Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-00709 is determined by the following critical parameters that must remain compatible:

Mechanical Compatibility:

Package / Case: 3529 (9073 Metric) — all substitute parts maintain identical footprint and height
Mounting Type: Surface Mount — all substitutes are surface mount devices
Size / Dimension: 0.354" L × 0.276" W (9.00 mm × 7.00 mm) — identical across all parts
Height - Seated (Max): 0.181" (4.60 mm) — identical across all parts

Electrical Compatibility:

Flux @ 25°C, 350mA: 71 lm (67–74 lm) — all substitute parts maintain this luminous flux range
Test Current: 350 mA — all substitute parts are rated for this current
Viewing Angle: 90° — all substitute parts maintain this viewing angle
Color: White — all substitute parts are white LEDs

Regulatory & Environmental:

RoHS Compliant — all substitute parts maintain RoHS compliance
Moisture Sensitivity Level (MSL): 4 (72 Hours) — all substitute parts maintain this rating
REACH Status: REACH Unaffected — all substitute parts maintain this status

The substitute parts transition from the obsolete XLamp® XR-C series to the active XLamp® XR-E series. While forward voltage differs slightly (3.3V vs. 4.6V) and thermal resistance improves (8°C/W vs. 12°C/W), these changes are within acceptable design margins for direct substitution in existing applications.

Engineering Selection Recommendations

All listed substitute parts are active production components from CreeLED, Inc., ensuring ongoing availability and supply chain stability. The transition from XLamp® XR-C to XLamp® XR-E series maintains full mechanical and electrical compatibility within the specified parameter ranges.

XREWHT-L1-0000-00801 is suitable for applications requiring enhanced luminous flux (77 lm at 350 mA) and higher efficiency (67 lm/W). This part specifies a correlated color temperature range of 5000K–10000K (cool white) and includes a CRI of 75 (Typ), making it appropriate for color-critical applications.

XREWHT-L1-0000-007B1, XREWHT-L1-0000-007B3, XREWHT-L1-0000-007B5 are parametric equivalents maintaining the original 71 lm flux specification at 350 mA. These parts are differentiated by color temperature binning (neutral white and warm white variants) and are suitable for direct replacement in existing designs without circuit modification.

All substitute parts maintain RoHS compliance and REACH unaffected status, ensuring regulatory conformance. The improved thermal resistance of XLamp® XR-E devices (8°C/W vs. 12°C/W) provides enhanced thermal performance in the same package footprint.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-00801 be used as a direct replacement for XRCWHT-L1-0000-00709?

A: Yes. Both parts share identical mechanical dimensions (3529 package, 9.00 mm × 7.00 mm footprint, 4.60 mm height), identical viewing angle (90°), and compatible electrical ratings at 350 mA test current. The forward voltage difference (3.3V vs. 4.6V) is within typical design margins. The higher luminous flux (77 lm vs. 71 lm) and improved efficiency represent performance enhancement rather than incompatibility.

Q: What is the difference between XREWHT-L1-0000-007B1, XREWHT-L1-0000-007B3, and XREWHT-L1-0000-007B5?

A: These parts are parametric equivalents with identical electrical and mechanical specifications. The suffix designations indicate color temperature binning within the white LED spectrum (neutral white vs. warm white). Selection depends on the specific color temperature requirement of the application. All three maintain 71 lm flux at 350 mA and are mechanically interchangeable.

Q: Are there any circuit design changes required when substituting from XRCWHT-L1-0000-00709 to XLamp® XR-E parts?

A: The 0.2V forward voltage reduction (4.6V to 3.3V) may require minor current-limiting resistor adjustment in series-resistor-driven circuits to maintain identical LED current. For current-source or regulated driver circuits, no modification is necessary. Thermal design benefits from the improved thermal resistance (8°C/W vs. 12°C/W) of XLamp® XR-E devices.

Q: Do all substitute parts maintain the same moisture sensitivity level?

A: Yes. All substitute parts maintain MSL 4 (72 Hours) rating, identical to the original XRCWHT-L1-0000-00709. Storage and handling procedures remain unchanged.

Q: Which substitute part should be selected for maximum luminous flux?

A: XREWHT-L1-0000-00801 provides the highest luminous flux at 77 lm (74–81 lm range) at 350 mA test current, representing a 6 lm increase over the original part. This part also specifies the highest efficiency at 67 lm/W and includes defined color temperature (5000K–10000K) and CRI (75 Typ) parameters.
