XMLBWT-00-0000-000HT40F7 LED XLamp® XM-L2 Warm White Equivalent & Substitute Parts

Part Overview

The XMLBWT-00-0000-000HT40F7 is a CreeLED XLamp® XM-L2 warm white LED (3250K) in 2020 (5050 Metric) surface mount package. This part is currently active in production. Substitution becomes necessary when the original part reaches end-of-life status, inventory constraints occur, or alternative sourcing is required while maintaining electrical and mechanical compatibility within specified tolerances.

Substitute Part Grouping Explanation

Substitution of the XMLBWT-00-0000-000HT40F7 is constrained by the following critical parameters:

Mechanical Compatibility:

• Package type must be 2020 (5050 Metric) surface mount
• Physical dimensions must be 5.00mm × 5.00mm
• Height must not exceed 3.15mm seated height to ensure PCB clearance and assembly compatibility

Electrical Compatibility:

• Forward voltage (Vf) must be within the design circuit tolerance (reference: 2.72V nominal)
• Maximum current rating must support the application's current requirements
• Luminous flux and efficacy determine brightness performance at specified operating current

Optical Compatibility:

• Color temperature (CCT) and Color Rendering Index (CRI) define the light quality characteristics
• Viewing angle affects light distribution in the application

Regulatory Compliance:

• RoHS and REACH compliance status must meet application requirements

The substitute parts listed (PSL0102WBEB1 and PSL0102WBEC1) share the same 2020 (5050 Metric) package footprint and surface mount mounting type. However, they differ in color temperature (5000K cool white vs. 3250K warm white), forward voltage (3.3V vs. 2.72V), test current (120mA vs. 700mA), and product status (Obsolete vs. Active). These differences indicate that direct electrical and optical substitution is not feasible without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The XMLBWT-00-0000-000HT40F7 maintains Active status, indicating continued manufacturer support and availability. The listed substitute parts (PSL0102WBEB1 and PSL0102WBEC1) are both marked Obsolete, which restricts their use to legacy system maintenance or applications where long-term supply is not a requirement.

Compliance Alignment: Both substitute parts meet ROHS3 Compliant and REACH Unaffected requirements, matching the regulatory profile of the main part. This ensures compliance continuity in regulated applications.

Electrical and Optical Incompatibility: The substitute parts operate at significantly different electrical parameters (3.3V forward voltage vs. 2.72V, 120mA test current vs. 700mA, 200mA maximum current vs. 3A maximum current) and different color temperature (5000K cool white vs. 3250K warm white). Direct substitution without circuit modification is not feasible. Any application requiring warm white light at 3250K cannot use these cool white (5000K) alternatives without altering the intended light output characteristics.

Mechanical Compatibility: While the substitute parts share the same 2020 (5050 Metric) footprint and 5.00mm × 5.00mm dimensions, their significantly lower seated height (1.00mm vs. 3.15mm) may affect thermal management and mechanical assembly considerations in designs optimized for the taller profile of the XLamp® XM-L2.

For applications requiring warm white LED performance at 3250K with high luminous flux and efficacy, continued use of the XMLBWT-00-0000-000HT40F7 or equivalent warm white alternatives from active product lines is recommended.

Frequently Asked Questions (FAQ)

Q: Can PSL0102WBEB1 or PSL0102WBEC1 be used as direct drop-in replacements for XMLBWT-00-0000-000HT40F7?

A: No. While both substitute parts share the same 2020 (5050 Metric) package footprint, they differ in critical electrical and optical parameters. The substitute parts operate at 3.3V forward voltage (vs. 2.72V), 120mA test current (vs. 700mA), and 5000K color temperature (vs. 3250K warm white). Direct substitution requires circuit redesign to accommodate the different voltage and current characteristics, and will result in cool white light instead of warm white light.

Q: What is the significance of the different seated heights (3.15mm vs. 1.00mm)?

A: The seated height affects PCB clearance, thermal interface design, and mechanical assembly. The XMLBWT-00-0000-000HT40F7 at 3.15mm may be designed into applications with specific thermal management or mechanical constraints. The substitute parts' lower profile (1.00mm) may not provide equivalent thermal coupling or mechanical support in designs optimized for the taller component.

Q: Why are the substitute parts marked Obsolete while the main part is Active?

A: Product status reflects manufacturer support and availability. Obsolete parts are no longer in active production and may have limited or no future availability. The Active status of XMLBWT-00-0000-000HT40F7 indicates continued manufacturer support and supply. For new designs or long-term applications, Active products are preferred.

Q: Can the substitute parts be used if the application circuit is redesigned?

A: Redesign feasibility depends on application requirements. The substitute parts' lower forward voltage (3.3V vs. 2.72V), lower maximum current rating (200mA vs. 3A), and different color temperature (5000K vs. 3250K) require corresponding changes to power supply design, current limiting circuits, and optical design. Applications requiring warm white light at 3250K cannot use cool white alternatives without compromising the intended light output characteristics.

Q: Are there packaging format differences between the main part and substitutes?

A: Yes. The main part is supplied in Tape & Reel (TR) format, while both substitute parts are supplied in Cut Tape (CT) format. This affects procurement, handling, and assembly processes. TR format is typically used for high-volume automated assembly, while CT format is used for lower-volume or manual assembly operations.

Q: Do the substitute parts meet the same compliance requirements?

A: Both substitute parts are ROHS3 Compliant and REACH Unaffected, matching the compliance profile of the main part. This ensures regulatory continuity in applications subject to RoHS and REACH requirements.
