IMS05EB560K Equivalent & Substitute Parts

Part Overview

The IMS05EB560K is a 56 µH shielded molded inductor manufactured by Vishay Dale, rated for 190 mA with a maximum DC resistance of 2.23 Ohm. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement in existing circuit designs.

Substitute Part Grouping Explanation

Substitute parts for the IMS05EB560K are qualified based on the following electrical and mechanical parameters:

Inductance value: 56 µH ±10%
Current rating: 190 mA minimum
DC resistance: 2.23 Ohm maximum
Shielding configuration: Shielded
Q factor: 50 @ 2.5 MHz
Self-resonant frequency: 25 MHz
Operating temperature range: -55°C minimum to 105°C minimum
Mounting type: Through Hole
Package: Axial
Physical dimensions: 0.162" Dia x 0.410" L (4.11 mm x 10.41 mm)
Core material: Ferrite

The 9250A-563-RC from Bourns Inc. qualifies as a direct substitute with identical electrical specifications and extended operating temperature range (-55°C ~ 125°C). The ER1641-563KM and ER1641-563KP variants from API Delevan Inc. meet all electrical and mechanical requirements. The ER1641-563KR variant is unshielded and does not qualify as a substitute due to shielding mismatch.

Engineering Selection Recommendations

The 9250A-563-RC from Bourns Inc. is the primary recommended substitute. This part maintains full electrical and mechanical compatibility with the IMS05EB560K while offering active product status and ROHS3 compliance. The extended operating temperature range (-55°C ~ 125°C) provides additional thermal margin compared to the original specification.

The ER1641-563KM and ER1641-563KP from API Delevan Inc. are qualified alternatives that meet all electrical and mechanical requirements. Both parts are active products with identical inductance, current rating, and DC resistance specifications. Selection between these variants should be based on packaging requirements: ER1641-563KM and ER1641-563KP are supplied in Tape & Reel format. Note that both API Delevan variants are RoHS non-compliant, which may impact suitability for applications with RoHS compliance requirements.

The ER1641-563KR variant is not recommended as a substitute due to unshielded configuration, which does not meet the shielding requirement of the original IMS05EB560K specification.

Frequently Asked Questions (FAQ)

Q: Can the 9250A-563-RC directly replace the IMS05EB560K in existing designs?

A: Yes. The 9250A-563-RC maintains identical electrical specifications (56 µH, 190 mA, 2.23 Ohm DCR) and mechanical compatibility (axial through-hole, 0.162" Dia x 0.410" L). Both parts are shielded molded inductors with matching Q factor and self-resonant frequency characteristics.

Q: What is the difference between the ER1641-563KM and ER1641-563KP variants?

A: Both variants meet identical electrical and mechanical specifications for the IMS05EB560K. The distinction lies in packaging format, with both supplied in Tape & Reel configuration. Selection should be based on assembly process requirements and inventory management practices.

Q: Why is the ER1641-563KR not listed as a substitute?

A: The ER1641-563KR is an unshielded inductor variant. The IMS05EB560K is specified as shielded, making the unshielded ER1641-563KR incompatible for direct substitution in applications where shielding performance is required.

Q: Are there compliance differences between substitute options?

A: Yes. The 9250A-563-RC is ROHS3 compliant. The ER1641-563KM and ER1641-563KP are RoHS non-compliant. Applications with RoHS compliance mandates should prioritize the 9250A-563-RC.

Q: What is the operating temperature range difference between substitutes?

A: The 9250A-563-RC operates from -55°C to 125°C, providing 20°C additional upper temperature margin compared to the IMS05EB560K and API Delevan variants, which operate to 105°C maximum.
