RUT2012JR330CS Equivalent & Substitute Parts

Part Overview

The RUT2012JR330CS is a 330 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. The part maintains Active product status with 1039 units in current inventory stock.

Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and package compatibility align with the main part's functional requirements. Substitution becomes necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit tolerance or feature variations.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (ERJ-U6QJR33V): This Panasonic part provides identical tolerance (±5%) and all core electrical specifications matching the RUT2012JR330CS. Both components are ROHS3 compliant, MSL 1 rated, and maintain the same operating temperature range. The ERJ-U6QJR33V includes AEC-Q200 automotive qualification and anti-sulfur features, representing an upgrade in environmental robustness while maintaining functional equivalence. Inventory availability is 17629 units.

Higher Precision Alternative (ERJ-U6QFR33V): This Panasonic part offers tighter tolerance (±1% versus ±5%), providing superior resistance accuracy for applications requiring enhanced precision. All other electrical and mechanical parameters remain equivalent to the main part. This option is suitable for designs where tolerance stack-up analysis permits the use of tighter tolerance components. Inventory availability is 26184 units.

Both substitute parts are Active status components with full ROHS3 and REACH compliance, ensuring long-term availability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can ERJ-U6QFR33V replace RUT2012JR330CS in all applications?

A: ERJ-U6QFR33V is electrically and mechanically compatible with RUT2012JR330CS. The tighter ±1% tolerance of ERJ-U6QFR33V provides superior accuracy compared to the ±5% tolerance of the main part. Applications requiring the original ±5% tolerance specification will operate within acceptable parameters with the ±1% substitute. Physical dimensions and package compatibility are identical.

Q: What is the difference between ERJ-U6QFR33V and ERJ-U6QJR33V?

A: Both parts are Panasonic 0805 package 330 mOhms thick film resistors with identical physical dimensions and operating temperature ranges. The primary difference is tolerance: ERJ-U6QFR33V is ±1% while ERJ-U6QJR33V is ±5%. Both include AEC-Q200 automotive certification and anti-sulfur features. Selection depends on tolerance requirements of the specific application.

Q: Are the substitute parts suitable for current sensing applications?

A: Yes. Both ERJ-U6QFR33V and ERJ-U6QJR33V are thick film 0805 package resistors with 330 mOhms resistance and 0.25W power rating, meeting the electrical requirements for current sensing circuits. The Panasonic parts include anti-sulfur features and automotive-grade certification, providing enhanced reliability in demanding environments.

Q: Will the substitute parts fit the same PCB footprint?
