Electrical Differences: The substitute part operates at different electrical parameters (forward voltage and test current), requiring circuit design verification to ensure compatibility with existing power supply and current-limiting configurations.

Parameter Comparison

Engineering Selection Recommendations

The MX3AWT-A1-0000-000AB1 is the designated substitute for the obsolete MX3SWT-A1-0000-000AB1. Both parts share identical mechanical, optical, and environmental specifications, ensuring PCB-level compatibility without layout or thermal redesign.

The substitute part carries Active product status, providing long-term availability and supply chain stability compared to the obsolete main part. The MX3AWT-A1-0000-000AB1 is RoHS Compliant, meeting current regulatory requirements for new designs and production batches.

Electrical parameter differences require circuit-level evaluation. The substitute operates at 3.7V forward voltage with 350mA test current, compared to the main part's 10.7V and 115mA. Power supply and current-limiting configurations must be adjusted accordingly to maintain proper LED operation and thermal management.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-000AB1 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000AB1?

A: The parts are mechanically and optically compatible at the PCB level due to identical package dimensions, footprint, and luminous output. However, the electrical parameters differ significantly. Circuit redesign is required to accommodate the different forward voltage (3.7V vs. 10.7V) and test current (350mA vs. 115mA) specifications.

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts maintain identical REACH and ECCN classifications. The substitute part is RoHS Compliant, whereas the main part's RoHS status is not specified. For new designs or production requiring RoHS compliance, the substitute part is the appropriate selection.

Q: What is the impact of the different lumens/watt ratings?

A: The main part delivers 74 lm/W at its test current, while the substitute delivers 70 lm/W at its test current. Both parts produce identical luminous flux (91lm) at their respective operating points, so optical output remains equivalent when properly driven at specified currents.

Q: Are the thermal characteristics identical?

A: Yes. Both parts have identical thermal resistance of 11°C/W and identical maximum seated height of 1.48mm, ensuring equivalent thermal performance in the same PCB layout and thermal environment.

Q: What packaging options are available for the substitute part?

A: The MX3AWT-A1-0000-000AB1 is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. The main part's packaging format is not specified in the available data.
