PCA85133U/2DB/Q1Z Equivalent & Substitute Parts

Part Overview

The PCA85133U/2DB/Q1Z is an LCD driver die manufactured by NXP USA Inc., designed for display applications supporting 7-segment, 14-segment, and dot matrix configurations. This component operates as an I2C interface driver capable of controlling up to 320 display elements across multiple character formats.

The main part carries an Obsolete product status, which necessitates identification of active equivalent alternatives to ensure supply chain continuity and long-term design reliability. The substitute part maintains identical electrical and mechanical specifications while offering improved availability through active production status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PCA85133U/2DB/Q1Z is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Supply voltage range (1.8V ~ 5.5V), supply current (50 mA), and I2C interface protocol must remain identical to ensure circuit compatibility without redesign.

Functional Specifications: Display configuration support (7 Segment + DP, 14 Segment + DP + AP, Dot Matrix), character/element capacity (20 Characters, 40 Characters, 320 Elements), and LCD driver functionality must be preserved.

Environmental & Compliance: Operating temperature range (-40°C ~ 95°C), automotive grade classification, AEC-Q100 qualification, ROHS3 compliance, and REACH unaffected status ensure regulatory and reliability requirements are maintained.

Physical Form: Die package and surface mount mounting type must match to maintain integration compatibility.

The substitute part PCA85133U/2DA/Q1Z meets all these criteria while differing only in packaging format (Tray versus unspecified) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The PCA85133U/2DA/Q1Z serves as the direct equivalent for the obsolete PCA85133U/2DB/Q1Z. Both components share identical electrical, functional, and environmental specifications, with full compatibility across all specified display configurations and interface protocols.

Selection of the substitute part is justified by its Active product status, ensuring continued availability and manufacturing support. Both parts maintain AEC-Q100 automotive qualification and ROHS3 compliance, satisfying regulatory requirements for automotive and industrial applications.

The only distinction between the parts is the packaging format (Tray for the substitute), which does not affect electrical or functional performance. This difference is a supply chain consideration rather than a technical limitation.

Frequently Asked Questions (FAQ)

Q: Can PCA85133U/2DA/Q1Z directly replace PCA85133U/2DB/Q1Z in existing designs?
