XRCWHT-L1-0000-00907 LED XLamp® XR-C White 3529 SMD Equivalent & Substitute Parts

Part Overview

The XRCWHT-L1-0000-00907 is a CreeLED XLamp® XR-C white surface mount LED in 3529 (9073 metric) package configuration. This part is classified as obsolete and operates at 4.6V forward voltage with 350mA test current, delivering 84 lumens at 25°C. Due to its obsolete product status, direct replacement with active production equivalents from the XLamp® XR-E series is necessary for new designs and ongoing procurement requirements.

Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-00907 is determined by the following critical parameters:

Mechanical Compatibility: Package type (3529/9073 metric), mounting type (surface mount), and physical dimensions (9.00mm × 7.00mm footprint, 4.60mm max height) must remain identical for PCB layout compatibility.

Electrical Compatibility: Test current (350mA), luminous flux output (84 lm at 25°C within 81–87 lm range), viewing angle (90°), and color (white) establish functional equivalence. Forward voltage tolerance is acceptable within the range of 3.3V to 4.6V for typical LED circuit designs.

Regulatory & Environmental Compliance: RoHS compliance, REACH unaffected status, and MSL 4 rating must be maintained.

All substitute parts listed below are from the active XLamp® XR-E series, which shares identical mechanical packaging, electrical performance at rated current, and regulatory compliance with the obsolete XR-C part. The XR-E series offers improved thermal resistance (8°C/W vs. 12°C/W) and higher efficiency (73 lm/W vs. 69 lm/W), with forward voltage reduced to 3.3V typical.

Engineering Selection Recommendations

All listed XLamp® XR-E substitute parts are active production components with full regulatory compliance (RoHS compliant, REACH unaffected). The primary advantage of XR-E substitutes is improved thermal performance (8°C/W vs. 12°C/W) and higher luminous efficiency (73 lm/W vs. 69 lm/W) while maintaining identical mechanical packaging and luminous output at rated current.

The forward voltage reduction from 4.6V to 3.3V requires circuit verification to confirm compatibility with existing current-limiting resistor or driver designs. For applications with fixed voltage supplies, recalculation of series resistance or driver adjustment may be necessary.

XREWHT-L1-0000-00901 offers extended color temperature range (5000K–10000K cool white) and higher maximum current rating (1A vs. 500mA), with specified CRI of 75 typical. This part is suitable for applications requiring color temperature flexibility and higher current capability.

All remaining XR-E variants (XREWHT-L1-0000-00905, 00907, 00908, 00909, 00910, 00937, 009B1, 009B2, 009B3) provide identical electrical and thermal performance with active product status and full inventory availability.

Frequently Asked Questions (FAQ)

Q: Can XREWHT XR-E parts directly replace XRCWHT XR-C parts without circuit modification?

A: Mechanical and thermal compatibility is direct due to identical 3529 package dimensions and mounting type. However, forward voltage differs (3.3V vs. 4.6V). Circuits using fixed current sources or PWM drivers are compatible. Circuits with fixed series resistors require recalculation to maintain 350mA test current.

Q: What is the significance of the thermal resistance improvement from 12°C/W to 8°C/W?

A: Lower thermal resistance improves heat dissipation from the LED junction to the PCB. This reduces junction temperature at equivalent power dissipation, extending LED lifespan and maintaining color stability over operating life.

Q: Are all XR-E substitutes electrically interchangeable at 350mA test current?

A: Yes. All listed XR-E parts deliver 84 lumens (81–87 lm range) at 350mA and 25°C, with identical 90° viewing angle and 3529 package configuration. Differences in part number suffix reflect internal binning or manufacturing date codes, not functional performance.

Q: What is the difference between XREWHT-L1-0000-00901 and other XR-E variants?

A: XREWHT-L1-0000-00901 specifies extended color temperature range (5000K–10000K cool white) with CRI 75 typical, and maximum current rating of 1A. Other variants do not specify CCT or CRI parameters. For applications requiring neutral or warm white output, verify CCT specifications with the manufacturer.

Q: Is packaging format (Tape & Reel vs. bulk) a substitution constraint?

A: Packaging format affects procurement and handling but not electrical or mechanical compatibility. All listed substitutes are available in Tape & Reel format suitable for automated assembly. Bulk packaging availability should be confirmed with the supplier.

Q: Do all substitute parts meet the same moisture sensitivity and compliance requirements?

A: Yes. All XR-E substitutes maintain MSL 4 (72 hours), RoHS compliance, and REACH unaffected status identical to the original XRCWHT part.
