Substitute Part Grouping Explanation

Substitution eligibility for the MLCSWT-A1-0000-000XA4 is determined by strict equivalence across the following critical parameters:

• Color and CCT: White, Neutral 4000K (exact match required)
• Electrical Performance: Forward voltage 6.4V, test current 50mA, maximum current 175mA
• Optical Output: 29lm nominal flux at 25°C and 50mA test current
• Luminous Efficiency: 91 lm/W at specified test conditions
• Color Rendering: CRI 80 (Typ)
• Mechanical Compatibility: 4-SMD J-Lead Exposed Pad package, 4.60mm x 3.15mm footprint, 1.33mm maximum seated height
• Thermal Characteristics: 13°C/W thermal resistance
• Compliance: RoHS Compliant, MSL 2A rating

Only parts matching all these parameters across the XLamp® ML-C series qualify as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both the MLCSWT-A1-0000-000XA4 and MLCSWT-A1-0000-000XE5 are active products from CreeLED with identical electrical, optical, and mechanical specifications. Selection between these parts should be based on inventory availability and procurement lead times. Both parts carry RoHS Compliance certification and identical MSL 2A ratings, ensuring equivalent reliability and environmental compliance for production environments. The MLCSWT-A1-0000-000XE5 currently maintains higher inventory levels (2115 pcs vs. 819 pcs), which may provide supply chain advantages for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can MLCSWT-A1-0000-000XE5 be used as a direct replacement for MLCSWT-A1-0000-000XA4?

A: Yes. Both parts are parametrically equivalent across all electrical, optical, and mechanical specifications. They share identical forward voltage (6.4V), test current (50mA), flux output (29lm), color temperature (4000K), package geometry (4-SMD J-Lead Exposed Pad, 4.60mm x 3.15mm), and thermal characteristics (13°C/W).

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

A: No. Both parts carry identical RoHS Compliance status, REACH Unaffected designation, and MSL 2A (4 Weeks) ratings. They are equivalent from a regulatory and environmental compliance perspective.

Q: What determines substitution eligibility for XLamp® ML-C 4000K LEDs?

A: Substitution requires exact matching of color temperature (4000K), forward voltage (6.4V), test current (50mA), flux output (29lm nominal), CRI (80 Typ), viewing angle (120°), package type (4-SMD J-Lead Exposed Pad), physical dimensions (4.60mm x 3.15mm footprint, 1.33mm max height), and thermal resistance (13°C/W).

Q: Can parts with different CCT values substitute for the MLCSWT-A1-0000-000XA4?

A: No. Color temperature is a critical parameter. Only 4000K neutral white variants within the XLamp® ML-C series qualify as substitutes. Different CCT values (such as 3000K warm white or 5000K cool white) are not interchangeable.

Q: Are there inventory considerations when selecting between these substitute parts?

A: Yes. The MLCSWT-A1-0000-000XE5 has higher current inventory (2115 pcs) compared to the MLCSWT-A1-0000-000XA4 (819 pcs). For applications requiring immediate availability or high-volume procurement, the higher-inventory part may offer supply chain advantages without compromising performance.
