LA-501VN 7-Segment LED Display - Equivalent & Substitute Parts

Part Overview

The LA-501VN is a single-character red 7-segment LED display module manufactured by Rohm Semiconductor. It is designed for numeric and alphanumeric display applications requiring a common cathode configuration. The device operates at 2V forward voltage with a 10mA test current and delivers 16mcd brightness at 650nm wavelength peak emission. The LA-501VN maintains Active product status and is RoHS3 compliant, making it suitable for current production environments. Equivalent and substitute parts are identified when component availability is constrained, manufacturing lead times extend, or design flexibility permits operation within specified electrical and mechanical tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LA-501VN is determined by strict alignment of the following parameters:

• Display Type: Must be 7-Segment
• Number of Characters: Must be 1
• Common Pin Configuration: Must be Common Cathode
• Digit/Alpha Size: Must be 0.51" (13.00mm)
• Color: Must be Red
• Wavelength - Peak: Must be 650nm
• RoHS Status: Must be RoHS3 Compliant

The TDSR1360 manufactured by Vishay Semiconductor Opto Division satisfies all substitution criteria. Both devices share identical display architecture, character count, common cathode topology, digit size, red color emission, and peak wavelength. Both maintain RoHS3 compliance and Active product status. Electrical parameters (forward voltage, test current, brightness rating) and mechanical dimensions (height, width, depth) differ within acceptable tolerances for applications where the display module functions as a functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the LA-501VN and TDSR1360 maintain Active product status and RoHS3 compliance, qualifying them for current production use. Selection between these devices depends on application-specific electrical requirements. The LA-501VN operates at 2V forward voltage with 10mA test current and delivers 16mcd brightness output. The TDSR1360 operates at 1.8V forward voltage with 1mA test current and delivers 3.6mcd brightness output. Applications requiring higher brightness output and standard current levels should specify the LA-501VN. Applications with power budget constraints or lower brightness requirements may accommodate the TDSR1360. Both devices emit at 650nm peak wavelength and maintain common cathode configuration, ensuring functional compatibility within display driver circuits designed for this topology. Package footprint differences (10-DIP 0.400" versus 10-DIP 0.600" pitch) must be evaluated against PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: Can the TDSR1360 directly replace the LA-501VN in existing designs?

A: Direct replacement requires circuit evaluation. Both devices share identical display type, character count, common cathode configuration, digit size, and peak wavelength. However, the TDSR1360 operates at lower forward voltage (1.8V vs. 2V), lower test current (1mA vs. 10mA), and lower brightness output (3.6mcd vs. 16mcd). Existing driver circuits must accommodate these electrical differences. Package pitch differences (0.600" vs. 0.400") require PCB layout verification.

Q: What are the key substitution criteria for this 7-segment display category?

A: Substitution eligibility requires matching display type (7-Segment), character count (1), common pin configuration (Common Cathode), digit size (0.51"), color (Red), and peak wavelength (650nm). RoHS3 compliance and Active product status are required for production use.

Q: How do the electrical parameters differ between these devices?

A: The LA-501VN specifies 2V forward voltage and 10mA test current with 16mcd brightness output and 480mW maximum power dissipation. The TDSR1360 specifies 1.8V forward voltage and 1mA test current with 3.6mcd brightness output and 185mW maximum power dissipation. These differences reflect different LED chip designs and optical configurations within the same physical display format.

Q: Are there package compatibility concerns?

A: Both devices use 10-DIP packaging but differ in lead pitch: LA-501VN uses 0.400" (10.16mm) pitch while TDSR1360 uses 0.600" (15.24mm) pitch. PCB footprints must match the selected device. Mechanical dimensions show minor variations in width and depth, though height remains consistent at 0.689".

Q: Do both devices meet current compliance requirements?

A: Yes. Both the LA-501VN and TDSR1360 are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8541.41.0000. Both maintain Moisture Sensitivity Level 1 (Unlimited). Both are suitable for production environments with current regulatory requirements.
