LTS-6680E 7-Segment LED Display - Equivalent & Substitute Parts

Part Overview

The LTS-6680E is a 0.56" single-character 7-segment LED display manufactured by Lite-On Inc. in a 10-DIP package configuration. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The display operates at 2V forward voltage with 20mA test current and features orange-red color output at 630nm peak wavelength.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the LTS-6680E is determined by strict alignment of the following electrical and mechanical parameters:

• Display Configuration: 7-segment, single character, common cathode topology
• Package Compatibility: 10-DIP (0.600", 15.24mm) form factor
• Electrical Specifications: 2V forward voltage, 20mA test current, 75mW maximum power dissipation
• Physical Envelope: 0.750" H x 0.496" W minimum width tolerance, 0.315" D depth
• Color Output: Orange-red or red wavelength (630nm–635nm range)

Two substitute parts meet these criteria: LTS-6980HR (Lite-On Inc., direct manufacturer alternative) and SC56-11EWA (Kingbright, cross-manufacturer equivalent).

Parameter Comparison

Engineering Selection Recommendations

LTS-6980HR is the direct manufacturer alternative from Lite-On Inc. and maintains identical electrical and mechanical specifications to the LTS-6680E. This part is currently in active production status with RoHS3 compliance and REACH affected designation. Inventory availability is confirmed at 669 pieces. Selection of this substitute provides continuity within the same manufacturer ecosystem.

SC56-11EWA is a cross-manufacturer equivalent from Kingbright that satisfies all core substitution parameters. This part is active production status with RoHS3 compliance and REACH unaffected designation. The physical width dimension is 0.500" compared to 0.496" for the main part, representing a 0.004" (0.1mm) increase within typical PCB layout tolerance. The millicandela rating is 6.4mcd versus 2.4mcd, indicating higher luminous intensity. Inventory availability is confirmed at 6496 pieces. This substitute is suitable for applications where increased brightness is acceptable or beneficial.

Both substitutes operate within the same electrical envelope (2V, 20mA, 75mW) and maintain 10-DIP package compatibility. Color output shifts from orange-red (630nm) to red wavelength (627nm–635nm), which may affect visual appearance in applications requiring specific color matching.

Frequently Asked Questions (FAQ)

Q: Can LTS-6980HR be used as a direct replacement for LTS-6680E?

A: Yes. LTS-6980HR maintains identical electrical specifications (2V, 20mA, 75mW), common cathode configuration, 0.56" digit size, and 10-DIP package form factor. The primary difference is color output: LTS-6980HR produces red at 635nm versus orange-red at 630nm for the LTS-6680E. Both parts have MSL 1 rating and identical power dissipation limits.

Q: What is the difference between SC56-11EWA and the Lite-On alternatives?

A: SC56-11EWA is manufactured by Kingbright and meets all core electrical and package requirements. Key differences include: (1) physical width of 0.500" versus 0.496", a 0.004" variance; (2) millicandela rating of 6.4mcd versus 2.4mcd, providing higher brightness; (3) peak wavelength of 627nm versus 630nm or 635nm. The part is RoHS3 compliant and REACH unaffected.

Q: Are there pin-to-pin compatibility concerns between these substitutes?

A: All three parts use 10-DIP (0.600", 15.24mm) package configuration with common cathode topology. Pin assignments are identical for 7-segment display function. No circuit redesign is required for electrical substitution.

Q: Does the 0.004" width difference between LTS-6680E and SC56-11EWA affect PCB layout?

A: The width difference (0.496" versus 0.500") is 0.1mm and falls within standard PCB design tolerances for DIP component placement. No layout modification is necessary for mechanical fit.

Q: What compliance certifications apply to each substitute?

A: LTS-6980HR carries RoHS3 compliance and REACH affected status. SC56-11EWA carries RoHS3 compliance and REACH unaffected status. Both parts have MSL 1 (unlimited moisture sensitivity) rating. All three parts share EAR99 ECCN and 8541.41.0000 HTSUS classification.

Q: Which substitute should be selected for new designs?

A: Selection depends on application requirements. For color-critical applications requiring orange-red output, LTS-6980HR maintains closest spectral match. For applications where increased brightness is beneficial, SC56-11EWA provides 6.4mcd output. Both are active production parts with confirmed inventory availability.
