XMLBWT-00-0000-000PS50Z7 LED XLamp® XM-L2 Warm White 3000K Equivalent & Substitute Parts

Part Overview

The XMLBWT-00-0000-000PS50Z7 is a CreeLED XLamp® XM-L2 warm white LED with a correlated color temperature of 3000K, designed for surface mount applications in the 2020 (5050 metric) package. This component delivers 177 lm at 85°C under 700mA test current with a forward voltage of 2.72V and maintains active product status. Substitute parts become necessary when the primary component reaches end-of-life inventory depletion, supply chain constraints, or when design flexibility permits alternative color temperature specifications within compatible mechanical and electrical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the XMLBWT-00-0000-000PS50Z7 is constrained by the following critical parameters:

Mechanical Compatibility: Package type (2020/5050 metric), mounting type (surface mount), and physical dimensions (0.197" × 0.197" footprint) must remain identical to ensure PCB layout compatibility without redesign.

Electrical Compatibility: Forward voltage (Vf) and maximum current rating determine circuit design feasibility. The primary part operates at 2.72V typical with a 3A maximum rating. Substitute parts must operate within the same power supply and current-limiting circuit topology.

Optical Parameters: Color temperature (CCT), color rendering index (CRI), and luminous flux define the functional output. The primary part specifies warm white at 3000K with 85 CRI. Substitutes with different CCT values (such as cool white at 5000K) represent functional alternatives only when application requirements permit color temperature variation.

Compliance & Status: RoHS and REACH compliance ensure regulatory alignment. Product status (active vs. obsolete) indicates supply chain viability.

The identified substitute parts—PSL0102WBEB1 and PSL0102WBEC1 from ROHM Semiconductor—share identical package geometry and surface mount configuration but differ in color temperature (5000K cool white vs. 3000K warm white), forward voltage (3.3V vs. 2.72V), test current (120mA vs. 700mA), and luminous flux characteristics. These differences require circuit redesign and are suitable only for applications where cool white color temperature is acceptable.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (XMLBWT-00-0000-000PS50Z7): Maintain use of the primary part where supply is available. Active product status ensures long-term availability and consistent manufacturing specifications. RoHS compliance meets regulatory requirements for restricted substance control.

Substitute Consideration (PSL0102WBEB1 or PSL0102WBEC1): Both ROHM substitutes carry obsolete product status, indicating limited future availability and potential manufacturing discontinuation. Selection between these two requires evaluation of CRI requirements: PSL0102WBEC1 provides higher CRI (90 vs. 80), beneficial for color-critical applications, while PSL0102WBEB1 offers higher luminous efficiency (95 vs. 75 lm/W).

Critical Design Changes Required: Substitution demands circuit redesign due to forward voltage increase (2.72V to 3.3V), current reduction (700mA to 120mA maximum), and height reduction (3.15mm to 1.00mm). These electrical and mechanical differences necessitate recalculation of current-limiting resistors, power supply compatibility verification, and PCB layout adjustment for component height clearance.

Compliance Status: Both substitute parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements equivalent to the primary part.

Frequently Asked Questions (FAQ)

Q: Can PSL0102WBEB1 or PSL0102WBEC1 be used as direct drop-in replacements for XMLBWT-00-0000-000PS50Z7?

A: No. While both substitute parts share the identical 2020 (5050 metric) package footprint and surface mount configuration, they are not direct drop-in replacements. The forward voltage differs (3.3V vs. 2.72V), maximum current rating is significantly lower (200mA vs. 3A), and component height is reduced (1.00mm vs. 3.15mm). These differences require circuit redesign, including current-limiting resistor recalculation and power supply compatibility verification.

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

A: Both parts are identical in electrical and mechanical specifications except for luminous flux and color rendering index. PSL0102WBEB1 delivers 38 lm at 120mA with 80 CRI and 95 lm/W efficiency. PSL0102WBEC1 delivers 30 lm at 120mA with 90 CRI and 75 lm/W efficiency. Selection depends on whether luminous efficiency or color rendering accuracy is prioritized for the application.

Q: Why do the substitute parts have obsolete product status?

A: Obsolete status indicates that ROHM Semiconductor has discontinued active manufacturing and support for the PSL0102 series. This status limits future availability and may affect long-term supply chain reliability. The primary part XMLBWT-00-0000-000PS50Z7 maintains active status, making it the preferred choice for new designs requiring extended product lifecycle support.

Q: Can the color temperature difference (3000K warm white vs. 5000K cool white) be accommodated in the application?

A: Color temperature substitution is application-dependent. Warm white (3000K) produces a more amber-toned light suitable for residential and accent lighting. Cool white (5000K) produces a more neutral, daylight-like appearance suitable for task lighting and commercial applications. Substitution is only viable if the application requirements explicitly permit this color temperature shift.

Q: Are there thermal management differences between the primary part and substitutes?

A: Yes. The primary part specifies thermal resistance of 2.5°C/W. The substitute parts do not provide thermal resistance specifications. Additionally, the substitute parts operate at significantly lower current (120mA vs. 700mA), resulting in lower absolute heat generation. However, the absence of thermal resistance data for substitutes requires independent thermal analysis if the application involves high-temperature environments or thermal management is critical.

Q: What packaging format differences exist?

A: The primary part is supplied in Tape & Reel (TR) format, suitable for high-volume automated assembly. Both substitute parts are supplied in Cut Tape (CT) format, which is typically used for lower-volume or manual assembly applications. This difference may affect procurement logistics and assembly process compatibility.
