Key Parameters

Substitute Part Grouping Explanation

Substitution of the AA1102W-TR is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Color specification: Orange
• Wavelength range: Dominant wavelength within orange spectrum (600-610nm acceptable)
• Forward voltage: 2.1V to 2.2V range
• Mounting type: Surface Mount
• Package footprint: 3.00mm L x 1.50mm W (compatible with 1206/3216 Metric land pattern)
• Height constraint: Maximum 1.90mm to ensure PCB assembly compatibility
• Lens transparency: Clear
• Test current: 20mA operation

Functional Parameters:

• Millicandela rating and viewing angle may vary within application tolerance
• Moisture sensitivity level may differ if component meets or exceeds MSL 4 requirements

The substitute part APL3015SECK-F01 from Kingbright meets the mandatory compatibility criteria for footprint, voltage, wavelength, and mounting type, enabling direct substitution in the PCB assembly process.

Engineering Selection Recommendations

Product Status Consideration: The AA1102W-TR is classified as obsolete, making continued procurement from original sources unavailable. The APL3015SECK-F01 maintains active product status with established supply chain availability (83,820 pcs in stock).

Compliance and Certifications: Both parts carry identical REACH Status (REACH Unaffected) and ECCN classification (EAR99). The APL3015SECK-F01 provides additional RoHS3 compliance certification, meeting modern regulatory requirements.

Electrical Compatibility: Forward voltage differential of 0.1V (2.2V vs 2.1V) falls within standard circuit design tolerance for LED indication applications. Both components operate at identical 20mA test current.

Optical Characteristics: Wavelength specifications place both components within the orange spectrum range. The APL3015SECK-F01 provides significantly higher luminous intensity (350mcd vs 9mcd), suitable for applications requiring enhanced visibility. Viewing angle is narrower (70° vs 77°/87°), which may affect peripheral visibility in specific application contexts.

Physical Compatibility: Footprint dimensions are identical (3.00mm L x 1.50mm W), ensuring PCB land pattern compatibility. The APL3015SECK-F01 exhibits lower maximum height (1.40mm vs 1.90mm), providing additional clearance margin in space-constrained assemblies.

Moisture Sensitivity: The APL3015SECK-F01 offers improved moisture sensitivity level (MSL 3 vs MSL 4), extending safe storage duration from 72 hours to 168 hours.

Frequently Asked Questions (FAQ)

Q: Can the APL3015SECK-F01 be used as a direct replacement for the AA1102W-TR without PCB modifications?

A: Yes. Both components share identical footprint dimensions (3.00mm L x 1.50mm W) and mounting type (Surface Mount). No PCB land pattern changes are required. The APL3015SECK-F01 exhibits lower profile height (1.40mm), providing additional assembly clearance.

Q: What is the significance of the 0.1V forward voltage difference between these components?

A: The forward voltage differential (2.2V vs 2.1V) is within standard tolerance for LED indication circuits. Series resistor values may require minor adjustment to maintain identical current limiting behavior, but this difference does not prevent substitution in typical applications.

Q: Why does the APL3015SECK-F01 have significantly higher millicandela rating (350mcd vs 9mcd)?

A: The brightness difference reflects different LED chip designs and optical configurations. The higher rating indicates enhanced luminous intensity output. Application requirements determine whether this increased brightness is acceptable or requires circuit-level adjustment through resistor modification.

Q: Are there viewing angle implications when substituting to the APL3015SECK-F01?

A: The APL3015SECK-F01 provides a narrower viewing angle (70° vs 77°/87°). In applications where peripheral visibility is critical, this narrower angle may affect performance. Applications requiring wide-angle indication should evaluate this parameter against specific requirements.

Q: What packaging format differences exist between these components?

A: The AA1102W-TR uses 1206 (3216 Metric) package designation, while the APL3015SECK-F01 is specified as 2-SMD, No Lead (Chip LED). Despite different nomenclature, both components share identical footprint dimensions and are compatible with standard 1206 land patterns.

Q: Does the improved MSL rating of the APL3015SECK-F01 affect handling procedures?

A: The APL3015SECK-F01 provides MSL 3 (168 hours) versus MSL 4 (72 hours). This improvement extends the safe storage window before moisture absorption becomes problematic. Standard moisture control procedures remain applicable; the higher rating provides additional process flexibility.

Q: Is the APL3015SECK-F01 suitable for applications requiring RoHS compliance?

A: Yes. The APL3015SECK-F01 carries ROHS3 Compliant certification. The AA1102W-TR RoHS status is not specified in available documentation. For applications with explicit RoHS requirements, the APL3015SECK-F01 provides documented compliance.
