FR157-AP Equivalent & Substitute Parts

Part Overview

The FR157-AP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 1000 V DC reverse voltage and 1.5 A average rectified current in a DO-15 through-hole package. This component is classified as obsolete, which necessitates identification of equivalent and substitute parts for ongoing design support and procurement continuity. Active alternatives with identical or equivalent electrical specifications are available from the same manufacturer and qualified alternative sources.

Substitute Part Grouping Explanation

Substitution of the FR157-AP is determined by equivalence across the following critical parameters:

Voltage Rating: 1000 V DC reverse voltage (Vr)
Current Rating: 1.5 A average rectified current (Io)
Forward Voltage Drop: 1.3 V maximum at 1.5 A
Recovery Characteristics: Fast recovery with 500 ns reverse recovery time
Reverse Leakage: 5 µA at 1000 V
Package Compatibility: DO-15 / DO-204AC through-hole axial configuration
Temperature Range: -55°C to 150°C junction operating temperature
Compliance: RoHS3 compliance and EAR99 classification

Substitute parts must maintain all electrical specifications within the stated tolerances and support identical through-hole mounting. Package designation variations (DO-15 and DO-204AC) are mechanically and electrically equivalent for this product category.

Engineering Selection Recommendations

FR157GP-AP is the primary substitute for FR157-AP. This part is manufactured by Micro Commercial Co, the original manufacturer of the obsolete FR157-AP. The FR157GP-AP maintains active product status and carries identical electrical specifications, compliance certifications (RoHS3), and export classifications (EAR99). Direct substitution is supported without circuit modification.

FR157G is a parametric equivalent manufactured by Taiwan Semiconductor Corporation. This part meets all electrical specifications and compliance requirements of the FR157-AP. The FR157G is supplied in cut tape packaging and maintains active product status. Parametric equivalence is confirmed across voltage, current, recovery time, leakage, and temperature specifications. The FR157G supports direct functional substitution in circuit applications.

Both substitute parts are RoHS3 compliant, carry MSL rating of 1 (unlimited moisture sensitivity), and are classified under ECCN EAR99 with HTSUS code 8541.10.0080, matching the regulatory profile of the original FR157-AP.

Frequently Asked Questions (FAQ)
