Frequently Asked Questions (FAQ)

Q: Can SDR0604-560KL replace CD54NP-560KC in existing designs?

A: Yes. Both inductors provide identical inductance (56 µH ±10%), current rating (680 mA), and DC resistance (420 mOhm max). Surface mount packaging and ferrite core construction are equivalent. Physical dimensions are compatible within nonstandard package specifications.

Q: What are the dimensional differences between these parts?

A: CD54NP-560KC measures 0.228" L x 0.205" W x 0.191" H (5.80mm x 5.20mm x 4.85mm). SDR0604-560KL measures 0.228" L x 0.228" W x 0.189" H (5.80mm x 5.80mm x 4.80mm). The width dimension differs by 0.023" (0.60mm), and height differs by 0.002" (0.05mm). PCB layout verification is required for width accommodation.

Q: Are there temperature rating differences?

A: CD54NP-560KC operates from -40°C to 100°C. SDR0604-560KL operates from -40°C to 125°C. If application requires operation above 100°C, SDR0604-560KL provides extended thermal capability.

Q: Do both parts have identical RoHS compliance?

A: Yes. Both CD54NP-560KC and SDR0604-560KL are ROHS3 compliant with MSL rating of 1 (Unlimited). SDR0604-560KL additionally carries REACH Unaffected designation.

Q: What is the inductance test frequency for each part?

A: CD54NP-560KC inductance is tested at 2.52 MHz. SDR0604-560KL inductance is tested at 1 kHz. Both maintain ±10% tolerance across their respective test frequencies.

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

A: SDR0604-560KL provides additional performance data: Q factor of 22 @ 2.52 MHz and self-resonant frequency of 11 MHz. This information supports high-frequency circuit analysis. CD54NP-560KC does not provide Q factor or self-resonant frequency specifications.
