TPS51116RGE Alternatives and Equivalents
DDR power / termination regulator · Texas Instruments · verified against manufacturer datasheet parameters
TPS51116RGE — a DDR power / termination regulator part from Texas Instruments — 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.
This cross-reference is part of our guide to obsolete electronic components — These cross-references cover discontinued, EOL and allocation-constrained parts — the full risk framework is in our pillar guide.

Is the TPS51116RGE discontinued?
TPS51116RGE is part of TI's DDR memory power family (VTT termination and VDD rails). These parts ride the DDR3/DDR4 installed base — active production, but package variants rotate through availability. RGE (VQFN) and its reel variant RGER are the same device in different packing.
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 | Number of Outputs | Operating Temperature | Package / Case |
|---|---|---|---|---|---|
| TPS51116RGE (target) | — | VQFN | 1 | -40°C ~ 85°C | 24-VFQFN Exposed Pad |
| TPS51116RGET | Drop-in (same package & pinout) | 24-VFQFN Exposed Pad | 1 | -40°C ~ 85°C | 24-VFQFN Exposed Pad |

TPS51116RGE vs TPS51116RGET: 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
- R vs no-R suffix = tape-and-reel vs tube/tray packing — electrically identical
- Verify the regulator supports your DDR generation's VTT/VDDQ requirements
- Check package thermal pad connection against your PCB land pattern
- Confirm source/sink current rating covers your memory configuration
- Re-validate power-up sequencing for the memory rail
Where to source TPS51116RGE and its alternates
We stock TPS51116RGE 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.
TPS51116RGE 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
RGE vs RGER — what is the difference?
Packing only: RGER is tape-and-reel. Electrically identical parts.
Is TPS51116RGE discontinued?
No — DDR power solutions remain in active production serving the DDR3/DDR4 installed base.
Can I use a different package variant?
Only if your PCB land pattern supports it — VQFN variants are footprint-specific.
Do you break reels?
Yes — cut tape from one piece for prototypes.
How fast is shipment?
1–3 days from Hong Kong on stock.
Are automotive-grade variants available?
Ask with the -Q1 suffix and we quote it from our market network.
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 TPS51116RGE or its alternates and release shipments against your build schedule — one agreement instead of repeated spot buys.
