Substitute Part Grouping Explanation

Substitution of the ATMEGA8515L-8PI is determined by strict equivalence across the following critical parameters:

• Core Architecture: AVR processor family
• Memory Configuration: 8KB FLASH, 512 x 8 EEPROM, 512 x 8 RAM
• Operating Frequency: 8MHz
• Supply Voltage Range: 2.7V ~ 5.5V
• I/O Count: 35 pins
• Package Type: 40-DIP through-hole
• Connectivity Interfaces: EBI/EMI, SPI, UART/USART
• Peripheral Set: Brown-out Detect/Reset, POR, PWM, WDT
• Temperature Range: -40°C ~ 85°C

The substitute part ATMEGA8515L-8PU maintains identical electrical and functional specifications. The primary difference is the packaging format: the original part uses 40-PDIP (plastic DIP), while the substitute uses 40-PDIP in tube packaging. Both parts are mechanically and electrically interchangeable in through-hole applications.

Parameter Comparison

Engineering Selection Recommendations

The ATMEGA8515L-8PU serves as a direct functional equivalent to the ATMEGA8515L-8PI. Both parts share identical electrical specifications, memory configuration, and pin assignments. The substitute part offers improved compliance status: ATMEGA8515L-8PU is ROHS3 compliant, whereas the original part is RoHS non-compliant. Both parts maintain REACH unaffected status and identical ECCN and HTSUS classifications.

For new designs or systems requiring RoHS compliance, ATMEGA8515L-8PU is the appropriate selection. For legacy system maintenance where RoHS compliance is not a requirement, either part is functionally equivalent. The packaging difference (tube versus standard DIP packaging) does not affect electrical or mechanical compatibility in through-hole PCB applications.

Frequently Asked Questions (FAQ)

Q: Are ATMEGA8515L-8PI and ATMEGA8515L-8PU pin-compatible?

A: Yes. Both parts use the 40-DIP package with identical pin assignments, voltage levels, and signal definitions. They are directly interchangeable in through-hole PCB designs.

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

A: The primary difference is packaging format and RoHS compliance status. ATMEGA8515L-8PI uses standard DIP packaging, while ATMEGA8515L-8PU uses tube packaging. Additionally, ATMEGA8515L-8PU is ROHS3 compliant, whereas ATMEGA8515L-8PI is RoHS non-compliant.

Q: Can I use ATMEGA8515L-8PU as a direct replacement in existing designs?

A: Yes. The electrical and mechanical specifications are identical. No PCB redesign or firmware modification is required for substitution.
