Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VAOS-5050RGB136-ET is determined by the following critical parameters:

Primary Compatibility Criteria:

• RGB color configuration with independent red, green, and blue channels
• 6-SMD J-Lead package format
• 5050 form factor (5.00mm L x 5.00mm W)
• Surface mount mounting type
• Maximum height of 1.60mm
• 120° viewing angle
• Forward voltage compatibility within acceptable operating ranges (Red: 2.0-2.1V, Green: 3.2-3.4V, Blue: 3.2-3.4V)
• Test current of 20mA per color channel
• Wavelength ranges: Red 620-630nm, Green 525-530nm, Blue 468-470nm

Regulatory Compliance Requirements:

• ROHS3 compliance
• REACH unaffected status
• EAR99 export classification

The QBLP679E-RGB from QT Brightek (QTB) meets all primary compatibility criteria and regulatory requirements, establishing it as a direct functional equivalent despite differences in lens transparency and millicandela ratings.

Parameter Comparison

Engineering Selection Recommendations

The QBLP679E-RGB qualifies as a direct substitute for the obsolete VAOS-5050RGB136-ET based on electrical and mechanical parameter alignment. Both components maintain identical package geometry, mounting configuration, and test current specifications. Forward voltage parameters are within 0.05V tolerance across all color channels, ensuring compatibility with existing circuit designs without modification.

The substitute part carries active product status with full ROHS3 and REACH compliance, providing supply chain continuity and regulatory assurance. The QBLP679E-RGB is available in Tape & Reel packaging format, supporting automated assembly processes typical of production environments.

Differences in lens transparency (clear versus diffused) and millicandela ratings represent optical performance variations rather than compatibility barriers. The diffused lens of the substitute part produces wider light distribution characteristics, while the higher green channel millicandela rating (1500mcd versus 1068mcd) indicates increased luminous intensity. These differences require evaluation against specific application requirements for color uniformity, viewing distance, and brightness specifications.

The elevated moisture sensitivity level (MSL 3 versus MSL 1) for the substitute part necessitates adherence to standard moisture control protocols during storage and assembly, consistent with industry practices for components in this classification.

Frequently Asked Questions (FAQ)

Q: Can the QBLP679E-RGB directly replace the VAOS-5050RGB136-ET without PCB modifications?

A: Yes. Both components share identical 6-SMD J-Lead package geometry, 5.00mm x 5.00mm footprint, and 1.60mm maximum height. PCB land patterns and solder pad configurations are compatible. Forward voltage parameters differ by less than 0.05V per channel, remaining within standard circuit tolerance ranges.

Q: What is the primary difference between these two RGB LEDs?

A: The VAOS-5050RGB136-ET features a clear lens with discrete optical output, while the QBLP679E-RGB incorporates a diffused white lens producing wider light distribution. The substitute part delivers higher green channel intensity (1500mcd versus 1068mcd) and lower blue channel intensity (285mcd versus 338mcd).

Q: Are there compliance or regulatory differences between the main part and substitute?

A: Both components are ROHS3 compliant and REACH unaffected. The substitute part carries MSL 3 rating (168-hour moisture sensitivity) compared to MSL 1 (unlimited) for the main part. Standard moisture control during storage and assembly is required for the substitute component.

Q: What packaging formats are available for each part?

A: The VAOS-5050RGB136-ET is supplied in bulk packaging. The QBLP679E-RGB is available in Tape & Reel (TR) format, supporting automated pick-and-place assembly operations.

Q: How do the wavelength specifications compare?

A: Dominant wavelengths differ by 6nm for red (626nm versus 620nm), 5nm for green (530nm versus 525nm), and 1nm for blue (469nm versus 470nm). These variations fall within standard LED manufacturing tolerances and do not affect color perception in typical applications.

Q: Is the substitute part suitable for high-brightness applications?

A: The QBLP679E-RGB delivers higher green channel output (1500mcd) but lower blue channel output (285mcd) compared to the main part. Application suitability depends on specific brightness and color balance requirements. The diffused lens distributes light over a wider area, reducing peak intensity at the optical axis.

Q: What is the inventory status for each part?

A: The VAOS-5050RGB136-ET has 970 pieces in stock as new original inventory. The QBLP679E-RGB has 4367 pieces in stock as new original inventory, providing superior supply availability.
