Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LC75806PTS-T-H is determined by the following critical parameters:

Package Compatibility: Both substitute parts must use the 100-TQFP (14x14) surface mount package to ensure PCB footprint compatibility without redesign.

Interface Type: Serial interface requirement must be maintained across all substitute candidates.

Display Type: LCD driver functionality is mandatory for all equivalents.

Operating Temperature Range: The -40°C to 85°C operating range establishes the minimum environmental specification for substitutes.

Voltage Supply Range: Supply voltage compatibility within the 4.5V to 6V window is required for direct circuit integration.

RoHS and Compliance: ROHS3 compliance and REACH unaffected status ensure regulatory alignment with the original component.

The identified substitute parts meet these core substitution criteria while maintaining functional equivalence for LCD driver applications.

Parameter Comparison

Engineering Selection Recommendations

BU91530KVT-ME2 (Rohm Semiconductor): This substitute is an active product with automotive grade qualification and AEC-Q100 certification. It operates within an extended lower voltage range (2.7V minimum) and demonstrates significantly lower supply current consumption at 130 µA compared to the 1.4 mA of the main part. The 445-segment configuration provides expanded display capability. This part is suitable for applications requiring active product status and automotive-grade reliability.

LC75806PT-H (onsemi): This substitute maintains identical electrical specifications and segment configuration to the main part (231/304 segment, 1.4 mA supply current, 4.5V ~ 6V supply voltage). Both parts share the same base product number (LC75806) and are from the same manufacturer. This part is classified as obsolete, matching the status of the main component. Selection of this substitute is appropriate when maintaining exact electrical and functional parity with the original design is required.

Frequently Asked Questions (FAQ)

Q: Can the BU91530KVT-ME2 be used as a direct replacement for the LC75806PTS-T-H?

A: The BU91530KVT-ME2 shares the same 100-TQFP package, serial interface, and operating temperature range. However, it supports a higher segment count (445 vs. 231/304) and operates at lower supply current (130 µA vs. 1.4 mA). Compatibility depends on whether the application circuit can accommodate the different segment configuration and lower current draw.

Q: What is the difference between LC75806PT-H and LC75806PTS-T-H?

A: Both parts are onsemi LCD drivers with identical electrical specifications, segment configurations, and package types. The primary difference is in the packaging designation suffix. The LC75806PT-H is functionally equivalent and maintains the same 231/304 segment configuration and 1.4 mA supply current.

Q: Are all three parts available in the same package?

A: Yes, all three parts use the 100-TQFP (14x14) surface mount package, ensuring PCB footprint compatibility without layout redesign.

Q: What is the significance of the BU91530KVT-ME2 automotive qualification?

A: The BU91530KVT-ME2 carries AEC-Q100 automotive qualification and automotive grade designation. This certification indicates compliance with automotive industry reliability and quality standards. Selection of this part is appropriate for applications requiring automotive-grade components.

Q: How does the lower supply current of the BU91530KVT-ME2 affect circuit design?

A: The BU91530KVT-ME2 operates at 130 µA supply current compared to 1.4 mA for the LC75806PTS-T-H. This lower current consumption may reduce power supply requirements and heat dissipation in the application circuit. Circuit validation is necessary to confirm compatibility with existing power delivery infrastructure.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all three parts (LC75806PTS-T-H, BU91530KVT-ME2, and LC75806PT-H) are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
