Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AA3020AEC is determined by the following critical parameters:

Mandatory Matching Criteria:

• Manufacturer: Kingbright
• Color: Red
• Voltage - Forward (Vf): 2V
• Current - Test: 20mA
• Mounting Type: Surface Mount
• Package / Case: 2-SMD, J-Lead
• RoHS Status: ROHS3 Compliant

Allowable Variation Parameters:

• Wavelength - Dominant: Within red spectrum (617nm to 625nm acceptable)
• Millicandela Rating: Minimum 18mcd (slight reduction acceptable for equivalent function)
• Lens Size: Minor dimensional variations permitted within SMD constraints
• Viewing Angle: Variation acceptable based on application requirements
• Product Status: Active status preferred for ongoing availability

The AA3021ES meets all mandatory matching criteria and operates within allowable variation ranges for wavelength and brightness characteristics.

Parameter Comparison

Engineering Selection Recommendations

The AA3021ES is a direct substitute for the AA3020AEC based on electrical and mechanical compatibility. Both components share identical forward voltage (2V), test current (20mA), and package configuration (2-SMD, J-Lead).

Compliance Status: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent component selection.

Product Availability: The AA3021ES holds active product status with substantial inventory availability (22,818 pcs), whereas the AA3020AEC is obsolete. This availability differential supports transition to the AA3021ES for ongoing production and supply chain continuity.

Physical Considerations: The AA3021ES features a lower maximum height (1.50mm versus 1.65mm) and improved moisture sensitivity rating (MSL 3 versus MSL 4), providing enhanced reliability characteristics. Lens geometry differs (oval versus rectangular), with slightly larger dimensions (2.50mm x 1.50mm versus 2.00mm x 1.40mm). These dimensional changes require PCB layout verification to confirm mechanical fit within existing designs.

Optical Characteristics: The AA3021ES operates at 617nm dominant wavelength compared to 625nm for the AA3020AEC, representing an 8nm shift within the red spectrum. Brightness output is 18mcd versus 20mcd, a 10% reduction. Viewing angle increases from 90° to 125°. These optical variations are acceptable for indication applications where precise wavelength matching is not critical.

Frequently Asked Questions (FAQ)

Q: Can the AA3021ES directly replace the AA3020AEC without design modifications?

A: Electrical compatibility is confirmed. Mechanical fit requires verification due to lens size differences (2.50mm x 1.50mm versus 2.00mm x 1.40mm) and lens geometry change (oval versus rectangular). PCB layout and mechanical clearance must be assessed before implementation.

Q: What is the significance of the wavelength difference between 625nm and 617nm?

A: Both wavelengths fall within the red spectrum. The 8nm difference is not perceptible to human vision in indication applications. Selection depends on specific application requirements for color matching or spectral response characteristics.

Q: Does the 2mcd brightness reduction affect functionality?

A: The AA3021ES provides 18mcd versus 20mcd for the AA3020AEC, representing a 10% reduction. For indication applications, this reduction is typically acceptable. Applications requiring specific brightness thresholds must evaluate whether 18mcd meets minimum visibility requirements.

Q: What does the improved MSL rating (3 versus 4) mean?

A: MSL 3 allows 168 hours of moisture exposure before reflow, compared to 72 hours for MSL 4. The AA3021ES provides extended shelf life and greater tolerance for storage conditions prior to assembly.

Q: Are there packaging differences between these parts?

A: The AA3020AEC is supplied in standard packaging, while the AA3021ES is supplied in Tape & Reel (TR) format. TR packaging is standard for high-volume production and offers handling efficiency benefits.

Q: Why is the AA3020AEC obsolete?

A: Product obsolescence reflects manufacturer discontinuation decisions. The AA3021ES represents the active equivalent within Kingbright's current product portfolio, ensuring continued availability and support.
