Equivalent & Substitute Parts for ABC-1-R Ceramic Cartridge Fuse

Part Overview

The ABC-1-R is a 1 A ceramic cartridge fuse manufactured by Eaton - Electronics Division, rated for 250 V AC and 125 V DC operation. This fast-blow fuse is designed for use with 3AB, 3AG holders and measures 0.250" diameter by 1.250" length (6.35mm x 31.75mm). The part maintains Active product status with CSA and UL approval certifications. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same fuse category, package format, and voltage/current ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ABC-1-R are classified based on strict equivalence of electrical and mechanical parameters. The substitution logic is based on the following criteria:

Primary Equivalence Parameters:

• Current Rating: 1 A (exact match required)
• Voltage Rating - AC: 250 V (exact match required)
• Voltage Rating - DC: 125 V (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Size / Dimension: 0.250" Dia x 1.250" L (exact match required)

Secondary Considerations:

• Breaking Capacity @ Rated Voltage (may vary within acceptable ranges)
• DC Cold Resistance (minor variations acceptable)
• Melting I²t (may vary)
• Approval Agencies (CSA, UL, CE, PSE certifications)

All identified substitutes maintain identical current, voltage, fuse type, response time, and physical package specifications as the ABC-1-R.

Parameter Comparison

Engineering Selection Recommendations

Direct Manufacturer Equivalent: BK/ABC-1-R is the direct equivalent from Eaton - Electronics Division. This part maintains identical electrical specifications, breaking capacity, DC cold resistance, and melting I²t characteristics as the ABC-1-R. Both parts carry Active product status with CSA and UL certifications. Selection of BK/ABC-1-R presents no technical differentiation from the primary part.

Parametric Equivalents - Eaton Series: BK/GBB-1-R is a parametric equivalent from Eaton - Electronics Division within the GBB series. This part matches all critical electrical parameters (1 A, 250 V AC, 125 V DC, Fast Blow) and physical dimensions. The breaking capacity is specified at 10 kA DC only, with DC cold resistance of 0.1775 Ohms. Both parts maintain Active status with CSA certification; however, BK/GBB-1-R carries UR approval instead of UL. Selection requires verification of approval agency requirements for the application.

Parametric Equivalents - Littelfuse Series: 0314001.HXP and 0314001.MXP are parametric equivalents from Littelfuse Inc. within the 314 series. Both parts match all critical electrical parameters and physical dimensions. These parts feature higher breaking capacity (100 A AC, 10 kA DC) and maintain Active product status. Certifications include CE, CSA, PSE, and UL. DC cold resistance is 0.189 Ohms with melting I²t of 0.69. Operating temperature range is specified as -55°C to 125°C.

Obsolete Part - Not Recommended: 0332001.HXP from Littelfuse Inc. carries Obsolete product status and is not recommended for new designs or applications requiring long-term availability. This part is listed for reference only in legacy system documentation.

Frequently Asked Questions (FAQ)

Q: Can BK/ABC-1-R be used as a direct replacement for ABC-1-R? A: Yes. BK/ABC-1-R is manufactured by the same company (Eaton - Electronics Division) and maintains identical electrical specifications, breaking capacity, resistance, and melting I²t values. Both parts are Active status with CSA and UL certifications.

Q: What is the difference between ABC-1-R and BK/GBB-1-R? A: Both parts share identical current rating (1 A), voltage ratings (250 V AC, 125 V DC), fuse type (ceramic cartridge), response time (fast blow), and physical dimensions (0.250" x 1.250"). The BK/GBB-1-R has slightly lower DC cold resistance (0.1775 Ω vs. 0.195 Ω) and carries UR certification instead of UL. Breaking capacity for AC is not specified for BK/GBB-1-R.

Q: Are Littelfuse 0314001.HXP and 0314001.MXP interchangeable with ABC-1-R? A: Both Littelfuse parts are parametric equivalents with matching current, voltage, fuse type, response time, and physical package specifications. They feature higher breaking capacity (100 A AC vs. 35 A AC) and broader temperature range (-55°C to 125°C). Both carry CE, CSA, PSE, and UL certifications. Substitution is technically valid based on electrical and mechanical parameters.

Q: Why is 0332001.HXP listed if it is obsolete? A: 0332001.HXP is included for reference in legacy system documentation and component traceability. This part carries Obsolete product status and should not be selected for new applications or designs requiring long-term component availability.

Q: What holder types are compatible with these fuses? A: All listed parts require 3AB or 3AG holder types. Physical dimensions are standardized at 0.250" diameter by 1.250" length (6.35mm x 31.75mm) across all substitute parts.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed parts maintain ROHS3 Compliant status. All parts are also REACH Unaffected and classified under ECCN EAR99.

Q: What is the inventory status for these parts? A: ABC-1-R: 899 Pcs; BK/ABC-1-R: 1326 Pcs; BK/GBB-1-R: 991 Pcs; 0314001.HXP: 1419 Pcs; 0314001.MXP: 1953 Pcs; 0332001.HXP: 736 Pcs. All parts are listed as New Original In Stock.
