XRCWHT-L1-0000-005A7 Equivalent & Substitute Parts

Part Overview

The XRCWHT-L1-0000-005A7 is a CreeLED XLamp® XR-C warm white LED (3250K) in 3529 SMD package format. This part is classified as obsolete. Due to its discontinued status, direct replacement with active production equivalents from the XLamp® XR-E series is necessary to maintain supply chain continuity and ensure long-term component availability for new designs and production runs.

Substitute Part Grouping Explanation

Substitution of the XRCWHT-L1-0000-005A7 is determined by the following critical parameters:

Mechanical Compatibility:

Package / Case: 3529 (9073 Metric) — all substitutes maintain identical footprint and height
Mounting Type: Surface Mount — all substitutes are surface mount compatible
Size / Dimension: 0.354" L x 0.276" W (9.00mm x 7.00mm) — identical across all parts
Height - Seated (Max): 0.181" (4.60mm) — identical across all parts

Electrical Compatibility:

Color: White, Warm — all substitutes maintain warm white spectrum
Flux @ 25°C, 350mA: 59lm (57lm ~ 62lm) — identical luminous flux range
Test Current: 350mA — identical operating current
Viewing Angle: 90° — identical beam angle

Thermal & Compliance:

RoHS Compliant — all substitutes maintain RoHS compliance
MSL Rating: 4 (72 Hours) — identical moisture sensitivity level

Variable Parameter (CCT Selection):

CCT (K): Available in 2700K, 2850K, 3000K, and 3250K — selection depends on application color temperature requirement

The XLamp® XR-E series substitutes (XREWHT-L1 variants) provide active production status while maintaining mechanical and thermal compatibility. Forward voltage differs slightly (3.3V vs. 4.6V) and thermal resistance improves (8°C/W vs. 12°C/W), both favorable characteristics for circuit design.

Engineering Selection Recommendations

All substitute parts listed maintain active production status with CreeLED, Inc., ensuring long-term availability and supply chain stability. Each substitute is RoHS compliant and carries identical MSL rating (4, 72 Hours), meeting regulatory and handling requirements equivalent to the original part.

For 3250K Color Temperature Requirement: Select XREWHT-L1-0000-005A7 (standard packaging) or XREWHT-L1-R250-005A7 (tape & reel packaging). Both maintain the original 3250K CCT specification with improved thermal performance (8°C/W vs. 12°C/W) and higher maximum current rating (700mA vs. 500mA).

For Alternative Color Temperatures:

3000K: XREWHT-L1-0000-005A8 or XREWHT-L1-R250-005A8
2850K: XREWHT-L1-0000-005A9 or XREWHT-L1-R250-005A9
2700K: XREWHT-L1-0000-005AA or XREWHT-L1-R250-005AA

Packaging Selection: Standard packaging (XREWHT-L1-0000-) is suitable for manual assembly and small-volume production. Tape & reel packaging (XREWHT-L1-R250-) is specified for automated pick-and-place assembly and high-volume manufacturing.

The forward voltage reduction from 4.6V to 3.3V requires circuit verification to confirm compatibility with existing current-limiting resistor or driver designs. The improved thermal resistance (8°C/W) reduces junction temperature rise under identical operating conditions.

Frequently Asked Questions (FAQ)

Q: Can XREWHT-L1 series parts directly replace XRCWHT-L1-0000-005A7 on existing PCBs?

A: Yes. All substitute parts maintain identical mechanical dimensions (0.354" L x 0.276" W, 9.00mm x 7.00mm), height (0.181", 4.60mm), and 3529 SMD package footprint. PCB layout and solder pad geometry require no modification.

Q: What is the impact of the 0.2V forward voltage difference (4.6V vs. 3.3V)?

A: The lower forward voltage of XR-E substitutes reduces power dissipation in series resistors or current-limiting circuits. Existing designs using fixed current sources are unaffected. Designs using fixed resistors will deliver slightly higher LED current; circuit simulation or testing is necessary to confirm acceptable performance within the 350mA test current specification.

Q: Are tape & reel packaged parts (XREWHT-L1-R250-) electrically identical to standard packaged parts (XREWHT-L1-0000-)?

A: Yes. Tape & reel packaging affects only the physical delivery format and handling method. Electrical specifications, thermal characteristics, and performance are identical between packaging variants. Selection depends on assembly process requirements.

Q: Which substitute should be selected if the application requires 3250K color temperature?

A: XREWHT-L1-0000-005A7 (standard packaging) or XREWHT-L1-R250-005A7 (tape & reel packaging) maintain the original 3250K CCT specification. Both are active production parts with identical luminous flux (59lm at 350mA) and viewing angle (90°).

Q: Does the improved thermal resistance (8°C/W vs. 12°C/W) require design changes?

A: No design changes are required. The lower thermal resistance of XR-E substitutes is a performance improvement that reduces junction temperature under identical operating conditions. Existing thermal management provisions remain adequate.

Q: Are all substitute parts RoHS compliant?

A: Yes. All XREWHT-L1 series substitutes are RoHS compliant with identical MSL rating (4, 72 Hours) as the original XRCWHT-L1-0000-005A7 part.
