HDSP-H511 Equivalent & Substitute Parts

Part Overview

The HDSP-H511 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 2.1V forward voltage with a 10mA test current and displays characters at 0.56" (14.22mm) height. This part is currently active in production and widely used in legacy and new electronic display systems. Substitute parts may be required due to inventory constraints, packaging preferences, or design optimization needs while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the HDSP-H511 is determined by the following critical parameters:

• Display Type & Configuration: Must be 7-segment, single character, common anode
• Character Size: Must be 0.56" (14.22mm) digit/alpha size
• Color & Wavelength: Must be green with peak wavelength in the 565-566nm range
• Electrical Characteristics: Forward voltage must be 2.1V (typical); test current tolerance allows variation
• Compliance & Environmental: Must maintain ROHS3 compliance and MSL 1 rating

The LTS-6460G from Lite-On Inc. meets these substitution criteria. While it differs in package type (10-DIP vs. 18-DIP), test current (20mA vs. 10mA), and physical height (0.750" vs. 0.670"), these variations remain within acceptable substitution parameters for common anode 7-segment green LED displays of 0.56" character size.

Parameter Comparison

Engineering Selection Recommendations

Both the HDSP-H511 and LTS-6460G maintain ROHS3 compliance and MSL 1 ratings, ensuring equivalent environmental and regulatory standing. The HDSP-H511 is the primary part with active production status and established supply. The LTS-6460G serves as a qualified substitute when the HDSP-H511 is unavailable.

Selection between these parts should account for:

• Package Pin Count: The HDSP-H511 uses 18-DIP while the LTS-6460G uses 10-DIP. PCB layout and routing must accommodate the selected package.
• Current Requirements: The LTS-6460G operates at 20mA test current versus 10mA for the HDSP-H511. Circuit design must support the higher current draw if substituting.
• Physical Dimensions: The LTS-6460G is 0.080" taller (0.750" vs. 0.670"). Mechanical clearance in the enclosure must be verified.
• Power Dissipation: The LTS-6460G dissipates 75mW maximum versus 105mW for the HDSP-H511, resulting in lower thermal load.

Both parts are functionally equivalent for 7-segment green LED display applications requiring 0.56" character size and common anode configuration.

Frequently Asked Questions (FAQ)

Q: Can the LTS-6460G directly replace the HDSP-H511 on an existing PCB?

A: Direct PCB replacement is not possible due to different package types (10-DIP vs. 18-DIP). The pin configurations differ, requiring circuit redesign or adapter solutions. Mechanical height differences (0.750" vs. 0.670") must also be evaluated for enclosure fit.

Q: Are the electrical characteristics compatible?

A: Yes. Both parts operate at 2.1V forward voltage (typical) and are configured as common anode 7-segment displays. The LTS-6460G requires 20mA test current compared to 10mA for the HDSP-H511. Circuit current-limiting resistors must be recalculated if substituting.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the HDSP-H511 and LTS-6460G are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings. They are equivalent from a regulatory and environmental standpoint.

Q: What is the wavelength difference between these parts?

A: The HDSP-H511 has a peak wavelength of 566nm while the LTS-6460G is 565nm. This 1nm difference is negligible for visual perception and both display identical green color characteristics.

Q: Which part should be selected for new designs?

A: The HDSP-H511 is the primary recommendation for new designs due to active production status and established supply chain. The LTS-6460G is reserved for substitution when the primary part is unavailable or when the 10-DIP package and lower power dissipation are design advantages.
