Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QLA764BHGY is determined by the following critical parameters:

• Physical Configuration: 3-high LED assembly with Green, Red, and Yellow color combination
• Lens Geometry: 3mm diameter with domed top profile
• Mounting Interface: Through-hole, right-angle orientation
• Electrical Compatibility: Forward voltage ratings and millicandela output within acceptable operating ranges for the application circuit
• Footprint Compatibility: Pin spacing and mechanical envelope must accommodate existing PCB layouts

The substitute part 5640200132F from Dialight meets these core substitution criteria. Both components share identical physical configuration (3-high, 3mm T-1 lens, right-angle through-hole mounting) and color arrangement (Green, Red, Yellow). Electrical parameters remain within compatible ranges for typical LED indicator circuit designs.

Engineering Selection Recommendations

The 5640200132F from Dialight is a direct functional substitute for the obsolete QLA764BHGY. Both components share identical mechanical and electrical interfaces, enabling drop-in replacement in existing PCB designs without layout modifications.

The Dialight 5640200132F offers the additional advantage of active product status and ROHS3 compliance, supporting long-term supply chain continuity and regulatory alignment with current environmental standards. The forward voltage ratings of the substitute are lower across all three LED colors (Green: 1.9V vs. 2.1V; Red: 1.7V vs. 2.1V; Yellow: 1.8V vs. 2.1V), which may reduce power consumption in the indicator circuit. The millicandela ratings are marginally higher (1.6mcd vs. 1.4mcd), providing improved luminous intensity.

Selection of the substitute part should be validated against the specific circuit design requirements, particularly regarding current-limiting resistor values and power supply voltage to ensure optimal LED performance and longevity.

Frequently Asked Questions (FAQ)

Q: Can the 5640200132F directly replace the QLA764BHGY without PCB modifications?

A: Yes. Both components feature identical 3mm T-1 lens geometry, round domed top profile, and right-angle through-hole mounting configuration. The pin spacing and mechanical envelope are compatible, enabling direct substitution without PCB layout changes.

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

A: The primary electrical difference is forward voltage. The QLA764BHGY operates at 2.1V across all three LED colors, while the 5640200132F operates at lower voltages: 1.9V (Green), 1.7V (Red), and 1.8V (Yellow). Circuit designers must adjust current-limiting resistor values accordingly to maintain proper LED current and brightness levels.

Q: Does the lower forward voltage of the substitute affect brightness?

A: The 5640200132F delivers slightly higher millicandela ratings (1.6mcd vs. 1.4mcd) despite lower forward voltage, indicating improved luminous efficiency. Actual perceived brightness depends on circuit current and application-specific viewing conditions.

Q: Is the 5640200132F suitable for new designs?

A: Yes. The 5640200132F is an active product with ROHS3 compliance, making it appropriate for new designs requiring long-term supply availability and regulatory compliance.

Q: What is the viewing angle difference?

A: The QLA764BHGY does not specify a viewing angle parameter. The 5640200132F specifies 60° viewing angle, indicating the angular range over which LED luminous intensity remains within acceptable levels. This specification does not affect mechanical compatibility.
