BK/AGC-V-2 Equivalent & Substitute Parts

Part Overview

The BK/AGC-V-2 is a 2 A 250 V AC/DC fast-blow glass cartridge fuse in the 3AB, 3AG form factor (1/4" x 1-1/4" axial). Manufactured by Eaton - Electronics Division, this component is classified as obsolete. Due to its obsolete status, equivalent and substitute parts are necessary for ongoing system maintenance, repairs, and new designs requiring compatible fuse protection. Active alternatives with identical or equivalent electrical and mechanical parameters are available from both Eaton and third-party manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BK/AGC-V-2 is determined by strict equivalence across the following critical parameters:

• Current Rating: 2 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (Axial) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Breaking Capacity @ Rated Voltage: 100 A (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

All substitute parts listed below meet these criteria. Variations in secondary parameters such as melting I²t, DC cold resistance, and dimensional tolerances are noted but do not preclude substitution when primary electrical and mechanical parameters align.

Engineering Selection Recommendations

Primary Recommendation: AGC-V-2-R or BK/AGC-V-2-R

Both AGC-V-2-R and BK/AGC-V-2-R are direct Eaton equivalents with identical electrical and mechanical specifications to the BK/AGC-V-2. These parts are active products with RoHS compliance, making them suitable for new designs and systems requiring environmental compliance. The BK/AGC-V-2-R variant is available in bulk packaging. Current inventory levels support immediate procurement.

Secondary Recommendation: BK/AGC-SV-2

The BK/AGC-SV-2 is an active Eaton product with identical core electrical and mechanical parameters. This part maintains the same melting I²t and DC cold resistance as the original BK/AGC-V-2. RoHS non-compliance status should be evaluated against system requirements.

Alternative Recommendation: 0318002.MXP

The 0318002.MXP from Littelfuse Inc. meets all critical electrical and mechanical substitution criteria. This part is active and ROHS3 compliant. The Littelfuse component carries expanded approval certifications (CE, KC, PSE in addition to CSA and UL), providing broader regulatory acceptance. Dimensional tolerances differ slightly (0.275" Dia x 1.288" L versus 0.266" Dia x 1.292" L), and melting I²t is lower (5.2 versus 17.52). These variations remain within acceptable substitution parameters for the 3AB, 3AG form factor.

Frequently Asked Questions (FAQ)

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

A: Yes. AGC-V-2-R is a direct equivalent with identical current rating (2 A), voltage rating (250 V AC), fuse type (cartridge, glass), response time (fast blow), package (3AB, 3AG, 1/4" x 1-1/4"), mounting type (through hole), breaking capacity (100 A), and operating temperature range (-55°C ~ 125°C). The primary difference is product status: AGC-V-2-R is active while BK/AGC-V-2 is obsolete.

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

A: Both parts are Eaton equivalents with identical electrical and mechanical specifications. The primary distinction is packaging: AGC-V-2-R is available in standard packaging, while BK/AGC-V-2-R is supplied in bulk packaging. Both are RoHS compliant and active products.

Q: Is the Littelfuse 0318002.MXP a suitable substitute?

A: Yes. The 0318002.MXP meets all critical substitution parameters: 2 A current rating, 250 V AC voltage rating, cartridge glass fuse type, fast-blow response, 3AB/3AG package, through-hole mounting, 100 A breaking capacity, and -55°C ~ 125°C operating temperature. The part is active and ROHS3 compliant. Minor dimensional variations (0.275" Dia x 1.288" L) and lower melting I²t (5.2) do not preclude substitution within the 3AB, 3AG form factor specification.

Q: Why does the Littelfuse part have a different melting I²t value?

A: Melting I²t is a secondary parameter that reflects thermal characteristics within the fuse element. While the Littelfuse 0318002.MXP has a lower melting I²t (5.2 versus 17.52), both parts maintain identical current rating, voltage rating, and response time classifications. The difference reflects design variations between manufacturers but does not affect substitution eligibility for applications requiring 2 A, 250 V AC fast-blow protection.

Q: Are there RoHS compliance considerations for substitution?

A: Yes. The original BK/AGC-V-2 is RoHS non-compliant. Active substitutes AGC-V-2-R and BK/AGC-V-2-R are RoHS compliant, making them preferable for new designs and systems subject to environmental regulations. The Littelfuse 0318002.MXP is ROHS3 compliant. If RoHS compliance is not a requirement, BK/AGC-SV-2 (RoHS non-compliant) remains a valid equivalent.

Q: Can these fuses be used interchangeably in existing equipment?

A: All listed substitutes are mechanically and electrically compatible with the BK/AGC-V-2 within the 3AB, 3AG through-hole form factor. Dimensional tolerances are within acceptable ranges for standard fuse holders. Substitution is supported by matching current rating, voltage rating, response time, and breaking capacity specifications.

Q: What approval certifications should I verify?

A: The original BK/AGC-V-2 carries CSA and UL approvals. All Eaton substitutes (AGC-V-2-R, BK/AGC-V-2-R, BK/AGC-SV-2) maintain CSA and UL certifications. The Littelfuse 0318002.MXP carries expanded certifications: CE, CSA, KC, PSE, and UL. Verify that selected substitute certifications align with system and regional requirements.
