Parameter Comparison

Engineering Selection Recommendations

Both TE1303.3 and TE1303.3-E3 are electrically and mechanically equivalent aluminum electrolytic capacitors suitable for direct substitution in through-hole applications requiring 8 µF at 50 V.

The TE1303.3-E3 variant offers ROHS3 compliance, making it the preferred selection for applications subject to RoHS3 regulatory requirements. The original TE1303.3 remains suitable for applications without RoHS compliance mandates.

Both parts maintain identical electrical performance, thermal ratings, and physical form factors, ensuring seamless integration into existing PCB designs and assembly processes.
