Replacement verdict
Compatible functional replacement candidate
The AD7175-2BRUZ-RL7 and AD7175-2BRUZ are functionally identical 24-bit sigma-delta ADCs from Analog Devices, differing only in packaging format (tape-and-reel versus tube). Both share the same die, pinout, TSSOP-24 package, and full electrical specifications, making them interchangeable for design and production purposes. The RL7 suffix denotes reel packaging suited to automated SMT assembly, while the base part is supplied in tubes. Selection should be driven by manufacturing handling requirements rather than electrical or functional differences.

Key electrical and mechanical differences between the two devices
| Parameter | AD7175-2BRUZ-RL7 | AD7175-2BRUZ | Why it matters |
|---|---|---|---|
| Resolution (bits) | 24 | 24 | Both parts provide 24-bit resolution, so measurement precision is identical and they are functionally interchangeable in this respect. |
| Number of ADC channels | 2 (differential) | 2 (differential) | Channel count determines how many signal inputs can be measured; identical channel configuration means the same sensor front-end can be reused. |
| Sampling rate (max) | 250 kSPS | 250 kSPS | Maximum output data rate affects achievable bandwidth and settling; matching rates ensure equivalent dynamic performance in the application. |
| Supply voltage (analog) | 4.5 V to 5.5 V | 4.5 V to 5.5 V | Analog supply range must match the system rail; identical ranges allow the same power design and decoupling to be used. |
| Interface type | SPI (serial) | SPI (serial) | The digital interface must be compatible with the host controller; both use SPI, so firmware and bus wiring remain unchanged. |
| Package / mounting | 24-lead TSSOP (surface mount) | 24-lead TSSOP (surface mount) | Package and footprint must match for PCB drop-in replacement; identical TSSOP packages allow the same land pattern. |
| Packaging / order quantity | Tape and reel (RL7, 7-inch reel) | Tube / tray (standard bulk) | Delivery format affects automated assembly and inventory handling; the reel version suits high-volume pick-and-place lines while the bulk version suits prototyping or low-volume builds. |
| Operating temperature range | -40 °C to +105 °C | -40 °C to +105 °C | Temperature range determines suitability for industrial environments; identical ratings mean the same thermal margin applies. |

Frequently asked questions
What is the difference between AD7175-2BRUZ-RL7 and AD7175-2BRUZ?
Both are the same AD7175-2 device in a 24-lead TSSOP package. The suffix difference is packaging: AD7175-2BRUZ is the standard tube/tray ordering option, while AD7175-2BRUZ-RL7 denotes tape-and-reel packaging (7-inch reel) for automated assembly. Electrical and functional specifications are identical.
Are AD7175-2BRUZ-RL7 and AD7175-2BRUZ electrically and functionally interchangeable?
Yes. Both order codes refer to the same silicon die and package (24-lead TSSOP), so resolution, channel count, interface, and performance specifications are the same. The only difference is the shipping form (reel versus tube/tray), which does not affect device operation.
What are the key specifications of the AD7175-2?
The AD7175-2 is a 24-bit, 2-channel (multiplexed) sigma-delta ADC with an integrated analog front end. It supports output data rates up to 250 kSPS and offers selectable gain and multiple filter options. It communicates via an SPI-compatible serial interface and operates from a single supply with a separate digital I/O supply. Refer to the official datasheet for full verified limits.
Which package do both order codes use, and is it RoHS compliant?
Both AD7175-2BRUZ-RL7 and AD7175-2BRUZ use the 24-lead TSSOP package. The "Z" in the part number indicates RoHS-compliant, lead-free construction per Analog Devices ordering conventions.
Can I substitute AD7175-2BRUZ-RL7 for AD7175-2BRUZ in production?
Yes, from an electrical standpoint they are the same device. The choice depends on your assembly process: -RL7 is supplied on tape-and-reel for automated pick-and-place, while the non-reel version is supplied in tubes/trays. Verify reel quantity and handling requirements against your manufacturing needs.
What is the difference in moisture sensitivity level (MSL) between the two order codes?
MSL is determined by the package and is the same for both order codes since both use the identical 24-lead TSSOP body. Confirm the specific MSL rating from the Analog Devices datasheet or product page before setting bake/reflow profiles.
Do both parts share the same SPI interface and pinout?
Yes. Because both order codes are the same AD7175-2 in the same 24-lead TSSOP package, the pinout and SPI-compatible serial interface are identical. PCB land patterns and firmware drivers apply equally to both.
Which order code should I choose for high-volume automated assembly?
AD7175-2BRUZ-RL7 is the tape-and-reel option intended for automated pick-and-place assembly lines. AD7175-2BRUZ (tube/tray) is typically used for prototyping, low-volume, or manual assembly. Select based on your SMT line requirements and reel quantity needs.
