Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5219498 is determined by the following critical parameters:

Primary Substitution Criteria:

• Lens color: Orange
• Lens transparency: Diffused
• Mounting type: Through Hole
• Lens size: 3mm
• Viewing angle: 60°
• Package type: Radial

Secondary Compatibility Parameters:

• Forward voltage (Vf): 1.9V to 2.2V range
• Test current: 10mA to 20mA range
• Wavelength - Peak: 600nm to 602nm range
• Millicandela rating: 2.1mcd minimum

The 5219498F is a direct equivalent with identical specifications and improved product status. The HLMP-K401 series (HLMP-K401, HLMP-K401-E0002) provides functional substitution with orange diffused lenses and compatible electrical parameters, though with lower millicandela ratings and slightly reduced forward voltage.

The HLMP-1401 series (HLMP-1401, HLMP-1401-D0002, HLMP-1401-E0000) are yellow-emitting alternatives that share mechanical compatibility and electrical operating ranges but differ in color and wavelength characteristics.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Recommended): The 5219498F is the primary substitute for the obsolete 5219498. Both parts share identical electrical and optical specifications with matching forward voltage (2.2V), test current (20mA), and millicandela rating (7mcd). The 5219498F carries active product status and ROHS3 compliance, addressing regulatory requirements for new designs and production continuity.

Orange-Emitting Alternatives: The HLMP-K401 and HLMP-K401-E0002 (Broadcom Limited) provide orange-emitting substitutes with compatible 600nm peak wavelength. These parts operate at reduced forward voltage (1.9V) and test current (10mA), resulting in lower millicandela ratings (2.1mcd to 3.4mcd). Both variants maintain active product status and ROHS3 compliance. Height specification increases to 6.35mm. Selection between HLMP-K401 (Bulk) and HLMP-K401-E0002 (Tape & Reel) depends on packaging requirements.

Yellow-Emitting Alternatives: The HLMP-1401 series (HLMP-1401, HLMP-1401-D0002, HLMP-1401-E0000) offers mechanical and electrical compatibility with yellow emission at 583nm to 585nm wavelength. Forward voltage is 2V with 10mA test current. Millicandela ratings range from 2.2mcd to 5.7mcd. These parts are suitable only when yellow indication is functionally acceptable in the application. Packaging options include Bulk, Cut Tape, and Tape & Reel formats.

All substitute parts maintain MSL 1 (Unlimited) moisture sensitivity and 60° viewing angle specifications consistent with the original 5219498.

Frequently Asked Questions (FAQ)

Q: Can the 5219498F directly replace the obsolete 5219498? A: Yes. The 5219498F is the active production equivalent with identical electrical and optical specifications. The only differences are product status (Active vs. Obsolete) and RoHS compliance (ROHS3 vs. non-compliant). No circuit modifications are required.

Q: What are the key differences between the Dialight 5219498F and Broadcom HLMP-K401? A: Both are orange-emitting 3mm diffused LEDs with 600nm peak wavelength and 60° viewing angle. The 5219498F operates at 2.2V/20mA with 7mcd brightness, while the HLMP-K401 operates at 1.9V/10mA with 2.1mcd brightness. The 5219498F provides higher brightness and forward voltage. Height increases from 6.00mm to 6.35mm for the HLMP-K401.

Q: Can I use HLMP-1401 (yellow) instead of the orange 5219498? A: Mechanical and electrical compatibility exists, but color output differs. HLMP-1401 emits yellow at 583nm to 585nm versus the 5219498's orange at 600nm. Use only if the application accepts yellow indication or if color filtering is applied.

Q: What packaging options are available for substitutes? A: The 5219498F is available in Bulk packaging. The HLMP-K401 series offers Bulk and Tape & Reel (TR) options. The HLMP-1401 series provides Bulk, Cut Tape (CT), and Tape & Reel formats. Select based on assembly process requirements and order quantities.

Q: Are all substitute parts RoHS3 compliant? A: Yes. The 5219498F and all Broadcom HLMP series parts carry ROHS3 Compliant status. The original 5219498 is RoHS non-compliant. Compliance is required for new designs and many production environments.

Q: What is the brightness difference between 5219498 and HLMP-K401? A: The 5219498 provides 7mcd at 20mA test current. The HLMP-K401 provides 2.1mcd at 10mA test current. Direct brightness comparison requires accounting for different test currents. At equivalent operating conditions, the 5219498 delivers higher luminous intensity.

Q: Can I use HLMP-K401-E0002 in tape and reel format for high-volume assembly? A: Yes. The HLMP-K401-E0002 is supplied in Tape & Reel (TR) format, suitable for automated pick-and-place assembly. Specifications are identical to HLMP-K401 except for higher millicandela rating (3.4mcd vs. 2.1mcd) and packaging format.
