RUT2012JR360CS Equivalent & Substitute Parts

Part Overview

The RUT2012JR360CS is a 360 mOhms ±5% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 0805 (2012 Metric) package format. This component is rated for 0.25W (1/4W) power dissipation and is designed for current sense applications with moisture-resistant characteristics. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1). Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, application-specific certifications, or design optimization needs.

Substitute Part Grouping Explanation

Substitution of the RUT2012JR360CS is permissible when the replacement component satisfies all critical parameters: identical 360 mOhms resistance value, 0805 package format, 0.25W power rating, and thick film composition. The tolerance specification of ±5% establishes the acceptable resistance range (342 mOhms to 378 mOhms). Substitute parts must maintain the same operating temperature range (-55°C ~ 155°C), temperature coefficient (±150ppm/°C), and two-terminal configuration. Regulatory compliance (ROHS3, MSL 1) and electrical characteristics must be preserved or enhanced. Tolerance values tighter than ±5% (such as ±1%) represent acceptable substitutes as they fall within the original specification envelope. Additional certifications or enhanced features (such as AEC-Q200 automotive qualification or anti-sulfur properties) do not preclude substitution when core electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-U6QFR36V from Panasonic Electronic Components qualifies as a direct substitute for the RUT2012JR360CS. Both components share identical resistance values, power ratings, package formats, and operating temperature ranges. The substitute part features a tighter tolerance specification (±1% versus ±5%), which provides enhanced precision without compromising compatibility. Both parts maintain ROHS3 compliance, unlimited moisture sensitivity level (MSL 1), and identical regulatory classifications (REACH Unaffected, EAR99). The maximum seated height differential (0.026" versus 0.024") remains within acceptable mechanical tolerances for standard PCB assembly processes. The ERJ-U6QFR36V includes AEC-Q200 automotive qualification and anti-sulfur properties, which represent additional certifications that do not conflict with the original application requirements. Selection between these parts should be based on inventory availability, lead time requirements, and application-specific certification needs rather than electrical or mechanical incompatibility.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-U6QFR36V replace the RUT2012JR360CS in a current sense application?

A: Yes. Both components are rated for current sense applications with identical 360 mOhms resistance, 0.25W power rating, and thick film composition. The substitute part's ±1% tolerance provides equal or superior performance within the original ±5% specification envelope.

Q: Are there any physical compatibility concerns with the ERJ-U6QFR36V?

A: No. Both parts use the 0805 (2012 Metric) package with identical length and width dimensions (0.079" x 0.049"). The maximum seated height of the substitute (0.026") exceeds the main part (0.024") by 0.002", which is within standard PCB assembly tolerances and does not affect board-level compatibility.

Q: Does the tighter tolerance of the ERJ-U6QFR36V affect substitution eligibility?

A: No. A tolerance of ±1% is more restrictive than the original ±5% specification and therefore represents an acceptable substitute. The substitute part will perform within the original design envelope.

Q: Are regulatory and compliance certifications identical between these parts?

A: Yes. Both the RUT2012JR360CS and ERJ-U6QFR36V are ROHS3 compliant, REACH Unaffected, and classified as EAR99. Both carry HTSUS code 8533.21.0030. The ERJ-U6QFR36V includes additional AEC-Q200 automotive qualification, which does not conflict with the original part's certifications.

Q: What is the moisture sensitivity level for both parts?

A: Both components are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions and unlimited shelf life under standard storage conditions.

Q: Can these parts be used interchangeably in production?

A: Yes. The electrical and mechanical parameters are compatible for direct substitution. PCB layout, footprint, and assembly processes designed for the RUT2012JR360CS require no modification to accommodate the ERJ-U6QFR36V.

Q: Are there any temperature-related performance differences?

A: No. Both parts operate across the identical temperature range (-55°C ~ 155°C) with the same temperature coefficient (±150ppm/°C), ensuring equivalent thermal performance characteristics.
