The Kingbright WP1533BQ/GD meets these substitution criteria with minor parameter variations within acceptable engineering tolerances.

Parameter Comparison

Engineering Selection Recommendations

The Kingbright WP1533BQ/GD qualifies as a functional substitute for the obsolete VCC 5308H5 based on the following engineering criteria:

Compliance Alignment: Both components maintain ROHS3 compliance and MSL Rating 1 (Unlimited), ensuring regulatory and environmental compatibility with existing design specifications.

Electrical Equivalence: Voltage rating (2.2V) and color (green) are identical. Peak wavelength variation (563nm to 565nm) falls within acceptable tolerance for green LED circuit board indicators. Forward current rating increase (20mA to 25mA) is compatible with standard current-limiting circuit designs.

Mechanical Compatibility: Both components feature through-hole, right-angle mounting with round domed-top lens styles, ensuring PCB footprint compatibility. The larger lens diameter (4.70mm versus 2.00mm) requires verification of available PCB clearance in the target application.

Operational Considerations: The WP1533BQ/GD delivers lower luminous intensity (50mcd versus 100mcd) and features a diffused lens versus tinted lens. These characteristics alter the light distribution pattern and brightness profile. Applications requiring maximum brightness or specific optical characteristics should evaluate whether reduced intensity and diffused optics meet functional requirements.

Supply Chain Status: The WP1533BQ/GD is actively manufactured and maintains substantial inventory availability (4896 pcs), providing reliable long-term supply compared to the obsolete 5308H5.

Frequently Asked Questions (FAQ)

Q: Can the WP1533BQ/GD directly replace the 5308H5 without circuit modification?

A: The WP1533BQ/GD is electrically compatible at the 2.2V operating voltage. However, the higher forward current rating (25mA versus 20mA) and lower luminous intensity (50mcd versus 100mcd) may require evaluation of the current-limiting resistor and brightness requirements in the target circuit. PCB layout verification is necessary due to the larger lens diameter.

Q: What is the impact of the diffused lens on the 5308H5 application?

A: The WP1533BQ/GD features a diffused, tinted lens compared to the tinted lens of the 5308H5. Diffused lenses scatter light over a wider area, reducing peak brightness in the direct viewing direction but improving visibility from off-axis angles. Applications requiring concentrated light output in a specific direction should evaluate this optical difference.

Q: Is the 4.70mm lens diameter compatible with 2.00mm PCB mounting holes?

A: The WP1533BQ/GD requires a larger mounting hole or clearance area due to its 4.70mm lens diameter. PCB layout must be verified to ensure adequate clearance around the component mounting location. Mechanical interference with adjacent components or board features must be assessed.

Q: Are there any compliance or certification differences between the two parts?

A: Both components are ROHS3 compliant, REACH unaffected, and carry MSL Rating 1 (Unlimited). No compliance or certification differences exist. Both are classified under HTSUS 8541.41.0000 and ECCN EAR99.

Q: What is the wavelength tolerance between 563nm and 565nm?

A: The 2nm difference between the 5308H5 (563nm) and WP1533BQ/GD (565nm) is within standard manufacturing tolerance for green LEDs and is not visually distinguishable in circuit board indicator applications. Both wavelengths fall within the green spectrum range.

Q: How does the 60° viewing angle of the WP1533BQ/GD affect visibility?

A: The specified 60° viewing angle indicates the cone of light within which the LED maintains acceptable brightness. The diffused lens of the WP1533BQ/GD contributes to this wider viewing angle compared to tinted lenses, which typically have narrower viewing angles. This characteristic improves visibility from off-axis positions.
