IM02ER2R2K Equivalent & Substitute Parts

Part Overview

The IM02ER2R2K is a 2.2 µH unshielded molded inductor manufactured by Vishay Dale, designed for through-hole axial mounting applications. This component operates at 395 mA maximum current with 400mOhm DC resistance, serving as a fixed inductance element in electronic circuits requiring stable magnetic energy storage at specified frequency ranges.

The IM series remains in active production status. Substitute parts are identified to address inventory availability, extended lead times, or specific application requirements where electrical and mechanical parameters remain compatible within defined tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IM02ER2R2K are qualified based on the following critical parameters:

• Inductance Value: 2.2 µH ±10% tolerance
• DC Resistance: 400mOhm maximum
• Current Rating: Minimum 395 mA (substitutes may exceed this value)
• Mounting Configuration: Through-hole axial package
• Physical Dimensions: 0.095" Dia x 0.250" L (2.41mm x 6.35mm)
• Shielding Type: Unshielded molded construction
• Frequency Characteristics: Q @ 7.9 MHz and self-resonant frequency alignment

The identified substitutes maintain electrical equivalence across inductance, tolerance, DC resistance, and frequency response parameters. Physical package compatibility ensures direct board-level replacement without layout modification.

Engineering Selection Recommendations

All three components maintain active product status and ROHS3 compliance, qualifying them for equivalent circuit applications. Selection between the IM02ER2R2K and substitute parts should be based on:

9230-28-RC (Bourns Inc.): Provides 550 mA current rating, exceeding the original specification by 155 mA. Maintains identical DC resistance, inductance, and frequency characteristics. Operating temperature range matches the original part (-55°C ~ 125°C). REACH Unaffected status confirmed.

1025R-28K (API Delevan Inc.): Provides 415 mA current rating, exceeding the original specification by 20 mA. Maintains identical DC resistance, inductance, and frequency characteristics. Operating temperature range is -55°C ~ 105°C, which is 20°C lower than the original part at the upper limit. REACH Unaffected status confirmed.

Both substitutes are electrically and mechanically compatible for direct replacement in applications operating within the specified parameter ranges.

Frequently Asked Questions (FAQ)

Q: Can the 9230-28-RC replace the IM02ER2R2K in all applications?

A: Yes, provided the application operates within the common parameter envelope. The 9230-28-RC maintains identical inductance (2.2 µH), DC resistance (400mOhm), frequency response (Q @ 7.9MHz, 115MHz self-resonant), and operating temperature range (-55°C ~ 125°C). The higher current rating (550 mA vs. 395 mA) does not restrict compatibility.

Q: What is the difference between the 1025R-28K and the original IM02ER2R2K?

A: The 1025R-28K is electrically equivalent in inductance, tolerance, DC resistance, and frequency characteristics. The primary difference is the reduced upper operating temperature limit (105°C vs. 125°C). Applications requiring operation above 105°C must use the original IM02ER2R2K or the 9230-28-RC.

Q: Are all three parts physically identical?

A: Yes. All three components share identical physical dimensions (0.095" Dia x 0.250" L / 2.41mm x 6.35mm), axial package configuration, and through-hole mounting type, enabling direct board-level substitution without layout modification.

Q: Do all substitutes meet the same compliance standards?

A: All three parts are ROHS3 compliant. The 9230-28-RC and 1025R-28K carry confirmed REACH Unaffected status. Compliance documentation should be verified with the respective manufacturer for specific application requirements.

Q: What core material differences exist between these inductors?

A: The IM02ER2R2K uses ferrite core material (Vishay Dale specification). The 1025R-28K uses iron core material (API Delevan specification). The 9230-28-RC core material is ferrite (Bourns specification). Core material differences do not affect the electrical parameters specified in this comparison.
