Key Parameters

Substitute Part Grouping Explanation

Substitute parts are qualified based on the following critical parameters that determine functional compatibility:

Mechanical Compatibility:

• Package / Case: 3529 (9073 Metric) — identical across all substitutes
• Size / Dimension: 0.354" L x 0.276" W (9.00mm x 7.00mm) — identical across all substitutes
• Height - Seated (Max): 0.181" (4.60mm) — identical across all substitutes
• Mounting Type: Surface Mount — identical across all substitutes

Electrical Compatibility:

• Flux @ 25°C, 350mA: 59lm (57lm ~ 62lm) — identical across all substitutes
• Current - Test: 350mA — identical across all substitutes
• Viewing Angle: 90° — identical across all substitutes
• Color: White — maintained across all substitutes

Compliance & Environmental:

• RoHS Status: RoHS Compliant — maintained across all substitutes
• Moisture Sensitivity Level (MSL): 4 (72 Hours) — identical across all substitutes
• REACH Status: REACH Unaffected — identical across all substitutes

All substitute parts are from the active XLamp® XR-E product line, ensuring ongoing availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are from the active XLamp® XR-E product line and maintain RoHS Compliance and REACH Unaffected status, ensuring regulatory continuity with the obsolete XRCWHT-L1-0000-005B9.

Primary Substitutes (Highest Availability): XREWHT-L1-0000-005B9, XREWHT-L1-R250-005B7, and XREWHT-L1-0000-005B7 offer the highest inventory levels (929 Pcs, 1048 Pcs, and 989 Pcs respectively) and active product status.

Alternative Substitutes: XREWHT-L1-0000-005E8 provides warm white color temperature specification at 2700K with active status and 917 Pcs inventory. All remaining XREWHT variants maintain identical mechanical and electrical compatibility with inventory levels ranging from 697 to 1048 pieces.

Thermal Performance Consideration: Substitute parts feature improved thermal resistance (8°C/W) compared to the main part (12°C/W), resulting in lower junction temperatures at equivalent operating currents.

Forward Voltage Difference: Substitute parts operate at 3.3V typical forward voltage versus 4.6V for the main part. Circuit designs must accommodate this 0.2V reduction in LED forward voltage drop.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-005B9 directly replace XRCWHT-L1-0000-005B9 in existing designs?

A: Yes. Both parts share identical mechanical package (3529 / 9073 Metric), identical flux output (59lm at 350mA), identical viewing angle (90°), and identical test current (350mA). The primary design consideration is the 0.2V reduction in forward voltage (3.3V vs 4.6V), which may require minor current-limiting resistor adjustment in constant-voltage driver circuits.

Q: What is the difference between XREWHT-L1-0000-005B9 and XREWHT-L1-R250-005B9?

A: Both parts are electrically and mechanically identical. The "R250" designation in the part number indicates a different reel configuration or manufacturing lot code. Functional performance and package specifications are equivalent.

Q: Why do some substitute parts show "—" for Current - Max?

A: Parts designated with "R250" in the part number do not have Current - Max specifications provided in the available data. However, all parts maintain identical test current (350mA) and flux output specifications, ensuring functional compatibility at the specified operating point.

Q: Is XREWHT-L1-0000-005E8 suitable as a substitute?

A: Yes. XREWHT-L1-0000-005E8 is functionally compatible and additionally specifies warm white color temperature at 2700K with CRI 80 (Typ). This part is suitable for applications requiring color temperature specification. All mechanical and electrical parameters remain compatible with the main part.

Q: Are all substitute parts RoHS Compliant?

A: Yes. All substitute parts maintain RoHS Compliant status and REACH Unaffected status, ensuring regulatory compliance equivalent to the main part.

Q: What is the impact of improved thermal resistance in substitute parts?

A: Substitute parts feature 8°C/W thermal resistance versus 12°C/W in the main part. This represents improved thermal performance, resulting in lower junction temperatures at equivalent operating currents. This is a beneficial characteristic for thermal management in LED applications.
