HDSP-H3A3 Equivalent & Substitute Parts

Part Overview

The HDSP-H3A3 is a single-character red 7-segment LED display module manufactured by Broadcom Limited. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The display operates at 2V forward voltage with a 20mA test current and is housed in a 10-DIP package measuring 0.551" H × 0.295" W × 0.335" D (14.00mm × 7.50mm × 8.50mm). Identifying compatible alternatives ensures design continuity and supply chain reliability.

Substitute Part Grouping Explanation

Substitution eligibility for the HDSP-H3A3 is determined by strict equivalence across the following critical parameters:

Display configuration: 7-segment, single character, common cathode topology Electrical specifications: 2V forward voltage, 20mA test current, 52mW maximum power dissipation Physical form factor: 0.36" digit size, 10-DIP package with 0.200" (5.08mm) pin spacing Mechanical dimensions: 0.551" H × 0.295" W × 0.335" D (14.00mm × 7.50mm × 8.50mm) Compliance: ROHS3 compliant, MSL 1 rating

The HDSP-H3E3 meets all substitution criteria as a direct equivalent. Both parts share identical mechanical packaging, electrical operating parameters, and regulatory compliance status. The primary distinction is product lifecycle status: HDSP-H3A3 is obsolete while HDSP-H3E3 is active production.

Parameter Comparison

Engineering Selection Recommendations

The HDSP-H3E3 is the direct substitute for HDSP-H3A3 applications. Both components maintain identical mechanical and electrical specifications, ensuring pin-for-pin compatibility and functional equivalence in circuit designs. The HDSP-H3E3 carries active product status from Broadcom Limited, providing assured supply chain availability and ongoing manufacturing support compared to the obsolete HDSP-H3A3.

Both parts maintain ROHS3 compliance and MSL 1 rating, satisfying regulatory and environmental requirements for industrial and commercial applications. The HDSP-H3E3 is the recommended selection for new designs and production continuity where HDSP-H3A3 components are no longer available.

Frequently Asked Questions (FAQ)

Q: Can HDSP-H3E3 replace HDSP-H3A3 in existing designs? A: Yes. The HDSP-H3E3 is a direct substitute with identical pin configuration, package dimensions, and electrical operating parameters. No circuit modifications are required.

Q: What are the differences between HDSP-H3A3 and HDSP-H3E3? A: The primary differences are product lifecycle status (HDSP-H3A3 is obsolete; HDSP-H3E3 is active) and minor variations in luminous intensity (13mcd vs. 15mcd) and peak wavelength (644nm vs. 634nm). Both operate at identical voltage and current specifications.

Q: Are there any package or pinout differences? A: No. Both components use the 10-DIP package with 0.200" (5.08mm) pin spacing and identical physical dimensions of 0.551" H × 0.295" W × 0.335" D (14.00mm × 7.50mm × 8.50mm).

Q: Do both parts meet the same compliance standards? A: Yes. Both HDSP-H3A3 and HDSP-H3E3 are ROHS3 compliant with MSL 1 rating, meeting equivalent regulatory and environmental requirements.

Q: Why is HDSP-H3A3 listed as obsolete? A: Broadcom Limited has discontinued the HDSP-H3A3 product line. The HDSP-H3E3 represents the active equivalent for ongoing production and new design applications.
