HLMP0504 Equivalent & Substitute Parts

Part Overview

The HLMP0504 is a green diffused rectangular through-hole LED manufactured by Everlight Electronics Co Ltd, designed for indication applications. This component features a 2.3V forward voltage, 5mcd brightness rating, and a rectangular lens form factor with 100° viewing angle. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional compatibility for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HLMP0504 is determined by strict alignment with the following parameters: color (green), lens transparency (diffused), lens style (rectangle with flat top), mounting type (through hole), package type (radial), peak wavelength (565nm), maximum height (8.00mm), and moisture sensitivity level (1 - Unlimited). The forward voltage tolerance range of 2.0V to 2.3V and test current of 20mA establish the electrical operating envelope. Viewing angle variation between 100° and 110° is acceptable within the rectangular diffused LED category. Millicandela ratings may vary within the discrete indication LED range. All substitute parts must maintain active product status or equivalent compliance certifications to ensure long-term availability and manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The HLMP-0504 manufactured by Broadcom Limited is an active equivalent substitute with identical mechanical dimensions (8.00mm height), matching lens style (rectangle with flat top), and equivalent electrical characteristics within the specified operating envelope. The forward voltage of 2.2V operates within acceptable tolerance of the original 2.3V specification. This part maintains ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment for current production environments.

The SSL-LX25783GD manufactured by Lumex Opto/Components Inc. is an active substitute with compatible mechanical form factor and electrical test current. The forward voltage of 2V represents a lower operating point within the acceptable range for green diffused rectangular LEDs. This part offers higher millicandela output (9mcd versus 5mcd) and an expanded viewing angle (110° versus 100°), providing enhanced optical performance characteristics. ROHS3 compliance and REACH Unaffected status confirm regulatory compatibility.

Both substitute parts maintain through-hole radial mounting configuration, identical maximum height specification, and unlimited moisture sensitivity rating. Selection between HLMP-0504 (Broadcom) and SSL-LX25783GD (Lumex) depends on circuit voltage tolerance requirements and brightness performance needs for the specific indication application.

Frequently Asked Questions (FAQ)

Q: Can the HLMP-0504 be directly replaced with the HLMP-0504 from Broadcom?

A: Yes. Both parts share identical part number designation, matching mechanical dimensions (8.00mm height, 7.24mm x 2.42mm to 7.31mm x 2.35mm lens size), equivalent lens style (rectangle with flat top), and compatible electrical specifications (2.2V forward voltage versus 2.3V original). The Broadcom version maintains active product status and ROHS3 compliance.

Q: What are the electrical differences between substitute options?

A: The Broadcom HLMP-0504 operates at 2.2V forward voltage compared to the original 2.3V. The Lumex SSL-LX25783GD operates at 2V forward voltage. All three parts maintain 20mA test current specification. Forward voltage variation within this range is acceptable for indication LED applications operating from standard 5V or 3.3V logic supplies with appropriate current-limiting resistor selection.

Q: Are the lens dimensions interchangeable?

A: Lens dimensions vary slightly across substitutes. The original HLMP0504 specifies 7.24mm x 2.42mm, the Broadcom HLMP-0504 specifies 7.31mm x 2.35mm, and the Lumex SSL-LX25783GD specifies 7.00mm x 2.30mm. All three maintain rectangular form factor with flat top style and 8.00mm maximum height. PCB layout and mechanical clearance must accommodate the specific lens dimensions of the selected substitute.

Q: How do brightness ratings compare?

A: The original HLMP0504 provides 5mcd brightness. The Broadcom HLMP-0504 provides 2.6mcd, representing lower optical output. The Lumex SSL-LX25783GD provides 9mcd, representing higher optical output. Brightness selection depends on indication visibility requirements in the target application environment.

Q: What is the viewing angle difference?

A: The original HLMP0504 and Broadcom HLMP-0504 both specify 100° viewing angle. The Lumex SSL-LX25783GD specifies 110° viewing angle, providing a 10° wider light distribution pattern. This difference is acceptable within the diffused rectangular LED category and may improve visibility in applications requiring wider angular light distribution.

Q: Are all substitutes compliant with current regulations?

A: Both active substitutes (Broadcom HLMP-0504 and Lumex SSL-LX25783GD) maintain ROHS3 compliance and REACH Unaffected status. The original Everlight HLMP0504 is classified as obsolete but carries REACH Unaffected designation. All three parts carry EAR99 ECCN classification and 8541.41.0000 HTSUS code.

Q: Which substitute should be selected for new designs?

A: For new designs, either active substitute is acceptable based on application requirements. The Broadcom HLMP-0504 provides closest electrical match to the original specification (2.2V versus 2.3V). The Lumex SSL-LX25783GD provides enhanced brightness (9mcd) and wider viewing angle (110°) if these performance characteristics benefit the application. Both maintain identical mechanical mounting and regulatory compliance.
