Equivalent & Substitute Parts for Littelfuse 0215002.MXF34P

Part Overview

The Littelfuse 0215002.MXF34P is a 2A 250VAC ceramic cartridge fuse with radial bend cylinder packaging, designed for through-hole mounting applications. This fuse provides slow-blow response characteristics and is rated for breaking capacity of 1.5kA at rated voltage. The part maintains active product status with full compliance to international safety standards including UL, VDE, CE, CSA, and CCC certifications. Alternative equivalent parts may be required due to packaging availability, mounting configuration differences, or specific application voltage requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the Littelfuse 0215002.MXF34P is determined by the following critical parameters:

• Current Rating: Must be 2 A
• AC Voltage Rating: Must be minimum 250 V
• Fuse Type: Must be Cartridge, Ceramic
• Response Time: Must be Slow Blow
• Breaking Capacity: Must be 1.5 kA at rated voltage
• Operating Temperature: Must support -55°C to 125°C range
• Physical Dimensions: Must be 5.20mm x 20.00mm
• Compliance Standards: Must maintain equivalent international certifications

The SCHURTER 0001.2507 meets all substitution criteria. While this part requires a separate holder for mounting (versus the radial bend cylinder configuration of the main part), it maintains electrical equivalence across all critical parameters and provides additional DC voltage rating capability at 300V.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 0001.2507 provides electrical equivalence to the Littelfuse 0215002.MXF34P across all critical fuse parameters. Both parts maintain active product status and comply with international safety standards. The primary design consideration is the mounting configuration: the Littelfuse part features integrated radial bend cylinder packaging for direct through-hole mounting, while the SCHURTER part requires a separate fuse holder. Selection between these parts depends on circuit board layout and available mounting infrastructure. Both parts maintain ROHS3 compliance and equivalent operating temperature specifications. The SCHURTER part provides additional DC voltage rating capability at 300V, which may offer flexibility for dual-voltage applications.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 0001.2507 be used as a direct replacement for the Littelfuse 0215002.MXF34P?

A: Electrical substitution is valid. The SCHURTER part matches all critical electrical parameters including current rating, AC voltage rating, breaking capacity, and response time. However, the mounting configuration differs: the Littelfuse part has integrated radial leads for direct through-hole mounting, while the SCHURTER part requires a separate 5x20mm fuse holder. Circuit board redesign or holder installation may be necessary.

Q: What is the significance of the different Melting I²t values?

A: The Melting I²t value (11.68 for Littelfuse versus 9.2 for SCHURTER) indicates the thermal energy required to melt the fuse element. Both values are within the slow-blow ceramic fuse category for 2A rated current. The difference reflects manufacturing variations in element design while maintaining equivalent 2A current rating and response characteristics.

Q: Are both parts suitable for AC and DC applications?

A: Both parts are rated for 250V AC operation. The SCHURTER part additionally specifies 300V DC rating, providing broader application flexibility. The Littelfuse part does not specify a DC voltage rating in the provided data.

Q: Do both parts meet the same international compliance standards?

A: Both parts maintain compliance with CCC, KC, PSE, and VDE standards. The Littelfuse part includes additional certifications (CE, CSA, SEMKO, UL), while the SCHURTER part includes cURus and PSE/JET certifications. Both are suitable for applications requiring international safety compliance.

Q: What is the impact of the different packaging on circuit design?

A: The Littelfuse radial bend cylinder design allows direct PCB mounting without additional components. The SCHURTER 5x20mm cartridge requires a compatible fuse holder, which adds component count and board space. Application requirements and available board real estate determine the appropriate selection.
