Electrical Parameters (Critical for Substitution):

• Voltage - DC Reverse (Vr) (Max): 1000 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 1 A
• Reverse Recovery Time (trr): 500 ns
• Current - Reverse Leakage @ Vr: 5 µA @ 1000 V
• Capacitance @ Vr, F: 12 pF @ 4V, 1MHz
• Technology: Standard
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Parameters (Critical for Substitution):

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

The 1F7G-AP meets all specified electrical and mechanical parameters and is classified as an active product, providing direct substitution capability.

Parameter Comparison

Engineering Selection Recommendations

The 1F7G-AP is a direct substitute for the obsolete 1F7-AP. Both components are manufactured by Micro Commercial Co and share identical electrical and mechanical specifications across all rated parameters. The 1F7G-AP holds active product status, ensuring ongoing availability and manufacturer support, whereas the 1F7-AP is classified as obsolete.

Both parts maintain ROHS3 compliance and carry identical export classification (EAR99) and tariff codes (HTSUS 8541.10.0080). The moisture sensitivity level is equivalent at MSL 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

For applications currently specified with the 1F7-AP, the 1F7G-AP provides complete functional and mechanical compatibility without design modification. The active status of the 1F7G-AP supports long-term procurement continuity and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the 1F7G-AP be used as a direct replacement for the 1F7-AP in existing designs?

A: Yes. The 1F7G-AP is a direct substitute. All electrical parameters (voltage rating, current rating, forward voltage, reverse recovery time, leakage current, and capacitance) are identical. The mechanical package (R-1 axial through-hole) and operating temperature range (-55°C to 150°C) are also identical.

Q: What is the primary reason for substituting the 1F7-AP?

A: The 1F7-AP is classified as obsolete. The 1F7G-AP is the active equivalent from the same manufacturer, providing identical performance with assured long-term availability.

Q: Are there any compliance or certification differences between the two parts?

A: No. Both parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and share identical export classification (EAR99) and tariff codes (HTSUS 8541.10.0080).

Q: Will the 1F7G-AP require any PCB layout or assembly process changes?

A: No. The 1F7G-AP uses the same R-1 axial through-hole package as the 1F7-AP. No modifications to PCB footprints, lead spacing, or assembly procedures are required.

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

A: Substitution is based on matching: DC reverse voltage (1000 V), average rectified current (1 A), forward voltage (1.3 V @ 1 A), reverse recovery time (500 ns), reverse leakage current (5 µA @ 1000 V), and junction capacitance (12 pF @ 4V, 1MHz). The 1F7G-AP matches all these parameters.

Q: Is the 1F7G-AP available in the same packaging format?

A: Yes. The 1F7G-AP is supplied in the R-1 axial through-hole package, identical to the 1F7-AP. No package conversion or adapter components are necessary.
