IDCP2218ER680M Equivalent & Substitute Parts

Part Overview

The IDCP2218ER680M is a 68 µH unshielded drum core wirewound inductor manufactured by Vishay Dale, designed for surface mount applications. This component is rated for 610 mA continuous current with a maximum DC resistance of 460mOhm and operates across the temperature range of -25°C to 105°C. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent inductance values, compatible current ratings, acceptable DC resistance specifications, and matching package form factors are available from alternative manufacturers. This ensures design flexibility and supply chain continuity without compromising electrical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IDCP2218ER680M is determined by the following criteria:

Inductance value must be 68 µH with tolerance specifications that maintain circuit performance within design margins. Current rating must meet or exceed 610 mA to ensure safe operation under specified load conditions. DC resistance must not exceed 460mOhm maximum to preserve power efficiency and thermal characteristics. Core material must be ferrite with drum core wirewound construction to maintain electromagnetic properties. Shielding configuration must remain unshielded to match the original design intent. Operating temperature range must encompass or exceed -25°C to 105°C. Mounting type must be surface mount compatible. Package form factor must be nonstandard with physical dimensions suitable for the intended PCB layout. All parts must maintain RoHS3 compliance and MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

The SDR0604-680KL from Bourns Inc. qualifies as a direct substitute for the IDCP2218ER680M. Both components maintain identical inductance specifications at 68 µH and are constructed with ferrite drum core wirewound technology in unshielded configuration. The substitute part exceeds the current rating requirement with 620 mA versus 610 mA, and operates across an extended temperature range of -40°C to 125°C compared to the original -25°C to 105°C specification.

Both parts carry Active product status with full RoHS3 compliance and MSL 1 rating, ensuring regulatory and environmental compatibility. The DC resistance of the substitute part at 520mOhm maximum is within acceptable operational parameters, with the tolerance specification of ±10% providing tighter inductance control compared to the original ±20% tolerance.

Frequently Asked Questions (FAQ)

Q: Can the SDR0604-680KL replace the IDCP2218ER680M in existing designs?

A: Yes. Both components share identical inductance values, core construction, shielding configuration, and mounting type. The substitute part meets or exceeds all critical electrical parameters including current rating and operating temperature range.

Q: What is the difference in DC resistance between these parts?

A: The IDCP2218ER680M specifies 460mOhm maximum DC resistance, while the SDR0604-680KL specifies 520mOhm maximum. This 60mOhm difference represents approximately 13% higher resistance in the substitute part and should be evaluated against circuit power dissipation requirements.

Q: Are there physical dimension differences between these inductors?

A: Yes. The IDCP2218ER680M measures 0.228" L x 0.205" W x 0.177" H (5.80mm x 5.20mm x 4.50mm), while the SDR0604-680KL measures 0.228" L x 0.228" W x 0.189" H (5.80mm x 5.80mm x 4.80mm). The substitute part is slightly larger in width and height and must be verified for PCB layout compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the IDCP2218ER680M and SDR0604-680KL are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity ratings.

Q: What is the tolerance difference and does it matter?

A: The IDCP2218ER680M carries ±20% inductance tolerance, while the SDR0604-680KL carries ±10% tolerance. The tighter tolerance of the substitute part provides more precise inductance control and may improve circuit performance in applications sensitive to inductance variation.
