Substitute Part Grouping Explanation

Substitution eligibility for the VLMS33S1T2-GS08 is determined by strict equivalence across the following critical parameters:

• Color: Red
• Wavelength - Dominant: 630nm
• Wavelength - Peak: 641nm
• Voltage - Forward (Vf) Typical: 2V
• Current - Test: 30mA
• Viewing Angle: 120°
• Lens Style: Round with Flat Top
• Lens Size: 2.40mm Dia
• Package / Case: 2-SMD, J-Lead
• Size / Dimension: 3.00mm L x 2.80mm W
• Height (Max): 1.85mm
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 2A (4 Weeks)

The VLMS33S1U1-GS08 meets all substitution criteria. Variations in millicandela rating (315mcd vs. 370mcd) do not disqualify substitution when the substitute part maintains all other electrical and mechanical specifications within the defined parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the VLMS33S1T2-GS08 and VLMS33S1U1-GS08 are Active status components manufactured by Vishay Semiconductor Opto Division. Both parts are ROHS3 compliant and carry identical MSL ratings of 2A (4 Weeks), ensuring equivalent handling and storage requirements. The parts share identical electrical specifications (2V forward voltage, 30mA test current) and mechanical dimensions (3.00mm L x 2.80mm W, 1.85mm max height). Selection between these parts may be based on inventory availability, lead time, or application-specific luminous intensity requirements. The VLMS33S1U1-GS08 provides higher luminous intensity at 370mcd compared to 315mcd for the VLMS33S1T2-GS08, while maintaining all other parameters.

Frequently Asked Questions (FAQ)

Q: Can VLMS33S1U1-GS08 be used as a direct replacement for VLMS33S1T2-GS08?

A: Yes. Both parts share identical electrical specifications (2V forward voltage, 30mA test current), optical characteristics (630nm dominant wavelength, 641nm peak wavelength), mechanical dimensions (3.00mm L x 2.80mm W, 1.85mm max height), and package configuration (2-SMD, J-Lead). Both are ROHS3 compliant with 2A MSL ratings.

Q: What is the difference between these two parts?

A: The primary difference is the millicandela rating. The VLMS33S1U1-GS08 provides 370mcd luminous intensity compared to 315mcd for the VLMS33S1T2-GS08. All other electrical, optical, and mechanical parameters are identical.

Q: Are there any compatibility concerns with PCB assembly?

A: No. Both parts use identical 2-SMD, J-Lead packaging with matching dimensions and surface mount configuration. PCB footprints, reflow profiles, and assembly processes remain unchanged.

Q: Do these parts have different storage or handling requirements?

A: No. Both parts carry identical Moisture Sensitivity Level (MSL) ratings of 2A (4 Weeks), requiring the same storage conditions and handling procedures.

Q: Can I mix these parts in the same production batch?

A: Yes, provided your application design accommodates the luminous intensity variation. The VLMS33S1U1-GS08 with higher brightness may be suitable for applications requiring increased visibility, while the VLMS33S1T2-GS08 is appropriate for standard indication applications.
