Engineering Selection Recommendations

CD105NP-101KC (Sumida America Components Inc.)

Primary selection when Sumida supply chain is preferred. Active product status with confirmed inventory of 1511 pieces. Full RoHS3 compliance and EAR99 classification. Operating temperature range -40°C to 100°C meets standard industrial requirements.

SDR1006-101KL (Bourns Inc.)

Direct substitute with equivalent electrical and mechanical specifications. Active product status with higher inventory availability (6000 pieces). Extended operating temperature range to 125°C provides additional thermal margin. Identical RoHS3 compliance, MSL rating, and regulatory classification. Dimensional compatibility confirmed with maximum seated height of 5.80mm matching the original component. Selection of this substitute is based on regulatory equivalence, product status alignment, and compliance certifications.

Both components satisfy the CD105NP-101KC substitution criteria and are suitable for direct replacement in applications requiring 100 µH inductance at 970 mA current rating with 350 mOhm maximum DC resistance.

Frequently Asked Questions (FAQ)

Q: What electrical parameters must match for substitution of the CD105NP-101KC?

A: The substitute must provide 100 µH inductance at ±10% tolerance, support 970 mA current rating, and maintain 350 mOhm maximum DC resistance. Core material must be ferrite with unshielded configuration.

Q: Are dimensional differences between CD105NP-101KC and SDR1006-101KL acceptable?

A: Yes. The CD105NP-101KC measures 10.00mm L x 9.00mm W, while the SDR1006-101KL measures 9.80mm L x 9.80mm W. Both components share identical seated height of 5.80mm maximum. These dimensional variations are compatible within the nonstandard package classification for surface mount applications.

Q: Does the SDR1006-101KL substitute maintain RoHS3 compliance?

A: Yes. The SDR1006-101KL is ROHS3 compliant with MSL 1 rating, matching the original CD105NP-101KC specifications.

Q: What is the temperature operating range difference between these components?

A: The CD105NP-101KC operates from -40°C to 100°C. The SDR1006-101KL extends the upper limit to 125°C. Both meet or exceed the original component's temperature requirements.

Q: Can the SDR1006-101KL be used in applications designed for CD105NP-101KC?

A: Yes. The SDR1006-101KL satisfies all critical electrical specifications, mechanical compatibility, and regulatory requirements specified for the CD105NP-101KC, enabling direct substitution.

Q: Are there packaging differences between these inductors?

A: Both components are supplied in Tape & Reel (TR) packaging and classified as nonstandard package types. Packaging format is equivalent for automated assembly processes.
