Key Parameters

Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-007E4 is determined by the following critical parameters:

Mechanical Compatibility:

• Package type: 3529 (9073 Metric) surface mount
• Footprint dimensions: 0.354" L x 0.276" W (9.00mm x 7.00mm)
• Maximum seated height: 0.181" (4.60mm)
• Mounting type: Surface Mount

Optical Compatibility:

• Color: White, Neutral
• Viewing angle: 90°
• Flux output @ 25°C, 350mA test current: 71lm (67lm ~ 74lm range)
• CRI: 75 (Typ)

Electrical Compatibility:

• Test current: 350mA
• Forward voltage tolerance: 3.3V to 4.6V acceptable range
• Maximum current rating: minimum 500mA

Color Temperature Tolerance:

• Primary specification: 4500K
• Acceptable range: 4000K to 4300K (within neutral white spectrum for general lighting applications)

Regulatory & Environmental:

• RoHS Compliant
• MSL 4 (72 Hours)
• REACH Unaffected
• ECCN: EAR99

All substitute parts listed below meet these criteria and are from the active XLamp® XR-E series, providing improved thermal characteristics (8°C/W vs. 12°C/W) and higher maximum current ratings (700mA vs. 500mA).

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: XREWHT-L1-0000-007E4

This part provides the closest color temperature match (4500K) to the original XRCWHT-L1-0000-007E4. It is from the active XLamp® XR-E series with RoHS compliance and identical optical and mechanical specifications. The forward voltage is 0.2V lower (3.3V vs. 4.6V), which is within acceptable tolerance for neutral white LED applications. Thermal resistance is improved (8°C/W vs. 12°C/W), and maximum current rating is increased to 700mA, providing design margin for future applications.

Secondary Substitutes: XREWHT-L1-0000-007F5 and XREWHT-L1-R250-007F5

These parts operate at 4300K, within the neutral white spectrum. Both are active products with identical flux output, CRI, and mechanical compatibility. The R250 variant indicates a different packaging reel specification but maintains the same electrical and optical performance.

Tertiary Substitutes: XREWHT-L1-0000-007E5 and XREWHT-L1-R250-007E5

These parts operate at 4000K, at the cooler end of the neutral white range. Both are active products with full compatibility to the original part's mechanical and optical specifications.

All substitute parts are RoHS Compliant, REACH Unaffected, and carry MSL 4 (72 Hours) rating, matching the original part's regulatory status.

Frequently Asked Questions (FAQ)

Q: Can I use XREWHT-L1-0000-007E4 as a direct replacement for XRCWHT-L1-0000-007E4?

A: Yes. Both parts share identical package (3529), footprint dimensions (9.00mm x 7.00mm), height (4.60mm), viewing angle (90°), flux output (71lm at 350mA), and CRI (75). The forward voltage difference (3.3V vs. 4.6V) is within acceptable tolerance for neutral white LED circuits. The XR-E variant offers improved thermal performance (8°C/W vs. 12°C/W) and higher maximum current (700mA vs. 500mA).

Q: What is the difference between the 4500K, 4300K, and 4000K versions?

A: All three color temperatures fall within the neutral white spectrum and produce identical flux output (71lm) at the test current of 350mA. The 4500K version (XREWHT-L1-0000-007E4) most closely matches the original part's color temperature. The 4300K and 4000K versions are acceptable substitutes where slight color temperature variation is tolerable in the application.

Q: What does the "R250" designation in part numbers XREWHT-L1-R250-007E5 and XREWHT-L1-R250-007F5 indicate?

A: The R250 designation refers to the packaging reel specification. These parts are supplied on 250mm reels in Tape & Reel format. The electrical and optical specifications are identical to their non-R250 counterparts. Selection between R250 and standard reel variants depends on your assembly equipment and volume requirements.

Q: Are all substitute parts RoHS Compliant?

A: Yes. All substitute parts listed (XREWHT series) are RoHS Compliant, REACH Unaffected, and carry ECCN EAR99 classification, matching the regulatory status of the original XRCWHT-L1-0000-007E4.

Q: What is the thermal resistance improvement in the XR-E series?

A: The XLamp® XR-E series (all substitute parts) has thermal resistance of 8°C/W compared to 12°C/W in the original XR-C part. This 33% improvement in thermal performance allows for better heat dissipation and supports higher operating currents (700mA maximum vs. 500mA maximum).

Q: Can I use these parts interchangeably in existing PCB designs?

A: Yes. All substitute parts use the identical 3529 (9073 Metric) surface mount package with matching footprint dimensions (0.354" L x 0.276" W) and maximum seated height (0.181"). No PCB layout modifications are required. Circuit design should account for the lower forward voltage (3.3V) of the XR-E series when calculating current-limiting resistor values.

Q: What inventory levels are available for each substitute part?

A: Current inventory levels are: XREWHT-L1-0000-007E4 (1041 Pcs), XREWHT-L1-0000-007F5 (3784 Pcs), XREWHT-L1-0000-007E5 (933 Pcs), XREWHT-L1-R250-007F5 (1039 Pcs), and XREWHT-L1-R250-007E5 (860 Pcs). All parts are new original stock.
