XLamp® ML-E MLEAWT-H1-0000-0003E5 Equivalent & Substitute Parts

Part Overview

The MLEAWT-H1-0000-0003E5 is a CreeLED XLamp® ML-E series white neutral LED designed for surface mount applications. This 4000K neutral white LED delivers 49 lumens at 25°C with a forward voltage of 3.2V and 150mA test current, achieving 102 lumens per watt efficiency. The component features a 120° viewing angle and is housed in a 4-SMD J-Lead Exposed Pad package measuring 4.60mm × 3.15mm. Currently in active production status with 860 units in stock, this LED is suitable for general illumination, display backlighting, and accent lighting applications where neutral white color temperature is required. Equivalent substitute parts are identified to provide design flexibility and supply chain alternatives while maintaining identical electrical and mechanical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MLEAWT-H1-0000-0003E5 are identified based on strict parametric equivalence within the XLamp® ML-E product family. The substitution criteria are defined by the following key parameters that must remain identical:

• Color and CCT: White, Neutral 4000K (3750K ~ 4250K tolerance band)
• Electrical Performance: Forward voltage 3.2V, test current 150mA, maximum current 175mA
• Optical Output: Flux 49lm @ 25°C (46 ~ 52lm range), flux 44lm @ 85°C, 102 lm/W efficiency
• Color Quality: CRI 80
• Mechanical Compatibility: 4-SMD J-Lead Exposed Pad package, 4.60mm × 3.15mm footprint, 1.33mm seated height
• Thermal Characteristics: 11°C/W thermal resistance
• Compliance: RoHS Compliant, MSL 2A (4 Weeks)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. Variations in part numbering within the base product number MLEAWT indicate different manufacturing batches, tape configurations, or internal revisions that do not affect functional or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the MLEAWT-H1-0000-0003E5 and MLEAWT-A1-R250-0003E5 are active production components from CreeLED with identical electrical, optical, and mechanical specifications. Selection between these parts may be based on:

• Inventory availability: MLEAWT-H1-0000-0003E5 has 860 units in stock; MLEAWT-A1-R250-0003E5 has 1343 units in stock
• Packaging configuration: Differences in tape reel specifications (indicated by the A1-R250 designation) may affect automated assembly line compatibility
• Supply chain lead times and procurement terms

Both parts carry identical RoHS Compliance and REACH Unaffected status, meeting regulatory requirements for EU and global markets. MSL 2A (4 Weeks) handling requirements apply to both components. No functional or performance trade-offs exist between these alternatives.

Frequently Asked Questions (FAQ)

Q: Can MLEAWT-A1-R250-0003E5 be used as a direct replacement for MLEAWT-H1-0000-0003E5?

A: Yes. Both parts are parametric equivalents with identical electrical performance (3.2V, 150mA), optical output (49lm @ 25°C, 102 lm/W), color characteristics (4000K neutral white, CRI 80), and mechanical specifications (4-SMD J-Lead Exposed Pad, 4.60mm × 3.15mm). They are interchangeable at the component level.

Q: What do the different part number suffixes indicate?

A: The base product number MLEAWT identifies the XLamp® ML-E white neutral LED family. Suffixes such as H1-0000 and A1-R250 indicate manufacturing batch codes, tape reel configurations, or internal revision levels. These variations do not affect functional performance or compatibility.

Q: Are there any PCB layout or thermal management differences between these parts?

A: No. Both parts have identical package dimensions (4.60mm × 3.15mm), seated height (1.33mm maximum), thermal resistance (11°C/W), and J-Lead Exposed Pad configuration. PCB footprints and thermal design requirements are identical.

Q: What is the MSL rating and how does it affect handling?

A: Both parts carry MSL 2A (4 Weeks), indicating they can be exposed to ambient conditions of 30°C / 60% RH for up to 4 weeks before reflow soldering. After this period, components must be baked according to IPC-A-2.1 standards before assembly.

Q: Are both parts RoHS compliant?

A: Yes. Both MLEAWT-H1-0000-0003E5 and MLEAWT-A1-R250-0003E5 are RoHS Compliant and REACH Unaffected, meeting EU regulatory requirements for hazardous substance restrictions.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection may be based on current inventory levels, supplier availability, or specific tape reel requirements for automated assembly equipment. No technical preference exists between them.
