Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WP5603ZGDL/SD/G is determined by the following critical parameters:

Primary Compatibility Criteria:

• Color: Green
• Lens Transparency: Diffused
• Lens Style: Oval with Domed Top
• Mounting Type: Through Hole
• Package / Case: Radial (5mm Oval)
• Test Current: 20mA

Allowable Parameter Variations:

• Forward Voltage (Vf): ±0.3V tolerance acceptable for standard indication circuits
• Millicandela Rating: Brightness variations within ±60% acceptable for indication applications
• Wavelength - Dominant: ±5nm variation acceptable within green spectrum (520-530nm range)
• Viewing Angle: Variations acceptable based on application requirements
• Height: Variations acceptable within PCB layout constraints
• Compliance Status: RoHS and REACH compliance required

The substitute part C566D-GFF-CY14Q7S1 from CreeLED, Inc. meets all primary compatibility criteria and operates within allowable parameter variations.

Engineering Selection Recommendations

WP5603ZGDL/SD/G Selection Criteria:

• Primary choice for applications requiring maximum height constraint of 7.00mm
• Preferred for designs with symmetric viewing angle requirements (80° x 40°)
• Suitable for standard indication circuits operating at 3.2V forward voltage
• RoHS3 compliance provides enhanced environmental standards

C566D-GFF-CY14Q7S1 Selection Criteria:

• Suitable for applications where increased brightness (7980mcd) is beneficial
• Acceptable for designs with PCB height allowance up to 11.90mm
• Appropriate for narrower viewing angle applications (70° x 30°)
• RoHS compliant for standard regulatory requirements
• Forward voltage of 3.4V requires circuit verification for compatibility

Substitution Feasibility: Both parts are active products with unlimited moisture sensitivity rating and REACH unaffected status. Selection between these components depends on specific application constraints regarding physical height, brightness requirements, and circuit voltage tolerance. The 0.2V forward voltage difference requires verification in the target circuit design to ensure proper LED operation and current limiting resistor calculations.

Frequently Asked Questions (FAQ)

Q: Can C566D-GFF-CY14Q7S1 directly replace WP5603ZGDL/SD/G without circuit modification?

A: Direct replacement requires circuit verification. The forward voltage difference of 0.2V (3.4V vs 3.2V) may affect current limiting resistor calculations. The increased height (11.90mm vs 7.00mm) must be verified against PCB layout constraints. Brightness increase (7980mcd vs 5000mcd) is generally acceptable for indication applications.

Q: What are the critical parameters that must match for substitution?

A: Color (Green), lens transparency (Diffused), lens style (Oval with Domed Top), mounting type (Through Hole), package type (Radial 5mm Oval), and test current (20mA) must remain constant. These parameters define the functional and mechanical compatibility of the component.

Q: Are there viewing angle differences between these parts?

A: Yes. WP5603ZGDL/SD/G provides 80° x 40° viewing angles, while C566D-GFF-CY14Q7S1 provides 70° x 30° viewing angles. The substitute part has a narrower viewing angle, which may affect visibility in applications requiring wide-angle indication.

Q: Do both parts meet current compliance requirements?

A: Both parts are RoHS compliant and REACH unaffected. WP5603ZGDL/SD/G carries RoHS3 compliance (enhanced standard), while C566D-GFF-CY14Q7S1 carries RoHS compliance. Both meet standard regulatory requirements for industrial and consumer applications.

Q: What is the impact of the 4.90mm height difference?

A: The substitute part is 4.90mm taller (11.90mm vs 7.00mm). This difference must be evaluated against available PCB clearance, enclosure height, and mechanical assembly constraints. Height verification is mandatory before component selection.

Q: How does the brightness difference affect application performance?

A: The substitute part delivers 59.6% higher brightness (7980mcd vs 5000mcd). For indication applications, this increase is generally acceptable and may improve visibility. However, circuit current limiting must remain at 20mA test current to prevent over-driving the LED.
