RUT2012FR470CS Equivalent & Substitute Parts

Part Overview

The RUT2012FR470CS is a 470 mOhms ±1% 0.25W thick film chip resistor in 0805 (2012 Metric) package manufactured by Samsung Electro-Mechanics. This component is designed for current sensing applications requiring moisture resistance and operates across the temperature range of -55°C to 155°C. The part maintains Active product status and is RoHS3 compliant with MSL Level 1 rating.

Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and compliance certifications align with the original component, enabling direct replacement in circuit designs without functional compromise.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RUT2012FR470CS is determined by strict alignment of the following parameters:

Electrical Specifications: Resistance value (470 mOhms), tolerance (±1%), power rating (0.25W), and temperature coefficient (±150ppm/°C) must match exactly.

Mechanical Compatibility: Package designation (0805/2012 Metric), physical dimensions (0.079" L x 0.049" W), and termination count (2) must be identical to ensure PCB footprint compatibility.

Compliance Requirements: RoHS3 compliance and MSL Level 1 rating are mandatory for direct substitution in regulated applications.

Composition: Thick film construction is required to maintain performance characteristics in current sensing applications.

The ERJ-U6QFR47V from Panasonic Electronic Components satisfies all substitution criteria, with identical electrical and mechanical specifications. The substitute part introduces additional automotive-grade qualification (AEC-Q200) and anti-sulfur features, which represent enhanced capabilities rather than deviations from the original specification.

Parameter Comparison

Engineering Selection Recommendations

Both the RUT2012FR470CS and ERJ-U6QFR47V are Active status components meeting ROHS3 compliance and MSL Level 1 requirements. Selection between these parts should be based on supply chain availability and application-specific requirements.

The ERJ-U6QFR47V includes AEC-Q200 automotive qualification and anti-sulfur features, making it suitable for automotive and harsh environment applications. The RUT2012FR470CS is specified for general current sensing applications with moisture resistance.

Both components are electrically and mechanically interchangeable within the specified parameters. The maximum seated height difference (0.024" versus 0.026") is within typical PCB assembly tolerances and does not affect functionality.

Frequently Asked Questions (FAQ)

Q: Can ERJ-U6QFR47V replace RUT2012FR470CS in production designs?

A: Yes. Both parts share identical electrical specifications (470 mOhms ±1%, 0.25W), mechanical dimensions (0805 package), temperature coefficient (±150ppm/°C), and compliance ratings (ROHS3, MSL 1). The 0.002" height difference is within standard PCB assembly tolerances.

Q: What is the significance of AEC-Q200 qualification on the substitute part?

A: AEC-Q200 is an automotive industry standard qualification. The ERJ-U6QFR47V meets this standard, indicating enhanced reliability testing and suitability for automotive applications. This does not affect compatibility with non-automotive designs.

Q: Are the physical dimensions truly identical?

A: Both parts conform to the 0805 (2012 Metric) package standard with dimensions of 0.079" L x 0.049" W. The seated height differs by 0.002" (0.61mm versus 0.65mm), which is within typical component tolerance ranges and does not impact PCB footprint compatibility.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both RUT2012FR470CS and ERJ-U6QFR47V carry MSL Level 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: What is the difference between "Current Sense" and "Anti-Sulfur" features?

A: Current Sense indicates the part is optimized for low-resistance applications measuring electrical current. Anti-Sulfur is a material feature providing protection against sulfur-containing atmospheric corrosion, common in automotive and industrial environments. Both features are compatible with the same electrical function.
