Summary
Possible alternative for industrial SD NAND (Foresee / Longsys class). Exact competitor ordering PNs are not listed here. Loongtion YIDT* (handbook §7) may replace by SD protocol + LGA package class — verify pin map, capacity, voltage, and firmware on the host.
Parameter alignment
Key handbook fields side by side — confirm package, grade, and firmware against the datasheet for your build.
| Parameter | Loongtion | Industrial SD NAND (Foresee / Longsys class) |
|---|---|---|
| Interface | SD 3.0 / 2.0 | SD 2.0 / 3.0 (verify) |
| Package | LGA8 (12.5×9 mm) | LGA / FBGA SD NAND (verify map) |
| Capacity | 8 / 16 / 32 / 64 GB | Series-dependent |
| Temperature | −40°C to +85°C | Often −25~+85°C or WT — verify |
Why evaluate Loongtion for this PN
Cross-reference is not only for discontinued parts — many OEMs qualify a Loongtion path as a second source next to Industrial SD NAND (Foresee / Longsys class), then use it for dual-sourcing, allocation relief, or future EOL coverage.
- Second source — not only an EOL story Use this mapping to dual-source alongside Industrial SD NAND (Foresee / Longsys class). Qualify Loongtion once so allocation, long lead times, or a future EOL on Industrial SD NAND LGA family does not stop your line.
- Possible Alternative — Verify path for BOM review This page documents the Loongtion PN, key parameter alignment, and compatibility type. Treat it as engineering guidance — confirm package, speed/firmware, and temperature on your host before production.
- Industrial temperature grades where listed Loongtion lists −40°C to +85°C for this line. Match the ordering PN to your environmental requirement (commercial, wide-temp, or Extreme-temp / GJB where offered).
- Direct engineering and small-batch pilots Request the datasheet with your incumbent PN, board, and temperature grade. Typical engineering reply is within one business day on China business days — useful for pilots before you lock an AVL dual-source.
Typical applications
Common equipment contexts where engineers search for this part family or a compatible alternative.
- Solder-down raw NAND designs
- Industrial storage controllers
- Long-lifecycle embedded systems
FAQs for this cross-reference
What does “Possible Alternative — Verify” mean for Industrial SD NAND LGA family?
We do not publish a single verified ordering PN for every incumbent SKU in this family. Loongtion YIDT008TUS-S / YIDT016TUS-S / YIDT032TUT-S / YIDT064TUT-S is a possible alternative by protocol / form factor / density class — host verification is required before production. Send your exact BOM PN and we will shortlist the closest Loongtion part.
Is this a guaranteed drop-in?
No. Treat this page as a starting point for dual-sourcing or EOL exploration. Confirm package/ball map, firmware, capacity, temperature, and endurance on your board. Engineering can help once you share the exact incumbent ordering code.
What should I send so you can verify a match?
Incumbent full ordering PN (not only the family name), capacity, temperature grade, form factor or package, interface, and the target host / application. Photos of the part marking or a datasheet excerpt help.
Can I request a quote after verification?
Yes. After we confirm the closest Loongtion PN against your BOM line, send the board name, temperature grade, and quantity for a quote.
