Key Parameters

Substitute Part Grouping Explanation

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

Primary Equivalence Criteria:

• Current Rating: 4 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Package / Case: 5mm x 20mm (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Fast Blow (exact match required)
• Mounting Type: Requires Holder (exact match required)

Secondary Compatibility Factors:

• Operating Temperature Range: -55°C ~ 125°C (minimum requirement)
• Breaking Capacity @ Rated Voltage: 1.5kA or higher (minimum requirement)
• RoHS3 Compliance (required for environmental standards)

All substitute parts listed meet these criteria without exception.

Parameter Comparison

Engineering Selection Recommendations

Littelfuse Internal Variants (0216004.HXP, 0216004.MXP, 0216004.VXP): These parts are parametric equivalents of the primary part number 0216004.TXP, differing only in packaging designation. All carry identical electrical specifications, approval agencies (CCC, CE, CSA, KC, PSE, SEMKO, UL, VDE), and performance characteristics. Selection among these variants is based on inventory availability and supply chain logistics.

SCHURTER 0001.1010: This direct manufacturer substitute meets all critical electrical parameters and maintains the same operating temperature range and breaking capacity. Approval agencies include CCC, cURus, KC, PSE/JET, and VDE. The melting I²t value of 12.6 is lower than the Littelfuse reference, indicating slightly faster thermal response. This part is suitable for applications where cross-manufacturer sourcing is acceptable.

OptiFuse FCC-4A: This parametric equivalent maintains all required electrical ratings and temperature specifications. Approval coverage includes cULus and UL 248. The breaking capacity specification differs (200A versus 1.5kA), and DC cold resistance is marginally higher at 0.0275 Ohms. This part is suitable for applications requiring UL-specific certifications.

OptiFuse FCD-4A: This parametric equivalent includes explicit 250V DC voltage rating in addition to 250V AC, providing broader voltage compatibility. Approval is based on IEC 60127 standard. The melting I²t value of 12.22 indicates faster thermal response compared to the primary part. This part is suitable for applications requiring dual AC/DC voltage specifications.

Frequently Asked Questions (FAQ)

Q: Can I use 0216004.HXP, 0216004.MXP, or 0216004.VXP interchangeably with 0216004.TXP?

A: Yes. These Littelfuse variants are parametric equivalents with identical electrical specifications, current rating, voltage rating, package dimensions, response time, and approval certifications. The suffix designations reflect internal packaging or manufacturing process variations only.

Q: What is the difference between the Littelfuse and SCHURTER substitutes?

A: Both maintain 4A at 250VAC in 5mm x 20mm ceramic cartridge format with fast-blow response. The SCHURTER 0001.1010 has a lower melting I²t value (12.6 versus 14.995), resulting in slightly faster thermal response. Approval agencies differ slightly, with SCHURTER including cURus and PSE/JET certifications.

Q: Can I use OptiFuse FCC-4A or FCD-4A as direct replacements?

A: Yes, both OptiFuse parts meet all critical electrical and mechanical parameters. FCC-4A carries UL 248 certification, while FCD-4A includes explicit 250V DC rating. Selection depends on specific certification requirements for your application.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant status, meeting environmental and hazardous substance restrictions.

Q: What happens if I use a fuse with different melting I²t characteristics?

A: Melting I²t determines thermal response speed. Lower values (SCHURTER 12.6, OptiFuse 12.22-13.683) indicate faster thermal response compared to the primary part (14.995). Selection should align with circuit protection requirements and equipment design specifications.

Q: Do all substitutes fit the same 5mm x 20mm holder?

A: Yes. All listed parts are specified for 5mm x 20mm package dimensions and require standard ceramic cartridge fuse holders designed for this size.

Q: Which substitute has the highest inventory availability?

A: OptiFuse FCD-4A has the highest inventory at 2208 pieces, followed by Littelfuse 0216004.MXP at 1670 pieces.
