ADSP-H3G1 Equivalent & Substitute Parts

Part Overview

The ADSP-H3G1 is a single-character 7-segment LED display module manufactured by Broadcom Limited. It features a green light-emitting diode with common anode configuration, designed for numeric and alphanumeric display applications. The device operates at 2V forward voltage with a 20mA test current and produces 5mcd luminous intensity at a peak wavelength of 570nm. The ADSP-H3G1 is classified as obsolete, making identification of functionally equivalent active alternatives essential for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADSP-H3G1 is determined by strict equivalence across the following electrical and mechanical parameters:

• Display configuration: Single-character 7-segment format
• Color and wavelength: Green at 570nm peak wavelength
• Common pin type: Common anode architecture
• Electrical specifications: 2V forward voltage and 20mA test current
• Luminous intensity: 5mcd rating
• Package type: 10-DIP (0.200", 5.08mm) dual inline package
• Physical envelope: 0.551" H x 0.295" W x 0.335" D

The HDSP-H3G1 meets all these criteria and is classified as an active product, making it a direct functional equivalent for the obsolete ADSP-H3G1.

Parameter Comparison

Engineering Selection Recommendations

The HDSP-H3G1 is the direct equivalent for the obsolete ADSP-H3G1. Both parts are manufactured by Broadcom Limited and share identical electrical and mechanical specifications across all critical parameters: display type, character count, size, color, common anode configuration, forward voltage, test current, luminous intensity, wavelength, power dissipation, and package format.

The HDSP-H3G1 carries active product status and holds ROHS3 compliance and REACH unaffected certification, providing regulatory compliance advantages for new designs and production applications. The identical 10-DIP package and physical dimensions ensure direct pin-compatible replacement without circuit board modifications.

Frequently Asked Questions (FAQ)

Q: Can the HDSP-H3G1 replace the ADSP-H3G1 in existing designs?

A: Yes. The HDSP-H3G1 is electrically and mechanically identical to the ADSP-H3G1. Both devices operate at 2V forward voltage, 20mA test current, and feature the same 10-DIP package with identical pinout and physical dimensions. Direct substitution is possible without circuit modifications.

Q: What is the significance of the ADSP-H3G1 being obsolete?

A: Obsolete status indicates the part is no longer manufactured or supported by Broadcom Limited. The HDSP-H3G1 is the active equivalent and should be used for new designs and ongoing production to ensure supply chain continuity and manufacturer support.

Q: Are there any compliance differences between the two parts?

A: The HDSP-H3G1 carries ROHS3 compliance and REACH unaffected certification. The ADSP-H3G1 specifications do not include these certifications. For applications requiring regulatory compliance documentation, the HDSP-H3G1 is the appropriate selection.

Q: Do both parts use the same 10-DIP package?

A: Yes. Both the ADSP-H3G1 and HDSP-H3G1 use the 10-DIP (0.200", 5.08mm) package with identical physical dimensions of 0.551" H x 0.295" W x 0.335" D. They are pin-compatible and mechanically interchangeable.

Q: What are the key electrical parameters that define substitution?

A: Substitution is based on matching display type (7-segment), character count (1), color (green), common pin configuration (common anode), forward voltage (2V), test current (20mA), luminous intensity (5mcd), peak wavelength (570nm), and package type (10-DIP). The HDSP-H3G1 matches all these parameters.
