XMLBWT-00-0000-000HT20Z6 LED XLamp® XM-L2 Warm White 3500K Equivalent & Substitute Parts

Part Overview

The XMLBWT-00-0000-000HT20Z6 is a CreeLED XLamp® XM-L2 warm white LED with a correlated color temperature of 3500K, designed for surface mount applications in the 2020 (5050 metric) package. This component delivers 210 lumens at 85°C under 700mA test current with a forward voltage of 2.72V and maintains an active product status. Substitute parts become necessary when the primary component experiences supply constraints, inventory depletion, or when design requirements permit operation within the electrical and mechanical tolerances of alternative manufacturers' offerings.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the XMLBWT-00-0000-000HT20Z6 is determined by the following critical parameters:

Mechanical Compatibility: Package type (2020/5050 metric), physical dimensions (5.00mm x 5.00mm), and mounting type (surface mount) must match exactly to ensure PCB footprint compatibility.

Electrical Compatibility: Forward voltage range, maximum current rating, and test current specifications must fall within acceptable operating margins for the circuit design. The substitute must not exceed the maximum current rating of the primary part's driver circuit.

Optical Characteristics: Color temperature (CCT), color rendering index (CRI), and luminous flux output determine functional equivalence. Substitutes with different CCT values (such as cool white at 5000K versus warm white at 3500K) represent functional alternatives rather than direct equivalents, as they produce visibly different light output.

Regulatory Compliance: RoHS and REACH compliance status must be verified to meet applicable regional requirements.

The identified substitute parts PSL0102WBEB1 and PSL0102WBEC1 share identical mechanical specifications (2020 package, 5.00mm x 5.00mm dimensions) and surface mount mounting type. However, both substitutes operate at 5000K (cool white) rather than 3500K (warm white), represent a different optical characteristic class, and carry obsolete product status compared to the active status of the primary part.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Availability: The XMLBWT-00-0000-000HT20Z6 maintains active product status with 1079 units in stock, making it the preferred selection for new designs and production runs.

Substitute Consideration Constraints: Both PSL0102WBEB1 and PSL0102WBEC1 carry obsolete product status, indicating discontinued manufacturing and limited future availability. These parts should be considered only when primary part supply is exhausted and design requirements permit operation at reduced current levels (120mA test current versus 700mA for the primary part) and higher forward voltage (3.3V versus 2.72V).

Color Temperature Mismatch: The substitutes operate at 5000K (cool white) rather than 3500K (warm white). This represents a fundamental optical characteristic difference and is suitable only for applications where color temperature flexibility is acceptable or where the application specifically requires cool white output.

Electrical Derating: The maximum current rating of the substitutes (200mA) is significantly lower than the primary part (3A). Circuit designs must be verified to operate within the 120mA test current specification of the substitutes.

Compliance Status: Both substitutes meet ROHS3 compliance and REACH unaffected status, maintaining regulatory alignment with the primary part.

Frequently Asked Questions (FAQ)

Q: Can PSL0102WBEB1 or PSL0102WBEC1 be used as direct replacements for XMLBWT-00-0000-000HT20Z6?

A: These parts share identical mechanical specifications (2020 package, 5.00mm x 5.00mm footprint) and surface mount mounting type, enabling PCB-level physical compatibility. However, they are not direct electrical equivalents due to differences in forward voltage (3.3V versus 2.72V), test current (120mA versus 700mA), maximum current rating (200mA versus 3A), and color temperature (5000K cool white versus 3500K warm white). Circuit redesign or verification is required before substitution.

Q: Why do the substitute parts have lower maximum current ratings?

A: The PSL0102 series from ROHM Semiconductor is designed for lower-power applications with a maximum current rating of 200mA, compared to the XLamp® XM-L2 series maximum of 3A. This reflects different product positioning and thermal design within each manufacturer's portfolio.

Q: Are the substitute parts still available for purchase?

A: Both PSL0102WBEB1 and PSL0102WBEC1 carry obsolete product status, indicating discontinued manufacturing. While inventory may exist in distribution channels (2638 and 1627 units respectively are noted as in stock), future availability cannot be guaranteed. The primary part XMLBWT-00-0000-000HT20Z6 maintains active status with confirmed current inventory.

Q: What is the significance of the color temperature difference between 3500K and 5000K?

A: Color temperature is a fundamental optical characteristic. 3500K (warm white) produces light with a warmer, more yellowish appearance suitable for residential and hospitality applications. 5000K (cool white) produces light with a cooler, more bluish appearance suitable for commercial and task lighting. These are not interchangeable for applications where specific color temperature is required.

Q: How do the CRI values compare between the primary and substitute parts?

A: The primary part XMLBWT-00-0000-000HT20Z6 has a CRI of 80. PSL0102WBEB1 also has a CRI of 80, while PSL0102WBEC1 has a higher CRI of 90. Higher CRI values indicate better color rendering accuracy. For applications requiring high color fidelity, PSL0102WBEC1 offers superior performance in this parameter.

Q: What does the height difference (3.15mm versus 1.00mm) mean for PCB assembly?

A: The primary part has a seated height of 3.15mm, while both substitutes have a seated height of 1.00mm. This difference affects PCB clearance requirements and may impact thermal management design. Lower profile components may offer advantages in space-constrained applications but require verification of thermal performance in the specific circuit design.
