Parameter Comparison

Engineering Selection Recommendations

The LM76202QPWPRQ1 is the designated manufacturer-recommended substitute for the obsolete MP6914DN-LF. Selection of this alternative is supported by:

Product Status Continuity: The substitute maintains active production status, ensuring availability for current and future procurement cycles, whereas the original part is obsolete.

Regulatory Compliance: Both components maintain identical RoHS3, REACH, and export classification status, eliminating compliance re-qualification requirements.

Automotive Grade Qualification: The LM76202QPWPRQ1 carries AEC-Q100 automotive qualification, providing enhanced reliability assurance for mission-critical applications.

Package Consideration: The substitute utilizes a 16-pin PowerTSSOP package compared to the original 8-pin SOIC package. PCB layout modifications are required to accommodate the different pin count and footprint geometry.

Frequently Asked Questions (FAQ)

Q: Can the LM76202QPWPRQ1 be used as a direct pin-for-pin replacement for the MP6914DN-LF?

A: No. The LM76202QPWPRQ1 uses a 16-pin PowerTSSOP package versus the 8-pin SOIC package of the original part. PCB redesign is necessary to accommodate the different pin configuration and footprint dimensions.

Q: What are the key functional differences between these two OR controllers?

A: Both components function as OR controllers for power management applications. The LM76202QPWPRQ1 provides additional features including N+1 ORing capability, specified delay times (80 µs ON, 9 µs OFF), and defined output current specifications (2.2A maximum), which may exceed the requirements of the original MP6914DN-LF application.

Q: Are there any compliance concerns when substituting the LM76202QPWPRQ1?

A: No compliance concerns exist. Both parts maintain identical RoHS3, REACH, and EAR99 export classification status. The substitute carries AEC-Q100 automotive qualification, which provides additional reliability assurance.

Q: What is the impact of the different Moisture Sensitivity Levels (MSL)?

A: The MP6914DN-LF specifies MSL 2A (4 weeks), while the LM76202QPWPRQ1 specifies MSL 3 (168 hours). The substitute allows extended shelf life before reflow soldering, reducing moisture-related handling constraints during manufacturing.

Q: Is the LM76202QPWPRQ1 suitable for the same voltage and current operating ranges?

A: The LM76202QPWPRQ1 specifies a supply voltage range of 4.2V to 60V and maximum output current of 2.2A. Application-specific verification is required to confirm compatibility with the original MP6914DN-LF operating parameters.
