Equivalent & Substitute Parts for 1A6-AP

Part Overview

The 1A6-AP 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 active equivalent parts essential for ongoing design support and procurement continuity. The substitute part 1N4006-E3/54 provides functional equivalence with identical electrical specifications and active product status.

Substitute Part Grouping Explanation

Substitution of the 1A6-AP with the 1N4006-E3/54 is based on electrical parameter equivalence across all critical specifications. Both components share identical ratings for reverse voltage (800 V), average rectified current (1 A), forward voltage drop (1.1 V @ 1 A), reverse leakage current (5 µA @ 800 V), and junction temperature range (-55°C to 150°C). Both employ standard recovery speed technology with recovery time exceeding 500 ns at currents greater than 200 mA. Capacitance characteristics are identical at 15 pF measured at 4 V and 1 MHz. The primary distinction lies in package configuration: the 1A6-AP uses an R-1 axial package, while the 1N4006-E3/54 uses a DO-204AL (DO-41) axial package. Both packages are through-hole mounted and mechanically compatible in standard PCB layouts. The 1N4006-E3/54 maintains active product status and ROHS3 compliance, providing long-term availability advantages over the obsolete 1A6-AP.

Engineering Selection Recommendations

The 1N4006-E3/54 is the appropriate substitute for the obsolete 1A6-AP based on complete electrical parameter equivalence and active product status. All critical electrical specifications—reverse voltage, forward current, forward voltage drop, reverse leakage, recovery speed, and capacitance—are identical between the two components. Both components maintain ROHS3 compliance and unlimited moisture sensitivity classification, ensuring regulatory and environmental compatibility.

The package difference between R-1 and DO-204AL (DO-41) does not affect electrical performance. Both are axial through-hole packages with standard lead spacing suitable for conventional PCB layouts. Physical dimensions may differ slightly, requiring verification of PCB footprint compatibility in existing designs, but electrical substitution is direct.

The 1N4006-E3/54 offers superior procurement advantages due to its active product status and significantly higher inventory availability (9002 pieces versus 845 pieces for the obsolete 1A6-AP). Selection of the 1N4006-E3/54 ensures long-term supply chain stability and eliminates obsolescence risk.

Frequently Asked Questions (FAQ)

Q: Can the 1N4006-E3/54 directly replace the 1A6-AP in existing designs?

A: Electrical substitution is direct. All electrical parameters are identical. Physical package dimensions differ between R-1 and DO-204AL (DO-41), requiring PCB footprint verification before implementation.

Q: What are the key electrical parameters that determine substitution eligibility?

A: Reverse voltage rating (800 V), average rectified current (1 A), forward voltage drop (1.1 V @ 1 A), reverse leakage current (5 µA @ 800 V), recovery speed (>500 ns), and junction temperature range (-55°C to 150°C) must match. All parameters are identical between these components.

Q: Does the package change from R-1 to DO-204AL affect circuit performance?

A: No. Both packages are axial through-hole configurations with identical electrical characteristics. Package selection affects only physical layout and mechanical mounting considerations.

Q: Are both components RoHS compliant?

A: Yes. Both the 1A6-AP and 1N4006-E3/54 are ROHS3 compliant with unlimited moisture sensitivity classification (MSL 1).

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

A: The 1A6-AP is listed as obsolete by the manufacturer. The 1N4006-E3/54 maintains active product status, ensuring continued availability and manufacturer support.

Q: What is the inventory status difference between these parts?

A: The 1A6-AP has 845 pieces in stock. The 1N4006-E3/54 has 9002 pieces in stock, providing significantly greater procurement flexibility and supply chain security.
