HDSP-8600 Equivalent & Substitute Parts

Part Overview

The HDSP-8600 is a single-character 7-segment LED display module manufactured by Broadcom Limited. It features a 0.80-inch green display with common anode configuration, designed for numeric and alphanumeric applications. The part is currently classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations. The HDSP-8600 operates at 2.1V forward voltage with a 10mA test current and delivers 1.5mcd brightness output.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the HDSP-8600 is determined by the following critical parameters:

• Display Configuration: 7-segment, single character, common anode topology
• Physical Compatibility: 0.80-inch digit size and overall form factor dimensions
• Electrical Specifications: Forward voltage range (2.1V–2.2V), test current capability (10mA–20mA), and wavelength consistency (565nm–566nm green spectrum)
• Package Compatibility: DIP package format with 12 active leads and 0.600-inch pitch

Substitute parts must maintain common anode configuration and green LED color. Variations in test current, brightness rating, and power dissipation are acceptable provided the part operates within the specified voltage and wavelength parameters and maintains mechanical compatibility with the original 18-DIP or compatible 16-DIP footprint.

Engineering Selection Recommendations

HDSP-815G (Broadcom Limited): This part is the manufacturer-recommended substitute and maintains Broadcom platform continuity. It operates at identical forward voltage (2.1V) and peak wavelength (566nm) as the HDSP-8600. The HDSP-815G is active in production status and ROHS3 compliant. The primary difference is the 16-DIP package versus the original 18-DIP format; however, the 12 active leads remain functionally equivalent. Test current increases to 20mA with corresponding brightness improvement to 3.3mcd and reduced power dissipation to 65mW. This part is suitable for direct replacement in applications where the DIP package footprint can accommodate the pin count reduction.

SA08-12GWA (Kingbright): This part provides cross-manufacturer substitution with identical physical dimensions and 18-DIP package matching. It maintains the same 0.80-inch digit size and common anode configuration. Forward voltage is marginally higher at 2.2V (within acceptable tolerance), and peak wavelength is 565nm (within green spectrum range). The SA08-12GWA delivers significantly higher brightness at 13mcd with 20mA test current and the lowest power dissipation at 62.5mW. This part is active in production and ROHS3 compliant. Selection is appropriate for applications requiring higher brightness output or cross-manufacturer sourcing flexibility.

Frequently Asked Questions (FAQ)

Q: Can the HDSP-815G be used as a direct replacement for the HDSP-8600?

A: The HDSP-815G is functionally compatible as a substitute. Both parts share identical forward voltage (2.1V), wavelength (566nm), digit size (0.80"), and common anode configuration. The primary difference is the package format: HDSP-815G uses 16-DIP versus HDSP-8600's 18-DIP. The 12 active leads are equivalent; the 6 unused pins in the 16-DIP package do not affect electrical operation. PCB layout must accommodate the different pin count.

Q: What is the brightness difference between the HDSP-8600 and substitute parts?

A: The HDSP-8600 operates at 1.5mcd brightness with 10mA test current. The HDSP-815G delivers 3.3mcd at 20mA, and the SA08-12GWA delivers 13mcd at 20mA. Higher brightness ratings indicate increased light output intensity. Selection depends on application visibility requirements and power budget constraints.

Q: Are the substitute parts mechanically compatible with the original HDSP-8600 footprint?

A: The HDSP-815G uses a 16-DIP package versus the original 18-DIP, requiring PCB layout modification. The SA08-12GWA maintains the 18-DIP package format with dimensions of 1.091" H x 0.787" W x 0.331" D, which is mechanically equivalent to the HDSP-8600 (1.090" H x 0.786" W x 0.330" D) within standard manufacturing tolerances.

Q: What is the voltage tolerance for forward voltage substitution?

A: The HDSP-8600 operates at 2.1V forward voltage. The HDSP-815G matches this specification exactly at 2.1V. The SA08-12GWA operates at 2.2V, representing a 0.1V increase. This difference is within typical LED forward voltage tolerance ranges and does not prevent substitution in most applications.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the HDSP-815G and SA08-12GWA are ROHS3 compliant. The original HDSP-8600 RoHS status is not specified in the available documentation.

Q: What is the wavelength difference between the substitute parts?

A: The HDSP-8600 and HDSP-815G both operate at 566nm peak wavelength. The SA08-12GWA operates at 565nm. Both wavelengths fall within the green LED spectrum and are visually indistinguishable in standard applications.
