Murata Power Solutions 82224C Equivalent & Substitute Parts

Part Overview

The Murata Power Solutions 82224C is a 220 µH unshielded wirewound inductor rated for 100 mA continuous current with a maximum DC resistance of 8Ohm. This surface mount component in 1210 (3225 Metric) package is designed for applications requiring fixed inductance filtering, energy storage, and signal conditioning in power conversion and RF circuits. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent inductance values, compatible package dimensions, and acceptable current ratings align with application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 82224C is determined by the following critical parameters:

Inductance value must be 220 µH with ±10% tolerance to maintain circuit performance in filtering and energy storage applications. The unshielded configuration is maintained across all substitutes to preserve electromagnetic coupling characteristics. Surface mount mounting type is required for PCB assembly compatibility. Current rating of the substitute must meet or exceed the 100 mA requirement of the original design. DC resistance should not significantly exceed the 8Ohm maximum to avoid excessive power dissipation. Operating temperature range must support the application environment. RoHS3 compliance and unlimited MSL rating ensure regulatory and manufacturing process compatibility.

The Bourns SDR0302-221KL qualifies as a substitute based on matching inductance (220 µH), tolerance (±10%), unshielded configuration, surface mount type, and superior current rating (170 mA). The substitute exhibits lower DC resistance (5.7Ohm Max) and extended operating temperature range (-40°C ~ 125°C), providing performance advantages within the same functional category.

Parameter Comparison

Engineering Selection Recommendations

Both the Murata 82224C and Bourns SDR0302-221KL are active production components with ROHS3 compliance and unlimited moisture sensitivity ratings, ensuring regulatory alignment and manufacturing process compatibility. The SDR0302-221KL provides enhanced performance characteristics including 70% higher current rating capacity (170 mA versus 100 mA) and 28.75% lower DC resistance (5.7Ohm versus 8Ohm maximum), resulting in reduced thermal dissipation. The extended operating temperature range of the substitute (-40°C ~ 125°C versus -40°C ~ 85°C) supports applications requiring elevated temperature operation. Selection between these components should be based on specific application current requirements, thermal constraints, and temperature environment specifications.

Frequently Asked Questions (FAQ)

Q: Can the Bourns SDR0302-221KL directly replace the Murata 82224C in existing designs?

A: Direct substitution is supported when the application current requirement does not exceed 170 mA and the operating temperature range does not exceed 125°C. Both components maintain identical inductance (220 µH) and tolerance (±10%), with the substitute offering superior current handling and lower DC resistance characteristics.

Q: What are the package dimension differences between these components?

A: The Murata 82224C is specified as 1210 (3225 Metric) with dimensions 0.126" L x 0.098" W (3.20mm x 2.50mm) and height 0.091" (2.30mm). The Bourns SDR0302-221KL uses a nonstandard package with dimensions 0.118" L x 0.110" W (3.00mm x 2.80mm) and height 0.110" (2.80mm). PCB layout verification is required to confirm physical fit within the available board space.

Q: How do the DC resistance values affect circuit performance?

A: The Bourns substitute exhibits 5.7Ohm maximum DC resistance compared to 8Ohm maximum for the Murata part. Lower DC resistance reduces I²R power dissipation, thermal generation, and voltage drop across the inductor, improving overall circuit efficiency and thermal management.

Q: Are both components suitable for high-temperature applications?

A: The Murata 82224C operates within -40°C to 85°C, while the Bourns SDR0302-221KL extends to -40°C to 125°C. Applications requiring sustained operation above 85°C require the Bourns substitute to maintain specified electrical characteristics and reliability.

Q: What compliance certifications apply to both components?

A: Both the Murata 82224C and Bourns SDR0302-221KL are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8504.50.4000. Both components carry unlimited moisture sensitivity level (MSL 1) rating.
