Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VFGY1104LS-TR is determined by strict alignment across the following critical parameters:

Mandatory Matching Parameters:

• Color: Yellow
• Package / Case: 2-PLCC
• Mounting Type: Surface Mount
• Lens Size: 2.40mm Dia
• Lens Style: Round with Flat Top
• Lens Transparency: Clear
• Physical Dimensions: 3.20mm L x 2.80mm W, Height Max 2.10mm
• Wavelength - Dominant: Yellow spectrum (589-590nm range)
• Viewing Angle: 120°
• RoHS Status: ROHS3 Compliant

Allowable Parameter Variation Ranges:

• Voltage - Forward (Vf): 2.2V to 2.6V (circuit design dependent)
• Current - Test: 20mA to 50mA (application dependent)
• Millicandela Rating: Minimum 645mcd (brightness requirement)

The substitute part LY T68F-T2V2-35-1-20-R18-Z meets all mandatory matching criteria and operates within allowable electrical parameter ranges for yellow LED indication applications.

Engineering Selection Recommendations

VFGY1104LS-TR (Stanley Electric Co)

Primary selection for applications requiring 2.6V forward voltage operation at 50mA test current. Active product status with 3400 units in inventory. ROHS3 compliant with MSL 2A rating (4 weeks moisture sensitivity). Suitable for standard yellow indication circuits with established Stanley Electric supply chain qualification.

LY T68F-T2V2-35-1-20-R18-Z (ams-OSRAM USA INC.)

Substitute selection for applications compatible with 2.2V forward voltage operation at 20mA test current. Active product status with 2355 units in inventory. ROHS3 compliant with MSL 3 rating (168 hours moisture sensitivity). Delivers higher brightness output (737.5mcd versus 645mcd) within identical 2-PLCC package footprint. Both parts maintain identical physical dimensions, lens configuration, and optical characteristics within yellow spectrum range.

Both components satisfy ROHS3, REACH, and EAR99 export compliance requirements. Selection between primary and substitute part depends on circuit voltage and current design specifications.

Frequently Asked Questions (FAQ)

Q: Can LY T68F-T2V2-35-1-20-R18-Z replace VFGY1104LS-TR in existing designs?

A: Substitution is compatible when circuit design accommodates 2.2V forward voltage and 20mA test current operation. Both components share identical 2-PLCC package footprint, physical dimensions (3.20mm L x 2.80mm W, 2.10mm max height), and optical properties (120° viewing angle, 2.40mm round lens with flat top, clear transparency). PCB layout and solder reflow profiles remain unchanged.

Q: What are the key electrical differences between these parts?

A: VFGY1104LS-TR operates at 2.6V forward voltage with 50mA test current and 645mcd brightness. LY T68F-T2V2-35-1-20-R18-Z operates at 2.2V forward voltage with 20mA test current and 737.5mcd brightness. The substitute part delivers higher luminous intensity at lower operating current, requiring circuit design verification for voltage and current compatibility.

Q: Are the moisture sensitivity levels compatible?

A: VFGY1104LS-TR carries MSL 2A rating (4 weeks). LY T68F-T2V2-35-1-20-R18-Z carries MSL 3 rating (168 hours). Both ratings are within standard surface mount component handling specifications. Storage and reflow process requirements differ; refer to respective manufacturer datasheets for specific moisture precautions.

Q: Do both parts meet regulatory compliance requirements?

A: Both VFGY1104LS-TR and LY T68F-T2V2-35-1-20-R18-Z are ROHS3 compliant, REACH unaffected, classified as EAR99, and share identical HTSUS code 8541.41.0000. Regulatory compliance is equivalent for both components.

Q: What is the wavelength compatibility between these yellow LEDs?

A: VFGY1104LS-TR has dominant wavelength 589nm (peak 594nm). LY T68F-T2V2-35-1-20-R18-Z has dominant wavelength 590nm (peak 597nm). Both operate within yellow spectrum range with negligible visual difference in color perception for indication applications.

Q: Are there packaging or tape & reel differences?

A: Both components are supplied in Tape & Reel (TR) packaging format. Physical package configuration is identical 2-PLCC. Reel specifications and tape dimensions may differ between manufacturers; contact suppliers for specific tape and reel documentation.
