Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5973402102F are identified based on the following critical parameters:

• Color Match: Yellow wavelength specification (588nm dominant wavelength)
• Optical Output: 6 millicandela brightness rating at 10mA test current
• Mounting Technology: Surface mount configuration for PCB assembly compatibility
• Package Compatibility: Physical dimensions and footprint suitable for 1210-class applications
• Electrical Specifications: Forward voltage and current ratings within acceptable operating range
• Compliance Status: REACH and ECCN classifications maintained

The LTST-C150YKT from Lite-On Inc. qualifies as a substitute based on matching color, brightness rating, test current, wavelength specification, and surface mount technology. Package size variation (1206 vs. 1210) is acceptable where PCB layout permits, as both are standard metric packages with compatible footprint spacing.

Parameter Comparison

Engineering Selection Recommendations

The LTST-C150YKT is suitable as a substitute for the obsolete 5973402102F based on the following factors:

• Optical Equivalence: Both components specify 6 millicandela output at 10mA test current with 588nm dominant wavelength, ensuring equivalent visual indication performance.
• Electrical Compatibility: Forward voltage of 2.1V for the LTST-C150YKT is within standard operating parameters for yellow LED applications.
• Regulatory Compliance: Both parts maintain REACH Unaffected and EAR99 ECCN classifications, ensuring equivalent compliance status.
• Product Availability: The LTST-C150YKT is classified as Active with substantial inventory availability, providing supply continuity for the obsolete 5973402102F.
• Packaging Consideration: The 1206 package is a standard metric alternative to 1210. PCB layout verification is required to confirm footprint compatibility in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the LTST-C150YKT directly replace the 5973402102F without PCB modification?

A: Direct replacement depends on PCB footprint design. The 1206 (3216 Metric) package differs from the 1210 (3125 Metric) package in dimensions. If the PCB is designed for 1210 pads, footprint adjustment or rework may be necessary. Verify pad spacing and component placement clearances before substitution.

Q: Are the optical characteristics identical between these two parts?

A: Yes. Both components specify 6 millicandela brightness at 10mA test current with 588nm dominant wavelength, providing equivalent visual indication performance in circuit applications.

Q: What is the significance of the different Moisture Sensitivity Levels (MSL)?

A: The 5973402102F specifies MSL 2A (4 Weeks) while the LTST-C150YKT specifies MSL 3 (168 Hours). Both ratings are within acceptable ranges for standard surface mount assembly processes. Storage and handling procedures should follow the more stringent requirement (MSL 2A) if both parts are used in the same production environment.

Q: Why is the 5973402102F classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The LTST-C150YKT, classified as Active, provides continued supply availability with equivalent electrical and optical specifications.

Q: Are there any compliance differences between these parts?

A: No. Both parts maintain identical REACH Unaffected and EAR99 ECCN classifications, ensuring equivalent regulatory compliance for export and use.
