Key Parameters

Substitute Part Grouping Explanation

Substitution of the MOS2CT52R273J is based on strict equivalence of the following electrical and mechanical parameters:

• Resistance Value: 27 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)
• Termination Count: 2 (exact match required)
• Regulatory Compliance: RoHS3 Compliant (minimum requirement)

The substitute part RSF200JB-73-27K from YAGEO meets all core electrical specifications and maintains mechanical compatibility as an axial through-hole resistor. Both parts are Active status products with RoHS3 compliance and REACH Unaffected status.

Parameter Comparison

Engineering Selection Recommendations

Both the MOS2CT52R273J and RSF200JB-73-27K are Active status products with full RoHS3 compliance and REACH Unaffected designation, meeting current regulatory requirements for electronic component applications.

The MOS2CT52R273J operates within a -55°C to 200°C temperature range with a temperature coefficient of ±300ppm/°C and features flame retardant coating. The RSF200JB-73-27K extends the upper operating temperature to 235°C with flame proof construction, providing enhanced thermal performance for applications requiring higher temperature operation.

Physical dimensions differ between the two parts. The MOS2CT52R273J measures 0.157" diameter by 0.472" length, while the RSF200JB-73-27K measures 0.197" diameter by 0.610" length. Component selection should account for available board space and layout constraints.

Both parts share identical electrical specifications: 27 kOhms resistance, ±5% tolerance, and 2W power rating in metal oxide film composition. Selection between these parts depends on thermal requirements, available physical space, and packaging format preference (Cut Tape versus Bulk).

Frequently Asked Questions (FAQ)

Q: Can the RSF200JB-73-27K replace the MOS2CT52R273J in all applications?

A: The RSF200JB-73-27K is electrically equivalent with identical resistance, tolerance, and power rating. However, physical dimensions differ. The RSF200JB-73-27K is larger (0.197" Dia x 0.610" L versus 0.157" Dia x 0.472" L), requiring verification of available board space. The extended operating temperature range of the RSF200JB-73-27K (-55°C to 235°C) provides additional thermal capability compared to the MOS2CT52R273J (-55°C to 200°C).

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

A: Substitution requires exact matching of resistance value (27 kOhms), tolerance (±5%), power rating (2W), and composition (metal oxide film). Both parts meet these criteria and are therefore electrically interchangeable.

Q: Are there packaging differences between these parts?

A: Yes. The MOS2CT52R273J is supplied in Cut Tape packaging, while the RSF200JB-73-27K is supplied in Bulk packaging. Both are axial through-hole components with identical termination configuration (2 terminations).

Q: Do both parts meet current compliance standards?

A: Both the MOS2CT52R273J and RSF200JB-73-27K are RoHS3 compliant and REACH Unaffected, meeting current regulatory requirements. Both carry EAR99 ECCN classification and 8533.21.0090 HTSUS code.

Q: What is the temperature coefficient difference?

A: The MOS2CT52R273J specifies a temperature coefficient of ±300ppm/°C. The RSF200JB-73-27K does not provide a temperature coefficient specification in the available data.

Q: How do the physical dimensions affect component selection?

A: The RSF200JB-73-27K is physically larger in both diameter and length. Applications with space constraints may require the smaller MOS2CT52R273J. Conversely, applications with adequate board space can accommodate the RSF200JB-73-27K, which offers extended temperature range capability.
