Engineering Selection Recommendations

Primary Selection: CD105NP-151KC

The CD105NP-151KC remains the primary component choice when specified in original designs. This part maintains Active product status with established supply chain availability (809 Pcs in stock) and full ROHS3 compliance certification.

Substitute Selection: SDR1006-151KL

The SDR1006-151KL by Bourns Inc. is a qualified substitute when CD105NP-151KC availability is constrained. This part demonstrates:

• Identical electrical performance across all critical parameters (inductance, current rating, DC resistance)
• Equivalent mechanical compatibility (surface mount, identical seated height)
• Enhanced operating temperature range (-40°C ~ 125°C vs. -40°C ~ 100°C)
• Full ROHS3 compliance and unlimited moisture sensitivity rating
• Higher inventory availability (4614 Pcs in stock)
• REACH Unaffected status

Both parts carry EAR99 ECCN classification and 8504.50.4000 HTSUS code, confirming regulatory equivalence for export and import purposes.

Frequently Asked Questions (FAQ)

Q: Can SDR1006-151KL replace CD105NP-151KC in existing circuit designs?

A: Yes. The SDR1006-151KL meets all electrical and mechanical specifications required for direct substitution. Inductance value, current rating, DC resistance, core material, shielding configuration, and physical dimensions are equivalent. No circuit redesign is required.

Q: What are the dimensional differences between these parts?

A: The CD105NP-151KC measures 10.00mm L x 9.00mm W x 5.80mm H (seated). The SDR1006-151KL measures 9.80mm L x 9.80mm W x 5.80mm H (seated). Both parts have identical seated height. The length and width differences are within typical PCB layout tolerances for surface mount components.

Q: Are there temperature range considerations when substituting?

A: The SDR1006-151KL operates across -40°C ~ 125°C, providing a 25°C extended upper temperature limit compared to the CD105NP-151KC (-40°C ~ 100°C). For applications operating within the CD105NP-151KC range, this difference is not a limiting factor. For applications approaching 100°C, the substitute part provides additional thermal margin.

Q: Do both parts have identical RoHS and compliance certifications?

A: Yes. Both the CD105NP-151KC and SDR1006-151KL are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). Both carry EAR99 ECCN classification. The SDR1006-151KL additionally carries REACH Unaffected status.

Q: What is the difference between the CD105 and SDR1006 series designations?

A: CD105 is the Sumida series designation; SDR1006 is the Bourns series designation. These are manufacturer-specific series identifiers. The functional and electrical characteristics are equivalent for the specified part numbers.

Q: Can these parts be used interchangeably in high-frequency applications?

A: Both parts are specified for 1 kHz inductance testing. The CD105NP-151KC has a self-resonant frequency of 5.86MHz; the SDR1006-151KL has a self-resonant frequency of 4.5MHz. For applications operating below these frequencies, both parts are suitable. Application-specific frequency response requirements should be evaluated against these specifications.
