Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADSP-H8E1 is determined by strict equivalence across the following critical parameters:

• Display Type: 7-Segment configuration
• Number of Characters: Single character (1)
• Digit/Alpha Size: 0.80" (20.32mm)
• Common Pin Configuration: Common Anode
• Color: Red
• Voltage - Forward (Vf) Typical: 2V
• Current - Test: 20mA
• Millicandela Rating: 30mcd
• Wavelength - Peak: 634nm
• Power Dissipation (Max): 52mW
• Package / Case: 16-DIP (0.600", 15.24mm)
• Physical Dimensions: 1.091" H x 0.787" W x 0.394" D

The HDSP-H8E1 meets all electrical and mechanical parameters required for direct substitution. Both parts are manufactured by Broadcom Limited and share identical functional specifications, physical form factor, and performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The HDSP-H8E1 is the direct equivalent for the obsolete ADSP-H8E1. Selection of the HDSP-H8E1 is supported by:

• Complete electrical parameter equivalence across all specified ratings
• Identical mechanical form factor and 16-DIP package configuration
• Active product status with current manufacturing availability
• ROHS3 compliance certification
• REACH unaffected status
• Same manufacturer (Broadcom Limited) ensuring design continuity

The transition from ADSP-H8E1 to HDSP-H8E1 requires no circuit modifications, PCB layout changes, or firmware adjustments. Pin configuration, voltage requirements, current specifications, and optical characteristics remain identical.
