Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F2261CS is determined by strict adherence to the following parameters:

Critical Matching Parameters:

• Resistance value: 2.26 kOhms
• Tolerance: ±1%
• Package / Case: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Status: ROHS3 Compliant

Allowable Variation:

• Power Rating: Substitute parts rated at 0.75W (3/4W) are acceptable as this represents a higher power capability within the same package footprint, providing equal or superior performance margin.

All identified substitute parts maintain identical electrical specifications and package dimensions while meeting or exceeding the thermal and environmental requirements of the original component.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CRCW20102K26FKEF (Vishay Dale) and RMCF2010FT2K26 (Stackpole Electronics Inc) are functionally equivalent to the RC5025F2261CS. Both maintain Active product status, ensuring continued availability and manufacturing support. These parts feature automotive AEC-Q200 qualification, providing additional reliability assurance for demanding applications. The increased power rating of 0.75W (3/4W) offers superior thermal margin compared to the original 0.667W specification.

Secondary Substitute (Legacy Status):

ERJ-12SF2261U (Panasonic Electronic Components) meets all electrical and mechanical compatibility requirements but carries a "Not For New Designs" product status designation. This part is suitable for replacement applications and field service scenarios where existing inventory exists, but should not be selected for new circuit designs requiring long-term component availability.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original component. Moisture Sensitivity Level 1 (Unlimited) is consistent across all options, eliminating moisture handling concerns during assembly and storage.

Frequently Asked Questions (FAQ)

Q: Can CRCW20102K26FKEF replace RC5025F2261CS in existing designs?

A: Yes. CRCW20102K26FKEF is electrically and mechanically compatible. Both components share identical resistance (2.26 kOhms), tolerance (±1%), package footprint (2010/5025 Metric), and operating temperature range (-55°C ~ 155°C). The substitute's higher power rating (0.75W vs. 0.667W) provides additional thermal capability without affecting circuit performance.

Q: What is the difference in height between the main part and substitutes?

A: RC5025F2261CS has a maximum seated height of 0.026" (0.66mm), while substitute parts CRCW20102K26FKEF, ERJ-12SF2261U, and RMCF2010FT2K26 have a maximum seated height of 0.028" (0.70mm). This 0.002" (0.04mm) difference is within standard PCB assembly tolerances and does not affect board-level compatibility.

Q: Are automotive-qualified substitutes suitable for non-automotive applications?

A: Yes. CRCW20102K26FKEF and RMCF2010FT2K26 carry AEC-Q200 automotive qualification, which represents a superset of reliability requirements. These parts are suitable for any application requiring the specified electrical and environmental parameters, regardless of end-use sector.

Q: Why is ERJ-12SF2261U marked "Not For New Designs"?

A: ERJ-12SF2261U carries a "Not For New Designs" status, indicating that Panasonic has transitioned this product line. While the part remains functionally equivalent and suitable for replacement or repair applications, new circuit designs should prioritize CRCW20102K26FKEF or RMCF2010FT2K26 to ensure long-term supply chain stability.

Q: Do all substitute parts have the same moisture sensitivity rating?

A: Yes. All parts, including the main component RC5025F2261CS and all substitutes, are rated at Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related handling restrictions during assembly or storage.

Q: What packaging formats are available for these substitutes?

A: RC5025F2261CS is supplied in standard packaging format. Substitute parts CRCW20102K26FKEF, ERJ-12SF2261U, and RMCF2010FT2K26 are available in Tape & Reel (TR) format, which is standard for high-volume SMD assembly operations.
