Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AA1101W-TR are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Color: Orange
• Lens Color: Colorless
• Lens Transparency: Clear
• Mounting Type: Surface Mount
• Package footprint compatibility: 3.00mm L x 1.50mm W
• Wavelength range: 600nm to 610nm (dominant and peak wavelengths)
• Voltage - Forward (Vf): 1.9V to 2.2V at 20mA test current
• Viewing Angle: Minimum 70° (wide angle indication)

Identified Substitute Parts:

1. VFA1101W-5AY3B2-TR (Stanley Electric Co) - Active status, same manufacturer series variant
2. APL3015SECK-F01 (Kingbright) - Active status, alternative manufacturer

Both substitutes maintain orange color, clear colorless lens, surface mount configuration, and compatible wavelength specifications within the acceptable range for orange LED indication applications.

Parameter Comparison

Engineering Selection Recommendations

VFA1101W-5AY3B2-TR Selection Criteria:

The VFA1101W-5AY3B2-TR is the primary substitute for AA1101W-TR applications. Both components share the same manufacturer (Stanley Electric Co), identical package dimensions (3.00mm L x 1.50mm W), and compatible wavelength specifications (605nm dominant vs. 606nm). The VFA1101W-5AY3B2-TR operates at 1.9V forward voltage compared to 2.2V, with increased brightness (12.4mcd vs. 5.6mcd) and maintains wide viewing angle (140° vs. 145°-149°). Product status is Active with ROHS3 compliance and identical MSL rating. This part is suitable for direct substitution in existing PCB layouts without modification.

APL3015SECK-F01 Selection Criteria:

The APL3015SECK-F01 from Kingbright serves as an alternative substitute when VFA1101W-5AY3B2-TR is unavailable. This component maintains orange color, clear colorless lens, and compatible wavelength (601nm dominant). Forward voltage is 2.1V, closely matching the original 2.2V specification. Brightness is significantly higher (350mcd vs. 5.6mcd). Critical differences include package type (2-SMD, No Lead vs. 1206), narrower viewing angle (70° vs. 145°-149°), and reduced height (1.40mm vs. 1.90mm). The APL3015SECK-F01 requires PCB layout verification due to different package configuration. Product status is Active with ROHS3 compliance and improved MSL rating (3 vs. 4).

Compliance Considerations:

Both substitute parts maintain REACH Unaffected status and ECCN EAR99 classification consistent with the original AA1101W-TR. The VFA1101W-5AY3B2-TR and APL3015SECK-F01 are both ROHS3 compliant, supporting regulatory requirements for new designs and production continuity.

Frequently Asked Questions (FAQ)

Q: Can VFA1101W-5AY3B2-TR be used as a direct replacement for AA1101W-TR without PCB modification?

A: Yes. The VFA1101W-5AY3B2-TR maintains identical footprint dimensions (3.00mm L x 1.50mm W) and package type (1206 / 3016 Metric). No PCB layout changes are required. The lower forward voltage (1.9V vs. 2.2V) may require circuit verification to confirm current-limiting resistor values remain appropriate for the application.

Q: What are the key differences between VFA1101W-5AY3B2-TR and APL3015SECK-F01?

A: The primary differences are: (1) Package type - VFA1101W-5AY3B2-TR uses 1206 (3016 Metric) while APL3015SECK-F01 uses 2-SMD No Lead; (2) Brightness - APL3015SECK-F01 is significantly brighter (350mcd vs. 12.4mcd); (3) Viewing angle - VFA1101W-5AY3B2-TR has wider viewing angle (140° vs. 70°); (4) Height - APL3015SECK-F01 is lower profile (1.40mm vs. 1.50mm). The VFA1101W-5AY3B2-TR is the preferred substitute for direct replacement applications.

Q: Does APL3015SECK-F01 require PCB redesign?

A: Yes. The APL3015SECK-F01 uses a different package type (2-SMD, No Lead vs. 1206). PCB footprint verification and potential layout modification are necessary before implementation. The narrower viewing angle (70°) should also be evaluated for the specific indication application.

Q: Are all three parts compliant with current regulatory standards?

A: The VFA1101W-5AY3B2-TR and APL3015SECK-F01 are both ROHS3 compliant and REACH Unaffected. The original AA1101W-TR is REACH Unaffected but RoHS status is not specified. Both substitutes support modern regulatory requirements for new production.

Q: What is the impact of forward voltage differences on circuit design?

A: The AA1101W-TR operates at 2.2V, VFA1101W-5AY3B2-TR at 1.9V, and APL3015SECK-F01 at 2.1V. These differences affect current-limiting resistor calculations. For a given supply voltage and target 20mA test current, resistor values must be recalculated. Verify that existing resistor values maintain appropriate current levels with the substitute part's forward voltage specification.

Q: Which substitute part has better long-term availability?

A: Both VFA1101W-5AY3B2-TR and APL3015SECK-F01 are classified as Active products with substantial inventory levels (4691 Pcs and 83820 Pcs respectively). The VFA1101W-5AY3B2-TR is recommended as the primary choice due to identical package compatibility and same-manufacturer sourcing from Stanley Electric Co.
