Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5GW are identified based on strict compatibility criteria within the through-hole green LED category. The following parameters must align for valid substitution:

Mandatory Alignment Parameters:

• Lens Size: 5mm, T-1 3/4
• Mounting Type: Through Hole
• Color: Green
• Wavelength - Peak: 568nm
• Viewing Angle: 45°
• Lens Transparency: Diffused
• Lens Style: Round with Domed Top

Allowable Variation Parameters:

• Voltage - Forward (Vf): Within circuit design tolerance
• Millicandela Rating: Application-dependent brightness requirements
• Height (Max): Within PCB assembly clearance limits
• Lens Color: May vary while maintaining optical function
• Product Status: Active status preferred for ongoing availability

The Bivar Inc. 5GD meets these criteria and qualifies as a direct substitute for the obsolete 5GW.

Parameter Comparison

Engineering Selection Recommendations

The Bivar Inc. 5GD is the qualified substitute for the obsolete 5GW based on the following engineering criteria:

Product Status Advantage: The 5GD holds Active product status, ensuring continued manufacturing availability and supply chain reliability. The 5GW is classified as Obsolete, necessitating substitution for new designs and ongoing production support.

Compliance and Certification: Both parts share identical HTSUS classification (8541.41.0000) and ECCN designation (EAR99). The 5GD carries RoHS3 Compliance certification, meeting current environmental and regulatory standards. Both components maintain Moisture Sensitivity Level 1 (Unlimited), indicating no special handling requirements.

Electrical Compatibility: The forward voltage differential of 0.1V (5GW: 2.2V vs. 5GD: 2.1V) is within acceptable tolerance for standard current-limiting resistor circuits. Both parts operate at identical test current (20mA) and share the same wavelength specification (568nm).

Mechanical Compatibility: Both components feature identical lens size (5mm, T-1 3/4), mounting type (Through Hole), and viewing angle (45°). Height variation of 0.30mm (5GW: 8.80mm vs. 5GD: 8.50mm) is negligible for standard PCB assembly applications.

Brightness Consideration: The 5GD provides 25mcd compared to the 5GW's 65mcd. This reduced brightness rating requires application-level assessment. For indication-only applications with standard ambient lighting, the 5GD brightness is sufficient. For high-visibility or outdoor applications, brightness reduction may impact performance.

Visual Appearance Difference: The 5GW features a white diffused lens, while the 5GD features a green diffused lens. This difference affects the visual appearance of the illuminated LED but does not impact electrical function or optical wavelength characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 5GD directly replace the 5GW in existing PCB designs?

A: Yes, for most applications. Both parts share identical mechanical footprints (5mm, T-1 3/4 through-hole), mounting compatibility, and electrical operating points (20mA test current). The 0.1V forward voltage difference requires no circuit redesign for standard resistor-based current limiting. Verify that the reduced brightness (25mcd vs. 65mcd) meets your application's visibility requirements.

Q: What is the impact of the lens color difference (white vs. green)?

A: The lens color affects visual appearance only. The white lens on the 5GW provides a neutral appearance when illuminated, while the green lens on the 5GD provides a green-tinted appearance. Both lenses are diffused and transmit the same 568nm wavelength green light. Select based on aesthetic requirements for your application.

Q: Is the 0.30mm height difference significant?

A: No. The height variation (5GW: 8.80mm vs. 5GD: 8.50mm) is negligible for standard PCB assembly. This difference does not affect mounting, clearance, or functional performance in typical through-hole applications.

Q: Why is the 5GD brightness lower than the 5GW?

A: The 5GD is rated at 25mcd while the 5GW is rated at 65mcd. This is a design characteristic of the substitute part. For indication applications with standard ambient lighting, 25mcd provides adequate visibility. For high-brightness or outdoor visibility requirements, assess whether the reduced rating meets your specific application needs.

Q: Are there any compliance or regulatory differences?

A: No. Both parts share identical HTSUS classification (8541.41.0000) and ECCN designation (EAR99). The 5GD carries RoHS3 Compliance certification, meeting current environmental standards. Both maintain Moisture Sensitivity Level 1 (Unlimited).

Q: What is the advantage of using the 5GD over the 5GW?

A: The 5GD is actively manufactured (Active product status), ensuring reliable long-term availability. The 5GW is Obsolete, making future procurement difficult or impossible. For new designs and ongoing production, the 5GD provides supply chain continuity.

Q: Can I use the 5GD in applications requiring the 5GW's higher brightness?

A: No. If your application specifically requires 65mcd brightness, the 5GD's 25mcd rating is insufficient. Evaluate alternative green LED options with higher brightness ratings, or confirm that your application can function with reduced brightness levels.
