Replacement verdict
Compatible functional replacement candidate
The ADF4360-2BCPZ and ADF4360-2BCP are functionally equivalent integrated synthesizers sharing the same core PLL and VCO architecture, frequency range, and 24-lead LFCSP footprint. The only material distinction is the package finish, where the BC PZ suffix denotes RoHS-compliant lead-free plating versus the standard finish of the BCP variant. Designers can treat these parts as interchangeable for new and existing designs, provided the assembly process and compliance requirements accept the lead-free package option.

Frequently asked questions
What is the difference between the ADF4360-2BCPZ and the ADF4360-2BCP?
The ADF4360-2BCPZ and ADF4360-2BCP are functionally identical integrated synthesizers and VCOs; the only difference is the package finish. The "Z" suffix in ADF4360-2BCPZ denotes a RoHS-compliant, lead-free (Pb-free) package, whereas the ADF4360-2BCP is the non-RoHS, lead-containing version. Both are supplied in a 24-lead LFCSP package.
Are the ADF4360-2BCPZ and ADF4360-2BCP electrically and functionally interchangeable?
Yes. Both devices share the same silicon die, the same 24-lead LFCSP footprint, and the same pinout and electrical specifications. The ADF4360-2BCPZ can be used in place of the ADF4360-2BCP in existing designs without changes to the PCB layout or external circuitry, provided the assembly process supports Pb-free soldering.
What is the frequency range of the ADF4360-2 integrated VCO?
The ADF4360-2 is specified for an output frequency range of 1850 MHz to 2170 MHz, with a center frequency of approximately 2000 MHz. The internal VCO is divided by 2 to provide the final RF output, and the device includes a programmable dual-modulus prescaler and a 24-bit fractional-N or integer-N synthesizer.
What supply voltage and current does the ADF4360-2 require?
The ADF4360-2 operates from a single 3.0 V to 3.6 V supply. Typical current consumption is approximately 25 mA for the VCO and synthesizer combined, with additional current for the RF output stage depending on the programmed output power level.
Does the ADF4360-2BCPZ meet RoHS requirements while the ADF4360-2BCP does not?
Correct. The ADF4360-2BCPZ is the RoHS-compliant, Pb-free variant and is suitable for designs requiring compliance with the RoHS directive. The ADF4360-2BCP contains lead in its package finish and is not RoHS-compliant. Designers should select the "Z" version for new designs and for markets with lead-free regulatory requirements.
What is the recommended package and PCB land pattern for these devices?
Both the ADF4360-2BCPZ and ADF4360-2BCP use a 24-lead LFCSP (lead frame chip scale package) with an exposed paddle. The exposed paddle should be soldered to a ground plane with thermal vias for adequate heat dissipation and RF grounding. The land pattern is identical for both variants.
Can the ADF4360-2BCPZ and ADF4360-2BCP be mixed on the same assembly line?
They can be used on the same assembly line, but the soldering profile must be compatible with the Pb-free finish of the ADF4360-2BCPZ. If the line uses a leaded solder process for the ADF4360-2BCP, a separate Pb-free reflow profile is required for the ADF4360-2BCPZ to ensure reliable solder joints.
