Replacement verdict
Compatible functional replacement candidate
The ADG452BRZ is a functionally compatible replacement candidate for the ADG452BR, as both parts share the same core analog switch architecture, channel configuration, and package footprint. The primary distinction is the BRZ suffix, which denotes RoHS-compliant lead-free construction versus the leaded construction of the BR variant, making the BRZ suitable for current environmental compliance requirements while preserving electrical interchangeability.

Key electrical and mechanical differences between the two devices
| Parameter | ADG452BRZ | ADG452BR | Why it matters |
|---|---|---|---|
| Package / Mounting | 16-Lead SOIC (surface mount) | 16-Lead SOIC (surface mount) | Both use the same SOIC-16 footprint, so board layout is interchangeable; the difference lies in the ordering suffix (Z = RoHS-compliant lead-free). |
| RoHS / Lead-Free Status | RoHS compliant, lead-free (Z suffix) | Non-RoHS, contains lead (no Z suffix) | The Z suffix denotes the lead-free/RoHS version; this affects regulatory compliance and solder process compatibility, not electrical function. |
| Switch Configuration | 4 x SPST (normally open) | 4 x SPST (normally open) | Identical switch topology ensures the same signal routing behavior in the application circuit. |
| On-Resistance (R_ON) | 5 Ω (typical) | 5 Ω (typical) | Matching on-resistance means equivalent signal attenuation and insertion loss in the signal path. |
| Supply Voltage Range | ±4.5 V to ±20 V dual, or +4.5 V to +40 V single | ±4.5 V to ±20 V dual, or +4.5 V to +40 V single | Same supply range allows direct substitution without redesigning the power rail. |
| Channel-to-Channel Matching | 0.5 Ω (typical) | 0.5 Ω (typical) | Identical matching ensures consistent gain/offset across channels in multiplexed or differential designs. |
| Switching Time (t_ON / t_OFF) | 70 ns / 60 ns (typical) | 70 ns / 60 ns (typical) | Same switching speed preserves timing behavior in sampling and signal-routing applications. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Identical temperature ratings confirm equivalent environmental robustness for the same application. |

Frequently asked questions
What is the difference between ADG452BRZ and ADG452BR?
The ADG452BRZ is the RoHS-compliant version of the ADG452BR. Both are quad SPST switches from Analog Devices in a 16-lead SOIC package, but the "Z" suffix indicates lead-free (Pb-free) construction and RoHS compliance, while the ADG452BR is the non-RoHS leaded version.
Are ADG452BRZ and ADG452BR electrically and functionally identical?
Yes. Both parts share the same datasheet specifications: quad SPST normally open switches, on-resistance of approximately 4 Ω typical, dual-supply operation of ±4.5 V to ±20 V or single-supply operation of 4.5 V to 40 V, and TTL/CMOS-compatible logic inputs. The only documented difference is the package finish (Pb-free vs. leaded).
Can ADG452BRZ be used as a drop-in replacement for ADG452BR?
Yes, in most cases. Both are offered in the same 16-lead SOIC package with identical pinout and specified electrical performance. The ADG452BRZ is the recommended replacement where RoHS compliance is required; verify solder profile compatibility with the Pb-free finish in the target assembly process.
What are the key specifications of the ADG452 family?
The ADG452 is a quad SPST normally open analog switch featuring low on-resistance (about 4 Ω typical), low leakage current, fast switching times (tON/tOFF in the tens of nanoseconds), and rail-to-rail analog signal handling. It operates from ±4.5 V to ±20 V dual supplies or 4.5 V to 40 V single supply and is controlled by TTL/CMOS-compatible logic.
Is the ADG452BR still available, or is it obsolete?
The ADG452BR (non-RoHS, leaded) has been superseded by the ADG452BRZ in Analog Devices' portfolio as the industry transitions to Pb-free, RoHS-compliant packaging. Designers should confirm current availability and lifecycle status with authorized distributors such as DigiKey or Mouser before specifying the non-Z version for new designs.
What package do ADG452BRZ and ADG452BR use?
Both devices are supplied in a 16-lead SOIC (small outline integrated circuit) package, designated by Analog Devices as the R-16 suffix. The package footprint and pin assignments are identical between the two versions, allowing the same PCB land pattern to be used.
Do ADG452BRZ and ADG452BR differ in operating temperature range?
No. Both versions are specified over the industrial temperature range of −40 °C to +85 °C, consistent with the ADG452 datasheet. The Z suffix denotes package/lead finish compliance, not a temperature grade change.
