Dialight 5520822 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5520822 is a dual-level green LED circuit board indicator designed for through-hole, right-angle mounting applications. This component features a 5mm diffused, tinted lens with domed top and operates at 2.2V with 20mA current consumption. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations. Active substitute options are available from both the original manufacturer and qualified cross-reference suppliers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5520822 is determined by strict alignment of the following critical parameters:

• Electrical Compatibility: Voltage rating (2.2V), current consumption (20mA), and configuration (2 High dual-level)
• Optical Characteristics: Color (green), wavelength range (563nm nominal), and lens type (diffused, tinted)
• Mechanical Compatibility: Mounting type (through-hole, right-angle), lens size (5mm, T-1 3/4), and lens style (round with domed top)
• Environmental & Regulatory: MSL rating (1 - Unlimited), REACH compliance, and ECCN classification

Two substitute parts meet these criteria:

1. 5520822F (Dialight) - Direct manufacturer substitute with identical electrical and optical specifications. Active product status with RoHS3 compliance.
2. SSF-LXHM250GGD (Lumex Opto/Components Inc.) - Cross-manufacturer equivalent with matching core electrical parameters and mechanical form factor. Minor optical variations within acceptable tolerance.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): The Dialight 5520822F is the primary substitute. As an active product from the original manufacturer, it maintains identical electrical and optical specifications to the obsolete 5520822. RoHS3 compliance ensures regulatory alignment with modern manufacturing standards. This part is suitable for direct board-level substitution without circuit modification.

For Cross-Manufacturer Substitution: The Lumex Opto/Components Inc. SSF-LXHM250GGD provides functional equivalence with minor parameter variations. The wavelength peak differs by 2nm (565nm vs. 563nm), millicandela rating is 4mcd lower (30mcd vs. 34mcd), and viewing angle is 10° wider (60° vs. 50°). These variations remain within typical LED tolerance ranges for general indicator applications. RoHS3 compliance and identical electrical ratings ensure circuit compatibility. This option is suitable when supply constraints or cost considerations apply.

Both substitutes maintain identical mounting form factor, voltage/current specifications, and environmental ratings, enabling direct mechanical and electrical interchange.

Frequently Asked Questions (FAQ)

Q: Can the 5520822F be used as a direct replacement for the obsolete 5520822? A: Yes. The 5520822F is a direct manufacturer substitute with identical electrical specifications (2.2V, 20mA), optical characteristics (563nm wavelength, 34mcd, 50° viewing angle), and mechanical form factor (5mm through-hole, right-angle mount). No circuit modifications are required.

Q: What are the key differences between the Dialight 5520822F and Lumex SSF-LXHM250GGD? A: Both parts share identical voltage (2.2V), current (20mA), configuration (2 High), and mounting type (through-hole, right-angle). The Lumex part has a 2nm higher wavelength peak (565nm vs. 563nm), 4mcd lower brightness (30mcd vs. 34mcd), and a 10° wider viewing angle (60° vs. 50°). These differences are within standard LED tolerance ranges.

Q: Are both substitute parts RoHS compliant? A: Yes. Both the Dialight 5520822F and Lumex SSF-LXHM250GGD are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: What is the MSL rating for these parts? A: All three parts (5520822, 5520822F, and SSF-LXHM250GGD) have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Can the Lumex SSF-LXHM250GGD be used in applications requiring the exact 34mcd brightness of the original 5520822? A: The Lumex part provides 30mcd, which is 4mcd lower than the original specification. For applications with strict brightness requirements, the Dialight 5520822F is the preferred choice. For general indicator applications, the 30mcd output is typically acceptable.

Q: Are there any packaging differences between these parts? A: The Dialight 5520822 is packaged individually, while both 5520822F and SSF-LXHM250GGD are supplied in bulk packaging. Verify packaging requirements for your procurement process.
