LC75808W-E Equivalent & Substitute Parts

Part Overview

The LC75808W-E is an LCD driver IC manufactured by onsemi, designed for segment-based LCD display applications supporting 480, 540, or 600 segment configurations. This device operates as a serial interface LCD driver in a 100-SQFP surface mount package. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, legacy device replacement, and design continuity in applications where this driver remains in use.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LC75808W-E is determined by the following critical parameters:

Primary Substitution Criteria:

• Display driver category and LCD interface type (Serial)
• Package form factor and pin count (100-pin surface mount)
• Operating temperature range compatibility (-40°C ~ 85°C)
• Supply voltage operating window (4.5V ~ 6V for main part)
• Segment or character display configuration support

Secondary Compatibility Factors:

• Moisture sensitivity level (MSL 3)
• Regulatory compliance (REACH, ECCN classification)
• Mounting technology (Surface Mount)

The LC75812PTH-8565-H represents a related LCD driver from the same manufacturer family but operates under different electrical parameters (2.7V ~ 3.6V supply, 500 µA current draw) and supports dot matrix display configurations rather than segment-based displays. This device is classified as a substitute within the onsemi LCD driver portfolio but requires careful electrical parameter verification before implementation.

Parameter Comparison

Engineering Selection Recommendations

Both the LC75808W-E and LC75812PTH-8565-H are classified as obsolete products. Selection between these devices must be based on the specific display configuration requirements of the target application:

LC75808W-E Selection Criteria:

• Applications requiring 480, 540, or 600 segment LCD display support
• Systems operating within 4.5V to 6V supply voltage range
• Designs with power budget constraints (250 µA supply current)
• Existing PCB layouts utilizing 100-SQFP package footprint

LC75812PTH-8565-H Selection Criteria:

• Applications requiring dot matrix LCD display support (16 characters, 240 characters, 12 digits, or 13 digits)
• Systems operating within 2.7V to 3.6V supply voltage range
• Designs tolerating higher supply current (500 µA)
• PCB layouts compatible with 100-TQFP package footprint

Both devices maintain identical operating temperature ranges, moisture sensitivity levels, and regulatory compliance status. The choice between these alternatives is determined by display type compatibility and electrical operating parameters rather than environmental or compliance factors.

Frequently Asked Questions (FAQ)

Q: Can the LC75812PTH-8565-H directly replace the LC75808W-E in an existing design?

A: Direct replacement is not recommended without design modification. The LC75812PTH-8565-H operates at different supply voltage (2.7V ~ 3.6V versus 4.5V ~ 6V) and supports dot matrix display configurations rather than segment-based displays. PCB layout changes are required due to package differences (100-TQFP versus 100-SQFP).

Q: What are the key electrical differences between these LCD drivers?

A: The primary differences are supply voltage range, supply current draw, and display configuration support. The LC75808W-E requires higher supply voltage (4.5V ~ 6V) with lower current consumption (250 µA) and supports segment-based displays. The LC75812PTH-8565-H operates at lower voltage (2.7V ~ 3.6V) with higher current draw (500 µA) and supports dot matrix display configurations.

Q: Are both devices suitable for new designs?

A: Both devices are classified as obsolete. For new designs, consultation with onsemi regarding current-generation LCD driver alternatives is recommended. For legacy system support or device replacement, these obsolete parts remain available through authorized distributors.

Q: What package considerations apply to substitution?

A: The LC75808W-E uses a 100-SQFP (14x14) package, while the LC75812PTH-8565-H uses a 100-TQFP (14x14) package. Although both are 100-pin packages with identical physical dimensions, the pin assignments differ. PCB layout and footprint modifications are required for substitution.

Q: Do both devices share the same regulatory compliance status?

A: Yes. Both devices are REACH Unaffected, classified as EAR99 for export control purposes, and carry identical HTSUS commodity codes (8542.39.0001). Both maintain MSL 3 moisture sensitivity levels with 168-hour rating.
