Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MOS2CT52R331J is determined by the following critical parameters:

Electrical Specifications: Resistance value (330 Ohms), tolerance (±5%), and power rating (2W) must be identical. Metal oxide film composition is required to maintain thermal and electrical performance characteristics.

Mechanical Compatibility: Axial package configuration is mandatory. The component must feature two terminations for direct board-level compatibility.

Environmental & Regulatory Compliance: RoHS3 compliance and REACH unaffected status are required. Operating temperature range must support the application's thermal requirements.

Safety Features: Flame retardant or flame proof coating is required for safety compliance.

The RSF200JB-73-330R from YAGEO meets all substitution criteria through equivalent electrical specifications, axial package configuration, and regulatory compliance alignment.

Parameter Comparison

Engineering Selection Recommendations

Both the MOS2CT52R331J and RSF200JB-73-330R are active production components with full RoHS3 compliance and REACH unaffected status. Selection between these parts is based on application-specific requirements and inventory availability.

The MOS2CT52R331J operates within a -55°C to 200°C temperature range with a temperature coefficient of ±300ppm/°C. The RSF200JB-73-330R extends the upper operating temperature to 235°C, providing additional thermal margin for high-temperature applications. Both components feature flame protection coatings suitable for safety-critical applications.

Physical dimensions differ between the two parts. The MOS2CT52R331J measures 0.157" diameter by 0.472" length (4.00mm x 12.00mm), while the RSF200JB-73-330R measures 0.197" diameter by 0.610" length (5.00mm x 15.50mm). Board layout and space constraints must be evaluated when selecting between these alternatives.

Frequently Asked Questions (FAQ)

Q: Can the RSF200JB-73-330R directly replace the MOS2CT52R331J in all applications?

A: The RSF200JB-73-330R is electrically equivalent with identical resistance, tolerance, and power rating. However, physical dimensions differ. The RSF200JB-73-330R is larger (5.00mm x 15.50mm versus 4.00mm x 12.00mm), requiring verification of available board space before substitution.

Q: What is the significance of the different operating temperature ranges?

A: The MOS2CT52R331J operates from -55°C to 200°C, while the RSF200JB-73-330R operates from -55°C to 235°C. Applications requiring operation above 200°C must use the RSF200JB-73-330R. For applications within the -55°C to 200°C range, both components are suitable.

Q: Are both parts compliant with current regulatory requirements?

A: Both the MOS2CT52R331J and RSF200JB-73-330R are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component manufacturing and use.

Q: What is the difference between flame retardant and flame proof coatings?

A: The MOS2CT52R331J features flame retardant coating, while the RSF200JB-73-330R features flame proof coating. Both provide safety protection; flame proof offers enhanced fire resistance characteristics.

Q: How do packaging differences affect component selection?

A: The MOS2CT52R331J is supplied in cut tape packaging, while the RSF200JB-73-330R is supplied in bulk packaging. Packaging format affects handling, storage, and integration into assembly processes but does not impact electrical or mechanical performance.

Q: Are the temperature coefficients equivalent between these parts?

A: The MOS2CT52R331J specifies a temperature coefficient of ±300ppm/°C. The RSF200JB-73-330R does not provide a specified temperature coefficient in the available data. Applications requiring precise temperature coefficient specifications should prioritize the MOS2CT52R331J.
