Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RUT2012FR680CS is determined by strict alignment of the following parameters:

Electrical Specifications: Resistance value (680 mOhms), tolerance (±1%), power rating (0.25W), and temperature coefficient (±150ppm/°C) must be identical.

Physical Specifications: Package designation (0805/2012 Metric), number of terminations (2), and maximum seated height must accommodate the same PCB footprint and assembly process.

Compliance Requirements: RoHS3 compliance and Moisture Sensitivity Level 1 status must be maintained.

Composition: Thick film construction ensures equivalent electrical behavior and thermal characteristics.

The ERJ-U6QFR68V from Panasonic Electronic Components satisfies all substitution criteria through matching electrical parameters, identical package dimensions, and equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RUT2012FR680CS and ERJ-U6QFR68V maintain Active product status and satisfy ROHS3 compliance requirements. The components are electrically and mechanically equivalent for standard current sensing applications.

The ERJ-U6QFR68V incorporates additional features including anti-sulfur treatment and AEC-Q200 automotive qualification. These features provide enhanced reliability in corrosive environments and automotive applications but do not affect substitution eligibility for general industrial use cases.

The maximum seated height difference of 0.002" (0.04mm) between components is within typical PCB assembly tolerances and does not impact board-level compatibility.

Selection between these parts should be based on application requirements, supply chain availability, and specific environmental conditions rather than electrical performance, as both components deliver identical functional characteristics.

Frequently Asked Questions (FAQ)

Q: Can ERJ-U6QFR68V replace RUT2012FR680CS in existing designs?

A: Yes. Both components share identical electrical specifications (680 mOhms ±1%, 0.25W), operate across the same temperature range (-55°C to 155°C), and use the same 0805 package footprint. No circuit redesign is required.

Q: Are there physical compatibility concerns between these parts?

A: No. Both components use the 0805 (2012 Metric) package with 2 terminations. The maximum seated height difference of 0.002" (0.04mm) is negligible for standard PCB assembly processes and does not affect placement or soldering.

Q: What is the significance of the AEC-Q200 rating on the Panasonic part?

A: AEC-Q200 certification indicates the component meets automotive industry reliability standards. This qualification is beneficial for automotive applications but does not affect substitution for non-automotive uses.

Q: Do both parts have the same moisture sensitivity classification?

A: Yes. Both components are classified as Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control measures are required during storage or handling.

Q: Are there differences in the anti-sulfur feature of the Panasonic part?

A: The ERJ-U6QFR68V includes anti-sulfur treatment, which provides enhanced resistance to sulfur-containing environments. The RUT2012FR680CS features moisture resistant characteristics. Both are suitable for standard industrial environments; the anti-sulfur feature is an additional benefit for specific applications.

Q: What compliance certifications apply to both parts?

A: Both components are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components in most markets.
