Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PWR4412-2SDR1000F is determined by the following critical parameters:

• Resistance value: 100 mOhms ±1%
• Power rating: 5W minimum
• Package configuration: Radial through-hole
• Composition: Metal Element
• Temperature coefficient: ±20 ppm/°C
• RoHS3 compliance
• Operating temperature range compatibility

The MSR5-0R1F1 manufactured by Riedon meets all substitution criteria. Both components share identical resistance, tolerance, power rating, composition, temperature coefficient, and RoHS compliance status. The substitute part maintains radial package configuration with compatible physical dimensions and termination count.

Parameter Comparison

Engineering Selection Recommendations

The MSR5-0R1F1 is the direct substitute for the obsolete PWR4412-2SDR1000F. Selection is based on the following factors:

• Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements
• The substitute part is classified as active product status, ensuring ongoing availability and supply chain continuity
• Operating temperature range of the MSR5-0R1F1 (-65°C to 275°C) exceeds the original specification (-55°C to 270°C), providing extended operational capability
• Electrical parameters are identical across all critical specifications: resistance, tolerance, power rating, and temperature coefficient
• Physical package configuration and termination count are compatible with existing PCB layouts designed for the PWR4412-2SDR1000F

Frequently Asked Questions (FAQ)

Q: Can the MSR5-0R1F1 be used as a direct replacement for the PWR4412-2SDR1000F?

A: Yes. Both components share identical electrical specifications (100 mOhms ±1%, 5W, ±20 ppm/°C) and radial package configuration. The substitute part meets or exceeds all critical parameters required for current sense applications.

Q: What are the physical dimension differences between these parts?

A: The PWR4412-2SDR1000F measures 0.800" L x 0.189" W (20.32mm x 4.80mm), while the MSR5-0R1F1 measures 0.799" L x 0.067" W (20.30mm x 1.70mm). Both have a maximum seated height of 1.000" (25.40mm). The width difference does not affect PCB compatibility for radial through-hole mounting.

Q: Are there compliance or certification differences?

A: Both components are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. No compliance barriers exist for substitution.

Q: What is the temperature range difference?

A: The MSR5-0R1F1 operates from -65°C to 275°C, compared to the PWR4412-2SDR1000F range of -55°C to 270°C. The substitute part provides extended low-temperature capability and slightly higher maximum temperature rating.

Q: Is the MSR5-0R1F1 currently available?

A: Yes. The MSR5-0R1F1 is classified as active product status with 1863 pieces in stock, ensuring supply availability. The original PWR4412-2SDR1000F is obsolete.
