VAOL-S4RP4 Equivalent & Substitute Parts

Part Overview

The VAOL-S4RP4 is a red LED indication component in 0402 (1005 Metric) surface mount package manufactured by Visual Communications Company (VCC). This discrete LED operates at 2V forward voltage with a 52mcd brightness rating and 624nm dominant wavelength, designed for standard indication applications requiring a 120° viewing angle.

The VAOL-S4RP4 carries a "Not For New Designs" product status, making identification of equivalent substitute parts essential for ongoing production and new design implementations. Substitute components must maintain electrical compatibility across forward voltage, current ratings, and optical characteristics while meeting equivalent packaging and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VAOL-S4RP4 is determined by strict alignment across the following critical parameters:

Electrical Compatibility Requirements:

• Forward voltage (Vf) must be 2V (typical)
• Test current must be 20mA
• Red color specification (wavelength range 620-640nm acceptable)

Physical Compatibility Requirements:

• Package type: 0402 (1005 Metric) surface mount only
• Lens size: 1.00mm x 0.50mm
• Maximum height: 0.55mm
• Mounting type: Surface mount

Optical Performance Parameters:

• Dominant wavelength within red spectrum (620-640nm range)
• Millicandela rating within acceptable brightness tolerance (50-60mcd range)
• Viewing angle minimum 120°

Compliance Requirements:

• ROHS3 compliant
• REACH unaffected status
• EAR99 ECCN classification

The VLMS1500-GS08 from Vishay Semiconductor Opto Division meets all critical substitution criteria and qualifies as a direct equivalent for the VAOL-S4RP4.

Engineering Selection Recommendations

For Ongoing Production (VAOL-S4RP4 Replacement):

The VLMS1500-GS08 is a qualified direct substitute for the VAOL-S4RP4. Both components share identical electrical specifications (2V forward voltage, 20mA test current), physical dimensions (0402 package, 1.00mm x 0.50mm lens, 0.55mm maximum height), and compliance certifications (ROHS3, REACH unaffected, EAR99). The VLMS1500-GS08 provides equivalent or superior optical performance with 54mcd brightness (versus 52mcd) and 130° viewing angle (versus 120°), while maintaining red spectrum wavelength compatibility (631nm dominant versus 624nm).

For New Design Implementation:

The VLMS1500-GS08 is the recommended component selection. This part carries "Active" product status, ensuring long-term availability and supply chain stability. The Vishay CHIPLED series provides equivalent functionality with enhanced specifications and established production continuity.

Compliance Verification:

Both components meet ROHS3 compliance and REACH unaffected requirements. No additional regulatory assessment is required for direct substitution in existing applications.

Frequently Asked Questions (FAQ)

Q: Can the VLMS1500-GS08 be used as a direct replacement for VAOL-S4RP4 in existing PCB designs?

A: Yes. Both components share identical package specifications (0402), physical dimensions (1.00mm x 0.50mm lens, 0.55mm height), electrical ratings (2V forward voltage, 20mA test current), and mounting type (surface mount). No PCB layout modifications are required.

Q: What are the wavelength differences between these two parts?

A: The VAOL-S4RP4 has a dominant wavelength of 624nm (peak 632nm), while the VLMS1500-GS08 has a dominant wavelength of 631nm (peak 639nm). Both fall within the red spectrum and are visually compatible for indication applications.

Q: Is there a brightness difference between these LEDs?

A: The VLMS1500-GS08 provides 54mcd brightness compared to the VAOL-S4RP4's 52mcd. This 2mcd difference is within normal manufacturing tolerance and will not produce perceptible visual differences in indication applications.

Q: What is the viewing angle difference?

A: The VAOL-S4RP4 has a 120° viewing angle, while the VLMS1500-GS08 has a 130° viewing angle. The substitute provides a wider viewing angle, which is compatible with or superior to the original specification.

Q: Are there packaging differences between these parts?

A: The VAOL-S4RP4 is supplied in Tape & Reel (TR) packaging, while the VLMS1500-GS08 is supplied in Cut Tape (CT) & Digi-Reel® packaging. Both are standard surface mount packaging formats suitable for automated assembly.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the VAOL-S4RP4 and VLMS1500-GS08 are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: Why is the VAOL-S4RP4 marked "Not For New Designs"?

A: This designation indicates the component is in mature or end-of-life status. The VLMS1500-GS08 carries "Active" product status, making it the appropriate choice for new design implementations requiring long-term supply assurance.
