RUT2012FR750CS Equivalent & Substitute Parts

Part Overview

The RUT2012FR750CS is a 750 mOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated for 0.25W (1/4W) power dissipation in the 0805 (2012 Metric) package. This component is designed for current sense applications with moisture-resistant characteristics 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 (Unlimited moisture sensitivity).

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 degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RUT2012FR750CS is determined by strict alignment of the following parameters:

Critical Electrical Parameters:

• Resistance value: 750 mOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±150ppm/°C
• Operating temperature range: -55°C to 155°C

Critical Mechanical Parameters:

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

Compliance Requirements:

• RoHS3 compliance
• MSL Level 1 (Unlimited)
• Thick film composition

The ERJ-U6QFR75V from Panasonic Electronic Components satisfies all critical parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the RUT2012FR750CS and ERJ-U6QFR75V maintain Active product status and satisfy RoHS3 compliance requirements. The ERJ-U6QFR75V incorporates additional features including anti-sulfur protection and AEC-Q200 automotive qualification, which provide enhanced reliability in demanding environments without compromising compatibility with the original design.

The maximum seated height differential of 0.002" (0.04mm) between the two components falls within standard PCB assembly tolerances and does not impact circuit performance or board layout constraints for 0805 package applications.

Selection between these components should be based on application-specific requirements: the RUT2012FR750CS for general current sense applications, and the ERJ-U6QFR75V for automotive or high-reliability applications requiring AEC-Q200 qualification.

Frequently Asked Questions (FAQ)

Q: Can ERJ-U6QFR75V replace RUT2012FR750CS in existing designs?

A: Yes. Both components share identical electrical specifications (750 mOhms ±1%, 0.25W, ±150ppm/°C), operate across the same temperature range (-55°C to 155°C), and are packaged in the 0805 (2012 Metric) form factor with matching footprints. RoHS3 and MSL Level 1 compliance are equivalent.

Q: What is the significance of the height difference between these parts?

A: The RUT2012FR750CS has a maximum seated height of 0.024" (0.61mm), while the ERJ-U6QFR75V measures 0.026" (0.65mm). This 0.002" (0.04mm) difference is within standard PCB assembly process tolerances and does not affect circuit board design or component placement.

Q: Are there packaging differences between these substitutes?

A: Both components are supplied in Tape & Reel (TR) packaging format, standard for 0805 package resistors in production environments. Reel specifications and tape dimensions follow industry standards for this package type.

Q: What additional certifications does the ERJ-U6QFR75V provide?

A: The ERJ-U6QFR75V includes AEC-Q200 automotive qualification and anti-sulfur protection. These features enhance reliability in automotive and harsh environment applications while maintaining full compatibility with the RUT2012FR750CS electrical and mechanical specifications.

Q: How do the tolerance and temperature coefficient specifications compare?

A: Both components specify ±1% tolerance and ±150ppm/°C temperature coefficient, ensuring equivalent performance stability across the operating temperature range of -55°C to 155°C.
