VAOL-SO1XAX-SA LED Module 1W STAR Orange Equivalent & Substitute Parts

Part Overview

The VAOL-SO1XAX-SA is a 1W STAR series LED module manufactured by Visual Communications Company (VCC) in orange color with a starboard configuration. This component is classified as Not For New Designs, indicating it has reached end-of-life status. The module delivers 55 lumens at typical operating conditions with a wavelength of 615nm and forward voltage of 2.5V at 350mA test current.

Due to the Not For New Designs status, identification of functionally equivalent substitute components is necessary for ongoing production support, maintenance applications, and design continuity where this module was previously specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the VAOL-SO1XAX-SA is evaluated based on the following critical parameters that define functional equivalence:

Electrical Compatibility:

• Forward voltage (Vf): 2.5V nominal
• Maximum current rating: 350mA
• Test current: 350mA

Optical Characteristics:

• Color specification: Orange wavelength range (615nm)
• Configuration: Starboard mounting
• Lens type: Domed

Physical Compatibility:

• Package form factor: LED Module with starboard configuration
• Mechanical dimensions: Circular or rectangular footprint compatible with 19.90mm diameter reference

Regulatory Compliance:

• RoHS3 compliance required
• REACH unaffected status
• ECCN EAR99 classification

The substitute part AAD1-9090SE28ZC-S from Kingbright meets the core electrical parameters (2.5V Vf, 350mA maximum current) and regulatory requirements (RoHS3, REACH unaffected, EAR99). Both components feature starboard configuration with domed lenses and operate within compatible current ranges. Differences in luminous flux output and efficiency are noted in the parameter comparison table below.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: Product Status

The VAOL-SO1XAX-SA carries a Not For New Designs designation, making it unsuitable for new product development. The AAD1-9090SE28ZC-S from Kingbright maintains Active product status, ensuring ongoing manufacturer support, availability, and compliance updates.

Electrical Compatibility

Both components share identical forward voltage (2.5V) and maximum current ratings (350mA), enabling direct substitution in existing circuit designs without modification to current-limiting resistors or power supply specifications.

Regulatory and Compliance Alignment

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and hazardous substance restrictions. Both are classified under ECCN EAR99 and HTSUS code 8541.41.0000, maintaining consistent export and tariff classification.

Performance Differences

The VAOL-SO1XAX-SA delivers higher luminous flux (55lm vs. 30lm) and superior efficiency (63 lm/W vs. 34 lm/W). The AAD1-9090SE28ZC-S provides a wider viewing angle (135° vs. 120°) and slightly increased height (8.30mm vs. 6.10mm). Wavelength differs by 10nm (615nm vs. 625nm), shifting the color point toward red in the substitute part.

Mechanical Fit Verification

The substitute part features rectangular dimensions (19.75mm L × 19.05mm W) compared to the circular 19.90mm diameter of the original. Height increase from 6.10mm to 8.30mm requires verification of available clearance in the target application. Starboard configuration is maintained in both components.

Moisture Sensitivity Handling

The VAOL-SO1XAX-SA specifies MSL 2A (4 weeks), while the AAD1-9090SE28ZC-S specifies MSL 4 (72 hours). The substitute part requires more stringent moisture control during storage and handling. Verify that existing moisture management procedures accommodate the shorter MSL 4 window.

Frequently Asked Questions (FAQ)

Q: Can the AAD1-9090SE28ZC-S directly replace the VAOL-SO1XAX-SA in existing designs?

A: Electrical substitution is direct due to matching forward voltage (2.5V) and current ratings (350mA). However, mechanical fit must be verified. The substitute part is rectangular (19.75mm × 19.05mm) versus circular (19.90mm diameter), and height increases from 6.10mm to 8.30mm. Verify available PCB footprint space and clearance above the component before implementation.

Q: What is the impact of the 10nm wavelength difference (615nm vs. 625nm)?

A: The wavelength shift from 615nm to 625nm moves the color point from pure orange toward orange-red. In applications where precise color matching is critical (such as indicator panels or display backlighting), this difference may be visually perceptible. In general illumination applications, the color shift is typically acceptable.

Q: Why does the substitute part have lower luminous flux (30lm vs. 55lm)?

A: The AAD1-9090SE28ZC-S is from the Kingbright Xpower series, which operates at different optical efficiency characteristics than the VCC 1W STAR series. Applications requiring the full 55 lumens output may not achieve equivalent brightness with the substitute part. Verify that the lower flux output (30lm) meets the application's illumination requirements.

Q: How does the MSL 4 rating affect component handling?

A: MSL 4 (72 hours) is more restrictive than MSL 2A (4 weeks). The substitute part must be stored in controlled humidity conditions and used within 72 hours of opening the moisture barrier bag. Existing inventory management procedures designed for MSL 2A components must be updated to accommodate the shorter MSL 4 window to prevent moisture absorption and potential solder joint failures.

Q: Are there any export or tariff implications when switching to the Kingbright part?

A: Both components share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, eliminating changes to export documentation or tariff treatment. No additional compliance review is required from a trade classification perspective.

Q: What is the significance of the wider viewing angle in the substitute part (135° vs. 120°)?

A: The AAD1-9090SE28ZC-S provides a 15° wider viewing angle, resulting in more uniform light distribution across a broader angular range. This may be advantageous in applications requiring wide-angle illumination but may be unnecessary in applications where the narrower 120° angle of the original part was intentional for focused light output.
