Engineering Selection Recommendations
Direct Equivalent (4750K, Active Production):
XPEWHT-01-0000-00FD1 and XPEWHT-01-R250-00FD1 are direct equivalents with identical CCT (4750K), flux (126 lm), test current (350mA), and package specifications. Both are RoHS Compliant and in active production. The primary difference is packaging format (standard Tape & Reel vs. R250 reel specification). Forward voltage is 3.05V versus 3V on the main part, representing a 0.05V increase within acceptable design tolerance. Thermal resistance is 9°C/W versus 6°C/W on the main part; thermal design review is required for applications with strict thermal constraints.
Alternative Equivalent (4750K, Different Series):
XTEAWT-00-0000-00000BFD1 (XLamp® XT-E series) matches 4750K CCT and 126 lm flux at 350mA test current. Forward voltage is 2.85V, representing a 0.15V decrease from the main part. Maximum current rating is 1.5A versus 1A. Thermal resistance is 5°C/W, superior to the main part. Viewing angle is 115° versus 120°. This part is RoHS Compliant and in active production with higher inventory availability (1113 units).
Parametric Equivalent (4750K, XP-C Series):
XPCWHT-L1-0000-00FF4 (XLamp® XP-C series) matches 4750K CCT, 126 lm flux, and 3V forward voltage. Maximum current is 500mA versus 1A on the main part, limiting high-current applications. Height is 0.084" (2.13mm) versus 0.087" (2.21mm), requiring PCB layout verification. Thermal resistance is 8°C/W. This part is in active production with 1035 units in stock.
Adjacent CCT Equivalents (4500K, 4300K):
XPEWHT-01-0000-00FD2, XPEWHT-01-R250-00FD2, XPEWHT-01-0000-00FC2, XPEWHT-01-R250-00FC2, XPEWHT-01-0000-00FC3, and XPEWHT-01-R250-00FC3 provide parametric equivalence with adjacent CCT values (4500K or 4300K). All maintain 126 lm flux at 350mA, 3.05V forward voltage, 1A maximum current, and 115° viewing angle. These parts are RoHS Compliant and in active production. CCT selection depends on application color temperature requirements.
Frequently Asked Questions (FAQ)
Q: Can XPEWHT-01-0000-00FD1 directly replace XPEHEW-01-0000-00FD1 without design changes?
A: XPEWHT-01-0000-00FD1 is a direct parametric equivalent with matching CCT (4750K), flux (126 lm), test current (350mA), and package (1414). Forward voltage increases from 3V to 3.05V; verify driver circuit compliance. Thermal resistance increases from 6°C/W to 9°C/W; thermal design review is required for high-power or thermally constrained applications. Height decreases from 2.21mm to 2.13mm; verify PCB clearance.
Q: What is the difference between XPEWHT-01-0000-00FD1 and XPEWHT-01-R250-00FD1?
A: Both parts are electrically and mechanically identical. The difference is packaging format: XPEWHT-01-0000-00FD1 uses standard Tape & Reel, while XPEWHT-01-R250-00FD1 uses R250 reel specification. Selection depends on assembly equipment compatibility and procurement requirements.
Q: Why does XTEAWT-00-0000-00000BFD1 have lower forward voltage (2.85V) than the main part (3V)?
A: XTEAWT-00-0000-00000BFD1 belongs to the XLamp® XT-E series, which has different semiconductor architecture than the XLamp® XP-E HEW series. The 0.15V reduction is within normal manufacturing variation across product families. Driver circuits must be verified for compatibility with the lower voltage specification.
Q: Can I use XPCWHT-L1-0000-00FF4 in applications requiring 1A maximum current?
A: No. XPCWHT-L1-0000-00FF4 has a maximum current rating of 500mA, limiting operation to half the current capability of the main part. This part is suitable only for applications operating at or below 500mA.
Q: What is the impact of 115° viewing angle (substitute parts) versus 120° (main part)?
A: The 5° reduction in viewing angle represents a minor optical difference. Most substitute parts (XTEAWT, XPEWHT series) specify 115° versus the main part's 120°. Application-specific optical design review is required to determine if this difference affects light distribution requirements.
Q: Are all substitute parts RoHS Compliant?
A: XTEAWT-00-0000-00000BFD1, XPEWHT series parts, and XPEWHT-01-R250 series parts are RoHS Compliant. XPCWHT-L1-0000-00FF4 RoHS status is not specified in the provided data. Verify compliance requirements with your procurement or quality department.
Q: How do I select between 4750K, 4500K, and 4300K CCT options?
A: CCT selection is application-dependent. 4750K is neutral white with higher blue content. 4500K is warm neutral white. 4300K is warmer neutral white. All three maintain identical flux (126 lm), current (350mA), and CRI (70). Select based on desired color temperature for the end application.
