Substitute Part Grouping Explanation

Substitution of the ATMEGA168V-10PI is determined by strict equivalence across the following critical parameters:

• Core Architecture: AVR processor family
• Memory Configuration: 16KB FLASH, 1KB RAM, 512 bytes EEPROM
• Operating Frequency: 10MHz
• Supply Voltage Range: 1.8V ~ 5.5V
• I/O Count: 23 pins
• Peripheral Set: I2C, SPI, UART/USART, PWM, WDT, brown-out detection
• Package Type: 28-DIP through-hole form factor
• Temperature Range: -40°C ~ 85°C

The ATMEGA168PV-10PU meets all these criteria, providing functional and electrical equivalence while maintaining identical pinout and package dimensions.

Parameter Comparison

Engineering Selection Recommendations

The ATMEGA168PV-10PU is the direct equivalent substitute for the ATMEGA168V-10PI. Both devices share identical electrical specifications, memory configuration, peripheral functionality, and 28-DIP package dimensions. The primary distinction is product status: the original part is obsolete while the substitute remains in active production. Both parts carry equivalent export classifications (ECCN EAR99) and tariff codes (HTSUS 8542.31.0001), ensuring regulatory consistency. The substitute offers superior availability and supply chain continuity for new designs and ongoing production requirements.

Frequently Asked Questions (FAQ)

Q: Are the ATMEGA168V-10PI and ATMEGA168PV-10PU pin-compatible?

A: Yes. Both devices use the 28-DIP package with identical pinout and pin assignments. Direct socket substitution is possible without circuit modification.

Q: Can I use the ATMEGA168PV-10PU as a drop-in replacement in existing designs?

A: Yes. The substitute part maintains electrical equivalence across all specified parameters including supply voltage range (1.8V ~ 5.5V), operating frequency (10MHz), memory configuration, and peripheral functionality. No design changes are required.

Q: What is the difference between the ATMEGA168V-10PI and ATMEGA168PV-10PU?

A: The parts are functionally equivalent. The primary differences are manufacturer designation (Microchip Technology vs. Atmel) and product status (obsolete vs. active). The "V" and "PV" designations indicate different voltage grade classifications within the ATMEGA168 family, but both operate within the same 1.8V ~ 5.5V supply range.

Q: Are there any compliance or certification differences?

A: Both parts carry identical export classifications (ECCN EAR99) and tariff codes (HTSUS 8542.31.0001). No compliance differences exist between the two parts.

Q: Why is the original part listed as obsolete?

A: The ATMEGA168V-10PI is classified as obsolete by the manufacturer. The ATMEGA168PV-10PU remains in active production and is the recommended source for new component procurement.
