Key Parameters

Substitute Part Grouping Explanation

Substitutability for the ATMEGA8535L-8PI is determined strictly by matching the following parameters: base product number, package form-factor, core specifications, supply voltage range, operation temperature range, memory capacities, connectivity options, I/O count, and manufacturer. Substitute devices must also align on regulatory compliance, mounting type, and status as reflected in inventory and certifications.

Parameter Comparison

Engineering Selection Recommendations

Substitution is based on matched electrical, mechanical, and operational parameters. The ATMEGA8535L-8PU provides equivalent functionality, identical package, and regulatory alignment with added ROHS3 compliance, while the main part ATMEGA8535L-8PI is RoHS non-compliant. Both models are listed as obsolete and share the same REACH status and unlimited MSL.

Frequently Asked Questions (FAQ)

Q1: What are the substitution criteria for the ATMEGA8535L-8PI?
A1: Substitution is determined by matching base product number, package dimensions, electrical specifications, connectivity options, memory sizes, number of I/O pins, operating temperature range, manufacturer, and compliance designations.

Q2: Can ATMEGA8535L-8PU directly replace ATMEGA8535L-8PI in existing designs?
A2: Both the ATMEGA8535L-8PI and ATMEGA8535L-8PU possess identical mechanical and electrical characteristics, including package, memory configuration, and processor core, supporting direct substitution in matching socket and PCB footprints.

Q3: Does package form factor affect substitute selection within the ATMEGA8535 family?
A3: The substitute part ATMEGA8535L-8PU uses the same 40-PDIP / 40-DIP (0.600", 15.24mm) through-hole format, ensuring compatibility with existing physical layouts.

Q4: Are there differences in regulatory compliance between the main and substitute parts?
A4: The primary distinction is the RoHS status: ATMEGA8535L-8PI is RoHS non-compliant, whereas ATMEGA8535L-8PU is ROHS3 compliant. Both are REACH unaffected and have MSL 1 (Unlimited).
