Part Overview

The IMS05EB220K is a 22 µH shielded molded inductor manufactured by Vishay Dale, rated for 290 mA continuous current with a maximum DC resistance of 960 mOhm. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The part operates across a temperature range of -55°C to 105°C and is housed in an axial through-hole package measuring 0.162" diameter by 0.410" length.

Engineering Selection Recommendations

9250A-223-RC (Bourns Inc.) is the primary recommended substitute. This part is active in production, ROHS3 compliant, and provides an extended operating temperature range to 125°C compared to the original 105°C maximum. Electrical specifications are identical to the IMS05EB220K. Packaging is bulk format.

ER1641-223KM and ER1641-223KP (API Delevan Inc.) are functionally equivalent alternatives with active product status. Both are supplied in tape and reel packaging. These parts are RoHS non-compliant and operate within the original temperature range of -55°C to 105°C. Selection between these two variants depends on packaging requirements.

ER1641-223KR (API Delevan Inc.) differs from other substitutes in shielding configuration, featuring an unshielded design. This part is classified as military-grade per MIL-PRF-39010/03 specification. Selection of this variant is appropriate only when unshielded operation is acceptable for the application. RoHS non-compliant status applies.

Frequently Asked Questions (FAQ)

Q: Can the 9250A-223-RC replace the IMS05EB220K directly?

A: Yes. The 9250A-223-RC maintains all critical electrical parameters: 22 µH inductance, 290 mA current rating, 960 mOhm maximum DC resistance, and identical Q factor and self-resonant frequency specifications. Physical dimensions and axial through-hole mounting are identical. The extended temperature range to 125°C provides additional operational margin.

Q: What is the difference between the ER1641-223KM and ER1641-223KP?

A: Both parts are electrically and mechanically identical. The distinction is packaging format: ER1641-223KM and ER1641-223KP are both supplied in tape and reel configuration. Selection depends on procurement and assembly process requirements.

Q: Why is ER1641-223KR listed as a substitute if it is unshielded?

A: The ER1641-223KR maintains all specified electrical parameters including inductance, current rating, DC resistance, Q factor, and self-resonant frequency. Shielding configuration is a design consideration rather than a substitution barrier. This part is appropriate for applications where electromagnetic shielding is not a functional requirement.

Q: Are there compliance differences between substitute options?

A: Yes. The 9250A-223-RC is ROHS3 compliant. The ER1641 series parts (ER1641-223KM, ER1641-223KP, ER1641-223KR) are RoHS non-compliant. Selection should account for end-product regulatory requirements and customer specifications.

Q: Does the extended temperature range of the 9250A-223-RC affect compatibility?

A: No. The extended range to 125°C is a superset of the original -55°C to 105°C specification. The 9250A-223-RC operates within the original temperature envelope and provides additional margin for high-temperature applications.

Q: What packaging options are available?

A: The 9250A-223-RC is supplied in bulk packaging. The ER1641-223KM, ER1641-223KP, and ER1641-223KR are supplied in tape and reel format. Selection depends on assembly process compatibility and procurement volume requirements.
