Dialight 5505307004F LED Circuit Board Indicator Equivalent & Substitute Parts

Part Overview

The Dialight 5505307004F is a quad-wide yellow LED circuit board indicator featuring a 5mm diffused lens with domed top, designed for through-hole right-angle mounting. This component is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. The part operates at 2.2V with 20mA current consumption and delivers 34mcd brightness at a 50° viewing angle. Substitute parts must maintain compatibility with the electrical specifications, mechanical form factor, and mounting configuration of the original design.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5505307004F is determined by the following critical parameters:

Primary Compatibility Criteria:

• Configuration: 4 Wide (quad-wide LED array)
• Color: Yellow (x 4)
• Wavelength - Peak: 585nm
• Mounting Type: Through Hole, Right Angle
• Lens Size: 5mm, T-1 3/4 form factor

Secondary Compatibility Criteria:

• Voltage Rating: 2.1V to 2.2V range
• Current: 10mA to 20mA range
• Lens Type: Diffused
• Viewing Angle: 50° or greater

Substitutes are classified into two categories: manufacturer-recommended direct replacements and similar alternatives from other manufacturers. The manufacturer-recommended substitute (5502307004F) is the primary choice for direct replacement. Similar alternatives from other manufacturers (SSF-LXH400YD) provide functional equivalence when the recommended substitute is unavailable.

Parameter Comparison

Engineering Selection Recommendations

Dialight 5502307004F (Manufacturer-Recommended Substitute): This part is the primary replacement for the obsolete 5505307004F. Both components are from the same manufacturer and share identical configuration, color, wavelength, mounting type, and lens size specifications. The 5502307004F is currently in active production status, ensuring long-term availability. The part maintains ROHS3 compliance and REACH unaffected status. The voltage rating is compatible at 2.1V versus the original 2.2V, and current consumption is reduced to 10mA from 20mA, resulting in lower power dissipation. The brightness output is reduced to 6.3mcd from 34mcd; this difference must be evaluated against circuit design requirements.

Lumex Opto/Components Inc. SSF-LXH400YD (Similar Alternative): This part provides functional equivalence when the manufacturer-recommended substitute is unavailable. It matches the critical parameters of configuration, color, wavelength, lens size, and mounting type. The SSF-LXH400YD maintains the original 20mA current specification and operates at 2.1V. The component is in active production status and maintains ROHS3 compliance and REACH unaffected status. The lens type is specified as diffused with tint, which may affect color perception compared to the original diffused lens. Millicandela rating and viewing angle are not specified for this part; circuit performance validation is required before implementation.

Frequently Asked Questions (FAQ)

Q: Can the 5502307004F directly replace the 5505307004F in existing designs? A: The 5502307004F is mechanically and electrically compatible for through-hole right-angle mounting applications. The primary design consideration is the reduced brightness output (6.3mcd versus 34mcd). Circuits designed with brightness margin can accommodate this substitute. Voltage and current specifications are within acceptable ranges for most LED indicator applications.

Q: What are the key differences between the manufacturer-recommended and similar substitutes? A: The Dialight 5502307004F is the manufacturer-recommended option with documented specifications from the original manufacturer. The Lumex SSF-LXH400YD is a similar alternative from a different manufacturer that maintains the original 20mA current specification but has unspecified brightness and viewing angle parameters. The Dialight option is preferred when available due to complete specification documentation.

Q: Are there any compliance or certification differences between these parts? A: All three parts (original, manufacturer-recommended substitute, and similar alternative) are ROHS3 compliant, REACH unaffected, and carry the same ECCN and HTSUS classifications. No compliance barriers exist for substitution.

Q: How does the reduced current consumption of the 5502307004F affect circuit design? A: The 5502307004F operates at 10mA versus the original 20mA specification. This reduces power dissipation and may allow for higher series resistor values in current-limiting circuits. Existing circuit designs must be evaluated to confirm that the reduced current does not compromise brightness visibility requirements.

Q: What mounting considerations apply to these substitutes? A: All three parts are specified for through-hole right-angle mounting with 5mm, T-1 3/4 lens size. PCB footprint compatibility is maintained across all substitutes. No mechanical redesign is required for mounting.
