BK-AGC-B-2-R Equivalent & Substitute Parts

Part Overview

The BK-AGC-B-2-R is a 2 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 dimensions of 0.250" diameter by 1.250" length (6.35 mm × 31.75 mm). The part maintains active product status and is currently in stock with 718 pieces available.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across manufacturers. Alternative part numbers from Eaton and Littelfuse are available to support procurement flexibility, inventory management, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BK-AGC-B-2-R is determined by strict equivalence across the following parameters:

Critical Electrical Parameters:

• Current Rating: 2 A
• Voltage Rating (AC): 250 V
• Response Time: Fast Blow
• Breaking Capacity @ Rated Voltage: 100 A

Critical Mechanical Parameters:

• Fuse Type: Cartridge, Glass
• Package / Case: 3AB, 3AG
• Size / Dimension: 0.250" Dia × 1.250" L (6.35 mm × 31.75 mm)
• Mounting Type: Requires Holder

Environmental Parameters:

• Operating Temperature Range: -55°C ~ 125°C

All identified substitute parts maintain these parameters without deviation. Variations in melting I²t and DC cold resistance do not preclude substitution when all critical parameters are matched. Substitute parts from both Eaton and Littelfuse manufacturers are qualified based on identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and are manufactured by established component suppliers. Selection among equivalent parts is based on availability, procurement lead time, and inventory position.

Eaton Equivalents (AGC-2-R, BK/AGC-2-R): These parts are direct Eaton alternatives to the BK-AGC-B-2-R. Both maintain identical electrical and mechanical specifications with CSA and UL approval. Current inventory levels are 1341 and 1461 pieces respectively, providing adequate supply.

Littelfuse Equivalents (0312002.HXP, 0312002.MXP, 0312002.VXP): These parts are functionally equivalent with expanded approval agency coverage including CE, KC, and PSE certifications in addition to CSA and UL. Littelfuse parts carry higher inventory levels (3869, 8793, and 1063 pieces respectively), supporting extended availability.

All substitute parts are RoHS3 compliant and REACH unaffected where specified. Selection should be based on supply chain requirements, cost considerations, and existing qualification status within the application.

Frequently Asked Questions (FAQ)

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

A: Yes. AGC-2-R is a parametric equivalent with identical current rating (2 A), voltage rating (250 V AC), response time (fast blow), package designation (3AB, 3AG), physical dimensions (0.250" × 1.250"), breaking capacity (100 A), and operating temperature range (-55°C ~ 125°C). Both are manufactured by Eaton and carry CSA and UL approval.

Q: What is the difference between Eaton and Littelfuse substitute parts?

A: Eaton parts (AGC-2-R, BK/AGC-2-R) and Littelfuse parts (0312002.HXP, 0312002.MXP, 0312002.VXP) are electrically and mechanically equivalent. Littelfuse parts carry additional approval certifications (CE, KC, PSE) beyond the CSA and UL certifications common to all parts. Melting I²t values differ (Eaton: 17.52; Littelfuse: 5.2) and DC cold resistance varies slightly (Eaton: 0.063 Ohms; Littelfuse: 0.0704 Ohms), but these variations do not affect substitution eligibility.

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

A: Yes. All substitute parts are specified for 3AB and 3AG fuse holder compatibility with identical physical dimensions of 0.250" diameter by 1.250" length (6.35 mm × 31.75 mm). Physical interchangeability is confirmed across all listed parts.

Q: What approval certifications apply to each substitute part?

A: BK-AGC-B-2-R, AGC-2-R, and BK/AGC-2-R carry CSA and UL approval. Littelfuse parts (0312002.HXP, 0312002.MXP, 0312002.VXP) carry CE, CSA, KC, PSE, and UL approval. All parts meet the minimum approval requirements for standard industrial applications.

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

A: The specifications indicate 250 V AC rating. All parts are designated as 250 V AC/DC fuse cartridges. Application in DC circuits requires verification that the DC voltage does not exceed the AC voltage rating and that the circuit breaking requirements are satisfied.

Q: What is the difference between the Littelfuse part number variants (HXP, MXP, VXP)?

A: All three Littelfuse variants (0312002.HXP, 0312002.MXP, 0312002.VXP) maintain identical electrical and mechanical parameters. Differences in part number designation reflect internal Littelfuse product line categorization but do not affect functional equivalence or substitution eligibility.
