11R224C Equivalent & Substitute Parts

Part Overview

The 11R224C is a 220 µH unshielded wirewound inductor manufactured by Murata Power Solutions Inc., designed for through-hole mounting applications. This component is rated for 240 mA maximum current with a DC resistance of 2.4Ohm maximum 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 supply and signal processing circuits.

Substitute parts are identified when equivalent inductance values, current ratings, and mechanical compatibility can be maintained within acceptable tolerance ranges, ensuring functional interchangeability in the target application.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 11R224C is determined by the following critical parameters:

• Inductance Value: Must be 220 µH with ±10% tolerance to maintain circuit performance
• Current Rating: Must support minimum 240 mA operation without saturation
• DC Resistance: Must not exceed 2.4Ohm to preserve power efficiency characteristics
• Mounting Type: Must be Through Hole to ensure PCB compatibility
• Package / Case: Must be Radial, Vertical Cylinder with matching dimensional specifications (0.197" Dia, 0.295" Max Height)
• Shielding: Must be Unshielded to match electromagnetic profile
• Compliance: Must maintain RoHS3 compliance for regulatory alignment

The RLB0608-221KL from Bourns Inc. qualifies as a direct substitute based on these parameters.

Parameter Comparison

Engineering Selection Recommendations

The RLB0608-221KL qualifies as a direct substitute for the 11R224C based on matching inductance, tolerance, mechanical dimensions, and regulatory compliance. Both components are Active products with RoHS3 certification, ensuring supply continuity and regulatory alignment.

The primary consideration is the current rating differential: the substitute is rated for 200 mA versus the original 240 mA specification. This 40 mA reduction requires application-level verification to confirm adequate design margin. The DC resistance variance of 0.1Ohm is within acceptable engineering tolerance for most filtering and energy storage applications.

The extended operating temperature range of the substitute (-40°C to 105°C versus -40°C to 85°C) provides additional thermal headroom without introducing compatibility concerns.

Frequently Asked Questions (FAQ)

Q: Can the RLB0608-221KL replace the 11R224C in all applications?

A: Mechanical and electrical compatibility is confirmed for inductance, tolerance, resistance, and package specifications. However, the 40 mA lower current rating requires application-level assessment. If the circuit operates below 200 mA, substitution is valid. If operation approaches or exceeds 200 mA, the original 11R224C is required.

Q: Are there dimensional differences between these parts?

A: No. Both components share identical package dimensions: 0.197" diameter (5.00mm) and 0.295" maximum seated height (7.50mm). PCB footprints and mounting holes are compatible.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 11R224C and RLB0608-221KL are RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Q: What is the impact of the 0.1Ohm DC resistance difference?

A: The RLB0608-221KL exhibits 2.5Ohm maximum resistance versus 2.4Ohm for the original. This 4.2% variance typically has negligible impact on filtering performance and power dissipation in standard applications. Circuit-specific thermal analysis may be required for high-current or continuous-duty scenarios.

Q: Why does the substitute support a wider operating temperature range?

A: The RLB0608-221KL uses a ferrite drum core construction, which provides thermal stability across -40°C to 105°C. This extended range does not affect substitution eligibility and may provide additional design margin in temperature-sensitive applications.
