Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters:

Current Rating: 2 A (exact match required)
Voltage Rating (AC): 250 V (exact match required)
Package / Case: 5x20mm (exact match required)
Fuse Type: Cartridge, Ceramic (exact match required)
Response Time: Slow Blow (exact match required)
Mounting Type: Requires Holder (exact match required)

All substitute parts listed maintain these core electrical and mechanical specifications. Variations in secondary parameters such as Melting I²t, DC Cold Resistance, and approval agency certifications do not disqualify substitution when primary parameters align. Parts from different manufacturers (Littelfuse, SCHURTER, Bel Fuse, OptiFuse) are included when they satisfy all primary parameter requirements.

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance. Selection among equivalents should prioritize inventory availability and certification scope relevant to the target application:

Littelfuse 0215002 series (HXP, MXP, TXP, VXP variants) offer the broadest approval agency coverage including CCC, CE, CSA, KC, PSE, SEMKO, UL, and VDE certifications, making them suitable for applications requiring multi-regional compliance.

SCHURTER 0001.2507 and 0001.2707.11 provide additional DC voltage rating (300V DC) beyond the AC specification, applicable in mixed AC/DC circuit environments. Approval agencies include CCC, cURus, KC, PSE/JET, and VDE.

Bel Fuse 0659C2000-12 delivers the highest Melting I²t value (14) among equivalents, suitable for applications with higher inrush current tolerance. Certifications include CCC, cURus, PSE, and VDE.

OptiFuse TCD-2A maintains 1.5kA breaking capacity with cURus and IEC 60127 approvals, appropriate for IEC-compliant circuit designs. OptiFuse TCC-2A features lower breaking capacity (100A) and cULus/UL 248 certification, suitable for UL-regulated applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 0285002.HXP with any of the listed parts without modifying my circuit?

A: Yes. All listed substitute parts maintain identical current rating (2A), AC voltage rating (250V), package dimensions (5x20mm), and mounting requirements (requires holder). Direct substitution is electrically and mechanically compatible.

Q: What is the significance of Melting I²t variation among substitutes?

A: Melting I²t indicates the thermal energy required to melt the fuse element. Variations (9.2 to 14) reflect different fuse element designs but do not affect substitution eligibility when current and voltage ratings match. Selection should consider application inrush current characteristics; higher I²t values tolerate greater transient currents.

Q: Do all substitutes have the same approval certifications?

A: No. Littelfuse 0215002 variants offer the most comprehensive certification coverage (CCC, CE, CSA, KC, PSE, SEMKO, UL, VDE). SCHURTER and Bel Fuse parts carry regional certifications (CCC, cURus, PSE, VDE). OptiFuse parts feature UL or IEC certifications. Select based on your application's regulatory requirements.

Q: Why does the SCHURTER 0001.2507 list a 300V DC rating when the main part specifies only 250V AC?

A: SCHURTER parts are rated for both 250V AC and 300V DC operation, providing broader application flexibility. This does not disqualify substitution; it represents an extended capability that maintains compatibility with 250V AC circuits.

Q: Is DC Cold Resistance a critical substitution parameter?

A: No. DC Cold Resistance (0.0546 to 0.0585 Ω) represents the fuse element's resistance at room temperature and does not affect substitution eligibility. Variations reflect manufacturing tolerances and element design differences but do not impact circuit protection function when current and voltage ratings are identical.

Q: Which substitute offers the best inventory availability?

A: Littelfuse 0215002.MXP provides the highest stock level at 54,700 pieces, followed by Bel Fuse 0659C2000-12 at 17,013 pieces. Availability should be verified with your supplier for current stock status.
