Parameter Comparison

Engineering Selection Recommendations

Direct Substitution Feasibility:

The MX6AWT-A1-R250-000BF7 is electrically and mechanically compatible at the package level but requires circuit-level evaluation due to the 20V to 3.3V forward voltage difference. This voltage reduction fundamentally alters the power supply and current limiting requirements in the application circuit.

Product Status Consideration:

The MX6SWT-H1-R250-000DF7 is obsolete, while MX6AWT-A1-R250-000BF7 is active. For new designs or long-term component availability, the active substitute is the appropriate choice. The substitute maintains identical optical characteristics (3200K, CRI 80, 120° viewing angle) and thermal properties (5°C/W, 1.48mm height).

Compliance and Certifications:

Both parts carry REACH Unaffected and ECCN EAR99 designations. The substitute additionally specifies RoHS Compliance, providing enhanced regulatory alignment for applications subject to RoHS requirements.

Thermal and Mechanical Compatibility:

Identical package footprint (5.00mm × 5.00mm), height (1.48mm), and thermal resistance (5°C/W) ensure direct PCB layout compatibility. The substitute's exposed pad variant may provide improved thermal performance in high-power applications.

Frequently Asked Questions (FAQ)

Q: Can MX6AWT-A1-R250-000BF7 be used as a direct drop-in replacement for MX6SWT-H1-R250-000DF7?

A: At the mechanical level, yes. Both parts share identical footprint dimensions (5.00mm × 5.00mm), height (1.48mm), and package type (2-SMD, Gull Wing). However, the forward voltage differs significantly (20V vs. 3.3V), requiring modification of the current-limiting circuit and power supply configuration. Electrical compatibility must be verified in the application circuit.

Q: What are the key optical differences between these parts?

A: Both parts deliver identical color temperature (3200K), color rendering index (CRI 80), and viewing angle (120°). The substitute produces 97 lumens versus 111 lumens at rated current, representing a 12.6% reduction in absolute flux. However, the substitute operates at 5× higher current (300mA vs. 60mA), resulting in superior lumens-per-watt efficiency (98 lm/W vs. 93 lm/W).

Q: Why does the substitute have a higher maximum current rating?

A: The MX6AWT-A1-R250-000BF7 operates at lower forward voltage (3.3V) and is designed for higher current operation (1A maximum vs. 175mA maximum). This reflects the different electrical architecture of the XLamp® MX-6 series compared to the MX-6S series.

Q: Are there packaging differences that affect thermal management?

A: The substitute features an exposed pad variant (Gull Wing Exposed Pad) compared to the standard Gull Wing package of the original part. Both maintain identical thermal resistance (5°C/W) and seated height (1.48mm). The exposed pad in the substitute may provide enhanced thermal coupling to the PCB in applications requiring maximum heat dissipation.

Q: What is the moisture sensitivity level for both parts?

A: Both parts carry MSL 2A rating with a 4-week floor life. This indicates identical moisture handling requirements and storage conditions.

Q: Is the substitute RoHS compliant?

A: Yes, MX6AWT-A1-R250-000BF7 is specified as RoHS Compliant. The original part does not specify RoHS status. For applications requiring RoHS compliance, the substitute meets this requirement.
