Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-006B3 is based on the following criteria:

Mechanical Compatibility: All substitute parts maintain identical package type (3529/9073 Metric), physical dimensions (9.00mm x 7.00mm), and maximum seated height (4.60mm), ensuring PCB footprint and assembly compatibility.

Electrical Compatibility: All substitute parts operate at the same test current (350mA), produce identical luminous flux at 25°C (65lm ±3lm range), and maintain the same viewing angle (90°). These parameters ensure equivalent optical performance in the application.

Thermal Characteristics: Substitute parts from the XLamp® XR-E series feature improved thermal resistance (8°C/W vs. 12°C/W), providing enhanced thermal performance.

Forward Voltage Consideration: Substitute parts operate at 3.3V typical forward voltage, compared to 4.6V for the original part. This 0.2V reduction is within typical circuit design tolerance for LED applications and does not preclude substitution.

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

Engineering Selection Recommendations

All listed XLamp® XR-E substitute parts are classified as active products with full manufacturing support and availability. The XRCWHT-L1-0000-006B3 original part is obsolete and no longer manufactured.

Primary Substitute: XREWHT-L1-0000-006B3 is the direct parametric equivalent, maintaining identical part designation structure within the XR-E series. This part is actively produced and stocked.

Alternative Substitutes: XREWHT-L1-0000-006B1, XREWHT-L1-0000-006B2, XREWHT-L1-0000-006B4, XREWHT-L1-0000-006B5, XREWHT-L1-0000-006B6, XREWHT-L1-0000-006B7, XREWHT-L1-0000-006B8, and XREWHT-L1-0000-006B9 are all functionally equivalent. These parts share identical electrical performance (350mA test current, 65lm flux output, 90° viewing angle) and mechanical compatibility (3529 package, 9.00mm x 7.00mm footprint).

Regulatory Compliance: All substitute parts maintain RoHS compliance and MSL Level 4 moisture sensitivity rating, consistent with the original part. REACH and ECCN classifications are identical across all parts.

Thermal Performance: XLamp® XR-E substitutes provide improved thermal resistance (8°C/W) compared to the original XR-C part (12°C/W), resulting in lower junction temperatures under identical operating conditions.

Forward Voltage: The 0.2V reduction in typical forward voltage (3.3V vs. 4.6V) is within standard LED circuit design margins and does not preclude direct substitution in existing designs.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-006B3 directly replace XRCWHT-L1-0000-006B3 on existing PCBs?

A: Yes. Both parts use identical 3529 (9073 Metric) surface mount packages with matching footprints (9.00mm x 7.00mm) and maximum seated heights (4.60mm). No PCB layout modifications are required.

Q: What is the difference between the XR-C and XR-E series?

A: The original part belongs to the XLamp® XR-C series, which is obsolete. The XLamp® XR-E series provides equivalent optical and electrical performance with improved thermal characteristics (8°C/W vs. 12°C/W). Both series use the same 3529 package format.

Q: Does the 0.2V forward voltage difference affect circuit operation?

A: No. The reduction from 4.6V to 3.3V typical forward voltage is within standard LED circuit design tolerance. Most LED driver circuits and current-limiting resistor designs accommodate this variation without modification.

Q: Are all listed substitute parts electrically identical?

A: Yes. All substitute parts operate at 350mA test current, produce 65lm luminous flux at 25°C, and maintain 90° viewing angle. They are electrically interchangeable for the specified operating conditions.

Q: What is the packaging difference between the main part and substitutes?

A: The original part is supplied in bulk packaging. Most substitute parts are available in Tape & Reel (TR) format for automated assembly. Both packaging formats contain identical components; the difference is in handling and assembly method only.

Q: Are there any compliance or certification differences?

A: No. All parts maintain identical RoHS compliance, MSL Level 4 rating, REACH status, and ECCN classification (EAR99). Regulatory requirements are fully satisfied by any substitute part.

Q: Which substitute part should be selected for new designs?

A: XREWHT-L1-0000-006B3 is recommended as the primary choice due to direct part number alignment within the XR-E series. All other listed substitutes are functionally equivalent and may be selected based on availability or inventory considerations.
