Key Parameters

Substitute Part Grouping Explanation

Substitution of the RCS2012F8663CS is permissible with parts meeting the following criteria:

Mandatory Electrical Parameters:

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

Mandatory Mechanical Parameters:

• Package / Case: 0805 (2012 Metric)
• Composition: Thick Film
• Number of terminations: 2
• Moisture Sensitivity Level: 1 (Unlimited)

Compliance Requirements:

• RoHS3 Compliant
• REACH Unaffected status

All identified substitute parts satisfy these parameters. Variations in physical dimensions (height-seated maximum) and additional certifications (such as AEC-Q200 automotive qualification) do not preclude substitution when the core electrical and mechanical specifications align.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed—RCS2012F8663CS, CRCW0805866KFKEA, ERJ-6ENF8663V, and RC0805FR-07866KL—are Active product status components with full ROHS3 compliance and REACH Unaffected designation. Selection among these parts is determined by availability, supply chain considerations, and application-specific requirements.

CRCW0805866KFKEA (Vishay Dale) and ERJ-6ENF8663V (Panasonic) include AEC-Q200 automotive qualification, which provides additional assurance for applications requiring automotive-grade reliability standards. These parts are suitable for automotive and high-reliability applications.

RC0805FR-07866KL (YAGEO) offers the highest inventory availability and maintains full electrical and mechanical compatibility with the primary part.

RCS2012F8663CS (Samsung) features anti-sulfur construction in addition to moisture resistance, providing enhanced environmental protection in corrosive atmospheres.

All parts are suitable for direct substitution in standard industrial and commercial applications where the core electrical specifications and package requirements are met.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805866KFKEA replace RCS2012F8663CS in any application?

A: Yes. Both parts meet identical electrical specifications (866 kOhms ±1%, 0.125W, ±100ppm/°C, -55°C ~ 155°C operating range) and are packaged in 0805 (2012 Metric) thick film construction. The CRCW0805866KFKEA includes AEC-Q200 automotive qualification, which does not restrict its use in non-automotive applications.

Q: What is the difference between the anti-sulfur feature of RCS2012F8663CS and the standard moisture-resistant construction of other parts?

A: Anti-sulfur construction provides additional protection against sulfur-containing atmospheric contaminants and corrosive environments. Standard moisture-resistant thick film construction protects against humidity and moisture ingress. Selection between these features depends on the specific environmental conditions of the application.

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

A: Yes. All listed parts—RCS2012F8663CS, CRCW0805866KFKEA, ERJ-6ENF8663V, and RC0805FR-07866KL—are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.

Q: Do physical dimension variations affect substitution compatibility?

A: Physical dimensions (height-seated maximum) vary slightly among manufacturers: Samsung 0.66mm, Vishay Dale 0.50mm, Panasonic 0.70mm, and YAGEO 0.60mm. These variations remain within standard 0805 package tolerances and do not affect PCB layout or assembly compatibility. All parts are mechanically interchangeable.

Q: What is Moisture Sensitivity Level (MSL) 1, and why is it important?

A: MSL 1 indicates unlimited shelf life without moisture absorption concerns. All listed parts carry MSL 1 rating, eliminating the need for special storage conditions or baking procedures prior to assembly.

Q: Are these parts suitable for high-temperature applications?

A: Yes. All parts operate across the -55°C ~ 155°C temperature range with ±100ppm/°C temperature coefficient, suitable for industrial and automotive high-temperature environments within these specified limits.
