LTS-4801G Equivalent & Substitute Parts

Part Overview

The LTS-4801G is a 7-segment LED display module manufactured by Lite-On Inc., designed for single-digit numeric and character display applications. This green LED display operates as a common anode configuration with a 0.40" digit height and is packaged in a 10-DIP format. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified to provide design flexibility, inventory alternatives, and continuity of supply for applications requiring equivalent display functionality and electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

All three parts—LTS-4801G, HDSP-F511, and LA-401MD—maintain active product status with full RoHS3 compliance and MSL 1 rating. Selection between these parts should be based on inventory availability, lead time requirements, and established supply chain relationships. The HDSP-F511 (Broadcom Limited) and LA-401MD (Rohm Semiconductor) are manufacturer-recommended substitutes that satisfy all electrical and mechanical compatibility requirements for the LTS-4801G application.

Frequently Asked Questions (FAQ)

Q: Can HDSP-F511 or LA-401MD be used as direct replacements for LTS-4801G?

A: Yes. Both parts meet the core substitution criteria: identical 7-segment display type, single-character configuration, 0.40" digit height, common anode pin configuration, green color, and 10-DIP package format. All three parts operate at 2.1V forward voltage and 10mA test current with equivalent RoHS3 compliance and MSL 1 ratings.

Q: Are there physical dimension differences between these parts?

A: Minor dimensional variations exist. The LTS-4801G dimensions are not specified in the provided data. The HDSP-F511 measures 0.508" H x 0.385" W x 0.250" D (12.90mm x 9.79mm x 6.36mm), while the LA-401MD measures 0.512" H x 0.378" W x 0.276" D (13.00mm x 9.60mm x 7.00mm). These variations are within typical tolerance ranges for 10-DIP packaged displays and should not affect PCB layout compatibility.

Q: What are the brightness differences between substitute parts?

A: The HDSP-F511 has a millicandela rating of 3.5mcd at 566nm wavelength, while the LA-401MD has a millicandela rating of 16mcd at 563nm wavelength. Both operate within the green spectrum. Application brightness requirements should determine the appropriate selection.

Q: Do all parts have the same power dissipation?

A: No. The HDSP-F511 has a maximum power dissipation of 105mW, while the LA-401MD has a maximum power dissipation of 60mW. The LTS-4801G power dissipation is not specified in the provided data. Thermal design considerations should account for these differences in high-volume or continuous-operation applications.

Q: Are all parts RoHS3 compliant?

A: Yes. LTS-4801G, HDSP-F511, and LA-401MD are all ROHS3 compliant with MSL 1 (unlimited moisture sensitivity) ratings, meeting current environmental and regulatory requirements.
