Key Parameters

Substitute Part Grouping Explanation

Substitution of the ROX2SJ8K2 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 8.2 kOhms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Metal Oxide Film

Mechanical Parameters:

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

Compliance Parameters:

• RoHS3 compliance status
• REACH unaffected classification
• ECCN and HTSUS alignment

The substitute part RSF200JB-73-8K2 meets all critical electrical and mechanical requirements. Physical dimensions vary slightly between the main part and substitute, with the substitute featuring a longer body length (15.50mm vs. 12.00mm). Both parts maintain identical resistance, tolerance, power rating, and composition specifications. Operating temperature range extends to 235°C for the substitute compared to 200°C for the main part, providing enhanced thermal capability.

Parameter Comparison

Engineering Selection Recommendations

Both the ROX2SJ8K2 and RSF200JB-73-8K2 are active production parts with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component deployment.

Primary Part Selection (ROX2SJ8K2): Select the ROX2SJ8K2 when cut tape packaging is required for automated assembly processes or when the shorter body length (12.00mm) is necessary for space-constrained applications. The specified temperature coefficient of ±350ppm/°C provides documented thermal stability characteristics.

Substitute Part Selection (RSF200JB-73-8K2): Select the RSF200JB-73-8K2 when bulk packaging is acceptable or preferred for high-volume applications. The extended operating temperature range to 235°C provides additional thermal margin for applications operating at elevated temperatures. The significantly higher inventory level (22295 pieces) supports rapid procurement and reduced lead times.

Both parts satisfy identical electrical specifications and mechanical form factors. Selection between them is determined by packaging requirements, inventory availability, and thermal operating envelope needs.

Frequently Asked Questions (FAQ)

Q: Can RSF200JB-73-8K2 be used as a direct replacement for ROX2SJ8K2 in existing circuit designs?

A: Yes. Both parts share identical resistance (8.2 kOhms), tolerance (±5%), power rating (2W), composition (metal oxide film), and axial package configuration. The primary consideration is physical length: RSF200JB-73-8K2 measures 15.50mm compared to 12.00mm for ROX2SJ8K2. Verify that the longer body length accommodates the available board space in your application.

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

A: The ROX2SJ8K2 operates from -55°C to 200°C, while RSF200JB-73-8K2 extends to 235°C. For applications operating below 200°C, both parts are equivalent. For applications requiring operation between 200°C and 235°C, only RSF200JB-73-8K2 is suitable.

Q: How do packaging differences affect component selection?

A: ROX2SJ8K2 is supplied in cut tape (CT) packaging, suitable for automated pick-and-place assembly. RSF200JB-73-8K2 is supplied in bulk packaging, typically used for manual assembly or high-volume reel-based automated processes. Select based on your assembly method and handling requirements.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both ROX2SJ8K2 and RSF200JB-73-8K2 are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations for electronic components.

Q: What is the temperature coefficient specification for RSF200JB-73-8K2?

A: The temperature coefficient for RSF200JB-73-8K2 is not specified in the available technical data. The ROX2SJ8K2 specifies ±350ppm/°C. If precise temperature coefficient documentation is required for your application, contact the manufacturer directly.

Q: Which part should be selected for new designs?

A: For new designs, either part is acceptable based on your specific requirements. If automated assembly with cut tape packaging is planned, select ROX2SJ8K2. If bulk packaging or extended temperature operation to 235°C is required, select RSF200JB-73-8K2. Both parts are active production items with established supply chains.
