CD105NP-560KC Equivalent & Substitute Parts

Part Overview

The CD105NP-560KC is a 56 µH unshielded surface mount inductor manufactured by Sumida America Components Inc. This fixed inductor is designed for applications requiring moderate inductance values with a current rating of 1.17 A and a maximum DC resistance of 190mOhm. The component features a ferrite core construction and operates across the temperature range of -40°C to 100°C. As an active product with ROHS3 compliance and unlimited moisture sensitivity rating, the CD105NP-560KC serves as a primary selection for circuit designs requiring stable inductance characteristics. Equivalent substitutes are identified to provide alternative sourcing options when primary inventory is unavailable or when design specifications permit component interchange.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD105NP-560KC is determined by strict equivalence across the following critical parameters:

Inductance Value: Both the main part and substitute must maintain 56 µH with ±10% tolerance to ensure circuit performance consistency.

Current Rating: The substitute current rating must meet or exceed the 1.17 A requirement of the primary component to prevent thermal stress and component failure.

DC Resistance: Maximum DC resistance of 190mOhm establishes the upper limit for power dissipation characteristics. Substitutes must not exceed this specification.

Core Material: Ferrite core construction is required to maintain inductance stability and frequency response characteristics across the operating temperature range.

Shielding Configuration: Unshielded construction must be preserved to maintain electromagnetic coupling characteristics in the target application.

Mounting Type: Surface mount technology is mandatory for PCB assembly compatibility.

Environmental Compliance: ROHS3 compliance is required for regulatory adherence in target markets.

The SDR1006-560KL from Bourns Inc. meets all substitution criteria within these defined parameters.

Parameter Comparison

Engineering Selection Recommendations

The SDR1006-560KL qualifies as a direct substitute for the CD105NP-560KC based on electrical parameter equivalence and regulatory compliance alignment. Both components maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols.

The substitute component demonstrates equivalent inductance, tolerance, DC resistance, and core material specifications. The current rating differential of 0.02 A (1.15 A versus 1.17 A) represents a 1.7% reduction and remains within acceptable engineering margins for most applications operating below maximum rated current.

The extended operating temperature range of the SDR1006-560KL (-40 to 125°C versus -40 to 100°C) provides additional thermal margin without introducing incompatibility concerns. The dimensional variance of 0.2 mm in length and 0.1 mm in width falls within typical PCB layout tolerances for nonstandard surface mount packages.

Both components are active products with established supply chains, supporting long-term design continuity and procurement reliability.

Frequently Asked Questions (FAQ)

Q: Can the SDR1006-560KL replace the CD105NP-560KC in existing designs?

A: Yes. The SDR1006-560KL meets all critical electrical parameters: 56 µH inductance, ±10% tolerance, 190mOhm maximum DC resistance, and ferrite core construction. Both components are unshielded surface mount inductors with equivalent height and moisture sensitivity ratings.

Q: What is the significance of the 0.02 A current rating difference?

A: The SDR1006-560KL is rated at 1.15 A compared to the CD105NP-560KC at 1.17 A. This 1.7% difference is negligible for applications operating below maximum rated current. Applications requiring the full 1.17 A rating should verify the substitute's saturation current specification (2.1 A for the SDR1006-560KL) to confirm adequate thermal headroom.

Q: Are there dimensional compatibility concerns?

A: The SDR1006-560KL measures 9.80 x 9.80 mm compared to the CD105NP-560KC at 10.00 x 9.00 mm. Both share identical 5.80 mm maximum seated height. The 0.2 mm length reduction and 0.1 mm width increase are within standard PCB layout tolerances for nonstandard packages. Verify footprint compatibility with your specific PCB design.

Q: Do both components meet the same environmental standards?

A: Yes. Both the CD105NP-560KC and SDR1006-560KL are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating. Both carry EAR99 export classification and 8504.50.4000 HTSUS coding.

Q: What is the difference in self-resonant frequency between these components?

A: The CD105NP-560KC has a self-resonant frequency of 10.2 MHz, while the SDR1006-560KL is rated at 7.5 MHz. This difference reflects different core and winding geometries. For applications sensitive to high-frequency behavior, verify that the 7.5 MHz specification of the substitute remains acceptable for your circuit's operating frequency range.

Q: Can I use the SDR1006-560KL in applications requiring the full -40 to 100°C temperature range?

A: Yes. The SDR1006-560KL operates across -40 to 125°C, which encompasses the -40 to 100°C requirement of the CD105NP-560KC. The extended upper temperature limit of the substitute provides additional thermal margin without introducing incompatibility.
