LXA7-PW30 Equivalent & Substitute Parts

Part Overview

The LXA7-PW30 is a LUXEON R series warm white LED (3000K) designed for surface mount applications in lighting systems. This component features a 1812 (4532 Metric) package with a forward voltage of 2.81V at 700mA test current and delivers 180lm typical output at 85°C. The product is currently obsolete, necessitating identification of active equivalent components that maintain functional compatibility for new designs or production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LXA7-PW30 is determined by the following critical parameters:

• Color and correlated color temperature (CCT): White, Warm 3000K 5-Step MacAdam Ellipse
• Forward voltage range: 2.81V nominal at 700mA test current
• Test current compatibility: 700mA
• Viewing angle: 120°
• Mounting type: Surface Mount
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

The substitute part L1T2-3090500001900 (LUXEON TX series) maintains functional equivalence through matching color specification, CCT tolerance, test current, viewing angle, and regulatory compliance. While package geometry differs (2-SMD vs. 1812), both components are surface mount devices with compatible thermal and electrical operating characteristics within the specified parameter ranges.

Parameter Comparison

Engineering Selection Recommendations

The L1T2-3090500001900 is the manufacturer-recommended substitute for the obsolete LXA7-PW30. Both components meet ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity. The substitute demonstrates improved performance characteristics: higher luminous flux (188lm vs. 180lm at 85°C), superior luminous efficacy (96 lm/W vs. 92 lm/W), enhanced color rendering index (90 vs. 70), and lower thermal resistance (3°C/W vs. 6°C/W). Forward voltage remains within 0.01V nominal difference (2.8V vs. 2.81V), maintaining circuit compatibility. Maximum current rating increases from 1A to 1.5A, providing additional operational margin. Package geometry change from 1812 to 2-SMD requires PCB layout modification but maintains equivalent mounting height (2.10mm vs. 2.12mm seated).

Frequently Asked Questions (FAQ)

Q: Can the L1T2-3090500001900 directly replace the LXA7-PW30 without circuit modification?

A: Forward voltage compatibility (2.8V vs. 2.81V at 700mA) permits direct electrical substitution in most driver circuits. However, package geometry differs (2-SMD vs. 1812), requiring PCB footprint redesign. Thermal performance improves with the substitute (3°C/W vs. 6°C/W), reducing thermal management requirements.

Q: Are the color specifications identical between the two parts?

A: Both components specify White, Warm 3000K with 5-Step MacAdam Ellipse tolerance. The substitute offers higher CRI (90 vs. 70), indicating superior color rendering capability within the same CCT specification.

Q: What are the key differences in maximum operating current?

A: The LXA7-PW30 is rated for 1A maximum current, while the L1T2-3090500001900 supports 1.5A maximum. Both are tested and specified at 700mA. The increased maximum rating on the substitute provides additional design margin for peak current conditions.

Q: Do both parts meet the same regulatory requirements?

A: Both components are ROHS3 compliant and REACH unaffected, ensuring equivalent regulatory status for applications requiring these certifications.

Q: What is the impact of package change on thermal management?

A: The substitute's 2-SMD package exhibits superior thermal resistance (3°C/W vs. 6°C/W), resulting in lower junction temperatures at equivalent power dissipation. This improvement reduces thermal design burden in the application circuit.
