ADSP-H5Y3 Equivalent & Substitute Parts

Part Overview

The ADSP-H5Y3 is a single-character 7-segment LED display module manufactured by Broadcom Limited. This yellow display operates at 2V forward voltage with a 20mA test current and features a 0.80" digit height in a 10-DIP package configuration. The product is currently obsolete, making identification of compatible substitute components essential for ongoing system support, maintenance, and new design implementations where this display type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADSP-H5Y3 is determined by the following critical parameters:

• Display Configuration: Single-character 7-segment format with common cathode architecture
• Electrical Characteristics: Forward voltage tolerance and test current compatibility
• Package Compatibility: 10-DIP (0.600", 15.24mm) footprint for direct PCB mounting
• Optical Properties: Yellow color emission within the specified wavelength range
• Physical Dimensions: Overall envelope and digit height must accommodate mechanical constraints

The LTS-547AKS from Lite-On Inc. qualifies as a substitute based on matching display type, common cathode configuration, package format, and electrical operating parameters within acceptable tolerances for this component category.

Parameter Comparison

Engineering Selection Recommendations

The LTS-547AKS serves as an active substitute for the obsolete ADSP-H5Y3. Both components share identical package footprints, common cathode architecture, and compatible electrical operating parameters. The LTS-547AKS maintains RoHS3 compliance and carries unlimited moisture sensitivity level (MSL 1) classification, matching the environmental specifications of the original component.

Selection of the LTS-547AKS is appropriate for applications where the 10-DIP common cathode 7-segment yellow display format is required and the component is currently unavailable. The forward voltage differential of 0.05V falls within typical design tolerances for LED display circuits. Designers must evaluate digit height differences (0.80" versus 0.52") and brightness characteristics (33mcd versus 1.4mcd) against specific application visual requirements and mechanical space constraints.

Frequently Asked Questions (FAQ)

Q: Can the LTS-547AKS directly replace the ADSP-H5Y3 without circuit modification?

A: Both components share the 10-DIP package footprint and common cathode configuration, enabling direct PCB mounting. The forward voltage difference of 0.05V (2V to 2.05V) is within standard LED circuit design tolerances and does not require circuit redesign for typical applications.

Q: What are the primary differences between these two displays?

A: The main differences are digit height (0.80" versus 0.52"), brightness rating (33mcd versus 1.4mcd), and power dissipation (52mW versus 70mW). The LTS-547AKS produces a smaller character with lower brightness output. Wavelength peak values differ slightly (592nm versus 588nm), both within the yellow spectrum.

Q: Is the LTS-547AKS suitable for applications requiring high brightness?

A: The LTS-547AKS has a significantly lower millicandela rating (1.4mcd) compared to the ADSP-H5Y3 (33mcd). Applications requiring high visibility or operation in bright ambient light conditions should evaluate whether this brightness reduction is acceptable for the intended use case.

Q: Are there any compliance or environmental differences?

A: The LTS-547AKS carries active product status with RoHS3 compliance certification. Both components share MSL 1 (Unlimited) moisture sensitivity classification and identical ECCN and HTSUS codes, indicating equivalent regulatory and environmental handling requirements.

Q: What package considerations apply to this substitution?

A: Both the ADSP-H5Y3 and LTS-547AKS use 10-DIP (0.600", 15.24mm) packaging. Physical envelope dimensions are nearly identical, with overall height and width matching within 0.002" to 0.004". Mechanical clearance and mounting considerations remain unchanged between the two components.
