LTS-6980HR 7-Segment LED Display - Equivalent & Substitute Parts

Part Overview

The LTS-6980HR is a 0.56" single-character red 7-segment LED display module manufactured by Lite-On Inc. in a 10-DIP package configuration. This component is classified as an active product and is commonly used in numeric display applications requiring compact form factor and standard logic-level interfacing. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and packaging specifications are maintained across alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LTS-6980HR is determined by strict equivalence across the following critical parameters:

• Display type (7-Segment)
• Character configuration (single character)
• Digit size (0.56")
• Color (Red)
• Common pin type (Common Cathode)
• Package format (10-DIP, 0.600" pitch)
• Electrical specifications (2V forward voltage, 20mA test current, 75mW maximum power dissipation)

The SC56-21EWA from Kingbright meets all substitution criteria. Dimensional variations within manufacturing tolerance (width 0.496" vs 0.500") do not preclude functional equivalence in standard PCB mounting applications.

Parameter Comparison

Engineering Selection Recommendations

Both the LTS-6980HR and SC56-21EWA maintain active product status and full compliance with ROHS3 standards. Selection between these parts should be based on:

• Availability and lead time requirements
• Supply chain continuity with preferred manufacturer
• Inventory levels at distribution partners
• Application-specific brightness requirements (LTS-6980HR: 2.4mcd; SC56-21EWA: 6.4mcd)
• Wavelength specifications (LTS-6980HR: 635nm; SC56-21EWA: 627nm)

Both components are suitable for direct substitution in standard 7-segment display applications with 10-DIP socket compatibility.

Frequently Asked Questions (FAQ)

Q: Can SC56-21EWA replace LTS-6980HR in existing designs? A: Yes. Both parts share identical electrical specifications (2V forward voltage, 20mA test current), common cathode configuration, 10-DIP package format, and maximum power dissipation rating. PCB footprints and pin assignments are compatible.

Q: What is the significance of the millicandela rating difference? A: The SC56-21EWA (6.4mcd) provides higher brightness than the LTS-6980HR (2.4mcd). This difference reflects manufacturing variations between suppliers but does not affect functional compatibility. Applications requiring specific brightness levels should account for this parameter during design validation.

Q: Are there dimensional compatibility concerns? A: Width dimensions differ slightly (0.496" vs 0.500"), but both parts conform to standard 10-DIP package specifications with 0.600" lead pitch. This variation is within typical manufacturing tolerance and does not impact PCB mounting or socket compatibility.

Q: What compliance certifications apply to both parts? A: Both the LTS-6980HR and SC56-21EWA are ROHS3 compliant, classified under ECCN EAR99, and carry HTSUS code 8541.41.0000. Moisture sensitivity level is 1 (Unlimited) for both components.

Q: How do wavelength specifications affect substitution? A: The LTS-6980HR operates at 635nm peak wavelength, while the SC56-21EWA operates at 627nm. Both are within the red spectrum range. Applications with strict color matching requirements should evaluate this parameter, though both parts are functionally equivalent for standard numeric display applications.
