Dialight 5505305F LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5505305F is a 5mm yellow LED circuit board indicator designed for through-hole, right-angle mounting applications. This component features a diffused, tinted lens with a domed top and operates at 2.2V with a 20mA current rating, delivering 34mcd of luminous intensity. The part is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the 5505305F are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Color: Yellow (585nm peak wavelength)
• Configuration: Single LED
• Mounting Type: Through Hole, Right Angle
• Lens Size: 5mm form factor
• Voltage Range: 2.1V to 2.2V
• RoHS3 Compliance

Substitution Logic: The 5505305F has two identified substitutes that maintain the core functional requirements of a yellow, right-angle mounted 5mm LED indicator. Substitutes are grouped by their electrical and mechanical alignment with the original component specifications.

Parameter Comparison

Engineering Selection Recommendations

Dialight 5502305F (MFR Recommended Substitute): This Dialight component maintains manufacturer continuity and ROHS3 compliance. The 5502305F operates at 2.1V with a 10mA current rating and delivers 6.3mcd. The reduced current and luminous intensity represent a lower-power alternative within the same manufacturer's product line. Selection of this part is appropriate when lower power consumption is acceptable and the reduced brightness meets application requirements.

Lumex Opto/Components Inc. SSF-LXH100MYD (Similar Substitute): This cross-manufacturer substitute maintains the 20mA current rating and 34mcd brightness specification of the original 5505305F, providing closer electrical performance matching. Operating at 2.1V with a 60° viewing angle and diffused, tinted lens, this component offers active product status and ROHS3 compliance. The SSF-LXH100MYD is suitable for applications requiring brightness and current characteristics aligned with the original design.

Both substitutes maintain the critical through-hole, right-angle mounting configuration and 5mm form factor required for PCB integration.

Frequently Asked Questions (FAQ)

Q: Can the 5502305F directly replace the 5505305F in all applications? A: The 5502305F operates at lower current (10mA vs. 20mA) and lower brightness (6.3mcd vs. 34mcd). Direct replacement is possible only if the application can tolerate reduced luminous intensity and lower power draw. Circuit design modifications may be necessary to accommodate the different electrical characteristics.

Q: What is the primary difference between the two substitute options? A: The Dialight 5502305F is a lower-power variant from the same manufacturer, while the Lumex SSF-LXH100MYD maintains the original 20mA current and 34mcd brightness specifications. The Lumex option provides closer electrical performance matching to the obsolete 5505305F.

Q: Are both substitutes compatible with the original PCB mounting footprint? A: Both substitutes maintain through-hole, right-angle mounting configuration and 5mm form factor. Physical compatibility with the original PCB layout is preserved. Verify specific lead spacing and mounting hole dimensions against your PCB design.

Q: Do the substitutes maintain the same compliance certifications? A: Yes, both the Dialight 5502305F and Lumex SSF-LXH100MYD are ROHS3 compliant and REACH unaffected, matching the compliance profile of the original 5505305F.

Q: What viewing angle differences exist between the options? A: The original 5505305F and Dialight 5502305F both feature a 50° viewing angle. The Lumex SSF-LXH100MYD provides a wider 60° viewing angle, which may be advantageous in applications requiring broader light distribution.
