PSL0101WBFD1 Equivalent & Substitute Parts

Part Overview

The PSL0101WBFD1 is a warm white LED (3000K) manufactured by Rohm Semiconductor, designed for surface mount applications in the 2020 (5050 Metric) package. This component operates at 3.3V with a test current of 350mA and delivers 90 lumens at 25°C. The product is currently obsolete, making equivalent substitutes necessary for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the PSL0101WBFD1 is determined by the following critical parameters:

• Package / Case: 2020 (5050 Metric) — mechanical compatibility with PCB footprints
• Color & CCT: White, Warm 3000K — color temperature specification for lighting applications
• Mounting Type: Surface Mount — assembly process compatibility
• Voltage & Current Ratings: Forward voltage and test current determine circuit compatibility
• Flux Output: Lumens at specified test current ensure functional equivalence
• Compliance: RoHS and REACH status for regulatory requirements

Two substitute parts meet these criteria with varying trade-offs in electrical characteristics and performance metrics.

Parameter Comparison

Engineering Selection Recommendations

XMLBEZ-00-0000-0D00U630F (Primary Substitute)

This CreeLED Easywhite® XM-L2 LED matches the PSL0101WBFD1 in color temperature (3000K warm white) and test current (350mA). The part is active in production status, ensuring long-term availability. RoHS compliance is maintained. The primary design consideration is the forward voltage difference: 12V versus 3.3V requires circuit redesign for voltage regulation. The increased height (3.15mm vs. 1.00mm) must be evaluated for PCB clearance constraints. CRI improves to 82 from 73, and efficiency increases to 93 lm/W.

XMLBWT-00-0000-000LT60E4 (Secondary Substitute)

This CreeLED XLamp® XM-L2 LED offers the closest forward voltage match (2.72V vs. 3.3V) and is active in production. However, the color temperature is 4500K (neutral white) rather than 3000K (warm white), making this suitable only for applications where color temperature shift is acceptable. The test current is doubled to 700mA, requiring circuit modifications. Efficiency is significantly higher at 143 lm/W. RoHS compliance is maintained. Height is 3.15mm, matching the primary substitute.

Both substitutes maintain the 2020 (5050 Metric) package footprint and surface mount compatibility. Selection depends on circuit voltage capability and color temperature tolerance.

Frequently Asked Questions (FAQ)

Q: Can XMLBEZ-00-0000-0D00U630F be used as a direct drop-in replacement?

A: No. While the package footprint and test current match, the forward voltage increases from 3.3V to 12V. Circuit redesign is required. Additionally, the component height increases from 1.00mm to 3.15mm, which may affect PCB clearance.

Q: Why is XMLBWT-00-0000-000LT60E4 listed as a substitute if the color temperature differs?

A: This part is included because it shares the same package, mounting type, and mechanical compatibility. The 4500K neutral white color temperature represents a functional shift rather than a direct equivalent. Use this substitute only if the application tolerates color temperature change from 3000K to 4500K.

Q: What is the impact of the height difference between the main part and substitutes?

A: The PSL0101WBFD1 is 1.00mm tall, while both substitutes are 3.15mm tall. This 2.15mm increase may affect clearance with adjacent components, conformal coating processes, or enclosure design. PCB layout must be evaluated before substitution.

Q: Are both substitutes RoHS compliant?

A: Yes. Both XMLBEZ-00-0000-0D00U630F and XMLBWT-00-0000-000LT60E4 are RoHS compliant and REACH unaffected, matching the compliance profile of the PSL0101WBFD1.

Q: What is the significance of the MacAdam Ellipse specification on XMLBEZ-00-0000-0D00U630F?

A: The 4-Step MacAdam Ellipse indicates color consistency tolerance. This specification defines the acceptable variation in color coordinates across the production batch, ensuring consistent warm white appearance across multiple units.

Q: How do the efficiency ratings compare?

A: The PSL0101WBFD1 operates at 78 lm/W. XMLBEZ-00-0000-0D00U630F improves to 93 lm/W, and XMLBWT-00-0000-000LT60E4 reaches 143 lm/W. Higher efficiency reduces power consumption and heat generation in the application circuit.
