Parameter Comparison

Engineering Selection Recommendations

The 1025R-22K from API Delevan Inc. is suitable for applications currently specified with IM02EB1R2K inductors. The substitute part maintains active product status, ensuring long-term availability and supply chain continuity. Both components carry ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for equivalent applications.

The 1025R-22K current rating of 620 mA exceeds the original 590 mA specification, providing operational margin without introducing performance degradation. All electrical characteristics, thermal operating range, and physical form factors remain consistent between the two parts.

Frequently Asked Questions (FAQ)

Q: Can the 1025R-22K be used as a direct replacement for IM02EB1R2K on existing circuit boards?

A: Yes. The 1025R-22K maintains identical inductance value, tolerance, DC resistance, Q factor, self-resonant frequency, operating temperature range, and physical dimensions. Through-hole axial mounting compatibility is preserved.

Q: What is the significance of the higher current rating on the 1025R-22K?

A: The 1025R-22K is rated for 620 mA compared to the IM02EB1R2K at 590 mA. This higher rating provides operational margin and does not negatively impact circuit performance when the original design operates at or below 590 mA.

Q: Are there compliance or regulatory differences between these parts?

A: Both parts carry ROHS3 compliance and REACH unaffected status. No regulatory barriers exist for substitution in equivalent applications.

Q: Why is the IM02EB1R2K classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Vishay Dale. The 1025R-22K, maintained in active production by API Delevan Inc., provides functional continuity for designs requiring 1.2 µH axial inductors with the specified electrical and mechanical characteristics.

Q: Are the physical dimensions identical between both parts?

A: Yes. Both components measure 0.095" diameter by 0.250" length (2.41mm x 6.35mm), ensuring identical PCB footprint and mounting compatibility.
