RC2012F4534CS Equivalent & Substitute Parts

Part Overview

The RC2012F4534CS is a 4.53 MOhm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 0805 (2012 Metric) package format. This component is rated for 0.125W (1/8W) power dissipation and operates across a temperature range of -55°C to 155°C. The part is classified as Active product status with ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited). Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part becomes unavailable or when design requirements necessitate alternative sourcing options.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F4534CS is determined by strict equivalence across the following critical parameters: resistance value (4.53 MOhms), tolerance (±1%), power rating (0.125W), package format (0805 / 2012 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, MSL 1). All identified substitute parts meet these core electrical and mechanical specifications. Variations in physical dimensions (height-seated maximum) and manufacturer-specific series designations do not affect functional interchangeability within the specified parameter constraints. Packaging format remains Tape & Reel (TR) across all alternatives.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RC2012F4534CS (Samsung Electro-Mechanics), RC0805FR-074M53L (YAGEO), and CRCW08054M53FKEA (Vishay Dale)—are classified as Active product status and meet ROHS3 compliance requirements. The RC0805FR-074M53L serves as a direct manufacturer equivalent with identical electrical specifications and MSL 1 rating. The CRCW08054M53FKEA provides an alternative with additional AEC-Q200 automotive qualification, suitable for applications requiring automotive-grade reliability standards. Physical height variations (0.66mm, 0.60mm, and 0.50mm respectively) are within typical PCB assembly tolerances for 0805 components and do not impact functional performance. Selection between these parts depends on supply availability, cost considerations, and whether automotive-grade certification is required for the end application.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-074M53L (YAGEO) be used as a direct replacement for RC2012F4534CS (Samsung)?

A: Yes. Both parts share identical electrical specifications: 4.53 MOhms resistance, ±1% tolerance, 0.125W power rating, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Both are packaged in 0805 (2012 Metric) format with Tape & Reel delivery and MSL 1 rating. The height difference (0.60mm vs. 0.66mm) is within standard PCB assembly tolerances.

Q: What is the difference between RC0805FR-074M53L and CRCW08054M53FKEA?

A: Both parts meet the core electrical and mechanical specifications for substitution. The CRCW08054M53FKEA includes AEC-Q200 automotive qualification, making it suitable for automotive applications. The CRCW08054M53FKEA has a lower seated height (0.50mm) compared to RC0805FR-074M53L (0.60mm). All other parameters are equivalent.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RC2012F4534CS, RC0805FR-074M53L, and CRCW08054M53FKEA are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Does package format remain consistent across all substitute parts?

A: Yes. All parts use the 0805 (2012 Metric) package format with Tape & Reel (TR) packaging. Physical dimensions are 0.079" L x 0.049" W (2.00mm x 1.25mm) across all alternatives.

Q: Can CRCW08054M53FKEA be used in non-automotive applications?

A: Yes. CRCW08054M53FKEA meets all electrical and mechanical specifications required for the RC2012F4534CS application. AEC-Q200 certification is an additional qualification that does not restrict use in non-automotive circuits.

Q: What is the temperature coefficient specification and does it vary between parts?

A: All three parts have a temperature coefficient of ±100ppm/°C, ensuring consistent performance across the -55°C to 155°C operating range.
