Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F6492CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value (64.9 kOhms), tolerance (±1%), power rating (0.125W), and temperature coefficient (±100ppm/°C) must be identical.

Mechanical Parameters: Package designation (0805 / 2012 Metric), physical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm), and termination count (2) must match.

Environmental & Compliance Parameters: Operating temperature range (-55°C ~ 155°C), Moisture Sensitivity Level (MSL 1), RoHS3 compliance, and REACH unaffected status must be maintained.

Composition: Thick film construction is required for all substitutes.

All identified substitute parts meet these criteria. Additional features such as Automotive AEC-Q200 qualification or moisture resistant designation represent enhanced capabilities that do not preclude substitution but indicate expanded application scope.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts are Active product status and maintain full ROHS3 compliance and REACH unaffected designation, ensuring regulatory alignment with the original RC2012F6492CS component.

For general industrial applications: CR0805-FX-6492ELF (Bourns), RC0805FR-0764K9L (YAGEO), and the original RC2012F6492CS (Samsung Electro-Mechanics) provide moisture resistant construction suitable for standard PCB environments.

For automotive and high-reliability applications: ERJ-6ENF6492V (Panasonic), RMCF0805FT64K9 (Stackpole), and CRCW080564K9FKEA (Vishay Dale) carry Automotive AEC-Q200 qualification, indicating enhanced screening and reliability validation for automotive-grade circuit designs.

For space-constrained layouts: CRCW080564K9FKEA (Vishay Dale) offers the lowest seated height at 0.50mm maximum, compared to 0.65mm for the original part, providing potential PCB assembly advantages in high-density designs.

All substitutes maintain identical electrical performance and operating temperature range, ensuring direct functional equivalence in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can CRCW080564K9FKEA replace RC2012F6492CS in any application?

A: Yes. Both components share identical electrical specifications (64.9 kΩ ±1%, 0.125W, ±100ppm/°C), mechanical package (0805), and environmental ratings (MSL 1, -55°C ~ 155°C, ROHS3). The lower seated height (0.50mm vs 0.65mm) of the Vishay part is a dimensional advantage with no functional impact.

Q: What is the difference between moisture resistant and AEC-Q200 qualified parts?

A: Moisture resistant designation indicates construction designed to withstand humidity exposure. AEC-Q200 qualification represents automotive-grade validation including extended environmental testing, failure rate analysis, and manufacturing process controls. Both are compatible substitutes; AEC-Q200 parts provide additional assurance for automotive and mission-critical applications.

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

A: Yes. All listed substitute parts are supplied in Tape & Reel packaging, maintaining consistency with the original RC2012F6492CS packaging format for automated assembly processes.

Q: Do height differences between substitute parts affect PCB assembly?

A: Height variations (0.50mm to 0.70mm maximum seated height) are within standard 0805 package tolerance and do not affect reflow soldering, wave soldering, or automated pick-and-place assembly. Component height is not a limiting factor for substitution in standard PCB designs.

Q: Which substitute offers the highest inventory availability?

A: ERJ-6ENF6492V (Panasonic) provides 65,923 pieces in stock, followed by CR0805-FX-6492ELF (Bourns) with 20,663 pieces and CRCW080564K9FKEA (Vishay Dale) with 14,620 pieces, compared to 642 pieces for the original RC2012F6492CS.

Q: Can automotive-qualified parts be used in non-automotive applications?

A: Yes. Automotive AEC-Q200 qualified parts (ERJ-6ENF6492V, RMCF0805FT64K9, CRCW080564K9FKEA) exceed standard industrial requirements and are fully compatible with general-purpose applications. Enhanced qualification does not restrict use in non-automotive circuits.
