Dialight 5219211 LED Yellow Diffused 3MM Through Hole - Equivalent & Substitute Parts

Part Overview

The Dialight 5219211 is a yellow diffused 3mm through-hole LED designed for indication applications. It operates at 2.1V forward voltage with a 10mcd brightness rating and 60° viewing angle. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain compatibility across electrical characteristics, mechanical form factor, and mounting specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5219211 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Color: Yellow
• Lens Transparency: Diffused
• Mounting Type: Through Hole
• Lens Size: 3mm or T-1 package equivalent
• Voltage - Forward (Vf): 2.0V to 2.1V range
• Wavelength - Peak: 583nm to 590nm range

Secondary Considerations:

• Millicandela Rating: Minimum 2.2mcd (substitutes may vary from 2.2mcd to 15mcd)
• Current - Test: 10mA to 20mA operating range
• Viewing Angle: 40° to 60° acceptable range
• Height (Max): 4.60mm to 6.40mm acceptable range
• Product Status: Active status preferred for long-term availability
• RoHS Compliance: ROHS3 compliant substitutes recommended for new designs

Non-Substitutable Parts:

• HLMP-K401 and HLMP-K401-E0002 are orange LEDs (602nm wavelength) and do not qualify as direct substitutes despite similar electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Preferred): The Dialight 5219211F is the primary substitute. It maintains identical forward voltage (2.1V), wavelength (585nm), and mechanical dimensions (6.00mm height). The part is active and ROHS3 compliant. Test current is reduced to 10mA, resulting in slightly lower brightness (8.7mcd vs. 10mcd), which is acceptable for most indication applications.

Alternative Substitutes (Yellow LED, Active Status):

• VCC 4303F7: Maintains 10mcd brightness and 2.1V forward voltage. Height tolerance is 6.40mm maximum. Viewing angle is 55° versus 60° on the original part.
• Broadcom HLMP-1401 series (HLMP-1401, HLMP-1401-D0002, HLMP-1401-E0000): All are active, ROHS3 compliant yellow LEDs with 2V forward voltage and 60° viewing angle. Brightness varies from 2.2mcd to 5.7mcd. These parts operate at lower brightness levels and are suitable for applications where reduced luminous intensity is acceptable.
• Lumex SSL-LX3044YD: Provides highest brightness (15mcd) at 2.1V forward voltage and 585nm wavelength. Viewing angle is narrower at 40°. Height is reduced to 4.60mm, which may affect mechanical fit in some applications.

Compliance Consideration: All recommended substitutes are ROHS3 compliant, addressing the non-compliance status of the obsolete 5219211. New designs should prioritize ROHS3 compliant alternatives.

Frequently Asked Questions (FAQ)

Q: Can HLMP-K401 or HLMP-K401-E0002 be used as substitutes? A: No. These are orange LEDs (602nm wavelength) with 1.9V forward voltage. They do not meet the yellow color specification (585nm) required for the 5219211 application.

Q: What is the difference between 5219211 and 5219211F? A: The 5219211F is the active production variant of the same base design. Both operate at 2.1V and 585nm wavelength with identical mechanical dimensions. The 5219211F is ROHS3 compliant and operates at 10mA test current versus 20mA for the original part, resulting in 8.7mcd versus 10mcd brightness.

Q: Are there brightness differences between substitutes? A: Yes. Brightness varies from 2.2mcd (HLMP-1401) to 15mcd (SSL-LX3044YD). The original 5219211 is rated at 10mcd. Selection depends on application requirements. Lower brightness parts reduce power consumption; higher brightness parts improve visibility in bright environments.

Q: What packaging options are available? A: Substitutes are available in Bulk, Cut Tape (CT), and Tape & Reel (TR) packaging. Packaging selection depends on production volume and assembly process requirements.

Q: Do all substitutes have the same viewing angle? A: No. Viewing angles range from 40° (SSL-LX3044YD) to 60° (5219211F, HLMP-1401 series, 4303F7). The original 5219211 specifies 60°. Narrower viewing angles concentrate light intensity; wider angles distribute light more broadly.

Q: Are there height differences that affect mechanical fit? A: Yes. Heights range from 4.60mm (SSL-LX3044YD) to 6.40mm (4303F7). The original 5219211 is 6.00mm. Verify PCB clearance and mechanical constraints before selecting a substitute with different height specifications.

Q: Which substitute has the best long-term availability? A: All recommended substitutes carry active product status. Broadcom HLMP-1401 series parts show the highest inventory levels (3,100 to 37,482 units), indicating strong availability. Dialight 5219211F and Lumex SSL-LX3044YD also maintain substantial inventory.
