Substitute Part Grouping Explanation

Substitution for the MLCSWT-H1-0000-000XE1 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Series: XLamp® ML-C
• Package / Case: 4-SMD, J-Lead Exposed Pad
• Size / Dimension: 0.138" L x 0.124" W (4.60mm x 3.15mm)
• Height - Seated (Max): 0.052" (1.33mm)
• Forward Voltage (Vf) Typical: 6.4V
• Test Current: 50mA
• Maximum Current: 175mA
• Viewing Angle: 120°
• Thermal Resistance: 13°C/W
• Mounting Type: Surface Mount
• RoHS Status: RoHS Compliant
• MSL Rating: 2A (4 Weeks)

Allowable Variation Parameters:

• CCT (K): Cool white range (5000K – 6500K)
• CRI (Color Rendering Index): 75 – 80
• Luminous Flux @ 25°C: 27lm – 31lm
• Lumens/Watt @ Test Current: 91 lm/W (consistent across variants)

The two identified substitutes meet all mandatory parameters while operating within allowable variations for color temperature and color rendering index.

Parameter Comparison

Engineering Selection Recommendations

MLCSWT-A1-0000-000X51 is the direct functional equivalent with identical 6500K color temperature and 80 CRI specification. This part carries Active product status, ensuring ongoing manufacturer support and supply chain availability. Selection of this part eliminates obsolescence risk while maintaining exact color and rendering characteristics.

MLCSWT-H1-0000-000XE3 is a parametric equivalent with 5000K color temperature instead of 6500K. This part also carries Active product status. The 5000K specification represents a cooler white point shift of 1500K and a CRI specification of 80 (matching the original). This part is suitable for applications where the cooler color temperature is acceptable or preferred, and where the 1500K shift does not impact system performance or user perception.

Both substitute parts maintain identical electrical characteristics (6.4V forward voltage, 50mA test current, 175mA maximum current), mechanical compatibility (4-SMD J-Lead package, 4.60mm x 3.15mm footprint, 1.33mm height), and thermal properties (13°C/W). Both are RoHS Compliant with 2A MSL rating.

Frequently Asked Questions (FAQ)

Q: Can MLCSWT-A1-0000-000X51 be used as a direct replacement for MLCSWT-H1-0000-000XE1?

A: Yes. Both parts share identical electrical specifications (6.4V, 50mA test current), mechanical package (4-SMD J-Lead, 4.60mm x 3.15mm), color temperature (6500K), and CRI (80). The MLCSWT-A1-0000-000X51 carries Active product status, providing supply continuity.

Q: What is the difference between MLCSWT-H1-0000-000XE3 and the original part?

A: The MLCSWT-H1-0000-000XE3 differs only in color temperature: 5000K versus 6500K. All other parameters—forward voltage, current ratings, luminous flux, CRI, package dimensions, and thermal characteristics—are identical. This part is suitable where a cooler white point is acceptable.

Q: Are all three parts mechanically interchangeable?

A: Yes. All three parts use the identical 4-SMD J-Lead Exposed Pad package with 4.60mm x 3.15mm footprint and 1.33mm seated height. PCB layout and reflow profiles remain unchanged.

Q: What is the significance of "Not For New Designs" status on the original part?

A: This designation indicates the MLCSWT-H1-0000-000XE1 has reached end-of-life. New product development should use the Active-status substitutes (MLCSWT-A1-0000-000X51 or MLCSWT-H1-0000-000XE3) to ensure long-term supply availability and manufacturer support.

Q: Do the substitute parts meet the same compliance requirements?

A: Yes. Both MLCSWT-A1-0000-000X51 and MLCSWT-H1-0000-000XE3 are RoHS Compliant with 2A MSL rating (4 Weeks), matching the original part's compliance profile.

Q: Which substitute should be selected for color-critical applications?

A: MLCSWT-A1-0000-000X51 maintains the exact 6500K color temperature and 80 CRI of the original part, making it the appropriate choice for applications where color consistency is required. MLCSWT-H1-0000-000XE3 introduces a 1500K shift to 5000K and should only be used where this cooler color temperature is acceptable.
