Replacement verdict
Compatible functional replacement candidate
The AD7302BRZ and AD7302BR-REEL are functionally equivalent dual 8-bit voltage-output DACs sharing the same silicon die, package, and electrical specifications; the only distinction is the delivery format, with the REEL variant supplied on tape and reel for automated assembly. Either part number can be used interchangeably in the same design, with selection driven by production packaging requirements rather than electrical or functional differences.

Key electrical and mechanical differences between the two devices
| Parameter | AD7302BRZ | AD7302BR-REEL | Why it matters |
|---|---|---|---|
| Number of DAC Channels | 2 | 2 | Determines how many independent analog outputs the device can drive; must match for functional substitutability. |
| Resolution | 8 bits | 8 bits | Sets the output voltage step size and achievable precision; identical resolution ensures equivalent output granularity. |
| Supply Voltage Range | 2.7 V to 5.5 V | 2.7 V to 5.5 V | Defines the operating voltage window; matching ranges allow drop-in use in the same power rail design. |
| Interface Type | Parallel (8-bit) | Parallel (8-bit) | Determines how the host communicates with the DAC; identical interface ensures firmware and pinout compatibility. |
| Package / Case | 16-SOIC | 16-SOIC | Must match for PCB footprint and assembly compatibility; identical package allows direct board replacement. |
| Mounting Type | Surface Mount | Surface Mount | Affects assembly process and board design; matching mounting type ensures physical interchangeability. |
| Packaging / Delivery Form | Tube | Tape & Reel | Affects handling and automated assembly; the reel version suits high-volume pick-and-place lines while the tube suits low-volume or prototyping. |
| Operating Temperature Range | -40 °C to +105 °C | -40 °C to +105 °C | Defines environmental limits for reliable operation; matching ranges ensure equivalent thermal performance in the application. |
| Output Type | Voltage | Voltage | Determines whether the DAC drives a voltage or current signal; matching output type ensures circuit-level compatibility. |

Frequently asked questions
What are the AD7302BRZ and AD7302BR-REEL?
Both are dual 8-bit voltage-output digital-to-analog converters (DACs) from Analog Devices. The AD7302BRZ is supplied in a 20-lead SOIC package in tube form, while the AD7302BR-REEL is the same device supplied on tape and reel for automated assembly.
Are the AD7302BRZ and AD7302BR-REEL electrically identical?
Yes. Both part numbers refer to the same AD7302 silicon in the same 20-lead SOIC (R-20) package with the same specifications. The suffix difference denotes packaging format: "Z" indicates RoHS-compliant lead-free construction, and "-REEL" indicates tape-and-reel delivery.
What is the difference between the AD7302BRZ and AD7302BR-REEL in terms of packaging?
The AD7302BRZ is delivered in tubes, while the AD7302BR-REEL is delivered on tape and reel. The tape-and-reel format is intended for high-volume pick-and-place assembly lines, whereas tubes are typically used for prototyping or lower-volume production.
What are the key specifications of the AD7302?
The AD7302 is a dual 8-bit DAC with a 2.7 V to 5.5 V supply range, a parallel interface, and a settling time of approximately 2 µs. It offers rail-to-rail output swing and is specified over the −40 °C to +105 °C temperature range. Both the AD7302BRZ and AD7302BR-REEL share these specifications.
Can the AD7302BRZ and AD7302BR-REEL be used interchangeably in a design?
Yes, from an electrical and footprint perspective they are interchangeable, since both are the same die in the same 20-lead SOIC package. The only practical difference is the delivery format, so the choice depends on the assembly process rather than circuit design.
Are both the AD7302BRZ and AD7302BR-REEL RoHS compliant?
Yes. The "Z" suffix in both part numbers denotes RoHS-compliant, lead-free construction per Analog Devices' ordering guide. Both variants meet the same environmental compliance requirements.
Which variant should be selected for high-volume production?
The AD7302BR-REEL is generally preferred for high-volume production because tape-and-reel packaging supports automated pick-and-place assembly. The AD7302BRZ in tubes is more suitable for prototyping, low-volume runs, or manual assembly.
