Substitute Part Grouping Explanation

Substitute parts for the RC5025F39R2CS are identified based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

Critical Matching Parameters:

• Resistance value: 39.2 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Package / Case: 2010 (5025 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 155°C (exact match required)
• Number of Terminations: 2 (exact match required)

Allowable Variation Parameters:

• Power Rating: Substitute parts may have equal or higher power ratings while maintaining identical physical dimensions and electrical characteristics
• Features: Substitute parts may include additional certifications or features (such as Automotive AEC-Q200) without affecting base functionality

The CRCW201039R2FKEF from Vishay Dale meets all critical matching parameters and represents a valid substitute with an increased power rating of 0.75W (3/4W) and additional Automotive AEC-Q200 certification.

Parameter Comparison

Engineering Selection Recommendations

Both the RC5025F39R2CS and CRCW201039R2FKEF are Active product status components with full regulatory compliance. Selection between these parts is determined by application-specific requirements:

RC5025F39R2CS Selection Criteria:

• Applications requiring standard moisture-resistant thick film construction
• Designs with power budget constraints at 0.667W (2/3W) rating
• Non-automotive applications where AEC-Q200 certification is not required
• Designs where the 0.026" (0.66mm) maximum seated height is a constraint

CRCW201039R2FKEF Selection Criteria:

• Automotive applications requiring AEC-Q200 qualification
• Designs benefiting from higher power rating margin at 0.75W (3/4W)
• Applications where additional automotive-grade reliability is specified
• Designs tolerating the 0.028" (0.70mm) maximum seated height

Both parts maintain identical electrical performance (39.2 Ohms ±1%, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range) and physical footprint compatibility in the 2010 (5025 Metric) package. The CRCW201039R2FKEF provides higher power dissipation capability and automotive certification without compromising form factor or electrical characteristics.

Frequently Asked Questions (FAQ)

Q: Can CRCW201039R2FKEF directly replace RC5025F39R2CS in existing designs?

A: Yes. Both parts share identical resistance (39.2 Ohms), tolerance (±1%), package (2010/5025 Metric), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The CRCW201039R2FKEF has a higher power rating (0.75W vs 0.667W) and slightly greater seated height (0.028" vs 0.026"), which are compatible with standard PCB layouts.

Q: What is the significance of the power rating difference?

A: The CRCW201039R2FKEF's 0.75W rating provides additional thermal margin compared to the RC5025F39R2CS's 0.667W rating. This allows the substitute part to dissipate more power without exceeding temperature limits. In applications operating at or near the original part's power rating, the substitute offers improved reliability through thermal headroom.

Q: Are there packaging differences between these parts?

A: The RC5025F39R2CS is supplied in standard packaging, while the CRCW201039R2FKEF is supplied in Tape & Reel (TR) format. Both use identical 2010 (5025 Metric) component packages with compatible PCB footprints. Tape & Reel packaging is standard for high-volume automated assembly.

Q: What does AEC-Q200 certification mean for the CRCW201039R2FKEF?

A: AEC-Q200 is an automotive industry qualification standard for passive components. The CRCW201039R2FKEF meets this specification, making it suitable for automotive applications. The RC5025F39R2CS does not carry this certification and should not be used in designs requiring automotive-grade components.

Q: Are both parts RoHS3 compliant?

A: Yes. Both RC5025F39R2CS and CRCW201039R2FKEF are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is Moisture Sensitivity Level 1?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. Both parts carry this rating, eliminating moisture-related storage constraints.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both parts operate across the identical temperature range of -55°C to 155°C with matching temperature coefficients of ±100ppm/°C, ensuring equivalent performance in thermal extremes.
