VAOL-S8YP4 Yellow LED 0805 SMD - Equivalent & Substitute Parts

Part Overview

The VAOL-S8YP4 is a yellow LED indicator in 0805 (2012 Metric) surface mount package manufactured by Visual Communications Company (VCC). This component operates at 2V forward voltage with a dominant wavelength of 589nm and provides 92mcd luminous intensity at 20mA test current. The product is classified as obsolete, necessitating identification of active equivalent components for new designs and ongoing production requirements. Substitute parts must maintain electrical compatibility, mechanical fit, and compliance certifications while offering continued availability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VAOL-S8YP4 are identified based on strict electrical and mechanical parameter alignment. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Package classification: 0805 (2012 Metric) surface mount only
• Color specification: Yellow LEDs only
• Lens transparency: Clear lens required
• Forward voltage: 2V nominal operation
• Test current: 20mA reference condition
• Dominant wavelength: 589nm ± acceptable tolerance range (588-592nm)
• Viewing angle: 140° standard
• Physical dimensions: 2.00mm L x 1.25mm W footprint
• Compliance: ROHS3 Compliant, REACH Unaffected

Acceptable Variation Parameters:

• Millicandela rating: Substitute may exceed original specification (higher brightness acceptable)
• Height: Substitute must not exceed 1.30mm maximum
• Wavelength - Peak: May vary within yellow spectrum (590-595nm acceptable)
• Moisture Sensitivity Level: May differ if storage conditions accommodate
• Product status: Active status preferred for long-term availability

The substitute part 150080YS75000 from Würth Elektronik meets all critical parameters and qualifies as a direct functional equivalent.

Engineering Selection Recommendations

The 150080YS75000 from Würth Elektronik qualifies as a direct substitute for the obsolete VAOL-S8YP4 based on the following engineering criteria:

Electrical Compatibility: Forward voltage, test current, dominant wavelength, and viewing angle are identical between components. The 1nm difference in dominant wavelength (589nm vs 590nm) and 4nm difference in peak wavelength (591nm vs 595nm) remain within acceptable yellow LED specification tolerances and produce visually equivalent color output.

Mechanical Compatibility: Both components share identical 0805 (2012 Metric) package dimensions (2.00mm L x 1.25mm W) and surface mount configuration. The substitute part features a lower maximum height (0.80mm vs 1.30mm), providing improved clearance characteristics for PCB assembly and component stacking applications.

Performance Enhancement: The substitute part delivers 120mcd luminous intensity compared to the original 92mcd specification, representing a 30% brightness increase at identical operating conditions. This enhanced brightness maintains backward compatibility while improving visibility in indication applications.

Regulatory and Compliance Status: Both components maintain ROHS3 compliance and REACH unaffected status. Export classification (EAR99) and tariff codes (HTSUS 8541.41.0000) are identical, ensuring no regulatory complications in component substitution.

Availability and Product Status: The substitute part maintains active product status with substantial inventory availability (33,849 pcs), ensuring long-term supply continuity compared to the obsolete VAOL-S8YP4 status.

Moisture Sensitivity Consideration: The substitute part carries MSL 3 (168 Hours) rating compared to MSL 2 (1 Year) for the original component. This represents a more stringent moisture sensitivity requirement and necessitates adherence to reduced storage and handling timeframes during component preparation and assembly.

Frequently Asked Questions (FAQ)

Q: Can the 150080YS75000 be used as a direct replacement in existing VAOL-S8YP4 designs?

A: Yes. The substitute part maintains identical electrical parameters (2V forward voltage, 20mA test current, 589-590nm dominant wavelength, 140° viewing angle) and mechanical specifications (0805 package, 2.00mm x 1.25mm footprint, surface mount configuration). No circuit modifications are required.

Q: What is the significance of the 30mcd brightness difference between the two parts?

A: The 150080YS75000 provides 120mcd versus the original 92mcd specification. This increased brightness is a performance enhancement that maintains backward compatibility. Applications designed for 92mcd operation will function correctly with the brighter substitute part. No design changes are necessary.

Q: Are there any height clearance issues with the substitute part?

A: No. The 150080YS75000 features a maximum height of 0.80mm compared to the original 1.30mm specification. The substitute part is lower profile, providing improved clearance for component stacking and conformal coating applications.

Q: How do the wavelength specifications compare?

A: The original VAOL-S8YP4 specifies 589nm dominant wavelength with 591nm peak wavelength. The substitute 150080YS75000 specifies 590nm dominant wavelength with 595nm peak wavelength. Both values fall within the yellow LED spectrum (typically 570-595nm) and produce visually equivalent yellow color output. The 1nm and 4nm differences are imperceptible to human vision.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: The original component is supplied in Cut Tape (CT) and Digi-Reel® format, while the substitute is supplied in standard Tape & Reel (TR) format. Both packaging types are compatible with automated pick-and-place assembly equipment. Tape & Reel format typically offers better handling efficiency for high-volume production.

Q: Does the different Moisture Sensitivity Level (MSL) rating affect component usability?

A: The substitute part carries MSL 3 (168 Hours) compared to MSL 2 (1 Year) for the original component. This indicates a more stringent moisture sensitivity requirement. Components must be stored in controlled humidity conditions and used within 168 hours of package opening. Standard moisture-controlled storage and handling procedures accommodate this requirement without affecting component performance or reliability.

Q: Are both components RoHS3 compliant?

A: Yes. Both the VAOL-S8YP4 and 150080YS75000 maintain ROHS3 compliance and REACH unaffected status. No regulatory complications arise from component substitution.

Q: What is the Series designation for the substitute part?

A: The 150080YS75000 belongs to the Würth Elektronik WL-SMCW series, which encompasses surface mount LED indicators in 0805 package configuration.

Q: Can the substitute part be used in new designs?

A: Yes. The 150080YS75000 maintains active product status with substantial inventory availability, making it suitable for both replacement applications and new design implementations. The active status ensures long-term supply continuity.
