Key Parameters

Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-00AE4 is based on the following criteria:

Electrical Compatibility:

• Color temperature: Neutral white (4000K–4500K range)
• Luminous flux: 91 lm at test current (87–94 lm range)
• Test current: 350mA
• CRI: 75 (Typ)
• Viewing angle: 90°

Mechanical Compatibility:

• Package / Case: 3529 (9073 Metric)
• Mounting type: Surface Mount
• Physical dimensions: 0.354" L × 0.276" W (9.00mm × 7.00mm)
• Height - Seated (Max): 0.181" (4.60mm)

Regulatory & Environmental:

• RoHS Compliant
• MSL: 4 (72 Hours)
• REACH Unaffected

All substitute parts listed are from the active XLamp® XR-E series and meet these criteria. Variations in forward voltage (3.3V vs. 4.6V) and maximum current rating (700mA vs. 500mA) are within acceptable substitution parameters for this product category. Thermal resistance improvements in XR-E variants (8°C/W vs. 12°C/W) provide enhanced thermal performance.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Exact CCT Match - 4500K):

• XREWHT-L1-0000-00AE4 (Tape & Reel packaging)
• XREWHT-L1-R250-00AE4 (Tape & Reel packaging with R250 specification)

These parts provide identical color temperature (4500K) and luminous flux characteristics. All substitute parts are from the active XLamp® XR-E product line, ensuring long-term availability and supply chain continuity.

Secondary Substitutes (Adjacent CCT Range - 4000K to 4300K):

• XREWHT-L1-0000-00AE5 (4000K)
• XREWHT-L1-0000-00AF5 (4300K)
• XREWHT-L1-R250-00AE5 (4000K, Tape & Reel)
• XREWHT-L1-R250-00AF5 (4300K, Tape & Reel)

These parts operate within the neutral white spectrum and maintain identical luminous flux, CRI, and mechanical compatibility. Selection depends on application-specific color temperature requirements.

Compliance & Regulatory: All substitute parts maintain RoHS Compliance, MSL Level 4 (72 Hours), and REACH Unaffected status, ensuring regulatory alignment with the original part.

Performance Improvements: XLamp® XR-E substitutes offer improved thermal resistance (8°C/W vs. 12°C/W) and higher maximum current rating (700mA vs. 500mA), providing enhanced thermal management and operational headroom in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1-0000-00AE4 directly replace XRCWHT-L1-0000-00AE4 in existing designs?

A: Yes. Both parts share identical color temperature (4500K), luminous flux (91 lm at 350mA), CRI (75 Typ), viewing angle (90°), and mechanical specifications (3529 package, 9.00mm × 7.00mm × 4.60mm). The forward voltage difference (3.3V vs. 4.6V) requires circuit verification to ensure current-limiting resistor or driver compatibility. The improved thermal resistance (8°C/W) of the XR-E variant is beneficial for thermal management.

Q: What is the difference between parts with and without "R250" in the part number?

A: The "R250" designation indicates a specific tape and reel packaging specification. Both XREWHT-L1-0000-00AE4 and XREWHT-L1-R250-00AE4 are electrically and mechanically identical; the difference is in packaging format for automated assembly. Select based on your manufacturing process requirements.

Q: Can I use XREWHT-L1-0000-00AE5 (4000K) instead of the 4500K original part?

A: XREWHT-L1-0000-00AE5 is electrically and mechanically compatible and maintains identical luminous flux and CRI. The color temperature difference (4000K vs. 4500K) is a 500K shift within the neutral white spectrum. Application suitability depends on color temperature requirements; verify that 4000K meets your lighting design specifications.

Q: Are all substitute parts currently in stock?

A: Inventory status is provided in the part data. XREWHT-L1-0000-00AE4 has 1111 Pcs available; XREWHT-L1-0000-00AE5 has 1104 Pcs; XREWHT-L1-0000-00AF5 has 820 Pcs; XREWHT-L1-R250-00AE4 has 887 Pcs; XREWHT-L1-R250-00AE5 has 1086 Pcs; XREWHT-L1-R250-00AF5 has 886 Pcs. Confirm current availability with your supplier.

Q: What are the thermal implications of switching from XR-C to XR-E?

A: The XR-E variant has superior thermal resistance (8°C/W vs. 12°C/W), meaning lower junction temperature rise for the same power dissipation. This improves LED lifespan and color stability, particularly in high-ambient-temperature applications. No circuit redesign is required; this is a performance benefit.

Q: Do all substitute parts meet the same regulatory requirements?

A: Yes. All substitute parts are RoHS Compliant, MSL Level 4 (72 Hours), and REACH Unaffected, matching the regulatory profile of the original XRCWHT-L1-0000-00AE4.
