AY0438T-I/L LCD Driver Equivalent & Substitute Parts

Part Overview

The AY0438T-I/L is a 32-segment LCD driver IC manufactured by Microchip Technology, designed for parallel interface LCD applications requiring 16-character display capability. This component operates as a Power Management (PMIC) device in surface mount configuration using a 44-LCC (J-Lead) package. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified to provide alternative sourcing options when the primary packaging format (Cut Tape with Digi-Reel) is unavailable or when alternative inventory channels are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AY0438T-I/L is determined by strict equivalence across the following critical parameters:

• Display Type: LCD
• Configuration: 32 Segment
• Interface: Parallel
• Digits or Characters: 16 Characters
• Current - Supply: 25 µA
• Voltage - Supply: 3V ~ 8.5V
• Operating Temperature: -40°C ~ 85°C
• Mounting Type: Surface Mount
• Package / Case: 44-LCC (J-Lead)
• Supplier Device Package: 44-PLCC (16.59x16.59)

The identified substitute part AY0438-I/L maintains identical electrical and mechanical specifications. The primary distinction between the main part and substitute is the packaging format: the main part is supplied in Cut Tape with Digi-Reel, while the substitute is supplied in Tube packaging. Both parts share the same base product number (AY0438) and are manufactured by Microchip Technology with Active product status.

Parameter Comparison

Engineering Selection Recommendations

Both the AY0438T-I/L and AY0438-I/L are Active products manufactured by Microchip Technology with identical electrical and mechanical specifications. Selection between these parts should be based on packaging and supply chain requirements:

The AY0438T-I/L in Cut Tape with Digi-Reel packaging is suitable for high-volume automated assembly operations requiring continuous reel feeding. The AY0438-I/L in Tube packaging is appropriate for lower-volume applications or when reel-based handling infrastructure is unavailable. Both parts maintain full RoHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity rating, ensuring equivalent regulatory and environmental performance in end-use applications.

Frequently Asked Questions (FAQ)

Q: Can AY0438-I/L be used as a direct replacement for AY0438T-I/L?

A: Yes. Both parts are electrically and mechanically identical, sharing the same base product number, manufacturer, and all critical specifications including display type, segment configuration, interface protocol, supply voltage range, operating temperature range, and physical package dimensions.

Q: What is the difference between Cut Tape with Digi-Reel and Tube packaging?

A: Cut Tape with Digi-Reel is a continuous reel format designed for automated pick-and-place assembly equipment. Tube packaging contains individual components in a plastic tube, suitable for manual handling or lower-volume assembly processes. The electrical and mechanical properties of the component remain unchanged regardless of packaging format.

Q: Are there any compatibility considerations when switching between these packaging formats?

A: No compatibility issues exist at the component level. The 44-LCC (J-Lead) package and 44-PLCC (16.59x16.59) physical dimensions are identical. Assembly process adjustments may be required depending on whether your production line uses automated reel-fed equipment or manual component placement, but the component itself functions identically in both cases.

Q: Do both parts meet the same compliance standards?

A: Yes. Both AY0438T-I/L and AY0438-I/L are ROHS3 compliant, REACH unaffected, and carry unlimited moisture sensitivity rating (MSL 1). Regulatory and environmental compliance is equivalent across both parts.

Q: What supply voltage range is supported by these LCD drivers?

A: Both parts operate across a 3V to 8.5V supply voltage range, providing flexibility for integration into systems with varying power supply architectures.
