W3J128M72G-800LBI Technical Overview: Verified Parameters Before Sourcing
WEDC W3J128M72G-800LBI is a memory device cataloged in Memory & Storage for Aerospace & Defense, Satellite & Space programs. Unlike a family-level listing, the complete ordering code matters: package, temperature grade, speed option, screening level and shipment format can change with a suffix. The structured reference data for this exact part identifies Memory Type DDR3 SDRAM multi-chip package, Density 1 GB (8 Gbit), Organization 128M × 72, one rank, Data Rate 800 Mb/s.
These values are useful for initial BOM and sourcing review, but engineering approval should still use the latest manufacturer-controlled datasheet, package drawing and change notices. For availability, lot/date code and documentation, send Sparkle Electronics the complete W3J128M72G-800LBI requirement.

What the Specifications Mean in a Design Review
For this memory device, the main compatibility checks are density, organization, bus width, access time, voltage, interface timing and package pinout. A replacement should not be approved from the family name alone. The values below need to be checked against the schematic, PCB footprint, power tree, timing constraints, thermal analysis and program qualification baseline:
- Memory Type: DDR3 SDRAM multi-chip package
- Density: 1 GB (8 Gbit)
- Organization: 128M × 72, one rank
- Data Rate: 800 Mb/s
- Temperature Grade: Industrial
- Package/Case: 375-ball low-profile PBGA
- Supply Voltage: 1.5 V
Minimum and maximum values are not interchangeable with typical test values, and package-level compatibility does not guarantee pin, timing or firmware compatibility. Where the assembly is used in high-reliability equipment, confirm the required screening, traceability, lead finish and environmental documentation before purchase.
W3J128M72G-800LBI and Related WEDC Devices
The following pages provide useful internal comparison points. They are related sourcing options, not automatically drop-in replacements:
- WEDC EDI88512CA20NI — compare the exact architecture, package, speed or grade before substitution.
- WEDC W3H64M72E-400BI — compare the exact architecture, package, speed or grade before substitution.
- WEDC WF1M32B-100G2UM3 — compare the exact architecture, package, speed or grade before substitution.
- WEDC EDI8L32512C12AC — compare the exact architecture, package, speed or grade before substitution.
When comparing these devices, start with the exact function and architecture, then verify package and pinout, voltage rails, speed or bandwidth, operating temperature and qualification grade. If any of those differ, an engineering redesign or requalification may be required.
Package, Temperature and Ordering-Code Checks
The orderable code W3J128M72G-800LBI must be kept intact on the RFQ. Confirm the manufacturer marking, package drawing, terminal finish, moisture handling, operating-temperature requirement and packing format. For obsolete or long-stored material, define acceptable date codes and inspection criteria before quotation rather than after delivery.
Sourcing teams should also request the documentation appropriate to the program: Certificate of Conformance, packing and label photographs, lot/date-code information, traceability, visual inspection, X-ray or electrical testing when required. See our quality-control approach and the broader Memory & Storage selection.
Applications and Procurement Context
W3J128M72G-800LBI may be evaluated for Aerospace & Defense, Satellite & Space systems where its verified electrical limits, package and temperature range match the approved design. Typical work includes new production, repair, lifecycle extension and last-time-buy planning. Application labels describe catalog relevance; final suitability remains a system-level engineering decision.
