RCS2012F8452CS Equivalent & Substitute Parts

Part Overview

The RCS2012F8452CS is a 84.5 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 0805 (2012 Metric) package format. This component is rated for 0.125W (1/8W) power dissipation and operates across the temperature range of -55°C to 155°C. The part features anti-sulfur and moisture-resistant construction with RoHS3 compliance and unlimited moisture sensitivity level (MSL 1). The RCS2012F8452CS maintains active product status with 881 pieces currently in stock.

Equivalent and substitute parts are identified to provide design flexibility, accommodate supply chain variations, and support applications requiring specific certifications such as automotive AEC-Q200 qualification or alternative manufacturer sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RCS2012F8452CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 84.5 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package format: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Number of terminations: 2
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

All identified substitute parts meet these mandatory parameters. Substitute parts are grouped by manufacturer and may include additional certifications such as automotive AEC-Q200 qualification, which does not preclude substitution but indicates enhanced reliability for specific applications. Physical dimensions (length, width, and seated height) vary slightly between manufacturers but remain within the 0805 package specification envelope.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts are active products with RoHS3 compliance and unlimited moisture sensitivity rating, confirming their suitability for direct replacement in applications currently using the RCS2012F8452CS.

For general industrial and consumer applications: The YAGEO RC0805FR-0784K5L offers equivalent performance with moisture-resistant construction and maintains the highest inventory availability at 68,333 pieces.

For automotive applications requiring AEC-Q200 certification: The Vishay Dale CRCW080584K5FKEA, Panasonic ERJ-6ENF8452V, and Stackpole RMCF0805FT84K5 are qualified alternatives. The Panasonic ERJ-6ENF8452V provides the largest inventory buffer at 50,062 pieces.

For supply chain continuity: The Samsung RCS2012F8452CS original part maintains 881 pieces in stock. The YAGEO RC0805FR-0784K5L and Panasonic ERJ-6ENF8452V offer substantial inventory depth for long-term availability.

All substitute parts maintain identical electrical specifications, operating temperature ranges, and package dimensions within the 0805 specification envelope. Selection between alternatives is determined by application requirements (automotive certification), inventory availability, and preferred supplier relationships.

Frequently Asked Questions (FAQ)

Q: Can the CRCW080584K5FKEA replace the RCS2012F8452CS in non-automotive applications?

A: Yes. The CRCW080584K5FKEA meets all mandatory electrical and mechanical parameters required for substitution. AEC-Q200 certification indicates automotive-grade reliability but does not restrict use in other applications.

Q: What is the significance of the different seated heights among substitute parts?

A: Seated heights range from 0.020" (0.50mm) for the Vishay CRCW080584K5FKEA to 0.028" (0.70mm) for the Panasonic ERJ-6ENF8452V. All values remain within the 0805 package specification. Height variation does not affect electrical performance and is acceptable for standard PCB assembly processes. Applications with height-constrained layouts should reference specific component datasheets.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts carry RoHS3 compliance certification, matching the original RCS2012F8452CS specification.

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

A: MSL 1 indicates the component is not moisture-sensitive and requires no special handling, storage, or baking procedures prior to soldering. All substitute parts carry identical MSL 1 ratings.

Q: Can I use the ERJ-6ENF8452V in place of the RCS2012F8452CS without circuit redesign?

A: Yes. The ERJ-6ENF8452V is a direct electrical and mechanical equivalent. Identical resistance, tolerance, power rating, temperature coefficient, and operating temperature range ensure drop-in compatibility without circuit modification.

Q: Which substitute part offers the best inventory availability?

A: The YAGEO RC0805FR-0784K5L maintains the highest inventory level at 68,333 pieces, followed by the Panasonic ERJ-6ENF8452V at 50,062 pieces.

Q: Do all substitute parts use thick film composition?

A: Yes. All substitute parts employ thick film resistor technology, matching the RCS2012F8452CS composition and ensuring consistent performance characteristics.
