Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F24R9CS is determined by strict adherence to the following criteria:

Mandatory Matching Parameters:

• Resistance value: 24.9 Ohms
• 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
• Moisture Sensitivity Level: MSL 1 (Unlimited)

Allowable Variation Parameters:

• Power Rating: Substitute parts rated at 0.75W (3/4W) or higher are acceptable, as they provide equal or greater power dissipation capability within the same package footprint
• Packaging Format: Original part supplied in bulk; substitutes may be supplied in Tape & Reel (TR) format without affecting electrical or mechanical compatibility
• Product Status: Active or Not For New Designs status does not affect functional equivalence
• Automotive Qualification: AEC-Q200 certification on substitute parts represents an additional qualification level and does not preclude substitution

Parameter Comparison

Engineering Selection Recommendations

CRCW201024R9FKEF (Vishay Dale) is the primary substitute for new designs. This part maintains all mandatory electrical and mechanical parameters while providing increased power rating (0.75W versus 0.667W). Active product status ensures continued availability and manufacturing support. AEC-Q200 automotive qualification provides additional reliability assurance for applications requiring automotive-grade components. Tape & Reel packaging is standard for production volume applications.

ERJ-12SF24R9U (Panasonic Electronic Components) is functionally equivalent but carries Not For New Designs product status. This designation indicates the manufacturer is not recommending this part for new circuit designs, though existing inventory remains available. The part meets all electrical and mechanical specifications with identical power rating upgrade (0.75W) and AEC-Q200 qualification. Selection of this part should be limited to replacement or legacy system applications where design continuity is required.

Both substitute parts accommodate the same PCB footprint and reflow soldering processes as the original RC5025F24R9CS. The marginal height increase (0.028" versus 0.026" seated height) is within standard PCB assembly tolerances and does not affect component placement or clearance in typical 2010 package applications.

Frequently Asked Questions (FAQ)

Q: Can CRCW201024R9FKEF replace RC5025F24R9CS in existing designs?

A: Yes. The CRCW201024R9FKEF maintains identical resistance value (24.9 Ohms), tolerance (±1%), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and package footprint (2010 / 5025 Metric). The increased power rating (0.75W versus 0.667W) provides additional thermal margin without affecting circuit performance.

Q: What is the difference between the two substitute parts?

A: Both CRCW201024R9FKEF and ERJ-12SF24R9U meet identical electrical specifications. The primary difference is product status: CRCW201024R9FKEF is Active (recommended for new designs), while ERJ-12SF24R9U is Not For New Designs (suitable for replacement applications only). Both include AEC-Q200 automotive qualification.

Q: Does the height difference between parts affect PCB assembly?

A: The seated height difference (0.026" for RC5025F24R9CS versus 0.028" for both substitutes) is 0.002" (0.04mm). This variation is within standard PCB assembly tolerances and does not require design modification for typical applications using 2010 package components.

Q: Are all three parts RoHS3 compliant?

A: Yes. RC5025F24R9CS, CRCW201024R9FKEF, and ERJ-12SF24R9U are all ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can I use ERJ-12SF24R9U for new product development?

A: The ERJ-12SF24R9U carries Not For New Designs status. For new product development, CRCW201024R9FKEF is the recommended substitute, as it maintains Active product status and ensures long-term manufacturing availability.

Q: What packaging formats are available for these parts?

A: RC5025F24R9CS is supplied in bulk packaging. CRCW201024R9FKEF and ERJ-12SF24R9U are supplied in Tape & Reel (TR) format, which is standard for production volume assembly processes.
