Engineering Selection Recommendations

Primary Part (SD6030-180-R): The SD6030-180-R remains the preferred selection for applications requiring the full operating temperature range of -40°C to 125°C and the specified current rating of 1.65 A. This part is in active production status with RoHS compliance and unlimited moisture sensitivity rating, ensuring long-term availability and regulatory compliance.

Substitute Part (CDRH6D38NP-180NC): The CDRH6D38NP-180NC is suitable for applications where the operating temperature maximum does not exceed 100°C and the circuit current demand does not exceed 1.5 A. This substitute offers superior DC resistance characteristics (92 mOhm versus 110 mOhm maximum). The substitute part is ROHS3 compliant and maintains unlimited moisture sensitivity rating. Physical dimensions are slightly larger (6.70 x 6.70 mm footprint, 4.00 mm height versus 6.00 x 6.00 mm footprint, 3.00 mm height), requiring PCB layout verification for mechanical clearance.

Both parts are surface mount inductors with ferrite cores, shielding, and ±30% inductance tolerance, tested at 100 kHz. Selection between primary and substitute parts depends on specific application temperature requirements, current demands, and available PCB space.

Frequently Asked Questions (FAQ)

Q: Can the CDRH6D38NP-180NC replace the SD6030-180-R in all applications?

A: The CDRH6D38NP-180NC is compatible with applications operating at temperatures up to 100°C and requiring current up to 1.5 A. Applications requiring operation at temperatures above 100°C or currents above 1.5 A must use the SD6030-180-R.

Q: What is the inductance tolerance range for both parts?

A: Both the SD6030-180-R and CDRH6D38NP-180NC have ±30% inductance tolerance. For the SD6030-180-R, this yields a range of 11.97 µH to 22.23 µH. For the CDRH6D38NP-180NC, the range is 12.6 µH to 23.4 µH. The nominal values (17.1 µH and 18 µH respectively) fall within acceptable overlap for circuit compatibility.

Q: Are there physical footprint differences between these parts?

A: Yes. The SD6030-180-R has a footprint of 6.00 x 6.00 mm with a maximum seated height of 3.00 mm. The CDRH6D38NP-180NC has a footprint of 6.70 x 6.70 mm with a maximum seated height of 4.00 mm. PCB layout must accommodate the larger dimensions of the substitute part.

Q: Do both parts meet RoHS requirements?

A: Yes. The SD6030-180-R is RoHS Compliant. The CDRH6D38NP-180NC is ROHS3 Compliant. Both meet current regulatory requirements for hazardous substance restrictions.

Q: What is the DC resistance difference between these inductors?

A: The SD6030-180-R has a maximum DC resistance of 110 mOhm. The CDRH6D38NP-180NC has a maximum DC resistance of 92 mOhm. The substitute part exhibits lower resistance, which may reduce power dissipation in the circuit.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both the SD6030-180-R and CDRH6D38NP-180NC are supplied in Tape & Reel (TR) packaging format suitable for automated assembly processes.
