LTD-482GC Equivalent & Substitute Parts

Part Overview

The LTD-482GC is a 7-segment LED display module manufactured by Lite-On Inc., featuring a dual-character green display in a 16-DIP package. This component is classified as Active product status and is fully RoHS3 compliant. The display operates at 2.1V forward voltage with a 20mA test current and provides a 0.40" digit size suitable for numeric and alphanumeric applications requiring green LED indication.

Substitute parts are identified when equivalent functional performance can be achieved within the allowed electrical and mechanical parameters of the 7-segment display category, specifically matching the common anode configuration, green color, dual-character format, and 16-DIP package type.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LTD-482GC is determined by strict alignment with the following core parameters:

• Display Type: 7-Segment configuration
• Number of Characters: Dual-character (2) format
• Common Pin Configuration: Common Anode
• Color: Green (565nm wavelength peak)
• Digit/Alpha Size: 0.40" (10.16mm)
• Package / Case: 16-DIP
• RoHS Compliance: ROHS3 Compliant

The LDD-A402NI qualifies as a substitute part because it matches all mandatory substitution criteria. Variations in forward voltage (2.1V vs. 2.2V), test current (20mA vs. 10mA), millicandela rating (1.3mcd vs. 3.9mcd), and physical dimensions within tolerance ranges do not disqualify substitution when the core functional parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the LTD-482GC and LDD-A402NI are Active product status components with full RoHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity ratings, indicating equivalent reliability and regulatory standing for industrial and commercial applications.

The LDD-A402NI substitute provides higher brightness output (3.9mcd vs. 1.3mcd) while maintaining identical display configuration, package type, and compliance certifications. The forward voltage differential of 0.1V (2.2V vs. 2.1V) and lower test current specification (10mA vs. 20mA) are within acceptable operational ranges for common anode 7-segment display circuits.

Selection between these parts should be based on circuit design requirements, brightness visibility needs, and component availability. Both parts are suitable for direct substitution in 16-DIP socket applications requiring dual-character green 7-segment display functionality.

Frequently Asked Questions (FAQ)

Q: Can the LDD-A402NI replace the LTD-482GC in existing circuit designs?

A: Yes. Both parts share identical display type, character count, common anode configuration, color, digit size, package type, and compliance certifications. The forward voltage and current specifications are within acceptable operational ranges for standard 7-segment display driver circuits.

Q: What is the significance of the millicandela rating difference?

A: The LDD-A402NI provides 3.9mcd brightness compared to the LTD-482GC at 1.3mcd. This means the substitute part produces approximately three times higher light output. Applications requiring specific brightness levels should account for this difference in circuit design.

Q: Are there package compatibility concerns?

A: Both parts use 16-DIP package configuration with identical pin spacing (0.500", 12.70mm). They are mechanically and electrically compatible for direct socket substitution.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the LTD-482GC and LDD-A402NI are RoHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity ratings. Both maintain Active product status from their respective manufacturers.

Q: What is the impact of the 0.1V forward voltage difference?

A: The forward voltage variance between 2.1V and 2.2V is negligible for most circuit applications. Standard 7-segment display driver circuits accommodate this range without design modification.
