HDSP-7501-CD000 Equivalent & Substitute Parts
Part Overview
The HDSP-7501-CD000 is a single-character red 7-segment LED display module manufactured by Broadcom Limited. This component is designed for numeric and alphanumeric display applications requiring a common anode configuration. The part operates at 2V forward voltage with a 20mA test current and features a 0.30-inch character height in a compact 10-DIP package.
The HDSP-7501-CD000 is classified as obsolete. Identifying suitable substitute components is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for legacy systems.

Substitute Part Grouping Explanation
Substitution eligibility for the HDSP-7501-CD000 is determined by the following critical parameters:
- Display Configuration: 7-segment, single character, common anode
- Package Type: 10-DIP (0.200", 5.08mm) pinout compatibility
- Character Height: 0.30" (7.62mm) for form factor compatibility
- Color: Red LED emission
- Electrical Compatibility: Forward voltage and test current within acceptable operating ranges for the application
- Compliance: RoHS3 compliance and moisture sensitivity level (MSL 1)
The HDSP-7501-GH000 qualifies as a direct substitute based on matching display type, common anode configuration, package format, character height, color, and compliance certifications. Minor variations in forward voltage (2.05V vs. 2V), millicandela rating, wavelength, and power dissipation are within acceptable tolerances for equivalent 7-segment display modules in this product category.

Engineering Selection Recommendations
The HDSP-7501-GH000 is the manufacturer-recommended substitute for the obsolete HDSP-7501-CD000. Both components are manufactured by Broadcom Limited and maintain identical mechanical and electrical compatibility within the specified 10-DIP package format.
The HDSP-7501-GH000 offers the advantage of active product status, ensuring continued availability and supply chain support. Both parts maintain ROHS3 compliance and MSL 1 moisture sensitivity rating, meeting regulatory and environmental requirements.
The forward voltage differential of 0.05V (2.05V vs. 2V) and the reduced power dissipation (75mW vs. 105mW) in the substitute part represent improved efficiency characteristics. The wavelength variation (631nm vs. 635nm) remains within the red LED spectrum and does not affect functional compatibility for standard display applications.
Frequently Asked Questions (FAQ)
Q: Can the HDSP-7501-GH000 be used as a direct replacement for the HDSP-7501-CD000?
A: Yes. Both components share identical 10-DIP package pinouts, common anode configuration, 0.30-inch character height, and red LED color. The electrical parameters are compatible for equivalent display applications.
Q: What is the significance of the forward voltage difference between the two parts?
A: The forward voltage difference of 0.05V (2.05V vs. 2V) is negligible for most circuit designs. Standard current-limiting resistor calculations will accommodate this minor variation without requiring circuit redesign.
Q: Does the wavelength difference affect display appearance?
A: Both parts emit red light within the standard red LED spectrum (631nm vs. 635nm). The visual difference is imperceptible in typical display applications.
Q: Why is the HDSP-7501-CD000 listed as obsolete?
A: The HDSP-7501-CD000 has been discontinued by the manufacturer. The HDSP-7501-GH000 represents the current active product offering from Broadcom Limited for this display module category.
Q: Are there any compliance or certification differences between the two parts?
A: No. Both components maintain identical RoHS3 compliance status and MSL 1 moisture sensitivity rating, meeting the same regulatory and environmental standards.
Q: What packaging format is available for the HDSP-7501-GH000?
A: The HDSP-7501-GH000 is supplied in tube packaging, suitable for automated assembly and component handling processes.
