Key Parameters

Substitute Part Grouping Explanation

Substitution of the QLA764B3G is determined by the following critical parameters that must remain consistent:

• Configuration: 3 High (three LED elements in series)
• Color: Green (x 3)
• Lens Type: Diffused, Tinted
• Lens Style: Round with Domed Top
• Lens Size: 3mm, T-1
• Mounting Type: Through Hole, Right Angle

The WP934SA/3GD from Kingbright satisfies all these core mechanical and functional requirements. Variations in voltage rating, current, and brightness output are acceptable within typical circuit design tolerances for indicator applications, provided the substitute part maintains electrical compatibility with the host circuit design.

Parameter Comparison

Engineering Selection Recommendations

The WP934SA/3GD is the identified substitute for the obsolete QLA764B3G. Selection of this substitute is supported by the following factors:

• The WP934SA/3GD maintains active product status, ensuring long-term availability and supply chain continuity.
• The substitute achieves ROHS3 compliance, meeting current regulatory requirements for electronic components in regulated markets.
• Mechanical and functional compatibility is confirmed through identical configuration, color, lens type, lens style, lens size, and mounting type.
• The substitute operates at 2.2V with 20mA current and 22.5mcd brightness, representing higher performance characteristics suitable for indicator applications.

Frequently Asked Questions (FAQ)

Q: Can the WP934SA/3GD directly replace the QLA764B3G in existing designs?

A: The WP934SA/3GD is mechanically and functionally compatible with the QLA764B3G. Both components feature identical 3-high configuration, green color, 3mm T-1 through-hole right-angle mounting, and diffused tinted lens. Circuit design review is necessary to confirm electrical compatibility, as the substitute operates at 2.2V versus 2.1V and draws 20mA versus 10mA.

Q: What are the key differences between these parts?

A: The primary differences are voltage rating (2.1V vs. 2.2V), current consumption (10mA vs. 20mA), brightness output (6mcd vs. 22.5mcd), and product status (obsolete vs. active). The WP934SA/3GD also provides specified wavelength (568nm) and viewing angle (40°) data not available for the original part.

Q: Does the substitute meet current compliance standards?

A: The WP934SA/3GD is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The original QLA764B3G is RoHS non-compliant, making the substitute preferable for new designs and regulated applications.

Q: Are there packaging considerations for the substitute?

A: The WP934SA/3GD is supplied in tube packaging. Verify packaging compatibility with your assembly and handling processes.
