RC5025F2052CS Equivalent & Substitute Parts

Part Overview

The RC5025F2052CS is a 20.5 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated for 0.667W (2/3W) power dissipation in a 2010 (5025 Metric) surface mount package. This component is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the same resistance value, tolerance, package footprint, and operating temperature range. The primary substitute identified is the ERJ-12SF2052U from Panasonic Electronic Components, which shares identical resistance, tolerance, and package specifications while offering higher power rating and automotive qualification.

Substitute Part Grouping Explanation

Substitution logic for the RC5025F2052CS is based on strict electrical and mechanical parameter matching:

Primary Substitution Criteria (Non-Negotiable):

• Resistance value: 20.5 kOhms
• Tolerance: ±1%
• Package: 2010 (5025 Metric)
• Composition: Thick Film
• Operating temperature range: -55°C ~ 155°C minimum
• Temperature coefficient: ±100ppm/°C

Secondary Compatibility Factors (Allowable Variation):

• Power rating: Substitute must equal or exceed 0.667W
• Product status: Active or Not For New Designs both acceptable for equivalent substitution
• Certifications: RoHS3 compliance required; additional certifications (AEC-Q200) are additive benefits

The ERJ-12SF2052U qualifies as a direct substitute because it maintains all primary criteria while exceeding the power rating (0.75W vs. 0.667W) and adding automotive qualification without compromising any electrical or mechanical specifications.

Engineering Selection Recommendations

RC5025F2052CS (Primary Selection): The RC5025F2052CS maintains Active product status, indicating ongoing manufacturer support and availability. This component is the preferred choice for new designs requiring standard industrial-grade thick film resistors with no automotive qualification requirements. Active status ensures long-term supply chain stability and consistent manufacturing processes.

ERJ-12SF2052U (Substitute Selection): The ERJ-12SF2052U is suitable as a substitute when the RC5025F2052CS is unavailable or when design requirements benefit from higher power rating (0.75W vs. 0.667W) and automotive AEC-Q200 qualification. The "Not For New Designs" status indicates this part remains available for replacement and legacy applications but is not recommended for new product development by the manufacturer. The 0.04mm height difference (0.70mm vs. 0.66mm) is within typical PCB assembly tolerances and does not affect mechanical compatibility.

Both parts maintain identical electrical performance across the specified operating temperature range and comply with RoHS3 environmental standards. Selection between these parts should be based on supply availability, cost considerations, and whether automotive qualification is required for the application.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-12SF2052U replace the RC5025F2052CS in existing designs?

A: Yes. The ERJ-12SF2052U is electrically and mechanically compatible. Both parts share identical resistance (20.5 kOhms), tolerance (±1%), package footprint (2010/5025 Metric), operating temperature range (-55°C ~ 155°C), and temperature coefficient (±100ppm/°C). The higher power rating (0.75W vs. 0.667W) and automotive certification of the Panasonic part do not create incompatibility; they represent equal or superior performance characteristics.

Q: What is the significance of the "Not For New Designs" status on the ERJ-12SF2052U?

A: This status indicates that Panasonic does not recommend the ERJ-12SF2052U for new product development. However, it remains available for replacement, repair, and legacy applications. For new designs, the RC5025F2052CS (Active status) is the preferred choice. For existing designs or when the Samsung part is unavailable, the Panasonic substitute is technically qualified.

Q: Are there dimensional compatibility concerns between these parts?

A: No. Both parts use the identical 2010 (5025 Metric) package with dimensions of 0.197" L x 0.098" W (5.00mm x 2.50mm). The maximum seated height differs by 0.04mm (0.66mm vs. 0.70mm), which is negligible for standard PCB assembly and does not affect component placement or clearance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the RC5025F2052CS and ERJ-12SF2052U are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS codes (8533.21.0030). The ERJ-12SF2052U includes additional AEC-Q200 automotive qualification, which is a supplementary certification that does not conflict with standard industrial applications.

Q: What is the tolerance specification, and why does it matter for substitution?

A: Both parts are specified at ±1% tolerance, meaning the actual resistance value will fall within 20.295 kOhms to 20.705 kOhms. This tight tolerance is critical for circuit accuracy and must be maintained in any substitute. Parts with different tolerance specifications (such as ±5% or ±10%) would not be acceptable substitutes.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both parts maintain the same operating temperature range (-55°C ~ 155°C) and identical temperature coefficient (±100ppm/°C), ensuring consistent resistance stability across the full environmental envelope. No derating or performance degradation occurs when substituting between these parts in temperature-critical applications.
