Substitute Part Grouping Explanation

The MLEAWT-A1-R250-0001E7 is classified as a parametric equivalent to the MLEAWT-U1-0000-0001E7. Substitution eligibility is determined by the following critical parameters:

• Color and CCT specification: Both parts are White, Warm 3000K (2850K ~ 3250K)
• Forward voltage: Both rated at 3.2V typical
• Test current: Both specified at 150mA
• Luminous flux @ 25°C: Both deliver 38lm (35lm ~ 40lm)
• Lumens/Watt efficiency: Both achieve 79 lm/W
• Viewing angle: Both provide 120° beam angle
• Package footprint: Both use 4-SMD, J-Lead Exposed Pad with identical dimensions (4.60mm x 3.15mm)
• Height: Both measure 0.052" (1.33mm) maximum seated height
• Thermal resistance: Both rated at 11°C/W

The primary difference between these parts is the packaging format: MLEAWT-U1-0000-0001E7 is supplied in Tape & Reel (TR), while MLEAWT-A1-R250-0001E7 is supplied in Cut Tape (CT). Both parts share the same base product number (MLEAWT) and are from the same XLamp® ML-E series.

Parameter Comparison

Engineering Selection Recommendations

Both MLEAWT-U1-0000-0001E7 and MLEAWT-A1-R250-0001E7 are active products from CreeLED with full RoHS compliance and identical MSL ratings. Selection between these parts is determined by packaging requirements and operational constraints.

The MLEAWT-U1-0000-0001E7 (Tape & Reel) is suitable for high-volume automated assembly operations where continuous reel feeding is required. The MLEAWT-A1-R250-0001E7 (Cut Tape) is appropriate for lower-volume applications, manual assembly, or situations where partial reel quantities are needed.

The MLEAWT-A1-R250-0001E7 has a lower maximum current rating (175mA vs. 500mA) and a lower CRI specification (80 vs. 90). These differences must be evaluated against application requirements. If the application requires the full 500mA maximum current capability or the higher CRI value of 90, the MLEAWT-U1-0000-0001E7 is the appropriate selection. For applications operating at or below 150mA test current with CRI 80 acceptable, the MLEAWT-A1-R250-0001E7 provides equivalent optical and thermal performance.

Frequently Asked Questions (FAQ)

Q: Can MLEAWT-A1-R250-0001E7 be used as a direct replacement for MLEAWT-U1-0000-0001E7 on the PCB?

A: Yes, from a mechanical and electrical standpoint. Both parts have identical footprints (4.60mm x 3.15mm), identical package type (4-SMD, J-Lead Exposed Pad), and identical height (1.33mm maximum). The solder pad layout and reflow profile requirements are identical. However, the lower maximum current rating (175mA vs. 500mA) and lower CRI (80 vs. 90) must be evaluated for your specific application.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging supplies components on a continuous reel suitable for automated pick-and-place equipment in high-volume manufacturing. Cut Tape packaging provides components on a tape strip cut to a specific length, typically used for lower-volume orders, manual assembly, or when partial quantities are required. The component itself is identical; only the delivery format differs.

Q: Are there any thermal or optical performance differences between these parts?

A: Thermal resistance is identical at 11°C/W. Luminous flux at 25°C test current (38lm) and lumens/watt efficiency (79 lm/W) are identical. The CRI differs: MLEAWT-U1-0000-0001E7 has CRI 90, while MLEAWT-A1-R250-0001E7 has CRI 80. This affects color rendering quality in applications where high color accuracy is critical.

Q: What does the maximum current difference mean for my application?

A: The MLEAWT-U1-0000-0001E7 can operate up to 500mA maximum, while MLEAWT-A1-R250-0001E7 is limited to 175mA maximum. Both are tested and specified at 150mA. If your circuit design requires operation above 175mA, only the MLEAWT-U1-0000-0001E7 is suitable. For applications operating at or below 150mA, both parts are functionally equivalent.

Q: Are both parts RoHS compliant?

A: Yes, both MLEAWT-U1-0000-0001E7 and MLEAWT-A1-R250-0001E7 are RoHS compliant with identical MSL 2A (4 Weeks) moisture sensitivity ratings.
