Engineering Selection Recommendations

The HDSP-7403-GH000 is the direct substitute for the obsolete HDSP-7403-EF000. Selection is based on the following engineering factors:

Product status: The HDSP-7403-GH000 maintains active production status, ensuring supply chain continuity and long-term availability compared to the obsolete HDSP-7403-EF000.

Regulatory compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements without modification to existing designs.

Electrical compatibility: Forward voltage specification of 2V on the substitute part falls within the acceptable operating range for circuits designed for the 2.2V original part. Test current remains constant at 20mA.

Physical and functional equivalence: Identical package type, physical dimensions, digit size, display configuration, and common cathode topology ensure direct PCB compatibility and circuit-level interchangeability without design modification.

Optical characteristics: The substitute part exhibits higher luminous intensity (2.2mcd versus 0.98mcd) and operates within the yellow wavelength spectrum (591nm versus 583nm), maintaining visual consistency while providing improved brightness performance.

Thermal performance: Maximum power dissipation of 50mW on the substitute part is lower than the original 80mW specification, resulting in reduced thermal load on the circuit.

Frequently Asked Questions (FAQ)

Q: Can the HDSP-7403-GH000 be used as a direct replacement for the HDSP-7403-EF000 without circuit modification?

A: Yes. The HDSP-7403-GH000 is electrically and mechanically compatible with the HDSP-7403-EF000. Identical package type, pin configuration, digit size, and common cathode topology enable direct substitution on existing PCBs without design changes.

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

A: The primary differences are product status (active versus obsolete), forward voltage (2V versus 2.2V), luminous intensity (2.2mcd versus 0.98mcd), peak wavelength (591nm versus 583nm), and maximum power dissipation (50mW versus 80mW). All differences remain within acceptable operating parameters for substitution.

Q: Will the substitute part display the same brightness as the original?

A: The HDSP-7403-GH000 exhibits higher luminous intensity (2.2mcd) compared to the HDSP-7403-EF000 (0.98mcd), resulting in increased brightness. Both parts operate within the yellow color spectrum with minimal perceptual difference in hue.

Q: Are there any compliance or regulatory concerns with using the substitute part?

A: No. Both parts maintain ROHS3 compliance and REACH unaffected status. No additional regulatory documentation or design review is required for substitution.

Q: What is the impact of the lower forward voltage specification on the substitute part?

A: The 2V forward voltage on the HDSP-7403-GH000 is lower than the 2.2V specification on the original part. This difference is within normal operating tolerances for LED display circuits and does not require circuit redesign. Existing current-limiting resistor values will continue to function correctly.

Q: Is the 10-DIP package format identical between both parts?

A: Yes. Both parts use the 10-DIP (0.200", 5.08mm) package with identical physical dimensions of 0.500" H x 0.300" W x 0.240" D. Pin spacing and PCB footprint compatibility are guaranteed.
