RC5025F5903CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F5903CS is a 590 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 2010 (5025 Metric) package format with a power rating of 0.667W (2/3W). This component is classified as Active product status and is RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the same resistance value, tolerance, package dimensions, and operating temperature range. Alternative sources become necessary for supply chain continuity, inventory availability, or specific application requirements such as automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F5903CS is determined by strict alignment of the following parameters:

Mandatory Matching Parameters:

• Resistance value: 590 kOhms
• Tolerance: ±1%
• Package / Case: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100 ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Physical dimensions: 5.00mm L × 2.50mm W
• Number of Terminations: 2

Allowable Variation Parameters:

• Power rating: Substitute parts may have equal or higher power rating (0.667W or greater)
• Height - Seated: Minor variations within component tolerance
• Packaging format: Original part supplied in cut tape; substitutes may be supplied in Tape & Reel (TR)
• Compliance certifications: Substitutes may include additional certifications (e.g., AEC-Q200 automotive qualification)
• Product status: Active or Not For New Designs status does not disqualify substitution eligibility

Identified substitute parts maintain electrical equivalence through identical resistance, tolerance, and thermal characteristics while accommodating higher power dissipation capability and enhanced automotive qualification where applicable.

Parameter Comparison

Engineering Selection Recommendations

CRCW2010590KFKEF (Vishay Dale) is the primary substitute option. This part maintains full electrical equivalence with the RC5025F5903CS while providing increased power dissipation capability (0.75W versus 0.667W). The CRCW2010590KFKEF carries Active product status, ROHS3 compliance, and AEC-Q200 automotive qualification. The 0.04mm increase in seated height (0.70mm versus 0.66mm) remains within standard component tolerance and does not affect PCB layout compatibility for standard 2010 package footprints. Tape & Reel packaging is suitable for automated assembly processes.

ERJ-12SF5903U (Panasonic Electronic Components) provides electrical equivalence and identical thermal performance. However, this part carries "Not For New Designs" product status and is RoHS non-compliant. Selection of ERJ-12SF5903U is restricted to legacy system maintenance, repair operations, or applications where RoHS compliance is not required. The AEC-Q200 automotive qualification is present but does not offset the compliance limitations.

For new design implementations and applications requiring RoHS3 compliance, CRCW2010590KFKEF is the recommended substitute. For legacy or non-regulated applications where RoHS compliance is not mandatory, ERJ-12SF5903U remains electrically and mechanically compatible.

Frequently Asked Questions (FAQ)

Q: Can CRCW2010590KFKEF be used as a direct replacement for RC5025F5903CS in existing designs?

A: Yes. Both parts share identical resistance (590 kOhms), tolerance (±1%), package dimensions (5.00mm × 2.50mm), and operating temperature range (-55°C to 155°C). The CRCW2010590KFKEF provides higher power rating (0.75W versus 0.667W), which is compatible with applications designed for the lower-rated component. The 0.04mm height difference is within standard PCB assembly tolerance.

Q: What is the significance of the power rating difference between RC5025F5903CS (0.667W) and the substitute parts (0.75W)?

A: The substitute parts have higher power dissipation capability. A component rated for higher power can safely operate in circuits designed for lower power dissipation. The reverse substitution (using a lower-rated part in a higher-power application) is not permitted.

Q: Why is ERJ-12SF5903U marked "Not For New Designs"?

A: "Not For New Designs" indicates that the manufacturer has discontinued active development and recommends alternative parts for new product development. This part remains available for existing inventory and legacy system support but should not be selected for new circuit designs.

Q: Does the RoHS non-compliance of ERJ-12SF5903U affect its electrical performance?

A: No. RoHS compliance status relates to material composition and environmental regulations, not electrical performance. However, RoHS non-compliant parts cannot be used in applications or markets requiring RoHS3 certification.

Q: Are the substitute parts available in the same packaging format as the original RC5025F5903CS?

A: The RC5025F5903CS is supplied in cut tape format. Both substitute parts (CRCW2010590KFKEF and ERJ-12SF5903U) are supplied in Tape & Reel (TR) format, which is standard for automated assembly. Cut tape can be obtained through secondary processing if required for manual assembly operations.

Q: What does AEC-Q200 automotive qualification mean?

A: AEC-Q200 is an automotive industry standard qualification that certifies components for use in automotive applications. It includes enhanced reliability testing and temperature cycling requirements. Components with AEC-Q200 qualification are suitable for automotive and high-reliability applications but can also be used in non-automotive applications.

Q: Can these parts be used interchangeably in the same PCB assembly?

A: Yes, provided the PCB footprint is designed for the 2010 (5025 Metric) package. All three parts share identical footprint dimensions. Automated pick-and-place equipment can handle both cut tape and Tape & Reel formats with appropriate feeder configuration.
