Parameter Comparison

Engineering Selection Recommendations

The Littelfuse 0874.800MXEP (Series 874) is the designated substitute for the obsolete SCHURTER 7010.1820.12. Selection of this substitute is supported by the following factors:

Compliance and Certification:

• Both parts maintain ROHS3 compliance, ensuring regulatory alignment with current environmental standards
• The Littelfuse substitute carries cULus approval, providing recognized safety certification for AC DC fuse applications
• REACH compliance status (REACH Unaffected) confirms no restricted substance concerns

Product Availability:

• The substitute part maintains Active product status, ensuring long-term availability and continued manufacturing support
• Current inventory levels (793 Pcs) support immediate procurement requirements

Electrical and Mechanical Compatibility:

• Ceramic cartridge construction with fast-blow response time matches the functional requirements of the original part
• Through-hole axial mounting configuration and physical dimensions (3.60mm x 10.00mm) provide direct mechanical compatibility
• Operating temperature range (-55°C ~ 125°C) and DC cold resistance (0.16 Ohms) support equivalent electrical performance
• Breaking capacity of 50A at rated voltage and melting I²t of 0.39 confirm protective characteristics suitable for AC DC applications

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse 0874.800MXEP be used as a direct replacement for the SCHURTER 7010.1820.12?

A: Yes. The Littelfuse 0874.800MXEP is the designated substitute part. Both components are ceramic cartridge fuses with 800 mA current rating and 250 V AC voltage rating, meeting the electrical and mechanical requirements for direct substitution in through-hole axial mounting applications.

Q: What is the physical compatibility between these two fuse cartridges?

A: Both fuses share identical physical dimensions of 0.142" diameter by 0.394" length (3.60mm x 10.00mm). This dimensional equivalence ensures mechanical compatibility in existing fuse holders and mounting configurations designed for the original SCHURTER part.

Q: Are there any regulatory compliance differences between the original and substitute parts?

A: Both parts maintain ROHS3 compliance. The Littelfuse substitute additionally carries cULus approval certification, which provides recognized safety validation for AC DC fuse applications. No compliance barriers exist for substitution.

Q: Why is the SCHURTER 7010.1820.12 classified as obsolete?

A: The SCHURTER 7010.1820.12 has reached end-of-life status and is no longer manufactured or supported through standard distribution channels. The Littelfuse 0874.800MXEP provides equivalent functionality with active product status and ongoing manufacturing support.

Q: What is the difference between Fast Blow and other fuse response times?

A: Fast Blow fuses are designed to interrupt circuits rapidly when current exceeds the rated value. This response characteristic is suitable for protecting sensitive electronic components and circuits requiring immediate fault isolation. The Littelfuse substitute maintains this fast-blow characteristic.

Q: Are there any temperature operating range considerations for this substitution?

A: The Littelfuse 0874.800MXEP operates across a temperature range of -55°C to 125°C, providing thermal performance suitable for industrial and commercial applications. Verify that your specific application requirements fall within this operating range.

Q: What does the melting I²t value of 0.39 indicate?

A: The melting I²t value represents the thermal energy required to melt the fuse element. This value characterizes the fuse's protective response and energy dissipation characteristics. The specified value of 0.39 confirms the fuse's ability to provide reliable overcurrent protection in AC DC applications.
