Substitute Part Grouping Explanation

Substitution for the 0218010.H is determined by strict equivalence across the following parameters:

Current Rating: 10A (exact match required)
Voltage Rating: 250V AC (exact match required)
Fuse Type: Cartridge, Glass (exact match required)
Response Time: Slow Blow (exact match required)
Package / Case: 5mm x 20mm (exact match required)
Mounting Type: Requires Holder (exact match required)

Substitute parts are grouped into two categories:

Littelfuse 218 Series (Parametric Equivalents): Parts 0218010.HXP, 0218010.MXBP, 0218010.MXF11P, 0218010.MXP, and 0218010.TXP maintain identical electrical and mechanical specifications. These parts are active products with enhanced compliance certifications (ROHS3 compliant) compared to the obsolete 0218010.H.

Littelfuse 618 Series (Parametric Equivalent): Part 0618010.MXP shares identical electrical and mechanical parameters but belongs to a different series designation.

Cross-Manufacturer Alternatives: Parts from SCHURTER Inc. (0034.5627.22) and Bel Fuse Inc. (5ET 10-R, 5ST 10-R) meet the core electrical and mechanical requirements but may have minor variations in melting I²t and breaking capacity specifications.

Engineering Selection Recommendations

For direct replacement of the obsolete 0218010.H, the Littelfuse 218 series active products (0218010.HXP, 0218010.MXBP, 0218010.MXF11P, 0218010.MXP, 0218010.TXP, 0218010.VXP) are the primary selection. These parts maintain identical electrical and mechanical specifications while offering ROHS3 compliance and expanded certification coverage (CE, CSA, K-MARK, PSE, UL, VDE).

The Littelfuse 0618010.MXP from the 618 series provides equivalent functionality with identical core parameters and active product status, though it carries different regulatory certifications (CE, CSA, UR, VDE).

Cross-manufacturer alternatives from SCHURTER Inc. (0034.5627.22) and Bel Fuse Inc. (5ET 10-R, 5ST 10-R) are suitable for applications where multi-source qualification is required. Note that the Bel Fuse 5ET 10-R has a higher breaking capacity (150A vs. 100A), and the 5ST 10-R has a significantly lower breaking capacity (10A vs. 100A), which may affect suitability depending on circuit protection requirements.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the 0218010.H?

A: Yes, all listed substitute parts meet the core electrical and mechanical requirements: 10A current rating, 250V AC voltage rating, slow-blow response, 5x20mm package, and cartridge glass fuse type. Physical compatibility with existing fuse holders is maintained across all substitutes.

Q: What is the difference between the Littelfuse 218 and 618 series parts?

A: Both series share identical electrical and mechanical specifications for this 10A 250V application. The series designation reflects internal product line organization. The 618 series (0618010.MXP) carries different regulatory certifications (UR instead of K-MARK and PSE) and has MSL rating of 1 (Unlimited) versus Not Applicable for 218 series parts.

Q: Why do the Bel Fuse parts have different breaking capacities?

A: The 5ET 10-R has a breaking capacity of 150A, and the 5ST 10-R has 10A, compared to 100A for the Littelfuse parts. Breaking capacity defines the maximum fault current the fuse can safely interrupt. Selection should be based on the specific circuit protection requirements of your application.

Q: Are all substitute parts RoHS compliant?

A: Yes, all active substitute parts listed are ROHS3 compliant. The original 0218010.H is marked as RoHS non-compliant due to its obsolete status.

Q: What certifications should I consider for my application?

A: The Littelfuse 218 series parts carry the broadest certification coverage (CE, CSA, K-MARK, PSE, UL, VDE). The 0618010.MXP carries CE, CSA, UR, and VDE. SCHURTER 0034.5627.22 carries CQC, cURus, and VDE. Bel Fuse parts carry CE and SEMKO (5ET 10-R) or CE, CSA, and cURus (5ST 10-R). Select based on your regional and application-specific certification requirements.

Q: What is the melting I²t specification and why does it vary?

A: Melting I²t is a measure of the fuse's thermal energy capacity before melting. The original 0218010.H has a melting I²t of 583, while most active Littelfuse substitutes are 568. SCHURTER 0034.5627.22 is 520, and Bel Fuse parts range from 400-439. These variations reflect different fuse element designs but do not affect compatibility for standard 10A slow-blow applications.
