Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MOS2CT52R513J is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 51 kOhms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Metal Oxide Film

Mechanical Equivalence Requirements:

• Package type: Axial through-hole configuration
• Number of terminations: 2
• Physical form factor: Axial lead resistor

Compliance Requirements:

• RoHS3 Compliant status
• REACH Unaffected status
• ECCN: EAR99 classification
• HTSUS: 8533.21.0090 tariff code

The RSF200JB-73-51K from YAGEO meets all electrical and mechanical equivalence criteria, with identical resistance, tolerance, power rating, and composition specifications. Both parts are RoHS3 compliant and share the same regulatory classification.

Parameter Comparison

Engineering Selection Recommendations

Both the MOS2CT52R513J and RSF200JB-73-51K are Active product status components with full RoHS3 compliance and REACH Unaffected regulatory standing. Selection between these parts is based on application-specific requirements and procurement constraints.

MOS2CT52R513J Selection Criteria:

• Applications requiring confirmed temperature coefficient specification of ±300ppm/°C
• Operating environments limited to -55°C ~ 200°C maximum temperature
• Cut Tape packaging preference for automated assembly processes
• KOA Speer manufacturer preference or qualification requirements

RSF200JB-73-51K Selection Criteria:

• Applications benefiting from extended upper operating temperature limit of 235°C
• Bulk packaging compatibility with manual assembly or alternative handling processes
• YAGEO manufacturer preference or qualification requirements
• Higher inventory availability (4964 units in stock)

Both parts satisfy identical electrical specifications, mechanical form factors, and regulatory compliance requirements. The RSF200JB-73-51K provides extended temperature capability, while the MOS2CT52R513J offers documented temperature coefficient performance.

Frequently Asked Questions (FAQ)

Q: Can the RSF200JB-73-51K directly replace the MOS2CT52R513J in existing designs?

A: Yes. Both parts share identical resistance value (51 kOhms), tolerance (±5%), power rating (2W), composition (Metal Oxide Film), and axial package configuration. Electrical and mechanical compatibility is confirmed across all specified parameters.

Q: What is the primary difference between these two parts?

A: The RSF200JB-73-51K operates across an extended temperature range (-55°C ~ 235°C) compared to the MOS2CT52R513J (-55°C ~ 200°C). The MOS2CT52R513J provides a specified temperature coefficient of ±300ppm/°C, while the RSF200JB-73-51K temperature coefficient is not specified in available documentation. Physical dimensions differ slightly: MOS2CT52R513J measures 0.157" Dia x 0.472" L, while RSF200JB-73-51K measures 0.197" Dia x 0.610" L.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the MOS2CT52R513J and RSF200JB-73-51K carry RoHS3 Compliant certification and REACH Unaffected status, meeting current environmental and regulatory requirements.

Q: What packaging formats are available for each part?

A: The MOS2CT52R513J is supplied in Cut Tape (CT) packaging format. The RSF200JB-73-51K is supplied in Bulk packaging format. Packaging selection depends on assembly process requirements and handling procedures.

Q: Which part should be selected for high-temperature applications?
