Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MOS2CT52R302J is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 3 kOhms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Metal Oxide Film

Mechanical Compatibility Requirements:

• Package configuration: Axial through-hole
• Number of terminations: 2
• Physical mounting compatibility with axial lead spacing

Regulatory and Compliance Requirements:

• RoHS3 compliance status
• REACH unaffected designation
• ECCN and HTSUS classification alignment

Substitute parts meeting all electrical, mechanical, and regulatory criteria are classified as direct equivalents suitable for circuit board assembly and replacement applications.

Parameter Comparison

Engineering Selection Recommendations

Both the MOS2CT52R302J and RSF200JB-73-3K meet the core electrical and mechanical requirements for direct substitution. Selection between these components is based on the following engineering considerations:

MOS2CT52R302J (KOA Speer Electronics):

• Specified operating temperature range: -55°C to 200°C
• Temperature coefficient: ±300ppm/°C (specified)
• Flame retardant coating designation
• Packaging: Cut Tape format
• Active product status with full regulatory compliance

RSF200JB-73-3K (YAGEO):

• Extended operating temperature range: -55°C to 235°C
• Temperature coefficient: Not specified in available data
• Flame proof designation
• Packaging: Bulk format
• Active product status with full regulatory compliance
• Moisture sensitivity level: 1 (Unlimited)

Both components maintain RoHS3 compliance, REACH unaffected status, and identical ECCN/HTSUS classifications. The RSF200JB-73-3K provides extended upper temperature capability, while the MOS2CT52R302J specifies temperature coefficient performance. Component selection depends on application-specific temperature requirements and packaging format availability.

Frequently Asked Questions (FAQ)

Q: Can RSF200JB-73-3K replace MOS2CT52R302J in all applications?

A: The RSF200JB-73-3K meets all core electrical specifications (3 kOhms, ±5%, 2W, metal oxide film) and mechanical requirements (axial, 2 terminations). The extended operating temperature range (-55°C to 235°C versus -55°C to 200°C) provides additional thermal capability. Substitution is valid for applications operating within the MOS2CT52R302J temperature range. Applications requiring operation above 200°C benefit from the RSF200JB-73-3K extended range.

Q: What are the physical dimension differences between these parts?

A: MOS2CT52R302J dimensions are 0.157" diameter × 0.472" length (4.00mm × 12.00mm). RSF200JB-73-3K dimensions are 0.197" diameter × 0.610" length (5.00mm × 15.50mm). The RSF200JB-73-3K is physically larger. Board layout and component spacing must accommodate the larger axial package dimensions.

Q: Are packaging format differences significant for substitution?

A: MOS2CT52R302J is supplied in Cut Tape packaging; RSF200JB-73-3K is supplied in Bulk packaging. Both formats contain identical components. Packaging format affects procurement and handling procedures but does not impact electrical or mechanical performance in the final assembly.

Q: Do both parts meet current regulatory requirements?

A: Both MOS2CT52R302J and RSF200JB-73-3K are RoHS3 compliant and REACH unaffected. Both carry identical ECCN (EAR99) and HTSUS (8533.21.0090) classifications. Both components satisfy current regulatory requirements for electronic component applications.

Q: What is the significance of the temperature coefficient specification?

A: The MOS2CT52R302J specifies ±300ppm/°C temperature coefficient. The RSF200JB-73-3K temperature coefficient is not specified in available data. Temperature coefficient defines resistance value drift across the operating temperature range. Applications requiring predictable resistance stability across temperature variations should reference the specified ±300ppm/°C value for the MOS2CT52R302J.

Q: Can these parts be used interchangeably on existing circuit boards?

A: Electrical interchangeability is confirmed. Mechanical interchangeability requires verification of board layout clearances. The RSF200JB-73-3K larger physical dimensions (0.197" × 0.610" versus 0.157" × 0.472") may require spacing validation on existing board designs. New designs should accommodate the larger package dimensions if RSF200JB-73-3K substitution is planned.
