FR157GP-AP Equivalent & Substitute Parts

Part Overview

The FR157GP-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 through-hole DO-15 package. This diode is designed for standard rectification applications requiring fast recovery characteristics. The part is Active in product status and fully compliant with RoHS3 and REACH regulations.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter set. Alternative sources may be required due to inventory availability, supply chain considerations, or procurement preferences while maintaining identical functional performance.

Electrical Parameters:

• Voltage - DC Reverse (Vr) (Max): 1000 V
• Current - Average Rectified (Io): 1.5 A
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 1.5 A
• Reverse Recovery Time (trr): 500 ns
• Current - Reverse Leakage @ Vr: 5 µA @ 1000 V
• Capacitance @ Vr, F: 20 pF @ 4V, 1MHz
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Parameters:

• Mounting Type: Through Hole
• Package / Case: DO-204AC, DO-15, Axial
• Operating Temperature - Junction: -55°C to 150°C
• Technology: Standard

Substitute parts must match all listed parameters without deviation. The FR157G from Taiwan Semiconductor Corporation meets all specified criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the FR157GP-AP and FR157G are Active products with full RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

The FR157G from Taiwan Semiconductor Corporation is a direct parametric equivalent to the FR157GP-AP. All electrical characteristics, mechanical specifications, temperature ratings, and compliance certifications are identical. The primary difference is packaging format: FR157GP-AP is supplied in standard packaging, while FR157G is supplied in Cut Tape (CT) format.

Selection between these parts should be based on:

1. Packaging Requirements: FR157G in Cut Tape format is suitable for automated assembly processes. FR157GP-AP standard packaging may be preferred for manual assembly or specific procurement workflows.

2. Inventory Availability: FR157G has significantly higher inventory (15,800 pcs) compared to FR157GP-AP (766 pcs), which may influence lead time and supply chain continuity.

3. Regulatory Compliance: Both parts satisfy RoHS3 and REACH requirements without exception.

4. Functional Equivalence: Complete electrical and thermal equivalence permits direct substitution in circuit designs without performance degradation.
