RCS2012F8660CS Equivalent & Substitute Parts

Part Overview

The RCS2012F8660CS is a 866 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 active in production and ROHS3 compliant. Equivalent and substitute parts are identified when identical electrical specifications and mechanical compatibility are maintained across different manufacturers while preserving the same package footprint and performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RCS2012F8660CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Resistance value: 866 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)

Mechanical Specifications:

• Package type: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Number of terminations: 2 (exact match required)

Compliance & Environmental:

• RoHS3 compliance (required)
• Moisture Sensitivity Level 1 (required)
• REACH unaffected status (required)

All substitute parts listed below meet these criteria without exception. Substitutes may differ in specific features (such as automotive AEC-Q200 qualification or anti-sulfur properties) but maintain full electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805866RFKEA replace RCS2012F8660CS in any application?

A: Yes. Both parts share identical electrical specifications (866 Ohms ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C operating range) and mechanical compatibility (0805 package, thick film composition, 2 terminations). The CRCW0805866RFKEA includes automotive AEC-Q200 qualification, which does not restrict its use in non-automotive applications.

Q: What is the difference between the anti-sulfur feature of RCS2012F8660CS and the standard versions?

A: The RCS2012F8660CS includes anti-sulfur and moisture-resistant properties as specified features. The substitute parts RC0805FR-07866RL also includes moisture-resistant properties. CRCW0805866RFKEA, ERJ-6ENF8660V, and RMCF0805FT866R do not list anti-sulfur as a specified feature but maintain full electrical and mechanical compatibility. Feature differences do not affect substitution eligibility based on the core electrical and mechanical parameters.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All substitute parts listed are supplied in Tape & Reel (TR) packaging, matching the packaging format of the RCS2012F8660CS.

Q: Do the substitute parts have different physical dimensions that could affect PCB layout?

A: All parts use the 0805 (2012 Metric) package with identical length and width dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm). Height-seated measurements vary slightly: RCS2012F8660CS (0.66mm), CRCW0805866RFKEA (0.50mm), ERJ-6ENF8660V (0.70mm), RC0805FR-07866RL (0.60mm), and RMCF0805FT866R (0.65mm). These minor height variations are within standard 0805 package tolerances and do not affect PCB layout or assembly compatibility.

Q: Which substitute has the best inventory availability?

A: ERJ-6ENF8660V from Panasonic Electronic Components has the highest inventory level at 52,527 pieces.

Q: Are all parts ROHS3 compliant?

A: Yes. All parts listed, including the main part RCS2012F8660CS and all substitutes, are ROHS3 compliant and REACH unaffected.
