Replacement verdict
Compatible functional replacement candidate
The ADG406BPZ and ADG406BP are functionally equivalent CMOS analog multiplexers sharing the same 16-channel single-ended configuration, on-resistance profile, and PDIP-28 package. The ADG406BPZ represents the current RoHS-compliant revision of the same device family, making it a suitable functional replacement for the ADG406BP in existing and new designs, subject to confirmation of lead-finish and compliance requirements.

Key electrical and mechanical differences between the two devices
| Parameter | ADG406BPZ | ADG406BP | Why it matters |
|---|---|---|---|
| Number of Channels | 8 | 8 | Defines how many independent signal paths the multiplexer can switch; must match for functional substitutability. |
| Switch Configuration | 8:1 Multiplexer | 8:1 Multiplexer | Determines the switching topology (multiplexer vs. demultiplexer); identical configuration ensures the same signal routing behavior. |
| On-Resistance (Typical) | 50 Ohm | 50 Ohm | Affects signal attenuation and insertion loss; matching on-resistance preserves circuit performance. |
| Supply Voltage Range | ±15 V (dual) or +12 V (single) | ±15 V (dual) or +12 V (single) | Must be compatible with the system power rails; identical ranges allow drop-in replacement. |
| Package / Mounting | 28-Pin PDIP (Through-Hole) | 28-Pin PDIP (Through-Hole) | Physical footprint and mounting style must match for board-level interchangeability. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +85°C | Ensures the device operates reliably within the target application's environmental conditions. |
| Channel-to-Channel Matching | 5 Ohm (typ) | 5 Ohm (typ) | Low matching error maintains signal integrity across channels; identical values preserve accuracy. |
| Switching Time (tON/tOFF) | 250 ns / 200 ns (typ) | 250 ns / 200 ns (typ) | Determines maximum switching frequency and timing behavior; matching values ensure identical dynamic response. |
| Leakage Current (Off) | 0.5 nA (typ) | 0.5 nA (typ) | Low leakage preserves signal accuracy in high-impedance circuits; identical leakage ensures equivalent performance. |

Frequently asked questions
What is the difference between the ADG406BPZ and the ADG406BP?
The ADG406BPZ and ADG406BP are both 16-channel analog multiplexers from Analog Devices. The primary difference is the package and lead finish: the ADG406BPZ is supplied in a 28-lead PDIP with a lead-free, RoHS-compliant finish, while the ADG406BP is the older non-RoHS version of the same device in the same 28-lead PDIP package. Functionally and electrically they are the same multiplexer.
Are the ADG406BPZ and ADG406BP electrically identical?
Yes. Both parts share the same datasheet specifications for the ADG406 family: 16-channel single-ended multiplexing, on-resistance of approximately 50 ohms typical, low charge injection, and TTL/CMOS-compatible logic inputs. The electrical performance is the same; the difference is the package finish and RoHS status.
Can the ADG406BPZ be used as a drop-in replacement for the ADG406BP?
Yes, in most cases. Both are 28-lead PDIP devices with identical pinouts and the same functional specifications, so the ADG406BPZ can replace the ADG406BP in existing designs. The ADG406BPZ is the RoHS-compliant version, so it is the preferred choice for new designs and for compliance with lead-free manufacturing requirements.
Is the ADG406BPZ RoHS compliant?
Yes. The "Z" suffix in the ADG406BPZ part number indicates a lead-free, RoHS-compliant package finish, per Analog Devices' part numbering convention. The ADG406BP does not carry this suffix and is the non-RoHS version.
What are the key specifications of the ADG406 multiplexer?
The ADG406 is a 16-channel single-ended analog multiplexer with on-resistance of about 50 ohms typical, low charge injection, and TTL/CMOS-compatible digital inputs. It operates from dual supplies (typically ±15 V) or a single supply, and is available in 28-lead PDIP and other package options. Designers should confirm exact limits against the current Analog Devices datasheet.
Which part should be selected for a new design, ADG406BPZ or ADG406BP?
For new designs, the ADG406BPZ is the appropriate choice because it is the RoHS-compliant, lead-free version and is the currently supported ordering option. The ADG406BP is the legacy non-RoHS variant and should only be used where existing inventory or specific legacy requirements demand it.
Do the ADG406BPZ and ADG406BP have the same pinout and package?
Yes. Both devices are offered in the 28-lead PDIP package with the same pin configuration, so PCB land patterns and socketing are identical. The only distinction is the lead finish and RoHS compliance indicated by the "Z" suffix.
