Replacement verdict
Compatible functional replacement candidate
The AD8302ARUZ-RL7 and AD8302ARUZ are functionally equivalent RF gain and phase detectors from Analog Devices, sharing the same die, TSSOP-14 package, and full electrical specifications. The only distinction is packaging format: the -RL7 suffix denotes tape-and-reel shipment, while the base part is supplied in standard tube or tray format. Either part can serve as a direct drop-in replacement for the other in the same PCB footprint, with selection driven solely by assembly and inventory handling preferences.

Key electrical and mechanical differences between the two devices
| Parameter | AD8302ARUZ-RL7 | AD8302ARUZ | Why it matters |
|---|---|---|---|
| Function | RF/IF Gain and Phase Detector | RF/IF Gain and Phase Detector | Both parts perform the same core function, so they are functionally interchangeable in the same circuit role. |
| Frequency Range | LF to 2.7 GHz | LF to 2.7 GHz | The operating frequency range must cover the application's signal band for the detector to work correctly. |
| Package / Case | 16-Lead TSSOP | 16-Lead TSSOP | Identical package ensures the same PCB footprint and assembly process can be used. |
| Supply Voltage | 2.7 V to 5.5 V | 2.7 V to 5.5 V | The supply range must match the system rail to avoid damage or insufficient operation. |
| Supply Current | ~19 mA typical | ~19 mA typical | Current draw affects power budget and thermal design; matching values confirm equivalent loading. |
| Gain Measurement Range | ±30 dB | ±30 dB | The gain detection range determines the dynamic range over which the part can measure signal amplitude differences. |
| Phase Measurement Range | 0° to 180° | 0° to 180° | Phase detection range defines the angular span over which phase differences can be measured. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +85°C | The temperature range must suit the target environment for reliable operation. |
| Packaging / Ordering Format | Tape & Reel (RL7) | Tube / Tray | The ordering format affects how the part is supplied for automated assembly versus manual or low-volume use, though the die is identical. |

Frequently asked questions
What is the difference between AD8302ARUZ-RL7 and AD8302ARUZ?
Both parts are the same AD8302 RF/IF gain and phase detector die in a 14-lead TSSOP package. The AD8302ARUZ is the standard tube/rail packaging option, while the AD8302ARUZ-RL7 is the tape-and-reel packaging option (7-inch reel, 1,000 pieces per reel). The electrical specifications and functional performance are identical; only the shipping/packaging format differs.
Are AD8302ARUZ-RL7 and AD8302ARUZ electrically and functionally interchangeable?
Yes. Both order codes refer to the same AD8302 device in the 14-lead TSSOP (RU-14) package, so they share the same datasheet specifications, pinout, and operating characteristics. The only difference is the packaging format (tape-and-reel vs. standard rail/tube), so they are interchangeable in a design provided the assembly process accommodates the respective packaging.
What are the key specifications of the AD8302?
The AD8302 is a fully integrated RF/IF gain and phase detector operating from DC to 2.7 GHz. It provides a gain measurement range of ±30 dB and a phase measurement range of 0° to 180°, with a gain scaling of 30 mV/dB and a phase scaling of 10 mV/degree. It operates from a single 2.7 V to 5.5 V supply and is specified over the −40°C to +85°C temperature range.
What package does the AD8302ARUZ use, and is it RoHS compliant?
The AD8302ARUZ and AD8302ARUZ-RL7 are supplied in a 14-lead TSSOP package (RU-14). The "Z" suffix in the order code denotes a RoHS-compliant, lead-free package per Analog Devices' ordering nomenclature.
How many units are in the AD8302ARUZ-RL7 reel compared with the AD8302ARUZ?
The AD8302ARUZ-RL7 is supplied on a 7-inch tape-and-reel with 1,000 pieces per reel. The AD8302ARUZ is supplied in standard rail/tube packaging; the exact quantity per rail should be confirmed on the Analog Devices datasheet or distributor packaging specification.
Can I use the AD8302ARUZ-RL7 in an automated pick-and-place assembly line?
Yes. The -RL7 tape-and-reel format is intended for automated surface-mount assembly. The AD8302ARUZ in rail/tube packaging can also be used with automated placement equipment that supports tube feeders, but tape-and-reel is generally preferred for high-volume SMT production.
Do both order codes share the same operating temperature range and supply voltage?
Yes. Since both are the same AD8302 device, they share the same specified operating temperature range of −40°C to +85°C and the same single-supply operating range of 2.7 V to 5.5 V, as documented in the Analog Devices AD8302 datasheet.
