AA3528APBC/A Equivalent & Substitute Parts

Part Overview

The AA3528APBC/A is a blue 470nm LED indication component manufactured by Kingbright in a 2-PLCC surface mount package. This discrete LED operates at 3.2V forward voltage with a 60mcd brightness rating and 120° viewing angle. The component is classified as obsolete, making substitute parts necessary for ongoing production and maintenance applications. Equivalent alternatives maintain the same package form factor, mounting type, and core optical characteristics while offering improved availability and active product status.

Substitute Part Grouping Explanation

Substitute parts for the AA3528APBC/A are classified based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Package / Case: 2-PLCC (mandatory match)
• Mounting Type: Surface Mount (mandatory match)
• Color: Blue (mandatory match)
• Lens Size: 2.40mm Dia (mandatory match)
• Physical Dimensions: 3.20mm L x 2.80mm W (mandatory match)
• Height (Max): 2.10mm (mandatory match)

Secondary Compatibility Parameters:

• Voltage - Forward (Vf): 3.1V to 3.3V range (acceptable tolerance)
• Current - Test: 10mA to 20mA (acceptable range)
• Millicandela Rating: 60mcd to 200mcd (brightness variation acceptable)
• Viewing Angle: 115° to 120° (acceptable range)
• Wavelength - Dominant: 465nm to 470nm (blue spectrum range)
• RoHS Status: ROHS3 Compliant (mandatory match)

Substitutes are grouped into two categories: direct Kingbright alternatives with active product status, and parametric equivalents from alternative manufacturers meeting all mechanical and electrical specifications.

Engineering Selection Recommendations

AA3528QBC/D (Kingbright - Primary Substitute)

The AA3528QBC/D is the recommended primary substitute for the obsolete AA3528APBC/A. Both components are manufactured by Kingbright and share identical mechanical specifications, package form factor, and mounting characteristics. The AA3528QBC/D maintains active product status with 1063 units in stock. Forward voltage increases from 3.2V to 3.3V, representing a 3% increase within acceptable circuit design tolerance. Brightness increases to 200mcd, providing enhanced luminous intensity for indication applications. All compliance certifications match the original component, including ROHS3 compliance and REACH unaffected status.

AA3528QBS/D (Kingbright - Secondary Substitute)

The AA3528QBS/D serves as a secondary Kingbright alternative with the highest inventory availability at 8300 units. This component maintains identical mechanical dimensions and package specifications. Wavelength shifts to 465nm (dominant) with 150mcd brightness. Forward voltage matches the AA3528QBC/D at 3.3V. Moisture sensitivity improves to MSL 3 (168 Hours) compared to MSL 4 on the original component. Packaging is supplied in Tape & Reel format, suitable for automated assembly processes.

VCEB1104LS-TR (Stanley Electric Co - Parametric Equivalent)

The VCEB1104LS-TR from Stanley Electric Co provides a parametric equivalent from an alternative manufacturer. All mechanical specifications and package dimensions match the original component exactly. Forward voltage is 3.1V, representing the closest match to the original 3.2V specification. Brightness rating matches at 60mcd. Viewing angle is 115°, within acceptable tolerance of the original 120°. Moisture sensitivity is superior at MSL 2A (4 Weeks). This component is supplied in Tape & Reel packaging with 767 units in stock. All compliance certifications are met.

Frequently Asked Questions (FAQ)

Q: Can AA3528QBC/D be used as a direct replacement for AA3528APBC/A?

A: Yes. Both components share identical package specifications (2-PLCC), mounting type (Surface Mount), physical dimensions (3.20mm L x 2.80mm W x 2.10mm H), and lens size (2.40mm Dia). Forward voltage increases from 3.2V to 3.3V, which is within standard circuit design tolerance. Brightness increases from 60mcd to 200mcd. All compliance certifications match.

Q: What is the difference between AA3528QBC/D and AA3528QBS/D?

A: Both are Kingbright alternatives with identical mechanical specifications. AA3528QBC/D has 200mcd brightness at 470nm wavelength. AA3528QBS/D has 150mcd brightness at 465nm wavelength. AA3528QBS/D offers improved moisture sensitivity (MSL 3 vs MSL 4) and higher inventory availability (8300 units vs 1063 units). Both operate at 3.3V forward voltage.

Q: Why is VCEB1104LS-TR from a different manufacturer?

A: VCEB1104LS-TR is a parametric equivalent from Stanley Electric Co that meets all mechanical and electrical specifications of the original component. It provides an alternative sourcing option when Kingbright alternatives are unavailable. Forward voltage (3.1V) is closest to the original specification (3.2V). Brightness matches at 60mcd. All package dimensions and compliance certifications are identical.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (AA3528QBC/D, AA3528QBS/D, and VCEB1104LS-TR) are ROHS3 compliant, matching the original AA3528APBC/A specification.

Q: What is the impact of forward voltage differences?

A: Forward voltage variations from 3.1V to 3.3V are within acceptable tolerance for LED indication circuits. The original component operates at 3.2V. AA3528QBC/D and AA3528QBS/D operate at 3.3V (0.1V increase). VCEB1104LS-TR operates at 3.1V (0.1V decrease). Circuit designs must accommodate these variations through appropriate current-limiting resistor selection.

Q: Which substitute offers the best moisture protection?

A: VCEB1104LS-TR offers the best moisture sensitivity rating at MSL 2A (4 Weeks), compared to MSL 4 (72 Hours) for AA3528APBC/A and AA3528QBC/D, and MSL 3 (168 Hours) for AA3528QBS/D.

Q: Are tape and reel packaged parts compatible with bulk packaged designs?

A: Yes. Tape and reel packaging (AA3528QBS/D and VCEB1104LS-TR) contains the same components as bulk packaging. Tape and reel format is optimized for automated assembly processes. Component specifications and performance are identical regardless of packaging format.
