Key Parameters

Substitute Part Grouping Explanation

Substitution of the ALMD-CB3D-RT002 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility:

• Wavelength - Dominant: 470nm (blue spectrum)
• Wavelength - Peak: 464nm
• Voltage - Forward (Vf) (Typ): 3.2V
• Current - Test: 20mA
• Viewing Angle: 30°

Mechanical Compatibility:

• Mounting Type: Surface Mount
• Package / Case: 4-SMD, Gull Wing
• Lens Style: Round with Domed Top
• Size / Dimension: 4.20mm L x 4.20mm W
• Height (Max): 7.00mm

Regulatory & Environmental:

• REACH Status: REACH Unaffected
• ECCN: EAR99
• Moisture Sensitivity Level (MSL): 2A (4 Weeks)

The substitute part ALMD-CB3D-SU002 maintains full equivalence across all critical electrical, mechanical, and regulatory parameters, with the primary distinction being active product status and increased brightness rating (3050mcd vs. 2350mcd).

Parameter Comparison

Engineering Selection Recommendations

The ALMD-CB3D-SU002 is the direct equivalent substitute for the obsolete ALMD-CB3D-RT002. Both components are manufactured by Broadcom Limited and share identical electrical specifications, mechanical dimensions, and regulatory compliance status. The substitute part maintains active product status, ensuring continued availability and supply chain support.

The ALMD-CB3D-SU002 exhibits a higher millicandela rating (3050mcd vs. 2350mcd) while maintaining all other parameters. This increased brightness is a performance enhancement that does not compromise compatibility with existing circuit designs, as the forward voltage, test current, and viewing angle remain unchanged.

Both components comply with REACH regulations and carry EAR99 export classification. Moisture sensitivity level is identical at 2A (4 Weeks), requiring equivalent handling and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can ALMD-CB3D-SU002 be used as a direct replacement for ALMD-CB3D-RT002?

A: Yes. Both components share identical electrical specifications (3.2V forward voltage, 20mA test current, 470nm dominant wavelength, 30° viewing angle), mechanical dimensions (4.20mm L x 4.20mm W, 7.00mm max height), and package configuration (4-SMD, Gull Wing). The substitute part is fully compatible with existing PCB layouts and circuit designs.

Q: What is the difference between these two parts?

A: The primary differences are product status and brightness rating. ALMD-CB3D-RT002 is obsolete with 2350mcd brightness, while ALMD-CB3D-SU002 is active with 3050mcd brightness. All other electrical, mechanical, and regulatory parameters are identical.

Q: Are there any packaging differences?

A: The main part is supplied in standard packaging, while the substitute is available in Cut Tape (CT) and Digi-Reel® packaging options. Both use the same 4-SMD, Gull Wing package configuration with identical physical dimensions.

Q: Do these parts have the same regulatory compliance?

A: Yes. Both components are REACH Unaffected, carry EAR99 export classification, and share identical Moisture Sensitivity Level (2A, 4 Weeks).

Q: Will the higher brightness of ALMD-CB3D-SU002 affect circuit operation?

A: No. The substitute part maintains identical forward voltage (3.2V) and test current (20mA) specifications. The increased brightness rating does not alter electrical behavior in existing circuit designs.
