Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HDSP-7511-CD000 is determined by the following critical parameters:

• Display configuration: 7-segment, single character, common anode
• Physical compatibility: 0.30" character size, 10-DIP package footprint
• Electrical interface: Red LED color, forward voltage range, current requirements
• Regulatory compliance: RoHS3 compliance, REACH status

The HDSP-7511-HI000 qualifies as a direct substitute based on matching display type, character count, common anode configuration, character size, and 10-DIP package specification. Both parts share the same base product number (HDSP-7511) and maintain equivalent regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

The HDSP-7511-HI000 is the manufacturer-recommended substitute for the obsolete HDSP-7511-CD000. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity in applications requiring these certifications.

The substitute part operates at higher forward voltage (2.05V vs. 1.7V) and increased test current (20mA vs. 5mA), resulting in higher brightness output (1.8mcd vs. 1.05mcd). The peak wavelength differs slightly (631nm vs. 635nm), remaining within the red spectrum classification. Maximum power dissipation is lower in the substitute (37.5mW vs. 52mW).

Circuit designs must accommodate the electrical parameter differences, particularly forward voltage and current requirements, to ensure proper operation and component longevity. The active product status of the HDSP-7511-HI000 provides superior long-term availability compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can the HDSP-7511-HI000 be used as a direct pin-for-pin replacement?

A: Yes. Both parts use identical 10-DIP package configuration with matching pinout. Physical installation is compatible without modification.

Q: What electrical adjustments are required when substituting the HDSP-7511-HI000?

A: Circuit design must account for the higher forward voltage (2.05V vs. 1.7V) and increased test current (20mA vs. 5mA). Current-limiting resistor values and power supply specifications may require recalculation to maintain proper display brightness and component reliability.

Q: Are there compliance differences between the main part and substitute?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating.

Q: Why does the substitute part have higher brightness output?

A: The HDSP-7511-HI000 operates at increased forward voltage and current specifications, resulting in higher millicandela rating (1.8mcd vs. 1.05mcd). This provides improved visibility in applications requiring brighter display output.

Q: Is the wavelength difference between parts significant?

A: The wavelength difference (631nm vs. 635nm) represents a minor shift within the red spectrum. Both parts are classified as red LEDs and are visually equivalent for standard display applications.
