XMLBWT-00-0000-000HT40E6 Equivalent & Substitute Parts

Part Overview

The XMLBWT-00-0000-000HT40E6 is a CreeLED XLamp® XM-L2 warm white LED (3500K) in 2020 (5050 Metric) surface mount package. This part is currently active in production with 865 units in stock. The XM-L2 series delivers high luminous efficacy at 123 lm/W with a forward voltage of 2.72V at 700mA test current. Substitute parts may be required due to supply constraints, design revisions, or application-specific performance requirements where alternative color temperatures or electrical characteristics are acceptable.

Substitute Part Grouping Explanation

The substitute parts PSL0102WBEB1 and PSL0102WBEC1 are ROHM Semiconductor PSL0102 series LEDs in the same 2020 (5050 Metric) package. Substitution is based on the following allowed parameters:

• Package compatibility: Both substitute parts use the identical 2020 (5050 Metric) surface mount package with matching footprint dimensions (5.00mm x 5.00mm)
• Mounting type: All parts are surface mount compatible
• Physical height: Substitute parts have a maximum seated height of 0.039" (1.00mm), which is lower than the main part at 0.124" (3.15mm), allowing board-level compatibility
• Color rendering: Both substitute parts maintain CRI of 80 or higher, meeting color quality requirements
• Compliance: All parts are RoHS3 compliant and REACH unaffected

The primary difference is color temperature: the main part operates at 3500K (warm white), while substitutes operate at 5000K (cool white). This represents a shift in correlated color temperature and requires application-level validation.

Parameter Comparison

Engineering Selection Recommendations

The XMLBWT-00-0000-000HT40E6 is an active product with current manufacturing support. Both substitute parts (PSL0102WBEB1 and PSL0102WBEC1) are marked as obsolete, indicating discontinued production status.

PSL0102WBEC1 offers superior color rendering at CRI 90 compared to the main part and PSL0102WBEB1 at CRI 80. However, both substitute parts operate at significantly reduced current levels (120mA test vs. 700mA) and lower maximum current ratings (200mA vs. 3A), resulting in substantially lower luminous output and efficacy.

Selection between PSL0102WBEB1 and PSL0102WBEC1 depends on color rendering requirements: PSL0102WBEB1 provides 38lm at 95 lm/W, while PSL0102WBEC1 provides 30lm at 75 lm/W with enhanced color accuracy. Both require circuit redesign to accommodate the higher forward voltage (3.3V vs. 2.72V) and lower operating current.

Frequently Asked Questions (FAQ)

Q: Can PSL0102WBEB1 or PSL0102WBEC1 be used as direct drop-in replacements for XMLBWT-00-0000-000HT40E6?

A: No. While all three parts share the same 2020 (5050 Metric) package footprint, the substitute parts require circuit modifications. The forward voltage differs (3.3V vs. 2.72V), test current is significantly lower (120mA vs. 700mA), and maximum current rating is reduced (200mA vs. 3A). Driver and power supply adjustments are necessary.

Q: What is the primary difference between PSL0102WBEB1 and PSL0102WBEC1?

A: Both are PSL0102 series parts with identical electrical specifications at test current. The key difference is color rendering index: PSL0102WBEC1 provides CRI 90 versus PSL0102WBEB1 at CRI 80. PSL0102WBEB1 delivers higher luminous flux (38lm vs. 30lm) and efficacy (95 lm/W vs. 75 lm/W).

Q: Why do the substitute parts have lower luminous output than the main part?

A: The XMLBWT-00-0000-000HT40E6 operates at 700mA test current with a maximum rating of 3A, enabling high-power operation. The PSL0102 series is designed for lower-power applications at 120mA test current with a 200mA maximum rating. Output scales with operating current.

Q: Are there thermal considerations when substituting these parts?

A: The main part specifies thermal resistance of 2.5°C/W. Thermal resistance data for substitute parts is not provided. The lower operating current of PSL0102 series parts results in reduced thermal dissipation requirements, which may simplify thermal management in low-power applications.

Q: What is the impact of the color temperature shift from 3500K to 5000K?

A: The main part provides warm white light at 3500K. Both substitute parts operate at 5000K (cool white), representing a shift toward higher color temperature. This affects perceived light quality and may not be suitable for applications requiring warm white illumination.

Q: Are both substitute parts still available for procurement?

A: Both PSL0102WBEB1 and PSL0102WBEC1 are marked as obsolete products. Current inventory availability is 2638 units (PSL0102WBEB1) and 1627 units (PSL0102WBEC1), but future procurement may be limited due to discontinued production status.
