Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MOS2CT52R820J is determined by matching the following critical parameters:

Electrical Parameters (Must Match):

• Resistance value: 82 Ohms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Metal Oxide Film

Mechanical Parameters (Must Match):

• Package type: Axial through-hole
• Number of terminations: 2

Compliance Parameters (Must Match or Exceed):

• RoHS3 Compliant status
• REACH Unaffected status

The substitute part RSF200JB-73-82R from YAGEO meets all critical electrical and mechanical parameters. Both parts are metal oxide film axial resistors with identical resistance, tolerance, and power ratings. Both maintain RoHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across applications.

Engineering Selection Recommendations

Primary Part: MOS2CT52R820J

The MOS2CT52R820J remains the preferred selection when available. This KOA Speer Electronics part is Active in product status with established inventory (1770 pieces in stock). The part carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The flame retardant coating and safety construction provide specified protection characteristics.

Substitute Part: RSF200JB-73-82R

The RSF200JB-73-82R from YAGEO is a qualified substitute when the primary part is unavailable. This part maintains electrical equivalence across all critical parameters: 82 Ohm resistance, ±5% tolerance, and 2W power rating. Both parts employ metal oxide film composition with axial through-hole packaging. The substitute part exceeds the primary part's operating temperature range (-55°C ~ 235°C versus -55°C ~ 200°C), providing enhanced thermal performance. Both parts maintain ROHS3 compliance and REACH unaffected status.

Physical Dimension Consideration:

The RSF200JB-73-82R has larger physical dimensions (0.197" Dia x 0.610" L) compared to the MOS2CT52R820J (0.157" Dia x 0.472" L). PCB layout and mechanical clearance must accommodate the larger axial body. This dimensional difference does not affect electrical performance but requires verification of available board space during component placement.

Frequently Asked Questions (FAQ)

Q: Can RSF200JB-73-82R replace MOS2CT52R820J in all applications?

A: RSF200JB-73-82R is electrically equivalent to MOS2CT52R820J across all critical parameters: resistance value, tolerance, power rating, and composition. Both are metal oxide film axial resistors with identical electrical specifications. Physical dimensions differ, requiring verification that PCB layout accommodates the larger substitute body.

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

A: Substitution requires matching of resistance value (82 Ohms), tolerance (±5%), power rating (2W), and composition (metal oxide film). These parameters determine functional equivalence in circuit operation.

Q: Are both parts compliant with current regulations?

A: Both MOS2CT52R820J and RSF200JB-73-82R are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component use.

Q: What is the difference in operating temperature ranges?

A: MOS2CT52R820J operates from -55°C to 200°C, while RSF200JB-73-82R operates from -55°C to 235°C. The substitute part provides a wider upper temperature limit, offering enhanced thermal performance in high-temperature applications.

Q: How do the physical dimensions affect component selection?

A: MOS2CT52R820J measures 0.157" Dia x 0.472" L (4.00mm x 12.00mm), while RSF200JB-73-82R measures 0.197" Dia x 0.610" L (5.00mm x 15.50mm). The substitute part is larger in both diameter and length. PCB layout, component spacing, and mechanical clearance must be verified before substitution to ensure proper fit within the available board space.

Q: What packaging formats are available for these parts?

A: MOS2CT52R820J is supplied in Cut Tape (CT) packaging, while RSF200JB-73-82R is supplied in Bulk packaging. Packaging format affects inventory management and component handling but does not impact electrical or mechanical performance.

Q: Are there any temperature coefficient differences between these parts?

A: MOS2CT52R820J specifies a temperature coefficient of ±300ppm/°C. Temperature coefficient data for RSF200JB-73-82R is not provided in the available specifications.
