Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MOS2CT52R163J is determined by strict equivalence across the following critical parameters:

• Resistance value: 16 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 2W (exact match required)
• Composition: Metal Oxide Film (exact match required)
• Package configuration: Axial through-hole (exact match required)
• Operating temperature range: Minimum -55°C to maximum 200°C or higher
• RoHS compliance: ROHS3 Compliant (mandatory for regulatory equivalence)
• Termination count: 2 (exact match required)

The RSF200JB-73-16K from YAGEO meets all substitution criteria and qualifies as a direct equivalent part.

Parameter Comparison

Engineering Selection Recommendations

Both the MOS2CT52R163J and RSF200JB-73-16K are Active product status components with full ROHS3 compliance certification. The RSF200JB-73-16K provides an extended operating temperature range of -55°C to 235°C compared to the MOS2CT52R163J range of -55°C to 200°C, offering additional thermal margin in high-temperature applications. Both components carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related handling restrictions. Selection between these parts should be based on packaging availability, procurement lead times, and specific thermal requirements of the application circuit.

Frequently Asked Questions (FAQ)

Q: Can the RSF200JB-73-16K replace the MOS2CT52R163J in all applications?

A: Yes, the RSF200JB-73-16K is electrically and mechanically equivalent to the MOS2CT52R163J. Both components share identical resistance value, tolerance, power rating, composition, and axial package configuration. The RSF200JB-73-16K provides an extended operating temperature range, making it suitable for all applications where the MOS2CT52R163J is specified.

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

A: The MOS2CT52R163J measures 0.157" diameter × 0.472" length (4.00mm × 12.00mm). The RSF200JB-73-16K measures 0.197" diameter × 0.610" length (5.00mm × 15.50mm). Physical layout considerations may apply in space-constrained designs.

Q: Are both parts RoHS compliant?

A: Yes, both the MOS2CT52R163J and RSF200JB-73-16K are ROHS3 compliant, meeting current regulatory requirements for electronic component manufacturing and assembly.

Q: What is the significance of the ±300ppm/°C temperature coefficient?

A: The temperature coefficient of ±300ppm/°C for the MOS2CT52R163J indicates the maximum resistance change per degree Celsius across the operating temperature range. This specification is critical for precision analog circuits where temperature stability is required. The RSF200JB-73-16K temperature coefficient is not specified in available documentation.

Q: Can these parts be used interchangeably in PCB designs?

A: Electrical substitution is direct. However, physical layout differences require verification. The RSF200JB-73-16K is larger in both diameter and length, which may affect PCB routing and component placement in compact designs. Mechanical clearance validation is recommended before production implementation.
