Engineering Selection Recommendations

Primary Substitutes (Recommended for General Applications):

The following parts are recommended as direct substitutes for the RCS2012F6810CS in standard applications:

• RC2012F6810CS (Samsung Electro-Mechanics): Identical electrical specifications with ROHS3 compliance. Differs only in packaging format (Cut Tape vs. Tape & Reel). Suitable for applications where packaging format flexibility is acceptable.

• CRCW0805681RFKEA (Vishay Dale): Meets all electrical and mechanical requirements with ROHS3 compliance and AEC-Q200 automotive qualification. Compact height profile (0.50mm) suitable for space-constrained designs.

• RC0805FR-07681RL (YAGEO): Fully compliant with ROHS3 and all electrical specifications. High inventory availability (221,715 pcs) ensures supply continuity.

• RMCF0805FT681R (Stackpole Electronics Inc): Meets all specifications with ROHS3 compliance and AEC-Q200 automotive qualification. Largest inventory stock (133,662 pcs) provides supply security.

Conditional Substitute:

• CRCW0805681RFKTA (Vishay Dale): Electrically and mechanically equivalent but marked as RoHS non-compliant and REACH Affected. Use only in applications where RoHS compliance is not required.

Alternative with Extended Features:

• ERJ-6ENF6810V (Panasonic Electronic Components): Meets all specifications with ROHS3 compliance and AEC-Q200 automotive qualification. Available in Cut Tape and Digi-Reel® packaging formats.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC2012F6810CS for RCS2012F6810CS?

A: Yes. Both parts are manufactured by Samsung Electro-Mechanics with identical electrical specifications (681 Ω, ±1%, 0.125W, ±100ppm/°C, -55°C ~ 155°C). The primary difference is packaging format: RCS2012F6810CS is supplied in Tape & Reel (TR) while RC2012F6810CS is supplied in Cut Tape (CT). Both are ROHS3 compliant and functionally interchangeable.

Q: Are automotive-qualified parts (AEC-Q200) suitable replacements?

A: Yes. Parts bearing AEC-Q200 qualification (CRCW0805681RFKEA, CRCW0805681RFKTA, ERJ-6ENF6810V, RMCF0805FT681R) meet or exceed the electrical and mechanical specifications of the RCS2012F6810CS. AEC-Q200 qualification indicates enhanced reliability testing and is acceptable for general-purpose applications.

Q: What is the significance of the height difference between substitute parts?

A: The RCS2012F6810CS has a maximum seated height of 0.66mm. Substitute parts range from 0.50mm to 0.70mm. These variations remain within acceptable tolerances for standard 0805 package designs. Height differences may be relevant only in applications with strict vertical clearance constraints (e.g., stacked component assemblies).

Q: Can I use CRCW0805681RFKTA as a substitute?

A: CRCW0805681RFKTA is electrically and mechanically equivalent but is marked as RoHS non-compliant and REACH Affected. Use this part only if your application does not require RoHS3 compliance or REACH compliance. For new designs or regulated applications, use CRCW0805681RFKEA instead.

Q: Which substitute offers the best supply availability?

A: RC0805FR-07681RL (YAGEO) has the highest inventory stock at 221,715 pcs, followed by RMCF0805FT681R (Stackpole Electronics Inc) at 133,662 pcs. Both ensure supply continuity for high-volume production requirements.

Q: Are all substitutes compatible with the same PCB footprint?

A: Yes. All substitute parts use the 0805 (2012 Metric) package with identical length (0.079" / 2.00mm) and width (0.049" / 1.25mm) dimensions. PCB footprints designed for RCS2012F6810CS accommodate all listed substitutes without modification.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, suitable for automated pick-and-place assembly. Cut Tape (CT) packaging supplies components on cut segments of carrier tape, suitable for manual assembly or lower-volume applications. Both formats contain identical components; the difference is in delivery and handling format only.
