Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MOS2CT52R822J is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 8.2 kOhms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Metal Oxide Film
• Package type: Axial
• Number of terminations: 2

Acceptable Variation Parameters:

• Operating temperature range: Substitute must meet or exceed the minimum and maximum operating temperatures of the primary part
• Physical dimensions: Substitute may differ within reasonable axial resistor standards
• Packaging format: Substitute may differ (Cut Tape vs. Bulk)
• Regulatory compliance: Substitute must maintain ROHS3 and REACH compliance status

The RSF200JB-73-8K2 from YAGEO meets all mandatory matching parameters and exceeds the operating temperature range specification, making it a valid substitute for the MOS2CT52R822J.

Parameter Comparison

Engineering Selection Recommendations

Both the MOS2CT52R822J and RSF200JB-73-8K2 are active production parts with full ROHS3 and REACH compliance. The RSF200JB-73-8K2 provides an extended operating temperature range to 235°C, offering enhanced thermal performance compared to the primary part's 200°C maximum.

Selection between these parts should be based on:

Primary Part (MOS2CT52R822J): Select when KOA Speer sourcing is preferred, when the compact 4.00mm diameter is required for space-constrained applications, or when the ±300ppm/°C temperature coefficient specification is a design requirement.

Substitute Part (RSF200JB-73-8K2): Select when YAGEO sourcing is preferred, when higher temperature operation to 235°C is beneficial, or when bulk packaging availability is advantageous for high-volume procurement. Note that the substitute part has larger physical dimensions (5.00mm diameter vs. 4.00mm), which must be verified for PCB layout compatibility.

Both parts are suitable for applications requiring 2W dissipation at 8.2 kOhms with ±5% tolerance across industrial temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can the RSF200JB-73-8K2 be used as a direct replacement for the MOS2CT52R822J in all applications?

A: The RSF200JB-73-8K2 is electrically equivalent and meets all mandatory specifications. However, the substitute part has larger physical dimensions (5.00mm diameter vs. 4.00mm diameter). PCB layout verification is required to confirm that the larger diameter does not create mechanical interference or violate spacing requirements in your specific application.

Q: What is the significance of the operating temperature range difference?

A: The MOS2CT52R822J operates from -55°C to 200°C, while the RSF200JB-73-8K2 operates from -55°C to 235°C. The substitute part's extended upper temperature limit provides additional thermal margin. If your application operates near or above 200°C, the substitute part offers enhanced reliability. If your application operates below 200°C, both parts are functionally equivalent in this parameter.

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts are ROHS3 compliant and REACH unaffected. No compliance differences exist between the primary and substitute parts.

Q: What is the difference between Cut Tape and Bulk packaging?

A: The MOS2CT52R822J is supplied in Cut Tape packaging, while the RSF200JB-73-8K2 is supplied in Bulk packaging. Cut Tape is typically used for smaller quantities and automated pick-and-place assembly. Bulk packaging is used for high-volume applications. Packaging format does not affect electrical or mechanical performance.

Q: Is the temperature coefficient specification important for my application?

A: The MOS2CT52R822J specifies a temperature coefficient of ±300ppm/°C. The RSF200JB-73-8K2 does not provide this specification in the available data. If your circuit design requires a specific temperature coefficient value, the primary part's specification should be used. If temperature coefficient is not a critical design parameter, the substitute part is acceptable.

Q: Can I use these parts interchangeably on the same PCB?

A: Electrical interchangeability is confirmed. Mechanical interchangeability requires verification of PCB layout. The substitute part's larger diameter (5.00mm vs. 4.00mm) and length (15.50mm vs. 12.00mm) must be confirmed to fit within the available PCB space and component placement constraints.
