Key Parameters

Substitute Part Grouping Explanation

Substitution of the HDSP-7501-CDZ00 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Forward voltage (Vf): 2.05V
• Test current: 20mA
• Power dissipation maximum: 75mW
• Millicandela rating: 4.5mcd
• Peak wavelength: 631nm

Mechanical Parameters:

• Display type: 7-Segment
• Common pin configuration: Common Anode
• Digit/Alpha size: 0.30" (7.62mm)
• Physical dimensions: 0.500" H x 0.300" W x 0.240" D
• Package type: 10-DIP (0.200", 5.08mm)

Functional Parameters:

• Number of characters: 1
• Color: Red
• Series family: HDSP-750x

Substitute parts must match all parameters listed above to ensure direct functional and mechanical compatibility without circuit redesign or PCB layout modification.

Parameter Comparison

Engineering Selection Recommendations

The HDSP-7501-GHZ00 is the manufacturer-recommended substitute for the obsolete HDSP-7501-CDZ00. All critical electrical, mechanical, and functional parameters are identical between the two parts, ensuring direct compatibility in existing circuit designs and PCB layouts.

The primary distinction between the main part and substitute is product status: the HDSP-7501-CDZ00 is obsolete, while the HDSP-7501-GHZ00 is active. The substitute part carries ROHS3 compliance certification and MSL rating of 1 (Unlimited), indicating improved environmental and regulatory alignment with current manufacturing standards. The substitute is supplied in tube packaging rather than unspecified packaging for the obsolete variant.

For new designs and production continuity, the HDSP-7501-GHZ00 is the appropriate selection. For legacy system repairs requiring exact original specifications, the HDSP-7501-CDZ00 remains functionally equivalent where inventory permits.

Frequently Asked Questions (FAQ)

Q: Can the HDSP-7501-GHZ00 be used as a direct replacement for the HDSP-7501-CDZ00 in existing designs?

A: Yes. All electrical parameters (forward voltage, test current, power dissipation, luminous intensity, and wavelength) and mechanical parameters (package type, dimensions, digit size, and pin configuration) are identical. No circuit redesign or PCB layout modification is required.

Q: What is the difference between the HDSP-7501-CDZ00 and HDSP-7501-GHZ00?

A: The HDSP-7501-CDZ00 is obsolete, while the HDSP-7501-GHZ00 is active. The substitute part includes ROHS3 compliance certification and MSL rating of 1. Packaging is specified as tube for the substitute. All functional and electrical specifications are equivalent.

Q: Are there any pin configuration differences between these parts?

A: No. Both parts use 10-DIP (0.200", 5.08mm) package with common anode configuration. Pin assignments and electrical characteristics are identical.

Q: What is the significance of the ROHS3 compliance on the HDSP-7501-GHZ00?

A: ROHS3 compliance indicates the substitute part meets current European Union Restriction of Hazardous Substances regulations. This is relevant for applications subject to environmental and regulatory compliance requirements.

Q: Can these parts be used interchangeably in high-volume production?

A: Yes, provided the HDSP-7501-GHZ00 is available in required quantities. The active product status of the substitute ensures ongoing manufacturing availability, whereas the obsolete HDSP-7501-CDZ00 has limited inventory (3850 pcs reported in stock).

Q: Are there any thermal or environmental considerations when substituting these parts?

A: Both parts share identical power dissipation specifications (75mW maximum). The HDSP-7501-GHZ00 carries MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
