Littelfuse 0218.080VXP Glass Cartridge Fuse 80mA 250VAC 5x20mm Equivalent & Substitute Parts

Part Overview

The Littelfuse 0218.080VXP is an 80mA 250VAC slow-blow glass cartridge fuse in 5x20mm form factor, requiring a dedicated holder for installation. This component is Active status and widely used in circuit protection applications across industrial and consumer electronics. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained, ensuring direct functional replacement without circuit redesign.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: current rating (80 mA), voltage rating (250 V AC), fuse type (cartridge glass), response time (slow blow), physical package (5x20mm), breaking capacity (35A), and operating temperature range (-55°C ~ 125°C). All identified substitutes maintain these core electrical and mechanical specifications. Variations in secondary parameters such as melting I²t, DC cold resistance, and specific approval agencies do not disqualify substitution when primary parameters remain identical.

Engineering Selection Recommendations

All identified substitute parts maintain Active product status and ROHS3 compliance. Selection between Littelfuse 0218.080VXP and its direct equivalents (0218.080HXP, 0218.080MXP) is based on inventory availability and approval agency requirements. The 0218.080MXP offers the highest inventory level (2200 Pcs) among Littelfuse variants. SCHURTER alternatives (0034.3106, 0034.5606.11) provide equivalent electrical performance with reduced approval agency coverage; 0034.3106 includes CCC certification matching the original part, while 0034.5606.11 is limited to cURus and VDE certifications. Selection should align with specific regulatory requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can 0218.080HXP or 0218.080MXP be used as direct replacements for 0218.080VXP? A: Yes. Both parts maintain identical current rating (80 mA), voltage rating (250 V AC), response time (slow blow), physical package (5x20mm), and breaking capacity (35A). Differences in melting I²t and DC cold resistance do not affect substitution eligibility under the specified parameters.

Q: What is the difference between Littelfuse and SCHURTER fuse options? A: Both manufacturers provide 80mA 250VAC slow-blow glass cartridge fuses in 5x20mm packages with 35A breaking capacity. Littelfuse variants (0218.080VXP, 0218.080HXP, 0218.080MXP) carry broader approval agency certifications including KC and SEMKO. SCHURTER parts (0034.3106, 0034.5606.11) provide equivalent electrical performance with more limited certifications.

Q: Are these fuses interchangeable in the same holder? A: Yes. All substitute parts share the identical 5x20mm physical package and require the same holder type. No mechanical modification is necessary for installation.

Q: Which substitute offers the best inventory availability? A: Littelfuse 0218.080MXP provides the highest stock level at 2200 Pcs, followed by SCHURTER 0034.3106 at 1876 Pcs.

Q: Do all substitutes meet the same regulatory certifications? A: No. The original 0218.080VXP includes CCC, CE, CSA, KC, SEMKO, UL, and VDE certifications. Littelfuse alternatives maintain most certifications with K-MARK replacing KC. SCHURTER 0034.3106 includes CCC but lacks UL and SEMKO. SCHURTER 0034.5606.11 has the most limited certification scope (cURus, VDE only). Verify certification requirements for your specific application before selection.
