SCHURTER 7010.2610 Equivalent & Substitute Parts

Part Overview

The SCHURTER 7010.2610 is a 6.3 A, 125 V AC/DC fast-blow glass cartridge fuse in a non-standard cartridge format requiring a dedicated holder. This part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 7010.2610 is based on the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Current Rating: 6.3 A (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Fast Blow (exact match required)
• Mounting Type: Requires Holder (exact match required)

Secondary Compatibility Factors:

• Voltage Rating: The substitute must meet or exceed the 125 V AC requirement
• Physical Dimensions: Substitute must be compatible with existing holder assemblies or documented as a direct mechanical replacement
• Breaking Capacity: Must be sufficient for the application circuit

The Littelfuse 021706.3HXP meets the primary electrical criteria (6.3 A, fast-blow, glass cartridge) and exceeds the voltage rating (250 V AC vs. 125 V AC). However, the physical dimensions differ (5mm x 20mm vs. 4.70mm x 16.00mm non-standard), requiring verification of mechanical compatibility with the original holder assembly.

Parameter Comparison

Engineering Selection Recommendations

The Littelfuse 021706.3HXP is the identified substitute for the obsolete SCHURTER 7010.2610 based on matching electrical specifications (6.3 A, fast-blow, glass cartridge construction). Both parts are ROHS3 compliant and REACH unaffected.

Electrical Compatibility: The Littelfuse part exceeds the voltage rating requirement (250 V AC vs. 125 V AC), providing additional safety margin. The higher breaking capacity (63 A vs. 35 A) and melting I²t value (62.465 vs. 31) indicate enhanced performance characteristics suitable for the same circuit protection application.

Mechanical Compatibility: The dimensional difference between the non-standard SCHURTER cartridge (4.70mm x 16.00mm) and the standard 5mm x 20mm Littelfuse cartridge requires physical verification. The substitute may require a different holder assembly or adapter, depending on the original equipment design.

Regulatory & Compliance: The Littelfuse part carries multiple international approvals (BSI, CCC, CE, CSA, KC, PSE, SEMKO, UR, VDE), exceeding the compliance profile of the original part.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse 021706.3HXP be used as a direct replacement without modification?

A: Electrical substitution is valid based on current rating, voltage rating, and response time. However, mechanical compatibility depends on the holder assembly design. The dimensional difference (5mm x 20mm vs. 4.70mm x 16.00mm non-standard) must be confirmed before installation.

Q: Why is the voltage rating higher on the substitute part?

A: The Littelfuse 021706.3HXP is rated for 250 V AC, which exceeds the 125 V AC requirement of the original SCHURTER part. This higher rating does not affect compatibility in 125 V AC circuits and provides additional safety margin.

Q: What is the significance of the different melting I²t values?

A: The melting I²t value (62.465 for Littelfuse vs. 31 for SCHURTER) indicates the thermal energy required to melt the fuse element. The higher value on the substitute reflects its larger physical size and does not affect its fast-blow response characteristic at the rated 6.3 A current.

Q: Are both parts RoHS compliant?

A: Yes, both the SCHURTER 7010.2610 and Littelfuse 021706.3HXP are ROHS3 compliant and REACH unaffected.

Q: What should be verified before implementing this substitution?

A: Mechanical fit within the existing holder assembly is the primary consideration. The physical dimensions differ, so confirmation that the 5mm x 20mm cartridge is compatible with the original holder design is required before deployment.
