Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HDSP-C5E1 are qualified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Display Type: 7-Segment configuration
• Number of Characters: Single character
• Common Pin Configuration: Common Anode
• Color: Red
• Package Type: 10-DIP (0.600", 15.24mm)

Secondary Electrical Parameters:

• Voltage - Forward (Vf): Range 1.9V to 2V acceptable
• Current - Test: 10mA to 20mA acceptable
• Wavelength - Peak: 635nm to 650nm acceptable

Tertiary Considerations:

• Physical dimensions must accommodate PCB layout constraints
• Digit height variations within 0.52" to 0.57" range
• Product status and compliance certifications

The substitute parts identified meet all primary compatibility criteria and fall within acceptable ranges for secondary electrical parameters, ensuring direct functional replacement capability in common anode 7-segment display applications.

Parameter Comparison

Engineering Selection Recommendations

LAP-601VB (Rohm Semiconductor): This substitute offers the highest brightness rating at 36mcd with a slightly lower forward voltage of 1.9V and reduced test current of 10mA. The part is currently in active production status with ROHS3 compliance certification. The increased digit height of 0.57" and overall physical dimensions require PCB layout verification. The MSL rating of 3 (168 Hours) indicates standard moisture sensitivity handling requirements. This option is suitable for applications where increased brightness is beneficial and PCB space accommodates the larger form factor.

LDS-A5644RI (Lumex Opto/Components Inc.): This substitute maintains electrical parameters closely aligned with the original HDSP-C5E1, with identical 2V forward voltage and reduced test current of 10mA. The part is in active production with ROHS3 compliance and MSL rating of 1 (Unlimited), matching the original moisture sensitivity specification. The digit height of 0.56" and physical dimensions fall between the original and the LAP-601VB option, providing a balanced alternative. The millicandela rating of 4.6mcd is comparable to the original specification.

Both substitute parts maintain the critical 10-DIP package configuration and common anode architecture required for direct functional replacement. Selection between alternatives depends on specific brightness requirements, available PCB space, and production status preferences.

Frequently Asked Questions (FAQ)

Q: Can the LAP-601VB and LDS-A5644RI be used interchangeably with the HDSP-C5E1?

A: Both parts share the same 10-DIP package footprint and common anode configuration, enabling direct PCB mounting compatibility. However, the increased digit heights (0.57" and 0.56" respectively versus 0.52" original) and slightly different physical dimensions require verification that the display window or bezel accommodates the larger form factor. Electrical parameters fall within acceptable operating ranges for common anode 7-segment applications.

Q: What are the key electrical differences between the substitute parts?

A: The LAP-601VB operates at 1.9V forward voltage with 10mA test current and delivers significantly higher brightness at 36mcd. The LDS-A5644RI maintains the original 2V forward voltage with 10mA test current and provides comparable brightness at 4.6mcd. Both substitutes reduce test current from the original 20mA specification, resulting in lower power dissipation during operation.

Q: Are there compliance or regulatory differences between the options?

A: Both substitute parts carry ROHS3 compliance certification and REACH Unaffected status, matching the regulatory profile of the original HDSP-C5E1. The LAP-601VB specifies MSL 3 (168 Hours) moisture sensitivity, while the LDS-A5644RI matches the original MSL 1 (Unlimited) specification. For applications with strict moisture handling requirements, the LDS-A5644RI aligns with the original specification.

Q: How do wavelength differences affect display appearance?

A: The original HDSP-C5E1 operates at 640nm peak wavelength. The LAP-601VB operates at 650nm (deeper red), while the LDS-A5644RI operates at 635nm (brighter red). These wavelength variations produce subtle color differences perceptible in direct comparison but remain within the red spectrum classification for standard display applications.

Q: What is the impact of the digit height increase in substitute parts?

A: The LAP-601VB digit height of 0.57" and LDS-A5644RI digit height of 0.56" represent increases of approximately 9% and 8% respectively over the original 0.52" specification. This affects visual display size and requires confirmation that the display window, bezel opening, or mechanical housing accommodates the larger digit dimensions without obstruction or misalignment.
