RC0603F511CS Equivalent & Substitute Parts

Part Overview

The RC0603F511CS is a 510 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 0201 (0603 Metric) package format. This component is rated for 0.05W (1/20W) power dissipation and operates across the temperature range of -55°C to 125°C. The part is classified as Active product status and is RoHS3 compliant with Moisture Sensitivity Level 1 (unlimited shelf life). Substitute parts are identified to provide alternative sourcing options when the primary part number becomes unavailable or when inventory constraints require component alternatives that meet identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC0603F511CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Resistance value: 510 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.05W / 1/20W (exact match required)
• Composition: Thick Film (exact match required)

Mechanical Specifications:

• Package format: 0201 (0603 Metric) (exact match required)
• Physical dimensions: 0.024" L x 0.012" W / 0.60mm x 0.30mm (exact match required)
• Height - Seated (Max): 0.010" / 0.26mm (exact match required)
• Number of terminations: 2 (exact match required)

Compliance & Environmental:

• RoHS3 compliance (required)
• Moisture Sensitivity Level 1 (required)
• REACH Unaffected status (required)

The CRCW0201510RFKED manufactured by Vishay Dale meets all critical electrical and mechanical parameters and is therefore classified as a direct equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the RC0603F511CS and CRCW0201510RFKED are Active product status components with full RoHS3 compliance and REACH Unaffected designation. The parts are electrically and mechanically identical across all critical specifications required for circuit functionality.

The CRCW0201510RFKED offers an extended operating temperature range (-55°C to 155°C versus -55°C to 125°C) and a lower temperature coefficient (±100ppm/°C versus ±250ppm/°C). These enhanced performance characteristics do not restrict substitution and represent equivalent or superior performance in temperature-sensitive applications.

Selection between these parts should be based on availability, lead time, packaging format (Cut Tape versus Tape & Reel), and supplier inventory levels. Both components are suitable for direct substitution in applications requiring 510 Ohm ±1% 0.05W thick film chip resistors in 0201 package format.

Frequently Asked Questions (FAQ)

Q: Can the CRCW0201510RFKED be used as a direct replacement for the RC0603F511CS?

A: Yes. The CRCW0201510RFKED meets all critical electrical and mechanical specifications: 510 Ohm resistance, ±1% tolerance, 0.05W power rating, thick film composition, 0201 package format, and identical physical dimensions. Both parts are RoHS3 compliant with MSL 1 rating.

Q: What is the difference between the operating temperature ranges?

A: The RC0603F511CS operates from -55°C to 125°C, while the CRCW0201510RFKED operates from -55°C to 155°C. The Vishay Dale part supports a wider upper temperature limit. This difference does not prevent substitution; the CRCW0201510RFKED is suitable for all applications within the RC0603F511CS temperature range and extends capability to higher temperatures.

Q: Are there packaging differences between these parts?

A: The RC0603F511CS is supplied in Cut Tape (CT) packaging, while the CRCW0201510RFKED is supplied in Tape & Reel (TR) packaging. Both formats contain identical components; packaging format selection depends on assembly process requirements and volume needs.

Q: What does the temperature coefficient difference mean for circuit performance?

A: The RC0603F511CS has a temperature coefficient of ±250ppm/°C, while the CRCW0201510RFKED has ±100ppm/°C. This means the Vishay Dale part exhibits smaller resistance value changes across temperature variations. For most general-purpose applications, both coefficients are acceptable. Applications requiring tighter resistance stability across temperature ranges benefit from the lower coefficient of the CRCW0201510RFKED.

Q: Are both parts suitable for high-reliability applications?

A: Both parts carry RoHS3 compliance, REACH Unaffected status, and Moisture Sensitivity Level 1 (unlimited shelf life). Both are classified as Active products. These certifications indicate suitability for industrial and commercial applications. Specific high-reliability requirements should be evaluated against application-specific standards.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. The identical 0201 package format, physical dimensions (0.024" L x 0.012" W), and height (0.010" max) ensure mechanical and electrical compatibility on PCBs designed for either part. Assembly equipment settings and pick-and-place parameters remain unchanged.
