CD105NP-330MC Equivalent & Substitute Parts

Part Overview

The CD105NP-330MC is a 33 µH unshielded surface mount inductor manufactured by Sumida America Components Inc. This fixed inductor is rated for 1.5 A continuous current with a maximum DC resistance of 120 mOhm and operates across the temperature range of -40°C to 100°C. The component is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, supply chain considerations, or design flexibility within the allowed parameter tolerances.

Substitute Part Grouping Explanation

Substitution of the CD105NP-330MC is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Inductance value: 33 µH (tolerance variations within ±20% for main part and ±10% for substitute are acceptable within design margins)
• Current rating: 1.5 A minimum
• DC resistance: 120 mOhm maximum
• Core material: Ferrite
• Shielding configuration: Unshielded

Mechanical Equivalence Criteria:

• Mounting type: Surface Mount
• Package classification: Nonstandard
• Height seated maximum: 5.80 mm (0.228")
• Footprint compatibility within dimensional tolerance

Compliance Criteria:

• RoHS3 compliance required
• Moisture sensitivity level: 1 (Unlimited)
• ECCN and HTSUS classifications maintained

The SDR1006-330KL from Bourns Inc. meets all substitution criteria within these defined parameters.

Engineering Selection Recommendations

CD105NP-330MC (Primary Selection): The CD105NP-330MC remains the primary component choice when Sumida supply is available. This part is Active status with 2820 pieces in current inventory. The component meets all RoHS3 compliance requirements and carries MSL 1 rating for unlimited moisture exposure tolerance.

SDR1006-330KL (Substitute Selection): The SDR1006-330KL from Bourns Inc. is a direct electrical and mechanical substitute. This part is also Active status with 3214 pieces in inventory. The substitute offers tighter inductance tolerance (±10% versus ±20%) and extended operating temperature range (-40°C to 125°C versus -40°C to 100°C). Both components maintain identical DC resistance specifications, current ratings, and physical dimensions. RoHS3 compliance and MSL 1 rating are maintained. The substitute is classified as Drum Core, Wirewound construction type, which does not affect substitution eligibility within the specified parameter constraints.

Selection between these parts is determined by availability, supply chain requirements, and design margin considerations. Both components satisfy the electrical and mechanical requirements for surface mount 33 µH inductor applications at 1.5 A rating.

Frequently Asked Questions (FAQ)

Q: Can the SDR1006-330KL replace the CD105NP-330MC in existing designs?

A: Yes. Both components share identical inductance (33 µH), current rating (1.5 A), DC resistance (120 mOhm maximum), core material (ferrite), shielding configuration (unshielded), and physical dimensions (5.80 mm seated height). Surface mount footprint compatibility is maintained. Both are RoHS3 compliant with MSL 1 rating.

Q: What are the dimensional differences between these parts?

A: The CD105NP-330MC measures 10.00 mm L × 9.00 mm W. The SDR1006-330KL measures 9.80 mm L × 9.80 mm W. Both components have identical seated height of 5.80 mm maximum. These dimensional variations are within acceptable tolerance for surface mount placement and do not affect substitution eligibility.

Q: Does the tighter tolerance of the substitute part affect compatibility?

A: No. The SDR1006-330KL carries ±10% inductance tolerance compared to the CD105NP-330MC at ±20%. Tighter tolerance on the substitute part does not create incompatibility; it provides improved specification margin. Both parts meet the 33 µH inductance requirement.

Q: Are there temperature range considerations for substitution?

A: The SDR1006-330KL operates across -40°C to 125°C, while the CD105NP-330MC operates across -40°C to 100°C. If the application requires operation above 100°C, the substitute part provides extended temperature capability. For applications within -40°C to 100°C, both parts are equivalent.

Q: What is the significance of the Drum Core, Wirewound construction type on the substitute?

A: The SDR1006-330KL is specified as Drum Core, Wirewound construction. This construction type does not affect electrical equivalence or substitution eligibility when all electrical parameters (inductance, current rating, DC resistance) and mechanical parameters (dimensions, mounting type) are identical to the primary part.

Q: Are packaging and handling requirements identical?

A: Both components are supplied in Tape & Reel (TR) packaging. Both carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture control requirements during storage or handling. Packaging and handling procedures are equivalent.

Q: What compliance certifications apply to both parts?

A: Both the CD105NP-330MC and SDR1006-330KL are RoHS3 compliant. Both carry ECCN EAR99 and HTSUS 8504.50.4000 classifications. Compliance status is equivalent for both components.
