Key Parameters

Substitute Part Grouping Explanation

Substitution of the MOS2CT52R272J with the RSF200JB-73-2K7 is based on the following matched electrical and mechanical parameters:

Matched Electrical Specifications:

• Resistance value: 2.7 kOhms (identical)
• Tolerance: ±5% (identical)
• Power rating: 2W (identical)
• Composition: Metal Oxide Film (identical)

Matched Mechanical Specifications:

• Package type: Axial (identical)
• Number of terminations: 2 (identical)

Matched Compliance:

• RoHS3 Compliant (both parts)
• REACH Unaffected (both parts)
• ECCN: EAR99 (both parts)
• HTSUS: 8533.21.0090 (both parts)

The RSF200JB-73-2K7 operates across an extended temperature range (-55°C ~ 235°C) compared to the MOS2CT52R272J (-55°C ~ 200°C), providing broader environmental compatibility. Both parts feature safety-rated construction with flame protection characteristics suitable for equivalent circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the MOS2CT52R272J and RSF200JB-73-2K7 are active production components with full RoHS3 and REACH compliance, suitable for equivalent circuit applications. Selection between these parts should be based on the following engineering considerations:

MOS2CT52R272J Selection Criteria:

• Preferred when compact axial dimensions (4.00mm diameter x 12.00mm length) are required for space-constrained PCB layouts
• Specified temperature coefficient of ±300ppm/°C is available for precision circuit calculations
• KOA Speer Electronics manufacturing source preferred for specific supply chain requirements

RSF200JB-73-2K7 Selection Criteria:

• Extended operating temperature range (-55°C ~ 235°C) accommodates applications requiring higher maximum temperature operation
• Larger physical dimensions (5.00mm diameter x 15.50mm length) may require PCB layout verification
• YAGEO manufacturing source provides alternative supply chain option with higher inventory availability (14190 pieces)

Both parts maintain identical electrical performance in resistance value, tolerance, power rating, and composition. Substitution is electrically and mechanically valid when dimensional constraints and temperature requirements are satisfied by the selected part.

Frequently Asked Questions (FAQ)

Q: Can the RSF200JB-73-2K7 directly replace the MOS2CT52R272J in existing designs?

A: Electrical substitution is valid when the extended operating temperature range (-55°C ~ 235°C) and larger physical dimensions (5.00mm diameter x 15.50mm length) are compatible with the application. PCB layout verification is required to confirm the substitute part fits within available mounting space.

Q: What are the critical electrical parameters that must match for substitution?

A: The following parameters must be identical: resistance value (2.7 kOhms), tolerance (±5%), power rating (2W), composition (metal oxide film), and package type (axial). All four parameters are matched between these parts.

Q: Are there compliance differences between these two parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS codes. No compliance barriers exist for substitution.

Q: What is the primary dimensional difference between these parts?

A: The MOS2CT52R272J measures 4.00mm diameter x 12.00mm length, while the RSF200JB-73-2K7 measures 5.00mm diameter x 15.50mm length. The substitute part is physically larger and requires confirmation of available PCB mounting space.

Q: Is temperature coefficient information available for the RSF200JB-73-2K7?

A: Temperature coefficient data is not provided for the RSF200JB-73-2K7. The MOS2CT52R272J specifies ±300ppm/°C. Contact the manufacturer for detailed temperature coefficient specifications if this parameter is critical to circuit performance.

Q: What inventory considerations apply to these parts?

A: The MOS2CT52R272J has 2170 pieces in stock, while the RSF200JB-73-2K7 has 14190 pieces available. The substitute part offers significantly higher inventory availability for applications with extended lead time requirements.
