Key Parameters

Substitute Part Grouping Explanation

Substitution of the MOS2CT52R751J is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 750 Ohms (exact match required)
• Tolerance: ±5% (identical tolerance band)
• Power rating: 2W (minimum requirement)
• Composition: Metal Oxide Film (same technology)

Mechanical Equivalence Requirements:

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

Compliance Requirements:

• RoHS3 Compliant status
• REACH Unaffected designation
• ECCN classification: EAR99

The RSF200JB-73-750R from YAGEO meets all electrical and mechanical substitution criteria. Both components share identical resistance, tolerance, power rating, and composition specifications. Both are configured as 2-terminal axial through-hole resistors suitable for identical circuit board layouts and soldering processes.

The YAGEO substitute provides superior thermal operating range, making it suitable for applications requiring extended high-temperature performance within the specified limits.

Frequently Asked Questions (FAQ)

Q: Can RSF200JB-73-750R replace MOS2CT52R751J in existing circuit designs?

A: Yes. Both components share identical electrical specifications (750 Ohms, ±5%, 2W) and identical axial through-hole package configuration. Direct substitution is supported for circuit board layouts and soldering processes designed for the original component.

Q: Are there physical dimension differences between these components?

A: Yes. The MOS2CT52R751J measures 0.157" Dia x 0.472" L (4.00mm x 12.00mm). The RSF200JB-73-750R measures 0.197" Dia x 0.610" L (5.00mm x 15.50mm). The YAGEO substitute is physically larger. Circuit board layout must accommodate the larger dimensions, including lead spacing and component clearance requirements.

Q: Do both components meet the same regulatory standards?

A: Yes. Both the MOS2CT52R751J and RSF200JB-73-750R carry RoHS3 compliance and REACH unaffected designation. Both are classified as EAR99 for export control purposes.

Q: What is the temperature performance difference?

A: The MOS2CT52R751J operates across -55°C to 200°C. The RSF200JB-73-750R operates across -55°C to 235°C. The YAGEO component provides 35°C additional high-temperature operating margin.

Q: Are packaging formats different between these components?

A: Yes. The MOS2CT52R751J is supplied in Cut Tape (CT) packaging. The RSF200JB-73-750R is supplied in Bulk packaging. Procurement and handling processes differ accordingly.

Q: Can these components be used interchangeably in high-reliability applications?

A: Both components carry Active product status and full compliance certifications. Substitution is supported based on electrical and mechanical equivalence. Application-specific reliability requirements should be evaluated against manufacturer datasheets and qualification standards.
