Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MST5950C is determined by strict alignment with the following electrical and mechanical parameters:

• Display Configuration: 3-character, 7-segment, common anode architecture
• Physical Compatibility: 0.52" digit height and 30-DIP package footprint
• Electrical Specifications: Forward voltage range and test current compatibility
• Color and Wavelength: Red LED emission

The LTC-5836P from LITEON meets these core substitution criteria. Both devices share identical character count, display type, common anode configuration, digit size, and package format. Electrical parameters remain within acceptable operational ranges for direct substitution in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

The LTC-5836P represents a direct functional substitute for the MST5950C based on matching core electrical and mechanical specifications. The LTC-5836P offers the advantage of active product status, ensuring continued availability and supply chain reliability. The forward voltage differential of 0.1V (2V to 2.1V) falls within standard circuit design tolerances for LED display applications. The LTC-5836P carries RoHS3 compliance certification, providing regulatory advantage for new designs. Both devices maintain identical package footprints and pinout configurations, enabling direct PCB-level substitution without layout modification.

Frequently Asked Questions (FAQ)

Q: Can the LTC-5836P replace the MST5950C in existing designs?

A: Yes. Both devices share identical 3-character 7-segment common anode configuration, 0.52" digit height, and 30-DIP package format. The 0.1V forward voltage difference is within standard design margins for LED display circuits.

Q: What are the physical compatibility considerations?

A: The LTC-5836P dimensions (17.50mm x 37.85mm x 7.00mm) are within 0.2mm tolerance of the MST5950C (17.70mm x 38.00mm x 7.00mm). Both devices use identical 30-DIP (0.600", 15.24mm) package spacing, ensuring direct PCB compatibility.

Q: How do the brightness specifications compare?

A: The MST5950C provides 2.2mcd at 635nm wavelength, while the LTC-5836P provides 0.8mcd at 697nm wavelength. The wavelength difference reflects standard red LED manufacturing variations. Circuit design should account for the brightness differential through appropriate current limiting resistor selection.

Q: What compliance certifications apply to the substitute part?

A: The LTC-5836P is RoHS3 compliant and carries Moisture Sensitivity Level 1 (Unlimited). Both devices are classified under ECCN EAR99 and HTSUS 8541.41.0000.

Q: Why is the MST5950C obsolete?

A: The MST5950C is classified as obsolete by onsemi. The LTC-5836P from LITEON maintains active product status, providing long-term supply availability for replacement and new production requirements.
