Engineering Selection Recommendations

ACS716KLATR-25CB-NL-T (Parametric Equivalent): This part maintains identical electrical specifications and package configuration to the main part. Both components carry "Not For New Designs" status and are ROHS3 compliant. Selection of this substitute is appropriate when inventory of the primary part is unavailable, provided the application does not require active product status support.

ACS720KLATR-65AB-T (Functional Alternative): This part differs in current sensing range (65A versus 25A), supply voltage requirements (4.5V ~ 5.5V versus 3V ~ 3.6V), and output type (Ratiometric, Current versus Ratiometric, Voltage). The ACS720KLATR-65AB-T carries Active product status, providing ongoing manufacturer support. Selection of this alternative requires circuit redesign to accommodate the different supply voltage and output characteristics. This option is suitable for applications requiring higher current measurement capability and active product lifecycle support.

Frequently Asked Questions (FAQ)

Q: Can ACS716KLATR-25CB-NL-T be used as a direct replacement for ACS716KLATR-25CB-T?

A: Yes. Both parts share identical current sensing range (25A), sensitivity (18.5mV/A), supply voltage (3V ~ 3.6V), output type (Ratiometric, Voltage), and 16-SOIC package configuration. No circuit modification is required.

Q: What are the limitations of using ACS720KLATR-65AB-T as a substitute?

A: The ACS720KLATR-65AB-T requires a different supply voltage range (4.5V ~ 5.5V instead of 3V ~ 3.6V) and provides current output rather than voltage output. Circuit redesign is necessary to accommodate these differences. The higher current sensing range (65A) may introduce reduced sensitivity for applications measuring currents below 25A.

Q: Why is the ACS716KLATR-25CB-T marked "Not For New Designs"?

A: This product status indicates the manufacturer is not recommending this part for new design implementations. For new applications, the ACS720KLATR-65AB-T with Active status is the recommended alternative from Allegro MicroSystems.

Q: Are all substitute parts in the same package?

A: Yes. All listed parts use the 16-SOIC (0.295", 7.50mm Width) surface mount package, ensuring mechanical compatibility on PCB layouts.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All parts listed are ROHS3 compliant and carry identical moisture sensitivity level (MSL 3, 168 Hours) and operating temperature range (-40°C ~ 125°C).
