Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VLMS333T2V2-GS18 is determined by the following critical parameters:

• Forward voltage (Vf): 2V
• Test current: 20mA
• Package type: 2-SMD, J-Lead
• Physical dimensions: 3.00mm L x 2.80mm W, 1.85mm height maximum
• Mounting type: Surface Mount
• Lens configuration: Round with Flat Top, 2.40mm diameter
• Viewing angle: 120°
• Color: Red

Two active substitute parts meet these electrical and mechanical requirements while maintaining compatibility with the original design specifications.

Parameter Comparison

Engineering Selection Recommendations

VLMS333T2V2-GS08 is the direct functional equivalent to the obsolete VLMS333T2V2-GS18. Both parts share identical electrical characteristics (2V forward voltage, 20mA test current, 550mcd brightness) and mechanical specifications (package type, dimensions, lens configuration). The primary difference is product status: VLMS333T2V2-GS08 is active with 31,027 units in stock. This part maintains the same series designation (VLM.333) and wavelength specification (630nm dominant, 639nm peak).

VLMR335U1V2-GS08 provides an alternative with automotive-grade qualification (AEC-Q101) and extended moisture sensitivity rating (2 vs. 2A). This part operates within the same electrical envelope (2V, 20mA) and physical form factor. The wavelength differs slightly (625nm dominant, 632nm peak) but remains within the red spectrum classification. The millicandela rating is marginally higher at 560mcd. This option is suitable for applications requiring automotive-grade components.

Both substitute parts are ROHS3 compliant and available in Tape & Reel packaging for production environments.

Frequently Asked Questions (FAQ)

Q: Can VLMS333T2V2-GS08 be used as a direct replacement for VLMS333T2V2-GS18?

A: Yes. Both parts share identical electrical specifications (2V forward voltage, 20mA test current, 550mcd brightness), mechanical dimensions (3.00mm L x 2.80mm W, 1.85mm height), and package configuration (2-SMD, J-Lead). The primary distinction is that VLMS333T2V2-GS08 is active production status while the original is obsolete.

Q: What is the difference between VLMS333T2V2-GS08 and VLMR335U1V2-GS08?

A: Both parts meet the core electrical and mechanical requirements. VLMR335U1V2-GS08 carries automotive-grade qualification (AEC-Q101) and has an extended moisture sensitivity rating (2 vs. 2A). The wavelength differs slightly: VLMS333T2V2-GS08 is 630nm dominant while VLMR335U1V2-GS08 is 625nm dominant. Brightness is comparable (550mcd vs. 560mcd).

Q: Are the physical dimensions identical across all three parts?

A: Yes. All three parts share identical dimensions: 3.00mm length, 2.80mm width, and 1.85mm maximum height. The lens configuration is identical: Round with Flat Top, 2.40mm diameter.

Q: What packaging formats are available?

A: The obsolete VLMS333T2V2-GS18 was supplied in bulk packaging. Both active substitutes (VLMS333T2V2-GS08 and VLMR335U1V2-GS08) are available in Tape & Reel (TR) format for production environments.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both VLMS333T2V2-GS08 and VLMR335U1V2-GS08 are ROHS3 compliant.
