AA3020ASGC Equivalent & Substitute Parts

Part Overview

The AA3020ASGC is a green surface mount LED manufactured by Kingbright, designed for indication applications with a dominant wavelength of 568nm. This component features a rectangular lens with flat top configuration and delivers 30mcd luminous intensity at 20mA test current. The part is classified as obsolete, necessitating identification of active substitute components that maintain electrical and mechanical compatibility for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AA3020ASGC is determined by the following critical parameters that must remain constant or compatible:

Electrical Compatibility Requirements:

• Forward voltage (Vf) of 2.2V
• Test current of 20mA
• Dominant wavelength of 568nm (green spectrum)

Mechanical Compatibility Requirements:

• Surface mount mounting type
• 2-SMD, J-Lead package configuration
• Physical dimensions of 2.70mm L x 2.00mm W
• Maximum height not exceeding 1.65mm

Regulatory Compliance:

• ROHS3 compliance
• REACH unaffected status

The AA3021SGS qualifies as a substitute based on matching all electrical parameters and package specifications. Variations in millicandela rating, lens geometry, viewing angle, and height fall within acceptable substitution parameters for indication applications where the primary function is signal presence rather than precise luminous intensity matching.

Parameter Comparison

Engineering Selection Recommendations

The AA3021SGS is suitable as a substitute for the AA3020ASGC based on the following engineering criteria:

Electrical Equivalence: Both components operate at identical forward voltage (2.2V) and test current (20mA) with matching dominant wavelength (568nm), ensuring direct circuit compatibility without modification to drive circuitry or current-limiting resistor calculations.

Mechanical Fit: The AA3021SGS maintains identical footprint dimensions (2.70mm L x 2.00mm W) and package configuration (2-SMD, J-Lead), confirming PCB layout compatibility. The reduced maximum height (1.50mm versus 1.65mm) presents no clearance issues.

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements for equivalent applications.

Product Status Advantage: The AA3021SGS holds active product status with 2961 units in stock, compared to the obsolete AA3020ASGC status, ensuring long-term availability and supply chain continuity.

Luminous Intensity Consideration: The AA3021SGS delivers 20mcd compared to the main part's 30mcd. This 33% reduction in luminous intensity is acceptable for indication applications where the primary function is signal presence confirmation rather than high-brightness visibility requirements.

Frequently Asked Questions (FAQ)

Q: Can the AA3021SGS replace the AA3020ASGC in existing designs without PCB modification?

A: Yes. Both components share identical footprint dimensions (2.70mm L x 2.00mm W) and 2-SMD, J-Lead package configuration. No PCB layout changes are required. The AA3021SGS's reduced height (1.50mm) presents no clearance conflicts.

Q: Will the 10mcd difference in luminous intensity affect circuit performance?

A: The AA3021SGS provides 20mcd versus the AA3020ASGC's 30mcd. For indication applications, this reduction is acceptable. If specific brightness requirements exist, circuit-level adjustments to forward current (within the 20mA test specification) can compensate for luminous intensity differences.

Q: Are the electrical parameters identical between these components?

A: Yes. Both components operate at 2.2V forward voltage and 20mA test current with matching 568nm dominant wavelength. No drive circuit modifications are necessary.

Q: What is the significance of the different lens geometries?

A: The AA3020ASGC features a rectangular lens with 90° viewing angle, while the AA3021SGS has an oval lens with 125° viewing angle. The wider viewing angle of the substitute may improve visibility from off-axis positions but does not affect electrical compatibility or circuit function.

Q: Why is the AA3021SGS recommended despite being obsolete status?

A: The AA3020ASGC is classified as obsolete with limited inventory (1040 units). The AA3021SGS maintains active product status with significantly higher stock availability (2961 units), ensuring supply chain continuity and long-term component availability for production and maintenance applications.

Q: Are both components RoHS3 compliant?

A: Yes. Both the AA3020ASGC and AA3021SGS are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for equivalent applications.
