Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AA3528AEC are qualified based on the following criteria:

Mandatory Matching Parameters:

• Package / Case: 2-PLCC
• Mounting Type: Surface Mount
• Voltage - Forward (Vf): 2V
• Current - Test: 20mA
• Color: Red
• Lens Transparency: Clear
• Viewing Angle: 120°
• Lens Size: 2.40mm Dia
• Physical Dimensions: 3.20mm L x 2.80mm W
• Height (Max): 2.10mm
• RoHS Status: ROHS3 Compliant

Allowable Variation Parameters:

• Millicandela Rating: Brightness variations within the red LED indicator category
• Wavelength - Dominant: Red spectrum variations (617nm to 625nm range)
• Wavelength - Peak: Red spectrum peak variations
• Moisture Sensitivity Level: MSL 3 or MSL 4 acceptable
• Supplier Device Package designation: Variations in supplier nomenclature for equivalent 2-PLCC packages

All three substitute parts meet these criteria and are functionally interchangeable in applications requiring red LED indication with 2V operation and 20mA test current.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and full ROHS3 compliance, ensuring regulatory alignment with current manufacturing standards. Selection between AA3528AEC and its substitutes depends on brightness requirements and supply availability:

AA3528AEC provides 30mcd brightness at 625nm dominant wavelength with MSL 4 rating. This part is suitable for applications requiring maximum brightness output within the 2-PLCC red LED category.

AA3528EC operates at 12mcd brightness with 617nm dominant wavelength and MSL 4 rating. This substitute is appropriate for applications where lower brightness is acceptable and cost optimization is a consideration.

AA3528ES delivers 12mcd brightness at 625nm dominant wavelength with improved MSL 3 rating (168 hours). This substitute offers enhanced moisture protection compared to the main part and maintains identical wavelength characteristics.

SML-LX2832IC-TR from Lumex provides 25mcd brightness with 635nm peak wavelength and MSL 3 rating. This cross-manufacturer substitute is suitable for applications where Lumex component qualification is required or where alternative sourcing is necessary.

All four parts are mechanically and electrically compatible for direct substitution in 2-PLCC surface-mount applications operating at 2V with 20mA test current.

Frequently Asked Questions (FAQ)

Q: Can AA3528EC replace AA3528AEC in all applications?

A: AA3528EC is mechanically and electrically compatible as a direct substitute. The primary difference is brightness: AA3528EC provides 12mcd compared to AA3528AEC's 30mcd. Substitution is valid only if the application does not require the higher brightness output of the main part.

Q: What is the difference between AA3528ES and AA3528AEC?

A: Both parts operate at identical electrical parameters (2V, 20mA) and share the same 625nm dominant wavelength. The key differences are: AA3528ES provides 12mcd brightness versus 30mcd for AA3528AEC, and AA3528ES has MSL 3 rating (168 hours) compared to MSL 4 (72 hours) for AA3528AEC. AA3528ES offers superior moisture protection.

Q: Is SML-LX2832IC-TR from Lumex compatible with Kingbright AA3528 parts?

A: Yes, SML-LX2832IC-TR is mechanically and electrically compatible. It maintains the same 2-PLCC package, 2V forward voltage, 20mA test current, and 120° viewing angle. The brightness is 25mcd at 635nm peak wavelength. This part is suitable for applications where cross-manufacturer sourcing is required.

Q: What does MSL rating mean for these LED parts?

A: Moisture Sensitivity Level (MSL) indicates the maximum time a component can be exposed to moisture at specified temperature and humidity before soldering. MSL 3 allows 168 hours of exposure, while MSL 4 allows 72 hours. Higher MSL numbers indicate shorter safe storage periods in humid conditions.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all four parts (AA3528AEC, AA3528EC, AA3528ES, and SML-LX2832IC-TR) are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Can I use AA3528AEC in place of AA3528ES?

A: Yes, AA3528AEC is a direct substitute for AA3528ES. Both share identical electrical characteristics and wavelength specifications. AA3528AEC provides higher brightness (30mcd versus 12mcd) and has MSL 4 rating instead of MSL 3.

Q: What is the significance of wavelength differences between these parts?

A: All parts are red LEDs within acceptable red spectrum range. AA3528AEC and AA3528ES both have 625nm dominant wavelength. AA3528EC has 617nm dominant wavelength. SML-LX2832IC-TR has 635nm peak wavelength. These variations are within the red LED category and do not affect functional compatibility in indication applications.
