Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC5025F64R9CS are qualified based on the following criteria:

Electrical Parameters (Critical):

• Resistance value: 64.9 Ohms
• Tolerance: ±1%
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C

Mechanical Parameters (Critical):

• Package / Case: 2010 (5025 Metric)
• Composition: Thick Film
• Number of Terminations: 2

Compliance Parameters:

• RoHS3 Compliance
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts identified in this reference maintain identical resistance, tolerance, temperature coefficient, and operating temperature specifications. All substitute parts are packaged in the 2010 (5025 Metric) form factor with two terminations, ensuring mechanical and electrical interchangeability. Power rating variations (0.75W vs. 0.667W) represent uprated alternatives suitable for applications requiring higher power dissipation margins within the same package envelope.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status): The RC5025F64R9CS remains the specified component for new designs. CRCW201064R9FKEF (Vishay Dale) and RMCF2010FT64R9 (Stackpole Electronics Inc) are both Active status alternatives with identical electrical parameters and higher power ratings (0.75W), providing enhanced thermal margin within the same 2010 package footprint.

Secondary Selection (Legacy Applications): ERJ-12SF64R9U (Panasonic Electronic Components) is classified as Not For New Designs and should be used only for replacement or maintenance of existing assemblies where component continuity is required.

Compliance Considerations: All identified substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring regulatory and environmental compatibility with the original specification.

Power Rating Upgrade Path: Substitute parts rated at 0.75W (3/4W) provide 12.5% additional power dissipation capacity compared to the 0.667W (2/3W) original specification, while maintaining identical electrical characteristics and mechanical footprint. This uprating is suitable for applications requiring improved thermal performance without PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can CRCW201064R9FKEF replace RC5025F64R9CS in existing designs? A: Yes. CRCW201064R9FKEF maintains identical resistance (64.9 Ohms), tolerance (±1%), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). The 2010 (5025 Metric) package dimensions and two-terminal configuration ensure mechanical and electrical compatibility. The higher power rating (0.75W vs. 0.667W) represents an uprated alternative suitable for the same application space.

Q: What is the difference between the 0.667W and 0.75W power ratings? A: Both ratings apply to the same 2010 (5025 Metric) package envelope. The 0.75W rating provides 12.5% additional power dissipation capacity. Selection between these ratings depends on circuit power requirements; the 0.75W alternatives offer thermal margin for applications approaching the original 0.667W specification limit.

Q: Are all substitute parts suitable for automotive applications? A: CRCW201064R9FKEF, ERJ-12SF64R9U, and RMCF2010FT64R9 are all rated for Automotive AEC-Q200 compliance. The original RC5025F64R9CS does not specify AEC-Q200 rating. For automotive applications requiring AEC-Q200 qualification, substitute parts provide this additional certification.

Q: Why is ERJ-12SF64R9U marked as Not For New Designs? A: ERJ-12SF64R9U carries a Not For New Designs product status designation from Panasonic Electronic Components. This part remains available for replacement and maintenance of existing assemblies but should not be selected for new product development. Use CRCW201064R9FKEF or RMCF2010FT64R9 for new designs.

Q: Are there height differences between the main part and substitutes? A: Yes. RC5025F64R9CS has a maximum seated height of 0.026" (0.66mm), while substitute parts CRCW201064R9FKEF, ERJ-12SF64R9U, and RMCF2010FT64R9 have a maximum seated height of 0.028" (0.70mm). This 0.002" (0.04mm) difference is within typical PCB assembly tolerances and does not affect interchangeability for standard applications. Verify clearance for height-constrained designs.

Q: Do all parts have the same moisture sensitivity rating? A: Yes. RC5025F64R9CS and all substitute parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.

Q: Which substitute part offers the best long-term availability? A: CRCW201064R9FKEF (Vishay Dale) and RMCF2010FT64R9 (Stackpole Electronics Inc) both carry Active product status, indicating ongoing manufacturing and supply. ERJ-12SF64R9U is Not For New Designs and should not be relied upon for new product commitments.
