CD105NP-221KC Equivalent & Substitute Parts

Part Overview

The CD105NP-221KC is a 220 µH unshielded surface mount inductor manufactured by Sumida America Components Inc. This fixed inductor is designed for applications requiring 660 mA current rating with a maximum DC resistance of 730mOhm. The component operates across the temperature range of -40°C to 100°C and is classified as Active product status with ROHS3 compliance. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same inductance value, current rating, and DC resistance parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD105NP-221KC is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Inductance value: 220 µH
• Inductance tolerance: ±10%
• Current rating: 660 mA minimum
• DC resistance: 730mOhm maximum
• Shielding configuration: Unshielded

Mechanical Compatibility Requirements:

• Mounting type: Surface Mount
• Package classification: Nonstandard
• Height seated maximum: 5.80mm

Compliance Requirements:

• RoHS3 compliance mandatory
• Moisture Sensitivity Level: 1 (Unlimited)

The SDR1006-221KL from Bourns Inc. meets all electrical and mechanical substitution criteria. Both components share identical inductance specifications, current ratings, and DC resistance maximums. The substitute part maintains surface mount compatibility and equivalent physical height constraints. Both parts are ROHS3 compliant and carry MSL Level 1 rating.

Engineering Selection Recommendations

Primary Part: CD105NP-221KC

The CD105NP-221KC is the specified component with Active product status and full ROHS3 compliance. This part is suitable for direct application when Sumida supply chain availability is confirmed and operating temperature requirements do not exceed 100°C.

Substitute Part: SDR1006-221KL

The SDR1006-221KL from Bourns Inc. is a direct electrical and mechanical equivalent with Active product status and ROHS3 compliance. This substitute part is applicable when:

• Sumida CD105NP-221KC supply is unavailable
• Operating temperature range up to 125°C is required (extended range compared to primary part)
• Bourns supply chain availability is confirmed
• PCB layout accommodates the 9.80mm x 9.80mm footprint (compared to 10.00mm x 9.00mm primary part)

Both parts carry identical electrical specifications and are suitable for equivalent circuit performance. Selection between primary and substitute parts is determined by supply availability and thermal operating requirements.

Frequently Asked Questions (FAQ)

Q: Can the SDR1006-221KL replace the CD105NP-221KC in all applications?

A: The SDR1006-221KL meets all electrical and mechanical substitution criteria for the CD105NP-221KC. Both components share identical inductance (220 µH), current rating (660 mA), DC resistance (730mOhm max), and surface mount configuration. Substitution is valid when PCB layout accommodates the footprint difference (9.80mm x 9.80mm versus 10.00mm x 9.00mm).

Q: What are the key electrical parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: inductance value (220 µH), inductance tolerance (±10%), current rating (660 mA), DC resistance maximum (730mOhm), and shielding configuration (unshielded). All parameters must match or exceed the primary part specifications.

Q: Are there physical dimension differences between these parts?

A: Yes. The CD105NP-221KC measures 10.00mm L x 9.00mm W, while the SDR1006-221KL measures 9.80mm L x 9.80mm W. Both parts share identical height (5.80mm max seated). PCB layout verification is required before substitution.

Q: Do both parts meet the same compliance standards?

A: Both the CD105NP-221KC and SDR1006-221KL are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). Both carry EAR99 ECCN classification and HTSUS code 8504.50.4000.

Q: What is the temperature operating range difference?

A: The CD105NP-221KC operates from -40°C to 100°C. The SDR1006-221KL operates from -40°C to 125°C. The substitute part provides extended high-temperature capability.
