MOS2CT52R153J Equivalent & Substitute Parts

Part Overview

The MOS2CT52R153J is a 15 kOhms ±5% 2W through-hole resistor manufactured by KOA Speer Electronics, Inc. This axial metal oxide film resistor features flame retardant coating and safety construction, designed for applications requiring reliable performance across industrial temperature ranges. The part maintains Active product status with 1492 units in current inventory stock.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same component category. Substitution becomes necessary due to supply chain availability, inventory levels, or procurement preferences while maintaining identical functional performance.

Substitute Part Grouping Explanation

Substitution eligibility for the MOS2CT52R153J is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 15 kOhms (exact match)
• Tolerance: ±5% (exact match)
• Power rating: 2W (exact match)
• Composition: Metal Oxide Film (exact match)

Mechanical Compatibility Requirements:

• Package type: Axial (exact match)
• Number of terminations: 2 (exact match)
• Through-hole configuration (exact match)

Compliance Requirements:

• RoHS3 Compliant status (exact match)
• REACH Unaffected status (exact match)

The substitute part RSF200JB-73-15K meets all electrical and mechanical equivalence criteria. Physical dimensions and temperature coefficient variations do not affect functional substitution within the specified operating parameters.

Engineering Selection Recommendations

MOS2CT52R153J Selection Criteria:

• Primary choice when Cut Tape packaging is required for automated assembly processes
• Preferred when KOA Speer Electronics supply chain is established
• Suitable for applications operating within -55°C to 200°C range
• Current inventory availability: 1492 units

RSF200JB-73-15K Selection Criteria:

• Suitable alternative when bulk packaging accommodates procurement requirements
• Extended operating temperature capability to 235°C provides margin for high-temperature applications
• Higher inventory availability: 8591 units
• YAGEO manufacturer qualification required in design documentation

Both parts maintain identical electrical performance, RoHS3 compliance, and REACH unaffected status. Selection between these parts depends on packaging format requirements, supply chain preferences, and temperature margin specifications rather than functional performance differences.

Frequently Asked Questions (FAQ)

Q: Can RSF200JB-73-15K replace MOS2CT52R153J in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance (15 kOhms), tolerance (±5%), power rating (2W), composition (metal oxide film), and axial package configuration. Substitution is direct for applications operating within the MOS2CT52R153J temperature range of -55°C to 200°C.

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

A: The primary differences are packaging format (Cut Tape versus Bulk) and operating temperature upper limit (200°C versus 235°C). Electrical specifications and mechanical compatibility are identical.

Q: Does packaging format affect circuit performance?

A: No. Packaging format (Cut Tape or Bulk) affects procurement and assembly processes only. Circuit performance and electrical characteristics remain identical regardless of packaging format.

Q: Are both parts RoHS3 compliant?

A: Yes. Both MOS2CT52R153J and RSF200JB-73-15K are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: Can I use RSF200JB-73-15K in applications exceeding 200°C?

A: RSF200JB-73-15K is rated to 235°C maximum operating temperature, providing additional thermal margin. However, application-specific thermal analysis is required to confirm suitability for temperatures above 200°C.

Q: What does the ±5% tolerance specification mean?

A: The ±5% tolerance indicates that the actual resistance value will fall within 14.25 kOhms to 15.75 kOhms. Both substitute parts maintain this identical tolerance specification.

Q: Are the physical dimensions identical?

A: Physical dimensions differ slightly. MOS2CT52R153J measures 0.157" Dia x 0.472" L (4.00mm x 12.00mm), while RSF200JB-73-15K measures 0.197" Dia x 0.610" L (5.00mm x 15.50mm). Both fit standard axial component footprints with appropriate lead spacing.
