HLMPD600 Equivalent & Substitute Parts

Part Overview

The HLMPD600 is a green LED indicator in T-1 3/4 through-hole package manufactured by onsemi. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The HLMPD600 operates at 2.1V forward voltage with 10mA test current and delivers 3mcd brightness with a 60° viewing angle. Substitute parts must maintain compatibility with the same mounting type, package form factor, and electrical operating parameters while accounting for variations in brightness, voltage rating, and lens characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the HLMPD600 is determined by the following criteria:

Primary Compatibility Parameters:

• Lens size: 5mm, T-1 3/4 form factor
• Mounting type: Through hole radial configuration
• Color: Green spectrum
• Viewing angle: 60° (preferred) or compatible alternative
• Forward voltage: 2.1V nominal (allows ±0.15V tolerance for active parts)
• Test current: 10mA nominal (allows ±2mA tolerance)

Secondary Compatibility Parameters:

• Lens transparency: Clear or diffused acceptable
• Millicandela rating: 3mcd minimum (higher brightness acceptable with circuit design consideration)
• Wavelength peak: 555nm to 569nm range
• Height: 8.60mm to 10.08mm acceptable
• RoHS/REACH compliance: Preferred for active parts

Voltage-Specific Substitutes: Parts rated at 5V or 12V forward voltage (4302H5-5V, 4302H5-12V) are not direct pin-compatible substitutes due to different voltage requirements and require circuit redesign with appropriate current-limiting resistors.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (2.1V Forward Voltage, Same Mounting):

HLMP-3507 and HLMP-3507-D00B1 are the primary direct substitutes for HLMPD600. Both are manufactured by Broadcom Limited and maintain the same 2.1V forward voltage and 10mA test current. These parts are active products with ROHS3 compliance. HLMP-3507 features a diffused lens with 4.2mcd brightness and 565nm peak wavelength. HLMP-3507-D00B1 is a right-angle variant suitable for applications requiring perpendicular PCB mounting. The slightly higher brightness (4.2mcd vs. 3mcd) and wavelength shift (565nm vs. 555nm) are within acceptable green LED specification ranges for indicator applications.

Compatible Substitutes (2.25V Forward Voltage, Same Mounting):

WP7113PGT manufactured by Kingbright operates at 2.25V forward voltage with 20mA test current. This part is pin-compatible with HLMPD600 in radial through-hole applications but requires circuit verification due to the 0.15V voltage increase and 2x current rating. The 30mcd brightness is significantly higher than HLMPD600, necessitating resistor adjustment in current-limiting circuits. The 20° viewing angle is narrower than HLMPD600's 60°, making it suitable only for applications where focused illumination is acceptable.

Voltage-Specific Alternatives (5V and 12V Forward Voltage):

4302H5-5V and 4302H5-12V are not direct pin-compatible substitutes due to their higher forward voltage ratings. These parts require complete circuit redesign with new current-limiting resistor values. Both are manufactured by Visual Communications Company - VCC and are active products with ROHS3 compliance. Selection of these parts is appropriate only when the application circuit is designed for 5V or 12V LED operation.

Frequently Asked Questions (FAQ)

Q: Can HLMP-3507 directly replace HLMPD600 without circuit modification?

A: Yes. HLMP-3507 maintains the same 2.1V forward voltage and 10mA test current as HLMPD600. Both are radial through-hole packages with 60° viewing angle. The 4.2mcd brightness is slightly higher than HLMPD600's 3mcd, but this increase is within acceptable tolerance for indicator applications. No circuit modification is required.

Q: What is the difference between HLMP-3507 and HLMP-3507-D00B1?

A: HLMP-3507 is a standard radial through-hole package. HLMP-3507-D00B1 is a right-angle variant designed for perpendicular mounting to the PCB. Both share identical electrical specifications (2.1V, 10mA, 4.2mcd). Selection depends on PCB layout requirements and mounting orientation.

Q: Can WP7113PGT replace HLMPD600?

A: WP7113PGT is mechanically compatible but requires circuit verification. The 2.25V forward voltage and 20mA test current differ from HLMPD600's 2.1V and 10mA specifications. The current-limiting resistor must be recalculated. The 30mcd brightness is 10x higher than HLMPD600, which may require resistor adjustment to achieve equivalent visual intensity. The 20° viewing angle is narrower than HLMPD600's 60°.

Q: Are 4302H5-5V and 4302H5-12V suitable substitutes?

A: 4302H5-5V and 4302H5-12V are not direct substitutes. These parts operate at 5V and 12V forward voltage respectively, requiring complete circuit redesign with new current-limiting resistors. Use these parts only when the application circuit is specifically designed for 5V or 12V LED operation.

Q: What compliance certifications should I verify for substitute parts?

A: All active substitute parts listed (HLMP-3507, HLMP-3507-D00B1, WP7113PGT, 4302H5-5V, 4302H5-12V) are ROHS3 compliant and REACH unaffected. All parts carry MSL 1 (Unlimited) moisture sensitivity rating. Verify specific compliance requirements for your application before final selection.

Q: How do wavelength differences affect substitution?

A: HLMPD600 has a 555nm peak wavelength. Substitute parts range from 557nm to 569nm. These differences represent normal variation within the green LED spectrum and are acceptable for indicator applications. Visual color perception differences are minimal across this range.

Q: What inventory status should I consider?

A: HLMPD600 is obsolete with 957 pieces in stock. Active substitutes have higher inventory availability: HLMP-3507 (4255 pcs), HLMP-3507-D00B1 (1225 pcs), WP7113PGT (980 pcs), 4302H5-5V (2739 pcs), and 4302H5-12V (1847 pcs). For long-term production, active parts are recommended.
