LTC-4724JG Equivalent & Substitute Parts

Part Overview

The LTC-4724JG is a 3-character green 7-segment LED display module manufactured by Lite-On Inc., designed for numeric and alphanumeric display applications. This component features a common cathode configuration with a 0.39" character height and operates at 2.05V forward voltage with 20mA test current. The part is currently active in production and RoHS3 compliant, making it suitable for modern electronic applications requiring standardized display functionality.

Substitute parts are identified when equivalent electrical and mechanical parameters allow direct replacement without circuit modification, maintaining the same pinout, package type, and functional performance within specified tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LTC-4724JG is determined by strict alignment of the following critical parameters:

• Package Type: 15-DIP (0.400", 10.16mm), 12 Leads — ensures mechanical and electrical compatibility with existing PCB layouts
• Display Configuration: 3-character, 7-segment, common cathode — maintains circuit interface compatibility
• Color: Green — preserves visual output specifications
• Physical Dimensions: 0.504" H x 1.182" W x 0.276" D — confirms form factor compatibility
• Electrical Ratings: Forward voltage (Vf), test current (20mA), and power dissipation — must remain within acceptable operating ranges for the application circuit

The HDSP-433G meets these substitution criteria with compatible electrical and mechanical parameters, allowing it to function as a direct replacement in applications designed for the LTC-4724JG.

Parameter Comparison

Engineering Selection Recommendations

Both the LTC-4724JG and HDSP-433G are active production components with ROHS3 compliance and MSL Level 1 rating, indicating equivalent environmental and regulatory suitability for modern applications. The HDSP-433G offers higher luminous intensity (5mcd versus 0.464mcd) and slightly lower power dissipation (65mW versus 70mW), with a marginally higher forward voltage (2.25V versus 2.05V). These differences remain within acceptable operating tolerances for standard display applications and do not preclude substitution in circuits designed for the LTC-4724JG.

Selection between these parts should be based on availability, lead time, and application-specific brightness requirements. Both components maintain identical package geometry, pinout, and functional interface, ensuring direct replacement capability.

Frequently Asked Questions (FAQ)

Q: Can the HDSP-433G replace the LTC-4724JG in an existing circuit?

A: Yes. Both components share identical package type (15-DIP), pinout (12 leads), physical dimensions, display configuration (3-character, 7-segment, common cathode), and electrical test current (20mA). The forward voltage difference (2.25V versus 2.05V) and wavelength variation (568nm versus 571nm) remain within acceptable tolerances for standard display applications.

Q: What are the key differences between these parts?

A: The HDSP-433G provides higher luminous intensity (5mcd versus 0.464mcd), lower maximum power dissipation (65mW versus 70mW), and a slightly higher typical forward voltage (2.25V versus 2.05V). The peak wavelength differs by 3nm within the green spectrum range.

Q: Are both parts RoHS compliant?

A: Yes. Both the LTC-4724JG and HDSP-433G are ROHS3 compliant with MSL Level 1 rating, suitable for applications requiring environmental and regulatory compliance.

Q: Does the brightness difference affect substitution compatibility?

A: The higher brightness of the HDSP-433G (5mcd versus 0.464mcd) represents improved luminous output. Applications designed for the LTC-4724JG will function with the HDSP-433G; however, circuit designers should evaluate whether increased brightness aligns with application requirements.

Q: Are the physical dimensions identical?

A: Yes. Both components measure 0.504" H x 1.182" W x 0.276" D (12.80mm x 30.02mm x 7.00mm), ensuring identical form factor and PCB mounting compatibility.
