LED GREEN DIFFUSED 5MM ROUND T/H 333VGD

Part Overview

The 333VGD is an active green LED indication component manufactured by Everlight Electronics Co Ltd, designed for through-hole mounting applications. This discrete 5mm round diffused LED operates at a forward voltage of 2.1V with a test current of 20mA and delivers 60mcd luminous intensity at a 40° viewing angle. The component is currently in active production status with 743 units available in inventory. Equivalent and substitute parts are identified based on matching electrical characteristics, mechanical form factor compatibility, and optical performance parameters within acceptable tolerances for green LED indication circuits.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 333VGD are identified based on the following critical parameters that determine functional compatibility:

Electrical Compatibility Criteria:

• Forward voltage (Vf) within 0.1V tolerance of the main part (2.1V ± 0.1V acceptable range: 2.0V to 2.2V)
• Test current matching at 20mA
• Wavelength - Dominant within the green spectrum range (565nm to 575nm)

Mechanical Compatibility Criteria:

• Lens size: 5mm diameter form factor
• Mounting type: Through Hole radial configuration
• Package / Case: Radial
• Height compatibility for PCB assembly constraints

Optical Performance Criteria:

• Lens transparency: Diffused
• Color: Green
• Millicandela rating: Minimum 40mcd for indication applications

The substitute part WP7113SGD from Kingbright meets these criteria with compatible electrical characteristics (2.2V Vf, 20mA test current), matching mechanical form factor (5mm T-1 3/4 through-hole radial), and acceptable optical performance (40mcd, diffused green lens, 568nm dominant wavelength).

Parameter Comparison

Engineering Selection Recommendations

Both the 333VGD and WP7113SGD are active production components suitable for green LED indication applications. Selection between these parts is based on the following engineering factors:

333VGD Selection Criteria:

• Higher luminous intensity (60mcd vs 40mcd) for applications requiring greater brightness
• Wider viewing angle (40° vs 30°) for broader visibility requirements
• Everlight Electronics manufacturer availability with 743 units in stock

WP7113SGD Selection Criteria:

• Kingbright manufacturer with significantly higher inventory availability (17035 units in stock)
• RoHS3 compliance explicitly stated
• REACH Unaffected status confirmed
• Moisture Sensitivity Level (MSL) 1 rating for unlimited shelf life
• Suitable for applications where 40mcd brightness and 30° viewing angle meet functional requirements

Both parts operate within compatible electrical parameters (2.1V to 2.2V forward voltage range) and share identical through-hole radial mounting configuration. Component selection should be based on inventory availability, brightness requirements, and viewing angle specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Can WP7113SGD directly replace 333VGD in existing PCB designs?

A: Yes. Both components use identical through-hole radial mounting with 5mm lens diameter and compatible lead spacing. No PCB layout modifications are required. Forward voltage difference (2.1V vs 2.2V) is within standard LED circuit tolerance and does not require resistor recalculation for typical 20mA test current applications.

Q: What is the brightness difference between these two parts?

A: The 333VGD delivers 60mcd while WP7113SGD delivers 40mcd. This 33% brightness difference is significant for applications with strict luminous intensity requirements. Verify that the target application can function with 40mcd before substituting to WP7113SGD.

Q: Are there viewing angle considerations for substitution?

A: Yes. The 333VGD has a 40° viewing angle while WP7113SGD has a 30° viewing angle. The narrower viewing angle of WP7113SGD may limit visibility in applications requiring wide-angle indication. Confirm viewing angle requirements before substitution.

Q: What is the wavelength difference between these parts?

A: The 333VGD has a dominant wavelength of 571nm while WP7113SGD is 568nm. Both fall within the green spectrum range and are visually indistinguishable to the human eye. No functional difference exists for standard indication applications.

Q: Are there compliance or certification differences?

A: WP7113SGD explicitly lists RoHS3 compliance, REACH Unaffected status, and MSL 1 rating. These certifications should be verified for the 333VGD if regulatory compliance is a requirement for your application.

Q: What is the height difference and does it matter?

A: The 333VGD maximum height is 8.90mm while WP7113SGD is 8.60mm. This 0.30mm difference is negligible for standard through-hole PCB assembly and does not affect component placement or clearance in typical applications.

Q: Which part should I choose for new designs?

A: Selection depends on application-specific requirements. Choose 333VGD for higher brightness (60mcd) and wider viewing angle (40°). Choose WP7113SGD for superior inventory availability and explicit compliance certifications. Both are active production components suitable for long-term supply chain planning.
