RC5025F6812CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F6812CS is a 68.1 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 and features moisture-resistant construction suitable for general industrial applications.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint. The primary drivers for component substitution include inventory availability, supply chain continuity, and application-specific certifications such as automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F6812CS is determined by strict adherence to the following criteria:

Mandatory Matching Parameters:

• Resistance value: 68.1 kOhms
• Tolerance: ±1%
• Package / Case: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Power Rating: Substitute parts rated at 0.75W (3/4W) or higher are acceptable, as they provide equal or greater power dissipation capability within the same package footprint.

All identified substitute parts meet these criteria and maintain full electrical and mechanical compatibility with the original RC5025F6812CS specification.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status): The CRCW201068K1FKEF manufactured by Vishay Dale is the recommended substitute for new designs and ongoing production. This part maintains Active product status, ensuring long-term availability and supply chain stability. The higher power rating of 0.75W provides additional thermal margin compared to the original 0.667W specification. AEC-Q200 automotive qualification provides enhanced reliability documentation suitable for demanding applications.

Secondary Selection (Legacy Applications): The ERJ-12SF6812U manufactured by Panasonic Electronic Components is classified as Not For New Designs. This designation indicates the part remains available for existing applications but should not be selected for new circuit designs. The part carries identical electrical specifications and AEC-Q200 automotive qualification. Selection of this part is appropriate only when maintaining compatibility with existing production runs or legacy equipment.

Compliance Considerations: All three parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with modern manufacturing processes and storage requirements without moisture baking procedures.

Frequently Asked Questions (FAQ)

Q: Can the CRCW201068K1FKEF replace the RC5025F6812CS in existing designs?

A: Yes. The CRCW201068K1FKEF provides identical electrical performance with matching resistance, tolerance, temperature coefficient, and operating temperature range. The increased power rating (0.75W versus 0.667W) is a non-limiting parameter that provides additional thermal capability. Both parts use identical 2010 (5025 Metric) package dimensions and footprints.

Q: What is the significance of the "Not For New Designs" status on the ERJ-12SF6812U?

A: This designation indicates that Panasonic has discontinued active development and promotion of this part number for new applications. While the part remains electrically and mechanically compatible, it should be used only for sustaining production of existing designs. New circuit designs should specify either the RC5025F6812CS or CRCW201068K1FKEF.

Q: Are there differences in package dimensions between these parts?

A: No. All three parts conform to the 2010 (5025 Metric) package specification with identical length (0.197" / 5.00mm) and width (0.098" / 2.50mm). Maximum seated heights are 0.026" (0.66mm) for the RC5025F6812CS and 0.028" (0.70mm) for both substitute parts. These minor height variations remain within standard PCB assembly tolerances and do not affect interchangeability.

Q: What does AEC-Q200 qualification mean for the substitute parts?

A: AEC-Q200 is an automotive industry standard qualification that certifies component reliability under automotive operating conditions. Both CRCW201068K1FKEF and ERJ-12SF6812U carry this certification, indicating enhanced testing and documentation. The original RC5025F6812CS does not specify AEC-Q200 qualification. Selection of AEC-Q200 qualified parts is required for automotive applications.

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

A: Yes. All three parts share identical electrical specifications (68.1 kOhms ±1%, ±100ppm/°C, -55°C ~ 155°C operating range) and package footprints (2010 / 5025 Metric). PCB layouts designed for any one of these parts accommodate the others without modification. Solder reflow profiles and assembly processes remain unchanged.

Q: What inventory considerations apply to these substitutes?

A: The RC5025F6812CS has 1057 pieces in stock, CRCW201068K1FKEF has 6830 pieces, and ERJ-12SF6812U has 10520 pieces available. For applications requiring immediate delivery or high-volume procurement, the substitute parts offer significantly higher inventory levels.
