Key Parameters

Substitute Part Grouping Explanation

Substitution of the XPCWHT-L1-0000-00G50 is determined by strict alignment of the following critical parameters:

Mandatory Compatibility Parameters:

• Color and CCT: White, Cool 6200K
• Package / Case: 1414 (3535 Metric)
• Mounting Type: Surface Mount
• CRI: 70 (Typ)
• Flux @ 25°C, 350mA: 135 lm (range 130–139 lm)
• Test Current: 350mA

Allowable Variation Parameters:

• Forward Voltage (Vf): ±0.1V tolerance acceptable for circuit design flexibility
• Viewing Angle: ±5° variation acceptable for optical design compatibility
• Lumens/Watt: ±5 lm/W variation acceptable for efficiency comparison
• Maximum Current: Higher ratings acceptable for thermal margin
• Thermal Resistance: Lower values acceptable for improved thermal performance

Engineering Selection Recommendations

XPGWHT-L1-0000-00G51 as Direct Substitute:

The XPGWHT-L1-0000-00G51 is a valid parametric equivalent for the XPCWHT-L1-0000-00G50 based on the following engineering criteria:

1. Electrical Compatibility: Forward voltage difference of 0.1V is within standard circuit design tolerance for LED driver circuits. Both parts operate at identical test current (350mA) and deliver identical luminous flux (135 lm) at 25°C.

2. Mechanical Compatibility: Identical package format (1414/3535 Metric), footprint dimensions (3.45 × 3.45 mm), and height (2.13 mm) ensure direct PCB layout compatibility without redesign.

3. Optical Compatibility: Viewing angle increase from 120° to 125° represents a 5° expansion within acceptable optical design variation for most applications.

4. Thermal Performance: Thermal resistance reduction from 8°C/W to 4°C/W provides improved heat dissipation, reducing junction temperature under identical operating conditions.

5. Efficiency Gain: Lumens/Watt improvement from 129 to 133 lm/W represents a 3.1% efficiency gain at rated current.

6. Product Status & Compliance: Both parts are Active status. The substitute offers documented RoHS Compliance and REACH Unaffected status, providing regulatory advantage for applications requiring environmental compliance documentation.

7. Current Rating Margin: Maximum current rating increase from 500mA to 1500mA provides additional thermal and electrical design margin for future application scaling.

Frequently Asked Questions (FAQ)

Q1: Can XPGWHT-L1-0000-00G51 be used as a direct replacement for XPCWHT-L1-0000-00G50 without circuit modification?

A: Yes. Both parts share identical luminous flux (135 lm), test current (350mA), color (White 6200K), CRI (70), and package format (1414/3535 Metric). The forward voltage difference of 0.1V is within standard LED driver tolerance and does not require circuit redesign for most applications.

Q2: What is the impact of the 0.1V forward voltage difference?

A: The XPGWHT-L1-0000-00G51 operates at 2.9V versus 3.0V for the main part. This 3.3% reduction in forward voltage results in proportionally lower power dissipation at identical current. LED driver circuits with voltage regulation headroom (typical designs include 0.5–1.0V margin) accommodate this variation without adjustment.

Q3: Does the increased viewing angle (125° vs. 120°) affect optical design?

A: The 5° increase in viewing angle represents a 4.2% expansion of the light distribution cone. For applications requiring specific beam geometry, this variation may require optical modeling validation. For general illumination applications with diffusers or secondary optics, this difference is negligible.

Q4: What advantage does the improved thermal resistance (4°C/W vs. 8°C/W) provide?

A: Lower thermal resistance improves heat transfer from the LED junction to the PCB. At identical operating current and ambient temperature, the XPGWHT-L1-0000-00G51 operates with approximately 4°C lower junction temperature, extending operational life and maintaining color stability over extended use cycles.

Q5: Are there any compliance or regulatory differences between the two parts?

A: The XPGWHT-L1-0000-00G51 provides documented RoHS Compliance and REACH Unaffected status. Applications requiring environmental compliance certification should specify the substitute part. The main part does not list these certifications in the provided data.

Q6: Can the higher maximum current rating (1500mA vs. 500mA) of the substitute be utilized?

A: The substitute's higher maximum current rating provides design margin but does not change the test current specification (350mA). Operating the substitute at currents above 350mA requires independent thermal and optical validation and is outside the scope of direct substitution equivalence.

Q7: Is inventory availability a factor in substitution selection?

A: Yes. The substitute part (XPGWHT-L1-0000-00G51) has 15,609 units in stock versus 1,057 units for the main part, providing significantly improved supply chain availability for high-volume production or long-term procurement planning.
