MOS2CT52R242J Equivalent & Substitute Parts

Part Overview

The MOS2CT52R242J is a 2.4 kOhms ±5% 2W through-hole resistor manufactured by KOA Speer Electronics, Inc. This metal oxide film axial 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 2082 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.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MOS2CT52R242J is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 2.4 kOhms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Metal Oxide Film

Mechanical Compatibility Requirements:

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

Compliance Requirements:

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

The substitute part RSF200JB-73-2K4 meets all electrical and mechanical equivalence criteria. Physical dimensions and temperature coefficient variations do not preclude substitution when the primary electrical and mechanical specifications align.

Parameter Comparison

Engineering Selection Recommendations

Both the MOS2CT52R242J and RSF200JB-73-2K4 maintain Active product status with full RoHS3 and REACH compliance. Selection between these parts is based on availability and procurement requirements rather than functional performance differences.

The MOS2CT52R242J (KOA Speer) provides specified temperature coefficient data (±300ppm/°C) and operates within -55°C to 200°C. The RSF200JB-73-2K4 (YAGEO) extends the upper operating temperature to 235°C, offering broader thermal capability for high-temperature applications. Both parts are manufactured to identical electrical specifications and axial package configuration.

Current inventory levels show 4437 units of the YAGEO substitute against 2082 units of the primary part, indicating relative availability in the supply chain. Selection should be based on application thermal requirements and procurement lead time considerations.

Frequently Asked Questions (FAQ)

Q: Can RSF200JB-73-2K4 be used as a direct replacement for MOS2CT52R242J?

A: Yes. Both parts share identical resistance (2.4 kOhms), tolerance (±5%), power rating (2W), composition (metal oxide film), and axial package configuration. Electrical and mechanical compatibility is complete.

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

A: The MOS2CT52R242J measures 0.157" diameter × 0.472" length (4.00mm × 12.00mm). The RSF200JB-73-2K4 measures 0.197" diameter × 0.610" length (5.00mm × 15.50mm). Both are axial through-hole components; physical size variation requires PCB layout verification.

Q: Are there compliance differences between the two parts?

A: No. Both parts are ROHS3 Compliant, REACH Unaffected, classified as ECCN EAR99, and share the same HTSUS code (8533.21.0090).

Q: What is the temperature coefficient difference?

A: The MOS2CT52R242J specifies ±300ppm/°C. Temperature coefficient data is not provided for the RSF200JB-73-2K4. For applications requiring precise temperature coefficient specifications, the KOA Speer part provides documented performance data.

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

A: The RSF200JB-73-2K4 operates to 235°C maximum, compared to 200°C for the MOS2CT52R242J. For applications approaching or exceeding 200°C, the YAGEO substitute provides extended thermal capability.

Q: Are packaging differences significant for PCB assembly?

A: The MOS2CT52R242J is supplied in Cut Tape packaging, while RSF200JB-73-2K4 is supplied in Bulk packaging. Assembly process compatibility should be verified with manufacturing specifications. Physical dimension differences also require PCB footprint confirmation.
