WP169XGD Equivalent & Substitute Parts Reference

Part Overview

The WP169XGD is an active-status green diffused rectangular through-hole LED manufactured by Kingbright, designed for indication applications. This component operates at 2.2V forward voltage with a 20mA test current and delivers 15mcd luminous intensity. The part is ROHS3 compliant and maintains unlimited moisture sensitivity rating (MSL 1), making it suitable for standard industrial and consumer electronics applications. Substitute parts may be required due to inventory constraints, design optimization for specific viewing angles or brightness levels, or mechanical form factor requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WP169XGD is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Color: Green
• Wavelength - Dominant: 568nm
• Wavelength - Peak: 565nm
• Voltage - Forward (Vf) Typical: 2.2V
• Current - Test: 20mA
• Mounting Type: Through Hole
• Lens Transparency: Diffused
• Package / Case: Radial
• RoHS Status: ROHS3 Compliant
• Product Status: Active

Variable Parameters (Allowable Differences):

• Millicandela Rating: May vary based on application brightness requirements
• Viewing Angle: May vary based on application field-of-view requirements
• Lens Style: May vary (domed top vs. flat top) based on mechanical constraints
• Physical Dimensions: May vary within through-hole LED form factor constraints

The WP914GDT qualifies as a substitute part because it maintains all mandatory matching parameters while offering alternative specifications in millicandela rating, viewing angle, lens style, and physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

Both WP169XGD and WP914GDT are active-status products manufactured by Kingbright with identical electrical specifications (2.2V forward voltage, 20mA test current, 568nm dominant wavelength). Both components are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Selection Criteria:

WP169XGD is the primary choice when:

• Higher luminous intensity (15mcd) is required for the application
• Narrower viewing angle (60°) is acceptable or preferred
• Domed lens style is mechanically compatible with the PCB layout
• Maximum component height of 5.00mm is within design constraints

WP914GDT is the appropriate substitute when:

• Lower luminous intensity (6mcd) is sufficient for the application
• Wider viewing angle (100°) is required for broader light distribution
• Flat-top lens style is preferred for mechanical or aesthetic reasons
• Reduced component height (4.00mm maximum) is beneficial for compact designs
• Smaller footprint (3.00mm length vs. 4.00mm) accommodates space-constrained layouts

Both parts maintain identical electrical performance and regulatory compliance, ensuring circuit-level compatibility when substituted.

Frequently Asked Questions (FAQ)

Q: Can WP914GDT replace WP169XGD in any application?

A: WP914GDT is electrically compatible with WP169XGD due to identical forward voltage (2.2V), test current (20mA), and wavelength specifications (568nm dominant). However, the substitute delivers lower brightness (6mcd vs. 15mcd) and offers a wider viewing angle (100° vs. 60°). Substitution is valid only when the application can tolerate reduced luminous intensity and the wider viewing angle is acceptable or beneficial.

Q: What are the mechanical differences between these parts?

A: WP169XGD features a domed-top lens with maximum height of 5.00mm and 4.00mm length. WP914GDT features a flat-top lens with maximum height of 4.00mm and 3.00mm length. Both maintain identical lens size (3.00mm x 2.00mm) and radial through-hole mounting. The WP914GDT's reduced height and length may provide advantages in space-constrained PCB designs.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both WP169XGD and WP914GDT are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components in industrial and consumer applications.

Q: What is the impact of the 40° viewing angle difference?

A: WP169XGD provides a 60° viewing angle, concentrating light output in a narrower cone. WP914GDT provides a 100° viewing angle, distributing light across a wider field. Applications requiring broad light distribution benefit from WP914GDT, while applications requiring focused indication benefit from WP169XGD's narrower angle.

Q: How does the 9mcd brightness difference affect circuit design?

A: Both parts operate at identical electrical specifications (2.2V, 20mA), requiring no circuit modifications for substitution. The brightness difference (15mcd vs. 6mcd) affects only visual perception. Applications where indicator brightness is critical to user visibility should retain WP169XGD. Applications where lower brightness is acceptable or preferred can use WP914GDT without circuit redesign.

Q: Are the parts interchangeable on the same PCB footprint?

A: Both parts use radial through-hole mounting with identical pin configuration. However, the different physical dimensions (height and length) may require PCB layout verification. WP914GDT's smaller footprint (3.00mm L x 4.00mm H) fits within WP169XGD's space envelope (4.00mm L x 5.00mm H), allowing mechanical substitution in most layouts. Verify clearance for the domed vs. flat lens style if the PCB has height-sensitive components or enclosure constraints.
