LTD-585G Equivalent & Substitute Parts

Part Overview

The LTD-585G is a dual-character 7-segment LED display module manufactured by Lite-On Inc. with a 0.50" digit size and green color output. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The display operates at 2.1V forward voltage with 20mA test current and is housed in an 18-DIP package.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the LTD-585G is based on the following critical parameters that must remain consistent:

• Display Configuration: 2-character, 7-segment, common anode architecture
• Electrical Specifications: 2.1V forward voltage, 20mA test current, 565nm peak wavelength (green)
• Package Type: 18-DIP (0.600", 15.24mm) form factor
• Optical Output: Green color with compatible millicandela rating
• Power Dissipation: Maximum 75mW per character pair

The primary substitute LTD-6410G maintains all critical electrical and mechanical parameters while offering an active product status and improved availability. The digit size increases from 0.50" to 0.56", representing a minor dimensional change that does not affect electrical compatibility or pinout configuration.

Parameter Comparison

Engineering Selection Recommendations

The LTD-6410G is the manufacturer-recommended substitute for the obsolete LTD-585G. Both components share identical electrical specifications, package footprint, and pinout configuration. The LTD-6410G offers the following advantages:

• Active Product Status: Currently manufactured and supported by Lite-On Inc., ensuring long-term availability and supply chain stability
• Regulatory Compliance: ROHS3 compliant and REACH affected, meeting current environmental and safety standards
• Enhanced Optical Performance: Millicandela rating of 2.4mcd compared to 2.2mcd provides improved brightness
• Dimensional Compatibility: The 18-DIP package remains unchanged; PCB layout and connector compatibility are maintained

The digit size increase from 0.50" to 0.56" requires verification of mechanical clearance within the end-use application enclosure. Electrical circuit design requires no modification.

Frequently Asked Questions (FAQ)

Q: Can the LTD-6410G be used as a direct replacement for the LTD-585G without circuit modifications?

A: Yes. Both components operate at identical electrical specifications (2.1V forward voltage, 20mA test current) with the same 18-DIP pinout. No circuit redesign is required.

Q: What is the primary difference between these two parts?

A: The LTD-6410G features a larger digit size (0.56" versus 0.50") and improved brightness (2.4mcd versus 2.2mcd). The LTD-585G is obsolete; the LTD-6410G is an active product with current manufacturing support.

Q: Will the larger digit size affect PCB layout?

A: The package footprint and pinout remain identical. Physical clearance within the product enclosure must be evaluated, as the display face is approximately 0.06" larger in height and width.

Q: Are there compliance differences between these parts?

A: The LTD-6410G is ROHS3 compliant and REACH affected. Compliance status for the obsolete LTD-585G is not specified in available documentation.

Q: What is the packaging difference?

A: The LTD-585G packaging is not specified. The LTD-6410G is supplied in tube packaging, which is standard for active production components.
