Substitute Part Grouping Explanation

Substitution of the CD105NP-471KC with the SDR1006-471KL is based on electrical parameter equivalence across the following critical specifications:

Electrical Equivalence Criteria:

• Inductance value: 470 µH (identical)
• Inductance tolerance: ±10% (identical)
• Current rating: 420 mA (identical)
• DC resistance: 1.48Ohm Max (identical)
• Core material: Ferrite (identical)
• Shielding configuration: Unshielded (identical)

Mechanical Compatibility Criteria:

• Mounting type: Surface Mount (identical)
• Package classification: Nonstandard (identical)
• Moisture sensitivity level: 1 (Unlimited) (identical)
• RoHS compliance: ROHS3 Compliant (identical)

Operational Compatibility:

• Inductance test frequency: 1 kHz (identical)
• Both components are Active product status

The SDR1006-471KL qualifies as a direct substitute because all critical electrical parameters match the CD105NP-471KC specifications, ensuring functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the CD105NP-471KC and SDR1006-471KL are Active product status components with full ROHS3 compliance and unlimited moisture sensitivity rating, making them suitable for production environments with standard handling protocols. The SDR1006-471KL offers an extended operating temperature range of -40°C to 125°C compared to the CD105NP-471KC range of -40°C to 100°C, providing additional thermal margin in applications approaching the upper temperature limit. Selection between these components should be based on inventory availability, supply chain lead times, and specific thermal requirements of the application. Both components meet identical electrical specifications for inductance, current rating, and DC resistance, ensuring direct functional substitution in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the SDR1006-471KL replace the CD105NP-471KC in existing designs?

A: Yes. Both components share identical electrical specifications: 470 µH inductance, ±10% tolerance, 420 mA current rating, and 1.48Ohm maximum DC resistance. Both are unshielded ferrite core inductors with surface mount configuration and nonstandard package classification.

Q: What are the physical dimension differences between these parts?

A: The CD105NP-471KC measures 0.394" L x 0.354" W (10.00mm x 9.00mm) with a maximum seated height of 0.228" (5.80mm). The SDR1006-471KL measures 0.386" L x 0.386" W (9.80mm x 9.80mm) with an identical maximum seated height of 0.228" (5.80mm). Both components have nonstandard package dimensions and should be verified for PCB layout compatibility.

Q: Are there temperature rating differences that affect substitution?

A: The CD105NP-471KC operates from -40°C to 100°C, while the SDR1006-471KL operates from -40°C to 125°C. The SDR1006-471KL provides a 25°C higher upper temperature limit, which may be advantageous in thermally demanding applications but does not restrict substitution in designs operating within the CD105NP-471KC temperature range.

Q: Do both parts have identical compliance certifications?

A: Yes. Both components are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements. Both are classified under ECCN EAR99 and HTSUS 8504.50.4000.

Q: What is the difference between the core types listed?

A: The CD105NP-471KC is specified as a ferrite core inductor. The SDR1006-471KL is specified as a drum core, wirewound inductor with ferrite material. Both use ferrite core material and deliver identical electrical performance at the specified test frequency of 1 kHz.

Q: Are packaging formats identical?

A: Yes. Both components are supplied in Tape & Reel (TR) packaging format, suitable for automated assembly processes.
