IMC1210EB100J Equivalent & Substitute Parts

Part Overview

The IMC1210EB100J is a 10 µH unshielded drum core wirewound inductor manufactured by Vishay Dale, designed for surface mount applications in the 1210 (3225 Metric) package. This component is rated for 189 mA maximum current with a DC resistance of 2.1Ohm maximum and operates across the temperature range of -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.

Substitute Part Grouping Explanation

Substitution eligibility for the IMC1210EB100J is determined by the following critical parameters:

Inductance Value: Must be 10 µH with ±5% tolerance
DC Resistance: Must not exceed 2.1Ohm maximum
Current Rating: Must support minimum 189 mA operation
Q Factor: Must maintain 30 @ 2.52 MHz
Self Resonant Frequency: Must be ≥33 MHz
Operating Temperature Range: Must cover -55°C to 125°C minimum
Mounting Type: Surface mount only
Package Compatibility: Physical dimensions and height must accommodate 1210 (3225 Metric) footprint
Regulatory Compliance: ROHS3 compliant

The CM322522-100JL from Bourns Inc. qualifies as a substitute based on matching inductance, tolerance, DC resistance, Q factor, and regulatory compliance. However, the operating temperature range (-40°C to 125°C) is narrower than the main part, and the current rating (140 mA) is lower than the IMC1210EB100J specification.

Engineering Selection Recommendations

The CM322522-100JL is electrically compatible with the IMC1210EB100J for applications where the current requirement does not exceed 140 mA. Both parts maintain identical inductance, tolerance, DC resistance, and Q factor specifications at the test frequency of 2.52 MHz. Both components are ROHS3 compliant and carry EAR99 export classification.

Selection of the CM322522-100JL requires verification that circuit current demands remain within the 140 mA maximum rating. The narrower operating temperature range (-40°C to 125°C versus -55°C to 125°C) must be evaluated against application environmental specifications. The lower seated height (2.20mm versus 2.41mm) provides improved PCB clearance in space-constrained designs. Both parts are surface mount compatible with equivalent footprint dimensions suitable for 1210 package placement.

Frequently Asked Questions (FAQ)

Q: Can the CM322522-100JL replace the IMC1210EB100J in all applications?

A: The CM322522-100JL is suitable for applications where circuit current does not exceed 140 mA. If your design requires the full 189 mA current rating of the IMC1210EB100J, the substitute is not appropriate. Additionally, if operation below -40°C is required, the narrower temperature range of the CM322522-100JL makes it unsuitable.

Q: Are the physical dimensions compatible?

A: Yes. Both inductors share the same length (0.126" / 3.20mm) and width (0.098" / 3.20mm to 2.50mm). The CM322522-100JL has a lower seated height (2.20mm versus 2.41mm), which may be advantageous in compact designs but does not create compatibility issues.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the IMC1210EB100J and CM322522-100JL are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes.

Q: What is the difference in core material?

A: The IMC1210EB100J uses an iron powder core, while the CM322522-100JL uses a ferrite core. Both achieve the same inductance value and Q factor at 2.52 MHz, but core material differences may affect performance in specific frequency ranges or thermal environments outside the specified operating parameters.

Q: Which packaging format should I order?

A: The IMC1210EB100J is available in Bulk packaging, while the CM322522-100JL is supplied in Tape & Reel (TR) format. Packaging selection depends on production volume and assembly line requirements.
