Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1N5402-AP is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 200 V
• Current - Average Rectified (Io): 3 A
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 3 A
• Speed: Standard Recovery >500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 5 µA @ 200 V
• Package / Case: DO-201AD, Axial
• Mounting Type: Through Hole
• Operating Temperature - Junction: -55°C to 150°C

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The substitute parts identified below meet all critical electrical parameters and mechanical requirements. Capacitance variation (25 pF vs. 40 pF @ 4V, 1MHz) is within acceptable tolerance for general-purpose rectifier applications and does not affect substitution eligibility. One substitute variant includes automotive-grade qualification (AEC-Q101), providing additional qualification for applications requiring automotive compliance.

Parameter Comparison

Engineering Selection Recommendations

1N5402G A0G (Taiwan Semiconductor Corporation)

This part is a direct parametric equivalent to the 1N5402-AP with active product status. All electrical specifications match the original component, including reverse voltage, rectified current, forward voltage, recovery speed, and reverse leakage current. The part is ROHS3 compliant and carries unlimited moisture sensitivity rating. This variant is suitable for general-purpose rectifier applications where automotive qualification is not required.

1N5402GHA0G (Taiwan Semiconductor Corporation, Automotive Grade)

This part is a direct parametric equivalent with automotive-grade qualification (AEC-Q101). All electrical specifications are identical to the standard variant. Selection of this part is appropriate for applications requiring automotive compliance or operating in automotive environments. The automotive qualification provides additional process and reliability assurance.

Both substitute parts are manufactured by Taiwan Semiconductor Corporation and are currently in active production with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the 1N5402G A0G directly replace the 1N5402-AP in existing designs?

A: Yes. The 1N5402G A0G meets all electrical and mechanical parameters of the 1N5402-AP. Both components are rated for 200 V reverse voltage, 3 A average rectified current, and use the DO-201AD axial through-hole package. No circuit modifications are required.

Q: What is the difference between 1N5402G A0G and 1N5402GHA0G?

A: Both parts are electrically identical and meet the same electrical specifications. The 1N5402GHA0G carries automotive-grade qualification (AEC-Q101), making it suitable for automotive applications. Selection depends on application requirements and compliance mandates.

Q: Does the capacitance difference (40 pF vs. 25 pF) affect substitution?

A: No. The capacitance variation between the main part (40 pF @ 4V, 1MHz) and substitute parts (25 pF @ 4V, 1MHz) is within acceptable tolerance for general-purpose rectifier diodes and does not impact functional substitution.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both 1N5402G A0G and 1N5402GHA0G are ROHS3 compliant, matching the compliance status of the original 1N5402-AP.

Q: What is the operating temperature range for the substitute parts?

A: Both substitute parts operate across the same junction temperature range as the original: -55°C to 150°C.

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

A: Yes. Both substitute parts use the DO-201AD axial through-hole package, identical to the 1N5402-AP. No PCB layout modifications are necessary.

Q: Why is the 1N5402-AP listed as obsolete?

A: The 1N5402-AP is no longer in active production by Micro Commercial Co. The substitute parts from Taiwan Semiconductor Corporation provide equivalent functionality with active product status and ongoing availability.
