Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MOS2CT52R473J is determined by the following critical parameters:

Electrical Parameters (Must Match):

• Resistance value: 47 kOhms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Metal Oxide Film

Mechanical Parameters (Must Match):

• Package type: Axial
• Number of terminations: 2
• Through-hole configuration

Compliance Parameters (Must Match or Exceed):

• RoHS3 Compliant status
• REACH Unaffected status

Operating Conditions (Must Support):

• Operating temperature range minimum: -55°C
• Operating temperature range maximum: 200°C or higher

The substitute parts ROX2SJ47K (TE Connectivity Passive Product) and RSF200JB-73-47K (YAGEO) meet all critical electrical and mechanical parameters. Both are metal oxide film axial resistors with 47 kOhms resistance, ±5% tolerance, and 2W power rating. Both maintain ROHS3 compliance and REACH Unaffected status. Physical dimensions vary slightly between manufacturers, but all parts conform to standard axial package specifications suitable for PCB mounting in equivalent footprints.

Parameter Comparison

Engineering Selection Recommendations

All three parts—MOS2CT52R473J, ROX2SJ47K, and RSF200JB-73-47K—are active products with full ROHS3 compliance and REACH Unaffected status, making them suitable for applications subject to environmental and regulatory requirements.

MOS2CT52R473J (KOA Speer Electronics, Inc.): Primary choice when KOA Speer sourcing is specified or preferred. Offers the smallest physical diameter (4.00mm) and shortest length (12.00mm), advantageous for space-constrained PCB layouts. Temperature coefficient of ±300ppm/°C provides tighter stability. Available in Cut Tape packaging with 2063 units in stock.

ROX2SJ47K (TE Connectivity Passive Product): Direct substitute with identical electrical specifications and operating temperature range. Slightly larger diameter (5.00mm) and equivalent length (12.00mm). Temperature coefficient of ±350ppm/°C is within acceptable tolerance for most applications. Features pulse withstanding capability. Available in Cut Tape packaging with 5916 units in stock.

RSF200JB-73-47K (YAGEO): Suitable substitute with extended operating temperature range to 235°C, providing additional thermal margin. Larger physical dimensions (5.00mm diameter, 15.50mm length) require verification of PCB layout compatibility. Available in Bulk packaging with 5916 units in stock.

Selection should prioritize the MOS2CT52R473J for direct replacement. ROX2SJ47K serves as the primary equivalent substitute. RSF200JB-73-47K is acceptable where extended temperature operation is beneficial and physical dimensions do not conflict with board layout constraints.

Frequently Asked Questions (FAQ)

Q: Can ROX2SJ47K be used as a direct replacement for MOS2CT52R473J?

A: Yes. Both parts share identical electrical specifications: 47 kOhms resistance, ±5% tolerance, and 2W power rating. Both are metal oxide film axial resistors with equivalent operating temperature ranges (-55°C to 200°C). Physical dimensions differ slightly (ROX2SJ47K is 5.00mm diameter versus 4.00mm for MOS2CT52R473J), but both conform to standard axial package footprints suitable for equivalent PCB mounting.

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

A: MOS2CT52R473J measures 0.157" diameter × 0.472" length (4.00mm × 12.00mm). ROX2SJ47K measures 0.197" diameter × 0.472" length (5.00mm × 12.00mm). RSF200JB-73-47K measures 0.197" diameter × 0.610" length (5.00mm × 15.50mm). The MOS2CT52R473J is the most compact. ROX2SJ47K matches the length but has a larger diameter. RSF200JB-73-47K is the longest. PCB layout verification is required when substituting with larger dimensions.

Q: Are all three parts RoHS3 compliant?

A: Yes. MOS2CT52R473J, ROX2SJ47K, and RSF200JB-73-47K are all ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards for electronic components.

Q: What is the temperature coefficient difference, and does it matter?

A: MOS2CT52R473J has a temperature coefficient of ±300ppm/°C, while ROX2SJ47K is ±350ppm/°C. RSF200JB-73-47K does not specify this parameter. The difference of 50ppm/°C is negligible for most applications. Selection should be based on application-specific stability requirements and operating temperature range.

Q: Can RSF200JB-73-47K be used in applications requiring operation above 200°C?

A: RSF200JB-73-47K supports operating temperatures up to 235°C, compared to 200°C for MOS2CT52R473J and ROX2SJ47K. This extended range makes RSF200JB-73-47K suitable for high-temperature applications. However, its larger physical dimensions (15.50mm length) must be verified against PCB layout constraints before selection.

Q: What packaging formats are available?

A: MOS2CT52R473J and ROX2SJ47K are supplied in Cut Tape (CT) packaging. RSF200JB-73-47K is supplied in Bulk packaging. Cut Tape format is standard for automated assembly processes, while Bulk packaging is suitable for manual assembly or reel-based operations.

Q: Are all parts currently in stock?

A: Yes. MOS2CT52R473J has 2063 units in stock. ROX2SJ47K has 5916 units in stock. RSF200JB-73-47K has 5916 units in stock. All parts are listed as Active products in current production.
