Key Parameters

Substitute Part Grouping Explanation

Substitution of the MOS2CT52R200J is permissible with the RSF200JB-73-20R based on the following critical parameters:

Electrical Equivalence:

• Identical resistance value: 20 Ohms
• Identical tolerance: ±5%
• Identical power rating: 2W
• Identical composition: Metal Oxide Film
• Both components feature safety design characteristics

Mechanical Compatibility:

• Both utilize axial through-hole package configuration
• Both feature two terminations for direct PCB mounting
• Both are suitable for standard axial component placement

Regulatory Compliance:

• Both are RoHS3 compliant
• Both are REACH unaffected
• Both share identical ECCN and HTSUS classifications

The RSF200JB-73-20R operates at an extended upper temperature limit of 235°C compared to the MOS2CT52R200J at 200°C, providing broader thermal operating capability while maintaining all other electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the MOS2CT52R200J and RSF200JB-73-20R are Active product status components with full RoHS3 compliance and REACH unaffected status, qualifying them for equivalent circuit applications.

The MOS2CT52R200J operates within a -55°C to 200°C temperature range with a temperature coefficient of ±300ppm/°C. The RSF200JB-73-20R extends the upper operating temperature to 235°C, providing additional thermal margin for applications requiring elevated temperature performance.

Physical dimensions differ between the two components. The MOS2CT52R200J measures 4.00mm diameter by 12.00mm length, while the RSF200JB-73-20R measures 5.00mm diameter by 15.50mm length. PCB layout and component spacing must accommodate the larger YAGEO component dimensions.

Both components maintain identical electrical specifications: 20 Ohms resistance, ±5% tolerance, and 2W power rating. Selection between these components depends on thermal requirements and available PCB space for component placement.

Frequently Asked Questions (FAQ)

Q: Can the RSF200JB-73-20R directly replace the MOS2CT52R200J in all applications?

A: Direct electrical replacement is valid for applications operating within the -55°C to 200°C range. The RSF200JB-73-20R provides extended temperature capability to 235°C. Physical dimensions differ; verify PCB layout accommodates the larger 5.00mm diameter and 15.50mm length of the YAGEO component.

Q: What are the key electrical parameters that must match for substitution?

A: Resistance value (20 Ohms), tolerance (±5%), power rating (2W), and composition (Metal Oxide Film) must remain identical. Both components satisfy these requirements.

Q: Are there compliance differences between these components?

A: Both components are RoHS3 compliant and REACH unaffected. ECCN and HTSUS classifications are identical. No compliance barriers exist for substitution.

Q: How do the physical dimensions affect component selection?

A: The MOS2CT52R200J (4.00mm x 12.00mm) is more compact than the RSF200JB-73-20R (5.00mm x 15.50mm). PCB designs with tight component spacing may require the smaller KOA Speer component. Designs with available space can accommodate either component.

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

A: Both designations indicate safety design characteristics. The MOS2CT52R200J features flame retardant coating; the RSF200JB-73-20R features flame proof design. Both meet safety requirements for their respective operating conditions.

Q: Does the temperature coefficient difference affect substitution?

A: The MOS2CT52R200J specifies ±300ppm/°C temperature coefficient. The RSF200JB-73-20R temperature coefficient is not provided in the specification data. For applications requiring precise temperature coefficient matching, verify YAGEO specifications independently.

Q: What packaging formats are available for these components?

A: The MOS2CT52R200J is supplied in Cut Tape (CT) packaging. The RSF200JB-73-20R is supplied in Bulk packaging. Procurement and handling procedures differ based on packaging format.
