PROD Technology Co., Ltd.
A strong alternative from the same series with higher impedance (1kΩ) and slightly higher DCR.
PCAQ3216B-601ATE is a 1206 common mode choke from PROD Technology, offering 600Ω impedance at 100MHz for EMI suppression. This review identifies several alternatives with varying impedance and DCR characteristics.
Impedance and DCR differences require circuit validation.
All viable candidates are in a 1206 4-pin package, but pinout must be verified.
No exact drop-in replacement is confirmed, but PCAQ3216B-102T025 is a very close functional alternative from the same manufacturer and series.
PCAQ3216B-102T025 from the same series offers a similar profile with higher impedance, providing potentially better filtering.
The primary risk is mismatch in impedance and DC resistance (DCR), which can affect EMI filtering effectiveness and power efficiency.
