Both parts maintain identical electrical performance characteristics and radial package configuration, ensuring direct circuit compatibility without redesign requirements.

Frequently Asked Questions (FAQ)

Q: Can MSR3-0R01F1 directly replace PWR4412-2SCR0100F in existing designs?

A: Yes. Both components share identical resistance (10 mOhms), tolerance (±1%), power rating (3W), temperature coefficient (±20 ppm/°C), and radial package geometry. Direct substitution is supported without circuit modification.

Q: What is the primary reason for substitution?

A: The PWR4412-2SCR0100F is classified as obsolete. The MSR3-0R01F1 maintains active product status, ensuring long-term availability and supply reliability.

Q: Are there differences in operating temperature ranges?

A: The MSR3-0R01F1 operates from -65°C to 275°C, compared to -55°C to 270°C for the PWR4412-2SCR0100F. The substitute part supports a wider temperature envelope, providing enhanced environmental flexibility.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited), meeting equivalent regulatory and environmental requirements.

Q: Are there feature differences between the parts?

A: The MSR3-0R01F1 includes additional features (flame proof, non-inductive, safety) beyond the moisture resistance and pulse withstanding capabilities of the PWR4412-2SCR0100F. These enhancements do not affect substitution compatibility.

Q: What is the physical dimension difference?

A: The MSR3-0R01F1 measures 0.598" L x 0.067" W (15.20mm x 1.70mm), while the PWR4412-2SCR0100F measures 0.600" L x 0.189" W (15.24mm x 4.80mm). Both maintain identical maximum seated height (1.000" / 25.40mm) and radial package configuration, supporting standard PCB footprint compatibility.
