Substitute Part Grouping Explanation

Substitution of the DDZX12C-13 is determined by strict equivalence across the following critical parameters:

• Zener voltage rating: 12 V nominal
• Tolerance specification: ±3%
• Maximum power dissipation: 300 mW
• Impedance (Max): 12 Ohms
• Reverse leakage current: 100 nA @ 9.1 V
• Forward voltage: 900 mV @ 10 mA
• Operating temperature range: -65°C ~ 150°C
• Package type: SOT-23-3 surface mount
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

The substitute part DDZX12C-7 meets all electrical and mechanical parameters specified for the main part. The primary distinction between these parts is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The DDZX12C-7 is a direct electrical and mechanical equivalent to the DDZX12C-13. All critical electrical parameters, operating characteristics, and regulatory compliance specifications are identical. The DDZX12C-7 maintains active product status with Diodes Incorporated, ensuring ongoing availability and supply chain continuity.

The primary differences are packaging format and product lifecycle status. The DDZX12C-13 is supplied in bulk packaging, while the DDZX12C-7 is supplied in Tape & Reel format. For applications requiring bulk quantities or specific packaging configurations, component procurement should specify the appropriate packaging variant.

Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Frequently Asked Questions (FAQ)
