Replacement verdict
Compatible functional replacement candidate
The ADG712BRUZ and ADG712BRU are functionally equivalent CMOS analog switches sharing identical switch architecture, on-resistance, channel count, and TSSOP-16 footprint; the only distinction is the RoHS-compliant Z suffix on the ADG712BRUZ, making it a direct drop-in replacement for the non-Z variant in both new and existing designs.

Key electrical and mechanical differences between the two devices
| Parameter | ADG712BRUZ | ADG712BRU | Why it matters |
|---|---|---|---|
| Switch Configuration | SPST (2x Normally Open) | SPST (2x Normally Open) | Defines the switching topology; both parts must match for the circuit to function identically. |
| Number of Channels | 2 | 2 | Channel count determines how many independent signals can be routed; must match for drop-in substitution. |
| On-Resistance (Typical) | 2.5 Ω | 2.5 Ω | Low on-resistance minimizes signal attenuation and voltage drop; identical values ensure equivalent signal integrity. |
| Supply Voltage Range | 1.8 V to 5.5 V | 1.8 V to 5.5 V | Determines compatibility with the system power rail; matching ranges confirm the parts are interchangeable. |
| Package / Mounting | 16-TSSOP (Surface Mount) | 16-TSSOP (Surface Mount) | Package and footprint must match for physical board compatibility and reflow assembly. |
| RoHS Compliance | RoHS Compliant (Pb-Free) | Non-RoHS (Contains Lead) | RoHS status affects regulatory compliance and solder process; the "Z" suffix denotes the lead-free variant. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Confirms the part operates across the same environmental conditions in the target application. |
| Switching Time (tON/tOFF) | ~14 ns / ~6 ns | ~14 ns / ~6 ns | Fast switching times are critical for signal routing timing; identical values preserve dynamic performance. |

Frequently asked questions
What is the difference between ADG712BRUZ and ADG712BRU?
The ADG712BRUZ is the RoHS-compliant, lead-free (Pb-free) version of the ADG712BRU. Both are quad SPST CMOS analog switches in a 16-lead TSSOP package with identical electrical specifications; the "Z" suffix denotes the RoHS-compliant packaging option per Analog Devices part numbering.
Are ADG712BRUZ and ADG712BRU electrically and functionally identical?
Yes. Both parts share the same datasheet specifications: quad SPST switches, on-resistance of approximately 4 Ω typical at ±5 V dual supply, low leakage, and CMOS logic compatibility. The only documented difference is the RoHS/lead-free compliance designation indicated by the "Z" suffix.
Can ADG712BRUZ be used as a direct replacement for ADG712BRU?
Yes, in most designs the ADG712BRUZ is a drop-in replacement for the ADG712BRU because the package, pinout, and electrical parameters are the same. The substitution should still be validated against the manufacturer datasheet and the target design's compliance requirements.
What package do ADG712BRUZ and ADG712BRU use?
Both devices are supplied in a 16-lead TSSOP (Thin Shrink Small Outline Package), designated "RU" in the Analog Devices part number. The package footprint and pin assignments are identical between the two variants.
Does the "Z" suffix affect the electrical performance of ADG712BRUZ?
No. The "Z" suffix in Analog Devices nomenclature indicates RoHS compliance and lead-free construction; it does not change the device's electrical specifications. On-resistance, switching times, leakage, and supply range remain as specified in the ADG712 datasheet.
Which variant should be selected for RoHS-compliant designs?
ADG712BRUZ should be selected for RoHS-compliant and lead-free assembly requirements, since the "Z" suffix denotes RoHS compliance. ADG712BRU is the non-RoHS legacy ordering option and should be avoided in new lead-free designs.
What are the key specifications common to both ADG712BRUZ and ADG712BRU?
Both are quad SPST CMOS analog switches with low on-resistance (approximately 4 Ω typical), dual-supply operation (typically ±5 V) or single-supply operation, low power consumption, and TTL/CMOS-compatible logic inputs, as documented in the Analog Devices ADG712 datasheet.
