Key electrical and mechanical differences between the two devices
| Parameter | ADG333ABRSZ | ADG333ABRS | Why it matters |
|---|---|---|---|
| Switch Configuration | 4 x SPDT (Quad SPDT) | 4 x SPDT (Quad SPDT) | Defines the number and type of switch channels; must match for functional substitutability. |
| On-Resistance (RDS(on)) | 45 Ohm (typ) | 45 Ohm (typ) | Determines signal attenuation and voltage drop through the switch; identical values ensure equivalent signal integrity. |
| Supply Voltage Range | Dual ±3 V to ±20 V, or Single 3 V to 40 V | Dual ±3 V to ±20 V, or Single 3 V to 40 V | Defines the operating power rails; matching ranges confirm the parts can be used in the same circuit supply conditions. |
| Number of Pins | 20 | 20 | Pin count must match for physical footprint and PCB layout compatibility. |
| Package / Case | 20-SSOP (Shrink Small Outline Package) | 20-SSOP (Shrink Small Outline Package) | Package type determines board footprint and assembly compatibility; identical packages allow drop-in replacement. |
| Mounting Type | Surface Mount | Surface Mount | Mounting style must match the assembly process and PCB design. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Ensures the device operates reliably across the intended environmental conditions. |
| RoHS / Lead-Free Status | RoHS Compliant, Lead-Free | Non-RoHS, Contains Lead | Affects regulatory compliance and solder process compatibility; the "Z" suffix denotes the RoHS-compliant variant. |
| Part Number Suffix / Variant | Z suffix (RoHS-compliant version) | Base version (non-RoHS) | The suffix distinguishes compliance and packaging variants; functionally equivalent but differs in environmental compliance. |

Frequently asked questions
What is the difference between the ADG333ABRSZ and the ADG333ABRS?
The ADG333ABRSZ is the RoHS-compliant, lead-free (Pb-free) version of the ADG333ABRS. Both are quad SPDT switches in a 20-lead SSOP (RS-20) package from Analog Devices. The "Z" suffix denotes the RoHS-compliant molding compound and lead finish, while the non-Z ADG333ABRS contains lead and is not RoHS compliant. Electrical and functional performance is otherwise equivalent per the manufacturer datasheet.
Are the ADG333ABRSZ and ADG333ABRS electrically and functionally interchangeable?
Yes. Both devices are the same quad SPDT analog switch with identical on-resistance, leakage, switching times, and supply requirements as specified in the Analog Devices ADG333A datasheet. The only documented difference is the RoHS/lead-free status indicated by the "Z" suffix. They are functionally interchangeable in the same circuit, provided the assembly process supports the respective lead finish.
What package do the ADG333ABRSZ and ADG333ABRS use, and are their pinouts identical?
Both parts are supplied in the 20-lead SSOP (RS-20) package. The pinout is identical between the two versions, as they share the same ADG333A silicon and package outline. PCB land patterns and pin assignments are therefore the same for both orderable part numbers.
Is the ADG333ABRSZ RoHS compliant, and is the ADG333ABRS non-compliant?
Yes. The "Z" suffix on ADG333ABRSZ designates the RoHS-compliant, lead-free version per Analog Devices ordering guide. The ADG333ABRS is the legacy non-RoHS version containing lead in its lead finish/molding. Designers requiring RoHS compliance for export or regulated markets should specify the ADG333ABRSZ.
What are the key specifications of the ADG333A quad SPDT switch?
Per the Analog Devices ADG333A datasheet, the device is a quad single-pole double-throw (SPDT) analog switch with low on-resistance (typically around 45 Ω), low leakage current, and fast switching times. It operates from dual supplies (e.g., ±15 V) or single supplies and features break-before-make switching. It is fabricated on an enhanced LC²MOS process. Designers should confirm exact limits against the current datasheet revision.
Can the ADG333ABRS be replaced by the ADG333ABRSZ in an existing design?
Yes, in most cases. Because the two parts share the same die, package, and pinout, the ADG333ABRSZ can directly replace the ADG333ABRS on an existing PCB. The substitution is appropriate when transitioning to RoHS-compliant assembly; verify that the soldering process and any regulatory documentation reflect the lead-free part number.
Which part number should be used for new RoHS-compliant designs?
New designs requiring RoHS compliance should specify the ADG333ABRSZ. The non-Z ADG333ABRS is the legacy leaded version and is generally not recommended for new designs subject to RoHS or lead-free requirements. Confirm current availability and lifecycle status with Analog Devices or an authorized distributor such as DigiKey or Mouser before finalizing the BOM.
