Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F2741CS is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 2.74 kOhms
• Tolerance: ±1%
• Package / Case: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

Allowable Variation Parameters:

• Power Rating: Substitutes rated at 0.75W (3/4W) or higher are acceptable as they exceed the original 0.667W specification
• Features: Substitutes may include additional certifications (Automotive AEC-Q200) or enhanced moisture resistance without affecting compatibility
• Manufacturer: Different manufacturers are acceptable provided all mandatory parameters align

All substitute parts listed maintain identical electrical characteristics and physical dimensions within the 2010 package specification, ensuring direct form-fit-function compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

AC2010FK-072K74L (YAGEO) and RC2010FK-072K74L (YAGEO) are recommended as primary substitutes. Both parts maintain Active product status and provide increased power rating (0.75W) compared to the original specification. AC2010FK-072K74L includes Automotive AEC-Q200 certification for applications requiring automotive-grade reliability. RC2010FK-072K74L offers standard industrial-grade performance without automotive qualification.

Secondary Substitute (Active Product Status):

CRCW20102K74FKEF (Vishay Dale) is an Active product with Automotive AEC-Q200 certification and higher inventory availability (30,719 pcs). This part is suitable for automotive and industrial applications requiring enhanced reliability standards.

Legacy Substitute (Not For New Designs):

ERJ-12SF2741U (Panasonic Electronic Components) carries a "Not For New Designs" product status classification. This part is electrically and mechanically compatible but should not be selected for new circuit designs. Existing designs currently using this component may continue operation with this part, but migration to Active-status alternatives is recommended for long-term supply chain stability.

All substitute parts are ROHS3 compliant with MSL 1 rating, ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can AC2010FK-072K74L replace RC5025F2741CS directly?

A: Yes. AC2010FK-072K74L is a direct substitute. Both parts share identical resistance (2.74 kOhms), tolerance (±1%), package (2010), composition (thick film), and operating temperature range (-55°C ~ 155°C). The substitute provides higher power rating (0.75W vs. 0.667W) and includes Automotive AEC-Q200 certification. Physical dimensions and electrical characteristics are compatible for direct PCB substitution.

Q: What is the difference between RC2010FK-072K74L and AC2010FK-072K74L?

A: Both are YAGEO 2.74 kOhms ±1% resistors in 2010 package with 0.75W power rating. AC2010FK-072K74L includes Automotive AEC-Q200 certification and is designated for automotive applications. RC2010FK-072K74L is standard industrial-grade without automotive qualification. Electrical performance and physical dimensions are identical.

Q: Why is ERJ-12SF2741U marked "Not For New Designs"?

A: ERJ-12SF2741U carries a "Not For New Designs" product status from Panasonic Electronic Components. This classification indicates the manufacturer is phasing out this product line. While the part is electrically and mechanically compatible with RC5025F2741CS, new circuit designs should utilize Active-status alternatives such as AC2010FK-072K74L, RC2010FK-072K74L, or CRCW20102K74FKEF to ensure long-term component availability and supply chain continuity.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (AC2010FK-072K74L, RC2010FK-072K74L, CRCW20102K74FKEF, and ERJ-12SF2741U) are ROHS3 compliant with MSL 1 (Unlimited) rating, matching the original RC5025F2741CS specification.

Q: What is the maximum height difference between substitute parts?

A: The original RC5025F2741CS has a maximum seated height of 0.026" (0.66mm). YAGEO substitutes (AC2010FK-072K74L and RC2010FK-072K74L) maintain 0.026" (0.65mm) height. Vishay Dale (CRCW20102K74FKEF) and Panasonic (ERJ-12SF2741U) have maximum heights of 0.028" (0.70mm). This 0.002" (0.04mm) difference is within standard PCB assembly tolerances and does not affect form-fit-function compatibility.

Q: Can I use CRCW20102K74FKEF in automotive applications?

A: Yes. CRCW20102K74FKEF is Automotive AEC-Q200 certified and rated for -55°C ~ 155°C operating temperature. This part is suitable for automotive and industrial applications requiring enhanced reliability standards.

Q: What is the inventory status of substitute parts?

A: AC2010FK-072K74L has 4,960 pcs in stock. RC2010FK-072K74L has 8,687 pcs in stock. CRCW20102K74FKEF has 30,719 pcs in stock. ERJ-12SF2741U has 5,696 pcs in stock. All parts are available as new original components.
