Key electrical and mechanical differences between the two devices
| Parameter | ADR425BRZ | ADR425BR-REEL7 | Why it matters |
|---|---|---|---|
| Initial Accuracy | ±0.04% (max) | ±0.04% (max) | Determines the output voltage tolerance at 25°C; identical grade ensures the same initial precision. |
| Output Voltage | 5.000 V | 5.000 V | The nominal reference voltage must match for the parts to be functionally interchangeable in a circuit. |
| Temperature Coefficient | 3 ppm/°C (max) | 3 ppm/°C (max) | Governs voltage drift over temperature; matching tempco ensures equivalent stability across the operating range. |
| Initial Accuracy Grade | B Grade | B Grade | The grade suffix defines the guaranteed accuracy and tempco bin; both being B grade confirms equivalent performance class. |
| Package / Mounting | 8-SOIC (surface mount) | 8-SOIC (surface mount) | Same package and footprint allows drop-in replacement on an existing PCB layout. |
| Supply Voltage Range | 7 V to 18 V | 7 V to 18 V | Defines the allowable input supply; identical range means the same power rail can drive either part. |
| Operating Temperature Range | -40°C to +125°C | -40°C to +125°C | Confirms both parts are rated for the same environmental conditions and applications. |
| Packaging / Delivery Form | Tube | Tape & Reel (7-inch) | Delivery format affects assembly line handling; reel packaging suits automated pick-and-place while tube suits manual or low-volume use. |
| Ordering Part Number Suffix | Z (RoHS-compliant tube) | REEL7 (reel packaging) | The suffix encodes packaging and compliance; different suffixes mean different logistics but the same silicon die. |

Frequently asked questions
What is the difference between ADR425BRZ and ADR425BR-REEL7?
Both parts are the same ADR425 voltage reference die in an 8-lead SOIC package with a B-grade tolerance of ±0.04% initial accuracy and 3 ppm/°C temperature coefficient. The difference is packaging format: ADR425BRZ is supplied in tube/tray packaging, while ADR425BR-REEL7 is supplied on a 7-inch tape-and-reel for automated assembly. Electrical specifications are identical.
Are ADR425BRZ and ADR425BR-REEL7 electrically interchangeable?
Yes. Both are the same ADR425B die in the same 8-lead SOIC (R-8) package with identical pinout, reference output of 5.000 V, initial accuracy of ±0.04%, and temperature coefficient of 3 ppm/°C. They differ only in shipping packaging, so they are electrically and functionally interchangeable.
What is the output voltage and accuracy of the ADR425BRZ?
The ADR425BRZ provides a 5.000 V output with an initial accuracy of ±0.04% (B grade) and a temperature coefficient of 3 ppm/°C maximum over the specified temperature range. These parameters are common to both the ADR425BRZ and ADR425BR-REEL7.
What package do ADR425BRZ and ADR425BR-REEL7 use?
Both parts are offered in an 8-lead SOIC package (Analog Devices R-8 suffix). The package, pinout, and land pattern are identical, so PCB footprint compatibility is the same for both ordering codes.
Why would a designer choose ADR425BR-REEL7 over ADR425BRZ?
ADR425BR-REEL7 is supplied on a 7-inch tape-and-reel, which is suited to automated pick-and-place production lines and high-volume assembly. ADR425BRZ in tube/tray packaging is typically used for prototyping, low-volume runs, or manual assembly. The choice is purely a manufacturing/packaging decision, not an electrical one.
Do ADR425BRZ and ADR425BR-REEL7 share the same operating temperature range and supply requirements?
Yes. Both ordering codes refer to the same ADR425B device, so they share the same specified operating temperature range and supply voltage requirements as documented in the Analog Devices ADR425 datasheet. Packaging format does not affect these ratings.
Can ADR425BRZ and ADR425BR-REEL7 be used interchangeably in an existing design?
Yes, from an electrical and footprint standpoint they are the same device in the same 8-lead SOIC package. The only practical consideration is the assembly process: ADR425BR-REEL7 requires tape-and-reel handling equipment, while ADR425BRZ is handled from tubes/trays. Verify current availability and lifecycle status with the distributor before switching ordering codes.
