CD105NP-220MC Equivalent & Substitute Parts

Part Overview

The CD105NP-220MC is a 22 µH unshielded surface mount inductor manufactured by Sumida America Components Inc. This fixed inductor is designed for applications requiring 1.95 A current rating with 100mOhm maximum DC resistance. The component operates across the temperature range of -40°C to 100°C and is classified as Active product status. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Substitute Part Grouping Explanation

Substitution eligibility for the CD105NP-220MC is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

Inductance value of 22 µH (±20% tolerance acceptable)
Current rating of 1.95 A minimum
DC resistance of 100mOhm maximum
Unshielded configuration
Ferrite core material

Mechanical Compatibility Requirements:

Engineering Selection Recommendations

CD105NP-220MC (Primary Part): The CD105NP-220MC remains the primary selection when Sumida supply is available. This component carries Active product status and full ROHS3 compliance. Current inventory of 4400 pieces supports immediate procurement.

SDR1006-220ML (Substitute Part): The SDR1006-220ML from Bourns Inc. is qualified as a direct substitute when CD105NP-220MC availability is constrained. This part maintains electrical equivalence across all critical parameters: 22 µH inductance, 1.95 A current rating, and 100mOhm maximum DC resistance. The substitute provides extended operating temperature range (-40°C to 125°C versus -40°C to 100°C), representing enhanced thermal capability. Both components are ROHS3 compliant and carry Active product status. The SDR1006-220ML is available in higher inventory (6700 pieces) and utilizes drum core wirewound construction. Physical dimensions are compatible within the nonstandard package classification, with seated height matching at 5.80mm maximum.

Frequently Asked Questions (FAQ)

Q: Can SDR1006-220ML replace CD105NP-220MC in existing designs?

A: Yes. Both inductors provide identical 22 µH inductance, 1.95 A current rating, and 100mOhm maximum DC resistance. Surface mount mounting type and nonstandard package dimensions are compatible. Both components operate across -40°C to 100°C minimum, with SDR1006-220ML extending to 125°C. Electrical performance is equivalent for circuit applications designed around CD105NP-220MC specifications.

Q: What are the physical dimension differences?

A: CD105NP-220MC footprint is 10.00mm x 9.00mm. SDR1006-220ML footprint is 9.80mm x 9.80mm. Both components have identical maximum seated height of 5.80mm. The SDR1006-220ML footprint is slightly smaller, making it compatible with PCB layouts designed for the primary part.

Q: Are both parts RoHS compliant?

A: Yes. Both CD105NP-220MC and SDR1006-220ML carry ROHS3 Compliant status and meet regulatory requirements for restricted substance compliance.

Q: What is the difference in core construction?

A: CD105NP-220MC uses ferrite core construction. SDR1006-220ML uses drum core wirewound construction with ferrite material. Both achieve equivalent electrical specifications at the specified inductance and current ratings.

Q: Which part should be selected for new designs?

A: Selection depends on supply availability and design flexibility. Both parts meet identical electrical requirements. CD105NP-220MC is the original specification. SDR1006-220ML offers extended temperature range and higher current saturation rating (3.5A versus unspecified for primary part), providing additional design margin in thermal-constrained applications.

Q: What is the packaging difference?

A: CD105NP-220MC is supplied in Tape & Reel (TR) packaging. SDR1006-220ML is supplied in Cut Tape (CT) & Digi-Reel® packaging. Both are suitable for automated assembly processes.
