TDSL5160 7-Segment LED Display - Equivalent & Substitute Parts

Part Overview

The TDSL5160 is a single-character red 7-segment LED display manufactured by Vishay Semiconductor Opto Division. This common cathode display operates at 1.8V forward voltage with a 2mA test current and features a 0.51" digit height. The component is actively produced and ROHS3 compliant, making it suitable for applications requiring compact numeric display modules in standard 10-DIP packaging.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit operation within the electrical and mechanical tolerances of alternative manufacturers' offerings.

Substitute Part Grouping Explanation

The LAP-601VL from Rohm Semiconductor qualifies as a substitute based on the following critical parameters:

• Display Configuration: Both parts are single-character, common cathode, red 7-segment displays
• Package Type: Both use 10-DIP packaging, ensuring mechanical and electrical pin compatibility
• Compliance: Both are ROHS3 compliant and REACH unaffected
• Operational Voltage Range: Forward voltages of 1.8V (TDSL5160) and 1.9V (LAP-601VL) are within acceptable tolerance for most circuit designs
• Color and Wavelength: Both emit red light in the 635nm–650nm range, suitable for identical applications

Substitution is valid where circuit design accommodates the LAP-601VL's higher test current (10mA vs. 2mA) and increased brightness (36mcd vs. 0.40mcd).

Parameter Comparison

Engineering Selection Recommendations

Both the TDSL5160 and LAP-601VL are active products with ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards.

The TDSL5160 is the primary choice for applications requiring lower power consumption and minimal brightness. The LAP-601VL serves as a direct substitute where higher brightness (36mcd vs. 0.40mcd) and increased current capacity (10mA vs. 2mA) are acceptable or beneficial. The 0.1V difference in forward voltage (1.9V vs. 1.8V) is negligible in standard circuit designs with current-limiting resistors.

Physical dimensions differ slightly: the LAP-601VL features a larger digit height (0.58" vs. 0.51") and different DIP body dimensions. Verify mechanical fit within the target application's PCB layout and enclosure constraints before substitution.

Frequently Asked Questions (FAQ)

Q: Can LAP-601VL replace TDSL5160 in existing designs without circuit modification?

A: Pin compatibility is maintained through identical 10-DIP packaging and common cathode configuration. However, the LAP-601VL's higher test current (10mA vs. 2mA) requires circuit validation. Existing current-limiting resistors may need adjustment to prevent over-current conditions or to achieve desired brightness levels.

Q: What is the significance of the 0.1V difference in forward voltage?

A: The difference between 1.8V and 1.9V is within standard tolerance for LED circuit design. Most applications using series current-limiting resistors will accommodate this variation without performance degradation.

Q: Are there mechanical compatibility concerns?

A: Both parts use 10-DIP packaging with identical pin spacing. However, the LAP-601VL has a larger digit height (0.58" vs. 0.51") and different body dimensions (19.00mm × 12.50mm × 8.00mm vs. 17.50mm × 12.25mm × 6.40mm). Confirm fit within the PCB footprint and enclosure before substitution.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both TDSL5160 and LAP-601VL are ROHS3 compliant and REACH unaffected, meeting current environmental and safety standards for electronic components.

Q: What is the brightness difference between these parts?

A: The LAP-601VL provides significantly higher brightness at 36mcd compared to the TDSL5160 at 0.40mcd. This difference may require circuit adjustment to prevent excessive brightness or to meet specific visibility requirements.
