Substitute Part Grouping Explanation

Substitute parts for the 1N4947GP-TP are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are:

Primary Equivalence Parameters:

• Voltage - DC Reverse (Vr) (Max): 800 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 1 A
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 5 µA @ 800 V
• Mounting Type: Through Hole
• Package / Case: DO-204AL, DO-41, Axial
• Operating Temperature - Junction: -55°C to 150°C
• RoHS Status: ROHS3 Compliant

The FR106G meets all primary equivalence parameters and is therefore classified as a parametric equivalent. Both components share identical voltage ratings, current ratings, forward voltage characteristics, and temperature operating ranges. Both are RoHS3 compliant and utilize through-hole axial mounting in DO-41/DO-204AL packages.

Engineering Selection Recommendations

1N4947GP-TP Selection Criteria: The 1N4947GP-TP is suitable for applications requiring an 800 V, 1 A general-purpose rectifier diode with fast recovery characteristics. This component is Active product status with ROHS3 compliance and REACH unaffected designation, meeting regulatory requirements for industrial and commercial applications. The 250 ns reverse recovery time supports switching applications with moderate frequency demands.

FR106G Selection Criteria: The FR106G is a parametric equivalent substitute offering identical electrical ratings and compliance certifications. The FR106G exhibits a 500 ns reverse recovery time, which remains within the fast recovery classification (≤ 500ns, > 200mA). The slightly lower capacitance (10 pF versus 15 pF) may provide marginal advantages in high-frequency switching applications. Both components are Active product status with ROHS3 compliance and REACH unaffected designation.

Substitution Basis: Both components meet all mandatory electrical parameters for 800 V, 1 A rectification. Both utilize identical through-hole DO-41/DO-204AL axial packages and operate across the same temperature range (-55°C to 150°C). Regulatory compliance is equivalent for both parts. Selection between these components is determined by availability, packaging format preference (Tape & Reel versus Cut Tape), and application-specific reverse recovery time requirements.

Frequently Asked Questions (FAQ)

Q: Can FR106G directly replace 1N4947GP-TP in existing designs?

A: Yes. Both components share identical voltage ratings (800 V), current ratings (1 A), forward voltage characteristics (1.3 V @ 1 A), and through-hole DO-41 axial package configuration. Operating temperature ranges and regulatory compliance are equivalent.

Q: What is the difference in reverse recovery time between these parts?

A: The 1N4947GP-TP has a reverse recovery time of 250 ns, while the FR106G has 500 ns. Both fall within the fast recovery classification (≤ 500ns, > 200mA). The 1N4947GP-TP offers faster switching characteristics; however, the FR106G remains suitable for applications not requiring sub-250 ns recovery performance.

Q: Are the packaging formats interchangeable?

A: Both components use through-hole DO-41/DO-204AL axial packages with identical mechanical dimensions. The primary packaging difference is supply format: 1N4947GP-TP is supplied in Tape & Reel (TR), while FR106G is supplied in Cut Tape (CT). This does not affect circuit board installation or electrical performance.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both 1N4947GP-TP and FR106G are ROHS3 compliant, REACH unaffected, and classified as Moisture Sensitivity Level 1 (Unlimited). Both carry EAR99 ECCN designation and identical HTSUS classification (8541.10.0080).

Q: Which part should be selected for high-frequency switching applications?

A: The 1N4947GP-TP, with its 250 ns reverse recovery time, is better suited for higher-frequency switching applications. The FR106G, with 500 ns recovery time, is appropriate for lower-frequency rectification and general-purpose applications where switching speed is not a critical constraint.

Q: Are there any temperature operating differences?

A: No. Both components operate across identical junction temperature ranges of -55°C to 150°C, ensuring equivalent thermal performance in all operating environments.
