IMC1210EB330K Equivalent & Substitute Parts

Part Overview

The IMC1210EB330K is a 33 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 112 mA maximum current with 6Ohm maximum DC resistance 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 (MSL 1).

Substitute parts are identified when equivalent inductance values, similar current ratings, compatible package dimensions, and matching electrical characteristics are available from alternative manufacturers. This ensures design flexibility and supply chain continuity while maintaining circuit performance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IMC1210EB330K is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 33 µH ±10% tolerance
• Package dimensions: 1210 (3225 Metric) form factor with compatible height
• Core type: Drum core wirewound construction
• Shielding configuration: Unshielded
• Surface mount mounting type

Secondary Compatibility Factors:

• Current rating: Minimum 70 mA (substitute must support circuit current requirements)
• DC resistance: Maximum 5.6Ohm to 6Ohm range
• Operating temperature: Minimum -40°C to 125°C overlap
• Q factor and self-resonant frequency within acceptable application bandwidth
• RoHS3 compliance and MSL 1 rating

The CM322522-330KL from Bourns Inc. qualifies as a substitute based on matching inductance, package footprint, core construction, and electrical performance within the specified tolerance bands.

Parameter Comparison

Engineering Selection Recommendations

IMC1210EB330K (Primary Selection): The Vishay Dale IMC1210EB330K is the original specification component with Active product status. It provides the highest current rating at 112 mA and the widest operating temperature range (-55°C to 125°C). This part is suitable for applications requiring maximum thermal performance and current headroom. RoHS3 compliance and REACH unaffected status confirm regulatory alignment.

CM322522-330KL (Substitute Selection): The Bourns Inc. CM322522-330KL is qualified as a substitute for applications where the 70 mA current rating is sufficient. This part maintains identical inductance and tolerance specifications with marginally lower DC resistance (5.6Ohm vs. 6Ohm maximum). The ferrite core material differs from the iron powder core of the primary part, resulting in a slightly higher self-resonant frequency (17MHz vs. 16MHz). Operating temperature range is -40°C to 125°C, which covers standard industrial applications but excludes extended low-temperature operation below -40°C. Both parts carry Active product status, RoHS3 compliance, and MSL 1 rating. Physical dimensions are nearly identical with the substitute offering a lower profile (2.20mm vs. 2.41mm seated height).

Selection between these parts depends on circuit current requirements and minimum operating temperature specifications.

Frequently Asked Questions (FAQ)

Q: Can the CM322522-330KL replace the IMC1210EB330K in all applications?

A: The CM322522-330KL is suitable for applications where circuit current does not exceed 70 mA and minimum operating temperature remains above -40°C. If your design requires the full 112 mA current rating or operation below -40°C, the IMC1210EB330K is the required selection.

Q: What is the difference between iron powder and ferrite core materials in these inductors?

A: Both core materials are provided in the specifications. Iron powder cores (IMC1210EB330K) and ferrite cores (CM322522-330KL) exhibit different frequency response characteristics, reflected in their self-resonant frequencies (16MHz vs. 17MHz). The choice depends on application bandwidth requirements.

Q: Are the physical dimensions compatible for PCB layout?

A: Both parts share identical footprint dimensions (3.20mm x 2.49-2.50mm length and width). The CM322522-330KL has a lower seated height (2.20mm vs. 2.41mm), which may provide clearance advantages in space-constrained designs.

Q: Do both parts meet regulatory requirements?

A: Both the IMC1210EB330K and CM322522-330KL are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity) ratings. Both are suitable for regulated applications.

Q: What is the inductance tolerance for these parts?

A: Both parts maintain ±10% inductance tolerance at the 2.52 MHz test frequency, ensuring consistent circuit performance across the specified tolerance band.
