Substitute Part Grouping Explanation

Substitution of the EAST3215YA3-AM is based on strict electrical and mechanical parameter matching within the yellow LED indication category. The following parameters define substitution eligibility:

Critical Matching Parameters:

• Color: Yellow
• Wavelength - Dominant: 590nm (±1nm tolerance acceptable within yellow spectrum)
• Voltage - Forward (Vf) Typical: 2.05V
• Current - Test: 20mA
• Millicandela Rating: 79mcd
• Viewing Angle: 130°
• Package / Case: 1206 (3216 Metric)
• Mounting Type: Surface Mount
• Lens Style: Rectangle with Flat Top
• Lens Size: 2.00mm x 1.50mm
• Physical Dimensions: 3.20mm L x 1.50mm W, Height 1.10mm max

Non-Critical Variations:

• Packaging format (Tape & Reel vs. standard packaging)
• Moisture Sensitivity Level (MSL) rating
• Inventory availability

The EAST3215YA1 qualifies as a parametric equivalent based on matching all critical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

EAST3215YA3-AM Selection Criteria:

• Standard packaging format required for manual assembly or small-volume applications
• Moisture Sensitivity Level 2 (1 Year) acceptable for storage and handling conditions
• Current inventory of 676 units available for immediate procurement

EAST3215YA1 Selection Criteria:

• Tape & Reel packaging required for automated assembly processes
• Higher inventory availability (2004 units) for large-volume production runs
• Moisture Sensitivity Level 3 (168 Hours) requires controlled storage environment
• Dominant wavelength 589nm falls within acceptable yellow LED specification range

Both parts maintain identical electrical performance, mechanical compatibility, and regulatory compliance (ROHS3). Selection between EAST3215YA3-AM and EAST3215YA1 is determined by packaging requirements, production volume, and storage environment capabilities rather than functional performance.

Frequently Asked Questions (FAQ)

Q: Can EAST3215YA1 directly replace EAST3215YA3-AM in existing designs?

A: Yes. Both components share identical electrical specifications (2.05V forward voltage, 20mA test current, 79mcd brightness), mechanical dimensions (1206 package, 3.20mm x 1.50mm x 1.10mm), and optical properties (590nm/589nm dominant wavelength, 130° viewing angle, clear rectangular lens). The primary difference is packaging format and moisture sensitivity rating.

Q: What is the significance of the 1nm wavelength difference (590nm vs 589nm)?

A: Both wavelengths fall within the yellow LED specification range and produce visually identical color output. The 1nm difference reflects normal manufacturing tolerance within the yellow spectrum (typically 585nm to 595nm). This variation does not affect optical performance or color perception in indication applications.

Q: Why does EAST3215YA1 have a higher Moisture Sensitivity Level (MSL 3 vs MSL 2)?

A: MSL 3 (168 Hours) indicates a shorter shelf life in humid conditions compared to MSL 2 (1 Year). This affects storage and handling procedures but does not impact component performance after assembly. Selection depends on warehouse conditions and production scheduling.

Q: Is Tape & Reel packaging compatible with manual assembly?

A: Tape & Reel packaging (EAST3215YA1) is optimized for automated pick-and-place assembly. Standard packaging (EAST3215YA3-AM) is more suitable for manual assembly or low-volume applications. Both formats contain identical components.

Q: Are both parts ROHS3 compliant?

A: Yes. Both EAST3215YA3-AM and EAST3215YA1 are ROHS3 compliant and suitable for applications requiring lead-free and restricted substance compliance.

Q: Can I use EAST3215YA1 if my design specifies EAST3215YA3-AM?

A: Electrical and optical substitution is valid. Verify that your assembly process accommodates Tape & Reel packaging and that storage conditions meet MSL 3 requirements (168-hour shelf life in controlled humidity). If these conditions are met, EAST3215YA1 is functionally equivalent.
