IMC1210EB220K Equivalent & Substitute Parts

Part Overview

The IMC1210EB220K 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 3.7 Ohm DC resistance 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 can be maintained within the specified parameter tolerances while accommodating different packaging formats or inventory availability from alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IMC1210EB220K are qualified based on the following electrical and mechanical parameters:

• Inductance Value: 22 µH (exact match required)
• DC Resistance: 3.7 Ohm Max (exact match required)
• Core Type: Drum Core, Wirewound (exact match required)
• Shielding: Unshielded (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Q Factor @ 2.52 MHz: 30 (exact match required)
• Inductance Test Frequency: 2.52 MHz (exact match required)
• RoHS Compliance: ROHS3 Compliant (required)

Acceptable variations within substitution criteria:

• Current Rating: Substitute parts rated at 105 mA are acceptable for applications where the circuit design does not require the full 145 mA rating of the original part
• Inductance Tolerance: Substitute parts with ±5% tolerance are acceptable where ±10% tolerance is specified
• Operating Temperature Range: Substitute parts with -40°C to 125°C range are acceptable for applications not requiring the -55°C lower limit
• Package Format: Nonstandard package dimensions are acceptable provided physical footprint compatibility is verified in the application circuit
• Core Material: Ferrite core substitutes are acceptable where iron powder cores are specified, provided Q factor and frequency response remain within specification

Parameter Comparison

Engineering Selection Recommendations

Both CM322522-220JL and CM322522-220KL from Bourns Inc. are qualified substitutes for the IMC1210EB220K based on matching electrical specifications and compliance certifications.

CM322522-220KL is the preferred substitute when inductance tolerance matching is required, as it maintains the ±10% tolerance specification of the original part while providing ferrite core construction with improved self-resonant frequency (25 MHz vs. 19 MHz).

CM322522-220JL is suitable for applications where tighter inductance tolerance (±5%) provides design margin, though this represents a more stringent specification than the original part requires.

Both substitutes operate within the -40°C to 125°C temperature range, which covers standard industrial and commercial applications. Applications requiring the extended -55°C lower temperature limit of the original part must retain the IMC1210EB220K.

Both substitutes feature reduced seated height (0.087" vs. 0.095"), which may provide board layout advantages in space-constrained designs. Physical footprint verification is required prior to implementation due to nonstandard package designation of the Bourns components.

All three parts maintain ROHS3 compliance, MSL Level 1 rating, and active production status.

Frequently Asked Questions (FAQ)

Q: Can CM322522-220JL or CM322522-220KL be used in place of IMC1210EB220K without circuit modification?

A: Substitution is permissible when the application circuit does not require the full 145 mA current rating of the original part. The Bourns substitutes are rated for 105 mA maximum current. If the circuit design operates below 105 mA, direct substitution is valid. If circuit current requirements exceed 105 mA, the original IMC1210EB220K must be retained.

Q: What is the difference between CM322522-220JL and CM322522-220KL?

A: Both parts are electrically equivalent with identical inductance (22 µH), DC resistance (3.7 Ohm Max), current rating (105 mA), and Q factor (30 @ 2.52 MHz). The primary difference is inductance tolerance: CM322522-220JL specifies ±5% tolerance, while CM322522-220KL specifies ±10% tolerance matching the original part.

Q: Are the physical dimensions compatible between IMC1210EB220K and the Bourns substitutes?

A: Lateral dimensions are equivalent (0.126" L x 0.098" W with 0.01mm width variation). The Bourns substitutes feature reduced seated height (0.087" vs. 0.095"), which is advantageous for board clearance. Verification of PCB footprint compatibility is required prior to implementation, particularly for applications with height-constrained component placement.

Q: Why does the operating temperature range differ between the original part and substitutes?

A: The IMC1210EB220K operates from -55°C to 125°C, while Bourns substitutes operate from -40°C to 125°C. This difference reflects different core material construction (iron powder vs. ferrite). Applications requiring operation below -40°C must use the original Vishay Dale part.

Q: Are all three parts RoHS compliant?

A: Yes. IMC1210EB220K, CM322522-220JL, and CM322522-220KL are all ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: What is the significance of the self-resonant frequency difference?

A: The IMC1210EB220K exhibits self-resonant frequency of 19 MHz, while Bourns substitutes exhibit 25 MHz. Higher self-resonant frequency in the substitutes indicates improved high-frequency performance characteristics. This difference does not affect substitution validity for standard inductor applications operating below these frequencies.
