Replacement verdict
Compatible functional replacement candidate
The ADF4371BCCZ and ADF4371BCCZ-RL7 are the same silicon device offered under different ordering formats, so they are functionally interchangeable. The only meaningful distinction is packaging and delivery format, which affects procurement and inventory handling rather than electrical performance or board-level behavior.

Key electrical and mechanical differences between the two devices
| Parameter | ADF4371BCCZ | ADF4371BCCZ-RL7 | Why it matters |
|---|---|---|---|
| Manufacturer | Analog Devices Inc. | Analog Devices Inc. | Same manufacturer ensures identical silicon design and process, critical for functional substitutability. |
| Function / Type | Microwave Wideband Synthesizer with Integrated VCO | Microwave Wideband Synthesizer with Integrated VCO | Identical device function confirms the parts are the same IC and directly interchangeable in a design. |
| Frequency Range | 62.5 MHz to 32 GHz | 62.5 MHz to 32 GHz | Output frequency range must match to ensure the part covers the target application band. |
| Package / Case | 48-VFQFN Exposed Pad (LFCSP) | 48-VFQFN Exposed Pad (LFCSP) | Package footprint and pinout must match for drop-in PCB compatibility. |
| Supply Voltage | 3.0 V to 3.6 V (3.3 V nominal) | 3.0 V to 3.6 V (3.3 V nominal) | Operating supply range must be compatible with the board's power rail design. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +85°C | Temperature rating must satisfy the application's environmental requirements. |
| Packaging / Ordering Format | Tray / Cut Tape (single-unit or tray quantities) | Tape & Reel (7-inch reel, 750 units) | Packaging differs for automated assembly vs. prototyping; the -RL7 suffix denotes reel packaging for high-volume pick-and-place lines. |
| Moisture Sensitivity Level (MSL) | MSL 3 | MSL 3 | MSL governs handling and bake-out requirements; identical MSL means the same floor-life and storage procedures apply. |
| RoHS Compliance | RoHS Compliant | RoHS Compliant | Both meet RoHS, ensuring regulatory compliance for commercial and consumer markets. |

Frequently asked questions
What is the difference between ADF4371BCCZ and ADF4371BCCZ-RL7?
The ADF4371BCCZ and ADF4371BCCZ-RL7 are the same ADF4371 microwave wideband synthesizer with integrated VCO. The suffix difference refers to packaging format: ADF4371BCCZ is the standard tray packaging, while ADF4371BCCZ-RL7 is the tape-and-reel packaging option. Both share identical electrical specifications and the same 48-lead LFCSP package.
Are the ADF4371BCCZ and ADF4371BCCZ-RL7 electrically and functionally identical?
Yes. Both part numbers refer to the same silicon device, the ADF4371 microwave wideband synthesizer with integrated VCO. The -RL7 suffix only denotes tape-and-reel delivery format, so electrical performance, frequency range, and functional behavior are identical between the two order codes.
What is the output frequency range of the ADF4371?
The ADF4371 provides a fundamental output frequency range of 62.5 MHz to 32 GHz, with extended operation possible when using the integrated VCO doubler and divider paths. The device integrates a VCO covering the microwave bands and supports fractional-N synthesis for fine frequency resolution.
What package and pin count do the ADF4371BCCZ and ADF4371BCCZ-RL7 use?
Both variants are supplied in a 48-lead LFCSP (lead frame chip scale package). The package and pinout are identical between the tray and tape-and-reel versions, so PCB footprint and layout requirements are the same for both order codes.
Which packaging option should be selected for high-volume automated assembly?
For high-volume automated pick-and-place assembly, ADF4371BCCZ-RL7 (tape-and-reel) is typically preferred because it is compatible with automated reel-fed placement equipment. ADF4371BCCZ (tray) is generally used for prototyping, low-volume runs, or manual handling.
Do the ADF4371BCCZ and ADF4371BCCZ-RL7 differ in moisture sensitivity level or handling requirements?
No. Because both order codes contain the same device in the same 48-lead LFCSP package, moisture sensitivity level and handling requirements are determined by the package and are the same for both variants. Users should still follow the manufacturer's datasheet and packaging labels for bake and storage instructions.
Can ADF4371BCCZ and ADF4371BCCZ-RL7 be used interchangeably in a design?
Yes, from an electrical and mechanical standpoint the two order codes are interchangeable because they represent the same device in the same package. The only practical difference is the delivery format (tray versus tape-and-reel), which affects manufacturing handling rather than circuit design.
