RUT2012FR620CS Equivalent & Substitute Parts

Part Overview

The RUT2012FR620CS is a 620 mOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated for 0.25W (1/4W) power dissipation in a 0805 (2012 Metric) surface mount package. 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 with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified when alternative manufacturers offer components with identical or functionally equivalent electrical specifications, mechanical dimensions, and environmental ratings. Substitution becomes necessary due to supply chain availability, inventory levels, or procurement preferences while maintaining design integrity and performance requirements.

Substitute Part Grouping Explanation

Substitution of the RUT2012FR620CS is based on strict equivalence across the following critical parameters:

Electrical Equivalence:

• Resistance value: 620 mOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±150ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Equivalence:

• Package designation: 0805 (2012 Metric)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Number of terminations: 2

Compliance Equivalence:

• RoHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)
• REACH unaffected status

The ERJ-U6QFR62V from Panasonic Electronic Components meets all electrical and mechanical equivalence criteria. While the Panasonic part includes additional features (Anti-Sulfur coating and AEC-Q200 automotive qualification), these represent enhanced capabilities that do not preclude substitution in applications requiring the base specifications of the Samsung part.

Parameter Comparison

Engineering Selection Recommendations

Both the RUT2012FR620CS and ERJ-U6QFR62V maintain Active product status and satisfy ROHS3 compliance requirements. The components are electrically and mechanically equivalent across all specified parameters including resistance value, tolerance, power rating, temperature coefficient, and operating temperature range.

The ERJ-U6QFR62V includes AEC-Q200 automotive qualification and Anti-Sulfur coating features. These additional certifications and protective characteristics do not compromise compatibility with applications designed for the base Samsung specification and may provide enhanced reliability in demanding environments.

Selection between these parts should be based on procurement availability, inventory levels, cost considerations, and any application-specific requirements for automotive qualification or enhanced environmental protection. Both parts are suitable for current sensing applications requiring moisture resistance in the 0805 package format.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-U6QFR62V replace the RUT2012FR620CS in existing designs?

A: Yes. The ERJ-U6QFR62V is electrically and mechanically equivalent to the RUT2012FR620CS. Both components share identical resistance values (620 mOhms), tolerance (±1%), power rating (0.25W), temperature coefficient (±150ppm/°C), operating temperature range (-55°C to 155°C), and 0805 package dimensions. The maximum seated height difference (0.024" versus 0.026") is within typical PCB assembly tolerances.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer origin and additional features. The ERJ-U6QFR62V includes Anti-Sulfur coating and AEC-Q200 automotive qualification, which the RUT2012FR620CS does not specify. These represent enhanced capabilities rather than deviations from the base electrical specification.

Q: Are both parts RoHS compliant?

A: Yes. Both the RUT2012FR620CS and ERJ-U6QFR62V are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the moisture sensitivity level for these components?

A: Both parts carry Moisture Sensitivity Level 1 (MSL 1), indicating unlimited shelf life without special moisture control measures during storage and handling.

Q: Are there any package or footprint compatibility concerns?

A: No. Both components use the 0805 (2012 Metric) package with identical length and width dimensions (0.079" x 0.049" or 2.00mm x 1.25mm). The maximum seated height difference of 0.002" (0.04mm) is negligible for standard PCB assembly processes.

Q: Can these parts be used in current sensing applications?

A: Yes. Both components are specified for current sensing applications. The RUT2012FR620CS explicitly includes current sensing as a feature, and the ERJ-U6QFR62V maintains equivalent electrical characteristics suitable for this application class.
