Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the EAST3215RA4-AM are identified based on strict parameter alignment within the red LED indication component category. The substitution logic is governed by the following critical parameters:

Package Compatibility: All substitute parts must use the 1206 (3216 Metric) surface mount package with identical 3.20mm L x 1.50mm W dimensions and maximum 1.10mm height to ensure PCB footprint compatibility without layout redesign.

Optical Specifications: Substitute parts must maintain red color output with dominant wavelength in the range of 626nm to 632nm, ensuring consistent color perception and application suitability. Viewing angle must remain at 130° to preserve optical distribution characteristics.

Electrical Parameters: Forward voltage (Vf) must remain within 2.0V to 2.05V at 20mA test current to ensure circuit compatibility with existing driver designs. Current-test specification remains fixed at 20mA as the reference operating point.

Mechanical Characteristics: Lens style must be Rectangle with Flat Top with 2.00mm x 1.50mm lens size to maintain mechanical fit and optical performance consistency.

Regulatory Compliance: All substitute parts must maintain ROHS3 compliance status to satisfy environmental and regulatory requirements.

Manufacturer Consistency: Substitute parts are sourced from Everlight Electronics Co Ltd to maintain supply chain consistency and quality assurance standards.

The EAST3215RA1 is identified as a parametric equivalent based on these criteria, with minor variations in wavelength-peak specification (632nm vs 639nm) and moisture sensitivity level (MSL 3 vs MSL 2) that do not affect functional substitution capability.

Engineering Selection Recommendations

Primary Selection - EAST3215RA4-AM: Select this part number when standard packaging (cut tape or bulk) is acceptable and MSL 2 moisture sensitivity with extended 1-year shelf life is required. This configuration is suitable for applications with standard inventory management and storage conditions.

Substitute Selection - EAST3215RA1: Select this part number when tape and reel (TR) packaging format is required for automated assembly processes. This substitute provides equivalent optical and electrical performance with the following considerations:

The EAST3215RA1 operates at 2.05V forward voltage compared to 2.0V for the main part, representing a 0.05V increase. This variance remains within acceptable circuit tolerance for standard LED driver designs but should be verified against specific power supply specifications if tight voltage regulation is required.

The EAST3215RA1 delivers 106mcd luminous intensity compared to 98mcd for the main part, representing an 8% brightness increase. This higher intensity is compatible with applications designed for the main part and does not introduce compatibility issues.

The EAST3215RA1 operates under MSL 3 moisture sensitivity with 168-hour shelf life compared to MSL 2 with 1-year shelf life for the main part. This requires stricter moisture control during storage and handling. Select this part only when tape and reel packaging justifies the enhanced moisture management requirements.

Both parts maintain identical package dimensions, mounting type, and ROHS3 compliance status, ensuring direct PCB footprint compatibility and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can EAST3215RA1 be used as a direct replacement for EAST3215RA4-AM in existing designs?

A: Yes, the EAST3215RA1 is a direct functional substitute for the EAST3215RA4-AM. Both parts share identical package dimensions (1206/3216 Metric), mounting type (surface mount), and optical characteristics (130° viewing angle, red color, clear lens). The forward voltage difference of 0.05V (2.05V vs 2.0V) and brightness increase of 8mcd are within acceptable operating ranges for standard LED indication circuits. Verify that your specific circuit design accommodates the 0.05V voltage variance.

Q: What is the difference in packaging between these two parts?

A: The EAST3215RA4-AM is supplied in standard packaging format (cut tape or bulk), while the EAST3215RA1 is supplied in tape and reel (TR) format. Tape and reel packaging is optimized for automated pick-and-place assembly processes and high-volume production. Standard packaging is suitable for manual assembly or lower-volume applications. Select based on your assembly process requirements.

Q: Why does the EAST3215RA1 have a shorter shelf life (MSL 3 vs MSL 2)?

A: The EAST3215RA1 carries MSL 3 moisture sensitivity rating with 168-hour shelf life, compared to MSL 2 with 1-year shelf life for the EAST3215RA4-AM. MSL rating indicates the component's sensitivity to moisture absorption during storage. MSL 3 components require more stringent moisture control and must be used within 168 hours of package opening under standard conditions. This does not affect performance after installation but requires careful inventory management and handling procedures.

Q: Are both parts ROHS3 compliant?

A: Yes, both the EAST3215RA4-AM and EAST3215RA1 are ROHS3 compliant, meeting environmental and regulatory requirements for restricted hazardous substances. Both parts are suitable for applications requiring ROHS compliance.

Q: What is the brightness difference between these parts?

A: The EAST3215RA1 delivers 106mcd luminous intensity compared to 98mcd for the EAST3215RA4-AM, representing an 8% increase in brightness. This higher intensity is compatible with applications designed for the main part and does not introduce compatibility issues. The identical 130° viewing angle ensures consistent optical distribution.

Q: Can I mix these parts in the same production batch?

A: Both parts are functionally equivalent and can be used interchangeably in the same circuit design. However, mixing parts from different packaging formats (standard vs tape and reel) may complicate inventory management and assembly process optimization. Standardize on one part number per production batch to maintain process consistency and traceability.

Q: What is the dominant wavelength difference and does it affect color perception?

A: The EAST3215RA1 has a dominant wavelength of 626nm compared to 632nm for the EAST3215RA4-AM, a difference of 6nm. Both wavelengths fall within the red spectrum and produce visually equivalent red color output for indication applications. This wavelength variance does not affect color perception in standard LED indication applications.
