PSL0102WBEC1 Equivalent & Substitute Parts

Part Overview

The PSL0102WBEC1 is a surface-mount LED from ROHM Semiconductor, classified as a cool white (5000K) lighting component in the 2020 (5050 metric) package format. This part is designated as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity. The PSL0102 series operates at 3.3V with a maximum current rating of 200mA and delivers 30lm at the test current of 120mA, achieving 75 lm/W efficiency with a 90 CRI rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PSL0102WBEC1 is determined by the following critical parameters:

• Package Format: All substitutes must use the 2020 (5050 metric) surface-mount package with identical footprint dimensions (5.00mm x 5.00mm)
• Mounting Type: Surface mount compatibility required
• Color Temperature Range: Cool to neutral white spectrum (4500K–5000K) acceptable for functional equivalence
• Forward Voltage (Vf): Operating voltage must be compatible with the application circuit; the PSL0102WBEC1 operates at 3.3V
• Current Rating: Maximum current capacity must support the intended application load
• Luminous Flux: Minimum lumen output should meet or exceed application requirements
• Compliance: RoHS and REACH compliance status must be verified for regulatory requirements

Two substitute parts are identified based on package compatibility and electrical operating characteristics:

1. XMLBWT-00-0000-000LT60E4 (CreeLED, Inc.) – Neutral white (4500K), closest color temperature match to cool white specification
2. XMLBEZ-00-0000-0D00U630F (CreeLED, Inc.) – Warm white (3000K), alternative for applications tolerating broader color temperature range

Parameter Comparison

Engineering Selection Recommendations

XMLBWT-00-0000-000LT60E4 is the primary substitute candidate based on color temperature alignment (4500K neutral white vs. 5000K cool white). Both parts maintain RoHS and REACH compliance. However, circuit redesign is required due to significant differences in forward voltage (2.72V vs. 3.3V) and test current (700mA vs. 120mA). The substitute delivers substantially higher luminous flux (290lm vs. 30lm) and superior efficiency (143 lm/W vs. 75 lm/W). Physical height differs (3.15mm vs. 1.00mm seated), requiring PCB layout verification. CRI is lower (75 vs. 90), which may impact color-critical applications.

XMLBEZ-00-0000-0D00U630F is a secondary alternative for applications where warm white (3000K) color temperature is acceptable. This part operates at 12V, requiring significant circuit modification. Maximum current capacity (1A) and luminous flux (390lm) exceed the original specification. Height and CRI considerations apply similarly. Active product status ensures long-term availability for both CreeLED substitutes.

Frequently Asked Questions (FAQ)

Q: Can XMLBWT-00-0000-000LT60E4 be used as a direct drop-in replacement for PSL0102WBEC1?

A: No. While both parts share the 2020 (5050 metric) package footprint, the forward voltage (2.72V vs. 3.3V), test current (700mA vs. 120mA), and seated height (3.15mm vs. 1.00mm) differ significantly. Circuit redesign and PCB layout verification are required.

Q: What is the primary difference between the two substitute parts?

A: XMLBWT-00-0000-000LT60E4 operates at 2.72V with 700mA test current and delivers 290lm at neutral white (4500K). XMLBEZ-00-0000-0D00U630F operates at 12V with 350mA test current and delivers 390lm at warm white (3000K). Selection depends on voltage availability, current capacity, and acceptable color temperature range.

Q: Are both substitute parts RoHS and REACH compliant?

A: Yes. Both XMLBWT-00-0000-000LT60E4 and XMLBEZ-00-0000-0D00U630F are RoHS Compliant and REACH Unaffected, matching the compliance profile of the PSL0102WBEC1.

Q: How does the color rendering index (CRI) of the substitutes compare to the original part?

A: The PSL0102WBEC1 has a CRI of 90. XMLBWT-00-0000-000LT60E4 has a CRI of 75 (Typ), and XMLBEZ-00-0000-0D00U630F has a CRI of 82 (Typ). Applications requiring high color fidelity should account for this reduction.

Q: What is the impact of the height difference on PCB design?

A: The PSL0102WBEC1 has a maximum seated height of 0.039" (1.00mm), while both substitutes have a maximum seated height of 0.124" (3.15mm). This 3.15mm height increase may affect clearance in space-constrained designs and requires PCB layout review.

Q: Can the PSL0102WBEC1 be sourced despite its obsolete status?

A: The PSL0102WBEC1 is listed as obsolete. Current inventory of 1,627 pieces is available through existing stock channels, but long-term procurement cannot be guaranteed. Migration to active substitute parts is recommended for new designs and ongoing production.
