Engineering Selection Recommendations

1N4004-G (Comchip Technology)

The 1N4004-G is an active, ROHS3-compliant substitute with identical voltage and current ratings. Forward voltage is lower at 1.1 V compared to 1.2 V on the main part. Recovery speed is standard (>500ns) rather than fast recovery. This part is suitable for applications where recovery speed is not a critical design parameter and lower forward voltage drop is beneficial.

FR104G A0G (Taiwan Semiconductor Corporation)

The FR104G A0G is an active, ROHS3-compliant substitute with identical voltage and current ratings. Forward voltage is higher at 1.3 V, and reverse recovery time is faster at 150 ns compared to 200 ns on the main part. Capacitance is lower at 10 pF. This part is suitable for applications requiring faster recovery characteristics.

UF4005-G (Comchip Technology)

The UF4005-G is an obsolete, ROHS3-compliant part with identical voltage and current ratings. Forward voltage is 1.3 V, and reverse recovery time is significantly faster at 50 ns. Capacitance is higher at 20 pF. Due to obsolete status, this part should be selected only when existing inventory must be maintained or when superior recovery speed characteristics are required and alternative active parts are unavailable.

Frequently Asked Questions (FAQ)

Q: Can the 1N4004-G replace the 1N4936GP-AP in all applications?

A: The 1N4004-G matches the voltage and current ratings and operates across the same temperature range. The primary difference is recovery speed classification (standard vs. fast recovery). In applications where switching speed is not critical, the 1N4004-G is electrically compatible. Forward voltage is slightly lower (1.1 V vs. 1.2 V), which may reduce power dissipation.

Q: What is the significance of reverse recovery time differences?

A: Reverse recovery time (trr) affects switching performance in high-frequency applications. The 1N4936GP-AP has 200 ns recovery time, while the FR104G A0G has 150 ns and the UF4005-G has 50 ns. Faster recovery reduces switching losses and is beneficial in switching power supplies and high-frequency rectification circuits. Standard recovery parts like the 1N4004-G are suitable for line-frequency and low-frequency applications.

Q: Are all substitute parts available in the same package?

A: All substitute parts are available in DO-204AL, DO-41, and Axial package configurations. The supplier device package designation may vary (DO-41 vs. DO-204AL), but physical dimensions and pin compatibility remain consistent for through-hole mounting.

Q: Why is the UF4005-G listed as obsolete?

A: The UF4005-G is classified as obsolete by the manufacturer. While inventory is available, this part should not be selected for new designs. Use active alternatives such as 1N4004-G or FR104G A0G for ongoing production and new applications.

Q: Do all substitute parts meet the same compliance standards?

A: All listed substitute parts are ROHS3 compliant, REACH unaffected, and carry the same ECCN (EAR99) and HTSUS (8541.10.0080) classifications as the main part. Moisture sensitivity level is 1 (Unlimited) for all parts.

Q: What is the difference between fast recovery and standard recovery diodes?

A: Fast recovery diodes have reverse recovery times ≤ 500 ns and are designed for switching applications. Standard recovery diodes have reverse recovery times > 500 ns and are optimized for line-frequency rectification. The 1N4936GP-AP and FR104G A0G are fast recovery types, while the 1N4004-G is standard recovery.
