Key Parameters

Substitute Part Grouping Explanation

Substitute part identification for the WP73EB/2GDA is based on the following allowable parameter variations:

Strict Compatibility Requirements (No Variation Allowed):

• Configuration: 2 High (bi-level assembly)
• Color: Green (x 2)
• Voltage Rating: 2.2V
• Mounting Type: Through Hole, Right Angle
• RoHS Status: ROHS3 Compliant

Allowable Parameter Variations (Within Functional Tolerance):

• Current Rating: Substitute parts may operate at lower current (20mA vs. 25mA) provided the circuit design accommodates the reduced power consumption
• Millicandela Rating: Substitute parts may have lower brightness (34mcd vs. 40mcd) if visual indication requirements do not mandate maximum brightness
• Viewing Angle: Substitute parts may have reduced viewing angle (50° vs. 60°) if application does not require wide-angle visibility
• Wavelength - Peak: Substitute parts within 2nm variance (563nm vs. 565nm) maintain color consistency within human perception tolerance
• Lens Size: Substitute parts with different lens dimensions require mechanical re-evaluation for panel fit and aesthetic compatibility

The substitute part 5520822F from Dialight meets all strict compatibility requirements and operates within allowable parameter variations for current, brightness, viewing angle, and wavelength specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (WP73EB/2GDA): The WP73EB/2GDA is the specified component for applications requiring the full 25mA current rating, 40mcd brightness output, and 60° viewing angle. This part maintains Active product status with established supply chain availability (1062 pcs in stock). Selection is appropriate when maximum brightness and wide viewing angle are design requirements.

Substitute Part Selection (5520822F): The 5520822F is functionally compatible for applications where the reduced current rating (20mA), lower brightness (34mcd), and narrower viewing angle (50°) are acceptable. This substitute is appropriate for cost optimization, alternative sourcing, or inventory management purposes. The part maintains Active product status with higher current inventory availability (1807 pcs in stock). Both parts carry identical RoHS3 compliance and REACH unaffected status, ensuring regulatory equivalence.

Compliance Equivalence: Both parts are ROHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) rating. No additional compliance evaluation is required for substitution.

Frequently Asked Questions (FAQ)

Q: Can the 5520822F substitute for the WP73EB/2GDA in all applications?

A: The 5520822F is functionally compatible provided the application tolerates reduced current consumption (20mA vs. 25mA), lower brightness output (34mcd vs. 40mcd), and narrower viewing angle (50° vs. 60°). Circuit design must accommodate the lower current rating. Visual indication requirements must not mandate maximum brightness or wide-angle visibility.

Q: What is the impact of the 5mA current difference?

A: The 5520822F operates at 20mA compared to the WP73EB/2GDA at 25mA. This reduces power consumption by 20% and generates lower heat dissipation. Driver circuits designed for 25mA operation will function with the 5520822F; however, brightness output will be proportionally reduced to 34mcd.

Q: Are there mechanical compatibility issues between these parts?

A: Both parts feature Through Hole, Right Angle mounting. The WP73EB/2GDA has a 4.80mm lens diameter; the 5520822F lens dimensions are not specified in the provided data. Mechanical fit verification is required if panel cutouts or mechanical fixtures are pre-designed for the 4.80mm specification.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the WP73EB/2GDA and 5520822F are ROHS3 Compliant, REACH Unaffected, and carry identical MSL 1 (Unlimited) ratings. No additional compliance documentation is required for substitution.

Q: What is the wavelength difference between these parts?

A: The WP73EB/2GDA has a peak wavelength of 565nm; the 5520822F is 563nm. This 2nm difference is within human color perception tolerance for green LEDs and does not result in visible color variation.

Q: Which part should be selected for new designs?

A: For new designs, select based on application requirements. If maximum brightness and wide viewing angle are required, specify the WP73EB/2GDA. If power consumption optimization or cost reduction is a priority and reduced brightness and viewing angle are acceptable, specify the 5520822F. Both parts carry Active product status.
