RCS2012F561CS Equivalent & Substitute Parts Reference

Part Overview

The RCS2012F561CS is a 560 Ohms ±1% 0.125W (1/8W) chip resistor manufactured by Samsung Electro-Mechanics in the 0805 (2012 Metric) package. This thick film resistor features anti-sulfur and moisture-resistant properties, with an operating temperature range of -55°C to 155°C. The part is currently in active production status with 906 pieces in stock inventory.

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design requirements necessitate alternative sourcing. Substitute parts must maintain identical electrical specifications (resistance value, tolerance, power rating) and mechanical compatibility (package size, termination count) to ensure direct board-level replacement without circuit redesign.

Engineering Selection Recommendations

For Direct Replacement (0.125W / 1/8W Category):

CRCW0805560RFKEA, ERJ-6ENF5600V, RC0805FR-07560RL, and RMCF0805FT560R are electrically and mechanically equivalent to the RCS2012F561CS. All maintain identical resistance, tolerance, power rating, and package specifications. Selection among these direct equivalents may be based on:

Inventory availability and lead time
Packaging format preference (Tape & Reel vs. Cut Tape & Digi-Reel)
Automotive qualification requirements (AEC-Q200 rated options: CRCW0805560RFKEA, ERJ-6ENF5600V, RMCF0805FT560R)
Height constraints in PCB assembly (CRCW0805560RFKEA and RCS0805560RFKEA offer 0.50mm maximum height)

For Higher Power Applications (0.5W / 1/2W Category):

CRCW0805560RFKEAHP, ERJ-UP6F5600V, and RCS0805560RFKEA provide increased power dissipation capability (0.5W vs. 0.125W) while maintaining all other electrical and mechanical specifications. These parts are suitable for circuits where the original 0.125W rating is insufficient. All three options carry AEC-Q200 automotive qualification and pulse-withstanding capability.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and MSL 1 (unlimited moisture sensitivity level) status, ensuring compatibility with standard PCB assembly and storage procedures. No additional handling or environmental controls are required beyond standard industry practices.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805560RFKEAHP (0.5W) be used as a direct replacement for RCS2012F561CS (0.125W)?

A: Yes. The 0.5W part is mechanically and electrically compatible. The higher power rating provides additional thermal margin and does not negatively affect circuit operation. The part occupies the same PCB footprint (0805) and maintains identical resistance, tolerance, and temperature characteristics. Selection of the higher power rating is acceptable for direct substitution.

Q: What is the difference between the 0.125W and 0.5W versions?

A: The primary difference is power dissipation capability. Both versions share identical resistance (560 Ohms), tolerance (±1%), package size (0805), and operating temperature range (-55°C to 155°C). The 0.5W versions (CRCW0805560RFKEAHP, ERJ-UP6F5600V, RCS0805560RFKEA) are designed for applications requiring higher current handling or continuous power dissipation. The 0.125W versions are suitable for standard signal-level applications.

Q: Are all substitute parts AEC-Q200 qualified?

A: No. Direct equivalents CRCW0805560RFKEA, ERJ-6ENF5600V, and RMCF0805FT560R carry AEC-Q200 automotive qualification. RC0805FR-07560RL (YAGEO) does not list AEC-Q200 qualification. The original RCS2012F561CS does not specify AEC-Q200 rating. For automotive applications requiring AEC-Q200 compliance, select from the qualified options.

Q: Do height differences affect PCB assembly compatibility?

A: Height variations (0.50mm to 0.70mm maximum seated height) are within standard 0805 package tolerances and do not affect PCB assembly compatibility. All parts use identical 0805 footprints. Height differences may be relevant only in space-constrained applications with specific clearance requirements above the PCB surface.

Q: Can I mix different substitute parts on the same PCB?

A: Yes. All substitute parts are electrically and mechanically equivalent and can be used interchangeably on the same board. Mixing different manufacturers or power ratings does not create compatibility issues, as all parts meet the same electrical specifications and package requirements.

Q: What packaging formats are available?

A: Substitute parts are supplied in two packaging formats: Tape & Reel (TR) for automated assembly and Cut Tape (CT) & Digi-Reel for manual or mixed-volume applications. RC0805FR-07560RL is the only option available in Cut Tape format. All other substitutes are supplied in Tape & Reel format.

Q: Are all parts ROHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance status, ensuring compatibility with environmental regulations and standard PCB assembly processes. No additional material certifications or handling procedures are required.
