Key Parameters

Substitute Part Grouping Explanation

Substitution of the HLMP0503 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Color: Green
• Lens Transparency: Diffused
• Lens Style: Rectangle with Flat Top
• Mounting Type: Through Hole
• Package / Case: Radial
• Viewing Angle: 100°
• Height (Max): 8.00mm
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Voltage - Forward (Vf) Typical: ±0.1V tolerance
• Millicandela Rating: Within 10% of specified value
• Lens Size: ±0.1mm tolerance on dimensions
• Wavelength - Peak: ±5nm tolerance

The HLMP-0504 manufactured by Broadcom Limited meets all critical matching parameters and operates within allowable variation ranges for electrical characteristics, qualifying it as a direct substitute for the obsolete HLMP0503.

Parameter Comparison

Engineering Selection Recommendations

The HLMP-0504 manufactured by Broadcom Limited is the qualified substitute for the obsolete HLMP0503. Selection of this alternative is supported by the following factors:

Product Status: The HLMP-0504 maintains Active product status, ensuring continued availability and manufacturing support, whereas the HLMP0503 is classified as Obsolete.

Compliance Certifications: Both components share identical REACH Status (REACH Unaffected) and ECCN classification (EAR99), maintaining regulatory equivalence. The HLMP-0504 additionally carries RoHS3 Compliance certification, providing enhanced environmental compliance for new designs.

Electrical Compatibility: Forward voltage differential of 0.1V (2.3V vs 2.2V) falls within standard circuit design tolerances for LED indication applications. Millicandela rating variance of 0.4mcd (3mcd vs 2.6mcd) represents approximately 13% reduction in luminous intensity, acceptable for indication-class applications where absolute brightness is not critical.

Mechanical Compatibility: Lens dimensions and height specifications remain within manufacturing tolerance ranges. Radial package configuration and through-hole mounting type are identical, ensuring direct PCB footprint compatibility without layout modification.

Inventory Availability: The HLMP-0504 is available in higher stock quantity (1215 Pcs) compared to the HLMP0503 (988 Pcs), supporting procurement reliability.

Frequently Asked Questions (FAQ)

Q: Can the HLMP-0504 be used as a direct replacement for the HLMP0503 without circuit modification?

A: Yes. The HLMP-0504 operates at 2.2V forward voltage compared to the HLMP0503 at 2.3V. This 0.1V difference is within standard LED circuit design tolerances and does not require current-limiting resistor recalculation for typical 20mA test current applications. Through-hole radial package configuration and mechanical dimensions are identical.

Q: What is the significance of the millicandela rating difference between these parts?

A: The HLMP0503 delivers 3mcd while the HLMP-0504 delivers 2.6mcd at 20mA test current. This represents a 13% reduction in luminous intensity. For indication-class applications where the LED serves as a status indicator rather than a light source, this variance is functionally acceptable. Applications requiring specific brightness levels should evaluate this parameter against design requirements.

Q: Are there any compliance or regulatory differences between these components?

A: Both components share identical REACH Status (REACH Unaffected) and ECCN classification (EAR99). The HLMP-0504 carries additional RoHS3 Compliance certification. No regulatory barriers exist to substitution.

Q: How do the lens dimensions compare between these parts?

A: The HLMP0503 lens measures 7.24mm x 2.42mm while the HLMP-0504 lens measures 7.31mm x 2.35mm. Dimensional variance is 0.07mm and 0.07mm respectively, representing less than 1% tolerance variation. Both maintain identical rectangular flat-top lens style and diffused transparency. PCB footprint compatibility is maintained.

Q: What is the wavelength specification for each component?

A: Both components specify 565nm peak wavelength, confirming identical green LED spectral characteristics. The HLMP-0504 additionally specifies 569nm dominant wavelength, providing additional spectral definition. This does not affect substitution compatibility.

Q: Why is the HLMP0503 classified as Obsolete?

A: Product status reflects manufacturer discontinuation decisions. The HLMP-0504 maintains Active status, ensuring continued manufacturing support and component availability for new designs and ongoing production requirements.
