Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Dialight 5973302602F are identified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Color: Green
• Wavelength - Dominant: 569nm
• Wavelength - Peak: 565nm
• Voltage - Forward (Vf): 2.1V
• Current - Test: 10mA
• Package / Case: 1206 (3216 Metric)
• Mounting Type: Surface Mount
• Lens Transparency: Clear
• Viewing Angle: 130°
• Size / Dimension: 3.20mm L x 1.60mm W
• Height (Max): 1.10mm

The Lite-On Inc. LTST-C150GKT qualifies as a substitute part because it matches all primary electrical and mechanical parameters. Minor variations in millicandela rating (6mcd vs 8mcd) and lens size (2.06mm x 1.60mm vs 2.00mm x 1.60mm) fall within acceptable tolerance ranges for standard LED indication applications.

Parameter Comparison

Engineering Selection Recommendations

Both the Dialight 5973302602F and Lite-On LTST-C150GKT are active products with identical regulatory compliance status. Both components are ROHS3 compliant and REACH unaffected, meeting current environmental and safety standards. The components share identical electrical characteristics (2.1V forward voltage, 10mA test current) and mechanical compatibility (1206 package, surface mount configuration).

Selection between these parts should be based on supply chain availability and packaging format requirements. The Dialight component is supplied in Strip packaging, while the Lite-On component is available in Cut Tape (CT) and Digi-Reel® formats. Both components maintain identical moisture sensitivity levels and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the Lite-On LTST-C150GKT directly replace the Dialight 5973302602F in existing designs?

A: Yes. Both components share identical electrical parameters (2.1V Vf, 10mA test current), wavelength specifications (569nm dominant, 565nm peak), and mechanical dimensions (1206 package, 3.20mm L x 1.60mm W, 1.10mm max height). The components are pin-compatible and functionally equivalent for standard LED indication applications.

Q: What is the difference in millicandela rating between these parts?

A: The Dialight 5973302602F is rated at 8mcd while the Lite-On LTST-C150GKT is rated at 6mcd. This represents a difference in luminous intensity. Selection should be based on specific brightness requirements for the application.

Q: Are there packaging differences between these substitute parts?

A: Yes. The Dialight 5973302602F is supplied in Strip packaging, while the Lite-On LTST-C150GKT is available in Cut Tape (CT) and Digi-Reel® formats. Both packaging formats are suitable for automated assembly processes.

Q: Do both components meet the same compliance standards?

A: Yes. Both the Dialight 5973302602F and Lite-On LTST-C150GKT are ROHS3 compliant and REACH unaffected. Both components have identical moisture sensitivity levels (MSL 3, 168 hours) and storage requirements.

Q: What is the lens size difference between these components?

A: The Dialight component has a lens size of 2.00mm x 1.60mm, while the Lite-On component has a lens size of 2.06mm x 1.60mm. This 0.06mm difference in the horizontal dimension falls within standard manufacturing tolerances and does not affect functional compatibility or PCB layout considerations for typical applications.
