Key Parameters

Substitute Part Grouping Explanation

Substitution of the LC75853NEHS-E is determined by the following critical parameters:

Core Functional Requirements:

• Display Type: LCD
• Configuration: 126 Segment capability
• Interface: Serial
• Supply Current: 300 µA
• Operating Temperature Range: -40°C ~ 85°C
• Mounting Type: Surface Mount

Package Compatibility Considerations:

• Original package: 64-QIPE (14x14)
• Substitute packages must accommodate 64-pin surface mount configurations
• Physical footprint differences require PCB layout evaluation

The LC75857WS-E from Sanyo meets the core functional requirements for 126-segment LCD driver applications with serial interface operation. While package geometry differs (64-SPQFP/64-SQFP vs. 64-QIPE), both are 64-pin surface mount configurations suitable for equivalent circuit implementations.

Parameter Comparison

Engineering Selection Recommendations

Functional Equivalence: The LC75857WS-E provides functional equivalence for 126-segment LCD driver applications with serial interface requirements. Both parts operate within identical temperature ranges and supply current specifications, supporting equivalent system performance.

Compliance Status: Both the LC75853NEHS-E and LC75857WS-E are classified as obsolete products. The LC75857WS-E carries RoHS3 compliance certification, whereas the LC75853NEHS-E is REACH Unaffected. Both share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Supply Voltage Consideration: The LC75857WS-E supports a wider supply voltage range (2.7V ~ 6V) compared to the LC75853NEHS-E (4.5V ~ 6V), providing additional operational flexibility in lower-voltage system designs.

Package Transition: Substitution requires PCB layout modification due to package geometry differences. The LC75857WS-E uses 64-SPQFP (10x10) or 64-SQFP packaging versus the original 64-QIPE (14x14) configuration. Pin-to-pin functional mapping must be verified against device datasheets prior to implementation.

Frequently Asked Questions (FAQ)

Q: Can the LC75857WS-E directly replace the LC75853NEHS-E without PCB modifications?

A: No. While both are 64-pin surface mount devices, the package geometries differ significantly (14x14 mm versus 10x10 mm). PCB footprint redesign is required. Pin functionality must be verified against manufacturer datasheets to ensure correct signal mapping.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is based on: LCD display type, 126-segment configuration capability, serial interface protocol, 300 µA supply current, -40°C to 85°C operating temperature range, and surface mount mounting type. Package differences require engineering evaluation but do not preclude functional substitution.

Q: Are there supply voltage compatibility concerns?

A: The LC75857WS-E operates across 2.7V ~ 6V, while the LC75853NEHS-E requires 4.5V ~ 6V. Systems designed for the original part's minimum voltage (4.5V) are compatible with the substitute. Systems operating below 4.5V cannot use the LC75853NEHS-E but can use the LC75857WS-E.

Q: What compliance certifications apply to the substitute part?

A: The LC75857WS-E is RoHS3 compliant. Both parts share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications. Regulatory requirements for your specific application should be verified independently.

Q: Why are both parts classified as obsolete?

A: Obsolete status indicates these parts are no longer manufactured or supported by their respective manufacturers. Availability is limited to existing inventory. Long-term system designs should evaluate current-generation LCD driver alternatives.
