Replacement verdict
Compatible functional replacement candidate
The ADG609BRZ is a functionally compatible replacement candidate for the ADG609BR, sharing the same dual 4-channel CMOS analog multiplexer architecture, 44 V supply range, and 16-lead SOIC footprint. The primary distinction is the RoHS-compliant Z-grade package designation, which requires validation against the original board's assembly and compliance requirements before substitution.

Key electrical and mechanical differences between the two devices
| Parameter | ADG609BRZ | ADG609BR | Why it matters |
|---|---|---|---|
| Number of Channels | 2 | 2 | Determines how many independent signal paths the switch can route; must match for functional substitutability. |
| Switch Configuration | 4:1 Multiplexer | 4:1 Multiplexer | Defines the switching topology (mux/demux arrangement); identical configuration is required for drop-in replacement. |
| On-Resistance (Typical) | 30 Ohm | 30 Ohm | Affects signal attenuation and insertion loss; matching on-resistance preserves circuit performance. |
| Supply Voltage Range | +3 V to +5 V (single) / +/-5 V (dual) | +3 V to +5 V (single) / +/-5 V (dual) | Must be compatible with the system power rails for the part to operate correctly in the target design. |
| Package / Mounting | 16-Lead SOIC (Surface Mount) | 16-Lead SOIC (Surface Mount) | Footprint and mounting style must match for physical board compatibility. |
| Operating Temperature Range | -40 C to +85 C | -40 C to +85 C (industrial) | Temperature rating affects reliability and suitability across environments; differences may limit use in extreme conditions. |
| Channel-to-Channel Matching | 5 Ohm (typ) | 5 Ohm (typ) | Matching between channels impacts differential signal accuracy and crosstalk performance. |
| Switching Time (tON/tOFF) | 75 ns / 45 ns (typ) | 75 ns / 45 ns (typ) | Determines how fast the switch can transition; critical for timing-sensitive multiplexing applications. |
| Logic Control Interface | TTL/CMOS Compatible | TTL/CMOS Compatible | Ensures the control inputs interface directly with standard digital logic levels in the system. |

Frequently asked questions
What is the difference between the ADG609BRZ and the ADG609BR?
The ADG609BRZ is the RoHS-compliant, lead-free (Pb-free) version of the ADG609BR. Both are dual 4-channel analog multiplexers in a 16-lead SOIC package with identical electrical specifications; the "Z" suffix denotes the lead-free/RoHS-compliant package variant per Analog Devices part numbering.
Are the ADG609BRZ and ADG609BR electrically and functionally identical?
Yes. Both devices are dual 4:1 analog multiplexers with the same on-resistance, channel-to-channel matching, leakage, and switching characteristics as specified in the Analog Devices ADG609 datasheet. The only documented difference is the package finish (lead-free/RoHS for the BRZ versus standard for the BR).
Can the ADG609BRZ be used as a direct drop-in replacement for the ADG609BR?
Yes, in most cases. Both are supplied in the same 16-lead SOIC (R-16) package with identical pinout and function. The ADG609BRZ is the RoHS-compliant equivalent, so it can replace the ADG609BR where lead-free/RoHS compliance is required, provided the board assembly process supports the higher reflow temperature associated with Pb-free parts.
What are the key specifications of the ADG609 multiplexers?
Per the Analog Devices ADG609 datasheet, the devices are dual 4-channel (4:1) analog multiplexers featuring low on-resistance (typically around 30 Ω), low leakage currents, fast switching times, and single-supply or dual-supply operation. They are fabricated on an enhanced LC²MOS process and are specified for TTL/CMOS-compatible logic inputs.
What package do the ADG609BRZ and ADG609BR use?
Both parts are offered in a 16-lead SOIC package (Analog Devices package designation R-16). The ADG609BRZ uses the lead-free/RoHS-compliant version of this package, while the ADG609BR uses the standard (non-RoHS) finish.
Does the "Z" suffix affect the operating temperature range or electrical performance?
No. The "Z" suffix in Analog Devices nomenclature indicates RoHS compliance/lead-free construction and does not change the specified operating temperature range or electrical parameters. Both the ADG609BRZ and ADG609BR are specified over the same industrial temperature range as documented in the datasheet.
Which part should be selected for a new RoHS-compliant design?
The ADG609BRZ should be selected for new designs requiring RoHS compliance, as it is the lead-free variant. The ADG609BR is the non-RoHS version and is generally intended for legacy designs or applications where leaded finish is explicitly required.
