Substitute Part Grouping Explanation

Substitution eligibility for the ALMD-CB3D-STC02 is determined by strict equivalence across the following critical parameters:

• Wavelength - Dominant: 470nm (blue spectrum)
• Wavelength - Peak: 464nm
• Voltage - Forward (Vf) Typical: 3.2V
• Current - Test: 20mA
• Viewing Angle: 30°
• Mounting Type: Surface Mount
• Package / Case: 4-SMD, Gull Wing
• Size / Dimension: 4.20mm L x 4.20mm W
• Height (Max): 7.00mm
• Lens Style: Round with Domed Top
• Configuration: Standard

The ALMD-CB3F-TV002 meets all substitution criteria as a direct equivalent. This part maintains identical electrical characteristics, optical specifications, and mechanical form factor while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The ALMD-CB3F-TV002 is the direct substitute for the obsolete ALMD-CB3D-STC02. Selection of the substitute part is justified by the following factors:

• Active product status ensures long-term availability and supply chain continuity
• ROHS3 compliance certification meets current regulatory requirements
• Identical electrical and optical specifications guarantee functional compatibility
• Matching mechanical form factor and package dimensions enable direct PCB layout compatibility
• Tape & Reel packaging supports automated assembly processes

The substitute part maintains all critical performance parameters while providing improved compliance posture and production viability.

Frequently Asked Questions (FAQ)

Q: Can ALMD-CB3F-TV002 be used as a direct replacement for ALMD-CB3D-STC02 in existing designs?

A: Yes. The substitute part maintains identical wavelength (470nm dominant, 464nm peak), forward voltage (3.2V), test current (20mA), viewing angle (30°), and mechanical dimensions (4.20mm x 4.20mm x 7.00mm max height). The 4-SMD gull wing package and round domed lens configuration are identical, enabling direct PCB compatibility without layout modifications.

Q: What is the difference in Moisture Sensitivity Level between these parts?

A: The main part (ALMD-CB3D-STC02) has MSL 1 (unlimited shelf life), while the substitute (ALMD-CB3F-TV002) has MSL 2A (4-week floor life after bag opening). This difference requires adherence to moisture control procedures during storage and handling of the substitute part.

Q: Does the substitute part meet current regulatory standards?

A: Yes. The ALMD-CB3F-TV002 is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The main part status is not specified for these certifications.

Q: Are there packaging differences between these parts?

A: The substitute part is supplied in Tape & Reel (TR) packaging, which is standard for automated assembly. The main part packaging format is not specified. Both parts are compatible with standard SMD pick-and-place equipment.

Q: What is the inventory status of these parts?

A: The main part (ALMD-CB3D-STC02) has 1051 pieces in stock as new original. The substitute part (ALMD-CB3F-TV002) has 1072 pieces in stock as new original. Both are available for immediate procurement.
