Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MOSX2CT52RR82J is determined by strict alignment of the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 820 mOhms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Metal Oxide Film

Mechanical Compatibility Requirements:

• Package configuration: Axial through-hole
• Number of terminations: 2
• Physical form factor: Axial lead configuration

Regulatory and Compliance Requirements:

• RoHS3 compliance status
• REACH unaffected designation
• ECCN classification: EAR99

Substitute parts must satisfy all electrical specifications and maintain mechanical compatibility with the original PCB footprint and assembly process. Regulatory compliance status must be equivalent or superior to the original component.

Parameter Comparison

Engineering Selection Recommendations

The RSF200JB-73-0R82 manufactured by YAGEO qualifies as a direct electrical substitute for the MOSX2CT52RR82J. Both components share identical resistance values, tolerance specifications, power ratings, and metal oxide film composition. Both maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent applications.

The YAGEO RSF200JB-73-0R82 provides an extended operating temperature range of -55°C to 235°C compared to the KOA Speer component's -55°C to 200°C range, offering enhanced thermal performance in high-temperature environments. Both components are rated for 2-watt dissipation and feature axial lead configurations suitable for through-hole PCB assembly.

Physical dimensions differ between the two components. The YAGEO substitute exhibits larger overall dimensions (0.197" diameter × 0.610" length versus 0.157" diameter × 0.472" length). PCB layout verification is necessary to confirm that the larger physical footprint accommodates existing board spacing and component placement constraints.

Both components maintain Active product status with confirmed inventory availability, ensuring supply chain continuity for production applications.

Frequently Asked Questions (FAQ)

Q: Can the RSF200JB-73-0R82 be used as a direct replacement for the MOSX2CT52RR82J in all applications?

A: The RSF200JB-73-0R82 satisfies all electrical specifications and regulatory requirements for substitution. However, the larger physical dimensions (0.197" diameter × 0.610" length versus 0.157" diameter × 0.472" length) require verification against PCB layout constraints, component spacing, and assembly clearances before implementation.

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitution eligibility is determined by matching resistance value (820 mOhms), tolerance (±5%), power rating (2W), and composition (metal oxide film). Both the MOSX2CT52RR82J and RSF200JB-73-0R82 meet these criteria.

Q: Are there compliance differences between the two components?

A: Both components maintain ROHS3 compliance and REACH unaffected status. Both are classified under ECCN EAR99. No compliance disadvantages exist for the YAGEO substitute.

Q: How do the operating temperature ranges compare?

A: The MOSX2CT52RR82J operates from -55°C to 200°C, while the RSF200JB-73-0R82 operates from -55°C to 235°C. The YAGEO component provides a 35-degree Celsius extended upper temperature limit, suitable for applications requiring enhanced thermal performance.

Q: What packaging differences exist between these components?

A: The MOSX2CT52RR82J is supplied in Cut Tape (CT) packaging, while the RSF200JB-73-0R82 is supplied in Bulk packaging. This distinction affects procurement and handling procedures but does not impact electrical or mechanical compatibility.

Q: Is the temperature coefficient specification critical for substitution?

A: The MOSX2CT52RR82J specifies a temperature coefficient of ±300ppm/°C. The RSF200JB-73-0R82 does not provide this specification in the available data. For applications where temperature coefficient performance is critical, this parameter difference requires evaluation against specific circuit requirements.
