SCHURTER 7022.0660 Ceramic Fuse - Equivalent & Substitute Parts

Part Overview

The SCHURTER 7022.0660 is a 4 A, 500 V AC/DC ceramic cartridge fuse designed for fast-blow applications. This component requires a compatible holder (3AB, 3AG format) and is currently active in production with 1008 units in stock. Substitute parts are identified when equivalent electrical ratings, mechanical dimensions, and package specifications align with the original component requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 7022.0660 is determined by the following criteria:

• Current Rating: 4 A (exact match required)
• Voltage Rating (AC): 500 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)
• Mounting Type: Requires Holder (exact match required)
• RoHS Compliance: ROHS3 Compliant (required for regulatory alignment)

The Littelfuse 23114000029 meets all substitution criteria across electrical ratings, fuse characteristics, package specifications, and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Both the SCHURTER 7022.0660 and Littelfuse 23114000029 are active products with ROHS3 compliance and EAR99 export classification. Selection between these components should be based on:

• Availability: SCHURTER 7022.0660 has 1008 units in stock; Littelfuse 23114000029 has 769 units in stock
• Dimensional tolerance: Both components fit the 3AB, 3AG holder format with negligible dimensional variation (0.002" diameter difference, 0.008" length difference)
• Regulatory alignment: Both components meet ROHS3 and REACH Unaffected requirements

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse 23114000029 replace the SCHURTER 7022.0660 in existing designs?

A: Yes. Both components share identical electrical ratings (4 A, 500 V AC/DC), fuse type (ceramic cartridge), response time (fast blow), and package specification (3AB, 3AG, 1/4" x 1-1/4"). Dimensional differences are within typical holder tolerances.

Q: What are the key parameters that determine substitution eligibility?

A: Current rating, voltage rating, fuse type, response time, package format, and mounting type must match exactly. Both components meet these criteria.

Q: Are there compliance differences between these components?

A: Both components are ROHS3 compliant, REACH Unaffected, and classified as EAR99. No compliance barriers exist for substitution.

Q: Do these fuses require specific holders?

A: Yes. Both components require 3AB or 3AG format holders. The holder must be selected separately based on circuit requirements.

Q: What is the difference in breaking capacity between these parts?

A: The SCHURTER 7022.0660 has a breaking capacity of 150 kA at rated voltage, while the Littelfuse 23114000029 has 1 kA. This difference reflects different design specifications but does not affect substitution eligibility for standard 4 A, 500 V applications.
