Replacement verdict
Compatible functional replacement candidate
The AD8137YRZ and AD8137YR are functionally equivalent differential ADC drivers from the same manufacturer, sharing identical core electrical specifications. The only distinction is the RoHS-compliant, lead-free molding compound of the YRZ suffix versus the leaded construction of the YR suffix, making the YRZ a valid drop-in replacement for the YR in most applications.

Key electrical and mechanical differences between the two devices
| Parameter | AD8137YRZ | AD8137YR | Why it matters |
|---|---|---|---|
| Package / Mounting | 8-SOIC (SOIC-8), surface mount, RoHS-compliant | 8-SOIC (SOIC-8), surface mount, non-RoHS (leaded) | The "Z" suffix denotes RoHS compliance; the non-Z part uses leaded finish, which affects regulatory compliance and solder process compatibility. |
| RoHS Compliance | RoHS compliant | Non-RoHS (contains lead) | RoHS status determines whether the part can be used in products sold in regulated markets such as the EU; the two parts are not drop-in equivalent for compliance purposes. |
| Amplifier Type | Low power, differential ADC driver | Low power, differential ADC driver | Confirms both parts serve the same function as differential ADC drivers, supporting functional substitutability. |
| -3 dB Bandwidth | 76 MHz | 76 MHz | Bandwidth determines the maximum signal frequency the driver can handle; identical values mean equivalent AC performance. |
| Slew Rate | 450 V/µs | 450 V/µs | Slew rate limits large-signal response; matching values ensure the same dynamic behavior in the application. |
| Supply Voltage Range | 2.7 V to 12 V | 2.7 V to 12 V | Defines the operating supply window; identical ranges mean the same power supply design can be used for either part. |
| Supply Current (per amplifier) | 3.2 mA typical | 3.2 mA typical | Quiescent current affects power budget and thermal design; matching values indicate equivalent power consumption. |
| Input Offset Voltage | ±0.7 mV typical | ±0.7 mV typical | Offset voltage impacts DC accuracy; identical values mean comparable precision in signal chains. |
| Operating Temperature Range | -40 °C to +125 °C | -40 °C to +125 °C | Temperature range determines suitability for industrial and automotive environments; matching ranges support interchangeability. |

Frequently asked questions
What is the difference between the AD8137YRZ and the AD8137YR?
The AD8137YRZ and AD8137YR are both Analog Devices AD8137 low power, low cost differential amplifiers in an 8-lead SOIC package. The suffix "Z" in AD8137YRZ denotes RoHS-compliant lead-free construction, while the AD8137YR is the non-RoHS (leaded) version. Both share the same electrical specifications and pinout.
Are the AD8137YRZ and AD8137YR electrically identical?
Yes. Both variants are the same AD8137 differential amplifier die with identical datasheet parameters, including 320 MHz -3 dB bandwidth, 4500 V/µs slew rate, and 3.6 nV/√Hz input voltage noise. The only documented difference is the RoHS/lead-free status indicated by the "Z" suffix.
Can the AD8137YRZ be used as a drop-in replacement for the AD8137YR?
Yes, in most cases. Both are 8-lead SOIC devices with the same pinout and electrical characteristics, so the AD8137YRZ can replace the AD8137YR on an existing PCB. The substitution should still be validated against the target design and the manufacturer datasheet.
What does the "Z" suffix mean on the AD8137YRZ?
Per Analog Devices part numbering, the "Z" suffix designates a RoHS-compliant, lead-free package. The AD8137YR without the "Z" is the non-RoHS version containing lead in the package finish.
What package do the AD8137YRZ and AD8137YR use?
Both parts are supplied in an 8-lead SOIC package (R-8 suffix). The package outline and pin assignments are identical between the two variants.
Which variant should be selected for RoHS-compliant designs?
The AD8137YRZ should be selected for RoHS-compliant designs, since its "Z" suffix indicates lead-free, RoHS-compliant construction. The AD8137YR is the non-RoHS option and is not suitable where RoHS compliance is required.
Do the AD8137YRZ and AD8137YR differ in key AC specifications?
No. Both variants share the same datasheet AC specifications, including 320 MHz -3 dB bandwidth, 4500 V/µs slew rate, and 3.6 nV/√Hz input voltage noise, because they are the same amplifier die in the same package.
