RCS2012F6342CS Equivalent & Substitute Parts

Part Overview

The RCS2012F6342CS is a 63.4 kOhms ±1% 0.125W (1/8W) chip resistor in 0805 (2012 Metric) package manufactured by Samsung Electro-Mechanics. 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 active and ROHS3 compliant. Alternative equivalent parts are necessary to ensure supply chain continuity, leverage manufacturer-specific certifications (such as automotive AEC-Q200 ratings), or accommodate different packaging formats (tape & reel versus cut tape).

Key Parameters

Substitute Part Grouping Explanation

Substitution for the RCS2012F6342CS is determined by strict equivalence of electrical and mechanical parameters. All substitute parts must meet the following criteria:

• Resistance Value: 63.4 kOhms (exact match)
• Tolerance: ±1% (exact match)
• Power Rating: 0.125W (1/8W) (exact match)
• Package: 0805 (2012 Metric) (exact match)
• Temperature Coefficient: ±100ppm/°C (exact match)
• Operating Temperature: -55°C ~ 155°C (exact match)
• Composition: Thick Film (exact match)
• RoHS Compliance: ROHS3 Compliant (exact match)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match)

Variations in product features (such as anti-sulfur coating, automotive AEC-Q200 certification, or packaging format) do not prevent substitution provided all core electrical and mechanical parameters remain equivalent. Physical dimensions (length, width, and height) are functionally equivalent within tolerances specified for 0805 package devices.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed—RC2012F6342CS, CRCW080563K4FKEA, ERJ-6ENF6342V, RC0805FR-0763K4L, and RMCF0805FT63K4—are active products meeting ROHS3 compliance and maintaining full electrical and mechanical equivalence to the RCS2012F6342CS.

RC2012F6342CS (Samsung Electro-Mechanics) differs only in packaging format (cut tape versus tape & reel) and omits the anti-sulfur feature present in the main part. This variant is directly substitutable.

CRCW080563K4FKEA (Vishay Dale), ERJ-6ENF6342V (Panasonic Electronic Components), and RMCF0805FT63K4 (Stackpole Electronics Inc) carry automotive AEC-Q200 qualification. These parts are suitable for applications requiring automotive-grade reliability certifications in addition to standard industrial requirements.

RC0805FR-0763K4L (YAGEO) is a standard industrial-grade equivalent without automotive certification, suitable for non-automotive applications.

Selection among these equivalents depends on supply availability, packaging requirements (tape & reel or cut tape), and whether automotive AEC-Q200 certification is mandated by application specifications.

Frequently Asked Questions (FAQ)

Can the RC2012F6342CS be substituted with CRCW080563K4FKEA? Yes. Both parts meet identical electrical specifications (63.4 kOhms ±1%, 0.125W, ±100ppm/°C) and are packaged in 0805 (2012 Metric) cases. The CRCW part includes automotive AEC-Q200 certification, which does not prevent substitution in standard industrial applications.

What is the difference between RCS2012F6342CS and RC2012F6342CS? Both are Samsung Electro-Mechanics products with identical electrical and mechanical specifications. The primary differences are packaging format (RCS supplied on tape & reel; RC available in cut tape) and feature set (RCS includes anti-sulfur coating; RC specifies moisture resistance). Core resistive properties remain equivalent.

Are all listed substitute parts suitable for automotive applications? CRCW080563K4FKEA (Vishay Dale), ERJ-6ENF6342V (Panasonic), and RMCF0805FT63K4 (Stackpole) carry AEC-Q200 automotive qualification. RC2012F6342CS (Samsung, cut tape) and RC0805FR-0763K4L (YAGEO) are industrial-grade equivalents suitable for non-automotive applications or applications where automotive certification is not required.

Do these parts meet moisture sensitivity requirements? All listed parts have Moisture Sensitivity Level 1 (Unlimited), indicating unlimited shelf life without special moisture-control packaging requirements.

What is the significance of the 0805 package designation? The 0805 (2012 Metric) package denotes a surface-mount resistor with dimensions of 0.079" length × 0.049" width (2.00mm × 1.25mm). All listed parts conform to this industry-standard package envelope, ensuring mechanical and electrical compatibility in circuit board designs.
