Substitute Part Grouping Explanation

Substitution of the MOS2CT52R240J is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 24 Ohms (exact match required)
• Tolerance: ±5% (identical specification)
• Power rating: 2W (identical specification)
• Composition: Metal Oxide Film (identical material type)

Mechanical Compatibility Requirements:

• Package configuration: Axial through-hole (identical form factor)
• Number of terminations: 2 (identical pin count)

Regulatory and Compliance Requirements:

• RoHS3 Compliance (mandatory for substitution)
• REACH Unaffected status (mandatory for substitution)
• ECCN classification: EAR99 (identical export control)

The substitute part RSF200JB-73-24R meets all electrical and mechanical equivalence criteria while maintaining full regulatory compliance. Physical dimensions differ slightly between the main part and substitute, but both conform to standard axial resistor form factors suitable for through-hole PCB mounting.

Engineering Selection Recommendations

Primary Part Selection (MOS2CT52R240J): The MOS2CT52R240J remains the preferred selection when KOA Speer Electronics supply chain availability is confirmed and design specifications do not require extended temperature operation beyond 200°C. This part carries active product status with established manufacturing continuity.

Substitute Part Selection (RSF200JB-73-24R): The RSF200JB-73-24R from YAGEO is a direct electrical and mechanical substitute suitable for applications where:

• Extended operating temperature capability to 235°C is beneficial
• YAGEO supply chain availability is preferred or required
• Physical dimension variance (larger axial body) is accommodated within PCB layout constraints
• Bulk packaging format aligns with procurement requirements

Both parts maintain identical RoHS3 and REACH compliance status, ensuring regulatory equivalence for end-use applications. The substitute part carries active product status with higher inventory availability (8,920 pieces).

Frequently Asked Questions (FAQ)

Q: Can RSF200JB-73-24R be used as a direct replacement for MOS2CT52R240J in existing designs?

A: Yes. Both parts are electrically equivalent with identical resistance (24 Ohms), tolerance (±5%), and power rating (2W). Both utilize metal oxide film composition and axial through-hole packaging. Physical dimensions differ, but both conform to standard axial resistor form factors. PCB layout must accommodate the larger body dimensions of the RSF200JB-73-24R (5.00mm diameter vs. 4.00mm).

Q: What is the significance of the different operating temperature ranges?

A: The MOS2CT52R240J operates from -55°C to 200°C, while the RSF200JB-73-24R extends to 235°C. For applications operating within the -55°C to 200°C window, both parts perform identically. Applications requiring sustained operation above 200°C must use the RSF200JB-73-24R.

Q: Are there compliance differences between these parts?

A: No. Both parts are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 for export control purposes. Both share the identical HTSUS code (8533.21.0090), ensuring equivalent regulatory treatment.

Q: How do packaging formats affect part selection?

A: The MOS2CT52R240J is supplied in Cut Tape (CT) packaging, while the RSF200JB-73-24R is supplied in Bulk packaging. Cut Tape format is suitable for automated pick-and-place assembly, while Bulk format requires manual handling or reel conversion. Selection depends on manufacturing process requirements and inventory management practices.

Q: Is temperature coefficient a factor in substitution decisions?

A: The MOS2CT52R240J specifies a temperature coefficient of ±300ppm/°C. The RSF200JB-73-24R does not provide a temperature coefficient specification in the available data. For applications with strict temperature stability requirements, the specified temperature coefficient of the MOS2CT52R240J may be a determining factor.

Q: What physical space considerations apply when substituting these parts?

A: The RSF200JB-73-24R has larger axial dimensions (5.00mm diameter x 15.50mm length) compared to the MOS2CT52R240J (4.00mm diameter x 12.00mm length). PCB layouts must be verified to accommodate the larger body. Both parts maintain standard axial through-hole lead spacing compatible with 0.4-inch (10.16mm) pitch hole patterns.
