RC5025F9090CS Equivalent & Substitute Parts

Part Overview

The RC5025F9090CS is a 909 Ohms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 2010 (5025 Metric) package format. This component is rated for 0.667W (2/3W) continuous power dissipation and features moisture-resistant construction with an operating temperature range of -55°C to 155°C. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and package compatibility align with the main part's core parameters. Alternative sources become necessary for supply chain continuity, inventory availability, or when design requirements permit higher power ratings within the same package footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F9090CS is determined by strict alignment of the following core parameters:

Mandatory Matching Parameters:

• Resistance value: 909 Ohms
• Tolerance: ±1%
• Package / Case: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Number of Terminations: 2
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Power Rating: Substitute parts may exceed the main part's 0.667W rating while maintaining identical physical dimensions and thermal characteristics within the 2010 package specification.

The identified substitute parts CRCW2010909RFKEF and ERJ-12SF9090U meet all mandatory parameters. Both components feature identical resistance, tolerance, package dimensions, and operating specifications. The substitute parts are rated for 0.75W (3/4W), which represents a higher power capability within the same package footprint and does not compromise compatibility or performance in applications designed for the RC5025F9090CS.

Parameter Comparison

Engineering Selection Recommendations

CRCW2010909RFKEF (Vishay Dale) is the primary substitute for the RC5025F9090CS. This component maintains Active product status and carries AEC-Q200 automotive qualification. The 0.75W power rating provides enhanced thermal margin within the identical 2010 package footprint. All electrical and mechanical parameters align with the main part specification. ROHS3 compliance and unlimited moisture sensitivity level are maintained.

ERJ-12SF9090U (Panasonic Electronic Components) is a secondary substitute option. This part carries AEC-Q200 automotive qualification and matches all core electrical and mechanical specifications. However, the product status is designated as "Not For New Designs," which restricts its application to legacy system support or replacement scenarios only. The 0.75W power rating and identical package dimensions provide functional equivalence to the RC5025F9090CS.

For new design implementations, CRCW2010909RFKEF is the recommended substitute due to its Active product status. For existing systems or legacy applications, ERJ-12SF9090U remains functionally compatible despite its restricted design status.

Frequently Asked Questions (FAQ)

Q: Can CRCW2010909RFKEF be used as a direct replacement for RC5025F9090CS?

A: Yes. Both components share identical resistance (909 Ohms), tolerance (±1%), package dimensions (2010 / 5025 Metric), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The CRCW2010909RFKEF features a higher power rating (0.75W versus 0.667W) within the same physical package, which does not compromise compatibility.

Q: What is the difference in height between the main part and substitute parts?

A: The RC5025F9090CS has a maximum seated height of 0.026" (0.66mm). Both substitute parts (CRCW2010909RFKEF and ERJ-12SF9090U) have a maximum seated height of 0.028" (0.70mm). This 0.002" (0.04mm) difference is within standard PCB assembly tolerances and does not affect placement or functionality.

Q: Why is ERJ-12SF9090U marked as "Not For New Designs"?

A: The ERJ-12SF9090U carries a "Not For New Designs" product status designation from Panasonic. This indicates the part is available for replacement and legacy applications but should not be selected for new circuit designs. For new implementations, CRCW2010909RFKEF is the appropriate substitute choice.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The RC5025F9090CS, CRCW2010909RFKEF, and ERJ-12SF9090U are all ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Q: What packaging formats are available for the substitute parts?

A: CRCW2010909RFKEF is supplied in Tape & Reel (TR) format. ERJ-12SF9090U is also supplied in Tape & Reel (TR) format. The RC5025F9090CS packaging format is not specified in the provided data.

Q: Can the higher power rating of substitute parts affect circuit performance?

A: No. The 0.75W power rating of CRCW2010909RFKEF and ERJ-12SF9090U represents increased thermal capability within the identical 2010 package. This does not alter electrical performance, resistance value, or tolerance characteristics. The higher power rating provides additional thermal margin and does not negatively impact circuits designed for the 0.667W RC5025F9090CS.
