Replacement verdict
Compatible functional replacement candidate
The ADG411BRZ and ADG411BR are functionally equivalent CMOS quad SPST analog switches sharing identical on-resistance, leakage, switching speed, and supply specifications; the BRZ suffix denotes RoHS-compliant lead-free packaging versus the standard BR version, making the BRZ a direct drop-in replacement candidate where lead-free compliance is required.

Frequently asked questions
What is the difference between ADG411BRZ and ADG411BR?
The ADG411BRZ is the RoHS-compliant, lead-free (Pb-free) version of the ADG411BR, supplied in a 16-lead SOIC package. The ADG411BR is the older non-RoHS variant of the same quad SPST analog switch. Functionally and electrically they are the same device; the suffix "Z" denotes the RoHS-compliant packaging option per Analog Devices part numbering conventions.
Are ADG411BRZ and ADG411BR electrically and functionally identical?
Yes. Both are quad single-pole single-throw (SPST) analog switches from the ADG411 family, featuring low on-resistance, low leakage, and TTL/CMOS-compatible logic inputs. The "Z" suffix indicates RoHS compliance and does not change the electrical specifications or pinout.
Can ADG411BRZ be used as a direct drop-in replacement for ADG411BR?
Yes, in most cases. Both parts share the same 16-lead SOIC footprint and identical pin configuration, so the ADG411BRZ can directly replace the ADG411BR on an existing PCB. The primary difference is RoHS compliance, which matters for regulatory and environmental requirements rather than electrical performance.
What package do ADG411BRZ and ADG411BR use?
Both devices are offered in a 16-lead SOIC (Small Outline Integrated Circuit) package, designated "R" in the part number. The package outline and pin assignments are identical between the two variants.
Is ADG411BRZ RoHS compliant while ADG411BR is not?
Yes. The "Z" suffix in ADG411BRZ designates the RoHS-compliant, lead-free version per Analog Devices' part numbering. The ADG411BR is the legacy non-RoHS version. Designs requiring RoHS compliance should specify the ADG411BRZ.
What are the key specifications of the ADG411 family?
The ADG411 is a quad SPST analog switch with low on-resistance (typically around 35 Ω), low leakage current, fast switching times, and TTL/CMOS-compatible control inputs. It operates from dual supplies (e.g., ±15 V) or a single supply and is suited for signal routing, sample-and-hold, and data acquisition applications. Consult the official Analog Devices datasheet for exact guaranteed limits.
Which part should be selected for a new RoHS-compliant design?
The ADG411BRZ should be selected for new designs requiring RoHS compliance. The ADG411BR is the legacy non-RoHS variant and is generally not recommended for new designs where environmental compliance is required.
