RC5025F8250CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F8250CS is a 825 Ohm ±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 with moisture-resistant construction and operates across the temperature range of -55°C to 155°C. The part maintains Active product status with 694 units currently in stock.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package format, resistance value, tolerance, and operating temperature range. Alternative sources become necessary due to inventory availability, supply chain optimization, or specific application requirements such as automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F8250CS is determined by strict adherence to the following criteria:

Mandatory Matching Parameters:

• Resistance value: 825 Ohms
• Tolerance: ±1%
• Package format: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Number of terminations: 2
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Allowable Variation:

• Power rating: Substitute parts rated at 0.75W (3/4W) or higher are acceptable, as they exceed the 0.667W requirement of the main part
• Packaging format: Original packaging (bulk) or Tape & Reel (TR) are both acceptable
• Automotive qualification: AEC-Q200 certification is an additional feature that does not disqualify substitution

The identified substitute parts CRCW2010825RFKEF and ERJ-12SF8250U meet all mandatory parameters while offering higher power ratings and automotive-grade qualification.

Engineering Selection Recommendations

Primary Substitute: CRCW2010825RFKEF (Vishay Dale)

The CRCW2010825RFKEF is the preferred substitute for the RC5025F8250CS. This part maintains Active product status, ensuring long-term availability and supply chain stability. It meets all mandatory electrical and mechanical parameters with identical resistance, tolerance, temperature coefficient, and operating range. The higher power rating of 0.75W provides additional thermal margin beyond the 0.667W requirement. AEC-Q200 automotive qualification adds robustness for demanding applications. Packaging in Tape & Reel format supports automated assembly processes.

Secondary Substitute: ERJ-12SF8250U (Panasonic Electronic Components)

The ERJ-12SF8250U meets all mandatory electrical and mechanical specifications and carries AEC-Q200 automotive qualification. However, this part is designated "Not For New Designs," indicating that Panasonic has discontinued active development and support. While existing inventory of 872 units is available, this part should be selected only when CRCW2010825RFKEF is unavailable and the application does not require long-term supply assurance.

Selection Criteria Summary:

• For new designs and long-term production: Select CRCW2010825RFKEF
• For legacy system maintenance or temporary supply gaps: ERJ-12SF8250U is acceptable
• All substitutes are mechanically compatible with PCB layouts designed for 2010 package format
• Height variation (0.66mm vs. 0.70mm) is negligible for standard PCB assembly

Frequently Asked Questions (FAQ)

Q: Can CRCW2010825RFKEF directly replace RC5025F8250CS in existing designs?

A: Yes. Both parts share identical electrical specifications (825 Ohms ±1%, ±100ppm/°C, -55°C to 155°C operating range) and mechanical compatibility (2010 package, 5.00mm x 2.50mm footprint). The 0.04mm height difference (0.70mm vs. 0.66mm) is within standard PCB assembly tolerances and does not affect circuit performance or board layout.

Q: What is the significance of the higher power rating on substitute parts?

A: The CRCW2010825RFKEF and ERJ-12SF8250U are rated at 0.75W compared to the RC5025F8250CS at 0.667W. A higher power rating indicates greater thermal capacity and margin for safety. Substituting a higher-rated part does not degrade circuit performance; it only provides additional thermal headroom. The actual power dissipation in the circuit remains determined by the applied voltage and current, not the component rating.

Q: Why is ERJ-12SF8250U marked "Not For New Designs"?

A: This designation indicates that Panasonic has transitioned this part to end-of-life status and is not actively developing or promoting it for new applications. While current inventory exists, future availability cannot be guaranteed. For new product designs, CRCW2010825RFKEF is the recommended choice to ensure supply continuity throughout the product lifecycle.

Q: Are there any compliance differences between the three parts?

A: All three parts are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (Unlimited moisture sensitivity). The RC5025F8250CS features moisture-resistant construction, while CRCW2010825RFKEF and ERJ-12SF8250U carry AEC-Q200 automotive qualification. These are complementary features that do not conflict; AEC-Q200 qualification includes moisture resistance requirements.

Q: Can these parts be used interchangeably in automated pick-and-place assembly?

A: Yes. All three parts are available in Tape & Reel packaging suitable for automated assembly equipment. The identical 2010 package footprint and similar height specifications ensure compatibility with standard feeder systems and placement tolerances. Verify that your assembly equipment supports the specific tape format (8mm or 12mm) specified by your supplier.

Q: What is the impact of the ±100ppm/°C temperature coefficient on circuit stability?

A: The temperature coefficient specifies the resistance change per degree Celsius across the operating range. At ±100ppm/°C, a 825 Ohm resistor will vary by approximately ±0.0825 Ohms per degree Celsius. Across the full -55°C to 155°C range (210°C span), maximum resistance drift is approximately ±17.3 Ohms or ±2.1% from nominal. This specification is identical across all three parts and is typical for thick film chip resistors in this class.
