Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MOS2CT52R150J are classified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Electrical Parameters: Resistance value (15 Ohms), tolerance (±5%), and power rating (2W) must be identical. Composition (metal oxide film) and termination count (2) must match.

Mechanical Parameters: Package type (axial through-hole) and physical form factor must be compatible with the original design footprint.

Compliance Parameters: RoHS3 compliance and REACH unaffected status are maintained across all substitutes.

Substitutes are grouped into two categories:

Parametric Equivalent: MOS2CT52A150J maintains identical specifications across all electrical and mechanical parameters, with the same manufacturer (KOA Speer Electronics, Inc.) and series designation (MOS2CT52).

Similar Equivalent: RSF200JB-73-15R (YAGEO) provides electrical equivalence with identical resistance, tolerance, power rating, and composition. Physical dimensions differ slightly, and operating temperature range extends to 235°C. This substitute is suitable where mechanical envelope constraints permit dimensional variation.

Parameter Comparison

Engineering Selection Recommendations

MOS2CT52A150J is the primary substitute for MOS2CT52R150J. Both components are manufactured by KOA Speer Electronics, Inc., share identical electrical specifications, and maintain the same physical dimensions. This substitute provides direct interchangeability with no design modifications required. Both components are ROHS3 compliant and REACH unaffected, with active product status and equivalent inventory availability.

RSF200JB-73-15R (YAGEO) serves as an alternative substitute when supply constraints or cost considerations apply. Electrical specifications remain equivalent across resistance, tolerance, and power rating. The extended operating temperature range (-55°C to 235°C) provides additional thermal margin compared to the original component. Physical dimensions are larger (0.197" diameter x 0.610" length versus 0.157" diameter x 0.472" length), requiring verification of mechanical fit within the target application. This substitute maintains ROHS3 compliance and REACH unaffected status. Temperature coefficient data is not specified for this component.

Selection between substitutes depends on mechanical envelope constraints and thermal operating requirements of the specific application.

Frequently Asked Questions (FAQ)

Q: Can MOS2CT52A150J be used as a direct replacement for MOS2CT52R150J?

A: Yes. MOS2CT52A150J is a parametric equivalent with identical electrical specifications (15 Ohms, ±5%, 2W), composition (metal oxide film), and physical dimensions (0.157" Dia x 0.472" L). Both components are manufactured by KOA Speer Electronics, Inc., and maintain the same series designation (MOS2CT52). Direct substitution requires no design modifications.

Q: What are the physical dimension differences between MOS2CT52R150J and RSF200JB-73-15R?

A: MOS2CT52R150J measures 0.157" diameter x 0.472" length (4.00mm x 12.00mm). RSF200JB-73-15R measures 0.197" diameter x 0.610" length (5.00mm x 15.50mm). The YAGEO component is larger in both diameter and length. Mechanical fit verification is required before substitution in space-constrained applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. MOS2CT52A150J and RSF200JB-73-15R are both ROHS3 compliant and REACH unaffected, matching the compliance status of the original MOS2CT52R150J component.

Q: What is the temperature coefficient difference between the main part and RSF200JB-73-15R?

A: MOS2CT52R150J specifies a temperature coefficient of ±300ppm/°C. RSF200JB-73-15R does not provide temperature coefficient data in the available specifications. Operating temperature range for RSF200JB-73-15R extends to 235°C, compared to 200°C for MOS2CT52R150J.

Q: Can RSF200JB-73-15R be used in applications requiring the full -55°C to 200°C operating range?

A: Yes. RSF200JB-73-15R operates across -55°C to 235°C, which encompasses the -55°C to 200°C range of MOS2CT52R150J. The extended upper temperature limit provides additional thermal margin. Physical dimension differences must be verified for mechanical compatibility.

Q: Are there packaging differences between the substitute parts?

A: MOS2CT52R150J and MOS2CT52A150J are supplied in Cut Tape (CT) packaging. RSF200JB-73-15R is supplied in Bulk packaging. This distinction affects handling and storage procedures but does not impact electrical or mechanical performance.
