LTC-4724G Equivalent & Substitute Parts

Part Overview

The LTC-4724G is a 3-character green 7-segment LED display module manufactured by Lite-On Inc., designed for numeric and alphanumeric display applications. This common cathode display operates at 2.1V forward voltage with a 20mA test current and features a 0.39" character size in a 15-DIP package. The product is currently active and RoHS3 compliant, making it suitable for modern electronic applications requiring standardized display functionality.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design flexibility allows for functionally equivalent alternatives that meet application requirements.

Substitute Part Grouping Explanation

The HDSP-433G qualifies as a direct substitute for the LTC-4724G based on the following critical parameters:

• Display Configuration: Both parts feature 3-character, 7-segment, common cathode architecture
• Package Compatibility: Identical 15-DIP (0.400", 10.16mm) package with 12 leads
• Physical Dimensions: Matching form factor of 0.504" H x 1.182" W x 0.276" D
• Color and Wavelength: Both emit green light within the visible spectrum (565nm vs 568nm peak wavelength)
• Electrical Operating Point: Both operate at 20mA test current with forward voltages within acceptable tolerance (2.1V vs 2.25V)
• Compliance: Both are RoHS3 compliant and carry EAR99 ECCN classification

The substitution is valid because the electrical and mechanical parameters fall within the allowable range for this display module category, and the package pinout remains consistent.

Parameter Comparison

Engineering Selection Recommendations

Both the LTC-4724G and HDSP-433G are active products with full RoHS3 compliance and EAR99 classification, making them suitable for current production designs. The HDSP-433G offers higher brightness (5mcd vs 2.2mcd) and lower maximum power dissipation (65mW vs 75mW), while the LTC-4724G operates at a lower typical forward voltage (2.1V vs 2.25V). Selection between these parts should be based on application-specific brightness requirements and power budget constraints. Both parts maintain identical mechanical and electrical interface characteristics, ensuring direct substitution capability at the circuit board level.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical package geometry (15-DIP), pinout configuration (12 leads), and electrical operating parameters (20mA test current, common cathode architecture). The forward voltage difference (2.1V vs 2.25V) and brightness difference (2.2mcd vs 5mcd) are within acceptable tolerances for 7-segment display applications.

Q: What are the key differences between these two parts?

A: The primary differences are forward voltage (LTC-4724G: 2.1V typical; HDSP-433G: 2.25V typical), brightness rating (LTC-4724G: 2.2mcd; HDSP-433G: 5mcd), and maximum power dissipation (LTC-4724G: 75mW; HDSP-433G: 65mW). Both maintain identical character count, display type, common pin configuration, and physical dimensions.

Q: Are there any compliance or certification differences?

A: No. Both parts are RoHS3 compliant, carry EAR99 ECCN classification, and maintain MSL Level 1 (Unlimited) moisture sensitivity ratings.

Q: Does the package remain the same for both parts?

A: Yes. Both the LTC-4724G and HDSP-433G use the 15-DIP (0.400", 10.16mm) package with 12 leads and identical physical dimensions of 0.504" H x 1.182" W x 0.276" D.

Q: Which part should I select for brightness-critical applications?

A: The HDSP-433G provides higher brightness at 5mcd compared to the LTC-4724G at 2.2mcd. Selection should be based on the specific luminous intensity requirements of your application.
