IMS05EB2R2K Equivalent & Substitute Parts

Part Overview

The IMS05EB2R2K is a 2.2 µH shielded molded inductor manufactured by Vishay Dale, rated for 650 mA with a maximum DC resistance of 190mOhm. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. The part operates across a temperature range of -55°C to 105°C and is mounted through-hole in an axial package configuration.

Substitute Part Grouping Explanation

Substitution eligibility for the IMS05EB2R2K is determined by the following critical parameters:

Inductance value: 2.2 µH with ±10% tolerance
Current rating: 650 mA minimum
DC resistance: 190mOhm maximum
Shielding requirement: Shielded configuration
Mounting type: Through-hole axial package
Physical dimensions: 0.162" Dia x 0.410" L (4.11mm x 10.41mm)
Operating temperature range: -55°C to 105°C minimum

Substitute parts must match all electrical specifications and physical form factor. Core material composition (iron powder, ferrite, or iron) and product status variations are secondary considerations that do not prevent functional substitution when primary parameters align.

Engineering Selection Recommendations

For applications requiring ROHS3 compliance, the 9250A-222-RC (Bourns Inc.) is the primary substitute. This part maintains active product status, matches all electrical specifications, and provides an extended operating temperature range to 125°C, offering additional thermal margin beyond the original IMS05EB2R2K specification.

The ER1641-222KM and ER1641-222KP (API Delevan Inc.) are functionally equivalent alternatives with active product status. Both are shielded configurations matching the original part's electromagnetic containment requirements. These parts carry RoHS non-compliant status and are suitable for applications without RoHS mandates.

The ER1641-222KR (API Delevan Inc.) is an unshielded variant. This part differs from the original IMS05EB2R2K in shielding configuration and is suitable only for applications where electromagnetic shielding is not a functional requirement.

Frequently Asked Questions (FAQ)

Q: Can the 9250A-222-RC directly replace the IMS05EB2R2K?

A: Yes. The 9250A-222-RC matches all critical electrical parameters: 2.2 µH inductance, 650 mA current rating, 190mOhm maximum DC resistance, shielded configuration, and identical physical dimensions. The extended temperature range to 125°C provides additional operational margin.

Q: What is the difference between the ER1641-222KM, ER1641-222KP, and ER1641-222KR?

A: The ER1641-222KM and ER1641-222KP are shielded inductors with identical electrical specifications. The ER1641-222KR is an unshielded variant. Shielding selection depends on application requirements for electromagnetic containment. All three share the same inductance, current rating, and DC resistance specifications.

Q: Are there RoHS compliance differences between substitutes?

A: Yes. The 9250A-222-RC is ROHS3 compliant, matching the original IMS05EB2R2K. The ER1641 series (ER1641-222KM, ER1641-222KP, ER1641-222KR) are RoHS non-compliant. Select based on your application's regulatory requirements.

Q: Does core material affect substitution suitability?

A: Core material composition (iron powder, ferrite, or iron) does not prevent functional substitution when all electrical parameters match. The Q factor and self-resonant frequency remain consistent across all substitutes, indicating equivalent performance characteristics.

Q: Can I use ER1641-222KR in place of the shielded IMS05EB2R2K?

A: Only if your application does not require electromagnetic shielding. The ER1641-222KR is unshielded and will not provide the same EMI containment as the original shielded part. Verify shielding requirements before selection.

Q: What packaging options are available for these substitutes?

A: The 9250A-222-RC is supplied in Bulk packaging. The ER1641 series (ER1641-222KM, ER1641-222KP, ER1641-222KR) are supplied in Tape & Reel (TR) configuration. Select based on your procurement and assembly process requirements.
