Key Parameters

Substitute Part Grouping Explanation

The LC75832E-E qualifies as a substitute based on the following alignment of critical parameters:

Matching Parameters:

• Manufacturer: onsemi (same manufacturer ensures design continuity)
• Display Type: LCD (identical application category)
• Interface: Serial (compatible communication protocol)
• Mounting Type: Surface Mount (same assembly process)
• Package / Case: 64-BQFP (identical physical footprint and pin count)
• Moisture Sensitivity Level (MSL): 4 (72 Hours) (equivalent handling requirements)
• REACH Status: REACH Unaffected (equivalent regulatory compliance)

Enhanced Specifications: The LC75832E-E provides improved segment capacity (54/108 segments versus 53/104 segments), extended operating temperature range (-40°C ~ 105°C versus -40°C ~ 85°C), and active product status, making it suitable for applications requiring the LC75822ED-E functionality.

Parameter Comparison

Engineering Selection Recommendations

The LC75832E-E is the appropriate substitute for the obsolete LC75822ED-E. Both devices share identical packaging (64-BQFP), interface protocol (Serial), and regulatory compliance status (REACH Unaffected). The LC75832E-E maintains active product status with onsemi, ensuring long-term availability and supply chain stability. The increased segment capacity and extended temperature range of the LC75832E-E provide design flexibility for applications previously constrained by LC75822ED-E specifications. Both components meet equivalent moisture sensitivity requirements for standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the LC75832E-E directly replace the LC75822ED-E in existing designs?

A: Yes. Both devices use identical 64-BQFP packaging and serial interface protocol. Pin compatibility and functional equivalence are maintained across the substitution.

Q: What is the significance of the segment configuration difference (53/104 versus 54/108)?

A: The LC75832E-E supports additional segment capacity. Designs utilizing the LC75822ED-E at or below 53/104 segment operation will function identically with the LC75832E-E. The additional segments in the substitute part do not impact compatibility.

Q: Are there supply voltage compatibility concerns?

A: The LC75832E-E operates across 2.7V to 6V, while the LC75822ED-E operates across 3V to 6.5V. Applications operating at 3V to 6V fall within both ranges. Designs requiring operation below 3V or above 6V require circuit redesign and are outside the scope of direct substitution.

Q: Does the extended operating temperature range of the LC75832E-E affect compatibility?

A: No. The LC75832E-E temperature range (-40°C ~ 105°C) encompasses the LC75822ED-E range (-40°C ~ 85°C). Applications operating within the original temperature specification remain fully compatible.

Q: What is the moisture sensitivity implication for assembly?

A: Both components carry MSL 4 (72 Hours) rating, requiring identical handling, storage, and reflow procedures. No process changes are necessary during substitution.
