Littelfuse 0217.080MXP Glass Cartridge Fuse 80mA 250VAC 5x20mm Equivalent & Substitute Parts

Part Overview

The Littelfuse 0217.080MXP is an 80mA, 250VAC fast-blow glass cartridge fuse in 5x20mm form factor, designed for circuit protection in AC and DC applications. This Active product requires a fuse holder for installation and is RoHS3 compliant with multiple international approvals including UL, CE, VDE, CSA, and CCC. Substitute parts are identified when equivalent electrical ratings, mechanical dimensions, and functional characteristics align with the original specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0217.080MXP is determined by strict equivalence across the following parameters:

• Current Rating: 80 mA (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 5mm x 20mm (exact match required)
• Breaking Capacity @ Rated Voltage: 35A (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 affect substitutability when primary electrical and mechanical specifications are identical.

Parameter Comparison

Engineering Selection Recommendations

All four fuse models are Active products with RoHS3 compliance and REACH Unaffected status, confirming their suitability for current regulatory environments.

The 0217.080MXP (Littelfuse 217 series) carries the broadest approval agency coverage: CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE. This makes it the primary choice when maximum certification scope is required.

The 0034.1531 (SCHURTER FSF 5x20 series) provides an alternative with cURus and VDE approvals, suitable for applications where these certifications are sufficient.

The BK/S500-80-R and GDB-80MA (both Eaton Electronics Division) are functionally equivalent but do not specify approval agencies in the provided data. These parts are suitable for applications where specific certifications are not mandated.

Selection between substitute parts should be based on required approval agencies for the end application and component availability.

Frequently Asked Questions (FAQ)

Q: Can the 0034.1531 directly replace the 0217.080MXP?

A: Yes. Both parts are 80mA, 250VAC fast-blow glass cartridge fuses in 5x20mm form factor with 35A breaking capacity. They are mechanically and electrically interchangeable. Approval agency differences (0217.080MXP includes K-MARK and SEMKO; 0034.1531 includes cURus) should be evaluated against application requirements.

Q: What is the difference between the Eaton BK/S500-80-R and GDB-80MA?

A: Both are Eaton 80mA, 250VAC fast-blow glass cartridge fuses in 5x20mm form factor with identical electrical specifications. The BK/S500-80-R belongs to the S500 series while GDB-80MA belongs to the GDB series. They are functionally equivalent substitutes.

Q: Are there differences in melting I²t values between these fuses?

A: Yes. The 0217.080MXP has a melting I²t of 0.00083, while the 0034.1531 is 0.00102, and both Eaton parts are 0.0012. These variations reflect different thermal characteristics but do not affect substitutability when all other electrical and mechanical parameters are identical.

Q: Do all these fuses require the same holder?

A: Yes. All four fuses are 5x20mm cartridge glass fuses requiring a standard 5x20mm fuse holder. Mechanical compatibility is guaranteed across all substitute parts.

Q: Which substitute part has the lowest DC cold resistance?

A: Both the BK/S500-80-R and GDB-80MA have a DC cold resistance of 5 Ohms, compared to 7.89 Ohms for the 0217.080MXP. The 0034.1531 does not specify this parameter.
