IMC1210EB151K Equivalent & Substitute Parts

Part Overview

The IMC1210EB151K is a 150 µH unshielded drum core wirewound inductor manufactured by Vishay Dale, designed for surface mount applications in the 1210 (3225 Metric) package. This component operates at a maximum current rating of 65 mA with a DC resistance of 15Ohm maximum and is rated for operating temperatures from -55°C to 125°C. The part is currently active in production and RoHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances for this inductance value and package class.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IMC1210EB151K is determined by the following critical parameters:

• Inductance Value: 150 µH with ±10% tolerance
• Current Rating: Minimum 65 mA required for equivalent operation
• DC Resistance: 15Ohm maximum
• Core Type: Ferrite drum core, unshielded
• Package Compatibility: 1210 (3225 Metric) surface mount footprint
• Regulatory Compliance: RoHS3 compliant, REACH unaffected

The substitute part CM322522-151KL from Bourns Inc. meets the inductance, DC resistance, core material, and regulatory requirements. However, the current rating of this substitute is 50 mA, which is lower than the main part's 65 mA specification. This difference must be evaluated based on circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

The CM322522-151KL from Bourns Inc. is a qualified substitute for the IMC1210EB151K when circuit current requirements do not exceed 50 mA. Both parts maintain RoHS3 compliance and REACH unaffected status, meeting regulatory requirements for equivalent applications.

The primary consideration for substitution is the current rating differential: the Bourns part is rated at 50 mA versus the Vishay Dale part at 65 mA. Selection of the substitute requires confirmation that the application's maximum operating current remains within the 50 mA limit.

The operating temperature range of the substitute is -40°C to 125°C, which is narrower than the main part's -55°C to 125°C range. Applications requiring operation below -40°C must use the original IMC1210EB151K.

Both parts are available in different packaging formats: the main part in Bulk and the substitute in Tape & Reel (TR). Packaging selection depends on assembly and inventory requirements.

Frequently Asked Questions (FAQ)

Q: Can CM322522-151KL replace IMC1210EB151K in all applications?

A: Substitution is valid only when the circuit current requirement does not exceed 50 mA and the operating temperature range remains within -40°C to 125°C. If the application requires 65 mA current capacity or operation below -40°C, the original IMC1210EB151K must be used.

Q: What is the significance of the current rating difference?

A: The current rating indicates the maximum continuous current the inductor can handle without exceeding saturation or thermal limits. The IMC1210EB151K supports 65 mA, while CM322522-151KL supports 50 mA. Operating the substitute above 50 mA may result in inductor saturation and performance degradation.

Q: Are the inductance values and tolerances identical?

A: Yes. Both parts provide 150 µH inductance with ±10% tolerance, meeting the same electrical specification for inductance value.

Q: What is the difference in packaging between these parts?

A: The IMC1210EB151K is supplied in Bulk packaging, while CM322522-151KL is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes, while Bulk packaging is used for manual assembly or smaller quantities.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the IMC1210EB151K and CM322522-151KL are RoHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements.

Q: Why is the self-resonant frequency different between the two parts?

A: The self-resonant frequency of 6.5 MHz for the IMC1210EB151K and 8 MHz for the CM322522-151KL reflects differences in the internal construction and winding characteristics. Both values are provided for reference in frequency-dependent circuit analysis.
