Key Parameters

Substitute Part Grouping Explanation

Substitute grouping is strictly determined by matching the following key parameters: function (step-down), topology (buck), output configuration (positive or positive/negative), output type (fixed), number of outputs (1), voltage input range, output voltage, output current rating, frequency, package/case, mounting type, and regulatory compliance (RoHS, REACH, ECCN). Only parts with equivalent electrical and mechanical characteristics in these fields have been grouped as substitutes.

Parameter Comparison

Engineering Selection Recommendations

Selection of substitute parts for LM2575T-5.0 should be based on product status and regulatory compliance. The original part is obsolete; all substitutes listed have active product status and ROHS3 compliance, with unaffected REACH registration and the same ECCN classification. Package and mounting type are identical across all listed substitutes.

Frequently Asked Questions (FAQ)

Q1: Which parameters are critical for substituting LM2575T-5.0?
Only function, topology, output configuration, output type, input voltage range, output voltage, output current, switching frequency, operating temperature, mounting type, package/case, number of outputs, and compliance statuses are considered.

Q2: Are all substitute parts compatible with the same PCB footprint?
All listed substitutes use the TO-220-5 package with through-hole mounting, ensuring direct compatibility.

Q3: How do substitute parts compare in electrical performance?
All substitutes provide the same fixed 5V output and operate at a 52kHz switching frequency. Output current capability differs on LM2576T-005G (3A).

Q4: What regulatory certificates must be reviewed during part selection?
Ensure substitute parts are ROHS3 Compliant and REACH Unaffected with ECCN: EAR99, exactly as specified in the provided parameters.

Q5: Does the operating temperature range differ between the main and substitute parts?
All substitutes operate across the same temperature range of -40°C to 125°C (TJ), as per provided data.
