RUT2012JR200CS Equivalent & Substitute Parts

Part Overview

The RUT2012JR200CS is a 200 mOhms ±5% 0.25W thick film chip resistor manufactured by Samsung Electro-Mechanics in the 0805 (2012 Metric) package. This current sense resistor is designed for moisture-resistant applications and operates across the temperature range of -55°C to 155°C. The part is active in production status and ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Equivalent and substitute parts are identified when alternative manufacturers offer 0805 package resistors with matching or superior electrical specifications, including resistance value, tolerance, power rating, and operating temperature range. Substitute parts may include enhanced features such as automotive qualification (AEC-Q200) or improved tolerance specifications while maintaining mechanical and electrical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RUT2012JR200CS is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 200 mOhms
• Package / Case: 0805 (2012 Metric)
• Operating temperature range: -55°C ~ 155°C minimum
• Composition: Thick Film
• RoHS compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variations in Substitutes:

• Tolerance: Equal or tighter (±5% or ±1%)
• Power rating: Equal or higher (0.25W or 0.5W)
• Temperature coefficient: Within specified range
• Features: May include additional qualifications (AEC-Q200, Anti-Sulfur) without compromising base functionality
• Packaging format: Tape & Reel (TR) or Cut Tape (CT) formats are interchangeable for component selection purposes

The four identified substitute parts from Panasonic Electronic Components meet all mandatory parameters while offering either improved tolerance specifications or enhanced automotive qualification ratings.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (Equivalent Specifications):

ERJ-U6SJR20V and ERJ-U6SFR20V from Panasonic are the closest functional equivalents to the RUT2012JR200CS. Both maintain the 0.25W power rating and 0805 package format. ERJ-U6SJR20V matches the ±5% tolerance specification exactly, while ERJ-U6SFR20V offers improved ±1% tolerance. Both include Anti-Sulfur and AEC-Q200 automotive qualification features and are ROHS3 compliant with MSL 1 rating.

Higher Power Rating Alternatives:

ERJ-6DSJR20V and ERJ-6DSFR20V from Panasonic provide 0.5W power rating in the same 0805 package. These parts are suitable for applications requiring higher power dissipation capability while maintaining the 200 mOhms resistance and operating temperature range. ERJ-6DSJR20V matches the ±5% tolerance, while ERJ-6DSFR20V provides ±1% tolerance. Both include AEC-Q200 automotive qualification and are ROHS3 compliant with MSL 1 rating.

Compliance and Production Status:

All substitute parts are active in production status with ROHS3 compliance and REACH unaffected designation. All parts carry EAR99 ECCN classification and identical HTSUS code 8533.21.0030. Selection between substitutes depends on application requirements for tolerance precision and power dissipation capability rather than compliance or regulatory considerations.

Frequently Asked Questions (FAQ)

Q: Can ERJ-6DSJR20V be used as a direct replacement for RUT2012JR200CS?

A: ERJ-6DSJR20V is functionally compatible with RUT2012JR200CS for the 200 mOhms resistance value, ±5% tolerance, and 0805 package. The primary difference is the power rating: ERJ-6DSJR20V is rated at 0.5W compared to RUT2012JR200CS at 0.25W. This higher power rating does not prevent substitution; it provides additional thermal margin. The part is ROHS3 compliant with MSL 1 rating, matching the original specification.

Q: What is the difference between ERJ-U6SFR20V and ERJ-6DSFR20V?

A: Both parts are 200 mOhms ±1% thick film resistors in 0805 package with ROHS3 compliance and MSL 1 rating. The key differences are: ERJ-U6SFR20V is rated at 0.25W with Anti-Sulfur feature, while ERJ-6DSFR20V is rated at 0.5W without the Anti-Sulfur designation. Both include AEC-Q200 automotive qualification. Selection depends on power dissipation requirements and whether anti-sulfur protection is needed for the application environment.

Q: Are all substitute parts suitable for current sense applications?

A: Yes. All four substitute parts from Panasonic are specified for current sense applications. The RUT2012JR200CS is also designated as a current sense resistor. All substitute parts maintain the thick film composition and 200 mOhms resistance value required for current sensing circuits.

Q: Does the AEC-Q200 rating on substitute parts affect compatibility?

A: No. AEC-Q200 automotive qualification is an additional feature that does not affect electrical or mechanical compatibility. Parts with AEC-Q200 rating meet automotive reliability standards and can be used in non-automotive applications without compatibility issues. The presence of this rating provides additional assurance of quality and reliability.

Q: Can I use ERJ-U6SFR20V (±1% tolerance) instead of RUT2012JR200CS (±5% tolerance)?

A: Yes. ERJ-U6SFR20V with ±1% tolerance is a valid substitute for RUT2012JR200CS with ±5% tolerance. The tighter tolerance specification of the substitute part provides improved accuracy and is fully compatible with applications designed for the original ±5% tolerance specification.

Q: What is the significance of the temperature coefficient difference between parts?

A: RUT2012JR200CS specifies ±150ppm/°C temperature coefficient, while ERJ-6DSJR20V and ERJ-6DSFR20V specify 0/+150ppm/°C. Both specifications define acceptable resistance variation over the -55°C to 155°C operating range. The 0/+150ppm/°C specification indicates unidirectional drift, while ±150ppm/°C indicates bidirectional drift. Both are within acceptable parameters for current sense applications.

Q: Are packaging format differences (Tape & Reel vs. Cut Tape) significant for component selection?

A: Packaging format differences relate to supply and handling methods rather than component functionality. RUT2012JR200CS is supplied in Tape & Reel format. Substitute parts are available in both Tape & Reel and Cut Tape formats. The electrical and mechanical specifications remain identical regardless of packaging format. Selection of packaging format depends on assembly process requirements and inventory management practices.
