RCS2012F6492CS Equivalent & Substitute Parts

Part Overview

The RCS2012F6492CS is a 64.9 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in 0805 (2012 Metric) package format with 0.125W power rating. This component is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). The RCS2012F6492CS is designed for general-purpose applications requiring precision resistive elements with anti-sulfur and moisture-resistant characteristics. Equivalent and substitute parts are identified to provide design flexibility, supply chain alternatives, and component availability options for applications where the primary part number may be unavailable or where specific performance certifications are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F6492CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 64.9 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3
• Moisture sensitivity level: 1 (Unlimited)
• Termination count: 2

All identified substitute parts meet these mandatory parameters. Substitute parts are grouped by manufacturer and series designation while maintaining complete electrical and mechanical equivalence. Dimensional variations in seated height are within acceptable tolerances for 0805 package specifications and do not affect functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts are functionally equivalent to the RCS2012F6492CS based on electrical specifications, mechanical dimensions, and compliance certifications. Selection among these alternatives is determined by application-specific requirements and supply chain considerations:

CRCW080564K9FKEA (Vishay Dale): This substitute carries AEC-Q200 automotive qualification. Selection is appropriate for applications requiring automotive-grade component certification. Inventory availability is 14,620 units.

ERJ-6ENF6492V (Panasonic Electronic Components): This substitute carries AEC-Q200 automotive qualification. Selection is appropriate for automotive applications. Inventory availability is 65,923 units, representing the highest stock level among all alternatives.

RC0805FR-0764K9L (YAGEO): This substitute features moisture-resistant characteristics aligned with the primary part. Selection is appropriate for general-purpose applications without automotive requirements. Inventory availability is 5,300 units.

RMCF0805FT64K9 (Stackpole Electronics Inc): This substitute carries AEC-Q200 automotive qualification. Selection is appropriate for automotive applications. Inventory availability is 1,417 units.

All substitute parts maintain ROHS3 compliance, unlimited MSL rating, and identical electrical performance specifications. Seated height variations are within acceptable tolerances for 0805 package specifications and do not affect PCB assembly compatibility or functional performance.

Frequently Asked Questions (FAQ)

Q: Can CRCW080564K9FKEA replace RCS2012F6492CS in non-automotive applications?

A: Yes. CRCW080564K9FKEA meets all electrical and mechanical specifications required for direct substitution. The AEC-Q200 automotive qualification is an additional feature that does not restrict use in non-automotive applications.

Q: What is the significance of AEC-Q200 rating on substitute parts?

A: AEC-Q200 is an automotive industry qualification standard. Substitute parts carrying this rating (CRCW080564K9FKEA, ERJ-6ENF6492V, RMCF0805FT64K9) are qualified for automotive applications. This certification is not required for general-purpose applications but indicates additional quality and reliability testing.

Q: Are there differences in seated height among substitute parts?

A: Seated height varies between 0.020" (0.50mm) and 0.028" (0.70mm) across all parts. These variations are within standard 0805 package tolerances and do not affect PCB assembly compatibility or electrical performance.

Q: Is the RCS2012F6492CS anti-sulfur feature replicated in all substitutes?

A: The primary part specifies anti-sulfur and moisture-resistant characteristics. RC0805FR-0764K9L explicitly lists moisture-resistant features. CRCW080564K9FKEA, ERJ-6ENF6492V, and RMCF0805FT64K9 do not explicitly specify anti-sulfur treatment in the provided data. For applications requiring confirmed anti-sulfur protection, RC0805FR-0764K9L or the primary part RCS2012F6492CS are recommended.

Q: Can substitute parts be used interchangeably on the same PCB assembly?

A: Yes. All substitute parts are mechanically and electrically equivalent within the 0805 package specification. They are suitable for direct substitution in PCB designs without layout modifications.

Q: Which substitute part has the highest inventory availability?

A: ERJ-6ENF6492V (Panasonic Electronic Components) has the highest inventory availability at 65,923 units.
