Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ABC-30-R is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Current Rating: 30 A
• Voltage Rating - AC: 250 V
• Voltage Rating - DC: 125 V
• Fuse Type: Cartridge, Ceramic
• Response Time: Fast Blow
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (6.35mm x 31.75mm)
• Mounting Type: Requires Holder

All identified substitute parts meet these mandatory parameters. Variations in secondary parameters such as breaking capacity, melting I²t, DC cold resistance, and approval agency certifications do not disqualify substitution but are documented for engineering reference.

Parameter Comparison

Engineering Selection Recommendations

Direct Manufacturer Equivalents (Eaton - Electronics Division):

BK/ABC-30-R is a direct equivalent to ABC-30-R, sharing identical electrical specifications, breaking capacity, melting I²t, and DC cold resistance. Both parts carry CSA and UL certifications and are ROHS3 compliant. Selection between ABC-30-R and BK/ABC-30-R is based on inventory availability and procurement source.

Parametric Equivalent (Eaton - Electronics Division):

BK/GBB-30-R meets all mandatory electrical and mechanical parameters. This part differs in breaking capacity (10kA versus 200A AC / 400A DC) and carries CSA and UR certifications. The higher breaking capacity of BK/GBB-30-R provides enhanced protection margin in high-fault-current applications.

Cross-Manufacturer Equivalents (Littelfuse Inc.):

0314030.MXP and 0314030.HXP are functionally equivalent ceramic cartridge fuses from Littelfuse Inc. Both parts satisfy all mandatory parameters and carry expanded certifications including CE, K-MARK, PSE, and UL. These parts feature operating temperature specification (-55°C ~ 125°C), lower DC cold resistance (0.00182 Ohms), and higher melting I²t (2490). Both parts are ROHS3 compliant and REACH unaffected.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and active production status. Selection should account for application-specific certification requirements and geographic regulatory frameworks.

Frequently Asked Questions (FAQ)

Q: Can BK/ABC-30-R be used as a direct replacement for ABC-30-R?

A: Yes. BK/ABC-30-R is a direct manufacturer equivalent with identical current rating (30 A), voltage ratings (250 V AC / 125 V DC), fuse type (ceramic cartridge), response time (fast blow), package format (3AB, 3AG, 1/4" x 1-1/4"), and electrical characteristics (breaking capacity 200A AC / 400A DC, melting I²t 1429, DC cold resistance 0.002225 Ohms). Both parts are manufactured by Eaton and carry CSA and UL certifications.

Q: What is the difference between BK/GBB-30-R and ABC-30-R?

A: BK/GBB-30-R matches all mandatory electrical and mechanical parameters but features a higher breaking capacity of 10kA compared to ABC-30-R's 200A AC / 400A DC. This higher breaking capacity provides enhanced protection in applications with elevated fault current levels. BK/GBB-30-R carries CSA and UR certifications.

Q: Are Littelfuse 0314030.MXP and 0314030.HXP suitable replacements?

A: Yes. Both Littelfuse parts meet all mandatory substitution criteria: 30 A current rating, 250 V AC / 125 V DC voltage ratings, ceramic cartridge fuse type, fast-blow response, and 3AB/3AG package format. These parts feature lower DC cold resistance (0.00182 Ohms versus 0.002225 Ohms) and higher melting I²t (2490 versus 1429). Both carry CE, K-MARK, PSE, and UL certifications and include operating temperature specification (-55°C ~ 125°C).

Q: Do all substitute parts require the same holder?

A: Yes. All substitute parts use the 3AB, 3AG, 1/4" x 1-1/4" (6.35mm x 31.75mm) package format and require compatible fuse holders designed for this cartridge specification.

Q: What certifications apply to each substitute part?

A: ABC-30-R and BK/ABC-30-R carry CSA and UL certifications. BK/GBB-30-R carries CSA and UR certifications. Littelfuse parts 0314030.MXP and 0314030.HXP carry CE, K-MARK, PSE, and UL certifications. Application requirements determine which certification set is appropriate.

Q: Are all parts ROHS3 compliant?

A: Yes. All listed parts, including ABC-30-R, BK/ABC-30-R, BK/GBB-30-R, 0314030.MXP, and 0314030.HXP, are ROHS3 compliant.

Q: What is the inventory status for each part?

A: ABC-30-R: 879 pieces. BK/ABC-30-R: 2200 pieces. BK/GBB-30-R: 1002 pieces. 0314030.MXP: 3300 pieces. 0314030.HXP: 4000 pieces. All parts are listed as new original stock.
