LED Yellow Diffused Rectangular 2mm x 5mm Through-Hole 4306D17 Equivalent & Substitute Parts

Part Overview

The 4306D17 is a yellow diffused rectangular LED indicator manufactured by Visual Communications Company (VCC), designed for through-hole mounting applications. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing production, maintenance, and design continuity. The 4306D17 operates at 2.1V forward voltage with a 20mA test current, delivering 4 millicandela brightness through a diffused lens with a 100-degree viewing angle. Substitute parts must maintain electrical compatibility while meeting mechanical and optical specifications for direct board-level replacement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 4306D17 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Electrical Parameters: Forward voltage (Vf) of 2.1V, test current of 20mA, and peak wavelength of 585nm establish the electrical operating point and optical output characteristics.

Mechanical Parameters: Through-hole mounting type, radial package configuration, and rectangular 2mm x 5mm lens dimensions ensure physical compatibility with existing printed circuit board layouts and component footprints.

Optical Parameters: Yellow color, diffused lens transparency, and rectangle with flat top lens style maintain visual indication consistency and light distribution characteristics.

Compliance Parameters: ROHS3 compliance and EAR99 ECCN classification are mandatory for regulatory and export requirements.

Substitute parts are grouped into two categories:

Direct Substitutes (Electrical & Optical Match): Parts maintaining identical or equivalent millicandela ratings (4mcd) and viewing angles (100° or greater) with matching forward voltage and wavelength specifications.

Compatible Substitutes (Enhanced Specifications): Parts with superior optical performance (higher millicandela or wider viewing angle) while maintaining electrical compatibility and mechanical form factor.

Parameter Comparison

Engineering Selection Recommendations

MV53123E4R0 (Everlight Electronics): This part provides direct electrical and optical equivalence to the 4306D17, maintaining 4mcd brightness and 100-degree viewing angle with identical 2.1V forward voltage and 585nm peak wavelength. The MV53123E4R0 is currently in active production status with 813 pieces in stock inventory. Height specification of 7.80mm is within acceptable tolerance relative to the original 7.49mm. Moisture sensitivity level of MSL 1 (Unlimited) provides superior environmental stability compared to the original MSL 2 specification. ROHS3 compliance and EAR99 classification match regulatory requirements.

SSL-LX2573YD (Lumex Opto/Components): This part offers enhanced optical performance with 10mcd brightness and 110-degree viewing angle while maintaining 2.1V forward voltage and 585nm peak wavelength compatibility. The SSL-LX2573YD is actively produced with 851 pieces in stock. Height of 7.00mm is lower than the original specification, providing improved clearance in space-constrained applications. MSL 1 rating and ROHS3 compliance meet all regulatory requirements. The increased brightness and wider viewing angle make this suitable for applications requiring improved visibility.

WP113YDT (Kingbright): This part maintains 4mcd brightness and provides 110-degree viewing angle with 2.1V forward voltage. Peak wavelength of 590nm represents a 5nm shift from the original 585nm specification, remaining within the yellow LED spectrum range. The WP113YDT is actively produced with 3532 pieces in stock, offering the highest inventory availability. Height of 7.00mm and MSL 1 rating provide dimensional and environmental advantages. ROHS3 compliance and EAR99 classification satisfy regulatory requirements.

All three substitute parts are ROHS3 compliant and carry EAR99 ECCN classification, matching the original part's regulatory status. Selection should be based on specific application requirements regarding brightness level, viewing angle, and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the MV53123E4R0 be used as a direct replacement for the 4306D17?

A: Yes. The MV53123E4R0 maintains identical electrical specifications (2.1V forward voltage, 20mA test current), optical output (4mcd, 585nm peak wavelength), and mechanical form factor (rectangular 2mm x 5mm diffused lens, through-hole radial package). The 7.80mm height is within acceptable tolerance of the original 7.49mm specification.

Q: What is the difference between the SSL-LX2573YD and the original 4306D17?

A: The SSL-LX2573YD provides enhanced optical performance with 10mcd brightness compared to 4mcd, and a 110-degree viewing angle compared to 100 degrees. Electrical specifications (2.1V, 20mA, 585nm) remain identical. The lower height of 7.00mm may provide advantages in space-constrained designs. These differences do not prevent substitution in applications where increased brightness or wider viewing angle is acceptable.

Q: Why does the WP113YDT have a different peak wavelength (590nm vs 585nm)?

A: The 5nm wavelength difference falls within the yellow LED spectrum and does not significantly alter the visual appearance or functional performance of the indicator. Both wavelengths are classified as yellow and maintain compatibility with standard yellow LED applications. The difference is within normal manufacturing tolerances for LED components.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All three substitute parts (MV53123E4R0, SSL-LX2573YD, and WP113YDT) are ROHS3 compliant and carry EAR99 ECCN classification, matching the regulatory status of the original 4306D17.

Q: What is the significance of the Moisture Sensitivity Level (MSL) difference?

A: The original 4306D17 carries MSL 2 (1 Year), while all substitute parts carry MSL 1 (Unlimited). MSL 1 indicates superior moisture resistance and longer shelf life without requiring special storage conditions. This represents an improvement over the original specification.

Q: Which substitute part has the highest inventory availability?

A: The WP113YDT from Kingbright has the highest inventory with 3532 pieces in stock, compared to 813 pieces for MV53123E4R0 and 851 pieces for SSL-LX2573YD.

Q: Can the SSL-LX2573YD be used in applications requiring the exact 4mcd brightness of the original part?

A: The SSL-LX2573YD provides 10mcd brightness, which is 2.5 times brighter than the original 4mcd specification. In applications with strict brightness requirements, this increased output may not be suitable. The MV53123E4R0 or WP113YDT should be selected for equivalent brightness levels.

Q: Are there any height clearance concerns with the substitute parts?

A: The MV53123E4R0 has a maximum height of 7.80mm, which is 0.31mm taller than the original 7.49mm. The SSL-LX2573YD and WP113YDT both have maximum heights of 7.00mm, which is 0.49mm shorter than the original. Height differences should be evaluated against specific PCB layout and enclosure constraints.
