Substitute Part Grouping Explanation

Substitute parts for the RC5025F73R2CS are qualified based on strict electrical and mechanical parameter matching. All substitute candidates must satisfy the following criteria:

Mandatory Matching Parameters:

• Resistance value: 73.2 Ohms
• Tolerance: ±1%
• Package format: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

• RoHS3 compliance: Required
• MSL rating: 1 (Unlimited)

Power Rating Consideration: Substitute parts rated at 0.75W (3/4W) or higher are functionally equivalent to the 0.667W (2/3W) main part, as higher power ratings provide equal or superior thermal performance in the same package footprint. Parts with lower power ratings are excluded.

Identified Substitute Categories:

Upgrade Substitutes (Higher Power Rating):

• RC2010FK-0773R2L (YAGEO) – 0.75W rating

Similar Substitutes (Higher Power Rating with Additional Certifications):

• CRCW201073R2FKEF (Vishay Dale) – 0.75W rating, AEC-Q200 automotive qualification
• RMCF2010FT73R2 (Stackpole Electronics Inc) – 0.75W rating, AEC-Q200 automotive qualification

Parameter Comparison

Engineering Selection Recommendations

RC2010FK-0773R2L (YAGEO RC_L Series)

This part qualifies as a direct upgrade substitute. It maintains identical electrical specifications (73.2 Ohms ±1%, ±100ppm/°C, -55°C to 155°C) and package format (2010 metric) while providing increased power dissipation capacity (0.75W versus 0.667W). The higher power rating offers improved thermal margin in the same footprint. RoHS3 compliance and MSL 1 rating match the main part. Tape & Reel packaging supports automated assembly processes. This substitute is suitable for general industrial applications where automotive qualification is not required.

CRCW201073R2FKEF (Vishay Dale CRCW Series)

This part meets all electrical and mechanical requirements with identical resistance, tolerance, temperature coefficient, and operating range. The 0.75W power rating provides thermal performance equivalent to or exceeding the main part. This component carries AEC-Q200 automotive qualification, indicating compliance with automotive reliability and environmental stress testing standards. RoHS3 and MSL 1 compliance are maintained. Height specification (0.028" maximum) is slightly elevated compared to the main part but remains within typical PCB design tolerances. This substitute is appropriate for automotive applications or designs requiring automotive-grade component qualification.

RMCF2010FT73R2 (Stackpole Electronics Inc RMCF Series)

This part satisfies all core electrical parameters (73.2 Ohms ±1%, ±100ppm/°C, -55°C to 155°C) and package requirements (2010 metric). The 0.75W power rating provides thermal performance equivalent to or exceeding the main part. AEC-Q200 automotive qualification is included, meeting automotive reliability standards. RoHS3 and MSL 1 compliance are present. Height specification (0.028" maximum) is consistent with the Vishay part. This substitute is suitable for automotive applications or designs requiring automotive-grade component qualification.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-0773R2L replace RC5025F73R2CS in all applications?

A: Yes, within the specified electrical and thermal operating envelope. The RC2010FK-0773R2L provides equal or superior performance due to its higher power rating (0.75W versus 0.667W) in the identical 2010 package format. Both parts share matching resistance (73.2 Ohms), tolerance (±1%), temperature coefficient (±100ppm/°C), and operating range (-55°C to 155°C). Verify that your application does not require automotive-specific qualification; if automotive qualification is needed, select CRCW201073R2FKEF or RMCF2010FT73R2 instead.

Q: What is the difference between the main part and the substitute parts in terms of power rating?

A: The RC5025F73R2CS is rated for 0.667W (2/3W) continuous power dissipation. All three substitute parts are rated for 0.75W (3/4W). Higher power ratings indicate greater thermal capacity in the same physical package. A 0.75W-rated part can safely dissipate the same power as a 0.667W-rated part with lower junction temperature rise, providing improved reliability margin. No circuit redesign is required when substituting a higher-rated part for a lower-rated part in the same package.

Q: Are the substitute parts physically compatible with the RC5025F73R2CS footprint?

A: Yes. All substitute parts use the 2010 (5025 Metric) package format with identical length (0.197" / 5.00mm) and width (0.098" / 2.50mm) dimensions. Height specifications vary slightly: RC5025F73R2CS maximum 0.026" (0.66mm), RC2010FK-0773R2L maximum 0.026" (0.65mm), CRCW201073R2FKEF maximum 0.028" (0.70mm), and RMCF2010FT73R2 maximum 0.028" (0.70mm). These height variations are within standard PCB design tolerances and do not affect footprint compatibility or soldering process parameters.

Q: Which substitute part should I select for automotive applications?

A: For automotive applications, select either CRCW201073R2FKEF (Vishay Dale) or RMCF2010FT73R2 (Stackpole Electronics Inc). Both parts carry AEC-Q200 automotive qualification, indicating compliance with automotive reliability standards and environmental stress testing requirements. The RC2010FK-0773R2L does not specify automotive qualification and should not be used in automotive designs unless your application does not require AEC-Q200 compliance.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Moisture Sensitivity Level 1) with unlimited rating indicates that the component has no moisture sensitivity restrictions. These parts do not require special moisture-controlled storage, handling, or baking procedures prior to soldering. Standard warehouse storage conditions are acceptable. This specification applies to all four parts (main and substitutes) and simplifies supply chain management and assembly logistics.

Q: Can I mix different manufacturers' parts in the same production batch?

A: Yes, all four parts meet identical electrical specifications (73.2 Ohms ±1%, ±100ppm/°C, -55°C to 155°C) and package format (2010 metric). From an electrical and thermal perspective, they are interchangeable. However, verify that your quality assurance procedures and design documentation permit multi-source component usage. If your design specifies a single manufacturer part number, obtain engineering approval before introducing alternative manufacturers into production.

Q: What is the difference between Tape & Reel and Bulk packaging?

A: The RC5025F73R2CS is supplied in Bulk packaging (loose components), while all substitute parts are supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated pick-and-place assembly equipment and provides better component protection during handling and storage. Bulk packaging requires manual handling or custom feeding systems. If your assembly process uses automated equipment, Tape & Reel packaging is preferred. If manual assembly is used, either format is acceptable.

Q: Are all parts RoHS3 compliant?

A: Yes. The RC5025F73R2CS and all three substitute parts (RC2010FK-0773R2L, CRCW201073R2FKEF, RMCF2010FT73R2) are RoHS3 compliant. This certification confirms that the parts do not contain restricted substances (lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, or polybrominated diphenyl ethers) above specified thresholds. RoHS3 compliance is required for most commercial and industrial applications in regulated markets.
