BK/AGC-V-5 Equivalent & Substitute Parts

Part Overview

The BK/AGC-V-5 is a 5 A, 250 V AC/DC fast-blow glass cartridge fuse manufactured by Eaton - Electronics Division. This through-hole component operates within the temperature range of -55°C to 125°C and is designed for applications requiring fast-response overcurrent protection in 3AB, 3AG form factor (1/4" x 1-1/4" axial). The part maintains active product status with 755 units in current inventory. Substitute parts are identified when equivalent electrical characteristics, mechanical dimensions, and approval certifications align with the original specification, enabling direct circuit board replacement without design modification.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BK/AGC-V-5 are classified based on strict electrical and mechanical parameter alignment. The substitution logic requires matching the following critical parameters:

• Current Rating: 5 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: 200 A
• Operating Temperature Range: -55°C ~ 125°C
• Approval Agencies: CSA, UL (minimum requirement)

Two substitute parts meet these criteria: BK/AGC-V-5-R (Eaton - Electronics Division, bulk packaging) and 0318005.MXP (Littelfuse Inc., bulk packaging). Both components satisfy all mandatory electrical and mechanical specifications for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

BK/AGC-V-5-R (Eaton - Electronics Division): This substitute maintains identical electrical and mechanical specifications to the original BK/AGC-V-5, with the primary distinction being bulk packaging and RoHS3 compliance status. Both parts are manufactured by Eaton and hold active product status with CSA and UL approvals. The BK/AGC-V-5-R provides 1104 units in inventory compared to 755 units for the original part, supporting supply chain continuity.

0318005.MXP (Littelfuse Inc.): This substitute meets all critical electrical and mechanical parameters with CSA and UL approvals plus additional certifications (CE, KC, PSE). The part demonstrates RoHS3 compliance and REACH unaffected status. Inventory availability is 2780 units. Minor dimensional variation exists (0.275" diameter versus 0.266"), and melting I²t differs (50 versus 131.5), reflecting manufacturer-specific design characteristics within the 3AB, 3AG form factor tolerance band. Both parameters remain within acceptable substitution criteria for the specified application.

Frequently Asked Questions (FAQ)

Q: Can BK/AGC-V-5-R directly replace BK/AGC-V-5 in existing circuit boards?

A: Yes. BK/AGC-V-5-R is a direct substitute with identical current rating (5 A), voltage rating (250 V), fuse type (cartridge, glass), response time (fast blow), package dimensions (3AB, 3AG, 1/4" x 1-1/4"), mounting type (through hole), and breaking capacity (200 A). Both parts are manufactured by Eaton and hold CSA and UL approvals.

Q: What is the difference between BK/AGC-V-5 and BK/AGC-V-5-R?

A: The primary differences are packaging format (standard versus bulk) and RoHS compliance status (non-compliant versus RoHS3 compliant). Electrical and mechanical specifications are identical. The BK/AGC-V-5-R offers higher inventory availability (1104 units versus 755 units).

Q: Can 0318005.MXP replace BK/AGC-V-5 in all applications?

A: 0318005.MXP meets all mandatory electrical specifications (5 A, 250 V AC, fast-blow cartridge fuse, 200 A breaking capacity) and mechanical requirements (3AB, 3AG form factor, through-hole mounting). Minor dimensional variation (0.275" diameter versus 0.266") and melting I²t difference (50 versus 131.5) exist but remain within acceptable tolerance for the specified form factor. Littelfuse manufacturing holds CSA and UL approvals plus additional certifications (CE, KC, PSE).

Q: What approval certifications are required for substitution?

A: Minimum required certifications are CSA and UL, matching the original BK/AGC-V-5 specification. Both substitute parts satisfy this requirement. 0318005.MXP provides additional certifications (CE, KC, PSE) for expanded geographic compliance.

Q: Are there RoHS compliance considerations for substitution?

A: BK/AGC-V-5 is RoHS non-compliant. BK/AGC-V-5-R and 0318005.MXP are both RoHS3 compliant. If RoHS compliance is required for the end application, either substitute part is suitable. If RoHS non-compliance is specified, only BK/AGC-V-5 meets the requirement.

Q: What is the operating temperature range for all three parts?

A: All three parts operate within -55°C to 125°C, ensuring thermal compatibility across substitute selections.
