Engineering Selection Recommendations

Both parts are active products from CreeLED, Inc., with identical RoHS compliance and REACH unaffected status. Selection between MLEAWT-H1-0000-0001E7 and MLEAWT-A1-R250-0001E7 depends on packaging and current handling requirements:

MLEAWT-H1-0000-0001E7 is appropriate for high-volume automated assembly requiring Tape & Reel packaging and applications where maximum current capability of 500mA may be utilized.
MLEAWT-A1-R250-0001E7 is appropriate for lower-volume or manual assembly processes utilizing Cut Tape packaging, with operation limited to 175mA maximum current.

At the specified test current of 150mA, both parts deliver identical optical and thermal performance. Selection should be based on assembly process requirements and maximum current headroom needed for the application.

Frequently Asked Questions (FAQ)

Q: Can MLEAWT-A1-R250-0001E7 be used as a direct replacement for MLEAWT-H1-0000-0001E7?

A: Yes, for applications operating at or below 150mA. Both parts deliver identical flux, forward voltage, color temperature, and thermal characteristics at this current level. The primary difference is packaging format (Cut Tape vs. Tape & Reel) and maximum current rating (175mA vs. 500mA).

Q: What is the significance of the different maximum current ratings?

A: The MLEAWT-H1-0000-0001E7 supports up to 500mA maximum current, while MLEAWT-A1-R250-0001E7 supports 175mA maximum. If your application requires operation above 175mA, the MLEAWT-H1-0000-0001E7 must be used. At 150mA test current, both parts operate within their rated limits.

Q: Does packaging format affect electrical or optical performance?

A: No. Tape & Reel (TR) and Cut Tape (CT) packaging formats are supply chain and assembly process considerations only. They do not affect the electrical characteristics, optical output, or thermal performance of the LED itself.

Q: Are both parts RoHS compliant?

A: Yes. Both MLEAWT-H1-0000-0001E7 and MLEAWT-A1-R250-0001E7 are RoHS compliant and REACH unaffected.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: Both parts carry an MSL rating of 2A with a 4-week floor life. Standard moisture control procedures for SMD components apply.
