Replacement verdict
Compatible functional replacement candidate
The ADF4159CCPZ and ADF4159CCPZ-RL7 are functionally identical fractional-N frequency synthesizers from Analog Devices, differing only in packaging format (tray vs. tape-and-reel). Both share the same die, electrical specifications, and 5x5 mm LFCSP package, making them fully interchangeable for design and production purposes. The -RL7 variant is simply the reeled option suited for automated SMT assembly, while the base part is supplied in trays.

Key electrical and mechanical differences between the two devices
| Parameter | ADF4159CCPZ | ADF4159CCPZ-RL7 | Why it matters |
|---|---|---|---|
| Manufacturer | Analog Devices Inc. | Analog Devices Inc. | Same manufacturer ensures identical silicon design and process, supporting functional substitutability. |
| Function / Type | 13 GHz fractional-N frequency synthesizer with integrated VCO and modulator | 13 GHz fractional-N frequency synthesizer with integrated VCO and modulator | Identical device function confirms the parts are the same IC and interchangeable in a design. |
| Package / Case | 32-Lead LFCSP (5 mm x 5 mm) | 32-Lead LFCSP (5 mm x 5 mm) | Matching package and footprint allows drop-in replacement on the same PCB layout. |
| Supply Voltage | 3.0 V to 3.6 V (analog and digital) | 3.0 V to 3.6 V (analog and digital) | Same operating voltage range ensures compatibility with the existing power supply design. |
| Frequency Range | Up to 13 GHz RF output | Up to 13 GHz RF output | Identical RF range guarantees the same tuning coverage for the target application. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Same temperature rating ensures equivalent environmental performance and reliability. |
| Packaging / Ordering Format | Tray / cut tape (single-unit or bulk) | Tape and reel (7-inch reel, 1500 units) | The only difference is the shipping format; the -RL7 suffix denotes reel packaging for automated assembly, while the base part is supplied in trays or cut tape. |
| RoHS / Lead-Free Status | RoHS compliant, lead-free | RoHS compliant, lead-free | Both meet the same environmental compliance requirements for production use. |

Frequently asked questions
What is the difference between ADF4159CCPZ and ADF4159CCPZ-RL7?
The ADF4159CCPZ and ADF4159CCPZ-RL7 are the same device (Analog Devices ADF4159, a 13 GHz fractional-N/integer-N PLL frequency synthesizer) in the same 24-lead LFCSP package. The suffix difference denotes packaging format: ADF4159CCPZ is supplied in standard tray or tube packaging, while ADF4159CCPZ-RL7 is supplied in tape-and-reel packaging (7-inch reel) for automated assembly. Electrical performance and die are identical.
Are ADF4159CCPZ and ADF4159CCPZ-RL7 electrically and functionally interchangeable?
Yes. Both order codes refer to the same silicon device with identical electrical specifications, pinout, and package outline. The only difference is the shipping/packaging format, so they are interchangeable in a design provided the assembly process accommodates the respective packaging.
What is the package and pin count for these devices?
Both ADF4159CCPZ and ADF4159CCPZ-RL7 are offered in a 24-lead LFCSP (lead frame chip scale package) with an exposed pad. The package and pinout are identical between the two order codes.
What frequency range does the ADF4159 support?
The ADF4159 is a 13 GHz fractional-N/integer-N frequency synthesizer. Its RF input operates up to 13 GHz, and it includes integrated RF dividers and a phase frequency detector capable of operating at up to 110 MHz, per the Analog Devices datasheet.
Does the packaging format affect moisture sensitivity level (MSL) or handling?
Both order codes use the same package and are rated to the same moisture sensitivity level as specified in the Analog Devices datasheet and packaging information. Tape-and-reel (RL7) and tray/tube formats may differ in dry-pack and reflow handling logistics, but the device MSL rating is a property of the package, not the shipping format.
Which order code should be selected for high-volume automated assembly?
ADF4159CCPZ-RL7 is the tape-and-reel option (7-inch reel), which is typically preferred for automated pick-and-place SMT assembly lines. ADF4159CCPZ in tray/tube format is generally used for prototyping, low-volume, or manual assembly.
Are both order codes RoHS compliant and lead-free?
Both ADF4159CCPZ and ADF4159CCPZ-RL7 are RoHS-compliant, lead-free parts as indicated by the "Z" suffix in the Analog Devices part numbering convention. Confirm the current compliance status against the manufacturer's product page or datasheet before final qualification.
