SCHURTER 7020.8530 Equivalent & Substitute Parts

Part Overview

The SCHURTER 7020.8530 is a 2A ceramic cartridge fuse rated for 500VAC and 250VDC operation. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing system maintenance and new designs. The fuse features fast-blow response characteristics and requires a dedicated holder for installation. Due to its discontinued status, sourcing equivalent alternatives from active product lines is essential for system continuity.

Key Parameters

Substitute Part Grouping Explanation

The Littelfuse KLNR002.T is identified as a functional equivalent based on the following substitution criteria:

Matching Parameters:

• Current Rating: 2A (identical)
• Fuse Type: Cartridge (identical)
• Response Time: Fast Blow (identical)
• Mounting Type: Requires Holder (identical)
• Package / Case: Cartridge, Non-Standard (identical)

Voltage Consideration: The KLNR002.T operates at 250VAC/125VDC, which represents a lower voltage rating than the original 7020.8530 (500VAC/250VDC). This substitution is valid only for applications where the actual operating voltage does not exceed 250VAC or 125VDC. The substitute part must not be used in circuits designed for the full 500VAC or 250VDC capability of the original component.

Breaking Capacity: The KLNR002.T provides enhanced breaking capacity (200kA AC, 20kA DC) compared to the original part (100kA AC, 10kA DC), offering improved fault protection margins.

Parameter Comparison

Engineering Selection Recommendations

The Littelfuse KLNR002.T is an active product with current manufacturing status and holds multiple regulatory certifications (CE, CSA, UL), providing advantages over the obsolete SCHURTER 7020.8530. The substitute part achieves ROHS3 compliance, addressing environmental regulatory requirements that the original part does not meet.

Selection of the KLNR002.T requires verification that the application circuit operates within the lower voltage ratings (250VAC/125VDC maximum). The marginal dimensional differences (0.012" diameter increase, 0.031" length increase) must be confirmed compatible with existing holder assemblies. The enhanced breaking capacity of the substitute part provides additional safety margin in fault conditions.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse KLNR002.T directly replace the SCHURTER 7020.8530 in all applications?

A: Direct replacement is valid only for circuits operating at or below 250VAC and 125VDC. Applications requiring the full 500VAC or 250VDC rating of the original part cannot use this substitute.

Q: What are the dimensional compatibility considerations?

A: The KLNR002.T is slightly larger (0.563" Dia x 2.000" L versus 0.551" Dia x 1.969" L). Physical fit within the existing holder assembly must be confirmed before installation.

Q: Does the substitute part meet current regulatory standards?

A: Yes. The KLNR002.T is ROHS3 compliant and holds CE, CSA, and UL certifications, meeting current environmental and safety standards that the obsolete original part does not.

Q: How do the breaking capacities compare?

A: The KLNR002.T provides 200kA AC and 20kA DC breaking capacity, compared to 100kA AC and 10kA DC for the original part. This represents a 2x improvement in fault protection capability.

Q: What is the current availability status of each part?

A: The SCHURTER 7020.8530 is obsolete with limited remaining inventory (992 pcs). The Littelfuse KLNR002.T is an active product with current manufacturing and available inventory (790 pcs).
