Key Parameters

Substitute Part Grouping Explanation

Substitution for the MIC5219-2.5BMM-TR is determined by strict equivalence across the following critical parameters:

• Fixed output voltage of 2.5V
• Output current capability of 500mA
• Maximum input voltage of 12V
• Maximum dropout voltage of 0.6V @ 500mA
• Positive output configuration with single regulator
• Enable control feature
• Over Current, Over Temperature, and Reverse Polarity protection
• 8-MSOP package with 0.118" (3.00mm) width
• Surface mount technology
• Operating temperature range of -40°C to 125°C

The MIC5219-2.5YMM-TR meets all these parameters and qualifies as a parametric equivalent. The primary distinction between the main part and substitute is packaging format (Tape & Reel vs. Cut Tape & Digi-Reel) and product status (discontinued vs. active).

Parameter Comparison

Engineering Selection Recommendations

The MIC5219-2.5YMM-TR is the direct parametric equivalent for the discontinued MIC5219-2.5BMM-TR. All electrical and mechanical specifications are identical. The substitute part offers the advantage of active product status, ensuring continued availability and supply chain reliability.

The MIC5219-2.5YMM-TR carries ROHS3 compliance, whereas the original part is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulations. The packaging format difference (Cut Tape & Digi-Reel vs. Tape & Reel) affects procurement and handling but does not impact electrical performance or PCB-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can the MIC5219-2.5YMM-TR be used as a direct replacement for the MIC5219-2.5BMM-TR?

A: Yes. Both parts are identical in electrical performance, output specifications, protection features, and package dimensions. The 8-MSOP footprint and pin configuration are equivalent, allowing direct PCB substitution.

Q: What is the difference between the two part numbers?

A: The primary differences are product status (discontinued vs. active), packaging format (Tape & Reel vs. Cut Tape & Digi-Reel), and RoHS compliance status. Electrical and mechanical specifications are identical.

Q: Does the packaging format affect circuit performance?

A: No. Packaging format (Tape & Reel vs. Cut Tape & Digi-Reel) is a procurement and handling consideration only. It does not affect electrical performance, thermal characteristics, or PCB-level functionality.

Q: Is the MIC5219-2.5YMM-TR RoHS compliant?

A: Yes, the MIC5219-2.5YMM-TR is ROHS3 compliant. The original MIC5219-2.5BMM-TR is RoHS non-compliant. This distinction is relevant for applications requiring RoHS certification.

Q: Are there any pin or footprint differences between these parts?

A: No. Both parts use the 8-MSOP package with identical pin assignments and footprint dimensions (0.118", 3.00mm width). No PCB layout modifications are required.

Q: What inventory status should I expect for the substitute part?

A: The MIC5219-2.5YMM-TR is listed as active with 3601 pieces in stock, providing reliable availability compared to the discontinued original part.
