IM02ER1R2K Equivalent & Substitute Parts

Part Overview

The IM02ER1R2K is a 1.2 µH unshielded molded inductor manufactured by Vishay Dale, rated for 590 mA with a maximum DC resistance of 180mOhm. This through-hole axial component is designed for applications requiring fixed inductance in compact form factors. Substitute parts are identified based on matching electrical specifications and mechanical compatibility within the IM series and equivalent product lines.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IM02ER1R2K are qualified based on the following critical parameters:

• Inductance Value: 1.2 µH (exact match required)
• DC Resistance: 180mOhm maximum (equal or lower acceptable)
• Shielding Type: Unshielded (must match)
• Mounting Configuration: Through Hole Axial (must match)
• Current Rating: Equal or higher rating acceptable for direct substitution

The Bourns 9230-22-RC meets these criteria with identical inductance and DC resistance specifications, while providing a higher current rating of 825 mA, making it suitable for applications with the same or lower current demands.

Parameter Comparison

Engineering Selection Recommendations

The 9230-22-RC from Bourns Inc. qualifies as a direct substitute for the IM02ER1R2K based on matching inductance, DC resistance, and mechanical form factor. The Bourns component provides enhanced current handling capability (825 mA versus 590 mA), which does not compromise compatibility in applications designed for the original part's 590 mA rating. Both components operate across the same temperature range (-55°C to 125°C) and utilize ferrite cores in unshielded molded configurations.

The Bourns 9230-22-RC carries Active product status and maintains ROHS3 compliance and REACH unaffected designation, meeting current regulatory requirements for electronic component procurement.

Frequently Asked Questions (FAQ)

Q: Can the 9230-22-RC replace the IM02ER1R2K in existing designs?

A: Yes. Both components share identical inductance (1.2 µH) and DC resistance (180mOhm maximum) specifications. The higher current rating of the Bourns part (825 mA) does not create compatibility issues for circuits designed around the 590 mA rating.

Q: Are the physical dimensions compatible?

A: Both components are through-hole axial inductors in molded form factor. The Bourns 9230-22-RC dimensions are 0.095" diameter × 0.250" length (2.41mm × 6.35mm), suitable for standard PCB layouts designed for axial components.

Q: What are the key parameters that determine substitutability?

A: Inductance value, DC resistance, shielding type, and mounting configuration are the primary determinants. Both parts match on all four criteria. Current rating compatibility is secondary; a higher-rated substitute is acceptable for lower-current applications.

Q: Are there temperature or frequency considerations?

A: Both components operate across -55°C to 125°C. The Bourns part specifies a self-resonant frequency of 150MHz and Q factor of 25 at 7.9MHz, providing additional performance data for high-frequency circuit analysis.

Q: What is the packaging difference?

A: The IM02ER1R2K is available in standard packaging, while the 9230-22-RC is supplied in bulk packaging. This affects procurement and handling but does not impact electrical or mechanical compatibility.
