RUT2012JR130CS Equivalent & Substitute Parts

Part Overview

The RUT2012JR130CS is a 130 mOhms ±5% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated for 0.25W (1/4W) power dissipation in 0805 (2012 Metric) package configuration. 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 with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Substitute parts are necessary when original inventory is unavailable, when design requirements demand enhanced tolerance specifications, increased power ratings, or automotive-grade certifications such as AEC-Q200 compliance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RUT2012JR130CS is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Resistance value: 130 mOhms (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (minimum requirement)
• Moisture Sensitivity Level: 1 (Unlimited) or equivalent

Allowable Variation Parameters:

• Tolerance: ±5% or tighter (±1% acceptable as upgrade)
• Power Rating: 0.25W (1/4W) or higher (0.5W/1/2W acceptable as upgrade)
• Temperature Coefficient: ±150ppm/°C or equivalent
• Features: Current Sense required; additional features (Automotive AEC-Q200, Anti-Sulfur) acceptable

All four substitute parts meet these criteria and are classified as direct functional equivalents with enhanced or equivalent electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (Same Power Rating - 0.25W/1/4W):

ERJ-U6SFR13V and ERJ-U6SJR13V maintain identical power ratings to the RUT2012JR130CS. ERJ-U6SFR13V provides tighter tolerance (±1%) with Anti-Sulfur and Automotive AEC-Q200 features. ERJ-U6SJR13V matches the original ±5% tolerance while adding Anti-Sulfur and Automotive AEC-Q200 certifications. Both are suitable for direct board-level replacement without thermal design modifications.

Upgraded Substitution (Higher Power Rating - 0.5W/1/2W):

ERJ-6DSFR13V and ERJ-6DSJR13V offer increased power dissipation capability (0.5W vs. 0.25W). ERJ-6DSFR13V combines ±1% tolerance with Automotive AEC-Q200 compliance. ERJ-6DSJR13V maintains ±5% tolerance with Automotive AEC-Q200 compliance. These parts are suitable when design margins require enhanced thermal performance or when automotive-grade reliability is mandated by system specifications.

All substitute parts maintain ROHS3 compliance, unlimited moisture sensitivity level (MSL 1), and identical operating temperature range (-55°C ~ 155°C). All parts are Active status with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can ERJ-6DSFR13V replace RUT2012JR130CS in a 1:1 substitution?

A: ERJ-6DSFR13V is functionally compatible as a substitute. The primary differences are enhanced tolerance (±1% vs. ±5%), increased power rating (0.5W vs. 0.25W), and Automotive AEC-Q200 certification. Physical dimensions remain identical (0805 package). The higher power rating does not create compatibility issues in standard applications.

Q: What is the difference between ERJ-U6SFR13V and ERJ-U6SJR13V?

A: Both parts share identical specifications except tolerance: ERJ-U6SFR13V specifies ±1% tolerance while ERJ-U6SJR13V specifies ±5% tolerance. Both maintain 0.25W power rating matching the original RUT2012JR130CS. Selection depends on circuit tolerance requirements.

Q: Are the Panasonic ERJ series parts suitable for automotive applications?

A: ERJ-6DSFR13V, ERJ-6DSJR13V, ERJ-U6SFR13V, and ERJ-U6SJR13V all carry Automotive AEC-Q200 certification. The RUT2012JR130CS does not specify AEC-Q200 compliance. Panasonic parts are suitable for automotive-grade applications; the original Samsung part is not certified for this requirement.

Q: Does package height variation affect PCB assembly compatibility?

A: Package height differences exist: RUT2012JR130CS maximum 0.024" (0.61mm), ERJ-6D series maximum 0.028" (0.70mm), ERJ-U6S series maximum 0.026" (0.65mm). All variations remain within standard 0805 package specifications. Height differences do not affect reflow soldering or standard PCB assembly processes.

Q: Can I use a 0.5W rated part (ERJ-6DSFR13V or ERJ-6DSJR13V) in place of the 0.25W original?

A: Yes. Higher power rating provides additional thermal margin and does not create electrical incompatibility. The circuit will operate identically. Use of higher-rated components is acceptable engineering practice when inventory or design requirements necessitate substitution.

Q: What compliance certifications are common across all parts?

A: All parts (original and substitutes) are ROHS3 compliant, REACH unaffected, classified as EAR99, and carry HTSUS code 8533.21.0030. All maintain Moisture Sensitivity Level 1 (Unlimited). All operate across -55°C to 155°C temperature range.
