Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Dialight 5219208F are identified based on the following critical parameters that determine functional and mechanical compatibility:

• Color: Yellow (585nm wavelength)
• Voltage - Forward (Vf): 2.1V nominal
• Millicandela Rating: 60mcd
• Physical Form Factor: T-1 3/4 lens size
• Base Configuration: Midget Flange or equivalent through-hole mounting
• Compliance: ROHS3 Compliant, REACH Unaffected

The Lumex Opto/Components Inc. SSL-LX507F3YT meets these substitution criteria through matching electrical characteristics (2.1V forward voltage, 60mcd output, 585nm peak wavelength) and compatible physical dimensions (T-1 3/4 form factor). While the SSL-LX507F3YT uses radial through-hole mounting rather than midget flange base, the electrical performance and optical output remain equivalent for indicator light applications.

Parameter Comparison

Engineering Selection Recommendations

The Lumex Opto/Components Inc. SSL-LX507F3YT is an active substitute for the discontinued Dialight 5219208F. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent applications. The SSL-LX507F3YT delivers identical electrical performance (2.1V forward voltage, 60mcd output) and optical characteristics (585nm wavelength, yellow color) required for indicator light circuits.

Selection of the SSL-LX507F3YT requires mechanical evaluation of the mounting interface. The original Dialight part uses midget flange base configuration, while the Lumex substitute employs radial through-hole mounting. Circuit board layout and socket compatibility must be assessed to determine if mechanical adaptation is feasible for the target application.

Frequently Asked Questions (FAQ)

Q: Can the Lumex SSL-LX507F3YT directly replace the Dialight 5219208F without modification?

A: Electrical compatibility is confirmed through matching forward voltage (2.1V), millicandela rating (60mcd), and wavelength (585nm). Mechanical compatibility depends on the mounting interface. The Dialight uses midget flange base while the Lumex uses radial through-hole leads. Direct socket replacement is not possible without mechanical adaptation or circuit board modification.

Q: Are there compliance differences between these parts?

A: Both components are ROHS3 compliant and REACH unaffected. No compliance barriers exist for substitution in regulated applications.

Q: What is the viewing angle of the Lumex substitute?

A: The Lumex SSL-LX507F3YT has a 30° viewing angle. Verify this specification against the original application requirements, as viewing angle affects indicator visibility in the installed circuit.

Q: What is the test current for the Lumex substitute?

A: The Lumex SSL-LX507F3YT is rated at 20mA test current. Confirm that the circuit design accommodates this current specification.

Q: Why is the Dialight 5219208F discontinued?

A: Product discontinuation at DiGi Electronics indicates end-of-life status. The Lumex SSL-LX507F3YT remains in active production and is available in current inventory (708 pieces).
