EAST20128RA1 Equivalent & Substitute Parts

Part Overview

The EAST20128RA1 is a red LED indication component manufactured by Everlight Electronics Co Ltd, designed for surface mount applications in the 0805 (2012 Metric) package format. This part operates at a forward voltage of 2.05V with a test current of 20mA, delivering 54 millicandela of luminous intensity at a dominant wavelength of 632nm. The component features a clear, colorless lens with a rectangular flat-top design and a 130° viewing angle, making it suitable for general indication applications requiring discrete red light emission.

The part is currently in active production status with ROHS3 compliance and MSL 2 moisture sensitivity rating. Substitute parts are identified based on strict electrical and mechanical parameter compatibility within the red LED indication category.

Engineering Selection Recommendations

EAST20128RA1 (Everlight Electronics Co Ltd)

This part is the primary reference component and remains in active production status. It carries ROHS3 compliance certification and MSL 2 moisture sensitivity rating with a 1-year shelf life under controlled conditions. Current inventory availability is 1,048 pieces. Selection of this part is appropriate when Everlight Electronics is the specified or preferred manufacturer in design documentation.

LTST-C171KRKT (Lite-On Inc.)

This part is classified as a parametric equivalent and is in active production status with ROHS3 compliance certification. It carries MSL 2A moisture sensitivity rating with a 4-week shelf life under controlled conditions. Current inventory availability is 85,400 pieces. The LTST-C171KRKT is suitable for direct substitution in applications where the EAST20128RA1 is unavailable or where Lite-On Inc. is an approved alternative manufacturer. Both parts meet identical electrical and mechanical specifications within the defined parameter ranges.

Selection between these parts should be based on:

• Manufacturer approval status in design documentation
• Inventory availability requirements
• Supply chain continuity considerations
• Moisture sensitivity handling capabilities during storage and assembly

Frequently Asked Questions (FAQ)

Q: Can the LTST-C171KRKT be used as a direct replacement for the EAST20128RA1?

A: Yes. The LTST-C171KRKT meets all electrical and mechanical parameter specifications for the EAST20128RA1. Both parts are red LEDs in the 0805 (2012 Metric) package with identical forward voltage, test current, luminous intensity, viewing angle, and physical dimensions. Both carry ROHS3 compliance certification.

Q: What are the differences between these two parts?

A: The primary differences are manufacturer identity and moisture sensitivity level. The EAST20128RA1 is manufactured by Everlight Electronics with MSL 2 (1 Year) rating. The LTST-C171KRKT is manufactured by Lite-On Inc. with MSL 2A (4 Weeks) rating. The MSL 2A rating requires more stringent moisture control during storage and assembly compared to MSL 2. Dominant wavelength differs by 1nm (632nm vs. 631nm), which is within normal manufacturing tolerance for red LEDs.

Q: Are there any packaging differences?

A: The EAST20128RA1 is supplied in Tape & Reel (TR) format. The LTST-C171KRKT is supplied in Cut Tape (CT) & Digi-Reel® format. Both formats are standard for surface mount components and are compatible with automated assembly equipment. Selection between packaging formats depends on production volume and assembly line requirements.

Q: What is the significance of the 1nm wavelength difference?

A: The dominant wavelength difference of 1nm (632nm vs. 631nm) falls within normal manufacturing tolerance for red LEDs and does not affect functional equivalence. Both parts have identical peak wavelength (639nm) and will produce visually indistinguishable red light output in indication applications.

Q: How does the moisture sensitivity level affect component handling?

A: MSL 2 (1 Year) allows 12 months of storage under controlled conditions (23°C, 50% relative humidity) before baking is required. MSL 2A (4 Weeks) allows only 4 weeks of storage under the same conditions. If the LTST-C171KRKT is selected, moisture control procedures must be implemented during storage and prior to assembly to prevent moisture absorption that could cause solder joint defects.

Q: Can these parts be mixed in the same production batch?

A: Mixing parts from different manufacturers in the same production batch is not recommended without explicit approval from design engineering and quality assurance. Separate inventory control, traceability documentation, and assembly procedures should be maintained for each manufacturer's part number to ensure proper component tracking and failure analysis capability.
