Replacement verdict
Compatible functional replacement candidate
The AD8367ARUZ-RL7 and AD8367ARU are functionally equivalent variable gain amplifier ICs sharing the same core die, package, and electrical specifications; the only distinction is the tape-and-reel packaging format of the RL7 variant versus the tube format of the standard ARU. Either part can serve as a direct functional substitute for the other in 800 MHz VGA applications, with the choice driven by assembly line packaging requirements rather than electrical performance.

Frequently asked questions
What is the difference between AD8367ARUZ-RL7 and AD8367ARU?
Both parts are the same AD8367 500 MHz, 45 dB linear-in-dB variable gain amplifier (VGA) from Analog Devices in a 20-lead TSSOP package. The AD8367ARUZ-RL7 is the RoHS-compliant (Z) version supplied in tape-and-reel packaging (RL7, 7-inch reel), while AD8367ARU is the non-RoHS tube/rail version. The silicon die and electrical specifications are identical.
Are AD8367ARUZ-RL7 and AD8367ARU electrically and functionally interchangeable?
Yes. Both variants share the same datasheet specifications for the AD8367, including a -3 dB bandwidth of 500 MHz, a gain range of -2.5 dB to +42.5 dB, 45 dB/V gain slope, and operation from a single 5 V supply. The only differences are RoHS compliance and packaging format, so they are functionally interchangeable in the same PCB footprint.
Do AD8367ARUZ-RL7 and AD8367ARU use the same package and pinout?
Yes. Both are offered in the 20-lead TSSOP (RU-20) package with identical pin assignments, including the gain-control pin (GAIN), input (INHI/INLO), output (VOUT), and supply/ground pins. The PCB land pattern is the same for both orderable part numbers.
What is the difference between the RL7 and non-RL7 suffixes on these AD8367 parts?
The RL7 suffix denotes tape-and-reel packaging (7-inch reel) for automated assembly, while the absence of a reel suffix indicates the standard tube/rail packaging. The "Z" in AD8367ARUZ-RL7 indicates RoHS compliance; AD8367ARU is the non-RoHS version. Electrical performance is unaffected by these suffixes.
Can AD8367ARU be used as a drop-in replacement for AD8367ARUZ-RL7 in a RoHS-compliant design?
Electrically and mechanically yes, but AD8367ARU is not RoHS-compliant, so substituting it into a RoHS-compliant product would violate RoHS compliance. For RoHS-restricted designs, AD8367ARUZ-RL7 (or another Z-suffix variant) should be used instead.
What are the key performance specifications shared by AD8367ARUZ-RL7 and AD8367ARU?
Both parts provide a 500 MHz -3 dB bandwidth, a 45 dB linear-in-dB gain range from -2.5 dB to +42.5 dB, a gain slope of 45 dB/V, and operate from a single 5 V supply. They also feature an on-chip square-law detector for AGC applications and are specified over the -40 °C to +85 °C temperature range.
Which part number should be ordered for high-volume automated assembly?
AD8367ARUZ-RL7 is the appropriate choice for high-volume automated pick-and-place assembly because the RL7 suffix indicates tape-and-reel packaging. AD8367ARU is supplied in tubes/rails, which are typically used for prototyping or low-volume manual assembly.
