RUT2012JR160CS Equivalent & Substitute Parts

Part Overview

The RUT2012JR160CS is a 160 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 and operates across the temperature range of -55°C to 155°C. The part maintains Active product status and is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified parameter ranges, enabling component selection flexibility for procurement, inventory management, and design optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RUT2012JR160CS is determined by strict adherence to the following critical parameters:

Primary Substitution Criteria:

• Resistance value: 160 mOhms (exact match required)
• Package: 0805 (2012 Metric) form factor (exact match required)
• Composition: Thick Film (exact match required)
• Operating temperature range: -55°C to 155°C minimum (equal or wider range acceptable)
• Moisture Sensitivity Level: 1 (Unlimited) or equivalent
• RoHS compliance: ROHS3 Compliant (minimum requirement)

Secondary Parameters (Allowable Variation):

• Tolerance: ±5% or tighter (±1% acceptable as superior specification)
• Power rating: 0.25W (1/4W) or higher (0.5W/1/2W acceptable as superior specification)
• Temperature coefficient: ±150ppm/°C or tighter (0/+150ppm/°C acceptable)

All four identified substitute parts meet the primary criteria. Variations in tolerance and power rating represent enhanced or equivalent electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (Identical Specifications):

ERJ-U6SJR16V represents the closest functional equivalent to RUT2012JR160CS. Both parts share identical resistance (160 mOhms), tolerance (±5%), power rating (0.25W/1/4W), package (0805), and operating temperature range (-55°C to 155°C). Both maintain ROHS3 compliance and MSL 1 rating. The primary distinction is manufacturer origin (Panasonic versus Samsung) and the addition of Anti-Sulfur and Automotive AEC-Q200 features in the Panasonic variant, which do not conflict with the original specification.

Enhanced Specification Substitutes:

ERJ-U6SFR16V provides tighter tolerance (±1% versus ±5%) while maintaining identical power rating and package specifications. This represents an enhanced electrical performance option suitable for applications requiring improved accuracy.

ERJ-6DSJR16V and ERJ-6DSFR16V both offer increased power rating (0.5W/1/2W versus 0.25W/1/4W) in the same 0805 package footprint. These parts accommodate higher current sensing applications while maintaining the 160 mOhms resistance value and -55°C to 155°C operating range. ERJ-6DSFR16V combines the higher power rating with ±1% tolerance.

All substitute parts maintain Active product status and full ROHS3 compliance, ensuring regulatory and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can ERJ-U6SJR16V replace RUT2012JR160CS in a current sensing circuit?

A: Yes. Both parts share identical electrical specifications (160 mOhms ±5%, 0.25W, -55°C to 155°C) and package form factor (0805). The Panasonic part includes additional Anti-Sulfur and AEC-Q200 automotive features that do not conflict with the original design requirements.

Q: What is the difference between the 0.25W and 0.5W power-rated substitutes?

A: Power rating indicates maximum continuous power dissipation capability. The 0.5W-rated parts (ERJ-6DSJR16V, ERJ-6DSFR16V) accommodate higher current sensing applications. Both 0.25W and 0.5W variants fit the same 0805 package footprint. Selection depends on circuit current requirements; higher power-rated parts are suitable for higher current applications.

Q: Are tolerance differences significant for current sensing applications?

A: Tolerance affects measurement accuracy. The ±1% tolerance variants (ERJ-U6SFR16V, ERJ-6DSFR16V) provide tighter resistance value control compared to ±5% parts. Selection depends on circuit accuracy requirements; ±1% parts are suitable for applications requiring improved precision.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All identified substitutes maintain ROHS3 compliance, MSL 1 (Unlimited) moisture sensitivity rating, and Active product status. Temperature operating ranges (-55°C to 155°C) are identical across all parts.

Q: Can I use ERJ-6DSJR16V in place of RUT2012JR160CS without circuit modification?

A: Yes. The 0805 package footprint is identical, and the 160 mOhms resistance value matches exactly. The higher 0.5W power rating is a superior specification that does not require circuit changes. Verify that PCB layout and thermal management accommodate the slightly increased height (0.028" versus 0.024" maximum seated height).

Q: What is the significance of the Anti-Sulfur feature in ERJ-U6S series parts?

A: Anti-Sulfur treatment protects against sulfur-induced corrosion in high-sulfur environments. This feature is present in ERJ-U6SJR16V and ERJ-U6SFR16V but does not affect substitution eligibility for standard applications. It represents an additional environmental protection capability.
