Substitute Part Grouping Explanation

Substitute parts for the FR157GP-TP are identified based on strict parametric equivalence across the following criteria:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 1000 V
• Current - Average Rectified (Io): 1.5 A
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 1.5 A
• Reverse Recovery Time (trr): 500 ns
• Current - Reverse Leakage @ Vr: 5 µA @ 1000 V
• Capacitance @ Vr, F: 20 pF @ 4V, 1MHz
• Operating Temperature - Junction: -55°C to 150°C

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Package / Case: DO-204AC, DO-15, Axial

Regulatory & Compliance Parameters (Must Match):

• Technology: Standard
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

Substitutes may differ in packaging format (Tape & Reel versus Cut Tape) and manufacturer identity while maintaining identical electrical and mechanical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The FR157G manufactured by Taiwan Semiconductor Corporation is a direct parametric equivalent to the FR157GP-TP. Both components maintain identical electrical specifications, mechanical compatibility, and regulatory compliance status.

Selection Basis:

Both parts are Active product status and ROHS3 compliant with REACH Unaffected designation. The primary distinction between these components is packaging format: FR157GP-TP is supplied in Tape & Reel format, while FR157G is supplied in Cut Tape format. This difference does not affect electrical performance or mechanical fit in through-hole applications.

Component selection between FR157GP-TP and FR157G should be determined by:

• Packaging format requirements for assembly processes
• Inventory availability and lead time
• Cost considerations
• Supplier preference and qualification status

Both parts are suitable for applications requiring 1000 V, 1.5 A fast recovery rectifier diodes in DO-15 package configuration.

Frequently Asked Questions (FAQ)

Q: Can FR157G be used as a direct replacement for FR157GP-TP in existing designs?

A: Yes. The FR157G meets all electrical and mechanical parameters specified for the FR157GP-TP. Both components are rated for 1000 V reverse voltage, 1.5 A average rectified current, and feature identical forward voltage, reverse recovery time, and leakage current characteristics. Through-hole mounting compatibility is maintained.

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

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, suitable for automated pick-and-place assembly equipment. Cut Tape (CT) packaging supplies components on tape segments cut to specific lengths, suitable for manual assembly or smaller production runs. Electrical and mechanical specifications remain identical regardless of packaging format.

Q: Are there any temperature or voltage derating considerations when substituting FR157G for FR157GP-TP?

A: No. Both components share identical operating temperature range (-55°C to 150°C junction temperature) and voltage ratings (1000 V DC reverse). No derating adjustments are required when substituting between these parts.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both FR157GP-TP and FR157G are ROHS3 compliant and REACH unaffected. Regulatory compliance status is equivalent across both components.

Q: What parameters must remain constant when selecting a substitute for FR157GP-TP?

A: The following parameters must remain constant: 1000 V reverse voltage rating, 1.5 A average rectified current, 1.3 V maximum forward voltage at 1.5 A, 500 ns reverse recovery time, 5 µA reverse leakage current at 1000 V, through-hole mounting type, and DO-15 package configuration. Technology classification (Standard) and speed classification (Fast Recovery) must also be maintained.

Q: Can FR157GP-TP be substituted with parts from other manufacturers?

A: Substitution with parts from other manufacturers is possible only when all electrical parameters, mechanical specifications, and regulatory compliance requirements are met. The base product number FR157 indicates the generic device type; however, each manufacturer variant must be individually verified against the complete parameter set before substitution.
