LED GREEN DIFF RECT 2MMX5MM T/H - 4306D15 Equivalent & Substitute Parts

Part Overview

The 4306D15 is a green diffused rectangular LED indicator manufactured by Visual Communications Company (VCC), designed for through-hole mounting applications. This component is classified as obsolete, which necessitates identification of equivalent substitute parts for ongoing design support and procurement continuity. The 4306D15 operates at 2.2V forward voltage with a 20mA test current and delivers 4 millicandela brightness in a 5.03mm x 2.00mm rectangular lens format with 100° viewing angle.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 4306D15 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Color: Green
• Lens Transparency: Diffused
• Lens Style: Rectangle with Flat Top
• Lens Size: 5.00mm x 2.00mm (±0.20mm tolerance acceptable)
• Voltage - Forward (Vf): 2.2V
• Current - Test: 20mA
• Mounting Type: Through Hole
• Package / Case: Radial

Acceptable Variation Parameters:

• Millicandela Rating: 4mcd to 10mcd (brightness variation within indicator application tolerance)
• Wavelength - Peak: 562nm to 568nm (green spectrum consistency)
• Viewing Angle: 100° to 110° (minor angular variation acceptable for indicator applications)
• Height Maximum: 7.00mm to 7.80mm (PCB clearance dependent on design)

All substitute parts listed below meet these criteria and are electrically and mechanically compatible with the 4306D15 in standard indicator circuit applications.

Parameter Comparison

Engineering Selection Recommendations

For Active Production and New Designs:

SSL-LX2573GD (Lumex Opto/Components Inc.) and WP113GDT (Kingbright) are recommended as primary substitutes. Both parts carry Active product status, ensuring long-term availability and supply chain stability. Both are ROHS3 compliant and feature MSL 1 (Unlimited) moisture sensitivity rating, providing superior storage and handling characteristics compared to the obsolete 4306D15.

SSL-LX2573GD offers the highest brightness rating at 10mcd with a 110° viewing angle and 7.00mm maximum height, suitable for applications requiring enhanced visibility or wider angular distribution. WP113GDT provides 5mcd brightness with equivalent 110° viewing angle and 7.00mm height, offering a balanced alternative with established supply availability.

For Legacy System Support:

MV54123 (onsemi) maintains electrical and mechanical equivalence to the 4306D15 with identical 4mcd brightness and 100° viewing angle. However, MV54123 carries Obsolete product status, limiting its suitability for long-term procurement. This part is appropriate only for short-term legacy system repairs where exact performance matching is required.

Compliance Considerations:

All substitute parts are REACH Unaffected and classified under ECCN EAR99 and HTSUS 8541.41.0000, matching the regulatory classification of the original 4306D15. SSL-LX2573GD and WP113GDT provide enhanced compliance documentation through ROHS3 certification.

Frequently Asked Questions (FAQ)

Q: Can SSL-LX2573GD replace 4306D15 in existing circuit designs?

A: Yes. SSL-LX2573GD is electrically and mechanically compatible. Both operate at 2.2V forward voltage with 20mA test current. The higher brightness rating (10mcd vs. 4mcd) and wider viewing angle (110° vs. 100°) represent performance enhancements rather than incompatibilities. PCB layout remains unchanged due to identical lens size (5.00mm x 2.00mm) and radial through-hole mounting.

Q: What is the difference between WP113GDT and SSL-LX2573GD?

A: Both parts meet the core substitution criteria. WP113GDT delivers 5mcd brightness with 110° viewing angle and 7.00mm height. SSL-LX2573GD delivers 10mcd brightness with 110° viewing angle and 7.00mm height. Selection depends on required brightness level for the specific indicator application. Both are Active products with equivalent availability.

Q: Why is MV54123 listed if it is obsolete?

A: MV54123 is included for reference as a direct electrical and mechanical equivalent to the 4306D15, maintaining identical 4mcd brightness and 100° viewing angle. However, its Obsolete status makes it unsuitable for new designs or long-term procurement. It is listed only for legacy system documentation purposes.

Q: Are there height clearance concerns when substituting with SSL-LX2573GD or WP113GDT?

A: Both substitute parts have 7.00mm maximum height, compared to 4306D15 at 7.49mm. This represents a 0.49mm reduction in height, eliminating any PCB clearance concerns. Designs with height constraints will benefit from this dimensional improvement.

Q: Do all substitute parts have the same moisture sensitivity rating?

A: No. The 4306D15 carries MSL 2 (1 Year) rating. SSL-LX2573GD and WP113GDT both carry MSL 1 (Unlimited) rating, indicating superior moisture resistance and extended storage capability without baking requirements. MV54123 also carries MSL 1 (Unlimited). This represents an improvement in handling and storage characteristics.

Q: What wavelength differences exist among these parts?

A: The 4306D15 has a peak wavelength of 562nm. All substitute parts (MV54123, SSL-LX2573GD, WP113GDT) have peak wavelengths of 565nm or 568nm. These variations fall within the green spectrum and are visually indistinguishable in indicator applications. No circuit modifications are required.

Q: Can these parts be used interchangeably in the same PCB assembly?

A: Yes. All parts share identical lens size (5.00mm x 2.00mm), radial through-hole mounting configuration, and forward voltage (2.2V). PCB footprints and circuit designs require no modification. Parts can be substituted without design changes.
