BK/AGC-2 Glass Cartridge Fuse Equivalent & Substitute Parts

Part Overview

The BK/AGC-2 is a 2 A, 250 V AC/DC fast-blow glass cartridge fuse manufactured by Eaton - Electronics Division. This fuse is designed for use in 3AB and 3AG holders with dimensions of 1/4" x 1-1/4" (6.35mm x 31.75mm). The BK/AGC-2 carries an obsolete product status, which necessitates identification of active equivalent and substitute parts to maintain circuit protection functionality in applications requiring this fuse specification.

Engineering Selection Recommendations

Primary Recommendation - Direct Eaton Substitutes:

The AGC-2-R, BK/AGC-2-R, BK/AGC-2RR, and BK/AGC-2RX are direct active substitutes from Eaton - Electronics Division. These parts maintain identical electrical and mechanical specifications to the obsolete BK/AGC-2. Selection among these Eaton variants should prioritize parts with ROHS3 compliance (AGC-2-R, BK/AGC-2-R, BK/AGC-2RR) for applications subject to RoHS regulations. All Eaton substitutes carry CSA and UL approval certifications.

Secondary Recommendation - Littelfuse Substitutes:

The 0312002.HXP, 0312002.MXP, and 0312002.VXP from Littelfuse Inc. are parametrically equivalent alternatives. These parts meet all electrical and mechanical requirements and carry expanded approval certifications including CE, CSA, KC, PSE, and UL. Littelfuse substitutes are ROHS3 compliant and REACH unaffected. Selection of Littelfuse alternatives is appropriate when supply availability or cost considerations favor cross-manufacturer sourcing.

Compliance Considerations:

For new designs or applications requiring RoHS compliance, AGC-2-R, BK/AGC-2-R, BK/AGC-2RR, 0312002.HXP, 0312002.MXP, and 0312002.VXP all satisfy ROHS3 requirements. The BK-AGC-B-2-R and BK/AGC-2RX do not specify RoHS status and should be evaluated against specific regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can I directly replace BK/AGC-2 with AGC-2-R?

A: Yes. AGC-2-R is an active direct substitute from Eaton - Electronics Division with identical electrical specifications (2 A, 250 V AC, fast-blow response) and mechanical compatibility (3AB, 3AG holder, 1/4" x 1-1/4" dimensions). AGC-2-R carries ROHS3 compliance, making it suitable for applications with RoHS requirements.

Q: What is the difference between Eaton and Littelfuse substitutes?

A: Both manufacturers provide parametrically equivalent 2 A, 250 V AC fast-blow glass cartridge fuses in 3AB/3AG packages. Eaton substitutes (AGC-2-R, BK/AGC-2-R, BK/AGC-2RR, BK/AGC-2RX) are direct product line continuations. Littelfuse substitutes (0312002.HXP, 0312002.MXP, 0312002.VXP) offer cross-manufacturer compatibility with expanded international certifications (CE, KC, PSE in addition to CSA, UL).

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

A: Yes. All substitute parts listed are specified for 3AB and 3AG holder compatibility with identical dimensions of 0.250" diameter x 1.250" length (6.35mm x 31.75mm). Physical and electrical compatibility is maintained across all substitutes.

Q: Which substitute should I select for RoHS-compliant applications?

A: AGC-2-R, BK/AGC-2-R, BK/AGC-2RR, 0312002.HXP, 0312002.MXP, and 0312002.VXP all carry ROHS3 compliance certification. BK-AGC-B-2-R and BK/AGC-2RX do not specify RoHS status and should not be selected for applications with explicit RoHS requirements.

Q: What is the breaking capacity specification and why does it matter?

A: Breaking capacity is 100 A at rated voltage for all substitute parts. This specification indicates the maximum fault current the fuse can safely interrupt without rupturing the fuse element or holder. All substitutes maintain this 100 A breaking capacity, ensuring equivalent circuit protection performance.

Q: Can I use these fuses in both AC and DC applications?

A: The specifications indicate 250 V AC rating. DC application compatibility is not explicitly stated in the provided parameters. Consult application-specific requirements and manufacturer datasheets for DC circuit applications.
