IMC1210EB220J Equivalent & Substitute Parts

Part Overview

The IMC1210EB220J is a 22 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 145 mA maximum current with a DC resistance of 3.7Ohm maximum and operates across the temperature range of -55°C to 125°C. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical performance can be maintained across critical parameters including inductance value, tolerance, DC resistance, and operating temperature range, while accommodating variations in current rating, core material, and package dimensions within acceptable engineering tolerances.

Substitute Part Grouping Explanation

Substitution eligibility for the IMC1210EB220J is determined by the following critical parameters:

Mandatory Matching Parameters:

Inductance value: 22 µH
Inductance tolerance: ±5%
DC resistance: 3.7Ohm maximum
Q factor @ 2.52 MHz: 30
Shielding configuration: Unshielded
Mounting type: Surface Mount

Allowable Variation Parameters:

Current rating: Substitute must meet or exceed 145 mA requirement
Core material: Iron powder or ferrite acceptable
Package dimensions: Physical size variations within assembly constraints
Operating temperature: Minimum -40°C acceptable if application does not require -55°C lower limit
Self-resonant frequency: Variation acceptable if electrical performance maintained

The CM322522-220JL from Bourns Inc. qualifies as a substitute based on matching inductance, tolerance, DC resistance, and Q factor specifications. The lower current rating of 105 mA represents a constraint that limits application scope to circuits requiring ≤105 mA operation.

Engineering Selection Recommendations

IMC1210EB220J Selection Criteria:

Applications requiring current operation up to 145 mA
Circuits operating at temperatures below -40°C
Systems where iron powder core characteristics are specified
Designs requiring 1210 (3225 Metric) standard package format

CM322522-220JL Selection Criteria:

Applications with current requirements ≤105 mA
Operating temperature range limited to -40°C minimum
Designs compatible with ferrite core material substitution
Nonstandard package dimensions acceptable for layout constraints
Higher self-resonant frequency (25 MHz) suitable for higher frequency applications

Both parts maintain Active product status, full RoHS3 compliance, and REACH unaffected designation. Selection between these components depends on specific circuit current requirements and minimum operating temperature specifications.

Frequently Asked Questions (FAQ)

Q: Can CM322522-220JL replace IMC1210EB220J in all applications?

A: No. The CM322522-220JL has a maximum current rating of 105 mA compared to 145 mA for the IMC1210EB220J. Substitution is valid only for circuits operating at or below 105 mA. Additionally, the minimum operating temperature is -40°C versus -55°C for the original part.

Q: What is the significance of the different core materials (iron powder vs. ferrite)?

A: Iron powder and ferrite cores exhibit different frequency response and temperature stability characteristics. Both materials are acceptable for this inductance value and tolerance specification. Core material selection depends on specific circuit frequency response requirements and thermal performance needs not specified in this comparison.

Q: Are the physical dimension differences between parts significant?

A: The IMC1210EB220J uses standard 1210 (3.20mm x 2.49mm) packaging, while the CM322522-220JL is nonstandard (3.20mm x 2.50mm) with reduced height (2.20mm vs. 2.41mm). These differences may affect PCB layout and assembly processes. Verify mechanical compatibility with your specific application before substitution.

Q: Do both parts have identical electrical performance at 2.52 MHz?

A: Yes. Both parts specify Q factor of 30 at 2.52 MHz test frequency and maintain identical inductance tolerance (±5%) and DC resistance (3.7Ohm maximum). Electrical performance is equivalent at this frequency.

Q: What compliance certifications apply to both parts?

A: Both IMC1210EB220J and CM322522-220JL are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. Both are classified under ECCN EAR99 and HTSUS 8504.50.8000.
