RC5025F8660CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F8660CS is a 866 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) 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 1033 units currently in stock inventory.

Substitute parts become necessary when primary inventory is depleted, when supply chain constraints affect availability, or when design requirements permit the use of components with equivalent or superior electrical and mechanical specifications within the same package family.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F8660CS is determined by strict adherence to the following parameters:

Critical Parameters (Must Match Exactly):

• Resistance value: 866 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

Allowable Variation Parameters:

• Power Rating: Substitute parts may equal or exceed the 0.667W specification
• Moisture Sensitivity Level: MSL 1 (Unlimited) is maintained across all substitutes
• RoHS Status: ROHS3 Compliant maintained across all substitutes

The identified substitute parts meet all critical parameters while offering equal or higher power dissipation capability, making them functionally interchangeable within the same circuit application space.

Parameter Comparison

Engineering Selection Recommendations

CRCW2010866RFKEF (Vishay Dale) is the primary substitute option. This component maintains Active product status, carries AEC-Q200 automotive qualification, and provides 0.75W power rating capability, exceeding the original specification. ROHS3 compliance and MSL 1 rating ensure compatibility with moisture-sensitive assembly environments. Current inventory of 8200 units supports sustained supply availability.

ERJ-12SF8660U (Panasonic Electronic Components) serves as a secondary substitute option. While this part carries AEC-Q200 automotive qualification and equivalent electrical specifications, it maintains "Not For New Designs" product status. This designation indicates the manufacturer is phasing out this component line. The 0.75W power rating and ROHS3 compliance remain valid for existing design implementations. Current inventory of 2520 units is available.

Selection between substitute parts should prioritize CRCW2010866RFKEF due to Active product status and superior long-term supply chain sustainability. ERJ-12SF8660U remains viable for legacy design support or temporary supply contingency only.

Frequently Asked Questions (FAQ)

Q: Can CRCW2010866RFKEF directly replace RC5025F8660CS in existing designs?

A: Yes. Both components share identical resistance (866 Ohms), tolerance (±1%), package format (2010/5025 Metric), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The CRCW2010866RFKEF provides higher power dissipation (0.75W versus 0.667W), which is a non-limiting advantage. Physical dimensions and termination count are equivalent.

Q: What is the significance of the height difference between RC5025F8660CS (0.66mm) and the substitute parts (0.70mm)?

A: The 0.04mm height variation falls within standard PCB assembly tolerances and does not affect circuit functionality or board-level compatibility. Both dimensions comply with 2010 package specifications. This difference does not create placement or soldering constraints in standard manufacturing processes.

Q: Why is ERJ-12SF8660U marked "Not For New Designs"?

A: This designation indicates Panasonic has discontinued active development and is transitioning this product line to end-of-life status. While the component remains functionally equivalent and currently in stock, it is not recommended for new circuit designs due to uncertain future availability. Existing designs may continue using this part until inventory depletion.

Q: Are all three parts ROHS3 compliant?

A: Yes. RC5025F8660CS, CRCW2010866RFKEF, and ERJ-12SF8660U all carry ROHS3 Compliant certification, confirming compliance with restricted substance directives across all manufacturing regions.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. These parts do not require special moisture-controlled storage, handling, or baking procedures prior to assembly. Standard warehouse storage conditions are acceptable.

Q: Can these resistors be used in automotive applications?

A: CRCW2010866RFKEF and ERJ-12SF8660U both carry AEC-Q200 automotive qualification. RC5025F8660CS does not list AEC-Q200 certification. For automotive applications requiring AEC-Q200 compliance, CRCW2010866RFKEF is the appropriate selection.
