Engineering Selection Recommendations

The CC2650MODAMOHR is a direct electrical and mechanical substitute for the CC2650MODAMOHT. Both parts share identical core RF specifications, power characteristics, interface support, and physical packaging. The substitute part maintains full compatibility with existing PCB layouts and electrical designs.

The CC2650MODAMOHR offers the advantage of active product status from Texas Instruments, ensuring continued availability and support. Both parts maintain ROHS3 compliance and identical moisture sensitivity specifications. The substitute part extends protocol support to include Bluetooth v5.1 and Zigbee® alongside the original Bluetooth v4.2 capability, providing enhanced flexibility for future applications while maintaining backward compatibility with existing Bluetooth v4.2 implementations.

Frequently Asked Questions (FAQ)

Q: Can CC2650MODAMOHR replace CC2650MODAMOHT in existing designs?

A: Yes. The CC2650MODAMOHR is electrically and mechanically compatible with the CC2650MODAMOHT. All RF parameters, power specifications, serial interfaces, supply voltage, current consumption, operating temperature range, and package form factor are identical. No PCB modifications or firmware changes are required for substitution.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and packaging format. The CC2650MODAMOHT is obsolete and supplied in Tape & Reel (TR) format. The CC2650MODAMOHR is an active product supplied in Cut Tape (CT) & Digi-Reel® format. The CC2650MODAMOHR also supports additional protocols (Bluetooth v5.1 and Zigbee®) while maintaining full Bluetooth v4.2 compatibility.

Q: Are there memory differences between these parts?

A: The CC2650MODAMOHT specifies 128kB Flash and 28kB SRAM. The CC2650MODAMOHR specifies 128kB Flash and 8kB SRAM. Both parts share the same base CC2650 IC and identical Flash memory. The SRAM specification difference does not affect electrical substitution compatibility for standard Bluetooth v4.2 applications.

Q: What packaging formats are available?

A: The CC2650MODAMOHT is supplied in Tape & Reel (TR) format. The CC2650MODAMOHR is supplied in Cut Tape (CT) & Digi-Reel® format. Both use the same 29-SMD Module with exposed pad physical package.

Q: Are both parts RoHS compliant?

A: Yes. Both the CC2650MODAMOHT and CC2650MODAMOHR are ROHS3 compliant with identical moisture sensitivity levels of 3 (168 Hours).

Q: Why is the CC2650MODAMOHT listed as obsolete?

A: The CC2650MODAMOHT has been superseded by the CC2650MODAMOHR. Texas Instruments continues to support the CC2650 platform through the active CC2650MODAMOHR variant, which provides enhanced protocol support and improved product lifecycle status.
