No further factory orders are being accepted, and the last-time-buy window has closed. There is no official TI-specified replacement for this exact order code, but the MSP430F2xx family includes pin-compatible density variants that may serve as a form-fit-function substitute after a firmware migration. A cross-reference search against the base product number MSP430F2122 will surface the active siblings.

Product details
Frequently asked questions
Is MSP430F2122IRTVR obsolete?
Yes, TI lists the MSP430F2122IRTVR as obsolete. No further factory production is planned. For existing BOM lines, the part can be sourced through independent distribution — submit an RFQ for current availability and pricing.
What is the replacement for MSP430F2122IRTVR?
TI has not published a direct replacement for this order code. Within the MSP430F2xx family, higher-density or different-package variants (e.g., MSP430F2132 or MSP430F2122 in alternate packages) may be pin-compatible but require firmware adjustments. A cross-reference search against base product number MSP430F2122 will show active siblings.
