LTS-4301G 7-Segment LED Display - Equivalent & Substitute Parts

Part Overview

The LTS-4301G is a single-character 7-segment LED display module manufactured by Lite-On Inc. This green LED display operates at 2.1V forward voltage with a 20mA test current and features a common cathode configuration. The device is housed in a 10-DIP package measuring 0.508" H x 0.382" W x 0.276" D. The LTS-4301G maintains active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required for design flexibility or supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LTS-4301G are identified based on the following electrical and mechanical compatibility criteria:

Primary Compatibility Parameters:

• Display Type: 7-Segment single character
• Package / Case: 10-DIP (0.300", 7.62mm)
• Color: Green
• Voltage - Forward (Vf): 2.1V
• Common Pin Configuration: Common Cathode

The LTS-4301G operates with a common cathode configuration. HDSP-F503 is a direct substitute as it maintains the same common cathode topology, 10-DIP package, green color, and 2.1V forward voltage specification. HDSP-F501 is listed as an alternative but operates with a common anode configuration, which represents a different electrical interface requiring circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

HDSP-F503 (Broadcom Limited) is the primary substitute for the LTS-4301G. Both devices share identical common cathode configuration, 10-DIP package footprint, green color, and 2.1V forward voltage. All three parts maintain active product status and ROHS3 compliance. The HDSP-F503 is available in tube packaging and maintains MSL 1 rating.

HDSP-F501 (Broadcom Limited) operates with common anode configuration, which differs fundamentally from the LTS-4301G common cathode topology. This part requires circuit interface modification and is not a direct pin-compatible substitute.

All substitute candidates are manufactured by established suppliers with active product status and full regulatory compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can HDSP-F501 be used as a direct replacement for LTS-4301G?

A: No. HDSP-F501 uses common anode configuration while LTS-4301G uses common cathode. These represent different electrical interfaces and require different circuit connections. Pin compatibility does not exist.

Q: Is HDSP-F503 a pin-compatible substitute for LTS-4301G?

A: Yes. HDSP-F503 maintains the same 10-DIP package footprint, common cathode configuration, green color, and 2.1V forward voltage as LTS-4301G. Both devices are electrically and mechanically compatible.

Q: What are the key differences between LTS-4301G and HDSP-F503?

A: The primary differences are digit size (0.39" vs 0.40"), test current (20mA vs 10mA), brightness rating (2.2mcd vs 3.5mcd), and physical depth (0.276" vs 0.250"). Forward voltage and package type are identical.

Q: Are all three parts RoHS compliant?

A: Yes. LTS-4301G, HDSP-F501, and HDSP-F503 are all ROHS3 compliant with MSL 1 rating.

Q: What packaging options are available?

A: LTS-4301G is supplied in tube packaging. HDSP-F501 is supplied in bulk packaging. HDSP-F503 is supplied in tube packaging.
