Equivalent & Substitute Parts for ABC-1/10-R Ceramic Cartridge Fuse

Part Overview

The ABC-1/10-R is a 100 mA, 250 V AC/DC ceramic cartridge fuse manufactured by Eaton - Electronics Division. This fast-blow fuse is designed for circuits requiring 3AB and 3AG holder compatibility with a 1/4" x 1-1/4" form factor. The part is currently active in production with 905 units in stock. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to supply constraints, design standardization, or application-specific voltage requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the ABC-1/10-R is based on the following criteria:

Mandatory Matching Parameters:

• Current Rating: 100 mA (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)
• Physical Dimensions: 0.250" Dia x 1.250" L (exact match required)
• Mounting Type: Requires Holder (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

Parameters Allowed to Exceed:

• Voltage Rating - AC: 250 V minimum (substitute may have higher rating)
• Approval Agency: CSA, UL minimum (substitute may have additional certifications)

The substitute part SCHURTER 7022.0500 meets all mandatory criteria and exceeds the voltage rating specification, making it electrically and mechanically compatible with the ABC-1/10-R in applications where higher voltage tolerance is acceptable.

Parameter Comparison

Engineering Selection Recommendations

ABC-1/10-R (Eaton) Selection Criteria:

• Primary choice when CSA and UL certifications are explicitly required by design specification or regulatory requirement
• Suitable for 250 V AC/DC circuits where voltage rating matches application exactly
• Recommended when design validation has been completed specifically for this part number

7022.0500 (SCHURTER) Selection Criteria:

• Acceptable substitute when circuit voltage does not exceed 500 V AC and UR certification meets application requirements
• Suitable for designs requiring higher voltage margin or when Eaton part is unavailable
• Both parts are ROHS3 compliant and support equivalent environmental standards
• Physical dimensions are within tolerance for standard 3AB/3AG holders

Certification Consideration: The ABC-1/10-R carries CSA and UL approvals, while the 7022.0500 carries UR approval. Selection between these parts must account for certification requirements specified in the end-application design documentation.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 7022.0500 be used as a direct replacement for the Eaton ABC-1/10-R?

A: The SCHURTER 7022.0500 is mechanically and electrically compatible with the ABC-1/10-R for applications operating at or below 250 V AC. Both parts share identical current rating (100 mA), fuse type (ceramic cartridge), response time (fast blow), and package specifications (3AB, 3AG, 1/4" x 1-1/4"). The substitute part exceeds the voltage specification at 500 V, which does not compromise compatibility in 250 V circuits. However, certification differences (UR vs. CSA/UL) must be evaluated against application requirements.

Q: What are the physical dimension tolerances between these parts?

A: The ABC-1/10-R measures 0.250" Dia x 1.250" L (6.35mm x 31.75mm). The SCHURTER 7022.0500 measures 0.250" Dia x 1.252" L (6.35mm x 31.80mm). The length difference of 0.002" (0.05mm) is within standard mechanical tolerance for cartridge fuse holders and does not affect holder compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both the ABC-1/10-R and SCHURTER 7022.0500 are ROHS3 compliant, meeting equivalent environmental and material restriction standards.

Q: What is the difference in approval agencies between these parts?

A: The ABC-1/10-R carries CSA and UL certifications. The SCHURTER 7022.0500 carries UR certification. These are different regulatory approval bodies. Selection must align with the certification requirements specified in the application design or regulatory framework.

Q: Can the higher voltage rating of the SCHURTER part affect circuit performance?

A: No. A fuse with a higher voltage rating (500 V vs. 250 V) does not alter the current-breaking characteristics or response time. Both parts are rated for 100 mA fast-blow operation. The higher voltage rating provides additional safety margin but does not change the fuse's protective function in a 250 V circuit.

Q: What holder types are compatible with both parts?

A: Both the ABC-1/10-R and SCHURTER 7022.0500 require standard 3AB and 3AG cartridge fuse holders. They are mechanically interchangeable in any holder designed for these specifications.
