IM02ER820K Equivalent & Substitute Parts

Part Overview

The IM02ER820K is a 82 µH unshielded molded inductor manufactured by Vishay Dale, designed for through-hole applications requiring fixed inductance in axial configuration. This component is part of the IM series and is currently in stock with 732 units available. The need for equivalent and substitute parts arises from supply chain considerations, design flexibility, and application-specific performance requirements where alternative manufacturers' components meet or exceed the electrical and mechanical specifications of the original part.

Key Parameters

Substitute Part Grouping Explanation

The 9230-66-RC from Bourns Inc. qualifies as a direct substitute based on the following critical parameters:

• Inductance Match: Both parts specify 82 µH, meeting the core functional requirement
• DC Resistance Match: Both parts maintain 7.3 Ohm Max DCR, ensuring equivalent power dissipation characteristics
• Package Compatibility: Both use axial through-hole configuration, enabling direct mechanical and electrical integration
• Shielding Type: Both are unshielded molded inductors, maintaining electromagnetic behavior consistency
• Core Material: Both utilize ferrite core construction
• Temperature Range: The Bourns part operates within -55°C ~ 125°C, matching the thermal envelope

The Bourns 9230-66-RC provides an enhanced current rating of 130 mA compared to the original 88 mA specification, offering improved headroom for applications without requiring design modification.

Parameter Comparison

Engineering Selection Recommendations

Selection between the IM02ER820K and 9230-66-RC should be based on the following criteria:

IM02ER820K (Vishay Dale) is appropriate when:

• Original design specification explicitly requires Vishay Dale components
• Supply chain preference favors Vishay Dale inventory
• Current application operates within the 88 mA specification with no margin requirement

9230-66-RC (Bourns Inc.) is appropriate when:

• Supply of the original part is constrained
• Application benefits from the higher 130 mA current rating
• RoHS3 compliance certification is required for the end application
• Bourns inventory availability is preferred

Both parts maintain identical inductance, DC resistance, and thermal operating range, ensuring functional equivalence in circuit performance. The Bourns component carries explicit RoHS3 compliance documentation, which may be relevant for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can the 9230-66-RC directly replace the IM02ER820K in existing designs?

A: Yes. Both components share identical inductance (82 µH), DC resistance (7.3 Ohm Max), axial through-hole package configuration, and operating temperature range (-55°C ~ 125°C). The Bourns part provides higher current rating (130 mA vs. 88 mA), which does not create compatibility issues in applications designed for the lower rating.

Q: What are the key electrical parameters that determine substitution eligibility?

A: The critical parameters are inductance value (82 µH), DC resistance (7.3 Ohm Max), and current rating. The substitute must meet or exceed these specifications. Both parts satisfy these requirements.

Q: Are there any mechanical differences between these parts?

A: Both parts use axial through-hole mounting with molded construction. No mechanical redesign or PCB layout modification is required for substitution.

Q: Does the Bourns part have any compliance advantages?

A: The 9230-66-RC carries explicit RoHS3 compliance certification and REACH Unaffected status. If your application requires documented compliance documentation, the Bourns part provides this certification.

Q: What is the tolerance specification for inductance?

A: The Bourns 9230-66-RC specifies ±10% inductance tolerance. The original IM02ER820K tolerance is not provided in the available documentation.
