AY0438T/L Equivalent & Substitute Parts Reference

Part Overview

The AY0438T/L from Microchip Technology is an active power management IC (PMIC), specifically designed as an LCD driver capable of controlling 32 segments. It is packaged in a 44-PLCC (16.59x16.59 mm) surface mount format and supports parallel interface operation for LCD display applications requiring 16 characters. Given the potential variation in packaging, supply format, or product inventory, identifying approved substitutes with identical electrical and mechanical specifications is vital for uninterrupted production and maintenance cycles.

Parameter Comparison

Engineering Selection Recommendations

Both AY0438T/L and AY0438/L are classified as active products and exhibit complete alignment in their electrical, mechanical, and compliance characteristics, including RoHS3, REACH, ECCN, and MSL specifications. Given the identical manufacturer, product status, and type, direct substitution between these LCD driver PMICs does not impact compliance, certification, or operational requirements under the provided parameters.

Frequently Asked Questions (FAQ)

Q1: Which parameters are critical for verifying PMIC LCD driver substitution?
A1: Substitution is validated based on manufacturer, segment configuration, supply voltage and current, display type, interface, mounting style, package type, and regulatory compliance.

Q2: Are AY0438T/L and AY0438/L directly interchangeable for surface mount assemblies?
A2: Both products utilize identical 44-PLCC (16.59x16.59 mm) surface mount packaging, supporting full mechanical interchangeability.

Q3: Does the packaging format (Tape & Reel vs Tube) affect the electrical or mechanical compatibility?
A3: The packaging format only influences how the part is supplied for assembly processes. It does not alter the electrical or mechanical parameters of the components.

Q4: Are RoHS3, REACH, and ECCN certifications maintained across the substitute?
A4: Both AY0438T/L and AY0438/L are ROHS3 compliant, REACH unaffected, and classified as EAR99 for ECCN, ensuring regulatory compliance.

Q5: Is there any difference in operating temperature or supply ratings between the substitutes?
A5: Operating temperature (0°C ~ 70°C), supply current (25 µA), and voltage range (3V ~ 8.5V) are consistent across both part numbers as provided.
