Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AY1102W-TR are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Color: Yellow
• Wavelength - Dominant: 590nm (±2nm tolerance acceptable for yellow indication applications)
• Voltage - Forward (Vf): 2.0V to 2.2V range
• Current - Test: 20mA
• Mounting Type: Surface Mount
• Lens Transparency: Clear

Secondary Compatibility Considerations:

• Package footprint compatibility (1206/3216 Metric or equivalent land pattern)
• Millicandela rating (brightness may vary within application tolerance)
• Viewing angle (70° minimum acceptable for general indication use)
• Moisture Sensitivity Level (MSL 3 or MSL 4 acceptable)

The two identified substitutes meet these criteria with the following distinctions:

RAY1102W-745-TR (Stanley Electric Co): Maintains identical manufacturer lineage, forward voltage, and test current. Wavelength shifts to 592nm (within yellow spectrum). Brightness increases to 21mcd. Package dimensions remain compatible. Product status is obsolete, matching the main part.

APL3015SYCK-F01 (Kingbright): Represents an active product alternative with identical dominant wavelength (590nm) and forward voltage of 2.0V. Brightness increases significantly to 350mcd. Package format changes to 2-SMD, No Lead (Chip LED) with different physical dimensions. Product status is active, providing long-term availability.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Manufacturer Line):

RAY1102W-745-TR serves as the primary substitute within the Stanley Electric Co product family. This part maintains identical forward voltage (2.2V), test current (20mA), and mounting characteristics. The wavelength shift from 590nm to 592nm remains within the yellow spectrum classification. Brightness increases from 6mcd to 21mcd, which is acceptable for indication applications where the original brightness was not a critical design constraint. Both parts share obsolete status and identical MSL ratings. PCB layout modifications are not required due to compatible footprint dimensions (3.00mm L x 1.50mm W). Height reduction from 1.90mm to 1.50mm may provide clearance benefits in space-constrained designs.

For Long-Term Availability:

APL3015SYCK-F01 from Kingbright provides an active product alternative with guaranteed ongoing availability. This part maintains the exact dominant wavelength (590nm) and achieves superior brightness at 350mcd. Forward voltage is 2.0V, which is within acceptable tolerance for 2.2V-rated circuits. The package format changes from 1206 (3216 Metric) to 2-SMD, No Lead (Chip LED), requiring PCB layout redesign and assembly process adjustment. Physical dimensions remain compatible (3.00mm L x 1.50mm W footprint), but the component height reduces to 1.40mm. MSL rating improves to 3 (168 Hours), providing better moisture tolerance. RoHS3 compliance is confirmed for both substitute parts.

Compliance Considerations:

All three parts share identical REACH status (REACH Unaffected) and ECCN classification (EAR99). The substitute parts provide explicit RoHS3 compliance documentation, whereas the main part does not specify this status. For applications requiring regulatory compliance verification, the substitute parts offer documented compliance records.

Frequently Asked Questions (FAQ)

Q: Can RAY1102W-745-TR be used as a direct drop-in replacement for AY1102W-TR?

A: Yes, RAY1102W-745-TR functions as a direct replacement without PCB modifications. Both parts use identical 1206 (3216 Metric) package footprints with compatible land patterns. Forward voltage (2.2V) and test current (20mA) are identical. The wavelength shift from 590nm to 592nm remains within yellow spectrum specifications. Height reduction from 1.90mm to 1.50mm may improve clearance in constrained designs.

Q: What are the brightness differences between the three parts?

A: AY1102W-TR provides 6mcd brightness. RAY1102W-745-TR increases brightness to 21mcd (3.5x increase). APL3015SYCK-F01 delivers 350mcd (58x increase). Brightness selection depends on application requirements. Higher brightness may require circuit current limiting adjustments if the original design operated at maximum rated current.

Q: Does APL3015SYCK-F01 require PCB redesign?

A: Yes, APL3015SYCK-F01 uses a different package format (2-SMD, No Lead Chip LED) compared to the 1206 (3216 Metric) package of the main part. Although footprint dimensions remain compatible (3.00mm L x 1.50mm W), the component structure differs, requiring PCB layout verification and assembly process adjustment. The lower forward voltage (2.0V versus 2.2V) may require circuit current limiting recalculation.

Q: Are all three parts RoHS compliant?

A: RAY1102W-745-TR and APL3015SYCK-F01 are explicitly ROHS3 compliant. The main part AY1102W-TR does not specify RoHS status in the provided documentation. For applications requiring RoHS compliance verification, the substitute parts provide documented compliance.

Q: What is the moisture sensitivity difference between the parts?

A: AY1102W-TR and RAY1102W-745-TR both have MSL 4 (72 Hours) rating. APL3015SYCK-F01 has improved MSL 3 (168 Hours) rating, providing better moisture tolerance and longer shelf life under controlled humidity conditions.

Q: Can the forward voltage difference (2.0V vs 2.2V) affect circuit operation?

A: The 0.2V difference between APL3015SYCK-F01 (2.0V) and the main part (2.2V) is within typical LED tolerance ranges. Circuit current limiting resistors may require recalculation to maintain the 20mA test current specification. Verify that the power supply voltage provides sufficient headroom for the lower forward voltage to prevent excessive current draw.

Q: What is the viewing angle difference between the parts?

A: AY1102W-TR specifies 70° and 89° viewing angles. RAY1102W-745-TR does not specify viewing angle in the provided data. APL3015SYCK-F01 specifies 70° viewing angle. For applications requiring wide viewing angles, AY1102W-TR provides the broadest specification at 89°. The 70° specification of APL3015SYCK-F01 is acceptable for standard indication applications.

Q: Which substitute part should be selected for new designs?

A: APL3015SYCK-F01 is recommended for new designs due to active product status, ensuring long-term availability and supply chain stability. RoHS3 compliance is explicitly documented. The significantly higher brightness (350mcd) provides design flexibility for various lighting conditions. RAY1102W-745-TR is suitable for legacy system support where existing inventory or design compatibility with Stanley Electric Co components is required.
