RUT2012JR620CS Equivalent & Substitute Parts

Part Overview

The RUT2012JR620CS is a 620 mOhms ±5% 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 sensing applications with moisture-resistant characteristics. The part maintains Active product status with 772 units in current inventory stock.

Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and package compatibility align with the main part's functional requirements. Substitution becomes necessary when primary component availability is limited or when design requirements permit tolerance or feature variations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RUT2012JR620CS are qualified based on the following criteria:

Electrical Compatibility:

• Identical resistance value: 620 mOhms
• Tolerance equal to or tighter than ±5%
• Identical power rating: 0.25W (1/4W)
• Matching temperature coefficient: ±150ppm/°C
• Overlapping or identical operating temperature range: -55°C ~ 155°C

Mechanical Compatibility:

• Identical package designation: 0805 (2012 Metric)
• Identical physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Compatible termination count: 2 terminations

Compliance & Environmental:

• ROHS3 Compliant status
• Moisture Sensitivity Level 1 (Unlimited)
• REACH Unaffected status
• Identical ECCN and HTSUS classifications

Substitute parts may include enhanced features (such as automotive AEC-Q200 qualification or anti-sulfur properties) without compromising base functionality. Tighter tolerance specifications do not disqualify a substitute part.

Parameter Comparison

Engineering Selection Recommendations

RUT2012JR620CS (Primary Part): The Samsung Electro-Mechanics RUT2012JR620CS remains the specified component with moisture-resistant thick film construction and current sensing optimization. This part is Active in production status with established supply availability.

ERJ-U6QJR62V (Direct Tolerance Match): The Panasonic ERJ-U6QJR62V provides electrical and mechanical equivalence with identical ±5% tolerance specification. This substitute maintains all core electrical parameters while adding automotive AEC-Q200 qualification and anti-sulfur properties. Height variation (0.026" vs. 0.024" maximum seated height) remains within typical PCB assembly tolerances for 0805 packages. This part is suitable for direct substitution in applications where enhanced automotive-grade reliability is acceptable.

ERJ-U6QFR62V (Tighter Tolerance Option): The Panasonic ERJ-U6QFR62V offers ±1% tolerance specification, providing superior resistance accuracy compared to the ±5% main part. This substitute is electrically and mechanically compatible with identical package dimensions and thermal characteristics. The tighter tolerance does not create incompatibility; it represents an enhanced specification. This part is suitable for applications requiring improved resistance accuracy while maintaining all other functional requirements. Automotive AEC-Q200 qualification and anti-sulfur properties are included.

All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and Moisture Sensitivity Level 1 (Unlimited) classification, ensuring regulatory and environmental compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can ERJ-U6QFR62V or ERJ-U6QJR62V be used as direct replacements for RUT2012JR620CS?

A: Yes. Both Panasonic parts meet the electrical and mechanical requirements for substitution. They share identical resistance values (620 mOhms), power ratings (0.25W), package designations (0805), temperature coefficients (±150ppm/°C), and operating temperature ranges (-55°C ~ 155°C). All three parts are ROHS3 compliant with MSL 1 (Unlimited) ratings.

Q: What is the difference between ERJ-U6QFR62V and ERJ-U6QJR62V?

A: The primary difference is tolerance specification. ERJ-U6QFR62V provides ±1% tolerance, while ERJ-U6QJR62V provides ±5% tolerance. Both parts are otherwise electrically and mechanically identical. Selection depends on application requirements for resistance accuracy. The ±1% tolerance part (ERJ-U6QFR62V) is suitable for precision current sensing applications; the ±5% tolerance part (ERJ-U6QJR62V) matches the original specification.

Q: Are there physical dimension differences between these parts?

A: The length and width dimensions are identical across all three parts (0.079" L x 0.049" W / 2.00mm x 1.25mm). Maximum seated height differs slightly: RUT2012JR620CS is 0.024" (0.61mm), while both Panasonic parts are 0.026" (0.65mm). This 0.002" (0.04mm) difference is within standard PCB assembly tolerances for 0805 packages and does not affect board-level compatibility.

Q: Do the substitute parts include additional features?

A: Yes. Both Panasonic ERJ-U6Q series parts include automotive AEC-Q200 qualification and anti-sulfur properties. The Samsung RUT2012JR620CS emphasizes moisture-resistant and current sensing characteristics. These feature differences do not create incompatibility; they represent design enhancements available in the substitute options.

Q: What compliance certifications apply to all three parts?

A: All three parts are ROHS3 compliant, REACH Unaffected, and classified as MSL 1 (Unlimited) for moisture sensitivity. ECCN and HTSUS classifications are identical across all parts (EAR99 and 8533.21.0030 respectively).

Q: Which part should be selected for automotive applications?

A: Both Panasonic substitute parts (ERJ-U6QFR62V and ERJ-U6QJR62V) carry AEC-Q200 automotive qualification. Selection between them depends on tolerance requirements: ERJ-U6QFR62V for ±1% accuracy or ERJ-U6QJR62V for ±5% tolerance matching the original specification.
