Substitute Part Grouping Explanation

Substitute parts for the MST5960C are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

• Display Configuration: 3-character, 7-segment, common cathode architecture
• Electrical Specifications: 2V forward voltage and 20mA test current
• Optical Properties: Red color with 635nm peak wavelength and 2.2mcd brightness rating
• Physical Form Factor: 0.52" digit height and 30-DIP package footprint
• Dimensional Compatibility: Overall package dimensions within acceptable tolerance for PCB mounting

The LTC-5336HR from Lite-On Inc. meets all substitution criteria, maintaining identical electrical performance and package compatibility while offering active product status.

Engineering Selection Recommendations

The LTC-5336HR serves as a direct substitute for the MST5960C in applications requiring a 3-character red 7-segment common cathode display. Selection should be based on the following factors:

Product Status: The MST5960C is obsolete, while the LTC-5336HR maintains active product status, ensuring continued availability and supply chain reliability.

Compliance: The LTC-5336HR is RoHS3 compliant, meeting current environmental and regulatory requirements. Both parts carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

Electrical Compatibility: Identical forward voltage (2V) and test current (20mA) specifications ensure direct circuit compatibility without modification to existing designs.

Physical Compatibility: Dimensional variations between the two parts are minimal (height difference of 0.008", width difference of 0.006"), maintaining PCB mounting compatibility within standard tolerance ranges.

Power Considerations: The LTC-5336HR maximum power dissipation is 75mW compared to 70mW for the MST5960C, representing a 5mW increase that remains within typical thermal design margins for DIP-packaged components.

Frequently Asked Questions (FAQ)

Q: Can the LTC-5336HR replace the MST5960C in existing designs without PCB modification?

A: Yes. Both parts share identical electrical specifications (2V forward voltage, 20mA test current), common cathode configuration, and 30-DIP package footprint. Dimensional differences are within standard PCB tolerance ranges for through-hole mounting.

Q: What is the significance of the MST5960C being obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The LTC-5336HR, with active product status, provides a viable alternative for new production runs and replacement inventory.

Q: Are there any compliance differences between these parts?

A: The LTC-5336HR is RoHS3 compliant, meeting current environmental standards. Both parts share identical ECCN and HTSUS classifications for export and tariff purposes.

Q: How do the brightness ratings compare?

A: Both parts specify 2.2mcd millicandela rating and 635nm peak wavelength, ensuring equivalent optical performance in display applications.

Q: What is the impact of the 5mW power dissipation difference?

A: The LTC-5336HR maximum power dissipation of 75mW versus 70mW for the MST5960C represents a minor increase. This difference is negligible in typical circuit designs and does not require thermal design modifications.

Q: Are the physical dimensions identical?

A: Dimensions are nearly identical with minor variations: height differs by 0.008" (0.20mm), width by 0.006" (0.15mm), and depth remains constant at 0.276" (7.00mm). These variations fall within standard PCB design tolerances.
