Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MST5150C is determined by strict alignment across the following critical parameters:

• Character Configuration: 3-character display requirement
• Segment Type: 7-segment architecture
• Common Pin Type: Common anode configuration
• Color Specification: Red wavelength at 697nm peak
• Digit Height: 0.52" (13.21mm) digit size
• Electrical Ratings: 2.1V forward voltage and 20mA test current
• Optical Output: 0.8mcd millicandela rating
• Package Format: 30-DIP (0.600", 15.24mm) dual-in-line package

The LTC-5836P from LITEON meets all specified parameters within acceptable dimensional tolerances and electrical characteristics, qualifying as a direct substitute.

Engineering Selection Recommendations

The LTC-5836P represents a functionally equivalent substitute for the obsolete MST5150C. Selection between these components should be based on the following factors:

Product Availability: The MST5150C is obsolete with limited remaining inventory (977 pcs). The LTC-5836P maintains active product status with current manufacturing support (753 pcs in stock), ensuring long-term supply chain viability.

Compliance Status: The LTC-5836P carries RoHS3 compliance certification, whereas the MST5150C does not specify RoHS compliance. Both components share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

Physical Compatibility: Dimensional variance between the two parts is minimal (0.008" height difference, 0.006" width difference). Both maintain identical 30-DIP package footprint and 0.276" depth, ensuring PCB layout compatibility without redesign.

Electrical Equivalence: Identical forward voltage (2.1V), test current (20mA), optical output (0.8mcd), wavelength (697nm), and power dissipation (40mW) specifications confirm direct functional substitution.

Frequently Asked Questions (FAQ)

Q: Can the LTC-5836P replace the MST5150C in existing designs without PCB modification?

A: Yes. Both components use identical 30-DIP package footprint with matching pin spacing (0.600", 15.24mm). Physical dimensions differ by less than 0.01", which falls within standard PCB tolerance ranges. No layout changes are required.

Q: Are the electrical characteristics identical between MST5150C and LTC-5836P?

A: Yes. Forward voltage (2.1V), test current (20mA), wavelength (697nm), millicandela rating (0.8mcd), and maximum power dissipation (40mW) are identical. Both operate as common anode 3-character 7-segment red displays.

Q: Why is the MST5150C listed as obsolete?

A: Obsolete status indicates the manufacturer (onsemi) has discontinued production. The LTC-5836P from LITEON provides equivalent functionality with active manufacturing support.

Q: What is the significance of RoHS3 compliance on the LTC-5836P?

A: RoHS3 compliance indicates the LTC-5836P meets current European Union Restriction of Hazardous Substances regulations. This is relevant for applications subject to RoHS requirements or for future supply chain transitions.

Q: Are there any performance differences in display brightness or color between these parts?

A: No. Both components specify identical millicandela rating (0.8mcd) and wavelength peak (697nm), ensuring equivalent brightness and color characteristics.

Q: What is the moisture sensitivity level for both components?

A: Both MST5150C and LTC-5836P carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.
