Substitute Part Grouping Explanation

Substitute parts for the 5219408F are identified based on the following critical parameters that determine functional compatibility:

• Color: Green
• Lens Size: 3.00mm Dia
• Lens Transparency: Diffused
• Mounting Type: Through Hole
• Package / Case: Radial
• Wavelength Range: Green spectrum (560-575nm acceptable)
• Forward Voltage: 2.1V to 2.2V range
• Test Current: 10mA to 20mA range

The identified substitutes maintain the same physical form factor, optical characteristics, and electrical operating parameters within acceptable engineering tolerances. Both substitute parts are active products with current manufacturing status and full compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with current manufacturing support and full regulatory compliance. The 5219210F maintains identical electrical parameters (2.1V, 10mA) and is manufactured by the same supplier as the original part, offering the closest functional match. The WP3A8GD from Kingbright operates at a slightly elevated forward voltage (2.2V) and test current (20mA) with increased brightness output (20mcd), suitable for applications where higher luminous intensity is acceptable within the circuit design constraints.

Selection between substitutes depends on circuit design requirements: the 5219210F is preferred for direct parameter matching, while the WP3A8GD is suitable for designs tolerating higher brightness and slightly elevated power consumption. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with modern manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can the 5219210F directly replace the 5219408F without circuit modification?

A: Yes. The 5219210F shares identical forward voltage (2.1V) and test current (10mA) specifications, maintaining the same electrical operating point. Physical dimensions are compatible with standard 3mm LED mounting footprints.

Q: What are the key differences between the WP3A8GD and the original 5219408F?

A: The WP3A8GD operates at 2.2V forward voltage and 20mA test current compared to the 5219408F's 2.1V and 10mA. The WP3A8GD provides higher brightness (20mcd versus 16mcd) and a slightly narrower viewing angle (50° versus 45°). Circuit current-limiting resistor values may require adjustment to accommodate the higher test current specification.

Q: Are all three parts compatible with the same PCB footprint?

A: All three parts use 3mm through-hole radial packages with compatible lead spacing. Physical height variations (5.00mm to 6.48mm maximum) are within standard PCB assembly tolerances for through-hole components.

Q: What compliance certifications apply to the substitute parts?

A: Both 5219210F and WP3A8GD are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: Why is the 5219408F classified as obsolete?

A: The 5219408F is no longer in active production. The identified substitutes provide equivalent or superior performance characteristics while maintaining current manufacturing status and regulatory compliance.
