Engineering Selection Recommendations

EM6OE16NWAKA-07H (Etron Technology, Inc.) qualifies as a parametric equivalent substitute for NDQ46PFI-7NET TR based on the following criteria:

All critical electrical parameters match exactly: memory technology (SDRAM - DDR4), capacity (4Gbit), organization (256M x 16), interface type (POD), clock frequency (1.333 GHz), access time (18 ns), write cycle time (15 ns), supply voltage (1.14V ~ 1.26V), and operating temperature range (0°C ~ 95°C TC).

Physical compatibility is confirmed: both components use 96-pin TFBGA surface mount packaging with compatible dimensions (7.5x13mm vs. 7.5x13.5mm). The 0.5mm difference in length falls within standard PCB layout tolerances for BGA footprints.

Compliance equivalence is established: both parts maintain ROHS3 compliance and identical MSL rating (3, 168 Hours), ensuring equivalent environmental and handling requirements.

Both components maintain Active product status, confirming ongoing manufacturer support and availability.

Frequently Asked Questions (FAQ)

Q: What determines if a DDR4 memory IC can substitute for the NDQ46PFI-7NET TR?

A: Substitution requires exact equivalence across memory architecture (4Gbit, 256M x 16, POD interface, DDR4 technology), electrical performance (1.333 GHz, 18 ns access time, 15 ns write cycle, 1.14V-1.26V supply), and physical specifications (96-TFBGA, surface mount). All parameters must match; no deviations are permitted.

Q: Is the EM6OE16NWAKA-07H package dimension difference (7.5x13.5mm vs. 7.5x13mm) a compatibility issue?

A: No. The 0.5mm length difference is within standard PCB layout tolerances for 96-pin BGA footprints. Both components use identical pin pitch and ball array configuration, ensuring mechanical and electrical compatibility on the same PCB layout.

Q: Can I use EM6OE16NWAKA-07H as a direct replacement without circuit modifications?

A: Yes. All electrical parameters, voltage requirements, timing specifications, and interface characteristics are identical. No circuit redesign or re-qualification is required for substitution.

Q: Are there any compliance or environmental handling differences between these parts?

A: No. Both components are ROHS3 compliant with identical MSL rating (3, 168 Hours), requiring the same storage, handling, and moisture control procedures.

Q: What is the significance of the POD interface in substitution?

A: POD (Pseudo Open Drain) is a specific DDR4 interface standard. Both the main part and substitute use POD interface, confirming electrical signal compatibility at the system level. Interface type is a non-negotiable substitution criterion.

Q: How do I verify these parts are interchangeable in my specific application?

A: Confirm that your system design specifies DDR4 SDRAM with 4Gbit capacity, 256M x 16 organization, POD interface, 1.333 GHz operation, and 96-TFBGA packaging. If all these specifications match your design requirements, either part is functionally equivalent.
