Substitute Part Grouping Explanation

Substitution of the ATTINY26L-8PI is determined by strict equivalence across all electrical and mechanical parameters. The substitute part ATTINY26L-8PU maintains identical specifications in the following critical areas:

• Core processor architecture (AVR)
• Memory configuration (2KB FLASH, 128 bytes EEPROM, 128 bytes RAM)
• Operating frequency (8MHz)
• I/O pin count (16)
• Supply voltage range (2.7V ~ 5.5V)
• Peripheral feature set (Brown-out Detect/Reset, POR, PWM, WDT)
• Operating temperature range (-40°C ~ 85°C)
• Physical package format (20-DIP, 0.300", 7.62mm)

The only differences between the main part and substitute are packaging format (tube vs. standard) and product status (obsolete vs. active), with the substitute offering improved RoHS compliance (ROHS3 Compliant vs. RoHS non-compliant).

Parameter Comparison

Engineering Selection Recommendations

The ATTINY26L-8PU is the direct equivalent substitute for the ATTINY26L-8PI. Selection of the substitute part is justified by the following factors:

• The ATTINY26L-8PI is classified as obsolete, limiting availability for new production and long-term supply chain continuity.
• The ATTINY26L-8PU maintains active product status, ensuring ongoing availability and manufacturer support.
• The substitute part achieves ROHS3 compliance, meeting current environmental and regulatory requirements, whereas the main part is RoHS non-compliant.
• All electrical specifications, memory configurations, I/O capabilities, and peripheral functions are identical between the two parts.
• Both parts utilize the same 20-DIP package format with identical pin assignments and mechanical dimensions.
• The substitute part is available in tube packaging, which is standard for active production components.

Frequently Asked Questions (FAQ)

Q: Can the ATTINY26L-8PU be used as a direct replacement for the ATTINY26L-8PI in existing designs?

A: Yes. The ATTINY26L-8PU is electrically and mechanically identical to the ATTINY26L-8PI. All pin assignments, electrical characteristics, memory specifications, and operating parameters are equivalent. No circuit modifications are required.

Q: What is the difference between the ATTINY26L-8PI and ATTINY26L-8PU?

A: The primary differences are product status and compliance certification. The ATTINY26L-8PI is obsolete and RoHS non-compliant, while the ATTINY26L-8PU is active and ROHS3 compliant. Packaging format also differs (standard vs. tube). All functional and electrical specifications are identical.

Q: Why is the ATTINY26L-8PI classified as obsolete?

A: Microchip Technology has discontinued the ATTINY26L-8PI in its standard packaging format. The ATTINY26L-8PU represents the active equivalent in tube packaging with current compliance certifications.

Q: Are there any compatibility issues when switching from ATTINY26L-8PI to ATTINY26L-8PU?

A: No compatibility issues exist. Both parts share identical pinouts, electrical specifications, and functional capabilities. The 20-DIP package format is the same for both parts.

Q: What does ROHS3 compliance mean for the ATTINY26L-8PU?

A: ROHS3 compliance indicates the part meets the Restriction of Hazardous Substances Directive requirements, restricting the use of specific hazardous materials in electrical and electronic equipment. This certification is required for many applications and markets.

Q: Is the ATTINY26L-8PU available in the same quantities as the ATTINY26L-8PI?

A: Availability varies based on current inventory and production schedules. The ATTINY26L-8PU is an active product with ongoing manufacturing, whereas the ATTINY26L-8PI is obsolete with limited remaining stock.
