IMS05ER221K Equivalent & Substitute Parts

Part Overview

The IMS05ER221K is a 220 µH shielded molded inductor manufactured by Vishay Dale, designed for through-hole applications requiring fixed inductance with moderate current handling. This component is part of the IMS-5 series and provides 125 mA current rating with 5Ohm maximum DC resistance in an axial package configuration.

Identifying equivalent and substitute parts is necessary when the primary component becomes unavailable, when supply chain optimization is required, or when design flexibility allows for alternative qualified sources meeting identical electrical and mechanical specifications.

• Current Rating: 125 mA minimum
• DC Resistance: 5 Ohm maximum
• Package Configuration: Axial through-hole mounting
• Shielding Type: Shielded construction
• Core Material: Ferrite core

The 9250A-224-RC from Bourns Inc. meets all specified electrical and mechanical requirements for direct substitution in applications where the IMS05ER221K is currently deployed.

Parameter Comparison

Engineering Selection Recommendations

The 9250A-224-RC qualifies as a direct substitute based on matching electrical specifications (inductance, current rating, and DC resistance) and identical mechanical configuration (axial through-hole, shielded ferrite core).

The 9250A-224-RC carries active product status and meets ROHS3 compliance requirements. REACH status is unaffected, and the component is classified under ECCN EAR99 with HTSUS code 8504.50.8000.

Selection between the IMS05ER221K and 9250A-224-RC should be based on availability, lead time, packaging requirements (bulk vs. other formats), and supply chain considerations, as both components satisfy the specified electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can the 9250A-224-RC replace the IMS05ER221K in existing designs?

A: Yes. Both components share identical inductance (220 µH), current rating (125 mA), DC resistance (5 Ohm maximum), and package configuration (axial through-hole, shielded ferrite core). No circuit modifications are required.

Q: What are the key parameters that determine substitutability?

A: Inductance value, current rating, DC resistance, package type, shielding configuration, and core material must match. All these parameters are identical between the IMS05ER221K and 9250A-224-RC.

Q: Are there packaging differences between these parts?

A: The IMS05ER221K is specified with standard packaging, while the 9250A-224-RC is available in bulk packaging. Both use identical axial through-hole component geometry.

Q: What compliance certifications apply to the substitute part?

A: The 9250A-224-RC is ROHS3 compliant and REACH unaffected. Moisture sensitivity is not applicable to this component type.

Q: How do the operating temperature ranges compare?

A: The 9250A-224-RC operates across -55°C to 125°C. Operating temperature specifications for the IMS05ER221K are not provided in the available data.
