Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MOS2CT52R100J are classified based on electrical and mechanical parameter alignment. The primary substitution criteria are:

Critical Parameters for Substitution:

• Resistance value: 10 Ohms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Metal Oxide Film
• Package configuration: Axial through-hole
• RoHS compliance: ROHS3 Compliant

Parametric Equivalent Classification: The MOS2CT52A100J is a parametric equivalent manufactured by KOA Speer Electronics, Inc., sharing identical electrical specifications and package dimensions with the main part. This classification indicates full interchangeability for applications requiring the specified parameters.

Similar Manufacturer Classification: The RSF200JB-73-10R manufactured by YAGEO is classified as a similar part. While it maintains the same resistance, tolerance, power rating, and composition, it differs in physical dimensions (0.197" Dia x 0.610" L versus 0.157" Dia x 0.472" L) and operating temperature range (-55°C ~ 235°C versus -55°C ~ 200°C). These dimensional and thermal differences require evaluation for specific application constraints.

Parameter Comparison

Engineering Selection Recommendations

MOS2CT52A100J Selection: The MOS2CT52A100J is suitable for direct substitution in applications currently specified for the MOS2CT52R100J. Both parts are manufactured by KOA Speer Electronics, Inc., maintain identical electrical parameters, and share the same physical dimensions. Both parts are ROHS3 compliant and REACH unaffected. This part is recommended when KOA Speer sourcing is required or when inventory availability of the primary part is constrained.

RSF200JB-73-10R Selection: The RSF200JB-73-10R is suitable for applications where the electrical parameters (10 Ohms, ±5%, 2W, metal oxide film) are the primary selection criteria and physical dimensions are not constrained. The larger physical dimensions (0.197" Dia x 0.610" L) and extended operating temperature range (-55°C ~ 235°C) may provide advantages in thermal-demanding applications. This part is recommended when YAGEO sourcing is preferred or when higher inventory availability is required. PCB layout and mechanical clearance must be evaluated due to dimensional differences.

All substitute parts maintain ROHS3 compliance and REACH unaffected status, supporting regulatory requirements for restricted substance management.

Frequently Asked Questions (FAQ)

Q: Can MOS2CT52A100J be used as a direct replacement for MOS2CT52R100J?

A: Yes. The MOS2CT52A100J is a parametric equivalent with identical resistance (10 Ohms), tolerance (±5%), power rating (2W), composition (metal oxide film), package type (axial), operating temperature range (-55°C ~ 200°C), and physical dimensions (0.157" Dia x 0.472" L). Both parts are manufactured by KOA Speer Electronics, Inc., and are ROHS3 compliant.

Q: What are the key differences between MOS2CT52R100J and RSF200JB-73-10R?

A: The primary differences are manufacturer (KOA Speer versus YAGEO), physical dimensions (0.157" Dia x 0.472" L versus 0.197" Dia x 0.610" L), and operating temperature range (-55°C ~ 200°C versus -55°C ~ 235°C). Electrical parameters (resistance, tolerance, power rating, composition) are identical. The RSF200JB-73-10R is larger and supports higher maximum operating temperature.

Q: Are there PCB layout considerations when substituting with RSF200JB-73-10R?

A: Yes. The RSF200JB-73-10R has larger physical dimensions than the MOS2CT52R100J. PCB hole spacing, component clearance, and thermal management layout must be evaluated to ensure the larger resistor fits within the available space and does not interfere with adjacent components.

Q: Do all substitute parts meet the same regulatory compliance standards?

A: Yes. All listed parts (MOS2CT52R100J, MOS2CT52A100J, and RSF200JB-73-10R) are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for restricted substance management.

Q: Which substitute part offers the best inventory availability?

A: The RSF200JB-73-10R offers the highest inventory availability with 22,275 units in stock, compared to 3,675 units for MOS2CT52A100J and 1,994 units for MOS2CT52R100J. Inventory levels should be considered in procurement planning for supply chain continuity.

Q: Is temperature coefficient specification important for substitution?

A: The MOS2CT52R100J and MOS2CT52A100J both specify ±300ppm/°C temperature coefficient. The RSF200JB-73-10R does not provide temperature coefficient specification. For applications requiring precise temperature stability, the KOA Speer parts with specified temperature coefficient are preferred.
