V-1/2) are available from the same manufacturer with identical specifications and improved regulatory compliance options.
