MT41K1G4DA-107:P Alternatives and Equivalents
DDR3/DDR3L SDRAM · Micron Technology · verified against manufacturer datasheet parameters
MT41K1G4DA-107:P — a DDR3/DDR3L SDRAM part from Micron Technology — 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 MT41K1G4DA-107:P discontinued?
MT41K1G4DA-107:P is a DDR3/DDR3L component from Micron. DDR3 is a mature memory generation: still in production, but individual densities and organizations rotate through allocation as fabs prioritize DDR4/DDR5. Spot pricing moves weekly — quotes carry short validity windows by design.
Pin-to-pin compatible alternatives
"Drop-in" means same package and pinout; other rows are family alternates that need design review.

MT41K1G4DA-107:P vs MT41K1G4DA-107:P TR: 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
- Match density AND organization — a 4Gb x16 and a 4Gb x8 are not interchangeable on a 16-bit bus
- Speed bin (-107 vs -125) must meet your controller's timing requirements
- DDR3L (1.35 V) vs DDR3 (1.5 V) — confirm your memory controller supports the voltage
- Check rank and bank configuration against your controller's supported topology
- Re-run memory controller training/validation after any part change
Where to source MT41K1G4DA-107:P and its alternates
We stock MT41K1G4DA-107:P 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.
MT41K1G4DA-107:P 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
Is MT41K1G4DA-107:P discontinued?
DDR3 remains in production, but specific densities and organizations rotate through allocation. Quotes carry validity windows for this reason.
What does the speed suffix mean?
The -107/-125 codes indicate the speed bin (e.g. DDR3-1866 vs DDR3-1600 class). Your memory controller must support the bin you buy.
x8 vs x16 organization — does it matter?
Critically — a x16 part and a x8 part are not interchangeable on a given bus width. Match the organization to your design.
DDR3 vs DDR3L?
DDR3L runs at 1.35 V (1.5 V compatible); plain DDR3 is 1.5 V only. Confirm your controller.
Are date codes stated?
Yes — every quote states quantity, date code and validity window.
How fast is shipment?
1–3 working days from Hong Kong on stocked lines.
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 MT41K1G4DA-107:P or its alternates and release shipments against your build schedule — one agreement instead of repeated spot buys.
