Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Dialight 5973006602F is determined by the following criteria:

• Package compatibility: 0805 (2012 Metric) surface mount form factor
• Electrical parameters: Forward voltage 2V, test current 10mA
• Optical characteristics: Red color, viewing angle 130°
• Regulatory compliance: ROHS3 compliant, REACH unaffected status
• Wavelength range: Dominant wavelength within red spectrum (621nm–630nm acceptable)
• Luminous intensity: Millicandela rating sufficient for indication applications

The Lite-On Inc. LTST-C170EKT meets these substitution criteria with compatible electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the Dialight 5973006602F and Lite-On LTST-C170EKT are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The components share identical package dimensions, forward voltage, test current, and viewing angle specifications. The primary difference is luminous intensity: the Dialight part provides 6mcd while the Lite-On substitute provides 2mcd. Selection between these parts depends on application brightness requirements. Both components are suitable for standard indication applications where the specified luminous intensity meets circuit design parameters.

Frequently Asked Questions (FAQ)

Q: Can the Lite-On LTST-C170EKT directly replace the Dialight 5973006602F in existing designs?

A: Direct replacement is possible if the application brightness requirement does not exceed 2mcd. The Lite-On part provides lower luminous intensity (2mcd versus 6mcd) while maintaining identical electrical parameters and package compatibility.

Q: Are there differences in wavelength between these parts?

A: The Dialight part has a dominant wavelength of 630nm while the Lite-On part has a dominant wavelength of 621nm. Both fall within the red spectrum and are visually compatible for indication applications.

Q: What are the packaging differences?

A: The Dialight 5973006602F is supplied in Strip packaging while the Lite-On LTST-C170EKT is supplied in Tape & Reel (TR) packaging. Both use the same 0805 (2012 Metric) component form factor.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the Dialight 5973006602F and Lite-On LTST-C170EKT are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the moisture sensitivity level difference?

A: The Dialight part has MSL 3 (168 Hours) while the Lite-On part has MSL 2A (4 Weeks). The Lite-On part requires less stringent moisture control during storage and handling.
