Parameter Comparison

Engineering Selection Recommendations

The APDA1806VBC/D is the direct substitute for the obsolete APDA1806QBC/D. Both components share identical electrical specifications (3.3V forward voltage, 20mA test current), mechanical dimensions (1.80mm x 1.50mm x 0.70mm), and regulatory compliance (ROHS3, MSL 3).

The APDA1806VBC/D carries Active product status, ensuring ongoing availability and supply chain support. This part is manufactured by the same supplier (Kingbright) and maintains the same base product number (APDA1806), confirming design continuity.

The APDA1806VBC/D exhibits higher luminous intensity (800mcd versus 320mcd) and operates at a slightly longer dominant wavelength (470nm versus 465nm). These differences remain within the blue LED spectrum and do not affect electrical or mechanical compatibility in standard indication applications.

Both components maintain identical ROHS3 compliance and MSL ratings, supporting equivalent handling and storage requirements in manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can the APDA1806VBC/D replace the APDA1806QBC/D in existing designs?

A: Yes. Both components share identical forward voltage (3.3V), test current (20mA), mounting type (surface mount, right angle), package configuration (2-SMD, No Lead), and physical dimensions (1.80mm L x 1.50mm W x 0.70mm H). Electrical and mechanical compatibility is confirmed.

Q: What is the difference in luminous intensity between these parts?

A: The APDA1806QBC/D operates at 320mcd, while the APDA1806VBC/D operates at 800mcd. The substitute part provides higher brightness output. Applications requiring the original brightness specification should evaluate this difference against circuit design parameters.

Q: Are the wavelength specifications different?

A: Yes. The APDA1806QBC/D has a dominant wavelength of 465nm (peak 460nm), while the APDA1806VBC/D has a dominant wavelength of 470nm (peak 465nm). Both operate within the blue LED spectrum. Applications with specific wavelength requirements should confirm compatibility with system specifications.

Q: What is the packaging difference?

A: The APDA1806QBC/D is supplied in Cut Tape (CT) & Digi-Reel® packaging, while the APDA1806VBC/D is supplied in Tape & Reel (TR) packaging. Both are surface mount compatible. Packaging selection depends on production volume and assembly equipment requirements.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the APDA1806QBC/D and APDA1806VBC/D are ROHS3 Compliant with MSL Rating 3 (168 Hours), confirming equivalent environmental and regulatory compliance.

Q: Why is the APDA1806QBC/D listed as Obsolete?

A: The APDA1806QBC/D carries Obsolete product status. The APDA1806VBC/D is the Active equivalent, ensuring continued supply availability and manufacturing support.
