Key Parameters

Substitute Part Grouping Explanation

Substitution of the Dialight 5973602102F is determined by the following critical parameters:

• Color and Wavelength: Blue 470nm dominant wavelength is the primary functional requirement
• Mounting Type: Surface mount configuration for PCB assembly compatibility
• Package Category: 1210 (3225 Metric) or compatible footprint dimensions
• Luminous Intensity: 5mcd baseline performance specification
• Regulatory Compliance: REACH and ECCN classifications must align

The identified substitute, Lumex Opto/Components Inc. SML-LX1206USBC-TR, meets the core functional criteria of blue LED indication with 470nm peak wavelength and surface mount configuration. While the package transitions from 1210 to 1206 (3216 Metric), both are standard surface mount LED packages with compatible PCB footprint considerations. The substitute demonstrates active product status with higher luminous intensity (25mcd) and documented electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

The Lumex Opto/Components Inc. SML-LX1206USBC-TR qualifies as a functional substitute based on the following engineering criteria:

• Color and Wavelength Alignment: Both components emit blue light at 470nm, meeting the primary optical specification
• Surface Mount Compatibility: Both utilize surface mount technology for standard PCB assembly processes
• Active Product Status: The Lumex component maintains active manufacturing status, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: Both components carry REACH Unaffected and EAR99 ECCN classifications, maintaining equivalent compliance posture
• Package Transition: The shift from 1210 to 1206 package represents a standard industry transition between compatible surface mount LED footprints

The substitute demonstrates higher luminous intensity (25mcd versus 5mcd), which provides additional optical margin for indication applications. Electrical specifications (4.6V forward voltage, 20mA test current) are documented for the substitute, enabling precise circuit design validation.

Frequently Asked Questions (FAQ)

Q: Can the SML-LX1206USBC-TR directly replace the 5973602102F on existing PCBs?

A: Package footprint compatibility requires evaluation. The 1210 (3225 Metric) and 1206 (3216 Metric) packages have different dimensions. PCB layout modifications may be necessary. The 1206 package is smaller (3.20mm L x 1.60mm W versus 3225 Metric dimensions), requiring footprint adjustment during board redesign.

Q: What is the significance of the higher millicandela rating in the substitute?

A: The SML-LX1206USBC-TR delivers 25mcd compared to the original 5mcd specification. This increased luminous intensity provides greater optical visibility for indication purposes. Circuit design must account for this difference through appropriate current limiting resistor selection to maintain desired brightness levels.

Q: Are there electrical specification differences that affect circuit design?

A: The substitute provides documented electrical parameters (4.6V forward voltage, 20mA test current, 140° viewing angle) that were not specified for the original component. These specifications enable precise circuit design. The original component's electrical characteristics must be inferred from typical blue LED performance or obtained from Dialight technical documentation.

Q: How do moisture sensitivity levels compare?

A: The original component specifies MSL 2A (4 Weeks), while the substitute specifies MSL 3 (168 Hours). Both classifications indicate moderate moisture sensitivity requiring controlled storage and handling. The substitute allows extended storage periods under standard conditions.

Q: What compliance certifications apply to both components?

A: Both components carry REACH Unaffected status and EAR99 ECCN classification, indicating equivalent regulatory treatment for export and environmental compliance purposes.
