AA3020ASECK Equivalent & Substitute Parts

Part Overview

The AA3020ASECK is an orange surface-mount LED indicator manufactured by Kingbright, featuring a 601nm dominant wavelength and 250mcd luminous intensity. This component is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. The part operates at 2.1V forward voltage with a 20mA test current and is housed in a 2-SMD J-Lead package with rectangular flat-top lens geometry.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AA3020ASECK is determined by the following critical parameters that must remain constant or compatible:

Fixed Parameters (Must Match):

• Dominant wavelength: 601nm
• Peak wavelength: 610nm
• Forward voltage: 2.1V
• Test current: 20mA
• Mounting type: Surface Mount
• Package type: 2-SMD, J-Lead
• Physical dimensions: 2.70mm L x 2.00mm W
• Color: Orange
• RoHS compliance: ROHS3 Compliant

Variable Parameters (Allowable Variation):

• Millicandela rating (brightness)
• Lens style and size
• Viewing angle
• Height
• Moisture sensitivity level
• Product status (active preferred over obsolete)
• Packaging format (tube vs. tape & reel)

The AA3021SESK qualifies as a direct substitute based on matching all fixed parameters while offering improved specifications in variable parameters.

Parameter Comparison

Engineering Selection Recommendations

The AA3021SESK is the direct substitute for the obsolete AA3020ASECK. Both components share identical electrical characteristics (2.1V forward voltage, 20mA test current, 601nm dominant wavelength) and mechanical compatibility (2-SMD J-Lead package, 2.70mm x 2.00mm footprint, surface mount configuration).

The AA3021SESK offers the following advantages:

• Active Product Status: The AA3021SESK maintains active manufacturing status, ensuring long-term availability and supply chain continuity.
• Enhanced Specifications: Increased luminous intensity (300mcd vs. 250mcd) and wider viewing angle (125° vs. 90°) provide improved optical performance.
• Improved Reliability: Lower moisture sensitivity level (MSL 3 vs. MSL 4) indicates superior moisture resistance during storage and handling.
• Reduced Height: Maximum height of 1.50mm versus 1.65mm provides better clearance in space-constrained applications.
• Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status.

The AA3021SESK is suitable for direct replacement in all applications where the AA3020ASECK was previously specified, with no circuit modifications required.

Frequently Asked Questions (FAQ)

Q: Can the AA3021SESK be used as a direct drop-in replacement for the AA3020ASECK?

A: Yes. Both components share identical forward voltage (2.1V), test current (20mA), dominant wavelength (601nm), package type (2-SMD J-Lead), and physical footprint (2.70mm x 2.00mm). No circuit redesign is necessary.

Q: What are the differences between these two parts?

A: The AA3021SESK provides higher luminous intensity (300mcd vs. 250mcd), wider viewing angle (125° vs. 90°), lower profile height (1.50mm vs. 1.65mm), and improved moisture resistance (MSL 3 vs. MSL 4). The lens geometry differs from rectangular to oval configuration.

Q: Why is the AA3020ASECK obsolete?

A: The AA3020ASECK is classified as obsolete by the manufacturer. The AA3021SESK represents the active equivalent in Kingbright's current product portfolio.

Q: Does the different lens shape affect compatibility?

A: The lens shape difference (rectangular vs. oval) does not affect electrical compatibility or PCB footprint. Optical characteristics such as viewing angle and light distribution will differ slightly due to the lens geometry change.

Q: What is the significance of the MSL rating difference?

A: MSL 3 (168 hours) provides longer moisture protection than MSL 4 (72 hours). The AA3021SESK can tolerate extended exposure to humid conditions before soldering, reducing risk of moisture-related failures during manufacturing.

Q: Are there packaging format differences?

A: The AA3020ASECK is supplied in tube packaging, while the AA3021SESK is supplied in Tape & Reel (TR) format. Both formats contain identical components; packaging selection depends on production volume and assembly equipment compatibility.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the AA3020ASECK and AA3021SESK are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory requirements.
