RC5025F8251CS

Part Overview

The RC5025F8251CS is an 8.25 kOhm ±1% thick film chip resistor rated at 0.667W (2/3W) in a 2010 (5025 Metric) surface mount package. This Samsung Electro-Mechanics component is currently active in production and features moisture-resistant construction suitable for general-purpose and industrial applications. Alternative equivalent parts may be required due to supply chain considerations, end-of-life status of certain variants, or compliance requirements for specific application environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC5025F8251CS is determined by strict adherence to the following parameters:

Critical Parameters (must match exactly):

• Resistance Value: 8.25 kOhms
• Tolerance: ±1%
• Package/Case: 2010 (5025 Metric)
• Operating Temperature Range: -55°C to 155°C
• Temperature Coefficient: ±100ppm/°C
• Composition: Thick Film

Acceptable Variation Parameters:

• Power Rating: Substitute parts may have equal or greater power rating (0.667W minimum)
• RoHS Status: Substitutes must maintain ROHS3 compliance or higher
• Moisture Sensitivity Level: MSL 1 rating required

The RC5025F8251CS has two qualified substitutes that meet these criteria: CRCW20108K25FKEF (Vishay Dale) and ERJ-12SF8251U (Panasonic Electronic Components). Both maintain identical resistance, tolerance, package footprint, and thermal characteristics while offering increased power ratings (0.75W) and automotive-grade qualification (AEC-Q200).

Parameter Comparison

Engineering Selection Recommendations

CRCW20108K25FKEF (Vishay Dale) is the primary substitute for new designs and production applications. This part maintains full ROHS3 compliance, active product status, and introduces automotive-grade AEC-Q200 qualification with increased power rating (0.75W). The higher power rating provides thermal margin in applications approaching the original 0.667W specification limit. Packaging compatibility is verified; the height difference (0.028" vs. 0.026" seated height) falls within standard PCB design tolerances for 2010 package footprints.

ERJ-12SF8251U (Panasonic Electronic Components) is not recommended for new designs due to its "Not For New Designs" product status and RoHS non-compliance. This part may only be considered for legacy system maintenance or applications where RoHS exemptions are documented. The AEC-Q200 automotive qualification and increased power rating remain applicable for existing installations where this component is currently in use.

Frequently Asked Questions (FAQ)

Q: Can CRCW20108K25FKEF be used as a direct replacement for RC5025F8251CS? A: Yes. Both parts share identical resistance value (8.25 kOhms), tolerance (±1%), package footprint (2010/5025 Metric), operating temperature range (-55°C to 155°C), and temperature coefficient (±100ppm/°C). The CRCW20108K25FKEF features increased power rating (0.75W vs. 0.667W), which is compatible with applications designed for the original part. Physical height difference (0.028" vs. 0.026") does not affect PCB assembly or component clearance in standard 2010 package implementations.

Q: Why does CRCW20108K25FKEF have a higher power rating than the original? A: The increased power rating (0.75W vs. 0.667W) reflects manufacturing process differences between manufacturers and does not alter electrical specifications. Both parts dissipate identical power at equivalent current loads. The higher rating provides additional thermal operating margin without affecting resistive or frequency response characteristics.

Q: Is ERJ-12SF8251U suitable for new product designs? A: No. The ERJ-12SF8251U carries "Not For New Designs" status and does not meet ROHS3 compliance requirements. This component is restricted to replacement and maintenance applications only. CRCW20108K25FKEF is the appropriate selection for new designs and production implementations.

Q: What is the difference between the 2010 package dimensions across these parts? A: All three parts conform to the 2010 (5025 Metric) package standard with identical length (0.197"/5.00mm) and width (0.098"/2.50mm). Seated height varies slightly: RC5025F8251CS maximum 0.026" (0.66mm), while CRCW20108K25FKEF and ERJ-12SF8251U maximum 0.028" (0.70mm). This variance is within standard PCB design clearance specifications for surface mount assemblies.

Q: Are these parts suitable for automotive applications? A: CRCW20108K25FKEF and ERJ-12SF8251U both carry AEC-Q200 automotive qualification, making them suitable for automotive environment requirements. RC5025F8251CS lacks automotive-specific certification but operates across the same temperature range. Application requirements should dictate whether AEC-Q200 qualification is necessary.
