Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERJ-S1DF2211U are qualified based on the following criteria:

• Resistance value: 2.21 kOhms
• Tolerance: ±1%
• Power rating: 0.75W (3/4W)
• Package: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

All identified substitute parts meet these electrical and mechanical specifications, ensuring functional equivalence in circuit applications. Differences in manufacturing features (such as anti-sulfur coating versus moisture resistance) do not affect substitution eligibility when the core electrical parameters and package dimensions are identical.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed are active products with ROHS3 compliance and MSL rating 1, confirming their suitability for direct substitution. The ERJ-S1DF2211U (Panasonic) and RMCF2010FT2K21 (Stackpole) both carry AEC-Q200 automotive qualification, making them preferred choices for automotive applications. The CRCW20102K21FKEF (Vishay Dale) also holds AEC-Q200 certification. The RC2010FK-072K21L (YAGEO) features moisture-resistant construction without explicit automotive rating but maintains full electrical and mechanical compatibility. Selection should be based on availability, supply chain requirements, and specific application certifications needed.

Frequently Asked Questions (FAQ)

Q: Can CRCW20102K21FKEF replace ERJ-S1DF2211U directly? A: Yes. Both parts share identical resistance (2.21 kOhms), tolerance (±1%), power rating (0.75W), package (2010), and operating temperature range (-55°C ~ 155°C). Both are ROHS3 compliant with MSL 1 rating and AEC-Q200 automotive qualification.

Q: What is the difference between the anti-sulfur coating on the Panasonic part and the moisture-resistant feature on the YAGEO part? A: These are different manufacturing features that do not affect electrical substitution. Anti-sulfur coating protects against sulfur contamination in certain environments, while moisture resistance addresses humidity exposure. Both parts meet the same electrical and mechanical specifications required for circuit compatibility.

Q: Is the height difference between RC2010FK-072K21L (0.026") and other parts (0.028") significant? A: The height difference of 0.002" (0.05mm) is within typical PCB assembly tolerances and does not prevent substitution. All parts conform to the 2010 package standard and will function identically in circuit applications.

Q: Are all substitute parts available in the same packaging format? A: Yes. All four parts are supplied in Tape & Reel (TR) packaging, ensuring compatibility with automated assembly processes.

Q: Which substitute part should be selected for automotive applications? A: ERJ-S1DF2211U (Panasonic), CRCW20102K21FKEF (Vishay Dale), and RMCF2010FT2K21 (Stackpole) all carry AEC-Q200 automotive qualification. RC2010FK-072K21L (YAGEO) does not list explicit automotive rating but maintains full electrical compatibility.
