Key Parameters

Substitute Part Grouping Explanation

Substitution of the VLMY334BACB-GS18 is determined by strict equivalence across the following critical parameters:

• Color and Wavelength: Yellow 589nm dominant wavelength with 591nm peak wavelength
• Optical Output: 2300mcd millicandela rating
• Electrical Characteristics: 2.3V forward voltage at 50mA test current
• Mechanical Compatibility: 2-SMD, J-Lead package with 2-PLCC supplier device package, 3.00mm L x 2.80mm W dimensions, 1.85mm maximum height
• Viewing Angle: 120° viewing angle
• Lens Configuration: Round with flat top, 2.40mm diameter
• Regulatory Compliance: ROHS3 compliant, REACH unaffected status

The VLMY334BACB-GS08 meets all these parameters and serves as a direct parametric equivalent. The primary distinction is packaging format: GS18 uses cut tape packaging, while GS08 uses tape and reel (TR) format.

Parameter Comparison

Engineering Selection Recommendations

The VLMY334BACB-GS08 is the appropriate substitute for the obsolete VLMY334BACB-GS18. Both parts maintain identical electrical, optical, and mechanical specifications. The VLMY334BACB-GS08 carries active product status with significantly higher inventory availability (26,981 pcs vs. 850 pcs), ensuring supply chain continuity.

Both parts satisfy ROHS3 compliance and REACH unaffected regulatory requirements. The MSL rating of 2A (4 Weeks) applies to both variants, requiring equivalent moisture control during storage and handling.

The packaging difference—cut tape (GS18) versus tape and reel (GS08)—does not affect component functionality or PCB assembly compatibility. Selection between these formats depends on production volume and assembly equipment capabilities.

Frequently Asked Questions (FAQ)

Q: Can VLMY334BACB-GS08 be used as a direct replacement for VLMY334BACB-GS18?

A: Yes. Both parts are electrically and mechanically identical. The VLMY334BACB-GS08 is the active production equivalent of the obsolete VLMY334BACB-GS18, with identical forward voltage (2.3V), luminous intensity (2300mcd), wavelength (589nm dominant), viewing angle (120°), and package dimensions (3.00mm L x 2.80mm W x 1.85mm H).

Q: What is the difference between GS18 and GS08 packaging?

A: GS18 denotes cut tape packaging, while GS08 denotes tape and reel (TR) format. Both contain the same component in the same 2-PLCC package. The packaging format affects order quantities and assembly line compatibility but not component performance or PCB assembly outcomes.

Q: Are there any compliance differences between these parts?

A: No. Both VLMY334BACB-GS18 and VLMY334BACB-GS08 maintain identical ROHS3 compliance and REACH unaffected status. Moisture sensitivity level (MSL 2A, 4 Weeks) is identical for both variants.

Q: Why is VLMY334BACB-GS18 listed as obsolete?

A: The GS18 variant has been discontinued by Vishay Semiconductor Opto Division. The VLMY334BACB-GS08 remains in active production and serves as the current production equivalent.

Q: What are the critical parameters for substitution compatibility?

A: Substitution compatibility is determined by: color (yellow), dominant wavelength (589nm), luminous intensity (2300mcd), forward voltage (2.3V at 50mA), viewing angle (120°), lens style (round with flat top, 2.40mm diameter), package type (2-SMD, J-Lead / 2-PLCC), and physical dimensions (3.00mm L x 2.80mm W x 1.85mm H max).
