LA-301VL 7-Segment LED Display - Equivalent & Substitute Parts

Part Overview

The LA-301VL is a single-character red 7-segment LED display manufactured by Rohm Semiconductor. It is a common cathode configuration designed for numeric and alphanumeric display applications. The device features a 0.31-inch character height with a 10-DIP package footprint. This part is currently in active production status with 1147 units available in stock.

Equivalent and substitute parts are identified when they maintain compatibility across critical electrical and mechanical parameters, including package type, display configuration, common pin arrangement, and forward voltage characteristics. Substitutes may vary in current draw, brightness output, and wavelength specifications while maintaining functional interchangeability in the same circuit topology.

Substitute Part Grouping Explanation

Substitution eligibility for the LA-301VL is determined by strict adherence to the following parameters:

• Package Type: Must be 10-DIP (0.209", 5.30mm) for direct PCB compatibility
• Display Configuration: Must be single-character, 7-segment format
• Common Pin Type: Must be Common Cathode
• Character Height: Must be 0.31" (8.00mm)
• Forward Voltage: Must be 2V typical
• Color: Must be Red
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The HDSP-U213 from Broadcom Limited meets all mandatory substitution criteria. Variations in current draw (10mA vs. 20mA), brightness output (10mcd vs. 5.39mcd), and wavelength (650nm vs. 635nm) are within acceptable tolerance ranges for this component category and do not prevent functional substitution.

Parameter Comparison

Engineering Selection Recommendations

Both the LA-301VL and HDSP-U213 are active production components with full ROHS3 compliance and MSL 1 ratings, indicating unrestricted moisture handling and environmental compliance across all regulatory frameworks.

The LA-301VL operates at 10mA test current with 10mcd brightness output. The HDSP-U213 operates at 20mA test current with 5.39mcd brightness output. Circuit design must account for the increased current draw of the HDSP-U213 when selecting current-limiting resistor values and power supply capacity.

Both parts share identical forward voltage (2V), package footprint (10-DIP), and display configuration (single-character, 7-segment, common cathode). Physical dimensions are nearly identical with a 0.1mm width variation (7.00mm vs. 7.10mm), which does not impact PCB layout compatibility.

Selection between these parts should be based on application-specific brightness requirements and available power budget. The LA-301VL is suitable for applications requiring lower power consumption. The HDSP-U213 is suitable for applications requiring higher brightness output despite increased power dissipation.

Frequently Asked Questions (FAQ)

Q: Can the HDSP-U213 be used as a direct replacement for the LA-301VL without circuit modification?

A: The HDSP-U213 shares identical package footprint, forward voltage, and display configuration. However, the increased test current (20mA vs. 10mA) requires verification that the current-limiting resistor and power supply can accommodate the higher current draw. The circuit topology remains unchanged.

Q: What is the significance of the wavelength difference (650nm vs. 635nm)?

A: Both wavelengths fall within the red spectrum range. The 650nm wavelength (LA-301VL) produces a standard red appearance, while the 635nm wavelength (HDSP-U213) produces a deeper red appearance. Visual perception differences are minimal in typical display applications.

Q: Are there any compliance or certification differences between these parts?

A: Both parts maintain identical ROHS3 compliance status and MSL 1 moisture sensitivity ratings. No compliance barriers exist for substitution.

Q: How do the brightness ratings compare?

A: The LA-301VL is rated at 10mcd while the HDSP-U213 is rated at 5.39mcd. The LA-301VL provides higher brightness output at lower current consumption. Application requirements for display visibility should guide selection.

Q: Is the 0.1mm width dimension difference significant?

A: The physical dimension variation (7.00mm vs. 7.10mm width) is negligible for PCB layout purposes. Both parts fit within standard 10-DIP package spacing and do not require layout modifications.

Q: What power dissipation differences should be considered?

A: The LA-301VL dissipates 40mW maximum while the HDSP-U213 dissipates 105mW maximum. Applications with thermal constraints or multiple display elements should account for the increased power dissipation of the HDSP-U213.
