Substitute Part Grouping Explanation

Substitution of the obsolete 1F2-AP is determined by electrical and mechanical parameter equivalence. The primary substitution criteria are:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 1 A
• Reverse Recovery Time (trr): 150 ns
• Current - Reverse Leakage @ Vr: 5 µA @ 100 V
• Capacitance @ Vr, F: 12 pF @ 4V, 1MHz
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Package / Case: R-1, Axial
• Operating Temperature - Junction: -55°C to 150°C
• Technology: Standard

The 1F2G-AP meets all specified electrical and mechanical parameters and is classified as an active product, providing direct functional equivalence for circuit replacement and new procurement applications.

Parameter Comparison

Engineering Selection Recommendations

The 1F2G-AP is the direct active equivalent for the obsolete 1F2-AP. All electrical parameters, mechanical specifications, and compliance certifications are identical between the two parts. The 1F2G-AP maintains ROHS3 compliance and carries identical export classification (EAR99) and tariff codes (HTSUS 8541.10.0080).

Selection of the 1F2G-AP for replacement applications is based on:

• Complete electrical parameter equivalence across all specified ratings
• Identical mechanical package and mounting configuration
• Active product status ensuring continued availability and supply chain support
• Equivalent regulatory compliance and environmental certifications
• Identical thermal operating range and performance characteristics

The 1F2G-AP is suitable for direct substitution in all applications previously designed for the 1F2-AP without circuit modification or re-qualification.
