Substitute Part Grouping Explanation

Substitution of the CZRQR11VB-HF with the CZRQC11VB-HF is based on equivalence across all critical electrical and mechanical parameters. Both parts share identical nominal Zener voltage (11 V), maximum power rating (125 mW), impedance specification (18 Ohms maximum), reverse leakage current (100 nA @ 8.4 V), forward voltage drop (900 mV @ 10 mA), operating temperature range (-55°C to 125°C), and package form factor (0402/SOD-923F surface mount). The tolerance specification differs marginally (±2% versus ±2.45%), remaining within acceptable substitution criteria for Zener diode applications. Both parts maintain ROHS3 compliance, MSL Level 1 rating, and identical ECCN and HTSUS classifications.

The primary distinction is product status: CZRQR11VB-HF is obsolete, while CZRQC11VB-HF is active with superior inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The CZRQC11VB-HF is the direct equivalent for CZRQR11VB-HF replacement. Selection is based on the following engineering criteria:

Product Status: CZRQC11VB-HF maintains active product status with confirmed inventory availability (936 pcs), whereas CZRQR11VB-HF is obsolete. For new designs and ongoing production, CZRQC11VB-HF is the appropriate selection.
