Parameter Comparison

Engineering Selection Recommendations

LTL-433HR (Lite-On Inc.): This part maintains active product status and ROHS3 compliance. It matches all mechanical parameters and millicandela rating. The forward voltage of 2V and test current of 10mA differ from the main part but remain within acceptable substitution parameters for red diffused rectangular through-hole LEDs.

MV57123 (onsemi): This part carries an obsolete product status designation. While it matches mechanical specifications and test current of 20mA, its obsolete status may present long-term supply chain risks. RoHS compliance status is not specified in the provided data.

XSUR18D (SunLED): This part maintains active product status and ROHS3 compliance. It matches all mechanical parameters with a slightly lower maximum height of 7.00mm. The forward voltage of 1.9V and test current of 10mA differ from the main part but remain within acceptable substitution parameters.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the Dialight 5219499F?

A: Substitution is based on matching the following parameters: red color, diffused lens transparency, 5.00mm x 2.00mm lens size, rectangle with flat top lens style, through-hole mounting, radial package, and millicandela rating of 3.7mcd or equivalent. Test current range of 10mA to 20mA and maximum height range of 7.00mm to 7.80mm are acceptable.

Q: Are there differences in forward voltage between the main part and substitutes?

A: Yes. The main part does not specify forward voltage. Substitute parts range from 1.9V to 2V. These variations are typical within the red diffused rectangular LED category and do not prevent substitution when circuit design accommodates the specified voltage range.

Q: Does product status affect substitution eligibility?

A: Product status is a supply chain consideration. The LTL-433HR and XSUR18D maintain active status, ensuring ongoing availability. The MV57123 is marked obsolete, which may limit future procurement options despite meeting electrical and mechanical criteria.

Q: Are all substitute parts RoHS3 compliant?

A: The LTL-433HR and XSUR18D are confirmed ROHS3 compliant. The MV57123 does not specify RoHS compliance status in the provided data.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes, all substitute parts share identical mechanical dimensions (5.00mm x 2.00mm lens size, rectangle with flat top style, through-hole radial package). PCB footprints and mounting holes are compatible. Circuit design must accommodate the specified forward voltage and test current of each substitute part.
