Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC5025F3652CS are qualified based on the following criteria:

Electrical Parameters (Critical for Substitution):

• Resistance value: 36.5 kOhms
• Tolerance: ±1%
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Critical for Substitution):

• Package type: 2010 (5025 Metric)
• Physical dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm)
• Composition: Thick Film
• Number of terminations: 2

Compliance Parameters:

• RoHS3 Compliant
• Moisture Sensitivity Level 1 (Unlimited)

Power Rating Consideration: Substitute parts may have equal or higher power ratings (0.75W or greater) while maintaining all other electrical and mechanical specifications. Higher power ratings do not affect circuit functionality and provide additional thermal margin.

Engineering Selection Recommendations

Primary Substitute: CRCW201036K5FKEF (Vishay Dale)

The CRCW201036K5FKEF is the recommended substitute for new designs and production applications. This part maintains all critical electrical and mechanical parameters identical to the RC5025F3652CS while offering an increased power rating of 0.75W. The component carries Active product status, ensuring continued availability and manufacturing support. CRCW201036K5FKEF includes AEC-Q200 automotive qualification, providing additional reliability assurance for demanding applications. RoHS3 compliance and MSL 1 rating match the original specification.

Secondary Substitute: ERJ-12SF3652U (Panasonic Electronic Components)

The ERJ-12SF3652U provides electrical and mechanical equivalence to the RC5025F3652CS with identical resistance, tolerance, temperature coefficient, and package specifications. This part carries AEC-Q200 automotive qualification and RoHS3 compliance. However, ERJ-12SF3652U is designated as Not For New Designs, indicating that Panasonic has discontinued active development for this product line. This part remains suitable for legacy system maintenance and repair applications where existing inventory is available, but should not be selected for new circuit designs or long-term production commitments.

Frequently Asked Questions (FAQ)

Q: Can CRCW201036K5FKEF replace RC5025F3652CS in existing circuits?

A: Yes. The CRCW201036K5FKEF is a direct functional equivalent. Both parts share identical resistance value (36.5 kOhms), tolerance (±1%), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and 2010 package dimensions. The higher power rating (0.75W vs. 0.667W) does not affect circuit operation and provides additional thermal headroom.

Q: What is the difference between the 2/3W and 3/4W power ratings?

A: The power rating indicates the maximum continuous power dissipation the resistor can handle without exceeding temperature limits. A 0.75W (3/4W) rated resistor can safely dissipate more power than a 0.667W (2/3W) rated resistor. In circuit applications where power dissipation does not exceed 0.667W, both ratings are functionally equivalent. Higher-rated parts provide design margin and thermal stability.

Q: Why is ERJ-12SF3652U marked as "Not For New Designs"?

A: This designation indicates that Panasonic has transitioned this product to end-of-life status and is not actively developing or promoting it for new applications. While existing inventory may be available, long-term supply cannot be guaranteed. For new circuit designs and production programs, CRCW201036K5FKEF (Active status) is the recommended choice.

Q: Are all three parts mechanically interchangeable?

A: Yes. RC5025F3652CS, CRCW201036K5FKEF, and ERJ-12SF3652U all use the 2010 (5025 Metric) package with identical physical dimensions (0.197" L x 0.098" W / 5.00mm x 2.50mm). They are mechanically interchangeable in PCB layouts and automated assembly processes.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. RC5025F3652CS, CRCW201036K5FKEF, and ERJ-12SF3652U are all ROHS3 Compliant. All parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: What is the significance of AEC-Q200 qualification on the substitute parts?

A: AEC-Q200 is an automotive industry qualification standard that certifies component reliability under automotive operating conditions. Both CRCW201036K5FKEF and ERJ-12SF3652U carry this qualification, indicating they meet stringent automotive reliability requirements. This qualification is not a requirement for general industrial applications but provides additional assurance of component quality and consistency.
