Substitute Part Grouping Explanation

Substitution of the ATMEGA164PA-MUR is determined by strict equivalence across the following critical parameters: core processor architecture (AVR), core size (8-Bit), clock speed (20MHz), program memory capacity (16KB FLASH), RAM capacity (1K x 8), EEPROM capacity (512 x 8), supply voltage range (1.8V ~ 5.5V), I/O count (32 pins), connectivity interfaces (I2C, SPI, UART/USART), integrated peripherals (Brown-out Detect/Reset, POR, PWM, WDT), data converter specifications (A/D 8x10b), package type (44-VQFN with exposed pad), and compliance certifications (RoHS3, REACH Unaffected).

The ATMEGA164A-MUR qualifies as a parametric equivalent because it maintains identical electrical specifications, memory configuration, peripheral set, and package footprint. The only difference is the packaging format: the main part is supplied in Tape & Reel (TR) format, while the substitute is available in Cut Tape (CT) format. Both parts share the same base product number (ATMEGA164) and are manufactured by Microchip Technology with active product status.

Parameter Comparison

Engineering Selection Recommendations

The ATMEGA164A-MUR is a direct parametric equivalent to the ATMEGA164PA-MUR for all electrical, functional, and mechanical specifications. Both parts maintain active product status from Microchip Technology and carry identical RoHS3 and REACH compliance certifications. The distinction between these parts is limited to packaging format: Tape & Reel (TR) versus Cut Tape (CT). Selection between these variants depends on manufacturing process requirements and component handling infrastructure. Tape & Reel packaging is standard for automated pick-and-place assembly operations, while Cut Tape packaging is suitable for manual assembly, prototyping, or lower-volume production runs. Both packaging formats contain components with identical MSL ratings (3, 168 Hours) and require equivalent moisture control during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can ATMEGA164A-MUR be used as a direct replacement for ATMEGA164PA-MUR in production?

A: Yes. The ATMEGA164A-MUR is electrically and functionally identical to the ATMEGA164PA-MUR. The only difference is packaging format (Cut Tape versus Tape & Reel). If your assembly process accommodates Cut Tape format, this part is a direct substitute.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on a continuous reel suitable for automated assembly equipment. Cut Tape (CT) packaging provides the same components cut from the reel into smaller quantities, typically used for manual assembly, prototyping, or lower-volume production. Both formats contain identical components with the same electrical specifications and compliance certifications.

Q: Are there any compatibility concerns when switching between ATMEGA164PA-MUR and ATMEGA164A-MUR?

A: No compatibility concerns exist. Both parts share identical pin configurations, electrical characteristics, memory specifications, and peripheral functionality. PCB layout, firmware, and system design remain unchanged.

Q: Do both parts have the same moisture sensitivity requirements?

A: Yes. Both ATMEGA164PA-MUR and ATMEGA164A-MUR carry MSL rating 3 (168 Hours), requiring identical moisture control protocols during storage, handling, and assembly.

Q: Which part should I specify for high-volume automated assembly?

A: The ATMEGA164PA-MUR in Tape & Reel format is optimized for high-volume automated pick-and-place assembly. The ATMEGA164A-MUR in Cut Tape format is suitable for lower-volume or manual assembly processes.

Q: Are both parts RoHS3 compliant?

A: Yes. Both ATMEGA164PA-MUR and ATMEGA164A-MUR are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
