HDSP-H1G3 Equivalent & Substitute Parts

Part Overview

The HDSP-H1G3 is a single-character 7-segment LED display module manufactured by Broadcom Limited. It features a 1-inch green display with common cathode configuration, designed for numeric and alphanumeric applications. The part operates at 2V forward voltage with a 20mA test current and delivers 25mcd brightness output.

This component is classified as obsolete. Identifying suitable substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this display module.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HDSP-H1G3 is determined by the following critical parameters:

• Display Type: 7-Segment configuration
• Number of Characters: Single character
• Character Size: 1.00" (25.40mm)
• Color: Green
• Common Pin Configuration: Common Cathode
• Package Type: 10-DIP (1.200", 30.48mm)
• Physical Dimensions: 1.339" H x 0.945" W x 0.413" D

The LDS-CA12RI from Lumex Opto/Components Inc. satisfies all primary substitution criteria. Both parts share identical display type, character count, size, color, common cathode configuration, package format, and physical envelope. Electrical parameters (forward voltage, test current, brightness, and wavelength) differ within acceptable ranges for typical LED display applications, and both parts maintain equivalent power dissipation characteristics.

Parameter Comparison

Engineering Selection Recommendations

The HDSP-H1G3 is classified as obsolete, making the LDS-CA12RI a viable substitute for ongoing applications. Both parts maintain ROHS3 compliance and equivalent regulatory status (REACH Unaffected, ECCN EAR99, HTSUS 8541.41.0000).

The LDS-CA12RI is currently in active production status, ensuring supply chain availability and long-term sourcing stability. Both components share identical mechanical form factor, pin configuration, and package envelope, enabling direct PCB compatibility without layout modifications.

Electrical parameter differences exist: the LDS-CA12RI operates at 4.4V forward voltage versus 2V for the HDSP-H1G3, with reduced test current (10mA versus 20mA) and lower brightness output (6.3mcd versus 25mcd). Circuit design modifications to accommodate these electrical differences are necessary during substitution implementation.

Frequently Asked Questions (FAQ)

Q: Can the LDS-CA12RI be used as a direct pin-for-pin replacement for the HDSP-H1G3?

A: Yes, both parts use identical 10-DIP package configuration with matching pinout. Physical PCB compatibility is maintained without layout changes. However, circuit design modifications are required to accommodate the different forward voltage and current specifications.

Q: What are the key mechanical compatibility factors?

A: Both parts share identical physical dimensions (1.339" H x 0.945" W x 0.413" D), character size (1.00"), and 10-DIP package format. The display envelope and mounting footprint are equivalent, ensuring mechanical interchangeability.

Q: How do the electrical parameters differ, and what impact does this have?

A: The LDS-CA12RI requires 4.4V forward voltage compared to 2V for the HDSP-H1G3, with test current reduced from 20mA to 10mA. Brightness output is lower (6.3mcd versus 25mcd). Current-limiting resistor values and power supply voltage must be recalculated for the substitute part to ensure proper operation.

Q: Are both parts compliant with environmental and regulatory standards?

A: Both the HDSP-H1G3 and LDS-CA12RI are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Regulatory compliance is maintained with either component.

Q: Why is the HDSP-H1G3 obsolete, and what does this mean for new designs?

A: The HDSP-H1G3 is no longer manufactured by Broadcom Limited. For new designs or production continuity, the LDS-CA12RI is recommended as it maintains active production status and ensures long-term supply availability.
