Substitute Part Grouping Explanation

Substitution for the LM2575TV-012 is determined by strict equivalence across the following critical parameters: fixed 12V output voltage, 1A output current rating, buck topology, TO-220-5 package configuration, 52kHz switching frequency, and compatible operating temperature range. Substitute parts must maintain identical electrical performance characteristics and mechanical compatibility to ensure direct replacement without circuit redesign.

The substitute parts are grouped as follows:

Direct Manufacturer Equivalent: LM2575TV-012G (onsemi) — identical electrical specifications with improved RoHS3 compliance status.

Cross-Manufacturer Equivalent: TL2575HV-12IKV (Texas Instruments) — functionally equivalent with extended input voltage range (4.75V to 60V) and active product status.

Parameter Comparison

Engineering Selection Recommendations

LM2575TV-012G is the direct equivalent from onsemi with identical electrical and mechanical specifications. This part offers improved regulatory compliance through RoHS3 certification while maintaining the same functional performance. Selection of this part is appropriate for applications requiring onsemi sourcing continuity.

TL2575HV-12IKV from Texas Instruments provides functional equivalence with the additional advantage of active product status and extended maximum input voltage rating (60V versus 40V). This part is suitable for applications requiring long-term availability assurance and higher input voltage tolerance. Both substitute parts maintain identical output voltage, current rating, switching frequency, package configuration, and operating temperature range as the original LM2575TV-012.

Frequently Asked Questions (FAQ)

Q: Can LM2575TV-012G be used as a direct replacement for LM2575TV-012?

A: Yes. Both parts share identical electrical specifications, output voltage (12V), output current (1A), switching frequency (52kHz), and TO-220-5 package configuration. The primary difference is improved RoHS3 compliance status in the -012G variant.

Q: What is the key difference between LM2575TV-012G and TL2575HV-12IKV?
