Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CD105-101KC are classified based on strict electrical and mechanical parameter alignment:

Direct Substitution Criteria:

• Inductance value: 100 µH (±10% tolerance acceptable)
• Current rating: 970 mA minimum
• DC resistance: 350 mOhm maximum
• Shielding configuration: Unshielded
• Mounting type: Surface Mount
• Physical footprint compatibility: 10.00mm x 9.00mm x 5.80mm maximum

Substitute Classification:

Direct Manufacturer Equivalent (CD105NP-101KC): Identical electrical specifications and physical dimensions from the same manufacturer series. Differs only in packaging format (Tape & Reel) and product status (Active vs. Obsolete). RoHS3 compliance provides regulatory advantage.

Similar Cross-Manufacturer Substitute (PG0015.104NLT): Meets all critical electrical parameters (100 µH, 970 mA, 350 mOhm DCR) with compatible physical dimensions. Differs in core material type (wirewound vs. ferrite), inductance tolerance (±20% vs. ±10%), and operating temperature maximum (125°C vs. 100°C). Self-resonant frequency differs (6.2 MHz vs. 7.64 MHz).

Parameter Comparison

Engineering Selection Recommendations

CD105NP-101KC (Recommended Primary Substitute):

This part is the optimal substitute for CD105-101KC applications. It maintains identical electrical specifications (100 µH, 970 mA, 350 mOhm DCR) and physical dimensions, ensuring direct functional equivalence. The primary advantages are active product status, ensuring long-term availability, and ROHS3 compliance, which satisfies current regulatory requirements. The packaging format change from bulk to Tape & Reel (TR) provides improved handling and automated assembly compatibility. Selection of this part eliminates obsolescence risk while maintaining design performance.

PG0015.104NLT (Secondary Substitute):

This part provides electrical compatibility with acceptable trade-offs. It meets the critical parameters of inductance (100 µH), current rating (970 mA), and DC resistance (350 mOhm). Physical dimensions are marginally larger (10.15mm x 9.15mm x 5.55mm) but remain compatible with standard nonstandard package footprints. The inductance tolerance is wider (±20% vs. ±10%), which may require circuit validation in applications with tight tolerance requirements. The extended operating temperature range (-40°C to 125°C) provides thermal margin beyond the original specification. The self-resonant frequency difference (6.2 MHz vs. 7.64 MHz) should be evaluated for high-frequency applications. This part is suitable when CD105NP-101KC availability is constrained and circuit performance permits the specified parameter variations.

Frequently Asked Questions (FAQ)

Q: Can CD105NP-101KC be used as a direct replacement for CD105-101KC?

A: Yes. CD105NP-101KC is a direct functional equivalent. It provides identical inductance (100 µH), current rating (970 mA), DC resistance (350 mOhm), and physical dimensions. The only differences are packaging format (Tape & Reel vs. bulk) and product status (Active vs. Obsolete). No circuit modifications are required.

Q: What are the key differences between CD105NP-101KC and PG0015.104NLT?

A: Both parts meet the core electrical requirements (100 µH, 970 mA, 350 mOhm). The primary differences are: (1) Core material: ferrite vs. wirewound construction; (2) Inductance tolerance: ±10% vs. ±20%; (3) Operating temperature maximum: 100°C vs. 125°C; (4) Self-resonant frequency: 7.64 MHz vs. 6.2 MHz; (5) Physical dimensions: identical footprint with minor height variation (5.80mm vs. 5.55mm).

Q: Is PG0015.104NLT suitable for all applications using CD105-101KC?

A: PG0015.104NLT is suitable for most applications but requires evaluation in circuits with tight inductance tolerance requirements or high-frequency operation above 6.2 MHz. The wider tolerance (±20%) and lower self-resonant frequency may impact performance in precision filtering or high-frequency switching applications. Thermal applications requiring operation above 100°C benefit from the extended temperature range.

Q: What is the impact of the packaging change from bulk to Tape & Reel?

A: Tape & Reel (TR) packaging improves automated assembly compatibility and reduces handling damage risk compared to bulk packaging. For manual assembly or low-volume applications, this change has minimal impact. For production environments utilizing pick-and-place equipment, Tape & Reel packaging is advantageous.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both CD105NP-101KC and PG0015.104NLT are ROHS3 compliant. The original CD105-101KC is RoHS non-compliant. Selection of either substitute part satisfies current RoHS regulatory requirements.

Q: Can physical dimensions affect PCB layout compatibility?

A: The substitute parts have compatible physical dimensions within standard nonstandard package tolerances. CD105NP-101KC is dimensionally identical (10.00mm x 9.00mm x 5.80mm). PG0015.104NLT is marginally larger in length and width (10.15mm x 9.15mm) but slightly shorter in height (5.55mm). PCB layouts designed for the original part accommodate both substitutes without modification.

Q: Which substitute part should be selected for new designs?

A: CD105NP-101KC is the recommended selection for new designs. It provides identical performance to the original part with the advantage of active product status and regulatory compliance. PG0015.104NLT is suitable as a secondary option when CD105NP-101KC availability is limited and circuit requirements permit the specified parameter variations.
