IMC1210EB100K Equivalent & Substitute Parts

Part Overview

The IMC1210EB100K 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 2.1 Ohm maximum and operates across the temperature range of -55°C to 125°C. The part maintains active product status and is ROHS3 compliant.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when alternative packaging formats better suit manufacturing requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IMC1210EB100K is determined by the following critical parameters:

• Inductance Value: Must be 10 µH
• DC Resistance: Must not exceed 2.1 Ohm maximum
• Current Rating: Must support minimum 189 mA operation
• Package Dimensions: Physical footprint must be compatible with 1210 (3225 Metric) mounting area
• Shielding Configuration: Must be unshielded
• Mounting Type: Must be surface mount
• Compliance: Must maintain ROHS3 compliance

The substitute parts CM322522-100JL and CM322522-100KL from Bourns Inc. meet these core electrical and mechanical requirements. Both maintain the 10 µH inductance specification, 2.1 Ohm maximum DC resistance, and unshielded drum core wirewound construction. Physical dimensions remain compatible at 0.126" L x 0.098" W (3.20mm x 2.50mm), with height-seated maximum of 0.087" (2.20mm). Both substitute parts are ROHS3 compliant and maintain active product status.

Parameter Comparison

Engineering Selection Recommendations

Both CM322522-100JL and CM322522-100KL maintain ROHS3 compliance and active product status, meeting regulatory requirements equivalent to the primary part. The substitute parts utilize ferrite core material in place of iron powder, resulting in a lower current rating of 140 mA compared to the 189 mA specification of the IMC1210EB100K. Applications operating at or below 140 mA can utilize either substitute without electrical performance degradation.

CM322522-100JL offers ±5% inductance tolerance compared to the ±10% tolerance of both the primary part and CM322522-100KL, providing tighter inductance specification when required. CM322522-100KL maintains ±10% tolerance matching the primary part specification.

Operating temperature range differs between the primary part (-55°C to 125°C) and both substitutes (-40°C to 125°C). Applications requiring operation below -40°C must retain the IMC1210EB100K.

Physical dimensions remain compatible across all three parts, with substitute parts featuring slightly reduced seated height (0.087" versus 0.095"), providing additional clearance in constrained mounting environments.

Frequently Asked Questions (FAQ)

Q: Can CM322522-100JL or CM322522-100KL be used in applications requiring 189 mA current?

A: No. Both substitute parts are rated for 140 mA maximum current, which is 49 mA below the primary part specification. Applications requiring 189 mA operation must use the IMC1210EB100K.

Q: What is the difference between CM322522-100JL and CM322522-100KL?

A: Both parts are electrically identical with the same 10 µH inductance, 2.1 Ohm maximum DC resistance, and 140 mA current rating. The primary difference is packaging format: CM322522-100JL is supplied in Tape & Reel (TR) format, while CM322522-100KL is supplied in Cut Tape (CT) & Digi-Reel® format. CM322522-100JL also offers ±5% inductance tolerance versus ±10% for CM322522-100KL.

Q: Are the physical dimensions compatible for PCB layout?

A: Yes. All three parts maintain compatible 1210 (3225 Metric) package footprints with dimensions of 0.126" L x 0.098" W. Substitute parts feature slightly reduced seated height (0.087" maximum versus 0.095" maximum), which may provide additional clearance in space-constrained designs.

Q: What is the impact of core material differences between iron powder and ferrite?

A: The primary part uses iron powder core material while substitute parts use ferrite core material. Both configurations maintain the specified 10 µH inductance and 2.1 Ohm maximum DC resistance. Core material differences may affect frequency response characteristics and EMI behavior in specific circuit applications.

Q: Can these parts be used in applications operating below -40°C?

A: No. The substitute parts are rated for -40°C to 125°C operating temperature range, while the primary part supports -55°C to 125°C. Applications requiring operation below -40°C must use the IMC1210EB100K.

Q: Are all three parts ROHS3 compliant?

A: Yes. The IMC1210EB100K, CM322522-100JL, and CM322522-100KL are all ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements.
