Replacement verdict
Compatible functional replacement candidate
The ADF4169CCPZ and ADF4169CCPZ-RL7 are the same ADF4169 fractional-N PLL synthesizer device offered in different packaging formats: the ADF4169CCPZ is supplied in a tube/tray, while the ADF4169CCPZ-RL7 is the tape-and-reel variant. Both share identical electrical, functional, and package specifications, making them functionally interchangeable for design and qualification purposes. The only meaningful distinction is the shipping/packaging format, which affects handling and automated assembly rather than device performance.

Key electrical and mechanical differences between the two devices
| Parameter | ADF4169CCPZ | ADF4169CCPZ-RL7 | Why it matters |
|---|---|---|---|
| Manufacturer | Analog Devices Inc. | Analog Devices Inc. | Same manufacturer ensures identical silicon design and process, critical for functional substitutability. |
| Function / Type | Fractional-N / Integer-N PLL Frequency Synthesizer with integrated VCO | Fractional-N / Integer-N PLL Frequency Synthesizer with integrated VCO | Identical device function confirms the parts are the same IC and directly interchangeable in a design. |
| Frequency Range | Up to 13.5 GHz RF output | Up to 13.5 GHz RF output | Matching frequency range ensures the part meets the same RF tuning requirements in the target application. |
| Package / Case | 32-Lead LFCSP (5 mm x 5 mm) | 32-Lead LFCSP (5 mm x 5 mm) | Same package and footprint allow drop-in replacement without PCB layout changes. |
| Supply Voltage | 3.0 V to 3.6 V (analog/digital), VCO supply 3.0 V to 3.6 V | 3.0 V to 3.6 V (analog/digital), VCO supply 3.0 V to 3.6 V | Identical supply requirements mean the same power rail design works for either part. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Same temperature rating ensures equivalent environmental performance and reliability. |
| Packaging / Delivery Form | Tray / cut tape (individual or small quantities) | Tape and reel (7-inch reel, 1500 units) | The only difference is the shipping form; -RL7 denotes reel packaging for automated high-volume assembly, while the base part is typically supplied in trays or cut tape. |
| Moisture Sensitivity Level (MSL) | MSL 3 | MSL 3 | Same MSL dictates identical handling, storage, and reflow bake requirements. |
| RoHS Compliance | RoHS compliant | RoHS compliant | Both meet the same environmental compliance standard, avoiding regulatory substitution issues. |

Frequently asked questions
What is the difference between ADF4169CCPZ and ADF4169CCPZ-RL7?
The ADF4169CCPZ and ADF4169CCPZ-RL7 are the same device, the ADF4169 microwave fractional-N/integer-N PLL synthesizer from Analog Devices, in the same 24-lead LFCSP package. The suffix difference is packaging format: ADF4169CCPZ is supplied in trays, while ADF4169CCPZ-RL7 is supplied in tape-and-reel (7-inch reel) for automated assembly. Electrical and functional specifications are identical.
Are ADF4169CCPZ and ADF4169CCPZ-RL7 electrically and functionally interchangeable?
Yes. Both order codes refer to the same silicon die and package (24-lead LFCSP, 4 mm × 4 mm), so RF performance, frequency range, phase noise, and register map are identical. The only difference is the shipping container (tray vs. 7-inch tape-and-reel), so they are interchangeable in a design provided the assembly process matches the chosen packaging.
What frequency range does the ADF4169 support?
The ADF4169 is specified for RF output up to 13.5 GHz, with the integrated VCO covering the microwave band and the fractional-N divider allowing fine frequency resolution. Designers should confirm the exact output range and divider configuration against the Analog Devices ADF4169 datasheet for their target band.
What is the difference between fractional-N and integer-N modes on the ADF4169?
The ADF4169 supports both fractional-N and integer-N operation. Fractional-N mode enables finer frequency resolution and faster lock times by allowing a fractional modulus in the feedback divider, while integer-N mode provides lower phase noise and spurious content in applications where channel spacing permits. Mode selection is configured through the device's register settings.
What package and pin count do ADF4169CCPZ and ADF4169CCPZ-RL7 use?
Both parts use the 24-lead LFCSP (lead frame chip scale package) with an exposed pad, measuring 4 mm × 4 mm. The exposed pad must be soldered to the PCB ground plane for thermal and RF performance. Pin assignments are identical between the two order codes.
Which packaging option should be selected for high-volume production?
For automated pick-and-place assembly lines, ADF4169CCPZ-RL7 (7-inch tape-and-reel) is the appropriate choice because it is compatible with standard SMT feeders. ADF4169CCPZ (tray) is typically used for prototyping, low-volume runs, or manual assembly. Both contain the same device.
What supply voltage and interface does the ADF4169 require?
The ADF4169 operates from a nominal 3.3 V supply for the analog and digital sections, with a separate charge pump supply that can be set for the VCO tuning range. It is programmed via a 3-wire SPI-compatible serial interface (CLK, DATA, LE). Verify exact supply limits and current consumption in the Analog Devices datasheet before finalizing the power design.
Are ADF4169CCPZ and ADF4169CCPZ-RL7 RoHS compliant?
Both order codes are supplied in RoHS-compliant, lead-free packaging as part of Analog Devices' standard Pb-free portfolio. Customers should confirm the current compliance status and any exemptions on the Analog Devices product page or the manufacturer's material declaration before final qualification.
