Parameter Comparison

Engineering Selection Recommendations

The UC3707N is the direct substitute for the UC3707NG4. Both parts are manufactured by Texas Instruments and maintain identical electrical and mechanical specifications across all functional parameters. The primary distinction is product status: the UC3707NG4 is discontinued at DiGi Electronics, while the UC3707N remains in active production status.

Both parts carry ROHS3 compliance and are unaffected by REACH regulations, ensuring regulatory alignment for new designs and legacy system support. The UC3707N is available in higher inventory quantities (1852 pcs) compared to the UC3707NG4 (1072 pcs), providing improved procurement reliability.

For applications currently using UC3707NG4, direct substitution with UC3707N requires no circuit modifications, as all electrical characteristics, pin configurations, and thermal operating ranges are identical.

Frequently Asked Questions (FAQ)
