Substitute Part Grouping Explanation

Substitution of the 1F6-AP rectifier diode is determined by electrical and mechanical parameter equivalence. The critical parameters that define substitutability are:

Electrical Parameters:

Voltage - DC Reverse (Vr) (Max): 800 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 @ 800 V

Mechanical Parameters:

Mounting Type: Through Hole

Engineering Selection Recommendations

The 1F6G-AP is the direct equivalent substitute for the obsolete 1F6-AP rectifier diode. Both components are manufactured by Micro Commercial Co and exhibit identical electrical and mechanical specifications across all rated parameters.

Selection Basis:

The 1F6G-AP is recommended for new designs and production applications due to its active product status and confirmed inventory availability (1098 pieces in stock). The 1F6-AP, classified as obsolete, should be replaced with the 1F6G-AP in all applications where the 800 V, 1 A fast recovery rectifier diode specification is required.

Both parts maintain ROHS3 compliance and carry identical export classification (EAR99) and tariff codes (8541.10.0080), ensuring regulatory and supply chain consistency. The MSL rating of 1 (Unlimited) for both components indicates no moisture sensitivity restrictions during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can the 1F6G-AP directly replace the 1F6-AP in existing designs?

A: Yes. The 1F6G-AP is electrically and mechanically identical to the 1F6-AP. All electrical parameters, including reverse voltage rating (800 V), forward current rating (1 A), forward voltage drop (1.3 V @ 1 A), and reverse recovery time (500 ns), are equivalent. The R-1 axial through-hole package is identical, permitting direct substitution without circuit modification or PCB redesign.

Q: What is the primary reason for substituting the 1F6-AP?

A: The 1F6-AP is classified as obsolete, indicating discontinued manufacturing and limited inventory availability. The 1F6G-AP is an active product with confirmed stock levels, ensuring reliable supply for current and future production requirements.

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

A: No. Both the 1F6-AP and 1F6G-AP maintain identical ROHS3 compliance status, EAR99 export classification, and HTSUS tariff code (8541.10.0080). Moisture sensitivity level (MSL 1) is also identical for both components.

Q: What are the critical electrical parameters that define substitutability for this rectifier diode?

A: Substitutability is determined by the following electrical parameters: DC reverse voltage rating (800 V), average rectified current (1 A), forward voltage drop (1.3 V @ 1 A), reverse recovery time (500 ns), and reverse leakage current (5 µA @ 800 V). The 1F6G-AP matches all these specifications.

Q: Is the R-1 axial package identical between both parts?

A: Yes. Both the 1F6-AP and 1F6G-AP use the R-1 axial through-hole package. No mechanical modifications or board layout changes are required for substitution.

Q: What is the operating temperature range for both components?

A: Both the 1F6-AP and 1F6G-AP operate across a junction temperature range of -55°C to 150°C, providing identical thermal performance specifications.
