Part Overview

The RC2012F4643CS is a thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 464 kOhms with ±1% tolerance and 0.125W (1/8W) power dissipation in 0805 (2012 Metric) package format. This component is classified as Active product status with moisture-resistant construction and operates across the temperature range of -55°C to 155°C. The RC2012F4643CS is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, making it suitable for general industrial and commercial applications. Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating), mechanical compatibility (package size, dimensions, termination count), and environmental ratings (operating temperature range, RoHS compliance, REACH status).

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F4643CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value must be 464 kOhms, tolerance must be ±1%, and power rating must be 0.125W (1/8W). Temperature coefficient of ±100ppm/°C and operating temperature range of -55°C to 155°C must be maintained.

Mechanical Parameters: Package format must be 0805 (2012 Metric) with physical dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm). Component height when seated must not exceed specifications that would prevent PCB assembly compatibility. Number of terminations must be 2.

Compliance Parameters: All substitute parts must maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 rating. ECCN and HTSUS classifications remain consistent across all qualified substitutes.

Feature Variations: Substitute parts may include additional features such as Automotive AEC-Q200 certification or High Voltage rating, which represent enhanced specifications that do not compromise compatibility with applications designed for the base RC2012F4643CS specification.

Five substitute parts meet these criteria with full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All seven parts listed—the RC2012F4643CS and its six substitutes—maintain identical electrical specifications and mechanical compatibility within the 0805 package format. Selection between these parts is based on product availability, supply chain considerations, and application-specific requirements.

For General Industrial Applications: CR0805-FX-4643ELF (Bourns), RC0805FR-07464KL (YAGEO), and the original RC2012F4643CS (Samsung Electro-Mechanics) are suitable. These parts feature moisture-resistant construction and are available in high inventory quantities.

For Automotive Applications: ERJ-6ENF4643V (Panasonic), KTR10EZPF4643 (Rohm), RMCF0805FT464K (Stackpole), and CRCW0805464KFKEA (Vishay Dale) carry AEC-Q200 automotive qualification. KTR10EZPF4643 includes additional High Voltage rating capability. These parts are appropriate for automotive-grade circuit designs.

For Space-Constrained PCB Layouts: CRCW0805464KFKEA (Vishay Dale) offers the lowest seated height at 0.020" (0.50mm), followed by CR0805-FX-4643ELF and RC0805FR-07464KL at 0.024" (0.60mm). These options provide maximum clearance for multilayer board designs.

All parts are ROHS3 compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing processes and long-term storage without special handling requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RC2012F4643CS with any of the listed parts without circuit redesign?

A: Yes. All listed substitute parts maintain identical electrical parameters (464 kOhms, ±1% tolerance, 0.125W power rating, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range) and mechanical compatibility (0805 package, 2-termination configuration). Direct substitution is electrically and mechanically valid.

Q: What is the difference between moisture-resistant and automotive AEC-Q200 variants?

A: Moisture-resistant variants (CR0805-FX-4643ELF, RC0805FR-07464KL, RC2012F4643CS) are designed for general industrial environments with enhanced protection against humidity. Automotive AEC-Q200 variants (ERJ-6ENF4643V, KTR10EZPF4643, RMCF0805FT464K, CRCW0805464KFKEA) meet automotive industry qualification standards for reliability and performance in vehicle applications. Both types are ROHS3 compliant and suitable for their respective application domains.

Q: Does component height affect PCB assembly compatibility?

A: Component height variations (0.020" to 0.028" seated height) are within standard 0805 package specifications and do not affect PCB assembly compatibility. Height differences are relevant only for applications with extreme space constraints or specific clearance requirements. Standard pick-and-place equipment accommodates all listed variants.

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

A: Yes. All listed parts, including the RC2012F4643CS and all six substitutes, are supplied in Tape & Reel (TR) packaging format suitable for automated assembly processes.

Q: What is MSL 1 (Unlimited) moisture sensitivity rating?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life without special moisture-control storage requirements. These parts do not require dry-pack storage or baking procedures prior to assembly, simplifying inventory management and reducing handling costs.

Q: Can I use KTR10EZPF4643 in non-automotive applications?

A: Yes. KTR10EZPF4643 exceeds the base specification with Automotive AEC-Q200 certification and High Voltage rating. These enhanced qualifications do not restrict use in general industrial applications; the part is fully compatible with any circuit designed for the RC2012F4643CS specification.

Q: How do I verify part compatibility before ordering?

A: Confirm that your application requires 464 kOhms resistance, ±1% tolerance, 0.125W power dissipation, and 0805 package format. All listed parts meet these criteria. If your design specifies automotive-grade components, select from the AEC-Q200 qualified variants. If space constraints exist, prioritize parts with lower seated height specifications.
