Substitute Part Grouping Explanation

Substitute selection is strictly determined using the following key parameters: Type (Non-Isolated PoL Module), number of outputs (1), output voltage (3.3V), maximum output current (1.2A), input voltage range, compatible application (ITE Commercial), features, mounting type, and package dimensions. Substitution is only considered if these parameters are matched or encompassed within the operational envelope of the substitute part.

Engineering Selection Recommendations

LXDC2SCAAB-352 is classified as obsolete. MPM3810GQB-33-P is listed as active, ROHS3 compliant, and REACH unaffected. Product status and available compliance documentation confirm suitability for direct substitution within the defined application scope. Substitution must only be enacted where these documented specifications and certifications are met.

Frequently Asked Questions (FAQ)

Q: What parameters are essential for substituting Non-Isolated PoL DC DC Converters?
A: Substitution requires strict alignment in module type, output voltage, current rating, input voltage range, and application category.

Q: How does package type affect substitution?
A: Both parts support surface mount applications. However, differences in package size and configuration require evaluation for mechanical fit and PCB layout compatibility.

Q: Is the substitute part compliant with RoHS and REACH regulations?
A: The MPM3810GQB-33-P is documented as ROHS3 compliant and REACH unaffected.

Q: Are all protection and control features identical between the two parts?
A: The substitute MPM3810GQB-33-P provides OCP, OTP, and UVLO. Remote On/Off and SCP features should be reviewed for specific application needs based on the parameters provided.

Q: What is the operating temperature range for the substitute part?
A: MPM3810GQB-33-P supports an operating temperature range of -40°C ~ 125°C.

Q: Is mechanical compatibility guaranteed?
A: Compatibility is based solely on the provided package and size parameters. Confirm dimensions and mounting type as per documented specifications.
