Littelfuse 0262002.V Equivalent & Substitute Parts

Part Overview

The Littelfuse 0262002.V is a 2 A, 125 V AC/DC board mount radial fuse designed for through-hole applications. This fast-blow fuse is part of the Micro™ 262 series and is currently in active production status. Finding equivalent substitute parts may be necessary due to inventory constraints, lead time requirements, or specific application compatibility needs while maintaining identical electrical and mechanical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Littelfuse 0262002.V are identified based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

• Current Rating: 2 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)
• Package Configuration: Radial, Can format (compatible geometry)
• RoHS Compliance: ROHS3 Compliant (regulatory alignment)

The SCHURTER 0034.4224 meets all critical electrical parameters and maintains functional equivalence for board mount through-hole applications with identical current and voltage ratings.

Parameter Comparison

Engineering Selection Recommendations

Both the Littelfuse 0262002.V and SCHURTER 0034.4224 are active production components with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Selection between these parts should be based on:

• Electrical equivalence: Both parts satisfy identical current (2 A) and voltage (125 V AC/DC) requirements with fast-blow response characteristics
• Approval certifications: Littelfuse carries CSA, QPL, and UL approvals; SCHURTER carries cURus approvals
• Physical dimensions: The SCHURTER part is slightly larger (0.252" Dia x 0.346" H versus 0.235" Dia x 0.290" H), requiring verification of PCB layout clearance
• Operating temperature: Littelfuse supports -55°C ~ 125°C; SCHURTER supports -25°C ~ 85°C; application temperature requirements must be confirmed
• Breaking capacity: Littelfuse specifies 10 kA; SCHURTER specifies 100 A at rated voltage; application fault current levels must be evaluated

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 0034.4224 directly replace the Littelfuse 0262002.V?

A: Both parts share identical electrical specifications (2 A, 125 V AC/DC, fast-blow response). Physical dimensions differ slightly; PCB layout and clearance must be verified before substitution.

Q: What are the key differences between these two fuses?

A: The primary differences are manufacturer-specific certifications (UL/CSA versus cURus), physical package dimensions, operating temperature ranges (-55°C to 125°C versus -25°C to 85°C), and breaking capacity ratings (10 kA versus 100 A).

Q: Are both parts RoHS compliant?

A: Yes, both the Littelfuse 0262002.V and SCHURTER 0034.4224 are ROHS3 compliant and REACH unaffected.

Q: Which part should I select for high-temperature applications?

A: The Littelfuse 0262002.V supports operating temperatures up to 125°C, while the SCHURTER 0034.4224 is rated to 85°C maximum. Application temperature requirements must determine part selection.

Q: Do these fuses have different breaking capacities?

A: Yes. The Littelfuse 0262002.V has a breaking capacity of 10 kA at rated voltage, while the SCHURTER 0034.4224 has a breaking capacity of 100 A. Application fault current levels must be evaluated to ensure adequate protection.

Q: Are there any packaging or mounting differences?

A: Both are through-hole radial, can-style board mount fuses. The SCHURTER part is slightly larger in diameter and height, requiring PCB layout verification for physical fit.
