MOS2CT52R393J Equivalent & Substitute Parts

Part Overview

The MOS2CT52R393J is a 39 kOhms ±5% 2W through-hole resistor manufactured by KOA Speer Electronics, Inc. This axial metal oxide film resistor features flame retardant coating and safety construction, designed for applications requiring reliable performance across industrial temperature ranges. The part maintains Active product status with 2696 units in current inventory stock.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same resistance value, tolerance, power rating, and package type. Alternative sources provide continuity of supply and design flexibility while preserving circuit performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MOS2CT52R393J is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 39 kOhms (exact match)
• Tolerance: ±5% (exact match)
• Power rating: 2W (exact match)
• Composition: Metal Oxide Film (exact match)

Mechanical Compatibility Requirements:

• Package type: Axial (exact match)
• Number of terminations: 2 (exact match)
• Through-hole configuration (exact match)

Compliance Requirements:

• RoHS3 Compliant status (maintained)
• REACH Unaffected status (maintained)
• ECCN and HTSUS classifications (maintained)

The RSF200JB-73-39K from YAGEO meets all electrical and mechanical equivalence criteria. Physical dimensions vary between the main part and substitute, which is acceptable provided the axial package type and through-hole termination remain consistent with circuit board layout requirements.

Parameter Comparison

Engineering Selection Recommendations

MOS2CT52R393J (KOA Speer Electronics, Inc.):

• Primary selection for applications with strict spatial constraints due to smaller axial dimensions (4.00mm diameter, 12.00mm length)
• Active product status with established supply chain (2696 units in stock)
• ROHS3 and REACH compliant for regulated markets
• Temperature coefficient specification provided (±300ppm/°C)

RSF200JB-73-39K (YAGEO):

• Suitable substitute when spatial constraints are not limiting
• Extended operating temperature range (-55°C ~ 235°C) provides margin above primary part specification (-55°C ~ 200°C)
• Active product status with higher inventory availability (4249 units in stock)
• ROHS3 and REACH compliant for regulated markets
• Larger physical dimensions (5.00mm diameter, 15.50mm length) require board layout verification

Both parts maintain equivalent electrical performance and regulatory compliance. Selection between primary and substitute part depends on circuit board layout requirements and dimensional constraints specific to the application.

Frequently Asked Questions (FAQ)

Q: Can RSF200JB-73-39K replace MOS2CT52R393J in existing designs?

A: Electrical substitution is valid. The RSF200JB-73-39K provides identical resistance (39 kOhms), tolerance (±5%), power rating (2W), and composition (metal oxide film). However, physical dimensions differ: RSF200JB-73-39K measures 5.00mm diameter x 15.50mm length compared to MOS2CT52R393J at 4.00mm diameter x 12.00mm length. Circuit board layout must accommodate the larger axial package before substitution.

Q: Are there temperature performance differences between these parts?

A: The RSF200JB-73-39K operates across -55°C ~ 235°C, extending 35°C above the MOS2CT52R393J specification of -55°C ~ 200°C. Both parts function within standard industrial temperature ranges. The MOS2CT52R393J provides a specified temperature coefficient of ±300ppm/°C; the RSF200JB-73-39K temperature coefficient is not provided in available documentation.

Q: Do both parts meet regulatory requirements?

A: Yes. Both MOS2CT52R393J and RSF200JB-73-39K are ROHS3 Compliant and REACH Unaffected, meeting current environmental and hazardous substance regulations. Both carry identical ECCN (EAR99) and HTSUS (8533.21.0090) classifications.

Q: What packaging differences exist between these parts?

A: MOS2CT52R393J is supplied in Cut Tape (CT) packaging with 2696 units in stock. RSF200JB-73-39K is supplied in Bulk packaging with 4249 units in stock. Both are axial through-hole components with 2 terminations suitable for standard PCB assembly processes.

Q: Can I use these parts interchangeably in high-reliability applications?

A: Both parts are Active products from established manufacturers with ROHS3 compliance. Electrical specifications are equivalent. Interchangeability depends on physical space availability on the circuit board. Verify that the larger RSF200JB-73-39K dimensions (5.00mm x 15.50mm) do not conflict with component placement or thermal management requirements in your specific application.
