Littelfuse 0216004.H Ceramic Fuse 4A 250VAC 5x20mm – Equivalent & Substitute Parts

Part Overview

The Littelfuse 0216004.H is a 4A 250VAC ceramic cartridge fuse in the 5x20mm form factor, designed for fast-blow protection in AC and DC circuits. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new designs. Active alternatives from Littelfuse and other manufacturers provide identical electrical performance with improved availability and compliance status.

Substitute Part Grouping Explanation

Substitution for the 0216004.H is determined by strict equivalence across the following parameters: current rating (4A), voltage rating (250VAC), fuse type (ceramic cartridge), package dimensions (5x20mm), response time (fast blow), and breaking capacity (1.5kA). All substitute parts listed maintain these core electrical and mechanical specifications.

Littelfuse parametric equivalents (0216004.HXP, 0216004.MXBP, 0216004.MXP, 0216004.TXP, 0216004.VXP) are direct replacements from the same manufacturer with active product status and improved RoHS3 compliance. Cross-manufacturer alternatives from Bel Fuse Inc. and Eaton Electronics Division meet identical electrical parameters and are qualified as manufacturer-recommended substitutes.

Engineering Selection Recommendations

All listed substitute parts are electrically and mechanically equivalent to the 0216004.H. Selection should prioritize active product status and compliance requirements.

Littelfuse parametric equivalents (0216004.HXP, 0216004.MXBP, 0216004.MXP, 0216004.TXP, 0216004.VXP) are the primary recommendation for direct replacement. These parts maintain Littelfuse series continuity, carry ROHS3 compliance, and are actively manufactured with higher inventory availability than the obsolete 0216004.H.

Cross-manufacturer alternatives from Bel Fuse Inc. (5HF 4-R) and Eaton Electronics Division (BK/GDA-4A, BK/S501-4-R, BK1/S501-4-R, GDA-4A) are qualified substitutes with active status and ROHS3 compliance. These options provide supply chain flexibility and are supported by equivalent approval agencies including CCC, CE, CSA, UL, and VDE certifications.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the 0216004.H?

A: Yes. All listed parts meet the core electrical parameters (4A, 250VAC, 1.5kA breaking capacity) and mechanical specifications (5x20mm ceramic cartridge, fast-blow response). They are direct functional equivalents and require the same holder type.

Q: Why is the 0216004.H classified as obsolete?

A: The 0216004.H is no longer in active production. Littelfuse has transitioned to active variants (0216004.HXP, 0216004.MXBP, 0216004.MXP, 0216004.TXP, 0216004.VXP) that provide improved compliance and manufacturing continuity.

Q: What is the difference between Littelfuse parametric equivalents and cross-manufacturer alternatives?

A: Littelfuse parametric equivalents maintain the same manufacturer and series lineage, ensuring consistency with existing supply chains and documentation. Cross-manufacturer alternatives from Bel Fuse Inc. and Eaton Electronics Division provide equivalent electrical and mechanical performance with different approval agency certifications and sourcing options.

Q: Are there any differences in DC cold resistance between the main part and substitutes?

A: The 0216004.H has a DC cold resistance of 0.025 Ohms. Littelfuse parametric equivalents specify 0.0247 Ohms, and cross-manufacturer alternatives range from 0.023 to 0.027 Ohms. These variations are within acceptable tolerance for ceramic cartridge fuses and do not affect circuit protection performance.

Q: Do all substitute parts require the same holder as the 0216004.H?

A: Yes. All substitute parts are 5x20mm ceramic cartridge fuses requiring a standard 5x20mm fuse holder. No holder modifications are necessary.

Q: Which substitute part offers the best availability?

A: Littelfuse parametric equivalents (0216004.MXP with 1670 units, 0216004.HXP with 1545 units) and Bel Fuse Inc. 5HF 4-R (2307 units) offer the highest current inventory levels.
