IMC1210ES101K Equivalent & Substitute Parts

Part Overview

The IMC1210ES101K is a 100 µH unshielded drum core wirewound inductor manufactured by Vishay Dale, designed for surface mount applications in the 1210 (3225 Metric) package. This component operates across the industrial temperature range of -55°C to 125°C with a maximum DC resistance of 14Ω and a current rating of 73 mA. The part is actively produced and ROHS3 compliant, making it suitable for modern electronic assemblies requiring fixed inductance filtering and energy storage applications.

Substitute parts are identified when equivalent inductance values, tolerance specifications, and core material properties align with the electrical requirements of the original design, while accommodating variations in current ratings, DC resistance, and package dimensions within acceptable engineering tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IMC1210ES101K are qualified based on the following criteria:

• Inductance Match: 100 µH nominal value with ±10% tolerance
• Core Type: Unshielded drum core wirewound construction
• Shielding: Unshielded configuration
• Frequency Characteristics: Q factor of 20 @ 796 kHz and self-resonant frequency in the 8–10 MHz range
• Temperature Range: Operating range of -55°C to 125°C or equivalent
• Package Compatibility: 1210 (3225 Metric) footprint with surface mount mounting
• Compliance: ROHS3 compliant status

Substitutes may vary in current rating (60–73 mA), DC resistance (10–14Ω), core material (iron powder or ferrite), and packaging format (tape & reel or cut tape), provided these variations remain within acceptable design margins for the target application.

Parameter Comparison

Engineering Selection Recommendations

B82422T1104K000 (EPCOS - TDK Electronics): This substitute maintains identical inductance, tolerance, and frequency characteristics. The ferrite core material provides lower DC resistance (11Ω vs. 14Ω) and improved thermal performance. Current rating is reduced to 60 mA, requiring verification that circuit peak currents remain within this limit. AEC-Q200 automotive qualification provides additional reliability assurance. Moisture sensitivity level remains at MSL 1, matching the original part.

CM322522-101KL (Bourns Inc.): This substitute also maintains 100 µH inductance and ±10% tolerance with ferrite core construction. DC resistance is further reduced to 10Ω, offering lower power dissipation. Current rating is 60 mA, identical to the EPCOS option. Operating temperature minimum is -40°C, which may be limiting for applications requiring full -55°C operation. Moisture sensitivity level is MSL 3, requiring controlled storage and handling procedures. Nonstandard package designation requires physical verification of PCB footprint compatibility.

Both substitutes are active products with ROHS3 compliance and REACH unaffected status, meeting modern regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can B82422T1104K000 replace IMC1210ES101K in all applications?

A: Substitution is valid when circuit peak currents remain below 60 mA. The ferrite core material and lower DC resistance (11Ω) may alter circuit behavior in high-frequency filtering applications. Verify that the 8 MHz self-resonant frequency is compatible with your operating bandwidth.

Q: What is the impact of reduced current rating in substitute parts?

A: The IMC1210ES101K supports 73 mA, while both substitutes are rated for 60 mA. If your circuit requires currents above 60 mA, substitution is not appropriate. If operating below 60 mA, the lower rating does not affect performance.

Q: How does core material affect substitution?

A: The original part uses iron powder core, while substitutes use ferrite. Ferrite cores typically exhibit lower DC resistance and different frequency response characteristics. Both materials are unshielded and maintain the same inductance value and Q factor at 796 kHz, making them functionally equivalent for most filtering applications.

Q: Is CM322522-101KL suitable for -55°C operation?

A: CM322522-101KL operates from -40°C to 125°C, which does not cover the full -55°C minimum of the original part. Use this substitute only in applications where the minimum operating temperature is -40°C or higher.

Q: What does MSL 3 moisture sensitivity mean for CM322522-101KL?

A: MSL 3 requires storage at controlled humidity (≤60% RH) and limits floor life to 168 hours after moisture exposure. Implement appropriate moisture control procedures during storage and assembly. MSL 1 parts (IMC1210ES101K and B82422T1104K000) have unlimited floor life and are less sensitive to humidity.

Q: Are package dimensions identical across all three parts?

A: Physical dimensions are similar (0.126" L × 0.098" W), but package designations differ. IMC1210ES101K uses standard 1210 (3225 Metric), B82422T1104K000 uses 2-SMD J-Lead, and CM322522-101KL uses nonstandard designation. Verify PCB footprint compatibility before substitution.
