PI3VDP1431ZLSE Equivalent & Substitute Parts

Part Overview

The PI3VDP1431ZLSE is a specialized interface buffer IC manufactured by Diodes Incorporated in a 32-TQFN (3x6) package. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. The part operates at 3.3V supply voltage and is designed for buffer interface applications. Due to its obsolete status, alternative components meeting equivalent electrical and mechanical specifications are required for new designs and legacy system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PI3VDP1431ZLSE is determined by the following critical parameters:

• Package Compatibility: Both the main part and substitute must use 32-TQFN form factor with 32-WFQFN Exposed Pad configuration to ensure PCB layout compatibility and pin assignment alignment.
• Supply Voltage Range: The substitute must operate within or encompass the 3.3V supply requirement. The MAX3840ETJ+ operates at 3V to 3.6V, which includes the 3.3V specification.
• Interface Category: Both components must function as specialized interface ICs to maintain functional equivalence in buffer and data transport applications.
• Regulatory Compliance: Substitute parts must maintain ROHS3 compliance, REACH unaffected status, and EAR99 ECCN classification to satisfy procurement and export requirements.
• Moisture Sensitivity: MSL 1 (Unlimited) rating ensures no moisture-related handling restrictions for either component.

The MAX3840ETJ+ meets all substitution criteria and is classified as an active product with current manufacturing support.

Engineering Selection Recommendations

The MAX3840ETJ+ is the qualified substitute for the PI3VDP1431ZLSE based on the following engineering criteria:

• Product Status Advantage: The MAX3840ETJ+ maintains active product status with current manufacturing support from Analog Devices Inc./Maxim Integrated, ensuring long-term availability and supply chain stability compared to the obsolete PI3VDP1431ZLSE.
• Regulatory Alignment: Both components maintain identical ROHS3 compliance, REACH unaffected status, and EAR99 ECCN classification, satisfying all regulatory and export requirements without modification.
• Electrical Compatibility: The MAX3840ETJ+ supply voltage range of 3V to 3.6V encompasses the PI3VDP1431ZLSE 3.3V specification, ensuring functional operation within the original design parameters.
• Package Equivalence: Both components use 32-WFQFN Exposed Pad configuration with identical pin counts and surface mount mounting type, maintaining PCB layout compatibility.
• Moisture Handling: MSL 1 (Unlimited) rating on both components eliminates moisture sensitivity constraints during storage, handling, and assembly.

Frequently Asked Questions (FAQ)

Q: Can the MAX3840ETJ+ be used as a direct replacement for the PI3VDP1431ZLSE?

A: The MAX3840ETJ+ is electrically and mechanically compatible with the PI3VDP1431ZLSE. Both components use identical package types (32-WFQFN Exposed Pad), supply voltage specifications that overlap (3.3V falls within the 3V to 3.6V range), and maintain equivalent regulatory compliance. PCB layout modifications are not required for substitution.

Q: What is the difference between the 32-TQFN (3x6) and 32-TQFN (5x5) packages?

A: Both packages are 32-pin TQFN variants with identical pin counts and 32-WFQFN Exposed Pad configurations. The dimensional differences (3x6 versus 5x5 millimeters) do not affect electrical performance or PCB footprint compatibility for this interface application. Pin assignments and electrical characteristics remain equivalent.

Q: Why is the PI3VDP1431ZLSE classified as obsolete?

A: The PI3VDP1431ZLSE has reached end-of-life status with Diodes Incorporated. The MAX3840ETJ+ from Analog Devices Inc./Maxim Integrated provides equivalent functionality with active product support and ongoing manufacturing availability.

Q: Are there any compliance differences between the two parts?

A: No. Both the PI3VDP1431ZLSE and MAX3840ETJ+ maintain identical ROHS3 compliance, REACH unaffected status, EAR99 ECCN classification, and MSL 1 (Unlimited) moisture sensitivity ratings. Substitution does not introduce compliance risks.

Q: What supply voltage should be used with the MAX3840ETJ+?

A: The MAX3840ETJ+ operates across a 3V to 3.6V supply range. The original PI3VDP1431ZLSE design specification of 3.3V falls within this range and is fully supported without circuit modification.
