LTS-5003AWC 7-Segment LED Display Equivalent & Substitute Parts

Part Overview

The LTS-5003AWC is a single-character red 7-segment LED display module manufactured by Lite-On Inc., packaged in a 10-DIP configuration. This active product operates at 1.7V forward voltage with 5mA test current, delivering 3.75mcd brightness at 660nm wavelength. The display features common cathode configuration with dimensions of 0.673" H × 0.488" W × 0.315" D (17.10mm × 12.40mm × 8.00mm).

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative manufacturers offer improved lead times, or when design requirements allow for compatible alternatives that meet the same functional and electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and ROHS3 compliance, ensuring continued availability and regulatory alignment with the LTS-5003AWC.

HDSP-5503 operates at elevated forward voltage (2.1V) and test current (20mA), resulting in higher power dissipation (105mW). This part is suitable for applications where increased brightness (2.8mcd) is acceptable and power budget permits higher consumption.

HDSP-5553 matches the LTS-5003AWC forward voltage (1.7V) and test current (5mA) specifications. Reduced brightness (1.48mcd) and lower power dissipation (52mW) make this part suitable for low-power applications where brightness requirements are less stringent.

HDSP-H103 operates at identical forward voltage (1.7V) and test current (5mA) with the lowest power dissipation (37mW) among all substitutes. Brightness rating (4.2mcd) exceeds the LTS-5003AWC, making this part suitable for applications requiring enhanced visibility within minimal power constraints.

HDSP-H153 operates at slightly elevated forward voltage (1.8V) and test current (20mA), delivering the highest brightness (16mcd) among all listed parts. Maximum power dissipation (96mW) accommodates high-brightness applications where visibility is critical.

Frequently Asked Questions (FAQ)

Q: Can HDSP-5503 be used as a direct replacement for LTS-5003AWC?

A: HDSP-5503 is mechanically and functionally compatible but operates at higher forward voltage (2.1V vs. 1.7V) and test current (20mA vs. 5mA). Circuit design must accommodate increased power dissipation (105mW vs. 75mW). Direct pin-for-pin substitution is possible; however, current-limiting resistor values require recalculation.

Q: What is the brightness difference between LTS-5003AWC and HDSP-H153?

A: LTS-5003AWC delivers 3.75mcd at 660nm wavelength. HDSP-H153 delivers 16mcd at 645nm wavelength. The HDSP-H153 provides significantly higher brightness output, suitable for applications requiring enhanced visibility. Wavelength difference (660nm vs. 645nm) results in slightly different perceived color tone.

Q: Are all substitute parts available in the same packaging?

A: All substitute parts are packaged in 10-DIP (0.600", 15.24mm) configuration, identical to the LTS-5003AWC. Physical dimensions vary slightly (LTS-5003AWC: 17.10mm × 12.40mm × 8.00mm; Broadcom parts: 17.02mm × 12.57mm × 8.00mm), remaining within acceptable PCB layout tolerances.

Q: Which substitute part has the lowest power consumption?

A: HDSP-H103 has the lowest maximum power dissipation at 37mW, operating at 1.7V forward voltage and 5mA test current. This part is optimal for battery-powered or low-power applications.

Q: Do all substitute parts meet RoHS3 compliance?

A: All substitute parts listed are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the LTS-5003AWC environmental and regulatory specifications.

Q: Can wavelength differences affect circuit performance?

A: Wavelength differences (660nm, 645nm, 635nm) represent variations in perceived color tone within the red spectrum. Circuit performance remains unaffected. Visual appearance may differ slightly; applications requiring specific color matching should account for wavelength specifications.
