Equivalent & Substitute Parts for XREWHT-L1-0000-007F4

Part Overview

The CreeLED XLamp® XR-E White Neutral LED (XREWHT-L1-0000-007F4) is an active-status surface-mount light-emitting diode designed for general illumination applications requiring neutral white color temperature. This part operates at 3.3V forward voltage with a 350mA test current and delivers 71 lumens at 25°C, achieving 61 lumens per watt efficiency. The 4750K correlated color temperature and 75 CRI provide balanced spectral output suitable for commercial and residential lighting systems. Substitute parts are identified based on matching electrical characteristics, mechanical compatibility, and thermal performance within the XLamp® XR-E product family.

Substitute Part Grouping Explanation

Substitution eligibility for the XREWHT-L1-0000-007F4 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility: Forward voltage (3.3V typical), test current (350mA), and maximum current rating (700mA) must match exactly. Lumens per watt efficiency (61 lm/W) and flux output at 25°C (71 lumens, 67–74 lumen range) establish functional performance equivalence.

Optical Characteristics: Color rendering index (75 typical) and viewing angle (90°) must be identical. Correlated color temperature (CCT) may vary within the neutral white family (4300K–4750K range) while maintaining neutral white classification and equivalent spectral performance.

Mechanical & Thermal Compatibility: Package type (3529 / 9073 Metric), mounting type (Surface Mount), physical dimensions (9.00 × 7.00 mm footprint, 4.60 mm maximum seated height), and thermal resistance (8°C/W) must match to ensure PCB compatibility and thermal management equivalence.

Regulatory & Compliance Alignment: RoHS compliance status, moisture sensitivity level (MSL 4), and product status (Active) must be identical to ensure supply chain continuity and manufacturing process compatibility.

The substitute part XREWHT-L1-0000-007F5 meets all substitution criteria with the exception of CCT, which is specified at 4300K rather than 4750K. This variation remains within the neutral white category and maintains all other electrical, optical, mechanical, and thermal parameters.

Parameter Comparison

Engineering Selection Recommendations

Both XREWHT-L1-0000-007F4 and XREWHT-L1-0000-007F5 are active-status products manufactured by CreeLED, Inc., and carry identical RoHS compliance and MSL ratings. Selection between these parts is determined by correlated color temperature requirement:

XREWHT-L1-0000-007F4 (4750K): Select this part for applications requiring warmer neutral white output. The 4750K CCT provides increased red spectrum content suitable for warm-toned illumination environments.

XREWHT-L1-0000-007F5 (4300K): Select this part for applications requiring cooler neutral white output. The 4300K CCT provides increased blue spectrum content suitable for cool-toned or daylight-balanced illumination environments.

Both parts deliver identical electrical performance (3.3V, 350mA test current, 61 lm/W), optical quality (75 CRI, 90° viewing angle), mechanical compatibility (3529 package, 9.00 × 7.00 mm footprint), and thermal characteristics (8°C/W). Substitution is electrically and mechanically transparent; selection is driven by color temperature specification only.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-007F5 be used as a direct replacement for XREWHT-L1-0000-007F4 on existing PCBs?

A: Yes. Both parts share identical package type (3529 / 9073 Metric), footprint dimensions (9.00 × 7.00 mm), seated height (4.60 mm maximum), and mounting type (Surface Mount). No PCB layout modifications are required. The only difference is correlated color temperature (4300K vs. 4750K).

Q: What is the significance of the CCT difference between these parts?

A: Correlated color temperature (CCT) defines the perceived color of white light. The 4750K variant (XREWHT-L1-0000-007F4) produces warmer white light with more red spectrum content. The 4300K variant (XREWHT-L1-0000-007F5) produces cooler white light with more blue spectrum content. Both remain within the neutral white classification. Selection depends on the intended lighting application and color temperature specification.

Q: Are the electrical operating parameters identical between these parts?

A: Yes. Both parts operate at 3.3V forward voltage (typical), accept 350mA test current, support 700mA maximum current, and deliver 61 lumens per watt efficiency. Flux output at 25°C is identical (71 lumens, 67–74 lumen range). Electrical substitution is complete.

Q: Do both parts meet the same compliance and regulatory requirements?

A: Yes. Both XREWHT-L1-0000-007F4 and XREWHT-L1-0000-007F5 are RoHS compliant, carry MSL 4 (72 Hours) moisture sensitivity rating, and maintain active product status. Supply chain and manufacturing process compatibility is equivalent.

Q: What thermal management considerations apply to both parts?

A: Both parts feature identical thermal resistance of 8°C/W. Thermal design calculations, heat sink requirements, and PCB thermal management strategies are equivalent between the two parts. No thermal redesign is necessary when substituting.
