Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Littelfuse 0262001.V are identified based on the following critical parameters:

• Current Rating: 1 A (exact match required)
• Voltage Rating: 125 V AC and 125 V DC (exact match required)
• Response Time: Fast Blow (exact match required)
• Mounting Type: Through Hole (exact match required)
• Fuse Type: Board Mount (Cartridge Style Excluded) (exact match required)
• RoHS Compliance: ROHS3 Compliant (compliance level match required)

The SCHURTER 0034.4221 meets all critical electrical parameters and compliance requirements, making it a valid substitute despite minor differences in physical dimensions and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

Both the Littelfuse 0262001.V and SCHURTER 0034.4221 are Active status products with ROHS3 compliance and REACH Unaffected status. Selection between these parts depends on application-specific requirements:

The Littelfuse 0262001.V is suitable for applications requiring extended operating temperature range (-55°C to 125°C) and higher breaking capacity (10 kA) with CSA, QPL, and UL certifications.

The SCHURTER 0034.4221 is suitable for applications within the -25°C to 85°C operating range with cURus certification and provides equivalent electrical performance for standard industrial applications.

Physical dimensions differ slightly between the two parts. Verify PCB layout compatibility before substitution.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 0034.4221 directly replace the Littelfuse 0262001.V?

A: Yes, for applications operating within -25°C to 85°C. Both parts share identical current rating (1 A), voltage rating (125 V AC/DC), response time (Fast Blow), and mounting type (Through Hole). Verify PCB footprint compatibility due to dimensional differences.

Q: What are the key differences between these substitute parts?

A: The primary differences are operating temperature range (Littelfuse: -55°C to 125°C; SCHURTER: -25°C to 85°C), breaking capacity (Littelfuse: 10 kA; SCHURTER: 100 A), and approval certifications (Littelfuse: CSA, QPL, UL; SCHURTER: cURus).

Q: Are both parts RoHS compliant?

A: Yes, both the Littelfuse 0262001.V and SCHURTER 0034.4221 are ROHS3 Compliant.

Q: What should I verify before substituting these parts?

A: Confirm that your application operates within the SCHURTER part's temperature range (-25°C to 85°C), verify PCB layout accommodates the dimensional differences (Littelfuse: 5.97mm Dia x 7.37mm H; SCHURTER: 6.40mm Dia x 8.80mm H), and confirm that cURus certification meets your regulatory requirements.
