Substitute Part Grouping Explanation

Substitution of the DDZX22D-13 is based on strict equivalence of electrical and mechanical parameters within the DDZX22 product family. The substitute part DDZX22D-7 maintains identical specifications across all critical parameters: 22 V nominal Zener voltage, ±3% tolerance, 300 mW maximum power, 30 Ohms maximum impedance, 50 nA reverse leakage current, 900 mV forward voltage, and identical operating temperature range. Both parts utilize the SOT-23-3 surface mount package and share the same base product number designation. The substitution is valid based on matching voltage rating, power rating, impedance characteristics, leakage specifications, forward voltage characteristics, temperature operating range, and package compatibility.

Parameter Comparison

Engineering Selection Recommendations

The DDZX22D-7 is a direct parametric equivalent to the DDZX22D-13. Both components are manufactured by Diodes Incorporated with Active product status and identical electrical ratings. Selection between these parts is based on availability and supply chain requirements rather than technical performance differences. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The DDZX22D-7 currently maintains higher inventory levels (6050 Pcs) compared to the DDZX22D-13 (769 Pcs), which may influence procurement decisions for high-volume applications. No technical performance trade-offs exist between these alternatives.

Frequently Asked Questions (FAQ)

Q: Can DDZX22D-7 be used as a direct replacement for DDZX22D-13?

A: Yes. Both parts are identical in electrical specifications, including 22 V Zener voltage, 300 mW power rating, impedance, leakage current, and forward voltage characteristics. Both use SOT-23-3 surface mount packaging and operate across the same temperature range.

Q: Are there any package compatibility differences between DDZX22D-13 and DDZX22D-7?
