LTS-6780JD 7-Segment LED Display Equivalent & Substitute Parts

Part Overview

The LTS-6780JD is a single-character 7-segment LED display module manufactured by Lite-On Inc. This red LED display operates at 2.1V forward voltage with a 20mA test current and features a 0.56" digit height in a 10-DIP package configuration. The component is classified as Active product status and maintains ROHS3 compliance with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain considerations, or when equivalent electrical and mechanical specifications are required for system compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LTS-6780JD is determined by the following critical parameters:

Primary Compatibility Criteria:

• Display type: 7-Segment LED (single character)
• Common pin configuration: Common Cathode
• Package: 10-DIP (0.600", 15.24mm)
• Color: Red spectrum (wavelength 645nm–650nm)
• Digit height: 0.56" (14.22mm) or equivalent

Electrical Operating Parameters:

• Forward voltage (Vf): 1.85V–2.1V range
• Test current: 10mA–20mA range
• Millicandela rating: 0.32mcd–110mcd range

Compliance Requirements:

• RoHS3 compliance mandatory
• MSL 1 (Unlimited) moisture sensitivity

The three identified substitute parts (SC52-11SURKWA, SC56-11SURKWA, SC56-21SURKWA) from Kingbright maintain mechanical compatibility through identical 10-DIP packaging and common cathode configuration. All substitutes operate within acceptable electrical parameter ranges and meet RoHS3 compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

SC56-11SURKWA and SC56-21SURKWA (Kingbright): These parts provide the closest mechanical and electrical alignment with the LTS-6780JD. Both maintain identical digit height (0.56"), matching physical dimensions (0.750" H x 0.500" W), and equivalent test current (20mA). Forward voltage differential (1.95V vs. 2.1V) falls within acceptable operating margins for common cathode 7-segment applications. Both parts carry ROHS3 compliance and MSL 1 rating. SC56-11SURKWA and SC56-21SURKWA are functionally interchangeable for direct PCB replacement.

SC52-11SURKWA (Kingbright): This part operates at reduced digit height (0.52" vs. 0.56") and lower test current (10mA vs. 20mA). Physical dimensions differ in height (0.689" vs. 0.750") and depth (0.276" vs. 0.315"). SC52-11SURKWA is suitable only when display size reduction is acceptable and circuit design accommodates 10mA operation. ROHS3 compliance and MSL 1 rating are maintained.

All three substitutes meet mandatory compliance requirements and maintain 10-DIP package compatibility for socket-level replacement.

Frequently Asked Questions (FAQ)

Q: Can SC52-11SURKWA replace LTS-6780JD in existing designs? A: SC52-11SURKWA differs in digit height (0.52" vs. 0.56") and test current (10mA vs. 20mA). Mechanical fit requires verification due to dimensional differences. Electrical circuit redesign may be necessary to accommodate lower current operation. Use only when design specifications permit reduced display size and current.

Q: Are SC56-11SURKWA and SC56-21SURKWA interchangeable with LTS-6780JD? A: Both SC56-11SURKWA and SC56-21SURKWA maintain identical digit height, matching test current (20mA), and equivalent physical dimensions. Forward voltage operates within acceptable range (1.95V vs. 2.1V). Both are direct substitutes for socket-level replacement without circuit modification.

Q: What is the significance of the wavelength difference (650nm vs. 645nm)? A: Both wavelengths fall within the red spectrum and are visually indistinguishable in typical applications. The 5nm difference reflects manufacturing variation between Lite-On and Kingbright processes and does not affect functional compatibility.

Q: Do all substitute parts maintain the same package footprint? A: All substitute parts use 10-DIP (0.600", 15.24mm) packaging, ensuring identical PCB footprint and pin spacing. Physical height and depth dimensions vary slightly; verify clearance in confined mounting spaces.

Q: Are there compliance or certification differences between the main part and substitutes? A: All parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating. No compliance gaps exist between LTS-6780JD and the three identified substitutes.

Q: What is the brightness difference between LTS-6780JD and substitute parts? A: LTS-6780JD operates at 0.32mcd. SC52-11SURKWA delivers 110mcd, and both SC56-11SURKWA and SC56-21SURKWA deliver 97mcd. Substitute parts provide significantly higher brightness output. Circuit current-limiting resistors may require adjustment to maintain consistent display brightness.
