Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IDCP2218ER151M is determined by the following critical parameters: inductance value (150 µH), current rating capability (minimum 400 mA), DC resistance (maximum 1.1Ohm), core material (ferrite), shielding configuration (unshielded), and mounting type (surface mount). All identified substitutes maintain the same inductance specification and core material. The substitute parts are grouped based on their ability to meet or exceed the current rating and DC resistance requirements while maintaining compatibility with the surface mount package category.

SDR0603-151KL and SDR0604-151KL are direct functional equivalents, both rated for 400 mA with 1.1Ohm maximum DC resistance and 150 µH inductance. SDR0603-180ML differs in inductance value (18 µH) and current rating (820 mA) and is not a direct substitute for the primary application but may serve alternative circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

SDR0604-151KL is the primary recommended substitute for the IDCP2218ER151M. Both parts maintain identical inductance (150 µH), current rating (400 mA), and DC resistance (1.1Ohm Max) specifications. SDR0604-151KL offers improved tolerance (±10% versus ±20%), extended operating temperature range (-40°C to 125°C), and is ROHS3 compliant. The part is available in Tape & Reel packaging and has 1304 units in stock.

SDR0603-151KL is an alternative substitute with matching inductance and tolerance of ±10%. However, the current rating is reduced to 320 mA and DC resistance is increased to 1.43Ohm, making it suitable only for applications where the 400 mA rating is not a hard requirement.

SDR0603-180ML is not recommended as a direct substitute due to significantly different inductance (18 µH versus 150 µH) and is applicable only to circuits designed for lower inductance values.

Frequently Asked Questions (FAQ)

Q: Can SDR0603-151KL replace IDCP2218ER151M in all applications?

A: SDR0603-151KL matches the inductance and tolerance specifications but has a reduced current rating of 320 mA compared to the 400 mA rating of IDCP2218ER151M. Substitution is valid only if the circuit current requirement does not exceed 320 mA.

Q: What is the difference between SDR0604-151KL and SDR0603-151KL?

A: Both are 150 µH inductors from Bourns Inc. with ±10% tolerance. SDR0604-151KL maintains the full 400 mA current rating and 1.1Ohm DC resistance of the original part. SDR0603-151KL has a reduced current rating of 320 mA and increased DC resistance of 1.43Ohm. SDR0604-151KL is the preferred substitute.

Q: Is SDR0603-180ML compatible with the IDCP2218ER151M circuit?

A: SDR0603-180ML has an inductance value of 18 µH, which is significantly different from the 150 µH specification of IDCP2218ER151M. This part is not a functional substitute for the original application and should only be used in circuits specifically designed for 18 µH inductance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all identified substitute parts (SDR0603-151KL, SDR0603-180ML, and SDR0604-151KL) are ROHS3 compliant, matching the compliance status of the IDCP2218ER151M.

Q: What are the packaging differences between the main part and substitutes?

A: IDCP2218ER151M is supplied in Tape & Reel (TR) packaging. SDR0603-151KL is available in Cut Tape (CT) and Digi-Reel® packaging. SDR0603-180ML and SDR0604-151KL are supplied in Tape & Reel (TR) packaging, matching the original part format.
