ADSP-H3Y3 Equivalent & Substitute Parts

Part Overview

The ADSP-H3Y3 is a single-character yellow 7-segment LED display module manufactured by Broadcom Limited, packaged in a 10-DIP configuration. This component is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production support. The display operates at 2V forward voltage with a 20mA test current and features a 0.52" digit height with common cathode configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ADSP-H3Y3 is determined by the following critical parameters:

• Package Compatibility: 10-DIP (0.200", 5.08mm) form factor for direct PCB mounting
• Electrical Configuration: Common cathode architecture for signal compatibility
• Display Type: 7-segment LED for alphanumeric display capability
• Color: Yellow wavelength range (585–592nm)
• Electrical Operating Range: Forward voltage 2.0–2.1V and test current 10–20mA

The LDS-C323RI from Lumex Opto/Components Inc. meets these substitution criteria. While it features a smaller digit height (0.36" vs. 0.52"), it maintains identical package geometry, electrical configuration, and color specification. The forward voltage (2.1V) and test current (10mA) fall within acceptable operating parameters for common cathode 7-segment displays in this package class.

Parameter Comparison

Engineering Selection Recommendations

The LDS-C323RI is an active product with ROHS3 compliance and REACH unaffected status, providing long-term supply chain stability compared to the obsolete ADSP-H3Y3. Both components share identical package geometry and electrical configuration, enabling direct PCB layout compatibility.

Selection between these parts depends on application-specific visibility requirements. The ADSP-H3Y3 provides higher brightness (8mcd) and larger digit height (0.52"), while the LDS-C323RI operates at lower test current (10mA vs. 20mA) and maintains active manufacturing status. The forward voltage differential (2.1V vs. 2V) and wavelength variation (585nm vs. 592nm) remain within standard yellow LED display tolerances for most applications.

Frequently Asked Questions (FAQ)

Q: Can the LDS-C323RI replace the ADSP-H3Y3 in existing designs?

A: Yes, for PCB layout purposes. Both components use identical 10-DIP (0.200", 5.08mm) packaging and common cathode configuration. However, the smaller digit height (0.36" vs. 0.52") may affect visual display requirements. Electrical parameters (forward voltage 2.1V, test current 10mA) are compatible with standard 7-segment display driver circuits designed for the original part.

Q: What is the primary difference between these two parts?

A: The main differences are product status (obsolete vs. active), digit height (0.52" vs. 0.36"), brightness rating (8mcd vs. 2.25mcd), and test current (20mA vs. 10mA). Package, configuration, and color remain identical.

Q: Are there compliance or supply chain advantages to using the LDS-C323RI?

A: Yes. The LDS-C323RI is an active product with ROHS3 compliance and REACH unaffected status, ensuring ongoing availability and regulatory alignment. The ADSP-H3Y3 is obsolete and subject to supply discontinuation.

Q: How do wavelength differences affect display appearance?

A: The wavelength difference (592nm vs. 585nm) represents a minor shift within the yellow spectrum. Both parts produce yellow light suitable for standard alphanumeric display applications. Visual perception differences are negligible in most end-use environments.

Q: What are the power consumption implications of substitution?

A: The LDS-C323RI operates at lower test current (10mA vs. 20mA) but has higher maximum power dissipation (105mW vs. 52mW). Actual power consumption depends on circuit design and duty cycle. For applications requiring minimal power draw, the LDS-C323RI's lower test current provides an advantage.
