Key Parameters

Substitute Part Grouping Explanation

Substitution for the 0217.080TXP is determined by strict equivalence across the following electrical and mechanical 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: Fast Blow (exact match required)
• Physical Package: 5mm x 20mm (exact match required)
• Breaking Capacity: 35 A (exact match required)
• Operating Temperature: -55°C to 125°C (exact match required)

All identified substitute parts meet these criteria without deviation. Substitutes are grouped by manufacturer and series designation while maintaining identical electrical performance and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and comply with international safety standards. Selection between 0217.080TXP, 0217.080MXP, and 0034.1531 is based on availability and certification requirements:

The Littelfuse 0217.080TXP and 0217.080MXP are direct equivalents within the same manufacturer series (217), differing only in packaging designation. Both carry identical electrical specifications and certifications including CCC, CE, CSA, SEMKO, UL, and VDE.

The SCHURTER 0034.1531 (FSF 5x20 series) provides an alternative from a different manufacturer with equivalent electrical performance. This part carries CCC, cURus, and VDE certifications. The melting I²t value of 0.00102 is slightly higher than the Littelfuse parts (0.00083), remaining within acceptable tolerance for this fuse classification.

Selection should prioritize parts with the highest current inventory availability and certifications matching the specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can 0217.080MXP directly replace 0217.080TXP?

A: Yes. Both parts are Littelfuse Series 217 components with identical electrical ratings (80 mA, 250 V AC), response time (Fast Blow), physical dimensions (5mm x 20mm), and breaking capacity (35 A). The designation difference reflects packaging variation only.

Q: Is the SCHURTER 0034.1531 a direct substitute?

A: Yes. The 0034.1531 meets all electrical and mechanical requirements: 80 mA current rating, 250 V AC voltage rating, fast-blow response, 5mm x 20mm package, and 35 A breaking capacity. Operating temperature range and physical dimensions are identical. The melting I²t specification (0.00102) is slightly higher but remains within acceptable parameters for this fuse type.

Q: What certifications apply to all substitute parts?

A: All three parts hold CCC, VDE, and ROHS3 compliance. The Littelfuse parts (0217.080TXP and 0217.080MXP) additionally carry CE, CSA, SEMKO, and UL certifications. The SCHURTER part carries cURus certification. Verify specific certification requirements for your application before selection.

Q: Are there mechanical compatibility concerns when substituting?

A: No. All parts share identical physical dimensions (0.205" diameter x 0.787" length / 5.20mm x 20.00mm) and require the same holder type. Direct mechanical substitution is supported without modification to mounting hardware or circuit design.

Q: What is the significance of the melting I²t difference?

A: The melting I²t value indicates thermal energy required to melt the fuse element. The SCHURTER part (0.00102) versus Littelfuse parts (0.00083) represents a minor variation within the 80 mA fast-blow classification. Both values are appropriate for this current rating and do not affect functional compatibility in standard applications.
