Key Parameters

Substitute Part Grouping Explanation

Substitution of the PWR4412-2SCR0200F is determined by strict equivalence across the following critical parameters:

• Resistance value: 20 mOhms
• Tolerance: ±1%
• Power rating: 3W
• Composition: Metal Element
• Package configuration: Radial with 2 terminations
• Temperature coefficient: ±20ppm/°C
• RoHS3 compliance

The MSR3-0R02F1 from Riedon meets all these core electrical and mechanical requirements, establishing it as a direct functional equivalent despite differences in physical dimensions and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The MSR3-0R02F1 is the qualified substitute for the obsolete PWR4412-2SCR0200F. Both components maintain identical electrical specifications and regulatory compliance. The Riedon part offers extended operating temperature range (-65°C to 275°C versus -55°C to 270°C) and enhanced feature set including flame proof and non-inductive characteristics. Physical dimensions differ slightly, requiring verification of PCB layout compatibility. The MSR3-0R02F1 carries active product status with established supply availability, eliminating obsolescence risk associated with the original Bourns component.

Frequently Asked Questions (FAQ)

Q: Can MSR3-0R02F1 be used as a direct replacement for PWR4412-2SCR0200F?

A: Yes. Both components share identical resistance (20 mOhms), tolerance (±1%), power rating (3W), temperature coefficient (±20ppm/°C), and radial package configuration with 2 terminations. Both are ROHS3 compliant and REACH unaffected.

Q: What are the physical dimension differences?

A: PWR4412-2SCR0200F measures 0.600" L x 0.189" W (15.24mm x 4.80mm). MSR3-0R02F1 measures 0.598" L x 0.067" W (15.20mm x 1.70mm). Both have maximum seated height of 1.000" (25.40mm). Verify PCB footprint compatibility before implementation.

Q: Does the MSR3-0R02F1 offer any performance advantages?

A: The MSR3-0R02F1 extends the operating temperature range to -65°C to 275°C and includes additional features: flame proof, non-inductive, and safety certification. These enhancements do not affect core current sense functionality but may provide benefits in demanding thermal environments.

Q: Are there any compliance or regulatory differences?

A: Both components are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. No regulatory barriers exist for substitution.

Q: What is the moisture sensitivity level of the substitute?

A: MSR3-0R02F1 carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
