Substitute Part Grouping Explanation

Substitute parts for the FR155GP-TP are identified based on strict equivalence across the following critical parameters:

Voltage Rating: 600 V DC reverse voltage maximum
Current Rating: 1.5 A average rectified current
Forward Voltage Drop: 1.3 V maximum at 1.5 A
Reverse Recovery Time: 250 ns
Reverse Leakage Current: 5 µA at 600 V
Junction Capacitance: 20 pF at 4 V, 1 MHz
Operating Temperature Range: -55°C to 150°C
Package Type: Through-hole axial configuration (DO-15/DO-204AC)
Technology Classification: Standard rectifier diode
Compliance: RoHS3 compliant, REACH unaffected

Substitute parts must maintain identical electrical performance across all specified parameters and support the same through-hole mounting methodology. Packaging format variations (Tape & Reel versus Cut Tape) do not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can FR155GH replace FR155GP-TP in existing circuit designs?

A: Yes. The FR155GH is a parametric equivalent with identical electrical specifications across all critical parameters: 600 V reverse voltage, 1.5 A current rating, 1.3 V forward voltage drop, 250 ns reverse recovery time, and -55°C to 150°C operating temperature range. Both parts use the same through-hole DO-15 package configuration and are mechanically compatible.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, suitable for automated assembly processes. Cut Tape packaging supplies the same components on shorter tape segments, typically for manual assembly or lower-volume applications. Both packaging formats contain identical components with no electrical or mechanical differences.

Q: Are both parts RoHS3 compliant?

A: Yes. Both FR155GP-TP and FR155GH are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What does AEC-Q101 qualification mean for the FR155GH?

A: AEC-Q101 is an automotive industry qualification standard. The FR155GH meets this standard, indicating suitability for automotive applications. The FR155GP-TP does not carry this designation but remains suitable for general-purpose applications.

Q: Are the reverse recovery times identical?

A: Yes. Both parts specify 250 ns reverse recovery time, confirming equivalent fast recovery diode performance.

Q: Can these parts be used interchangeably in production?

A: Yes, provided the selected packaging format (Tape & Reel or Cut Tape) aligns with assembly process requirements. Electrical and mechanical specifications are identical, enabling direct substitution.
