Key Parameters

Substitute Part Grouping Explanation

The LXML-PR01-0500 qualifies as a direct substitute based on the following matching parameters:

• Identical wavelength specification: 448nm (Typ)
• Identical forward voltage: 2.95V
• Identical test current: 350mA
• Identical maximum current: 1A
• Identical viewing angle: 125°
• Identical thermal resistance: 10°C/W
• Identical mounting type: Surface Mount
• Identical RoHS3 compliance status
• Identical MSL rating: 1 (Unlimited)
• Compatible package dimensions: 0.177" L x 0.120" W (4.49mm x 3.05mm)
• Identical height specification: 0.083" (2.10mm)

The primary distinction is product status: LXML-PR01-0425 is obsolete while LXML-PR01-0500 is active, with improved supply availability (5071 pcs in stock versus 1428 pcs).

Parameter Comparison

Engineering Selection Recommendations

The LXML-PR01-0500 is the appropriate substitute for LXML-PR01-0425 applications. Both components maintain identical electrical performance characteristics and mechanical compatibility. The substitute part carries active product status with established supply chain availability, eliminating obsolescence risk. Both parts satisfy ROHS3 compliance requirements and maintain equivalent thermal management specifications. The LXML-PR01-0500 provides additional luminous flux data (520mW at 25°C), supporting more precise optical design calculations.

Frequently Asked Questions (FAQ)

Q: Can LXML-PR01-0500 replace LXML-PR01-0425 in existing designs?

A: Yes. Both parts share identical electrical parameters (2.95V forward voltage, 350mA test current, 1A maximum current), identical wavelength (448nm), and identical mechanical dimensions (0.177" L x 0.120" W, 0.083" height). Surface mount compatibility and thermal resistance (10°C/W) are equivalent.

Q: What is the difference between package designations 1816 (4540 Metric) and 1812 (4532 Metric)?

A: Both designations refer to surface mount packages with identical external dimensions (0.177" L x 0.120" W, 0.083" height). The numeric differences reflect internal package architecture that does not affect PCB footprint or electrical performance.

Q: Are there compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, carry MSL rating 1 (Unlimited), and share identical REACH and ECCN classifications.

Q: Why is LXML-PR01-0425 classified as obsolete?

A: Product obsolescence reflects manufacturer discontinuation. LXML-PR01-0500 remains in active production with superior inventory availability (5071 pcs versus 1428 pcs).

Q: Is luminous flux specification critical for substitution?

A: The LXML-PR01-0500 provides luminous flux data (520mW at 25°C) not specified for LXML-PR01-0425. This additional specification supports optical design verification but does not affect electrical or mechanical substitution compatibility.
