Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F391CS is determined by strict alignment with the following core parameters:

Mandatory Matching Parameters:

• Resistance value: 390 Ohms
• Tolerance: ±1%
• Package format: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Moisture resistance capability
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Allowable Variation:

• Power rating: Substitute parts may have equal or higher power dissipation capacity (0.75W or greater is acceptable as an upgrade)
• Packaging format: Tape & Reel (TR) is compatible with the original component specification
• Additional certifications: Automotive AEC-Q200 qualification does not disqualify a part from substitution

The identified substitute parts RC2010FK-07390RL (YAGEO) and CRCW2010390RFKEF (Vishay Dale) meet all mandatory parameters and offer enhanced power ratings of 0.75W (3/4W), providing design margin improvement without compromising electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

RC5025F391CS (Samsung Electro-Mechanics) - Original Part

Use this part when the original design specification calls for a 0.667W (2/3W) power rating and Samsung Electro-Mechanics is the designated manufacturer. This part is Active status with established supply availability (1011 units in stock).

RC2010FK-07390RL (YAGEO) - Upgrade Substitute

This part is suitable as a direct substitute with enhanced power dissipation capability. The 0.75W (3/4W) rating provides increased thermal margin while maintaining identical electrical characteristics, package dimensions, and compliance certifications. YAGEO series RC_L offers robust supply availability (7360 units in stock). Select this part when design requirements permit higher power ratings or when YAGEO is an approved supplier in your qualification matrix.

CRCW2010390RFKEF (Vishay Dale) - Automotive-Grade Substitute

This part is appropriate for applications requiring AEC-Q200 automotive qualification. The CRCW series delivers 0.75W (3/4W) power rating with automotive-grade reliability standards. Height dimension is 0.028" (0.70mm), which remains within typical PCB assembly tolerances for 2010 package format. Select this part when automotive-grade certification is a design requirement or when Vishay Dale is the preferred supplier. Supply availability is 5198 units in stock.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-07390RL replace RC5025F391CS in my design?

A: Yes. RC2010FK-07390RL is a direct electrical and mechanical substitute. Both parts share identical resistance (390 Ohms), tolerance (±1%), package format (2010), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The substitute offers higher power rating (0.75W vs. 0.667W), which is an upgrade that does not compromise compatibility. Physical dimensions are equivalent within manufacturing tolerances.

Q: What is the difference between the YAGEO and Vishay Dale substitutes?

A: Both RC2010FK-07390RL (YAGEO) and CRCW2010390RFKEF (Vishay Dale) meet all electrical and mechanical requirements for substitution. The primary distinction is that CRCW2010390RFKEF carries AEC-Q200 automotive qualification, making it suitable for automotive applications. Both offer 0.75W power rating. Selection depends on supplier approval status and application requirements.

Q: Are there any height differences that affect PCB assembly?

A: Seated height differences are minimal. RC5025F391CS: 0.026" (0.66mm), RC2010FK-07390RL: 0.026" (0.65mm), CRCW2010390RFKEF: 0.028" (0.70mm). These variations fall within standard PCB assembly tolerances for 2010 package components and do not require design modification.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All three parts carry MSL rating 1 (Unlimited), indicating unlimited shelf life without moisture bake requirements. REACH status is REACH Unaffected for all parts, and all are ROHS3 compliant.

Q: Can I use CRCW2010390RFKEF in a non-automotive application?

A: Yes. CRCW2010390RFKEF meets all electrical and mechanical specifications for the RC5025F391CS application. AEC-Q200 certification is an additional qualification that does not restrict use in non-automotive designs. This part is suitable for any application requiring 390 Ohms ±1% in 2010 package format.

Q: What is the basis for determining substitution compatibility?

A: Substitution is based strictly on matching resistance value, tolerance, package format, composition, temperature coefficient, operating temperature range, moisture resistance, and compliance certifications. Power rating may be equal or higher. All three parts meet these criteria and are therefore interchangeable from an engineering standpoint.
