Exact model identity
RDA is the 1866 Mbps selection, not a shortened PBA offer
For this 4Gb x16 EFR device, RD selects 1866 Mbps and 13-13-13 timing. PBA is the 1600 Mbps, 11-11-11 choice in the same DDR3L ordering table. An offer against an RDA BOM line needs to preserve that speed-bin distinction.
An alternative should be evaluated at the operating point your board actually uses. Confirm the controller's timing configuration and engineering acceptance before changing the part number on the order; matching density and ball count are only the beginning of that review.
Selection boundary
The same RD speed code does not establish the same voltage family
H5TC4G63EFR-RDA belongs to the 1.35V DDR3L family. The similarly named H5TQ4G63EFR-RDC is a 1.5V DDR3 device. Their shared EFR designation, x16 width and 1866 Mbps headline are not proof that either may be fitted to the other's board.
Keep H5TC and H5TQ distinct in a sourcing comparison. Engineering should check the supply rails, reference levels, complete pin assignment and device operating limits against the intended design rather than relying on an abbreviated '4Gb 1866' description.
Before approving the offer
Ordering checks for H5TC4G63EFR-RDA
Retain the low-voltage identity
The offered part must remain H5TC4G63EFR-RDA unless a different full MPN is explicitly approved.
Verify the RD timing set
Check 1866 Mbps with 13-13-13 timing against the qualified controller configuration.
Check the application grade
The A ordering option is commercial; do not borrow a temperature qualification from a neighboring suffix.
Send quantity and destination
Date code, packing and requested delivery date are optional preferences; “No preference” is acceptable. If a quotable source is identified, the written offer separates confirmed quantity, condition, lead time, price and terms from items still pending.
Manufacturer specifications identify the device. Your engineering team confirms system fit; DramTrade confirms the proposed supply in a quotation. An enquiry does not reserve stock.
