Substitution eligibility is determined by strict adherence to the following criteria:

Mandatory Matching Parameters:

• Resistance value: 249 Ohms
• Tolerance: ±1%
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Package Format: 2010 (5025 Metric)
• Physical Dimensions: 5.00mm × 2.50mm
• Termination Count: 2
• Composition: Thick Film
• RoHS Compliance: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

Allowable Variation:

• Power Rating: Substitute parts with equal or higher power rating (0.75W/3/4W) are acceptable as they provide equivalent or superior thermal performance within the same package envelope.

Substitute Parts Identified:

1. RC2010FK-07249RL (YAGEO) – Upgrade substitute with 0.75W power rating
2. CRCW2010249RFKEF (Vishay Dale) – Similar substitute with AEC-Q200 automotive qualification and 0.75W power rating
3. ERJ-12SF2490U (Panasonic Electronic Components) – Similar substitute with AEC-Q200 automotive qualification and 0.75W power rating; Not For New Designs status
4. RMCF2010FT249R (Stackpole Electronics Inc) – Similar substitute with AEC-Q200 automotive qualification and 0.75W power rating

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Direct Upgrade): RC2010FK-07249RL (YAGEO) is the recommended upgrade substitute. It maintains all electrical and mechanical specifications of the RC5025F2490CS while providing increased power rating (0.75W vs 0.667W) within the identical 2010 package footprint. Both components are Active status with equivalent RoHS3 compliance and MSL 1 ratings. This substitution provides thermal margin improvement without design modification.

Alternative Selections (Automotive-Qualified Options): CRCW2010249RFKEF (Vishay Dale) and RMCF2010FT249R (Stackpole Electronics Inc) are functionally equivalent substitutes with additional AEC-Q200 automotive qualification. Both maintain Active product status and are suitable for applications requiring automotive-grade reliability. These parts are electrically and mechanically interchangeable with the main part while offering enhanced qualification documentation.

Not Recommended for New Designs: ERJ-12SF2490U (Panasonic Electronic Components) carries "Not For New Designs" product status. While electrically and mechanically compatible, this part should not be selected for new circuit designs due to its discontinued design status. Existing designs currently using this part may continue operation, but migration to an Active-status substitute is advised for long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-07249RL replace RC5025F2490CS in existing designs without PCB modification? A: Yes. Both parts use the 2010 (5025 Metric) package with identical 5.00mm × 2.50mm footprint and 2-pin termination. PCB layout and footprint remain unchanged. The increased power rating (0.75W vs 0.667W) provides thermal performance improvement without design impact.

Q: What is the significance of the 0.75W power rating in substitute parts compared to the 0.667W main part? A: The 0.75W rating indicates higher power dissipation capability within the same physical package. This provides thermal margin and allows operation at higher current levels or ambient temperatures without exceeding component limits. Substitution with higher-rated parts is acceptable and does not degrade performance.

Q: Are CRCW2010249RFKEF and RMCF2010FT249R suitable for automotive applications? A: Yes. Both parts carry AEC-Q200 automotive qualification, indicating compliance with automotive reliability and quality standards. These parts are suitable for automotive circuit applications requiring qualified component documentation.

Q: Why is ERJ-12SF2490U marked "Not For New Designs"? A: This designation indicates the part is in end-of-life status and Panasonic has discontinued its recommendation for new circuit designs. While existing inventory may be available and the part remains electrically compatible, new designs should select from Active-status alternatives (RC2010FK-07249RL, CRCW2010249RFKEF, or RMCF2010FT249R) to ensure long-term supply chain availability.

Q: Do all substitute parts maintain the same temperature coefficient and operating range? A: Yes. All identified substitutes maintain ±100ppm/°C temperature coefficient and -55°C to 155°C operating temperature range, ensuring equivalent thermal stability and performance across the full operating envelope.

Q: What is MSL 1 (Unlimited) moisture sensitivity rating? A: MSL 1 indicates the component has unlimited shelf life under standard storage conditions without moisture bake-out requirements. All identified parts maintain this rating, ensuring equivalent moisture handling and storage procedures.

Q: Are there height differences between the main part and substitutes that affect PCB assembly? A: Seated height varies slightly: RC5025F2490CS (0.66mm), RC2010FK-07249RL (0.65mm), CRCW2010249RFKEF (0.70mm), ERJ-12SF2490U (0.70mm), RMCF2010FT249R (0.70mm). These variations are within typical PCB assembly tolerances and do not require design modification. Confirm with assembly process specifications if height-critical applications exist.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All identified substitute parts maintain ROHS3 Compliant status, ensuring equivalent environmental and regulatory compliance with the main part.
