Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0216.080MXP is determined by strict equivalence in the following parameters:

• Current Rating: 80 mA (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Package / Case: 5mm x 20mm (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Fast Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 1.5 kA (exact match required)

Two substitute parts meet these criteria:

1. Littelfuse 0216.080HXP - Direct manufacturer variant within the same 216 series
2. Eaton BK1/S501-80-R - Cross-manufacturer equivalent from Eaton Electronics Division, S501 series

Both substitutes maintain identical electrical ratings, mechanical dimensions, and functional performance characteristics required for direct replacement in holder-based applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and satisfy core electrical and mechanical compatibility requirements for 5mm x 20mm holder-based applications at 80 mA, 250 V AC/DC ratings.

Littelfuse 0216.080HXP is a direct manufacturer variant within the Littelfuse 216 series, offering identical specifications and certifications (CCC, CE, CSA, SEMKO, UR, VDE) to the primary part. This variant is suitable for applications requiring continuity within the Littelfuse product line.

Eaton BK1/S501-80-R is a cross-manufacturer substitute from Eaton Electronics Division. It maintains equivalent electrical performance and mechanical compatibility. Regulatory certifications include CSA and cULus. This part is suitable for applications where cross-manufacturer sourcing is acceptable and provides alternative supply chain options.

Selection between these substitutes should be based on supply availability, procurement requirements, and existing design qualification within the target application.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse 0216.080HXP be used as a direct replacement for the 0216.080MXP?

A: Yes. Both parts are manufactured by Littelfuse, share identical electrical ratings (80 mA, 250 V AC/DC), ceramic cartridge construction, 5mm x 20mm package dimensions, fast-blow response, and 1.5 kA breaking capacity. They are mechanically and electrically interchangeable in holder-based applications.

Q: What are the key differences between the Littelfuse and Eaton substitutes?

A: The Littelfuse 0216.080HXP and Eaton BK1/S501-80-R are electrically and mechanically equivalent. Differences include manufacturer origin, series designation (216 vs. S501), regulatory certifications (Littelfuse includes VDE and SEMKO; Eaton includes cULus), and DC cold resistance specifications (7.885 Ohms vs. 27.9 Ohms). Both are suitable for direct replacement in 5mm x 20mm holder applications.

Q: Are all three parts compatible with the same fuse holder?

A: Yes. All three parts conform to the 5mm x 20mm package standard and require a compatible holder. Mechanical dimensions are identical across all variants.

Q: What certifications apply to each substitute part?

A: Littelfuse 0216.080MXP and 0216.080HXP carry CCC, CE, CSA, SEMKO, UR, and VDE certifications. Eaton BK1/S501-80-R carries CSA and cULus certifications. Selection should account for regional regulatory requirements.

Q: Can these parts be used in AC and DC applications?

A: Yes. All three parts are rated for 250 V AC/DC operation and are suitable for both AC and DC circuit protection applications within the specified voltage and current parameters.
