1A6-TP Equivalent & Substitute Parts

Part Overview

The 1A6-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 800 V DC reverse voltage and 1 A average rectified current in an R-1 axial through-hole package. This component is classified as obsolete, making identification of equivalent substitute parts essential for ongoing design support and procurement continuity. The 1A6-TP remains functionally available through alternative part numbers that maintain identical electrical specifications and performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1A6-TP is determined by electrical parameter equivalence across the following critical specifications:

• Reverse Voltage Rating: 800 V maximum
• Forward Current Rating: 1 A average rectified current
• Forward Voltage Drop: 1.1 V maximum at 1 A
• Recovery Speed: Standard recovery characteristics >500 ns at >200 mA
• Reverse Leakage Current: 5 µA at 800 V
• Junction Capacitance: 15 pF at 4 V, 1 MHz
• Operating Temperature Range: -55°C to 150°C
• Compliance: ROHS3 Compliant

The 1N4006-E3/54 meets all electrical parameter requirements for direct substitution. While package designations differ (R-1 versus DO-204AL/DO-41), both are axial through-hole configurations with compatible physical footprints for standard PCB applications.

Parameter Comparison

Engineering Selection Recommendations

The 1N4006-E3/54 is the direct electrical equivalent for the obsolete 1A6-TP. Selection of this substitute is based on the following engineering criteria:

Electrical Equivalence: All critical electrical parameters match exactly, including reverse voltage rating, forward current capacity, forward voltage drop, recovery speed, reverse leakage current, and junction capacitance.

Compliance Status: Both parts maintain ROHS3 compliance and identical moisture sensitivity levels, ensuring regulatory and environmental compatibility with existing designs.

Product Availability: The 1N4006-E3/54 is classified as active product status with substantial inventory availability (9002 pieces), providing reliable long-term procurement compared to the obsolete 1A6-TP.

Package Compatibility: Both components utilize axial through-hole mounting configurations. The DO-204AL (DO-41) package of the 1N4006-E3/54 is mechanically compatible with standard PCB footprints designed for R-1 axial packages.

Frequently Asked Questions (FAQ)

Q: Can the 1N4006-E3/54 be used as a direct replacement for the 1A6-TP in existing designs?

A: Yes. The 1N4006-E3/54 meets all electrical specifications of the 1A6-TP, including voltage rating, current capacity, forward voltage drop, recovery speed, and operating temperature range. Both components are ROHS3 compliant with identical moisture sensitivity levels.

Q: Are there physical differences between the R-1 and DO-204AL packages?

A: Both packages are axial through-hole configurations with compatible lead spacing for standard PCB applications. The R-1 and DO-204AL (DO-41) designations refer to different package standardization systems but maintain equivalent physical footprints for component placement.

Q: Why is the 1A6-TP classified as obsolete?
