Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: EAST16084BA0

The EAST16084BA0 is the qualified substitute for the obsolete EAST16083BA0 based on the following engineering criteria:

Compliance & Certification Alignment: Both components maintain ROHS3 compliance and identical Moisture Sensitivity Level (MSL) ratings of 3 (168 Hours), ensuring equivalent environmental handling and regulatory requirements.

Electrical Compatibility: The forward voltage differential of 0.15V (2.95V vs. 2.8V) falls within acceptable tolerance for LED indication circuits. Both components operate at identical 5mA test current specifications, ensuring circuit-level compatibility without redesign.

Optical & Mechanical Equivalence: Identical package geometry (0603/1608 Metric), mounting type (Surface Mount), lens configuration (Rectangle with Flat Top, Clear), and viewing angle (120°) confirm direct mechanical interchangeability on PCB layouts.

Availability Advantage: The EAST16084BA0 carries active product status with 15,447 units in stock, compared to the obsolete EAST16083BA0 with limited remaining inventory of 1,024 units. This substitution addresses long-term supply chain continuity.

Packaging Consideration: The EAST16084BA0 is supplied in Tape & Reel (TR) format, standard for production environments, whereas the main part packaging is not specified. This represents an operational improvement for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the EAST16084BA0 be used as a direct replacement for the EAST16083BA0 in existing designs?

A: Yes. Both components share identical package specifications (0603/1608 Metric), mounting type (Surface Mount), and optical characteristics (120° viewing angle, clear rectangular lens). The forward voltage difference of 0.15V is within acceptable tolerance for LED indication applications and does not require circuit modification.

Q: What is the significance of the forward voltage difference between these parts?

A: The EAST16083BA0 operates at 2.95V typical forward voltage, while the EAST16084BA0 operates at 2.8V. This 0.15V variation is typical within LED component families and does not affect circuit functionality for standard indication applications. Both parts are tested at 5mA, ensuring consistent brightness performance.

Q: Are there any mechanical compatibility concerns with the height difference?

A: The EAST16083BA0 has a maximum height of 0.40mm, while the EAST16084BA0 has a maximum height of 0.50mm. This 0.10mm difference remains within 0603 package specifications and does not affect PCB assembly, solder reflow profiles, or component placement on standard surface mount equipment.

Q: Why is the EAST16083BA0 classified as obsolete?

A: The EAST16083BA0 is listed as obsolete, indicating discontinued manufacturing. The EAST16084BA0, with active product status and significantly higher inventory availability (15,447 units), is the recommended substitute for new designs and ongoing production requirements.

Q: Do both components meet the same environmental and compliance standards?

A: Yes. Both the EAST16083BA0 and EAST16084BA0 are ROHS3 compliant and carry identical Moisture Sensitivity Level (MSL) ratings of 3 (168 Hours). They meet equivalent environmental handling, storage, and regulatory requirements.

Q: What is the difference between wavelength peak and wavelength dominant specifications?

A: The wavelength peak (468nm) represents the spectral output at maximum intensity. The wavelength dominant (470nm, specified only for the EAST16084BA0) indicates the perceived color wavelength. Both specifications confirm blue LED operation within the same optical spectrum.

Q: Is the Tape & Reel packaging of the EAST16084BA0 compatible with automated assembly?

A: Yes. Tape & Reel (TR) packaging is the standard format for automated surface mount assembly processes. This represents an operational advantage over unspecified packaging, enabling efficient high-volume production workflows.
