Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 4301H5/5 are identified based on strict alignment with the following critical parameters:

Electrical Compatibility Criteria:

• Forward voltage (Vf): 2.2V
• Test current: 20mA
• Peak wavelength: 565nm (green spectrum)
• Millicandela rating: 20mcd
• Viewing angle: 60°

Mechanical Compatibility Criteria:

• Lens size: 5mm, T-1 3/4
• Lens transparency: Diffused
• Mounting type: Through Hole
• Package type: Radial
• Height (Max): 8.60-8.61mm

Regulatory & Environmental Criteria:

• RoHS3 Compliance
• MSL 1 (Unlimited)
• REACH Unaffected status
• ECCN: EAR99

Parts meeting all electrical, mechanical, and regulatory parameters are classified as direct substitutes. Parts meeting electrical and regulatory parameters with minor wavelength variations within the green spectrum are classified as similar substitutes.

Parameter Comparison

Engineering Selection Recommendations

WP57GGD (Kingbright) - Direct Substitute

The Kingbright WP57GGD provides complete parameter alignment with the 4301H5/5 across all electrical, mechanical, and regulatory specifications. Forward voltage, test current, millicandela rating, viewing angle, and physical dimensions match exactly. The part maintains Active product status, ensuring long-term availability and supply chain continuity. RoHS3 compliance and MSL 1 rating are identical. This part is suitable for direct replacement in existing designs and new production runs.

SSL-LX5093GGD (Lumex Opto/Components Inc.) - Similar Substitute

The Lumex SSL-LX5093GGD shares peak wavelength (565nm) and mounting characteristics with the 4301H5/5. The part is RoHS3 compliant with MSL 1 rating. However, specific electrical parameters (forward voltage, test current, millicandela rating, and viewing angle) are not provided in available documentation. This part maintains Active product status. Selection of this substitute requires confirmation of electrical parameter compatibility through manufacturer datasheets prior to implementation.

Frequently Asked Questions (FAQ)

Q: Can the WP57GGD replace the 4301H5/5 in existing circuit designs?

A: Yes. The WP57GGD matches all specified electrical parameters (2.2V forward voltage, 20mA test current, 20mcd brightness, 60° viewing angle) and mechanical specifications (5mm T-1 3/4 diffused lens, through-hole radial package, 8.60mm height). No circuit modifications are required.

Q: What is the primary reason for finding substitutes for the 4301H5/5?

A: The 4301H5/5 is classified as "Not For New Designs," indicating the manufacturer is discontinuing or has discontinued active support. Identifying active equivalent parts ensures supply chain continuity for production and maintenance applications.

Q: Are there differences in physical dimensions between the 4301H5/5 and WP57GGD?

A: Maximum height differs by 0.01mm (4301H5/5: 8.61mm; WP57GGD: 8.60mm). This variation is within standard manufacturing tolerances and does not affect PCB layout or mechanical fit in standard through-hole applications.

Q: What parameters must match for a part to be considered a direct substitute?

A: Direct substitutes must match forward voltage (2.2V), test current (20mA), peak wavelength (565nm), millicandela rating (20mcd), viewing angle (60°), lens size (5mm T-1 3/4), lens transparency (diffused), mounting type (through-hole), package type (radial), and regulatory compliance (RoHS3, MSL 1).

Q: Why are specific electrical parameters not provided for the SSL-LX5093GGD?

A: The available product data for the SSL-LX5093GGD does not include forward voltage, test current, millicandela rating, or viewing angle specifications. Manufacturer datasheets must be consulted to confirm compatibility with the 4301H5/5 electrical requirements.

Q: Are both substitute parts RoHS3 compliant?

A: Yes. Both the WP57GGD and SSL-LX5093GGD are RoHS3 compliant with MSL 1 (Unlimited) rating, matching the environmental and regulatory status of the 4301H5/5.
