Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC0603F151CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value (150 Ohms), tolerance (±1%), and power rating (0.05W) must be identical. These parameters define the functional performance of the resistor in the circuit.

Mechanical Parameters: Package type (0201 / 0603 Metric) and physical dimensions (0.024" L x 0.012" W) must match to ensure PCB footprint compatibility and assembly process compatibility.

Environmental & Compliance Parameters: Operating temperature range (-55°C ~ 125°C), moisture resistance feature, RoHS3 compliance, and MSL rating (1 - Unlimited) must be maintained to ensure reliability and regulatory conformance.

Composition: Thick film construction must be preserved to maintain electrical characteristics and thermal behavior.

The substitute part RC0201FR-07150RL from YAGEO meets all these criteria and is therefore classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The RC0201FR-07150RL from YAGEO is a direct functional and mechanical equivalent to the RC0603F151CS from Samsung Electro-Mechanics. Both components are ROHS3 compliant, carry MSL rating 1 (Unlimited), and are REACH unaffected. Both maintain active product status.

The RC0201FR-07150RL exhibits a lower temperature coefficient (±200ppm/°C versus ±250ppm/°C), which represents improved temperature stability. The seated height specification differs marginally (0.26mm versus 0.25mm), which remains within acceptable PCB assembly tolerances for 0201 package components.

Selection between these parts should be based on availability, lead time, and supply chain requirements, as both components satisfy identical electrical, mechanical, and compliance specifications for the 150 Ohm ±1% 0.05W 0201 chip resistor application.

Frequently Asked Questions (FAQ)

Q: Can RC0201FR-07150RL be used as a direct replacement for RC0603F151CS?

A: Yes. Both components share identical resistance (150 Ohms), tolerance (±1%), power rating (0.05W), package type (0201), physical dimensions, composition (thick film), operating temperature range, and compliance certifications. The components are electrically and mechanically interchangeable.

Q: What is the significance of the different temperature coefficients?

A: The RC0201FR-07150RL has a temperature coefficient of ±200ppm/°C compared to ±250ppm/°C for the RC0603F151CS. This means the YAGEO part exhibits slightly better resistance stability across temperature variations. For most applications, both values are acceptable; however, precision circuits may benefit from the lower coefficient.

Q: Are the physical dimensions truly identical?

A: The length and width are identical (0.024" L x 0.012" W / 0.60mm x 0.30mm). The seated height differs by 0.01mm (0.26mm versus 0.25mm), which is negligible for standard PCB assembly processes and does not affect footprint compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both RC0603F151CS and RC0201FR-07150RL are ROHS3 compliant, REACH unaffected, carry MSL rating 1 (Unlimited), and share identical ECCN (EAR99) and HTSUS classifications.

Q: What packaging format is used for both parts?

A: Both components are supplied in Tape & Reel (TR) format, suitable for automated assembly processes.

Q: Can these parts be mixed in the same production batch?

A: Yes. Since both components are electrically and mechanically equivalent with identical package specifications, they can be used interchangeably within the same design and production environment.
