RUT2012FR160CS Equivalent & Substitute Parts Reference

Part Overview

The RUT2012FR160CS is a 160 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 with moisture-resistant construction and operates across the temperature range of -55°C to 155°C. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain considerations, or application-specific performance enhancements while maintaining electrical and mechanical compatibility within the 0805 package form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RUT2012FR160CS is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria (Non-Negotiable):

• Resistance value: 160 mOhms
• Tolerance: ±1%
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Operating temperature range: -55°C to 155°C minimum
• RoHS3 compliance status
• Tape & Reel packaging format

Secondary Compatibility Parameters:

• Temperature coefficient within ±150ppm/°C specification
• Moisture sensitivity level MSL 1 or better
• Number of terminations: 2
• REACH unaffected status

The identified substitute parts ERJ-6DSFR16V and ERJ-U6SFR16V from Panasonic Electronic Components meet all primary substitution criteria. Both parts maintain identical resistance value, tolerance, package geometry, and operating temperature specifications. Both are manufactured as thick film compositions with RoHS3 compliance and MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

RUT2012FR160CS (Samsung Electro-Mechanics) - Primary Specification: Select this part when the design specifies 0.25W power rating with moisture-resistant thick film construction. This component is suitable for standard current sensing applications with baseline thermal requirements. Active product status ensures continued availability and supply chain stability.

ERJ-U6SFR16V (Panasonic Electronic Components) - Direct Equivalent: This part provides electrical and mechanical equivalence to the RUT2012FR160CS with identical 0.25W power rating and ±150ppm/°C temperature coefficient. The ERJ-U6SFR16V adds anti-sulfur protection and AEC-Q200 automotive qualification. Height-seated specification (0.026" / 0.65mm) is marginally higher than the main part (0.024" / 0.61mm) but remains within standard PCB assembly tolerances. Select this substitute when automotive-grade reliability or anti-sulfur environmental protection is required, or when Samsung sourcing is unavailable.

ERJ-6DSFR16V (Panasonic Electronic Components) - Higher Power Alternative: This part maintains electrical equivalence in resistance, tolerance, and temperature range but provides elevated 0.5W power rating. The temperature coefficient specification (0/+150ppm/°C) differs from the main part's ±150ppm/°C symmetrical specification. Height-seated specification (0.028" / 0.70mm) represents the maximum among the three options. AEC-Q200 automotive qualification is included. Select this substitute only when application thermal requirements exceed 0.25W dissipation capacity, as the higher power rating may introduce unnecessary cost and board space considerations in standard designs.

All three parts maintain Active product status, full RoHS3 compliance, MSL 1 rating, and REACH unaffected status, ensuring regulatory and supply chain compatibility.

Frequently Asked Questions (FAQ)

Q: Can ERJ-6DSFR16V replace RUT2012FR160CS in all applications?

A: ERJ-6DSFR16V is electrically equivalent in resistance, tolerance, and temperature range. However, the 0.5W power rating exceeds the RUT2012FR160CS specification of 0.25W. In applications where the circuit design limits current dissipation to 0.25W or less, the higher power rating introduces no functional benefit. The temperature coefficient specification differs (0/+150ppm/°C versus ±150ppm/°C), which may affect precision in temperature-sensitive current sensing circuits. Substitution is valid only when the application can accommodate the higher power rating and temperature coefficient variation.

Q: What is the difference between ERJ-U6SFR16V and ERJ-6DSFR16V?

A: Both are Panasonic thick film 160 mOhms ±1% resistors in 0805 package with AEC-Q200 qualification. ERJ-U6SFR16V matches the RUT2012FR160CS power rating (0.25W) and temperature coefficient (±150ppm/°C), with added anti-sulfur protection. ERJ-6DSFR16V provides double the power rating (0.5W) with asymmetrical temperature coefficient (0/+150ppm/°C). For direct substitution of RUT2012FR160CS, ERJ-U6SFR16V is the preferred choice.

Q: Are there height differences that affect PCB assembly?

A: Yes. RUT2012FR160CS has maximum seated height of 0.024" (0.61mm). ERJ-U6SFR16V is 0.026" (0.65mm), and ERJ-6DSFR16V is 0.028" (0.70mm). These differences fall within standard PCB assembly tolerances and do not typically affect reflow soldering or component placement. However, in applications with tight vertical clearance constraints, verify that the substitute part height remains acceptable for the specific board design.

Q: Do all three parts have the same moisture sensitivity requirements?

A: Yes. All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Storage, handling, and assembly procedures are identical across all three parts. No special precautions are required when substituting between these components.

Q: Which substitute part should be selected for automotive applications?

A: Both Panasonic parts (ERJ-6DSFR16V and ERJ-U6SFR16V) carry AEC-Q200 automotive qualification. The RUT2012FR160CS does not list AEC-Q200 certification. For automotive applications requiring AEC-Q200 compliance, select ERJ-U6SFR16V as the direct equivalent, or ERJ-6DSFR16V if higher power dissipation is needed.

Q: Are all parts available in Tape & Reel packaging?

A: Yes. All three parts are supplied in Tape & Reel (TR) format, ensuring compatibility with automated assembly equipment and production workflows. No packaging format conversion is required when substituting between these components.
