AA3020ACGCK Equivalent & Substitute Parts

Part Overview

The AA3020ACGCK is a green surface mount LED manufactured by Kingbright, designed for indication applications with a dominant wavelength of 570nm. This component features a rectangular lens with flat top configuration and delivers 60 millicandela brightness at 20mA test current. The part is classified as obsolete, necessitating identification of active equivalent components for new designs and ongoing production requirements. Substitute parts must maintain electrical compatibility while meeting current manufacturing and supply chain standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AA3020ACGCK is determined by the following critical parameters that must remain constant or compatible:

Electrical Compatibility Requirements:

• Forward voltage (Vf) of 2.1V nominal
• Test current of 20mA
• Dominant wavelength of 570nm (green spectrum)
• Surface mount configuration with 2-SMD, J-Lead package

Mechanical Compatibility Requirements:

• SMD mounting footprint compatibility
• Overall dimensions within acceptable tolerance for PCB layout

Regulatory & Compliance Requirements:

• ROHS3 compliance maintained
• REACH unaffected status

The AA3021CGSK qualifies as a direct substitute based on matching electrical parameters (2.1V forward voltage, 20mA test current, 570nm dominant wavelength) and identical package configuration. Differences in brightness rating, lens geometry, and viewing angle do not preclude substitution when the application requirements permit.

Parameter Comparison

Engineering Selection Recommendations

The AA3021CGSK is the qualified substitute for the obsolete AA3020ACGCK based on the following engineering criteria:

Electrical Equivalence: Both components operate at identical forward voltage (2.1V) and test current (20mA) with matching dominant wavelength (570nm), ensuring direct circuit compatibility without modification to current-limiting resistor calculations or power supply specifications.

Package Compatibility: Both parts utilize the 2-SMD, J-Lead configuration with identical footprint dimensions (2.70mm L x 2.00mm W), permitting direct PCB layout substitution without redesign.

Regulatory Compliance: The AA3021CGSK maintains ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements equivalent to the original part.

Product Status: The AA3021CGSK is classified as active with confirmed inventory availability (4288 pcs), ensuring supply chain continuity and long-term procurement viability compared to the obsolete AA3020ACGCK.

Packaging Format: The AA3021CGSK is supplied in Tape & Reel (TR) format, standard for high-volume production environments, whereas the original part packaging is not specified.

Frequently Asked Questions (FAQ)

Q: Can the AA3021CGSK be used as a direct replacement for the AA3020ACGCK without circuit modifications?

A: Yes. Both components share identical electrical specifications (2.1V forward voltage, 20mA test current, 570nm dominant wavelength) and package configuration (2-SMD, J-Lead). No changes to current-limiting resistors, power supply connections, or PCB layout are required.

Q: What are the differences between these two parts?

A: The AA3021CGSK differs in the following non-critical parameters: millicandela rating (80mcd vs. 60mcd), lens style (oval with flat top vs. rectangle with flat top), lens size (2.50mm x 1.50mm vs. 2.00mm x 1.40mm), viewing angle (125° vs. 90°), maximum height (1.50mm vs. 1.65mm), and moisture sensitivity level (MSL 3 vs. MSL 4). These differences do not affect electrical compatibility.

Q: Is the higher brightness rating of the AA3021CGSK a concern for existing designs?

A: The increased brightness (80mcd vs. 60mcd) is a performance enhancement. Applications designed for 60mcd operation will function correctly with the higher-brightness substitute. If brightness reduction is required, circuit-level current adjustment through resistor modification is possible.

Q: Are there any compliance or certification differences?

A: Both parts maintain ROHS3 compliance and REACH unaffected status. Regulatory and environmental certifications are equivalent.

Q: What is the impact of the different viewing angles (90° vs. 125°)?

A: The AA3021CGSK provides a wider viewing angle (125° vs. 90°), resulting in improved visibility across a broader range of observation positions. This is generally beneficial for indication applications and does not create compatibility issues.

Q: Can the AA3021CGSK be used in applications originally designed for the AA3020ACGCK?

A: Yes. Electrical and mechanical compatibility is maintained. The substitute part is suitable for all applications where the original part was specified, provided the application does not have specific constraints on brightness, lens geometry, or viewing angle that would be negatively affected by the differences noted in the parameter comparison table.
