Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MOS2CT52R472J is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 4.7 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 2W (exact match required)
• Composition: Metal Oxide Film (exact match required)

Mechanical Equivalence Requirements:

• Package configuration: Axial through-hole (exact match required)
• Number of terminations: 2 (exact match required)

Compliance Requirements:

• RoHS3 Compliant status (mandatory for substitution)
• REACH Unaffected status (mandatory for substitution)

The RSF200JB-73-4K7 manufactured by YAGEO meets all electrical and mechanical equivalence criteria. Both parts share identical resistance, tolerance, power rating, and composition specifications. Both are packaged as 2-termination axial through-hole components and maintain ROHS3 and REACH compliance. Physical dimensions differ slightly, but both conform to standard axial resistor form factors suitable for PCB mounting in equivalent footprints.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The MOS2CT52R472J remains the preferred selection when available. This part is Active in product status with established supply inventory of 2939 pieces. KOA Speer Electronics maintains consistent manufacturing standards for this metal oxide film resistor series.

Substitute Part Selection: The RSF200JB-73-4K7 is a direct electrical and mechanical equivalent suitable for deployment when MOS2CT52R472J availability is constrained. Both parts satisfy ROHS3 and REACH compliance requirements. The YAGEO substitute demonstrates an extended operating temperature range (-55°C ~ 235°C versus -55°C ~ 200°C), providing additional thermal margin in applications approaching the upper temperature limit of the original specification.

Physical Dimension Consideration: The RSF200JB-73-4K7 exhibits larger physical dimensions (0.197" Dia x 0.610" L) compared to the MOS2CT52R472J (0.157" Dia x 0.472" L). PCB layout verification is required to confirm that the substitute component fits within allocated board space and does not create clearance conflicts with adjacent components or traces.

Frequently Asked Questions (FAQ)

Q: Can the RSF200JB-73-4K7 be used as a direct replacement for the MOS2CT52R472J?

A: Yes, the RSF200JB-73-4K7 is electrically and mechanically equivalent. Both parts are 4.7 kOhms ±5% 2W metal oxide film axial resistors with identical electrical specifications and compliance certifications. Physical dimensions differ, requiring verification that the substitute component accommodates existing PCB footprint space.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution is determined by exact equivalence in resistance value (4.7 kOhms), tolerance (±5%), power rating (2W), composition (metal oxide film), package type (axial), and compliance status (ROHS3 and REACH). Deviations in any of these parameters disqualify a component from substitution consideration.

Q: Does the RSF200JB-73-4K7 have a wider operating temperature range?

A: Yes. The RSF200JB-73-4K7 operates across -55°C ~ 235°C, compared to the MOS2CT52R472J range of -55°C ~ 200°C. This extended upper temperature limit provides additional thermal headroom for applications operating near the original part's maximum temperature specification.

Q: Are there packaging differences between these parts?

A: The MOS2CT52R472J is supplied in Cut Tape (CT) packaging, while the RSF200JB-73-4K7 is supplied in Bulk packaging. This distinction affects procurement and handling procedures but does not impact electrical or mechanical performance of the individual components.

Q: What physical dimension differences exist between these resistors?

A: The MOS2CT52R472J measures 0.157" diameter by 0.472" length (4.00mm x 12.00mm). The RSF200JB-73-4K7 measures 0.197" diameter by 0.610" length (5.00mm x 15.50mm). Both are standard axial form factors, but the substitute is physically larger. PCB layout confirmation is necessary before substitution.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the MOS2CT52R472J and RSF200JB-73-4K7 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic component procurement.
