Equivalent & Substitute Parts: 69-23UTD/TR8

Part Overview

The 69-23UTD/TR8 is a white LED indication component manufactured by Everlight Electronics Co Ltd, configured as a 6-SMD, No Lead surface mount device. This part operates at 3.3V forward voltage with a 20mA test current and delivers 6000mcd brightness with a 60° viewing angle. The component features a square lens with flat top and diffused transparency, housed in a 3.30mm × 3.30mm × 1.60mm package.

The 69-23UTD/TR8 is classified as obsolete. Locating equivalent or substitute components is necessary to support ongoing production requirements, maintenance operations, and design revisions where this part is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 69-23UTD/TR8 is evaluated based on the following critical parameters:

Electrical Compatibility:

• Forward voltage (Vf) within acceptable tolerance range
• Test current matching or compatible with circuit design
• Millicandela rating sufficient for intended indication function

Mechanical Compatibility:

• Surface mount mounting type
• Package footprint compatibility with PCB layout
• Height clearance within design constraints

Optical Compatibility:

• White color emission
• Lens transparency characteristics (diffused vs. clear)
• Viewing angle suitable for application requirements

Environmental & Compliance:

• Moisture sensitivity level appropriate for storage and assembly conditions
• RoHS compliance status for regulatory requirements

The EAPL3528WA0 is identified as a substitute part based on shared electrical characteristics (white color, similar forward voltage of 3.25V, matching 20mA test current), surface mount configuration, and active product status. Differences in package type (4-SMD J-Lead vs. 6-SMD No Lead), lens style, brightness rating, and viewing angle are documented for engineering evaluation.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The 69-23UTD/TR8 is classified as obsolete, making the EAPL3528WA0 a viable alternative due to its active product status. Active status ensures continued availability, manufacturing support, and compliance with current regulatory standards.

Compliance & Certification: The EAPL3528WA0 carries ROHS3 compliance certification, meeting current environmental and hazardous substance restrictions. This certification supports long-term supply chain viability and regulatory alignment for new designs or production revisions.

Electrical Compatibility: Forward voltage differential of 0.05V (3.3V vs. 3.25V) is within typical circuit tolerance ranges for LED indication applications. Both parts operate at identical 20mA test current, ensuring compatible drive circuit requirements.

Optical Performance: The EAPL3528WA0 delivers 5400mcd versus the original 6000mcd, representing a 10% reduction in brightness. The substitute provides a wider 120° viewing angle compared to the original 60° specification. These optical differences must be evaluated against specific application requirements for indication visibility and directional viewing constraints.

Mechanical Considerations: Package footprint differences (6-SMD No Lead vs. 4-SMD J-Lead) and height variation (1.60mm vs. 2.10mm) require PCB layout verification. The substitute's smaller footprint may offer design flexibility, while increased height requires clearance validation.

Moisture Sensitivity: The EAPL3528WA0 carries MSL 3 (168 Hours) versus MSL 2 (1 Year) for the original part. This represents more stringent moisture handling requirements during storage and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the EAPL3528WA0 directly replace the 69-23UTD/TR8 without PCB modifications?

A: Direct replacement without PCB modifications is not possible. The EAPL3528WA0 uses a 4-SMD J-Lead package versus the original 6-SMD No Lead configuration. PCB footprint redesign is required. Additionally, the increased height (2.10mm vs. 1.60mm) must be verified for clearance compatibility.

Q: What is the impact of the 600mcd brightness difference between these parts?

A: The EAPL3528WA0 provides 5400mcd compared to the original 6000mcd, a 10% reduction. For indication applications where brightness is not critical to functionality, this difference is typically acceptable. Applications requiring specific minimum brightness levels must evaluate whether 5400mcd meets performance criteria.

Q: How does the 120° viewing angle of the EAPL3528WA0 compare to the original 60° specification?

A: The wider 120° viewing angle provides greater visibility from off-axis positions. For applications where the LED indication must be visible from multiple angles, this is advantageous. For applications requiring directional indication with limited viewing angle, the wider angle may not align with design intent.

Q: What are the implications of the MSL 3 moisture sensitivity level?

A: MSL 3 (168 Hours) requires more careful moisture control during storage and assembly compared to MSL 2 (1 Year). Components must be stored in controlled humidity environments and used within specified timeframes after packaging. Assembly processes must follow stricter bake-out procedures if moisture absorption occurs.

Q: Is the EAPL3528WA0 suitable for new design implementations?

A: Yes. The EAPL3528WA0 is classified as active product status with ROHS3 compliance, making it appropriate for new designs. The electrical characteristics (3.25V forward voltage, 20mA test current) are compatible with standard LED drive circuits. Mechanical and optical parameters must be validated against specific application requirements.

Q: Are there any supply chain advantages to using the EAPL3528WA0?

A: The EAPL3528WA0 is an active product with documented inventory availability (1122 Pcs), compared to the obsolete 69-23UTD/TR8. Active product status ensures continued manufacturing support, predictable lead times, and compliance with evolving regulatory standards.
