Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX3SWT-A1-0000-000AB9 is determined by the following critical parameters:

Mechanical Compatibility: Package type (2-SMD, Gull Wing Exposed Pad), footprint dimensions (5.00mm × 5.00mm), and maximum seated height (1.48mm) must remain identical to ensure PCB assembly compatibility without design modification.

Optical Compatibility: Color (white) and viewing angle (120°) must match to preserve optical performance in the application.

Electrical Compatibility: Forward voltage, test current, maximum current, and luminous flux output must fall within acceptable ranges for the circuit design. The substitute part must operate within the power supply and current-limiting constraints of the original design.

Environmental & Compliance: Moisture sensitivity level (MSL 2A), REACH status, and thermal resistance characteristics must be equivalent or superior.

The identified substitute part MX3AWT-A1-0000-000BB1 shares identical mechanical and optical specifications but operates at different electrical parameters (3.7V forward voltage, 350mA test current), requiring circuit redesign for voltage and current regulation.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (No Circuit Modification): The MX3SWT-A1-0000-000AB9 is obsolete with no direct pin-compatible substitute maintaining identical electrical specifications. Any replacement requires circuit redesign.

For Active Product Status: The MX3AWT-A1-0000-000BB1 is the CreeLED equivalent in the active XLamp® MX series. This part is RoHS compliant and available in production quantities with Tape & Reel packaging, supporting high-volume manufacturing. However, the 7V lower forward voltage and 3× higher test current necessitate complete power supply and current-limiting circuit redesign.

Mechanical & Optical Compatibility: Both parts share identical 2-SMD package geometry, footprint dimensions, and 120° viewing angle, eliminating PCB layout modifications.

Thermal & Environmental Equivalence: Both parts maintain 11°C/W thermal resistance and MSL 2A moisture sensitivity, ensuring equivalent thermal management and handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the MX3AWT-A1-0000-000BB1 be used as a direct drop-in replacement for the MX3SWT-A1-0000-000AB9?

A: No. While both parts share identical mechanical packaging and optical specifications (5.00mm × 5.00mm footprint, 120° viewing angle), the electrical parameters differ significantly. The substitute operates at 3.7V forward voltage and 350mA test current compared to the original 10.7V and 115mA. Circuit redesign for voltage regulation and current limiting is required.

Q: Are the PCB footprints identical between these two parts?

A: Yes. Both parts use 2-SMD, Gull Wing Exposed Pad packaging with 5.00mm × 5.00mm dimensions and 1.48mm maximum seated height. No PCB layout modifications are necessary for mechanical compatibility.

Q: What is the luminous flux difference between these parts?

A: The MX3AWT-A1-0000-000BB1 produces 97 lumens (94–100 lm range) at 350mA compared to 91 lumens (87–94 lm range) at 115mA for the original part. The substitute delivers approximately 6% higher flux output.

Q: Does the substitute part meet RoHS compliance?

A: Yes. The MX3AWT-A1-0000-000BB1 is RoHS compliant. The original MX3SWT-A1-0000-000AB9 RoHS status is not specified in available documentation.

Q: Are moisture sensitivity and thermal characteristics equivalent?

A: Yes. Both parts maintain MSL 2A (4 Weeks) moisture sensitivity level and 11°C/W thermal resistance, ensuring equivalent handling, storage, and thermal management requirements.

Q: What is the primary reason for substitution?

A: The MX3SWT-A1-0000-000AB9 is classified as obsolete. The MX3AWT-A1-0000-000BB1 is the active equivalent from CreeLED's current XLamp® MX product line, ensuring long-term availability and production support.
