Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT9163-50GL are qualified based on the following critical parameters:

• Fixed 5V output voltage matching the main part specification
• 500mA output current capability
• Surface mount SOT-223 package compatibility (TO-261-4, TO-261AA)
• Maximum input voltage rating of 15V or greater
• Operating temperature range of -40°C to 125°C or wider
• Active product status
• ROHS3 compliance and REACH unaffected status

The MIC5209-5.0YS meets all substitution criteria within these allowed electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the RT9163-50GL and MIC5209-5.0YS are active products with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The MIC5209-5.0YS provides a higher maximum input voltage rating (16V versus 15V) and includes reverse polarity protection in addition to over-current and over-temperature protection. Both devices operate across the identical temperature range and deliver the required 500mA output at 5V in compatible SOT-223 surface mount packages. Selection between these parts should be based on specific application input voltage requirements and the value of additional reverse polarity protection.

Frequently Asked Questions (FAQ)

Q: Can the MIC5209-5.0YS directly replace the RT9163-50GL?

A: Yes, the MIC5209-5.0YS is a direct substitute. Both devices provide fixed 5V output at 500mA in compatible SOT-223 packages with identical operating temperature ranges and regulatory compliance.

Q: What is the difference in input voltage ratings?

A: The RT9163-50GL accepts maximum input voltage of 15V, while the MIC5209-5.0YS accepts 16V. Applications operating at or near 15V input should verify compatibility with the specific regulator selected.

Q: Are the package footprints identical?

A: Both parts use TO-261-4 and TO-261AA case styles (SOT-223 family). The MIC5209-5.0YS is specified as SOT-223-3, which maintains mechanical and electrical compatibility with SOT-223 footprints.

Q: What additional protection does the MIC5209-5.0YS provide?

A: The MIC5209-5.0YS includes reverse polarity protection in addition to over-current and over-temperature protection, whereas the RT9163-50GL provides over-current and over-temperature protection only.

Q: Are both parts RoHS compliant?

A: Yes, both the RT9163-50GL and MIC5209-5.0YS are ROHS3 compliant and REACH unaffected.
