• Lens Size: 3mm diameter
• Lens Transparency: Diffused
• Color: Orange (primary) or functionally equivalent wavelength (600nm peak)
• Voltage - Forward (Vf): 1.9V to 2.2V range
• Viewing Angle: 60°
• Package / Case: Radial

Secondary Compatibility Criteria:

• Current - Test: 10mA to 20mA operating range
• Millicandela Rating: 2.1mcd to 7mcd (brightness variation acceptable for indication applications)
• Height (Max): 6.00mm to 6.35mm (PCB clearance tolerance)
• RoHS Status: ROHS3 Compliant
• Product Status: Active

The substitute parts listed below meet these criteria and are functionally interchangeable in LED indication circuits where the Dialight 5219498F is specified.

Parameter Comparison

Engineering Selection Recommendations

Broadcom HLMP-K401 (Primary Substitute)

The HLMP-K401 is the closest functional equivalent to the Dialight 5219498F. Both components feature orange color, 600nm peak wavelength, 3mm diffused lens, 60° viewing angle, and through-hole radial mounting. The HLMP-K401 operates at 1.9V forward voltage (0.3V lower than the 5219498F) and 10mA test current (10mA lower than the 5219498F). The 2.1mcd brightness rating is lower than the 5219498F's 7mcd, but remains suitable for indication applications. Both components are ROHS3 compliant and Active status. Height difference of 0.35mm (6.35mm vs 6.00mm) is within acceptable PCB clearance tolerances for standard through-hole designs.

Broadcom HLMP-1401-E0000 (Secondary Substitute - Color Variation)

The HLMP-1401-E0000 provides the highest brightness among yellow alternatives at 5.7mcd, closest to the 5219498F's 7mcd rating. This component shares identical mechanical and optical specifications (3mm diffused lens, 60° viewing angle, through-hole radial mounting) but operates at 2V forward voltage and 10mA test current. The yellow color (585nm dominant wavelength) differs from the orange specification but maintains the same lens transparency and viewing characteristics. ROHS3 compliance and Active status are confirmed. This substitute is suitable for applications where color indication can be modified or where yellow and orange are functionally interchangeable.

Broadcom HLMP-1401-D0002 (Secondary Substitute - Packaging Variant)

The HLMP-1401-D0002 is identical to HLMP-1401-E0000 in electrical and optical specifications (2V forward voltage, 10mA test current, 3.6mcd brightness, 585nm wavelength) but supplied in Cut Tape (CT) packaging instead of Bulk. This variant is suitable for automated assembly processes requiring tape-and-reel format. All compliance and compatibility parameters remain equivalent.

Broadcom HLMP-1401 (Tertiary Substitute - Lowest Brightness)

The HLMP-1401 offers the lowest brightness option at 2.2mcd but maintains all other compatibility parameters (2V forward voltage, 10mA test current, 3mm diffused lens, 60° viewing angle, through-hole radial mounting, yellow color). This variant is suitable only for applications where reduced brightness is acceptable or preferred.

All substitute parts are Active status and ROHS3 compliant, confirming suitability for current production and regulatory compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the Broadcom HLMP-K401 directly replace the Dialight 5219498F without circuit modification?

A: The HLMP-K401 is mechanically and optically compatible (same lens size, transparency, viewing angle, and mounting type). However, the forward voltage difference (1.9V vs 2.2V) and test current difference (10mA vs 20mA) may require circuit resistor recalculation to maintain proper brightness and current limiting. Verify the LED circuit design accommodates the lower voltage and current specifications before substitution.

Q: Why are the Broadcom HLMP-1401 variants listed as substitutes if they are yellow instead of orange?

A: The HLMP-1401 series shares identical mechanical specifications (3mm diffused lens, through-hole radial mounting, 60° viewing angle, 6.35mm height) and electrical operating ranges (2V forward voltage, 10mA test current) with the Dialight 5219498F. These components are functionally interchangeable in indication circuits where color variation is acceptable or where yellow and orange indication serve equivalent purposes. The diffused lens transparency and viewing angle ensure consistent visual performance.

Q: What is the significance of the 0.35mm height difference between the Dialight 5219498F (6.00mm) and Broadcom substitutes (6.35mm)?

A: The height difference is within standard PCB clearance tolerances for through-hole components. Most PCB designs accommodate ±0.5mm height variation for radial-mounted LEDs. Verify clearance in your specific PCB layout, particularly if components are mounted near low-profile shields or enclosures.

Q: Are all listed substitutes ROHS3 compliant and Active status?

A: Yes. All substitute parts (HLMP-1401, HLMP-1401-D0002, HLMP-1401-E0000, and HLMP-K401) are ROHS3 compliant and Active status, matching the Dialight 5219498F compliance profile. This ensures regulatory compliance and continued availability for production applications.

Q: What is the difference between HLMP-1401-E0000 and HLMP-1401-D0002?

A: Both components are electrically and optically identical (2V forward voltage, 10mA test current, 3.6mcd brightness, 585nm wavelength, 3mm diffused lens, 60° viewing angle). The primary difference is packaging: HLMP-1401-E0000 is supplied in Bulk packaging, while HLMP-1401-D0002 is supplied in Cut Tape (CT) format. Select based on assembly process requirements (manual assembly typically uses Bulk; automated assembly typically uses tape-and-reel).

Q: Can the lower brightness Broadcom HLMP-1401 (2.2mcd) be used in place of the Dialight 5219498F (7mcd)?

A: The HLMP-1401 is mechanically and electrically compatible but provides significantly lower brightness (2.2mcd vs 7mcd). Substitution is suitable only if the application tolerates reduced brightness or if the circuit design does not depend on the higher luminous intensity. Verify brightness requirements in your specific indication application before substitution.
