Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HDSP-8601 is determined by the following criteria:

Display configuration must match: single character, 7-segment, green color, common anode topology, and 0.80" digit size. Package type must be 18-DIP (0.600", 15.24mm) to ensure mechanical and electrical compatibility with existing PCB layouts and connector interfaces.

Electrical parameters within acceptable ranges include forward voltage (Vf) tolerance of ±0.2V from the nominal specification, test current up to 20mA, and peak wavelength within the green spectrum (560–570nm). Compliance certifications including RoHS3 and MSL rating of 1 are required.

The SA08-11GWA from Kingbright meets these substitution criteria across all specified parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the HDSP-8601 and SA08-11GWA maintain active product status and full RoHS3 compliance with MSL rating of 1. The SA08-11GWA is suitable as a direct substitute where the application can accommodate the electrical parameter variations: forward voltage increase of 0.1V (2.1V to 2.2V) and test current increase of 10mA (10mA to 20mA). The SA08-11GWA provides higher luminous intensity (13mcd versus 1.5mcd) and lower maximum power dissipation (62.5mW versus 105mW), making it advantageous for brightness-critical or power-constrained applications. Both components share identical mechanical dimensions and package configuration, ensuring direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can the SA08-11GWA replace the HDSP-8601 in existing designs?

A: Yes. Both components share identical 18-DIP package dimensions, digit size (0.80"), display type (7-segment), color (green), and common anode configuration. Electrical parameter differences (Vf: 2.1V to 2.2V; test current: 10mA to 20mA) fall within acceptable substitution ranges for this display category.

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

A: The SA08-11GWA operates at 2.2V forward voltage compared to 2.1V for the HDSP-8601, and specifies 20mA test current versus 10mA. Peak wavelength differs by 1nm (565nm versus 566nm), remaining within the green spectrum. The SA08-11GWA delivers significantly higher brightness (13mcd versus 1.5mcd).

Q: Are both parts RoHS3 compliant?

A: Yes. Both the HDSP-8601 and SA08-11GWA carry ROHS3 Compliant certification and MSL rating of 1 (Unlimited moisture sensitivity level).

Q: Does package type affect substitution compatibility?

A: No. Both components use identical 18-DIP (0.600", 15.24mm) packaging with 12 leads, ensuring mechanical and electrical interface compatibility on PCBs designed for either part.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. The SA08-11GWA offers higher brightness output and lower power dissipation, making it suitable for visibility-critical or power-optimized applications. The HDSP-8601 remains available for designs requiring the original specification parameters.
