Substitute Part Grouping Explanation

Substitution of the CD105NP-561KC with the SDR1006-561KL is based on electrical and mechanical parameter equivalence. Both parts share identical core electrical specifications: 560 µH inductance at ±10% tolerance, 330 mA current rating, and 1.9 Ohm maximum DC resistance. Both components are unshielded ferrite core inductors with surface mount configuration and nonstandard package dimensions. Physical dimensions are comparable (CD105NP: 10.00mm × 9.00mm × 5.80mm; SDR1006: 9.80mm × 9.80mm × 5.80mm), permitting direct PCB layout compatibility. Both parts carry RoHS3 compliance and MSL Level 1 moisture sensitivity rating. The SDR1006-561KL features a drum core wirewound construction type, which does not affect functional equivalence for the specified electrical parameters. Substitution is valid when the application does not impose constraints on core construction type or frequency response characteristics beyond the provided specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the CD105NP-561KC and SDR1006-561KL are Active product status components with full RoHS3 compliance and ECCN EAR99 classification. Selection between these parts is determined by application-specific requirements and supply availability. The CD105NP-561KC is the primary specified component and should be used when available and when design validation has been performed against this specific part number. The SDR1006-561KL serves as a direct electrical equivalent and may be selected when the CD105NP-561KC is unavailable, provided that PCB layout accommodates the minor dimensional variation (9.80mm × 9.80mm versus 10.00mm × 9.00mm). The SDR1006-561KL offers an extended operating temperature range to 125°C, which may provide additional margin in high-temperature applications. Both parts are suitable for tape and reel packaging in production environments. Component selection should be documented in design change notices when substitution occurs.

Frequently Asked Questions (FAQ)

Q: Can the SDR1006-561KL be used as a direct replacement for the CD105NP-561KC on existing PCBs?

A: The SDR1006-561KL is electrically equivalent and physically compatible with the CD105NP-561KC. The package dimensions are comparable (9.80mm × 9.80mm × 5.80mm versus 10.00mm × 9.00mm × 5.80mm), and both components use identical mounting footprints for surface mount assembly. Direct PCB substitution is permissible without layout modification.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution is valid when the following parameters match: inductance value (560 µH), inductance tolerance (±10%), current rating (330 mA), DC resistance (1.9 Ohm maximum), core material (ferrite), shielding type (unshielded), and mounting configuration (surface mount). Both parts meet these criteria.

Q: Does the difference in core construction type (standard ferrite versus drum core wirewound) affect performance?

A: The core construction type difference does not affect the specified electrical parameters provided in this reference. Both parts deliver identical inductance, current rating, and DC resistance. Applications with specific frequency response or Q-factor requirements should reference the detailed frequency characteristics provided by each manufacturer.

Q: Are there temperature range considerations when selecting between these parts?

A: The CD105NP-561KC operates from -40°C to 100°C, while the SDR1006-561KL extends to 125°C. For applications requiring operation above 100°C, the SDR1006-561KL provides additional thermal margin. For standard temperature range applications, both parts are equivalent.

Q: What compliance certifications apply to both parts?

A: Both the CD105NP-561KC and SDR1006-561KL carry RoHS3 compliance, MSL Level 1 rating (unlimited moisture sensitivity), and ECCN EAR99 classification. Both are suitable for commercial and industrial applications requiring environmental compliance documentation.
