Equivalent & Alternatives
The following parts are listed as comparable options for similar wireless microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MKW36A512VHT4 | Same silicon die, 48-pin LQFN (non-wettable flank), no AOI support | Suitable for non-automotive or cost-sensitive industrial BLE nodes where solder joint inspection is not mandated | Select when IATF 16949 AOI compliance is unnecessary and LQFN footprint compatibility exists. |
| MKW34A512VFT4 | Omits FlexCAN and second LPUART; retains BLE 5.0, 512 KB flash, wettable HVQFN | Targeted at non-CAN automotive sensors (e.g., seat occupancy, ambient light) requiring BLE but no vehicle bus integration | Choose when CAN FD connectivity is excluded from system architecture and BOM cost reduction is prioritized. |
Compared with MKW36A512VFT4, MKW36A512VHT4 offers identical RF/MCU performance but lacks wettable flanks for automotive AOI, while MKW34A512VFT4 removes FlexCAN and one LPUART to reduce cost - making MKW36A512VFT4 the only option combining full CAN FD, dual-LIN-capable UART, and wettable-flank packaging for Tier 1 digital key modules.
