Key Parameters

Substitute Part Grouping Explanation

Substitution of the DC1113F-TR requires alignment across the following critical parameters:

Electrical Compatibility: Forward voltage (Vf) of 3.3V is the primary electrical constraint. Test current specifications and wavelength characteristics define the optical performance envelope.

Optical Characteristics: Dominant wavelength at 505nm (blue-green spectrum) and 130° viewing angle establish the visual indication requirements. Brightness rating (34mcd) and lens transparency (diffused) determine visibility characteristics.

Mechanical Compatibility: Surface mount configuration with right-angle mounting orientation and overall dimensions (2.10mm L x 1.00mm W x 0.70mm H max) define the physical footprint constraints.

Package Specification: The 2-SMD, no-lead package format is a critical mechanical constraint for PCB assembly compatibility.

The identified substitute LTST-C170TBKT from Lite-On Inc. maintains electrical compatibility (3.3V Vf) and optical viewing angle (130°) while operating in the blue spectrum (470nm dominant wavelength). However, this substitute introduces variations in package format (0805/2012 Metric), physical dimensions, brightness rating (104mcd), lens transparency (clear vs. diffused), and test current (20mA vs. 10mA).

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The DC1113F-TR is classified as obsolete. The LTST-C170TBKT is active and currently in production, providing long-term availability and supply chain stability.

Compliance and Certification: The LTST-C170TBKT carries ROHS3 compliance certification, whereas the DC1113F-TR compliance status is not specified. Both components are REACH unaffected and classified under ECCN EAR99 and HTSUS 8541.41.0000.

Moisture Sensitivity: The LTST-C170TBKT demonstrates improved moisture handling (MSL 2A, 4 weeks) compared to the DC1113F-TR (MSL 4, 72 hours), indicating superior storage and assembly process tolerance.

Inventory Availability: The LTST-C170TBKT maintains substantial active inventory (105,400 pcs), supporting procurement reliability for production volumes.

Frequently Asked Questions (FAQ)

Q: Can the LTST-C170TBKT directly replace the DC1113F-TR in existing PCB designs?

A: Direct replacement requires PCB layout modification. The LTST-C170TBKT uses 0805 (2012 Metric) package format versus the DC1113F-TR's 2-SMD, no-lead configuration. Physical dimensions differ (2.00mm L x 1.25mm W vs. 2.10mm L x 1.00mm W), and the LTST-C170TBKT lacks right-angle mounting orientation. Footprint redesign is necessary.

Q: What are the optical differences between these components?

A: The DC1113F-TR operates at 505nm (blue-green) with 34mcd brightness and diffused lens. The LTST-C170TBKT operates at 470nm (blue) with 104mcd brightness and clear lens. The 35nm wavelength shift and 3x brightness increase will produce visually distinct indication characteristics. Diffused versus clear lens affects light distribution patterns.

Q: Are the electrical specifications compatible?

A: Both components operate at 3.3V forward voltage and 130° viewing angle. However, test current differs (10mA vs. 20mA), requiring circuit current-limiting adjustment. The higher test current of the LTST-C170TBKT necessitates verification of driver circuit capability.

Q: What packaging considerations apply to the LTST-C170TBKT?

A: The LTST-C170TBKT is supplied in Cut Tape (CT) and Digi-Reel® packaging formats. Assembly equipment must support 0805 (2012 Metric) component handling. The improved MSL rating (2A vs. 4) allows extended shelf life and reduced moisture bake-out requirements.

Q: Is the wavelength shift from 505nm to 470nm acceptable for the application?

A: Wavelength compatibility depends on application-specific requirements. The 505nm blue-green spectrum differs visually from the 470nm blue spectrum. Applications requiring specific color indication must evaluate whether the spectral shift is acceptable for human perception and system requirements.
