Substitute Part Grouping Explanation

Substitute parts for the RC5025F2740CS are identified based on strict electrical and mechanical parameter matching. The substitution logic requires:

Mandatory Matching Parameters:

• Resistance value: 274 Ohms (exact match)
• Tolerance: ±1% (exact match)
• Package format: 2010 (5025 Metric) (exact match)
• Composition: Thick Film (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Operating temperature range: -55°C to +155°C (exact match)
• RoHS3 compliance (regulatory requirement)
• Moisture sensitivity level: MSL 1 (exact match)

Allowable Variation Parameters:

• Power rating: Substitute parts may have equal or higher power rating (0.667W or greater)
• Packaging format: Tape & Reel (TR) acceptable as alternative to standard packaging
• Additional certifications: Automotive AEC-Q200 qualification is an enhancement, not a restriction

The AC2010FK-07274RL from YAGEO qualifies as a direct substitute because it maintains all mandatory electrical parameters while providing an upgraded power rating (0.75W versus 0.667W) and automotive-grade certification (AEC-Q200), making it suitable for applications requiring enhanced thermal performance or automotive-qualified components.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (RC5025F2740CS): Select the RC5025F2740CS when Samsung Electro-Mechanics supply chain is preferred, standard industrial-grade certification is sufficient, and the 0.667W power rating meets application thermal requirements. This part maintains Active product status with established manufacturing continuity.

Substitute Part Selection (AC2010FK-07274RL): Select the AC2010FK-07274RL when:

• Higher thermal dissipation capacity is required (0.75W rating provides 12.5% additional power handling)
• Automotive-grade reliability is specified (AEC-Q200 certification)
• YAGEO supply chain offers better availability or lead time
• Tape & Reel packaging format is required for automated assembly processes

Both parts satisfy RoHS3 regulatory requirements and maintain identical electrical performance characteristics (resistance, tolerance, temperature coefficient, operating range). The substitute part's enhanced power rating and automotive certification do not create incompatibility; they represent performance enhancements suitable for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can AC2010FK-07274RL be used as a direct replacement for RC5025F2740CS in existing designs?

A: Yes. Both parts share identical resistance value (274 Ohms), tolerance (±1%), package format (2010/5025 Metric), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to +155°C). The substitute part's higher power rating (0.75W versus 0.667W) and automotive certification represent enhancements that do not compromise compatibility. PCB footprints and electrical performance are functionally equivalent.

Q: What is the significance of the power rating difference between these parts?

A: The RC5025F2740CS is rated at 0.667W (2/3W), while the AC2010FK-07274RL is rated at 0.75W (3/4W). This 0.083W difference represents additional thermal dissipation capacity in the substitute part. For applications operating at or below the original 0.667W specification, both parts perform identically. For applications requiring higher power dissipation, the substitute part provides additional margin.

Q: Are there packaging differences between these parts?

A: The RC5025F2740CS is supplied in standard packaging format, while the AC2010FK-07274RL is supplied in Tape & Reel (TR) format. Both maintain identical 2010 (5025 Metric) package dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm). Tape & Reel format is optimized for automated pick-and-place assembly; standard packaging is suitable for manual or mixed assembly processes.

Q: What does AEC-Q200 certification mean for the substitute part?

A: AEC-Q200 is an automotive industry qualification standard for passive components. The AC2010FK-07274RL's AEC-Q200 certification indicates compliance with automotive reliability, temperature cycling, and environmental stress testing requirements. This certification is not required for industrial applications but provides additional assurance for automotive or mission-critical applications.

Q: Are both parts RoHS3 compliant?

A: Yes. Both RC5025F2740CS and AC2010FK-07274RL are ROHS3 Compliant, meeting current regulatory requirements for hazardous substance restrictions in electronic components.

Q: What is MSL 1 (Unlimited) moisture sensitivity rating?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. Both parts carry this rating, eliminating moisture-related handling constraints for inventory management and assembly processes.
