AA3528ACGCK Green LED Equivalent & Substitute Parts

Part Overview

The AA3528ACGCK is a green surface-mount LED indicator manufactured by Kingbright, featuring a 570nm dominant wavelength and 60mcd luminous intensity. This component is classified as obsolete product status. Locating equivalent substitute parts is necessary due to discontinued availability of the original part number. Substitute components must maintain compatibility across forward voltage, package configuration, mounting type, and optical characteristics to ensure direct replacement in existing designs.

Parameter Comparison

Engineering Selection Recommendations

AA3528CGSK (Kingbright): This part is the primary substitute for AA3528ACGCK. Both components are manufactured by Kingbright and share identical electrical and mechanical specifications. AA3528CGSK carries active product status, ensuring continued availability and supply chain stability. The higher millicandela rating (100mcd versus 60mcd) provides increased luminous intensity while maintaining all other parameters. Moisture sensitivity level is improved (MSL 3 versus MSL 4), offering better reliability in humid environments. This part is supplied in Tape & Reel packaging, suitable for automated assembly processes.

SML-LX2832GC-TR (Lumex Opto/Components Inc.): This part qualifies as a secondary substitute. All critical electrical parameters (2.1V forward voltage, 20mA test current) and mechanical specifications (2-PLCC package, 2.40mm lens, 120° viewing angle) are identical. The peak wavelength of 565nm falls within acceptable green spectrum range. The lower millicandela rating (25mcd) represents a significant reduction in luminous intensity compared to the original 60mcd specification. This part is suitable only for applications where reduced brightness is acceptable. Active product status and improved moisture sensitivity (MSL 3) support long-term availability.

Both substitute parts maintain full RoHS3 compliance and REACH unaffected status, meeting regulatory requirements for the original component.

Frequently Asked Questions (FAQ)

Q: Can AA3528CGSK directly replace AA3528ACGCK in all applications?

A: Yes. AA3528CGSK maintains identical forward voltage (2.1V), test current (20mA), package type (2-PLCC), lens configuration, and physical dimensions. The higher luminous intensity (100mcd versus 60mcd) is a performance enhancement that does not compromise compatibility. Both parts are RoHS3 compliant.

Q: What is the key difference between AA3528CGSK and SML-LX2832GC-TR?

A: Both parts share identical electrical and mechanical specifications. The primary difference is luminous intensity: AA3528CGSK provides 100mcd while SML-LX2832GC-TR provides 25mcd. Additionally, peak wavelength differs slightly (574nm versus 565nm), both within green spectrum. Manufacturer differs (Kingbright versus Lumex).

Q: Is SML-LX2832GC-TR suitable as a direct replacement?

A: SML-LX2832GC-TR is mechanically and electrically compatible but delivers significantly lower brightness (25mcd versus 60mcd original specification). Use this part only in applications where reduced luminous intensity is acceptable. All other parameters including forward voltage, package, and mounting type are identical.

Q: What is the impact of different millicandela ratings on circuit design?

A: Millicandela rating affects perceived brightness only. It does not alter electrical requirements (voltage, current) or physical compatibility. Circuit designs using current-limiting resistors for the 2.1V forward voltage and 20mA test current remain valid across all three parts.

Q: Are there packaging differences between these parts?

A: AA3528ACGCK is supplied in bulk packaging. AA3528CGSK and SML-LX2832GC-TR are supplied in Tape & Reel (TR) format, optimized for automated pick-and-place assembly. Tape & Reel packaging does not affect component specifications or performance.

Q: What does MSL rating mean for these components?

A: Moisture Sensitivity Level (MSL) indicates how long a component can be exposed to moisture before soldering. AA3528ACGCK has MSL 4 (72 hours maximum). AA3528CGSK and SML-LX2832GC-TR have MSL 3 (168 hours maximum), providing extended shelf life and greater tolerance for storage in humid conditions.

Q: Are all three parts RoHS3 compliant?

A: Yes. AA3528ACGCK, AA3528CGSK, and SML-LX2832GC-TR are all ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements.
