Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following parameters: resistance value (130 Ohms), tolerance (±5%), power rating (2W), composition (metal oxide film), and axial package configuration. All substitute parts must maintain these core electrical and mechanical specifications to ensure functional compatibility.

The MOS2CT52A131J has two identified substitutes:

Parametric Equivalent (MOS2CT52R131J): Identical resistance, tolerance, power rating, composition, and package type. Differs only in flame-retardant coating feature (flame retardant coating versus flame proof) and maintains the same operating temperature range and temperature coefficient.

Similar Equivalent (RSF200JB-73-130R): Matches resistance, tolerance, power rating, composition, and axial package configuration. Physical dimensions differ (0.197" Dia x 0.610" L versus 0.157" Dia x 0.472" L), and operating temperature range extends to 235°C. Temperature coefficient specification is not provided for this part.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status and full compliance with ROHS3 and REACH regulations. Selection between MOS2CT52A131J and MOS2CT52R131J should be based on packaging availability and specific flame-retardant requirements, as both parts are electrically and mechanically identical with matching temperature coefficients and operating ranges.

Selection of RSF200JB-73-130R requires consideration of physical dimensions, as this part is larger (0.197" Dia x 0.610" L) compared to the original specification (0.157" Dia x 0.472" L). This part extends the operating temperature range to 235°C but does not specify a temperature coefficient value. PCB layout and thermal design constraints must be evaluated before substitution.

Frequently Asked Questions (FAQ)

Q: Can MOS2CT52R131J be used as a direct replacement for MOS2CT52A131J?

A: Yes. Both parts share identical electrical specifications (130 Ohms ±5%, 2W, ±300ppm/°C) and physical dimensions (0.157" Dia x 0.472" L). The only difference is the flame-retardant coating feature. Both are ROHS3 compliant and active in production.

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

A: MOS2CT52A131J and MOS2CT52R131J are identical at 0.157" Dia x 0.472" L (4.00mm x 12.00mm). RSF200JB-73-130R is larger at 0.197" Dia x 0.610" L (5.00mm x 15.50mm), which may affect PCB layout compatibility.

Q: Is RSF200JB-73-130R suitable for applications requiring the original operating temperature range?

A: RSF200JB-73-130R operates from -55°C to 235°C, which exceeds the original specification of -55°C to 200°C. It is suitable for applications within the original range. However, the temperature coefficient is not specified for this part, which may be a consideration for precision applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. MOS2CT52A131J, MOS2CT52R131J, and RSF200JB-73-130R are all ROHS3 compliant and REACH unaffected.

Q: What packaging formats are available for these parts?

A: MOS2CT52A131J and MOS2CT52R131J are supplied in Cut Tape (CT) packaging. RSF200JB-73-130R is supplied in Bulk packaging. Packaging selection depends on assembly process requirements and inventory management preferences.
