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

Part Overview

The Littelfuse 0217.080HXP 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 compatible fuse holder for installation. Equivalent and substitute parts are identified based on matching electrical ratings, mechanical dimensions, response characteristics, and regulatory compliance to ensure direct functional interchangeability in protected circuits.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0217.080HXP is determined by strict equivalence across 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: Fast Blow (exact match required)
• Package Dimensions: 5mm x 20mm (exact match required)
• Breaking Capacity: 35A (exact match required)

All substitute parts listed below meet these criteria and are therefore electrically and mechanically interchangeable with the main part in applications requiring 80mA, 250VAC fast-blow protection in standard 5x20mm fuse holders.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are Active products with ROHS3 compliance status. The 0217.080MXP (Littelfuse) maintains identical specifications to the main part and carries the same regulatory certifications (CCC, CE, CSA, K-MARK, SEMKO, UL, VDE). The 0034.1531 (SCHURTER) is certified by CCC, cURus, and VDE. The Eaton parts (BK/S500-80-R and GDB-80MA) provide functional equivalence but with limited or unspecified approval agency documentation.

Selection should prioritize parts with documented regulatory compliance matching the application's certification requirements. All parts are suitable for direct replacement in 5x20mm fuse holder installations requiring 80mA, 250VAC fast-blow protection.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the 0217.080HXP?

A: Yes. All listed parts meet the core electrical and mechanical specifications: 80mA current rating, 250VAC voltage rating, fast-blow response, 35A breaking capacity, and 5x20mm form factor. They are mechanically and electrically interchangeable in standard 5x20mm fuse holders.

Q: What is the difference between the 0217.080HXP and 0217.080MXP?

A: Both are Littelfuse 80mA, 250VAC fast-blow glass cartridge fuses in 5x20mm form factor with identical electrical and mechanical specifications. They differ only in internal construction characteristics (HXP vs. MXP designation) but maintain equivalent performance and certifications.

Q: Are there differences in melting I²t values among these parts?

A: Minor variations exist in melting I²t values (ranging from 0.00083 to 0.0012), reflecting differences in internal fuse element design. These variations remain within acceptable tolerance for 80mA fast-blow cartridge fuses and do not affect substitution eligibility for standard circuit protection applications.

Q: Do all substitute parts have the same regulatory certifications?

A: No. The Littelfuse parts (0217.080HXP and 0217.080MXP) carry certifications from CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE. The SCHURTER part (0034.1531) is certified by CCC, cURus, and VDE. The Eaton parts have limited or unspecified approval agency documentation. Verify certification requirements for your specific application before selection.

Q: What is the DC cold resistance specification, and why does it vary?

A: DC cold resistance values (7.89 Ohms for Littelfuse, 5 Ohms for Eaton) represent the resistance of the fuse element at room temperature. Variations reflect different internal element designs but do not affect substitution compatibility for standard AC/DC circuit protection applications.

Q: Can these fuses be used in both AC and DC circuits?

A: Yes. All listed parts are rated for 250V AC and DC operation. The 80mA current rating and fast-blow response apply to both AC and DC applications within the specified voltage range.

Q: What is the significance of the 5x20mm package dimension?

A: The 5x20mm dimension specifies the physical form factor required for compatibility with standard 5x20mm fuse holders. All substitute parts maintain this exact dimension and are therefore mechanically compatible with any holder designed for this form factor.
