Obsolete — sourcing reality for this BGA MSP430
The MSP430F5438AIZQWT is officially marked obsolete by Texas Instruments. No last-time-buy window remains open through the factory channel. For a BOM line that needs this exact order code — perhaps a legacy board in field service or a production run that cannot requalify a new MCU — the only supply path is the independent surplus and broker market. We source and quote this part to order against an RFQ; availability and current pricing are confirmed at quote time. The scorch mark tells you: once the last surplus reel is gone, this BGA footprint has no pin-compatible second source within the MSP430F5xx family that matches the same ball map.
