LTS-4610AE 7-Segment LED Display - Equivalent & Substitute Parts

Part Overview

The LTS-4610AE is a single-character 7-segment LED display module manufactured by Lite-On Inc. This common anode display operates at 2V forward voltage with a 20mA test current and features an orange-red color output at 630nm peak wavelength. The component is housed in a 14-DIP package with 0.40" character size and is classified as Active product status with ROHS3 compliance. Substitute parts are identified when equivalent electrical and mechanical parameters align with application requirements, enabling direct replacement in circuit designs without functional degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LTS-4610AE is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Display Type: 7-Segment (single character only)
• Common Pin Configuration: Common Anode
• Package / Case: 14-DIP (0.300", 7.62mm)
• Character Size: 0.40" (10.16mm)
• Voltage - Forward (Vf) Typical: 2V ±0.05V tolerance
• Current - Test: 20mA
• Physical Dimensions: Height 0.738", Width 0.386", Depth 0.200" ±0.01"

Allowable Variation Parameters:

• Color: Orange-Red, Red (within visible spectrum 627nm–635nm)
• Wavelength - Peak: 627nm–635nm range
• Millicandela Rating: 2.2mcd–5.6mcd (brightness variation acceptable)
• Power Dissipation (Max): 65mW–75mW (within thermal budget)

The identified substitute parts HDSP-311E and SA04-11EWA meet all critical matching parameters while operating within allowable variation ranges. Both maintain common anode configuration, 14-DIP package format, 0.40" character size, and compatible voltage/current specifications.

Parameter Comparison

Engineering Selection Recommendations

All three components—LTS-4610AE, HDSP-311E, and SA04-11EWA—maintain Active product status and ROHS3 compliance, confirming ongoing manufacturing support and regulatory alignment. Selection between these parts is based on the following engineering criteria:

LTS-4610AE (Primary Part): Orange-red color output at 630nm wavelength with 2.2mcd brightness. Packaged in Tube format. Recommended for applications requiring the specific orange-red spectral output.

HDSP-311E (Broadcom Substitute): Red color output at 635nm wavelength with 3.2mcd brightness. Forward voltage 2.05V (within 2.5% tolerance). Packaged in Bulk format. Suitable for applications where red color substitution is acceptable and higher brightness is beneficial. Package lead count noted as 10 Leads.

SA04-11EWA (Kingbright Substitute): Red color output at 627nm wavelength with 5.6mcd brightness. Forward voltage 2V (exact match). Packaged in Tube format. Suitable for applications requiring maximum brightness within the red spectrum and matching the original packaging format.

All three parts operate at identical 20mA test current and maintain compatible 14-DIP package footprints with 0.40" character size. Physical dimension variations (depth 0.200"–0.201") and package pitch differences (7.50mm–7.62mm) are within standard PCB layout tolerances for through-hole 14-DIP components.

Frequently Asked Questions (FAQ)

Q: Can HDSP-311E or SA04-11EWA be used as direct replacements for LTS-4610AE?

A: Yes, both parts are electrically and mechanically compatible substitutes. All three components share common anode configuration, 14-DIP package format, 0.40" character size, 2V nominal forward voltage, and 20mA test current. The primary difference is color output: LTS-4610AE produces orange-red (630nm), while HDSP-311E and SA04-11EWA produce red (635nm and 627nm respectively). Color substitution is acceptable in applications where spectral output is not a critical design parameter.

Q: What are the brightness differences between these parts?

A: LTS-4610AE provides 2.2mcd, HDSP-311E provides 3.2mcd, and SA04-11EWA provides 5.6mcd. Higher millicandela ratings indicate greater brightness. Selection depends on visibility requirements in the target application environment.

Q: Are there package compatibility concerns?

A: All three parts use 14-DIP package format suitable for standard through-hole PCB layouts. Minor variations exist: HDSP-311E specifies 10 Leads with 0.300" (7.62mm) pitch, SA04-11EWA specifies 0.295" (7.50mm) pitch, and LTS-4610AE specifies 0.300" (7.62mm) pitch. These variations are within standard PCB design tolerances for 14-DIP components and do not prevent interchangeability on existing PCB layouts.

Q: What is the voltage tolerance for substitution?

A: LTS-4610AE and SA04-11EWA both specify 2V forward voltage. HDSP-311E specifies 2.05V, representing a 2.5% increase. This variation is within acceptable operating range for common anode 7-segment display circuits and does not require circuit redesign.

Q: Do all parts meet the same compliance standards?

A: Yes. All three components are ROHS3 compliant and maintain Moisture Sensitivity Level 1 (Unlimited). HDSP-311E additionally specifies REACH Unaffected status. All parts carry ECCN EAR99 and HTSUS 8541.41.0000 classifications.

Q: Which part should be selected for new designs?

A: Selection is based on application-specific requirements. For orange-red spectral output, use LTS-4610AE. For red output with higher brightness, use SA04-11EWA (5.6mcd) or HDSP-311E (3.2mcd). All three parts are Active status with confirmed manufacturing availability.
