Key Parameters

Substitute Part Grouping Explanation

Substitution of XRCWHT-L1-0000-007F4 is determined by the following critical parameters:

Mechanical Compatibility: All substitute parts maintain identical package type (3529/9073 Metric), physical dimensions (9.00mm x 7.00mm), and mounting height (4.60mm), ensuring direct PCB compatibility without layout modifications.

Electrical Compatibility: Substitute parts operate at 350mA test current with forward voltage of 3.3V (compared to 4.6V for the original part). This 0.2V reduction is within typical circuit design margins for LED driver circuits. All substitutes maintain 90° viewing angle and neutral white color classification.

Optical Performance: All substitute parts deliver 71lm (67lm ~ 74lm) at 25°C and 350mA, matching the original part's luminous flux specification. CCT variations (4000K to 4750K) fall within the neutral white category and are selectable based on application requirements.

Thermal Characteristics: XLamp® XR-E substitutes feature improved thermal resistance (8°C/W versus 12°C/W), providing superior thermal performance in the same package footprint.

Regulatory Compliance: All parts maintain RoHS compliance, MSL 4 rating, and identical REACH/ECCN classifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Exact CCT Match): XREWHT-L1-0000-007F4 is the direct equivalent for XRCWHT-L1-0000-007F4, maintaining 4750K CCT specification. This part is active status with improved thermal characteristics (8°C/W versus 12°C/W) and higher efficiency (61 lm/W versus 58 lm/W). Forward voltage reduction from 4.6V to 3.3V requires LED driver circuit verification but is within standard design tolerances.

Alternative CCT Options: XREWHT-L1-0000-007F5 (4300K) and XREWHT-L1-0000-007E4 (4500K) provide neutral white alternatives within the same luminous flux range. Selection depends on application color temperature requirements. XREWHT-L1-0000-007E5 (4000K) extends the neutral white range toward cooler tones.

Tape & Reel Variants: XREWHT-L1-R250-007E5 and XREWHT-L1-R250-007F5 are functionally identical to their standard packaging counterparts, differentiated only by reel configuration for high-volume manufacturing.

Compliance Assurance: All substitute parts maintain RoHS compliance and MSL 4 rating, ensuring compatibility with standard PCB assembly processes and environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-007F4 directly replace XRCWHT-L1-0000-007F4 without circuit modifications?

A: Direct PCB replacement is possible due to identical package dimensions and mounting characteristics. However, LED driver circuits must accommodate the 0.2V forward voltage reduction (4.6V to 3.3V). Constant-current drivers typically tolerate this variation without adjustment. Constant-voltage circuits may require resistor value recalculation to maintain target current.

Q: What is the difference between standard and Tape & Reel (R250) packaging?

A: Functional and electrical specifications are identical. Tape & Reel packaging is configured for automated high-volume assembly with 250-unit reel configuration. Standard packaging (TR designation) is also supplied on tape and reel. Selection depends on manufacturing volume and equipment compatibility.

Q: Are all substitute parts available in active production status?

A: Yes. All XLamp® XR-E substitutes (XREWHT series) are active status parts. The original XRCWHT-L1-0000-007F4 is obsolete, making active substitutes necessary for new designs and production continuity.

Q: How does the thermal resistance improvement affect circuit design?

A: Improved thermal resistance (8°C/W versus 12°C/W) reduces junction temperature rise for equivalent power dissipation. This allows higher current operation or improved reliability in thermally constrained applications. No circuit redesign is required; the improvement is beneficial.

Q: Can I select a different CCT (color temperature) substitute?

A: Yes. XREWHT-L1-0000-007E4 (4500K), XREWHT-L1-0000-007E5 (4000K), and XREWHT-L1-0000-007F5 (4300K) are electrically and mechanically compatible. CCT selection depends on application lighting requirements. All maintain identical luminous flux (71lm) and viewing angle (90°).

Q: What is the inventory status of substitute parts?

A: XREWHT-L1-0000-007F5 (4300K) has the highest inventory at 3784 units. XREWHT-L1-0000-007A2 (4750K) has 1113 units. All active substitutes maintain stock availability for production requirements.
