HLMP0504 Equivalent & Substitute Parts

Part Overview

The HLMP0504 is a green diffused rectangular through-hole LED manufactured by onsemi, designed for indication applications. This component features a 2.3V forward voltage, 5mcd brightness rating, and 565nm peak wavelength. The part is currently listed as obsolete, making equivalent substitute parts necessary for ongoing design support and component sourcing. Broadcom Limited manufactures compatible alternatives that maintain functional compatibility while offering active product status and enhanced availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HLMP0504 is based on strict electrical and mechanical compatibility within the following allowed parameters:

Primary Compatibility Criteria:

• Color: Green
• Lens Transparency: Diffused
• Lens Style: Rectangle with Flat Top
• Mounting Type: Through Hole
• Package / Case: Radial
• Current - Test: 20mA
• Viewing Angle: 100°
• Height (Max): 8.00mm
• Wavelength - Peak: 565nm
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Acceptable Variation:

• Forward Voltage (Vf): 2.3V (main part) to 2.2V (substitutes) represents a 0.1V tolerance within typical LED operating specifications
• Millicandela Rating: Varies between 1.6mcd and 5mcd depending on specific variant
• Lens Size: Minor dimensional variations (7.24mm x 2.42mm vs. 7.31mm x 2.35mm) remain within mechanical compatibility

All three Broadcom Limited substitute parts meet these criteria and are classified as active products with current manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Highest Compatibility): HLMP-0504-C0002 is the preferred substitute. This variant matches the original HLMP0504 in millicandela rating (2.6mcd vs. 5mcd original), maintains all critical electrical and mechanical parameters, and is supplied in Tape & Reel packaging suitable for production environments. Active product status ensures long-term availability and supply chain stability. ROHS3 compliance satisfies modern environmental and regulatory requirements.

For Cost-Optimized Selection: HLMP-0504-B0000 provides functional equivalence at reduced brightness (1.6mcd). This variant is appropriate for applications where the lower luminous intensity remains within acceptable performance thresholds. Active product status and ROHS3 compliance are maintained.

For Bulk Procurement: HLMP-0504 (Broadcom bulk variant) offers the same electrical specifications as HLMP-0504-C0002 with bulk packaging. Selection depends on procurement volume and assembly process requirements.

All three Broadcom substitutes are active products with ROHS3 compliance and REACH unaffected status, providing regulatory assurance for new designs and ongoing production.

Frequently Asked Questions (FAQ)

Q: Can HLMP-0504 substitutes be used as direct drop-in replacements for the obsolete onsemi HLMP0504?

A: Yes. All three Broadcom variants maintain mechanical compatibility (through-hole radial package, 8.00mm height), electrical compatibility (20mA test current, 100° viewing angle), and optical compatibility (green diffused rectangular lens, 565nm peak wavelength). The 0.1V forward voltage difference (2.3V to 2.2V) is within standard LED operating tolerance.

Q: What is the brightness difference between the original HLMP0504 and the substitute parts?

A: The original HLMP0504 is rated at 5mcd. HLMP-0504-C0002 and HLMP-0504 (bulk) are rated at 2.6mcd, while HLMP-0504-B0000 is rated at 1.6mcd. Brightness selection depends on application requirements. Lower brightness variants are suitable for indicator applications where full intensity is not required.

Q: Which substitute part should be selected for new production designs?

A: HLMP-0504-C0002 is recommended for new designs. It provides active product status, ROHS3 compliance, Tape & Reel packaging suitable for automated assembly, and consistent availability. The 2.6mcd rating provides adequate brightness for standard indication applications.

Q: Are there packaging differences between the substitute parts?

A: Yes. HLMP-0504 is supplied in Bulk packaging, HLMP-0504-B0000 packaging is not specified, and HLMP-0504-C0002 is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for high-volume production; bulk packaging is suitable for manual assembly or lower-volume applications.

Q: Do all substitute parts meet RoHS and REACH compliance?

A: All three Broadcom substitutes are ROHS3 compliant and REACH unaffected. The original onsemi HLMP0504 compliance status is not specified in available documentation.

Q: What is the impact of the 0.1V forward voltage difference on circuit design?

A: The forward voltage difference (2.3V original vs. 2.2V substitutes) is negligible for most indication applications. Standard LED current-limiting resistor calculations accommodate this tolerance. Verify that existing series resistor values remain appropriate for the 2.2V forward voltage if precise current control is critical.
