HDSP-511E 7-Segment LED Display - Equivalent & Substitute Parts

Part Overview

The HDSP-511E is a single-character red 7-segment LED display module manufactured by Broadcom Limited. This common anode display operates at 2.05V forward voltage with a 20mA test current and features a 0.56" digit height. The component is classified as Active product status and is ROHS3 compliant. Alternative equivalent parts may be required due to inventory constraints, supply chain considerations, or specific application requirements where substitute specifications remain within acceptable operational parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HDSP-511E is determined by the following critical parameters:

Primary Compatibility Criteria:

• Display Type: 7-Segment configuration
• Number of Characters: Single character
• Common Pin Configuration: Common Anode
• Color: Red
• Package / Case: 10-DIP (0.600", 15.24mm)

Secondary Operational Parameters:

• Voltage - Forward (Vf): Range tolerance around 2.05V nominal
• Current - Test: 20mA specification
• Wavelength - Peak: Red spectrum (620-640nm range)

The SA52-11EWA from Kingbright meets all primary compatibility criteria and operates within acceptable secondary parameter ranges. Both parts share identical package geometry, pin configuration, and functional classification, enabling direct substitution in circuit applications where the specified electrical characteristics are compatible with design requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the HDSP-511E and SA52-11EWA are Active product status components with ROHS3 compliance and MSL Level 1 rating, indicating equivalent environmental and regulatory qualification. Selection between these parts should be based on the following provided specifications:

HDSP-511E (Broadcom Limited): Larger digit height (0.56"), lower power dissipation (60mW maximum), and lower luminous intensity (4.1mcd) at 635nm wavelength peak.

SA52-11EWA (Kingbright): Smaller digit height (0.52"), higher power dissipation (75mW maximum), and higher luminous intensity (6.4mcd) at 627nm wavelength peak.

Both components operate at compatible forward voltages (2.05V vs. 2V) and identical test current (20mA). The 10-DIP package footprint and pin configuration are identical, ensuring mechanical and electrical compatibility in circuit board layouts. Component selection should align with specific application requirements regarding display size visibility and brightness characteristics.

Frequently Asked Questions (FAQ)

Q: Can SA52-11EWA directly replace HDSP-511E in existing circuit designs?

A: Yes. Both components share identical 10-DIP package geometry, common anode pin configuration, and compatible electrical operating parameters (2.05V vs. 2V forward voltage, 20mA test current). Direct substitution is mechanically and electrically feasible.

Q: What are the key differences between these two parts?

A: The primary differences are digit height (0.56" vs. 0.52"), luminous intensity (4.1mcd vs. 6.4mcd), and wavelength peak (635nm vs. 627nm). Power dissipation also differs (60mW vs. 75mW maximum). These variations may affect visual display characteristics and thermal considerations in the application circuit.

Q: Are both parts RoHS compliant?

A: Yes. Both HDSP-511E and SA52-11EWA are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating, meeting equivalent environmental and regulatory standards.

Q: Does the 0.04" digit height difference impact PCB layout?

A: No. Both components use identical 10-DIP (0.600", 15.24mm) package specifications. The digit height difference refers only to the visible LED segment size, not the physical package footprint or pin spacing. PCB layouts remain unchanged.

Q: Which part should be selected for higher brightness applications?

A: The SA52-11EWA provides higher luminous intensity (6.4mcd vs. 4.1mcd), making it suitable for applications requiring greater display brightness. However, this results in higher maximum power dissipation (75mW vs. 60mW), which should be considered in thermal design.
