Equivalent & Substitute Parts for 11R332C

Part Overview

The 11R332C is a 3.3 µH unshielded wirewound inductor manufactured by Murata Power Solutions, designed for through-hole mounting applications. This component is rated for 1.5 A continuous current with a maximum DC resistance of 70mOhm and operates across the temperature range of -40°C to 85°C. The part maintains Active product status and is RoHS3 compliant, making it suitable for modern electronic assemblies requiring fixed inductance filtering, energy storage, or signal conditioning in power conversion and RF circuits.

Substitute parts are identified when equivalent inductance values, tolerance specifications, and physical form factors align with the original component's electrical and mechanical requirements, while accounting for variations in current ratings and DC resistance that may affect circuit performance.

Substitute Part Grouping Explanation

Substitution eligibility for the 11R332C is determined by the following critical parameters:

• Inductance Value: Must be 3.3 µH with ±20% tolerance to maintain circuit inductance specifications
• Mounting Type: Must be Through Hole to ensure PCB assembly compatibility
• Physical Form Factor: Must be Radial, Vertical Cylinder with matching dimensions (0.197" Dia, 0.295" Max Height) for board layout and mechanical fit
• Shielding Configuration: Must be Unshielded to match electromagnetic performance characteristics
• Compliance: Must maintain RoHS3 compliance for regulatory alignment

The RLB0608-3R3ML from Bourns Inc. qualifies as a substitute based on matching inductance, tolerance, mounting type, package configuration, and physical dimensions. Variations in current rating (750 mA vs. 1.5 A) and DC resistance (300mOhm vs. 70mOhm) represent trade-offs that must be evaluated against specific circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the 11R332C and RLB0608-3R3ML maintain Active product status and ROHS3 compliance, ensuring availability and regulatory conformance for current and future applications. The RLB0608-3R3ML extends the operating temperature range to 105°C, providing additional thermal margin in elevated-temperature environments.

Selection between these components depends on circuit current requirements. The 11R332C supports continuous current up to 1.5 A with lower DC resistance (70mOhm), making it suitable for higher-current applications where power dissipation and thermal management are critical. The RLB0608-3R3ML, rated for 750 mA with higher DC resistance (300mOhm), is appropriate for lower-current circuits where the increased resistance does not compromise performance specifications.

Frequently Asked Questions (FAQ)

Q: Can the RLB0608-3R3ML replace the 11R332C in all applications?

A: Substitution is valid only when circuit current requirements do not exceed 750 mA. Applications requiring the full 1.5 A rating of the 11R332C cannot use the RLB0608-3R3ML without circuit redesign or parallel configuration.

Q: How does the difference in DC resistance affect circuit performance?

A: The RLB0608-3R3ML exhibits 300mOhm maximum DC resistance compared to 70mOhm for the 11R332C. At equivalent current levels, the higher resistance results in increased power dissipation and voltage drop across the inductor. Circuit analysis must confirm this trade-off is acceptable for the intended application.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both components share identical radial, vertical cylinder packaging with 0.197" diameter and 0.295" maximum seated height, ensuring direct mechanical compatibility in through-hole PCB layouts.

Q: Do both parts meet the same compliance standards?

A: Both the 11R332C and RLB0608-3R3ML are ROHS3 compliant and REACH unaffected, satisfying equivalent regulatory requirements for modern electronic assemblies.

Q: What is the inductance tolerance for both parts?

A: Both components maintain ±20% inductance tolerance at the specified test frequency, ensuring equivalent inductance accuracy for circuit design calculations.
