Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Color and Wavelength: Yellow color with peak wavelength 585nm (±5nm tolerance acceptable)
• Voltage - Forward (Vf): 2.0V to 2.1V typical operating range
• Current - Test: 10mA to 20mA test current range
• Lens Size: 3mm diameter T-1 or equivalent form factor
• Mounting Type: Through-hole radial configuration
• Lens Transparency: Diffused lens type
• Compliance: RoHS3 compliant, REACH unaffected, MSL 1

Parts are grouped into two categories:

Group A - Direct Yellow LED Substitutes (Same Color, Compatible Electrical Parameters)

• VCC 4303F7
• Broadcom HLMP-1401
• Broadcom HLMP-1401-D0002
• Broadcom HLMP-1401-E0000
• Lumex SSL-LX3052YD

Group B - Alternative Color (Not Recommended for Direct Substitution)

• Broadcom HLMP-K401 (Orange, different wavelength and forward voltage)

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Yellow Color, Compatible Electrical Parameters)

VCC 4303F7 and Lumex SSL-LX3052YD are the closest electrical equivalents. Both maintain 2.1V forward voltage and 585nm peak wavelength. VCC 4303F7 offers 10mcd brightness with 55° viewing angle and 6.40mm height. Lumex SSL-LX3052YD provides higher brightness (15mcd) with wider viewing angle (80°) but operates at 20mA test current and reduced height (5.25mm). Both are RoHS3 compliant and active products with full inventory availability.

Broadcom HLMP-1401 series (HLMP-1401, HLMP-1401-D0002, HLMP-1401-E0000) operate at 2.0V forward voltage with 583nm peak wavelength. These parts are electrically compatible within standard LED tolerance ranges. Brightness varies across the series (2.2mcd to 5.7mcd). HLMP-1401-D0002 is supplied in cut tape packaging, while HLMP-1401 and HLMP-1401-E0000 are bulk packaged. All three are active products with substantial inventory.

Not Recommended for Direct Substitution

Broadcom HLMP-K401 is an orange LED (602nm wavelength, 1.9V forward voltage) and does not meet the yellow color specification of the original part. This part is listed in the original substitute list but represents a different functional category.

All recommended substitutes maintain RoHS3 compliance, REACH unaffected status, and MSL 1 moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can I substitute the Dialight 5219211F with a Broadcom HLMP-1401 series LED?

A: Yes. The HLMP-1401 series maintains yellow color, 585nm peak wavelength region, and 2.0V forward voltage within acceptable LED operating tolerances. All variants (HLMP-1401, HLMP-1401-D0002, HLMP-1401-E0000) are electrically compatible. Brightness varies by part number (2.2mcd to 5.7mcd), which may affect visual indication intensity in your application.

Q: What is the difference between bulk and cut tape packaging for HLMP-1401 variants?

A: HLMP-1401 and HLMP-1401-E0000 are supplied in bulk packaging suitable for manual assembly or tube feeding. HLMP-1401-D0002 is supplied in cut tape (CT) packaging for automated pick-and-place assembly. Electrical and optical specifications are identical across packaging types.

Q: Is the Lumex SSL-LX3052YD a suitable replacement?

A: Yes. The SSL-LX3052YD maintains 2.1V forward voltage and 585nm peak wavelength. It provides higher brightness (15mcd versus 8.7mcd) and wider viewing angle (80° versus 60°). The test current is 20mA instead of 10mA, and the maximum height is 5.25mm versus 6.00mm. These differences are within mechanical and electrical compatibility for through-hole mounting applications.

Q: Why is the Broadcom HLMP-K401 listed as a substitute if it is orange?

A: The HLMP-K401 is an orange LED (602nm wavelength) and does not meet the yellow color requirement. It is not recommended for direct substitution in applications requiring yellow indication. This part appears in the original substitute list but represents a different functional category.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (VCC 4303F7, Broadcom HLMP-1401 series, Lumex SSL-LX3052YD, and Broadcom HLMP-K401) are RoHS3 compliant and REACH unaffected. All maintain MSL 1 moisture sensitivity rating.

Q: What is the viewing angle difference between the original part and substitutes?

A: The Dialight 5219211F has a 60° viewing angle. VCC 4303F7 has 55°, Broadcom HLMP-1401 series has 60°, and Lumex SSL-LX3052YD has 80°. Wider viewing angles provide better visibility from off-axis positions but may reduce peak brightness in the forward direction.

Q: Can I use the Dialight 5219211F and its substitutes interchangeably in the same circuit?

A: Yes, provided your circuit design accommodates the brightness and forward voltage variations. The original part operates at 8.7mcd with 2.1V. Broadcom HLMP-1401 series operates at 2.0V with lower brightness (2.2mcd to 5.7mcd). Lumex SSL-LX3052YD operates at 2.1V with higher brightness (15mcd). Adjust current-limiting resistor values if brightness differences are critical to your application.
