Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IDCP2218ER150M is determined by the following critical parameters: inductance value (15 µH), current rating capability (minimum 1.3 A or lower if application permits), DC resistance (180 mOhm maximum acceptable for equivalent performance), core material (ferrite, unshielded), and mounting type (surface mount). The substitute parts are grouped into two categories:

Category 1 - Direct Electrical Equivalent (SDR0604-150YL): Matches the primary electrical specifications of 15 µH inductance, 1.3 A current rating, and 140 mOhm DC resistance. This part provides the closest functional replacement with identical electrical performance characteristics.

Category 2 - Reduced Current Rating Substitutes (SDR0603-150ML): Provides 15 µH inductance with 930 mA current rating and 180 mOhm DC resistance. This substitute is applicable only in applications where the circuit current requirement does not exceed 930 mA.

Category 3 - Non-Equivalent (SDR0603-151KL): This part has 150 µH inductance and 320 mA current rating. This is not a functional substitute for the IDCP2218ER150M due to significantly different inductance and current specifications.

Parameter Comparison

Engineering Selection Recommendations

SDR0604-150YL (Bourns Inc.) is the primary substitute for the IDCP2218ER150M. This part maintains identical electrical specifications: 15 µH inductance, 1.3 A current rating, and 140 mOhm maximum DC resistance. Both components are ROHS3 compliant, feature unlimited MSL ratings, and are active products. The SDR0604-150YL provides an extended operating temperature range (-40°C to 125°C versus -25°C to 105°C) and improved saturation current (1.6 A). Physical dimensions are comparable with a maximum height of 4.80mm. This substitute is suitable for direct replacement in all applications where the IDCP2218ER150M is specified.

SDR0603-150ML (Bourns Inc.) is a secondary substitute applicable only when circuit current requirements do not exceed 930 mA. This part shares the 15 µH inductance and ±20% tolerance with the original component. The DC resistance is slightly elevated at 180 mOhm maximum. The SDR0603-150ML offers a lower profile (3.90mm height) and extended temperature range (-40°C to 125°C). ROHS3 compliance and unlimited MSL rating are maintained. Selection of this part requires confirmation that the 930 mA current rating is sufficient for the application.

SDR0603-151KL (Bourns Inc.) is not recommended as a substitute. The 150 µH inductance and 320 mA current rating represent significant deviations from the IDCP2218ER150M specifications and are not functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can SDR0604-150YL replace IDCP2218ER150M in all applications?

A: Yes. The SDR0604-150YL matches the critical electrical parameters: 15 µH inductance, 1.3 A current rating, and 140 mOhm DC resistance. Both components are ROHS3 compliant with unlimited MSL ratings and active product status. Physical dimensions are compatible for surface mount applications.

Q: When is SDR0603-150ML suitable as a substitute?

A: SDR0603-150ML is suitable only when the circuit current requirement does not exceed 930 mA. The part maintains 15 µH inductance and ±20% tolerance. The 180 mOhm DC resistance is acceptable for most applications. The lower profile (3.90mm) may be advantageous in space-constrained designs.

Q: Why is SDR0603-151KL listed but not recommended?

A: SDR0603-151KL has 150 µH inductance and 320 mA current rating. These specifications differ significantly from the IDCP2218ER150M (15 µH, 1.3 A) and are not functionally equivalent. This part is not suitable for direct substitution.

Q: Are there package compatibility concerns?

A: All substitute parts are surface mount components with ferrite drum core construction. The IDCP2218ER150M is 5.80mm × 5.20mm × 4.50mm (max height). SDR0604-150YL is 5.80mm × 5.80mm × 4.80mm (max height), and SDR0603-150ML is 5.80mm × 5.80mm × 3.90mm (max height). Verify PCB layout clearance for the slightly larger footprint of the Bourns SDR0603 and SDR0604 series.

Q: What is the impact of different DC resistance values?

A: The IDCP2218ER150M and SDR0604-150YL both specify 140 mOhm maximum DC resistance. SDR0603-150ML specifies 180 mOhm maximum. In applications with high continuous current, the additional 40 mOhm resistance will produce slightly higher power dissipation. Calculate thermal impact if the circuit operates near the 930 mA limit of SDR0603-150ML.

Q: Do all parts meet the same compliance standards?

A: Yes. IDCP2218ER150M, SDR0603-150ML, SDR0603-151KL, and SDR0604-150YL are all ROHS3 compliant with MSL rating 1 (unlimited). All parts are active products with REACH unaffected status and EAR99 ECCN classification.
