Substitute Part Grouping Explanation

Substitution of the MSP430F1101IPW is determined by strict equivalence across the following critical parameters:

• Core processor architecture (MSP430 CPU16)
• Core size (16-Bit)
• Operating frequency (8MHz)
• Program memory capacity and type (1KB FLASH)
• RAM capacity (128 x 8)
• Supply voltage range (1.8V ~ 3.6V)
• I/O pin count (14)
• Integrated peripherals (POR, WDT)
• Data converter type (Slope A/D)
• Package form factor (20-TSSOP)
• Operating temperature range (-40°C ~ 85°C)

The MSP430F1101AIPW qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility across all parameters listed above.

Parameter Comparison

Engineering Selection Recommendations

The MSP430F1101AIPW is the direct equivalent substitute for the MSP430F1101IPW. Both devices are manufactured by Texas Instruments and share identical electrical and mechanical specifications.

The primary distinction is product status: the MSP430F1101IPW is classified as Obsolete, while the MSP430F1101AIPW is Active. For new designs or ongoing production requiring this microcontroller specification, the MSP430F1101AIPW is the appropriate selection due to its active product status and assured long-term availability.

Both parts maintain ROHS3 compliance, REACH unaffected status, and identical regulatory classifications (ECCN: EAR99, HTSUS: 8542.31.0001), ensuring compatibility with environmental and trade compliance requirements.

Frequently Asked Questions (FAQ)
