QBLP679-RGB LED RGB Diffused 6PLCC SMD Equivalent & Substitute Parts

Part Overview

The QBLP679-RGB is an active RGB LED indicator manufactured by QT Brightek (QTB), configured as an independent three-color light source in a 6-SMD J-Lead surface mount package. This component integrates red (620nm), green (525nm), and blue (470nm) discrete LED elements with diffused white lens optics and 120° viewing angle. The part is ROHS3 compliant and currently in active production status with 1038 units in stock.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance are maintained across the same product series and package specification.

Substitute Part Grouping Explanation

Substitution eligibility for the QBLP679-RGB is determined by strict parametric equivalence within the QBLP679 series. The following criteria establish substitution validity:

Electrical Equivalence Requirements:

• Identical wavelength specifications: 620nm red, 525nm green, 470nm blue
• Matching forward voltage ratings: 2V red, 3.3V green, 3.2V blue
• Identical test current: 20mA per color channel
• Equivalent luminous intensity: 630mcd red, 1500mcd green, 285mcd blue

Mechanical Compatibility Requirements:

• Identical package type: 6-SMD J-Lead (6-PLCC)
• Matching lens configuration: Round with flat top, 4.00mm diameter, diffused white
• Identical physical footprint: 5.00mm L x 5.00mm W
• Matching maximum height: 1.60mm
• Same mounting technology: Surface mount

Regulatory and Environmental Compliance:

• ROHS3 compliance maintained
• REACH unaffected status maintained
• Identical MSL rating: 3 (168 Hours)
• Same packaging format: Tape & Reel

Substitute parts must originate from the same manufacturer (QT Brightek) and maintain active product status to ensure supply chain continuity and consistent manufacturing quality.
