Engineering Selection Recommendations

Eaton ABC Series (Eaton - Electronics Division):

The ABC-15-R, BK/ABC-15-R, BK/ABC-15DD-R, and BK1/ABC-15AX-R are direct functional equivalents to the BK/ABC-15KK. All maintain identical electrical specifications including 15 A current rating, 250 V AC / 125 V DC voltage ratings, and 750A AC / 10kA DC breaking capacity. These variants are ROHS3 compliant, addressing environmental compliance requirements. The BK/ABC-15-R offers the highest inventory availability at 3,845 pieces.

Eaton GBB Series (Eaton - Electronics Division):

The BK/GBB-15-R meets all mandatory electrical parameters but features a different series designation. It maintains the same current and voltage ratings with 10kA AC breaking capacity. DC cold resistance is lower at 0.00472 Ohms compared to 0.00553 Ohms in the ABC series. This part is ROHS3 compliant and carries CSA and UR approvals.

Littelfuse 314 Series (Littelfuse Inc.):

The 0314015.HXP, 0314015.MXANP, 0314015.MXP, and 0314015.VXP are cross-manufacturer equivalents from Littelfuse Inc. All four maintain identical electrical specifications with 15 A current rating and 250 V AC / 125 V DC voltage ratings. These parts feature a melting I²t of 292 compared to 200.2 in Eaton parts, and DC cold resistance of 0.00505 Ohms. All are ROHS3 compliant with operating temperature range of -55°C to 125°C. The 0314015.MXANP offers the highest inventory at 4,560 pieces among Littelfuse options.

Selection Basis:

Selection among these substitutes should be based on:

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts as a direct replacement for BK/ABC-15KK?

A: Yes. All listed substitute parts meet the mandatory electrical and mechanical parameters: 15 A current rating, 250 V AC / 125 V DC voltage ratings, fast-blow response, ceramic cartridge construction, and 3AB/3AG holder compatibility with 0.250" x 1.250" dimensions. Physical installation and electrical function are identical.

Q: What is the difference between Eaton ABC series and Littelfuse 314 series substitutes?

A: Both series meet all mandatory electrical specifications. The primary differences are manufacturer origin and secondary parameters. Littelfuse 314 series parts have a melting I²t of 292 versus 200.2 for Eaton ABC series, and DC cold resistance of 0.00505 Ohms versus 0.00553 Ohms. Littelfuse parts include operating temperature specification (-55°C to 125°C) while Eaton parts do not specify this parameter. Both are ROHS3 compliant.

Q: Why does BK/GBB-15-R show different breaking capacity specifications?

A: The BK/GBB-15-R specifies 10kA breaking capacity for both AC and DC, whereas most ABC series parts specify 750A AC and 10kA DC. This represents a design difference within the Eaton product line. The part remains functionally equivalent for the BK/ABC-15KK application as it meets or exceeds the breaking capacity requirements.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts listed are ROHS3 compliant. The original BK/ABC-15KK is noted as RoHS non-compliant. If RoHS compliance is required for your application, any of the substitute parts satisfy this requirement.

Q: Which substitute part has the best availability?

A: The 0314015.MXANP from Littelfuse Inc. has the highest inventory at 4,560 pieces. Among Eaton parts, BK/ABC-15-R offers 3,845 pieces in stock.

Q: Do I need to change the fuse holder when switching to a substitute part?

A: No. All substitute parts use the same 3AB, 3AG holder standard with identical 0.250" diameter by 1.250" length dimensions. Existing holders are compatible with all listed substitutes.

Q: What approval agencies certify these substitute parts?

A: Eaton ABC series parts carry CSA and UL approvals. The BK/GBB-15-R carries CSA and UR approvals. Littelfuse 314 series parts carry multiple certifications including CE, CSA, K-MARK, UL, KC, and PSE depending on the specific part number variant.
