Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria applied strictly to the provided parameters:

Primary Compatibility Criteria:

Color: White, Neutral (required match)
CCT: 4500K or adjacent binned values (4300K, 4250K acceptable within neutral white range)
Package / Case: 1414 (3535 Metric) (mandatory match)
Mounting Type: Surface Mount (required match)
Test Current: 350mA (standard operating point)
Flux Range: 130–139 lm @ 25°C, 350mA (electrical equivalence)
CRI: 70 (Typ) (matching color rendering)

Secondary Compatibility Considerations:

Forward Voltage (Vf): 2.85V–3V range (circuit design tolerance)
Maximum Current: ≥350mA (operational headroom)
Viewing Angle: 115°–125° (application-dependent)
Thermal Resistance: ≤8°C/W (thermal management compatibility)
Product Status: Active preferred (obsolete parts not suitable as long-term substitutes)

Substitute parts are grouped by electrical equivalence (flux, current, voltage) and mechanical compatibility (package, dimensions, thermal characteristics). CCT variations within the neutral white spectrum (4000K–4500K) are included where flux and electrical parameters align.

Engineering Selection Recommendations

Recommended Primary Substitutes (Active Status, RoHS Compliant):

The XLamp® XP-G series (XPGWHT-01-0000-00GC2, XPGWHT-01-0000-00GD2, XPGWHT-01-0000-00GE4) provides direct electrical equivalence with identical flux output (135 lm), matching CCT (4500K), and improved thermal performance (4°C/W vs. 6°C/W). All XP-G variants are active products with RoHS compliance certification. The lower forward voltage (2.9V vs. 3.0V) reduces power dissipation and improves circuit efficiency.

Secondary Substitutes (Active Status, Electrical Equivalence):

The XLamp® XT-E (XTEAWT-00-0000-00000BGE4) maintains flux equivalence and 4500K CCT with RoHS compliance. The 2.85V forward voltage and 1.5A maximum current rating provide enhanced design margin. Viewing angle reduction from 120° to 115° requires application-specific validation.

The XLamp® XP-C (XPCWHT-L1-0000-00GE4) matches forward voltage (3.0V) and viewing angle (120°) with identical flux and CCT. Maximum current rating of 0.5A limits high-current applications. Thermal resistance of 8°C/W equals the original part specification.

CCT Variants (4000K–4300K):

XPGWHT-01-0000-00GE5 (4000K) and XPGWHT-01-0000-00GC3 (4300K) maintain electrical equivalence with identical flux and current ratings. Selection depends on application color temperature tolerance.

Tape & Reel Packaging:

All substitute parts are available in Tape & Reel (TR) packaging suitable for automated assembly. The original part packaging format is not specified in the provided data.

Frequently Asked Questions (FAQ)

Q: Can XPGWHT-01-0000-00GD2 directly replace XPEHEW-01-0000-00GD2 in existing designs?

A: Yes, within circuit design constraints. Both parts deliver 135 lm at 350mA with 4500K CCT in the 1414 (3535 Metric) package. The forward voltage difference (2.9V vs. 3.0V) requires verification that the LED driver or current source accommodates the lower voltage. The improved thermal resistance (4°C/W vs. 6°C/W) is beneficial for thermal management.

Q: What is the significance of the CCT variants (4000K, 4300K, 4500K)?

A: Color Correlated Temperature (CCT) defines the perceived color of white light. 4000K appears cooler (more blue) than 4500K. All variants maintain identical flux output (135 lm) and electrical parameters. Selection depends on application requirements for color appearance. The 4500K variants (XPGWHT-01-0000-00GD2, XPGWHT-01-0000-00GE4) match the original part's color specification.

Q: Why is thermal resistance important in LED substitution?

A: Thermal resistance (°C/W) determines junction temperature rise under operating current. Lower values indicate better heat dissipation. The XP-G series (4°C/W) dissipates heat more efficiently than the original XP-E HEW (6°C/W), reducing thermal stress and extending operational life. Circuit board thermal design must accommodate the specific thermal resistance of the selected part.

Q: Are all substitute parts RoHS compliant?

A: The XLamp® XP-G series and XT-E are certified RoHS Compliant. The XP-C variant does not specify RoHS status in the provided data. Regulatory compliance requirements should be verified against application standards before final selection.

Q: What is the difference between XPGWHT-01-0000-00GC2 and XPGWHT-01-R250-00GC2?

A: Both parts are electrically and mechanically identical XLamp® XP-G LEDs with 4500K CCT and 135 lm flux. The designation difference (R250) indicates a specific tape reel configuration for automated pick-and-place assembly. Selection depends on manufacturing equipment compatibility.

Q: Can the XT-E (XTEAWT-00-0000-00000BGE4) be used if viewing angle is critical?

A: The XT-E provides 115° viewing angle compared to the original 120°. This 5° reduction may affect light distribution in applications requiring wide angular coverage. Optical simulation or prototype testing is necessary to confirm suitability for angle-dependent applications.

Q: What is the maximum current rating, and why does it vary across substitutes?

A: Maximum current ratings (0.5A–1.5A) define the absolute current limit for safe operation. The original part (1A max) and XP-G series (1.5A max) support higher current operation than the XP-C (0.5A max). Circuit design must ensure operating current does not exceed the selected part's maximum rating to prevent thermal runaway or premature failure.
