Substitute Part Grouping Explanation

Substitution of the 1A5-AP is determined by electrical and mechanical parameter equivalence across the following criteria:

Electrical Parameters (Critical):

• Voltage - DC Reverse (Vr) (Max): 600 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A
• Speed: Standard Recovery >500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 5 µA @ 600 V
• Capacitance @ Vr, F: 15pF @ 4V, 1MHz

Mechanical Parameters (Critical):

• Mounting Type: Through Hole
• Operating Temperature - Junction: -55°C ~ 150°C

Compliance Parameters:

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

The 1N4005E-E3/54 manufactured by Vishay General Semiconductor - Diodes Division meets all electrical and mechanical requirements for direct substitution. While the package designation differs (DO-204AL/DO-41 versus R-1), both are axial through-hole configurations with equivalent physical and electrical characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 1N4005E-E3/54 be used as a direct replacement for the 1A5-AP in existing designs?

A: Yes. The 1N4005E-E3/54 meets all electrical specifications of the 1A5-AP, including voltage rating, current rating, forward voltage, recovery speed, and leakage current. Both are through-hole axial components with identical operating temperature ranges.

Q: What is the difference between the R-1 and DO-204AL package designations?

A: R-1 and DO-204AL (DO-41) are both axial through-hole package styles for rectifier diodes. The designations reflect different naming conventions used by manufacturers. Both packages are mechanically and electrically compatible for through-hole circuit board applications.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the 1A5-AP and 1N4005E-E3/54 are ROHS3 compliant, carry identical ECCN and HTSUS classifications, and share the same moisture sensitivity level rating.

Q: Why is the 1A5-AP classified as obsolete?

A: The 1A5-AP is no longer in active production. The 1N4005E-E3/54 provides equivalent electrical and mechanical performance and is actively manufactured, making it the recommended choice for new designs and component replenishment.

Q: Are the electrical characteristics identical between these two diodes?

A: Yes. Both parts share identical specifications for reverse voltage (600V), average rectified current (1A), forward voltage drop (1.1V @ 1A), recovery speed (>500ns), reverse leakage current (5µA @ 600V), and junction capacitance (15pF @ 4V, 1MHz).
