Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the XPCWHT-L1-0000-00G51 is determined by the following criteria:

Critical Matching Parameters:

• Color Temperature (CCT): 6200K (Cool White)
• Flux Output @ 25°C, 350mA: 135 lumens (130–139 lm range)
• Color Rendering Index (CRI): 70 (Typ)
• Package / Case: 1414 (3535 Metric)
• Mounting Type: Surface Mount
• Physical Dimensions: 3.45 × 3.45 mm footprint, 2.13 mm maximum height

Allowable Variation Parameters:

• Forward Voltage (Vf): Within circuit design tolerance (±0.3V acceptable for most applications)
• Viewing Angle: ±5° variation acceptable
• Maximum Current Rating: Higher ratings acceptable if test current remains 350mA
• Thermal Resistance: Lower values acceptable (improved thermal performance)

The XPGWHT-L1-0000-00G51 qualifies as a parametric equivalent because it maintains identical CCT, flux output, CRI, and package specifications while offering improved thermal characteristics and higher maximum current capability.

Parameter Comparison

Engineering Selection Recommendations

XPCWHT-L1-0000-00G51 (Main Part):

• Select when XLamp® XP-C series specification is required by design documentation
• Product status is Active with established supply (691 units in stock)
• Suitable for applications with thermal management capacity for 8°C/W junction-to-case resistance

XPGWHT-L1-0000-00G51 (Substitute Part):

• Select when improved thermal performance is required (4°C/W thermal resistance vs. 8°C/W)
• Select when higher maximum current capability (1.5A vs. 500mA) provides design margin
• Select when RoHS Compliance and REACH Unaffected status are mandatory requirements
• Provides superior lumens-per-watt efficiency (133 lm/W vs. 129 lm/W) at identical test current
• Wider viewing angle (125° vs. 120°) suitable for broader light distribution applications
• Larger available inventory (15,609 units) supports higher-volume production requirements

Both parts maintain identical optical output (135 lumens at 6200K, CRI 70) and mechanical compatibility (1414 package, 3.45 × 3.45 mm footprint, 2.13 mm height). Forward voltage difference (3.0V vs. 2.9V) is within typical circuit design tolerance for LED driver circuits.

Frequently Asked Questions (FAQ)

Q: Can XPGWHT-L1-0000-00G51 directly replace XPCWHT-L1-0000-00G51 in existing designs?

A: Yes, for applications where the XLamp® XP-C series is not explicitly specified. Both parts share identical package (1414), footprint (3.45 × 3.45 mm), height (2.13 mm), color temperature (6200K), flux output (135 lm), and CRI (70). The 0.1V forward voltage difference (3.0V vs. 2.9V) is within standard LED driver tolerance. Verify circuit design allows for the substitute's lower thermal resistance (4°C/W vs. 8°C/W), which may reduce junction temperature.

Q: What is the significance of the thermal resistance difference?

A: The XPGWHT-L1-0000-00G51 has 4°C/W thermal resistance compared to 8°C/W for the XPCWHT-L1-0000-00G51. Lower thermal resistance indicates more efficient heat transfer from the LED junction to the package case. This reduces junction temperature at identical operating current, extending component life and maintaining color stability. Applications with limited thermal management benefit from the substitute's superior thermal characteristics.

Q: Are there viewing angle implications for substitution?

A: The XPGWHT-L1-0000-00G51 provides 125° viewing angle versus 120° for the main part. This 5° difference results in slightly broader light distribution. For applications requiring precise beam control or narrow-angle illumination, verify that the wider angle does not exceed optical design specifications. For general illumination, this difference is negligible.

Q: What compliance advantages does the substitute offer?

A: The XPGWHT-L1-0000-00G51 is certified RoHS Compliant and REACH Unaffected. If your application or market requires these certifications, the substitute meets these requirements. The main part's compliance status is not specified in available documentation.

Q: Does the higher maximum current rating of the substitute affect compatibility?

A: No. Both parts operate at identical test current (350mA). The XPGWHT-L1-0000-00G51's higher maximum current rating (1.5A vs. 500mA) provides additional design margin and does not affect operation at the specified 350mA test current. This higher rating may be advantageous for applications requiring future current increase capability.

Q: How do the lumens-per-watt ratings compare?

A: The XPGWHT-L1-0000-00G51 delivers 133 lm/W compared to 129 lm/W for the XPCWHT-L1-0000-00G51, both measured at 350mA test current. This 3% efficiency improvement reflects the XLamp® XP-G series' enhanced optical design. At identical operating current, the substitute produces equivalent light output with marginally lower power consumption.

Q: Are there supply chain considerations for substitution?

A: The XPGWHT-L1-0000-00G51 has significantly higher inventory availability (15,609 units vs. 691 units). For high-volume production or extended lead-time applications, the substitute's larger stock position may provide supply chain advantages.

Q: What parameters must remain identical for substitution to be valid?

A: Critical parameters that must match are color temperature (6200K), flux output (135 lumens at 25°C, 350mA), CRI (70), package type (1414), footprint (3.45 × 3.45 mm), and height (2.13 mm). These parameters define the component's functional and mechanical compatibility. All other parameters may vary within engineering tolerance.
