Key Parameters

Substitute Part Grouping Explanation

Substitute selection for Non-Isolated PoL Module DC-DC converters is strictly based on the following allowed parameters:

• Module type and number of outputs
• Input voltage range compatibility
• Output voltage(s)
• Output current capability
• Operating temperature range
• Mounting type
• RoHS, MSL, REACH, and ECCN compliance

Only substitute parts matching or exceeding these specifications are included. All substitute relationships are strictly determined by these key parameters.

Parameter Comparison

Engineering Selection Recommendations

PTH04T261WAZ is listed as obsolete. Substitute selection should reference active alternatives that are ROHS3 compliant and MSL 3 rated, with an EAR99 ECCN and REACH unaffected status. TPSM82866AA0HRDMR matches these criteria and is listed as active, providing equivalent module function, number of outputs, and comparable mounting and compliance.

Frequently Asked Questions (FAQ)

Q: What are the essential substitution criteria for the PTH04T261WAZ DC-DC Converter?
