LTS-4801E 7-Segment LED Display - Equivalent & Substitute Parts

Part Overview

The LTS-4801E is a single-character 7-segment LED display module manufactured by Lite-On Inc., designed for numeric and alphanumeric display applications. This common anode display operates at 2V forward voltage with a 20mA test current, featuring an orange-red color output at 630nm wavelength. The component is housed in a 10-DIP (0.300", 7.62mm) package and maintains active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts become necessary when addressing supply chain constraints, inventory availability, or when design specifications permit operation within the electrical and mechanical tolerances of alternative qualified components sharing the same package footprint and pin configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LTS-4801E is determined by strict adherence to the following mandatory parameters:

Required Matching Criteria:

• Display Type: 7-Segment, single character configuration
• Common Pin: Common Anode topology
• Package / Case: 10-DIP (0.300", 7.62mm) footprint
• Physical Dimensions: Compatible with 0.508" H x 0.382" W x 0.276" D envelope
• Digit/Alpha Size: 0.39" to 0.40" range (10.00mm to 10.16mm)

Allowable Parameter Variations:

• Voltage - Forward (Vf): 1.7V to 2V range (within common anode LED specifications)
• Current - Test: 5mA to 20mA range (design-dependent current limiting)
• Color: Red or Orange-Red (visible spectrum compatibility)
• Wavelength - Peak: 630nm to 645nm range (human-perceptible color consistency)
• Millicandela Rating: 2.2mcd to 3.9mcd (brightness variation acceptable with appropriate current limiting)
• Power Dissipation: 37mW to 75mW (thermal design margin dependent)

The substitute parts HDSP-F101 and HDSP-F111 meet all required matching criteria and fall within allowable parameter variations, qualifying them as direct electrical and mechanical equivalents.

Parameter Comparison

Engineering Selection Recommendations

All three components—LTS-4801E, HDSP-F101, and HDSP-F111—maintain active product status and ROHS3 compliance, confirming ongoing manufacturer support and regulatory alignment for new designs and production environments.

HDSP-F101 and HDSP-F111 are electrically and mechanically interchangeable with the LTS-4801E within the specified parameter tolerances. The primary distinction between the two Broadcom substitutes is packaging: HDSP-F101 is supplied in tube packaging, while HDSP-F111 is supplied in bulk packaging. Both share identical electrical specifications and physical dimensions.

Selection between the LTS-4801E and its Broadcom equivalents should be based on supply chain availability, inventory position, and packaging requirements for your production workflow. The lower forward voltage (1.7V vs. 2V) and reduced test current (5mA vs. 20mA) of the HDSP series result in lower power dissipation, which may provide thermal design benefits in current-limited applications.

Frequently Asked Questions (FAQ)

Q: Can HDSP-F101 and HDSP-F111 be used interchangeably with LTS-4801E in existing designs?

A: Yes. Both Broadcom parts share the same 10-DIP package footprint, common anode pin configuration, and compatible electrical operating ranges. No PCB redesign or circuit modification is required for direct substitution.

Q: What is the difference between HDSP-F101 and HDSP-F111?

A: The components are electrically and mechanically identical. The sole difference is packaging: HDSP-F101 is supplied in tube packaging, while HDSP-F111 is supplied in bulk packaging. Select based on your procurement and assembly requirements.

Q: Will the color difference between orange-red (LTS-4801E) and red (HDSP series) affect my application?

A: The wavelength difference (630nm vs. 645nm) represents a shift within the red spectrum. Visual perception of this difference depends on application context. If color matching is critical to your design specification, retain the LTS-4801E. If color variation is acceptable, the HDSP series substitutes are suitable.

Q: The HDSP parts operate at lower current (5mA vs. 20mA). Will brightness be affected?

A: The HDSP series has a higher millicandela rating (3.9mcd vs. 2.2mcd), compensating for the lower test current specification. Brightness in your application depends on your circuit's current-limiting design. Verify that your current-limiting resistor values produce acceptable brightness with the substitute part's electrical characteristics.

Q: Are all three parts suitable for new designs?

A: Yes. All three components maintain active product status and ROHS3 compliance. Selection should be based on supply availability, packaging preference, and any color or brightness requirements specific to your application.
