Littelfuse 0218.080TXP Glass Cartridge Fuse Equivalent & Substitute Parts

Part Overview

The Littelfuse 0218.080TXP is an 80 mA, 250 V AC/DC slow-blow glass cartridge fuse in 5mm x 20mm form factor. This component is active in production and widely used in electronic equipment requiring overcurrent protection. Substitute parts are identified when equivalent electrical and mechanical parameters are required for design flexibility, supply chain alternatives, or component availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 0218.080TXP is determined by strict equivalence in the following parameters:

• Current Rating: 80 mA (exact match required)
• Voltage Rating: 250 V AC (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: 5mm x 20mm (exact match required)
• Breaking Capacity: 35A (exact match required)
• Operating Temperature: -55°C ~ 125°C (exact match required)

All identified substitute parts meet these criteria. Variations in secondary parameters such as melting I²t, DC cold resistance, and specific approval agencies do not preclude substitution when primary electrical and mechanical parameters are identical.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products with current manufacturing status. Selection among equivalent parts may be based on:

• Inventory availability and lead time requirements
• Approval agency certifications required for specific applications (CCC, CE, CSA, UL, VDE, K-MARK, cURus)
• Manufacturer preference or existing supply chain relationships
• DC cold resistance specifications if circuit design requires specific impedance characteristics

The Littelfuse 0218.080MXP offers the highest inventory level (2200 pcs) among all equivalents. SCHURTER parts (0034.3106 and 0034.5606.11) provide alternative sourcing from a different manufacturer while maintaining identical electrical and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can the 0218.080TXP be directly replaced with 0218.080HXP or 0218.080MXP?

A: Yes. Both Littelfuse alternatives are parametric equivalents with identical current rating, voltage rating, response time, package dimensions, breaking capacity, and operating temperature range. They are direct mechanical and electrical substitutes.

Q: Are SCHURTER fuses (0034.3106, 0034.5606.11) compatible with the same fuse holder as the Littelfuse 0218.080TXP?

A: Yes. Both manufacturers produce 5mm x 20mm cartridge glass fuses with identical package dimensions and mounting requirements. They are mechanically and electrically interchangeable in the same holder.

Q: What is the difference between the Littelfuse variants (TXP, HXP, MXP)?

A: The three Littelfuse part numbers are parametric equivalents. Differences exist in melting I²t and DC cold resistance values, but these do not affect substitution eligibility when primary electrical parameters (current, voltage, response time) and mechanical parameters (package, breaking capacity) are identical.

Q: Which substitute part should be selected for new designs?

A: Selection depends on application-specific requirements. Verify that the required approval agencies (CCC, CE, CSA, UL, VDE, K-MARK, cURus) are present on the chosen part number. All listed substitutes meet ROHS3 compliance and REACH unaffected status.

Q: Can these fuses be used interchangeably in existing equipment?

A: Yes, provided the equipment design specifies an 80 mA, 250 V AC/DC slow-blow cartridge fuse in 5mm x 20mm form factor. No circuit modifications are required.
