Package / Case: 2-SMD, No Lead
Lens Transparency: Clear
Lens Style: Rectangle with Domed Top
Size / Dimension: 3.00mm L x 2.00mm W (acceptable tolerance: ±0.20mm)
Height (Max): 1.00mm

Secondary Compatibility Parameters:

Viewing Angle: 130° to 160° (original: 143°, 136°)

Engineering Selection Recommendations

Tier 1 Direct Equivalents (Highest Compatibility):

The following parts satisfy all primary substitution criteria and are classified as direct functional equivalents:

5972222602F (Dialight, Strip packaging): Yellow 589nm, 2.1V, 125mcd, 3.00mm x 2.00mm, Active status
5972222607F (Dialight, Tape & Reel packaging): Yellow 589nm, 2.1V, 125mcd, 3.00mm x 2.00mm, Active status
APA3010YC (Kingbright, Tape & Reel packaging): Yellow 588nm, 2.1V, 7mcd, 3.00mm x 2.00mm, Active status
APECVA3010YC (Kingbright): Yellow 588nm, 2.1V, 7mcd, 3.00mm x 2.00mm, Active status
HSMY-C680 (Broadcom Limited, Tape & Reel packaging): Yellow 589nm, 2.1V, 9.3mcd, 3.00mm x 1.00mm, Active status

Tier 2 Compatible Alternatives (Secondary Considerations):

5988350117F (Dialight, Tape & Reel packaging): Yellow 585nm, 2.0V, 140mcd, 3.20mm x 1.50mm. Acceptable for applications tolerating dimensional variation and lower forward voltage.
HSMY-C110 (Broadcom Limited, Cut Tape & Digi-Reel packaging): Yellow 586nm, 2.1V, 8mcd, diffused lens (not clear). Acceptable only for applications where lens transparency is not critical.
HSML-C680 (Broadcom Limited, Tape & Reel packaging): Orange 604nm, 2.0V, 108.6mcd. Not recommended; color mismatch disqualifies this part for yellow indication applications.

Compliance and Certification:

All substitute parts listed in Tier 1 and Tier 2 carry ROHS3 Compliant or RoHS Compliant certification, meeting environmental regulatory requirements. Moisture Sensitivity Level (MSL) ratings range from 2A to 3, representing improved handling characteristics compared to the original AY1101F-TR (MSL 4). All parts maintain REACH Unaffected status and EAR99 ECCN classification.

Packaging Considerations:

Dialight 5972222607F and Kingbright APA3010YC are supplied in Tape & Reel (TR) format, suitable for automated assembly processes. Dialight 5972222602F is supplied in Strip format. Broadcom HSMY-C680 is supplied in Tape & Reel format. Selection between packaging options depends on production volume and assembly equipment compatibility.

Frequently Asked Questions (FAQ)

Q: Can I use 5972222607F as a direct replacement for AY1101F-TR?

A: Yes. The 5972222607F meets all primary substitution criteria: yellow color, 589nm dominant wavelength (within 590nm specification), 2.1V forward voltage, 20mA test current, 2-SMD No Lead package, surface mount right angle configuration, and 3.00mm x 2.00mm dimensions. The part is Active status with ROHS3 compliance.

Q: What is the difference between APA3010YC and APECVA3010YC?

A: Both parts are functionally identical in electrical and optical specifications: yellow 588nm, 2.1V, 7mcd, 2-SMD No Lead package, 3.00mm x 2.00mm dimensions. The primary difference is packaging designation. APA3010YC is supplied in Tape & Reel format; APECVA3010YC packaging is unspecified in the provided data. Verify packaging requirements with your procurement specification.

Q: Why does 5988350117F have different dimensions (3.20mm x 1.50mm) compared to the original?

A: The 5988350117F belongs to the Dialight 598 series, which uses a different mechanical envelope than the 597 series. While the part maintains 2-SMD No Lead package classification and surface mount right angle mounting, the dimensional variation requires PCB layout verification before substitution. This part is classified as Tier 2 compatible.

Q: Can I substitute HSMY-C110 for AY1101F-TR?

A: HSMY-C110 is not recommended as a direct substitute. While it matches color (yellow), wavelength (586nm), voltage (2.1V), and mounting type, the lens transparency is diffused rather than clear. This optical property change affects light distribution characteristics. Use HSMY-C110 only if your application does not require clear lens transparency.

Q: What does MSL 2A (4 Weeks) mean compared to MSL 4 (72 Hours)?

A: MSL (Moisture Sensitivity Level) indicates the maximum time a component can be stored in standard conditions (23°C, 50% relative humidity) before requiring baking. MSL 2A allows 4 weeks of storage; MSL 4 allows only 72 hours. Substitute parts with lower MSL ratings (2A, 3) offer extended shelf life and reduced risk of moisture-induced failures during assembly.

Q: Are all substitute parts RoHS compliant?

A: Yes. All Tier 1 and Tier 2 substitute parts carry either RoHS Compliant or ROHS3 Compliant certification. ROHS3 represents the current regulatory standard. The original AY1101F-TR carries RoHS Compliant certification. All parts maintain REACH Unaffected status.

Q: Which substitute offers the closest brightness match to the original 3mcd?

A: APA3010YC and APECVA3010YC both deliver 7mcd, representing the closest brightness match among active substitutes. HSMY-C680 delivers 9.3mcd. If exact 3mcd brightness is required, circuit-level current limiting adjustments may be necessary with higher-brightness substitutes.

Q: Can I use 5972211602F or 5972211607F as substitutes?

A: No. These parts are orange (605nm dominant wavelength), not yellow. Color mismatch disqualifies them for applications requiring yellow indication. These parts are listed in the original part's substitute field but are not suitable for direct replacement.
