Key Parameters

Substitute Part Grouping Explanation

Substitution of the MOS2CT52R681J is permissible with parts meeting the following criteria:

Electrical Parameters (Critical for Substitution):

• Resistance value: 680 Ohms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Metal Oxide Film

Mechanical Parameters (Required for Compatibility):

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

Compliance Parameters (Required for Regulatory Compatibility):

• RoHS3 Compliant status
• REACH Unaffected status

The substitute part RSF200JB-73-680R from YAGEO meets all critical electrical and mechanical parameters. Physical dimensions differ between the main part and substitute, with the substitute featuring a larger diameter (0.197" vs 0.157") and length (0.610" vs 0.472"). Operating temperature range extends to 235°C for the substitute compared to 200°C for the main part. Both parts maintain identical resistance, tolerance, power rating, and composition specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the MOS2CT52R681J and RSF200JB-73-680R are Active products with full RoHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic component deployment.

Selection Considerations Based on Provided Data:

The MOS2CT52R681J offers a compact form factor with smaller physical dimensions (0.157" diameter, 0.472" length) and operates within the -55°C to 200°C temperature range with a specified temperature coefficient of ±300ppm/°C.

The RSF200JB-73-680R substitute provides extended operating temperature capability to 235°C with larger physical dimensions (0.197" diameter, 0.610" length). This substitute is suitable for applications where the extended upper temperature limit provides operational margin or where board space constraints are not limiting factors.

Both parts maintain identical electrical specifications: 680 Ohms resistance, ±5% tolerance, and 2W power rating in metal oxide film composition. Component selection between these parts depends on specific application requirements regarding physical space availability, thermal operating conditions, and packaging format preferences (Cut Tape versus Bulk).

Frequently Asked Questions (FAQ)

Q: Can RSF200JB-73-680R be used as a direct replacement for MOS2CT52R681J?

A: Yes, the RSF200JB-73-680R meets all critical electrical and mechanical substitution criteria. Both parts are 680 Ohms ±5% 2W axial metal oxide film resistors with identical electrical performance. Physical dimensions differ, requiring verification of available board space. Both parts are RoHS3 compliant and REACH unaffected.

Q: What are the physical dimension differences between these parts?

A: The MOS2CT52R681J measures 0.157" diameter by 0.472" length (4.00mm x 12.00mm). The RSF200JB-73-680R measures 0.197" diameter by 0.610" length (5.00mm x 15.50mm). The substitute is larger in both dimensions and requires verification of available mounting space on the circuit board.

Q: Are there temperature range differences that affect substitution?

A: The MOS2CT52R681J operates from -55°C to 200°C. The RSF200JB-73-680R operates from -55°C to 235°C. The substitute provides extended upper temperature capability. For applications operating below 200°C, both parts are functionally equivalent in this parameter.

Q: Do both parts meet current compliance standards?

A: Yes, both the MOS2CT52R681J and RSF200JB-73-680R are RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component use.

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

A: The MOS2CT52R681J is supplied in Cut Tape (CT) packaging format. The RSF200JB-73-680R is supplied in Bulk packaging. Packaging format affects handling, storage, and automated assembly compatibility. Verify that your assembly process supports the substitute packaging format.

Q: Are the electrical specifications identical between these parts?

A: Yes, both parts share identical electrical specifications: 680 Ohms resistance, ±5% tolerance, 2W power rating, and metal oxide film composition. The MOS2CT52R681J specifies a temperature coefficient of ±300ppm/°C; the RSF200JB-73-680R temperature coefficient is not specified in available data.
