Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MOS2CT52R360J is determined by the following critical parameters:

• Resistance value: 36 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 2W (exact match required)
• Composition: Metal Oxide Film (exact match required)
• Package: Axial through-hole (exact match required)
• Operating temperature range: Minimum -55°C to +200°C coverage required
• RoHS compliance: ROHS3 Compliant (required for regulatory alignment)
• Termination count: 2 (exact match required)

The RSF200JB-73-36R from YAGEO meets all critical electrical and mechanical parameters, making it a valid substitute despite minor dimensional variations and extended upper operating temperature capability.

Engineering Selection Recommendations

Both the MOS2CT52R360J and RSF200JB-73-36R are active production components with ROHS3 compliance and unlimited moisture sensitivity ratings. Selection between these parts should be based on:

• PCB layout constraints: The MOS2CT52R360J features a more compact axial profile (4.00mm diameter, 12.00mm length) compared to the RSF200JB-73-36R (5.00mm diameter, 15.50mm length). Space-critical applications may require the KOA Speer component.
• Thermal requirements: The RSF200JB-73-36R supports operation to 235°C, providing 35°C additional margin above the MOS2CT52R360J specification of 200°C.
• Packaging format: The MOS2CT52R360J is supplied in Tape & Reel format, while the RSF200JB-73-36R is supplied in Bulk format. Procurement and assembly processes should align with available packaging.
• Inventory availability: Current stock levels differ between manufacturers and should be evaluated against project timelines.

Frequently Asked Questions (FAQ)

Q: Can RSF200JB-73-36R be used as a direct replacement for MOS2CT52R360J in all applications?

A: Yes, provided PCB layout accommodates the larger axial dimensions (5.00mm diameter vs. 4.00mm diameter). Both components meet identical electrical specifications for resistance, tolerance, power rating, and composition.

Q: What is the significance of the dimensional difference between these parts?

A: The RSF200JB-73-36R is physically larger in both diameter and length. PCB hole spacing, component clearance, and thermal management considerations must account for these differences. Verify mechanical fit before design implementation.

Q: Are there temperature-related limitations when substituting?

A: The RSF200JB-73-36R operates to 235°C versus the MOS2CT52R360J at 200°C. Both exceed typical application requirements. The MOS2CT52R360J temperature coefficient of ±300ppm/°C applies to the primary part; the substitute's temperature coefficient is not specified in available data.

Q: Do packaging format differences affect component performance?

A: No. Tape & Reel and Bulk packaging formats do not affect electrical or mechanical performance. Differences relate to procurement, storage, and assembly automation compatibility.

Q: Are both components suitable for safety-critical applications?

A: Both components feature safety characteristics and flame protection (retardant vs. proof rating). Regulatory and application-specific safety requirements must be independently verified.
