LUXEON Z Amber LED LXZ1-PL01 Equivalent & Substitute Parts

Part Overview

The LXZ1-PL01 is a LUXEON Z series amber LED emitter manufactured by Lumileds, designed for surface mount applications in the 0705 (1713 Metric) package. This component operates at 590nm wavelength (585nm–595nm range) with a forward voltage of 2.15V at 500mA test current and delivers 56lm luminous flux at 25°C. The part is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing production and maintenance applications. The LXZ1-PL03 serves as the manufacturer-recommended substitute, offering comparable electrical and mechanical characteristics within the same LUXEON Z product family.

Substitute Part Grouping Explanation

Substitution eligibility for the LXZ1-PL01 is determined by the following critical parameters:

Wavelength compatibility: Amber color range (585–595nm) ensures consistent optical output for applications requiring this specific spectral region
Electrical ratings: Maximum current (700mA) and forward voltage characteristics must support existing circuit designs without modification
Package and mounting: 0705 (1713 Metric) surface mount package ensures mechanical and thermal compatibility with PCB layouts
Compliance certifications: RoHS3 and REACH status maintain regulatory alignment across manufacturing jurisdictions

The LXZ1-PL03 qualifies as a direct substitute based on shared base product number (LXZ1), identical package specification, matching maximum current rating, and equivalent compliance certifications. Both components are part of the LUXEON Z amber LED family and maintain the same 145° viewing angle and surface mount configuration.

Parameter Comparison

Parameter	LXZ1-PL01 (Main)	LXZ1-PL03 (Substitute)	Compatibility Notes
Wavelength	590 (585–595) nm	599 nm	Both within amber spectrum; LXZ1-PL03 at upper range
Forward Voltage (Vf) @ 500mA	2.15 V	2.25 V	0.10V differential; verify circuit headroom
Maximum Current	700 mA	700 mA	Identical rating
Lumens/Watt @ 500mA	52 lm/W	18 lm/W	Significant efficiency difference; LXZ1-PL01 superior
Viewing Angle	145°	145°	Identical
Package / Case	0705 (1713 Metric)	0705 (1713 Metric)	Identical; direct PCB compatibility
Height - Seated (Max)	0.66 mm	0.96 mm	0.30mm height increase; verify clearance
Thermal Resistance	8°C/W	Not specified	Thermal design verification recommended
RoHS Status	ROHS3 Compliant	ROHS3 Compliant	Identical compliance
MSL Rating	1 (Unlimited)	1 (Unlimited)	Identical moisture sensitivity
Product Status	Obsolete	Active	LXZ1-PL03 actively manufactured

Engineering Selection Recommendations

The LXZ1-PL03 is the manufacturer-designated substitute for the obsolete LXZ1-PL01. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity. The LXZ1-PL03 is currently in active production with confirmed inventory availability (3160 pcs), whereas the LXZ1-PL01 is obsolete with limited stock (644 pcs).

Key considerations for implementation:

Forward voltage differential: The 0.10V increase (2.15V to 2.25V) requires verification that existing power supply designs provide adequate headroom
Luminous efficiency: The LXZ1-PL01 delivers 52 lm/W compared to 18 lm/W for the LXZ1-PL03; applications sensitive to power consumption or thermal output must account for this difference
Physical height: The LXZ1-PL03 seated height increases from 0.66mm to 0.96mm; confirm PCB assembly clearance and reflow profile compatibility
Wavelength shift: The LXZ1-PL03 operates at 599nm versus 590nm for the LXZ1-PL01; verify color consistency requirements for visual applications

Frequently Asked Questions (FAQ)

Q: Can LXZ1-PL03 be used as a direct drop-in replacement for LXZ1-PL01?

A: Mechanical compatibility is confirmed (identical 0705 package, same footprint). Electrical verification is required due to forward voltage and efficiency differences. The 0.30mm height increase must be cleared with PCB assembly specifications.

Q: What is the impact of the wavelength difference (590nm vs. 599nm)?

A: Both wavelengths fall within the amber spectrum (585–595nm for LXZ1-PL01; 599nm for LXZ1-PL03). The LXZ1-PL03 operates at the upper boundary. Applications requiring precise color matching should conduct spectral validation.

Q: Why is the lumens/watt efficiency significantly lower for LXZ1-PL03?

A: The efficiency difference (52 lm/W vs. 18 lm/W) reflects different test conditions and product generations within the LUXEON Z family. The LXZ1-PL03 test temperature is 85°C versus 25°C for the LXZ1-PL01, contributing to the apparent efficiency variance.

Q: Are there any compliance or certification differences?

A: Both parts maintain identical RoHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) moisture sensitivity ratings. No compliance barriers exist for substitution.

Q: What packaging options are available for LXZ1-PL03?

A: The LXZ1-PL03 is supplied in Tape & Reel (TR) format, whereas the LXZ1-PL01 packaging specification is not detailed. Confirm reel specifications and handling requirements for your assembly process.
