Replacement verdict
Compatible functional replacement candidate
The ADG408BR and ADG408BR-REEL are functionally identical CMOS analog multiplexers; the only distinction is packaging format, with the -REEL variant supplied on tape and reel for automated assembly. Both share the same 8-channel differential configuration, on-resistance, supply range, and 16-lead SOIC footprint, making them interchangeable in design. The -REEL suffix affects only the shipping medium, not device performance or pinout.

Key electrical and mechanical differences between the two devices
| Parameter | ADG408BR | ADG408BR-REEL | 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 routing topology (multiplexer vs. demultiplexer); identical configuration ensures drop-in compatibility. |
| On-State Resistance (RON) | 100 Ω (typ) | 100 Ω (typ) | Affects signal attenuation and voltage drop across the switch; matching RON preserves signal integrity in the target circuit. |
| Supply Voltage Range | ±15 V dual / 12 V single | ±15 V dual / 12 V single | Must match the system power rails; identical ranges allow the part to operate in the same supply environment. |
| Package / Mounting | 16-SOIC (Surface Mount) | 16-SOIC (Surface Mount) | Footprint and mounting style must match for PCB compatibility; both use the same 16-SOIC package. |
| Channel-to-Channel Matching | 5 Ω (typ) | 5 Ω (typ) | Low matching error ensures consistent gain across channels; identical values preserve channel-to-channel accuracy. |
| Switching Time (tON/tOFF) | ~250 ns / ~150 ns | ~250 ns / ~150 ns | Determines maximum switching frequency and settling behavior; matching timing keeps dynamic performance unchanged. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Ensures the device meets environmental requirements of the application; identical ratings allow use in the same thermal conditions. |
| Packaging / Delivery Form | Tube / individual | Tape & Reel | Affects manufacturing handling and pick-and-place assembly; the reel version suits automated high-volume production while the tube version suits prototyping or low-volume builds. |

Frequently asked questions
What is the difference between ADG408BR and ADG408BR-REEL?
The ADG408BR and ADG408BR-REEL are the same device: an 8-channel analog multiplexer in a 16-lead SOIC package. The "-REEL" suffix denotes tape-and-reel packaging for automated assembly, while ADG408BR is typically supplied in tube or tray packaging. Electrical and functional specifications are identical.
Are the ADG408BR and ADG408BR-REEL electrically and functionally identical?
Yes. Both parts share the same die and datasheet specifications, including on-resistance, channel-to-channel matching, leakage current, and switching times. The only documented difference is the packaging format (reel versus tube/tray).
Can ADG408BR-REEL be used as a drop-in replacement for ADG408BR?
Yes, provided the assembly process supports tape-and-reel feeding. The device, pinout, and 16-lead SOIC footprint are the same, so no PCB layout change is required.
What package does the ADG408BR use?
The ADG408BR is supplied in a 16-lead SOIC (Small Outline Integrated Circuit) package, designated by the "R" suffix in the part number. The ADG408BR-REEL uses the same 16-lead SOIC package.
Why would a designer choose the -REEL version over the tube version?
The -REEL version is intended for high-volume automated pick-and-place assembly lines, where tape-and-reel packaging improves throughput and reduces handling. Tube packaging is typically used for prototyping or low-volume runs.
Do ADG408BR and ADG408BR-REEL have the same operating temperature range?
Yes. Both are specified over the same industrial temperature range as documented in the Analog Devices ADG408 datasheet. The packaging format does not affect the temperature specification.
Are ADG408BR and ADG408BR-REEL RoHS compliant?
RoHS compliance depends on the specific ordering code and manufacturer documentation. Designers should verify the compliance status of the exact ordering code against the Analog Devices product page or datasheet before finalizing a design.
