Parameter Comparison

Engineering Selection Recommendations

Both the MOS2CT52R683J and RSF200JB-73-68K meet the core electrical requirements for 68 kOhms ±5% 2W axial resistor applications. Selection between these components should be based on the following factors:

MOS2CT52R683J (KOA Speer): Select this component when cut tape packaging is required for automated assembly processes. The compact physical dimensions (4.00mm diameter x 12.00mm length) are suitable for space-constrained applications. Operating temperature range extends to 200°C.

RSF200JB-73-68K (YAGEO): Select this component when bulk packaging is acceptable or preferred for manual assembly or when higher operating temperature capability (235°C maximum) is required. The larger physical dimensions (5.00mm diameter x 15.50mm length) may be relevant for thermal dissipation considerations in high-temperature environments.

Both components are Active status products with ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance for current manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can the RSF200JB-73-68K replace the MOS2CT52R683J in all applications?

A: The RSF200JB-73-68K is electrically equivalent to the MOS2CT52R683J for applications requiring 68 kOhms ±5% 2W resistance. Physical dimensions differ; the RSF200JB-73-68K is larger (5.00mm x 15.50mm versus 4.00mm x 12.00mm). Verify that the larger size accommodates your PCB layout and thermal requirements.

Q: What is the difference in packaging between these two parts?

A: The MOS2CT52R683J is supplied in Cut Tape (CT) packaging, suitable for automated pick-and-place assembly. The RSF200JB-73-68K is supplied in Bulk packaging, typically used for manual assembly or tape-and-reel conversion processes.

Q: Are both parts RoHS compliant?

A: Yes, both the MOS2CT52R683J and RSF200JB-73-68K are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the temperature coefficient difference?

A: The MOS2CT52R683J specifies a temperature coefficient of ±300ppm/°C. The RSF200JB-73-68K does not provide a temperature coefficient specification in the available data. For applications with strict temperature stability requirements, the MOS2CT52R683J provides documented performance characteristics.

Q: Can I use the RSF200JB-73-68K in applications exceeding 200°C?

A: The RSF200JB-73-68K has an operating temperature range of -55°C to 235°C, compared to the MOS2CT52R683J range of -55°C to 200°C. The RSF200JB-73-68K is suitable for applications requiring operation above 200°C up to 235°C.

Q: Are the electrical specifications identical between these parts?

A: Yes, both components share identical electrical specifications: 68 kOhms resistance, ±5% tolerance, 2W power rating, metal oxide film composition, and 2 terminations. Both are ROHS3 compliant with EAR99 ECCN classification.
