ADF4350BCPZ Alternatives and Equivalents
ADF4350 wideband PLL/VCO synthesizer · Analog Devices · verified against manufacturer datasheet parameters
ADF4350BCPZ — a ADF4350 wideband PLL/VCO synthesizer part from Analog Devices — is one of the most-searched part numbers in its category. This page compares its verified pin-compatible variants and closest family alternates, using manufacturer datasheet parameters, and shows what is actually available from stock.
The table below distinguishes true drop-in replacements (same package and pinout) from family alternates that need design review. Specs marked "—" vary by suffix or were not published in the source data — confirm on the datasheet before committing.

Is the ADF4350BCPZ discontinued?
ADF4350BCPZ is part of Analog Devices' ADF4350 wideband synthesizer family (integrated PLL + VCO, 137.5 MHz–4.4 GHz class). Active production; A/B die revisions and package/packing suffixes circulate in parallel on the market.
Pin-to-pin compatible alternatives
"Drop-in" means same package and pinout; other rows are family alternates that need design review.
| Part Number | Compatibility | Package |
|---|---|---|
| ADF4350BCPZ (target) | — | LFCSP |
| ADF4350ABCPZ | Drop-in (same package & pinout) | LFCSP |
| ADF4350BCPZ-RL | Family alternate — review design | LFCSP |
ADF4350BCPZ vs ADF4350ABCPZ: what actually differs
Within the compared parameter set these codes match on the published specs; the differences live in suffix details — packing, temperature grade or flash/density options. Send both codes if you want us to confirm the delta on your specific requirement.
Migration checklist: re-validate before you swap
- A/B revisions (ADF4350A vs ADF4350B) are register-compatible but check the phase-noise and spur specs that matter to you
- RL/RL7 suffixes = reel packing variants — electrically identical
- The external loop filter design carries across revisions unchanged
- Verify reference input and charge-pump settings in software after any revision change
- Package (LFCSP) is shared — footprint-compatible across revisions
Where to source ADF4350BCPZ and its alternates
We stock ADF4350BCPZ and its family variants in Hong Kong with date codes stated on every quote. Each lot passes marking verification; X-ray and electrical testing through accredited partner labs are available on request, with the report delivered before final payment.
Pricing follows the live spot market, so quotes carry a stated validity window — typically 24 to 48 hours on volatile lines. Send your quantity and required date code and the desk replies within 2 working hours.
ADF4350BCPZ can also ship consolidated with the rest of your BOM — one shipment, one invoice, one inspection standard. For recurring demand we reserve stock and schedule multi-lot releases, which smooths both price exposure and availability risk across your build calendar.

FAQ
ADF4350A vs ADF4350B — what changed?
Die revision. Register-compatible; some RF performance parameters differ. For most designs they are drop-in alternates.
Is ADF4350BCPZ discontinued?
No — the ADF4350 family is active.
Are RL/RL7 suffixes different parts?
No — tape-and-reel packing variants of the same device.
Do I need to change my loop filter?
No — revisions share the same external loop filter design.
How are RF parts packed for shipment?
ESD-safe, moisture-barrier packing with full labels.
Can you source the evaluation board?
Yes — send the part number and we quote it.
Can I see photos or test reports before ordering?
Yes — label and top-marking photos of the actual lot are standard, and X-ray or lab reports can be arranged before payment on first orders. Tell the desk what your incoming inspection requires.
Do you support scheduled production deliveries?
Yes. For recurring demand we reserve stock of ADF4350BCPZ or its alternates and release shipments against your build schedule — one agreement instead of repeated spot buys.
