Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MOS2CT52R103J is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 10 kOhms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Metal Oxide Film
• Package type: Axial
• Number of terminations: 2
• RoHS compliance: ROHS3 Compliant

Acceptable Variation Parameters:

• Operating temperature range: Substitute may exceed the minimum specification
• Physical dimensions: Minor variations permitted within axial package constraints
• Packaging format: Cut Tape or Bulk acceptable
• Flame protection features: Flame Retardant or Flame Proof both acceptable
• Temperature coefficient: Specification provided for reference; substitute value of "-" (not specified) does not disqualify

Substitute parts are grouped into two categories: Parametric Equivalent (identical specifications from same manufacturer) and Similar Manufacturer (equivalent specifications from alternative manufacturer with acceptable dimensional and thermal variations).

Parameter Comparison

Engineering Selection Recommendations

MOS2CVTPA103J (KOA Speer Electronics, Inc.) - Parametric Equivalent

The MOS2CVTPA103J is a direct parametric equivalent to the MOS2CT52R103J. Both parts are manufactured by KOA Speer Electronics, Inc., share identical electrical specifications (10 kOhms ±5% 2W), identical physical dimensions (4.00mm x 12.00mm), and identical operating temperature range (-55°C ~ 200°C). Both are ROHS3 Compliant and REACH Unaffected. The primary distinction is the flame protection feature: MOS2CVTPA103J provides Flame Proof protection compared to Flame Retardant Coating on the MOS2CT52R103J. Both are Active products. This substitute offers higher inventory availability (1772 units versus 814 units).

RSF200JB-73-10K (YAGEO) - Similar Manufacturer Equivalent

The RSF200JB-73-10K is a similar manufacturer equivalent produced by YAGEO. Electrical specifications are identical to the MOS2CT52R103J (10 kOhms ±5% 2W metal oxide film composition). Physical dimensions differ: RSF200JB-73-10K measures 5.00mm x 15.50mm compared to 4.00mm x 12.00mm for the MOS2CT52R103J. Operating temperature range extends to -55°C ~ 235°C, exceeding the MOS2CT52R103J specification. Both are ROHS3 Compliant and REACH Unaffected. The RSF200JB-73-10K is supplied in Bulk packaging format and offers significantly higher inventory availability (15721 units). Temperature coefficient specification is not provided for the YAGEO part. This substitute is suitable for applications where the larger physical footprint is acceptable and extended temperature performance is beneficial.

Frequently Asked Questions (FAQ)

Q: Can MOS2CVTPA103J be used as a direct replacement for MOS2CT52R103J?

A: Yes. The MOS2CVTPA103J meets all mandatory electrical and mechanical parameters: 10 kOhms resistance, ±5% tolerance, 2W power rating, metal oxide film composition, axial package, and identical physical dimensions (4.00mm x 12.00mm). Both operate across -55°C ~ 200°C and are ROHS3 Compliant. The flame protection feature upgrade (Flame Proof versus Flame Retardant) does not disqualify substitution.

Q: What are the physical dimension differences between MOS2CT52R103J and RSF200JB-73-10K?

A: MOS2CT52R103J measures 0.157" diameter x 0.472" length (4.00mm x 12.00mm). RSF200JB-73-10K measures 0.197" diameter x 0.610" length (5.00mm x 15.50mm). The YAGEO part is larger in both diameter and length. PCB layout and mechanical clearance must accommodate the larger footprint.

Q: Does the extended operating temperature range of RSF200JB-73-10K affect substitution suitability?

A: No. The RSF200JB-73-10K operating range of -55°C ~ 235°C exceeds the MOS2CT52R103J specification of -55°C ~ 200°C. Extended temperature capability does not compromise substitution eligibility for applications operating within the original specification range.

Q: Are all three parts RoHS compliant?

A: Yes. MOS2CT52R103J, MOS2CVTPA103J, and RSF200JB-73-10K are all ROHS3 Compliant and REACH Unaffected.

Q: What is the difference between Flame Retardant Coating and Flame Proof features?

A: MOS2CT52R103J features Flame Retardant Coating. MOS2CVTPA103J and RSF200JB-73-10K feature Flame Proof protection. Both designations indicate safety characteristics; Flame Proof represents an enhanced protection level. Both are acceptable for substitution purposes.

Q: Which substitute part offers better inventory availability?

A: RSF200JB-73-10K offers the highest inventory availability with 15721 units in stock, compared to 1772 units for MOS2CVTPA103J and 814 units for MOS2CT52R103J. However, inventory levels are subject to change and should be confirmed at time of procurement.

Q: Can RSF200JB-73-10K be used in space-constrained applications?

A: RSF200JB-73-10K is larger than MOS2CT52R103J (5.00mm x 15.50mm versus 4.00mm x 12.00mm). Applications with strict PCB layout constraints or limited component clearance may require the smaller MOS2CT52R103J or MOS2CVTPA103J.

Q: Is temperature coefficient specification critical for substitution?

A: MOS2CT52R103J and MOS2CVTPA103J both specify ±300ppm/°C temperature coefficient. RSF200JB-73-10K does not provide this specification. For applications requiring precise temperature coefficient matching, MOS2CVTPA103J is the preferred equivalent. For general applications, the absence of specification on RSF200JB-73-10K does not disqualify substitution.
