Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DB1113F-TR are identified based on the following critical parameters that determine functional compatibility:

Core Compatibility Criteria:

• Wavelength - Dominant: 470nm (blue spectrum)
• Mounting Type: Surface Mount, Right Angle
• Package / Case: 2-SMD, No Lead configuration
• Lens Size: 1.70mm x 0.60mm
• Size / Dimension: 2.10mm L x 1.00mm W
• Voltage - Forward (Vf): 3.2V to 3.3V range
• Viewing Angle: 120° to 130°

Acceptable Parameter Variations:

• Millicandela Rating: Higher brightness ratings are acceptable for indication applications
• Lens Transparency: Clear lens substitutes diffused lens in equivalent optical performance
• Current - Test: Variations within standard LED operating ranges
• Height (Max): Tolerance within 0.60mm to 0.70mm
• Product Status: Active status preferred for supply chain continuity

Two substitute parts meet these criteria and maintain functional equivalence to the DB1113F-TR.

Parameter Comparison

Engineering Selection Recommendations

LTST-S220TBKT (Lite-On Inc.) - Primary Substitute

The LTST-S220TBKT is the preferred substitute for the DB1113F-TR. This part maintains identical forward voltage (3.3V) and viewing angle (130°), ensuring direct electrical and optical compatibility. The LTST-S220TBKT is active product status with ROHS3 compliance and improved moisture sensitivity rating (MSL 3 versus MSL 4). The exposed pad configuration in the 2-SMD no-lead package provides enhanced thermal performance. Height reduction from 0.70mm to 0.60mm is within acceptable mechanical tolerance for right-angle SMD applications. Current inventory of 2300 units supports production continuity.

APA2106PBC/A (Kingbright) - Secondary Substitute

The APA2106PBC/A provides functional equivalence with 3.2V forward voltage within the acceptable range for 3.3V applications. Active product status and ROHS3 compliance meet regulatory requirements. The 60mcd brightness rating exceeds the DB1113F-TR specification, suitable for applications where increased luminous intensity is acceptable. Viewing angle of 120° represents a 10° reduction from the original specification. Clear lens transparency differs from the diffused lens of the DB1113F-TR. Inventory of 924 units is available. This substitute is applicable where brightness enhancement and clear lens characteristics are compatible with circuit design requirements.

Compliance and Regulatory Alignment

Both substitute parts maintain REACH unaffected status and EAR99 ECCN classification, matching the regulatory profile of the DB1113F-TR. ROHS3 compliance of both substitutes exceeds the original part specification. Tariff classification (HTSUS 8541.41.0000) remains consistent across all three parts.

Frequently Asked Questions (FAQ)

Q: Can the LTST-S220TBKT directly replace the DB1113F-TR without circuit modification?

A: Yes. The LTST-S220TBKT maintains identical forward voltage (3.3V) and viewing angle (130°), enabling direct substitution in existing circuit designs. The 0.10mm height reduction is within acceptable mechanical tolerance for surface mount right-angle LED applications.

Q: What is the impact of lens transparency differences between the DB1113F-TR and substitute parts?

A: The DB1113F-TR features a diffused white lens, while both LTST-S220TBKT and APA2106PBC/A use colorless clear lenses. Clear lenses provide higher light transmission and more directional output. Diffused lenses scatter light more broadly. Circuit design must account for these optical characteristics when selecting between diffused and clear lens options.

Q: Are the brightness differences between DB1113F-TR (14mcd) and substitutes significant?

A: The LTST-S220TBKT (104mcd) and APA2106PBC/A (60mcd) provide higher brightness than the original 14mcd specification. For indication applications, higher brightness is generally acceptable and may improve visibility. Circuit current limiting resistors should be verified to ensure operation within specified current ranges (10mA for DB1113F-TR, 20mA for substitutes).

Q: What is the significance of the exposed pad in the LTST-S220TBKT package?

A: The exposed pad in the 2-SMD no-lead exposed pad configuration provides improved thermal dissipation compared to standard 2-SMD no-lead packages. This enhances thermal performance during high-current or extended operation, contributing to improved reliability and lifespan.

Q: How do moisture sensitivity levels affect component handling and storage?

A: The DB1113F-TR has MSL 4 (72 hours), while both substitutes have MSL 3 (168 hours). MSL 3 provides extended moisture absorption tolerance, allowing longer shelf life and more flexible handling procedures. Lower MSL ratings reduce risk of moisture-induced defects during reflow soldering.

Q: Are there any viewing angle considerations for circuit layout?

A: The DB1113F-TR and LTST-S220TBKT both specify 130° viewing angle, providing wide-angle indication capability. The APA2106PBC/A specifies 120° viewing angle, a 10° reduction. For applications requiring maximum light distribution, the 130° angle specification is preferred. For focused indication in specific directions, the 120° angle may be acceptable.

Q: What is the difference between the DB1113F-TR and LTST-S220TBKT in terms of product lifecycle?

A: The DB1113F-TR is obsolete, indicating discontinued manufacturing and limited future availability. The LTST-S220TBKT is active product status, ensuring ongoing manufacturing, supply chain support, and long-term availability. Active status is recommended for new designs and production planning.
