S5GL-TP Equivalent & Substitute Parts Reference

Part Overview

The S5GL-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 400 V DC reverse voltage and 5 A average rectified current in a Surface Mount SMC (DO-214AB) package. This component is classified as "Not For New Designs," indicating it has reached end-of-life status. Identifying equivalent and substitute parts is necessary for legacy system maintenance, repair operations, and design transitions to active product alternatives that meet identical or superior electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the S5GL-TP is determined by the following critical parameters:

Primary Matching Criteria:

• Voltage - DC Reverse (Vr) (Max): 400 V minimum
• Current - Average Rectified (Io): 5 A minimum
• Package / Case: DO-214AB, SMC (Surface Mount)
• Mounting Type: Surface Mount

Secondary Compatibility Factors:

• Voltage - Forward (Vf) (Max) @ If: ≤ 1.2 V @ 5 A
• Current - Reverse Leakage @ Vr: ≤ 10 µA @ 400 V
• Operating Temperature - Junction: Minimum -55°C to maximum 150°C
• RoHS3 Compliance and MSL Level 1 rating

Substitute parts are grouped into two categories:

Category A - Full Electrical Equivalents (5 A Rating): Parts meeting all primary criteria with identical or superior forward voltage and reverse leakage characteristics. These include CGRC504-G, S5GC-13-F, and UFS540J/TR13.

Category B - Reduced Current Rating (3 A Rating): The STTH3R04S operates at 3 A average rectified current, which is below the 5 A specification of the S5GL-TP. This part is suitable only for applications where the actual circuit current demand does not exceed 3 A, despite the original design specification.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred):

CGRC504-G and S5GC-13-F are the primary substitutes for the S5GL-TP. Both parts are Active products with identical voltage and current ratings (400 V, 5 A), matching package specifications (DO-214AB, SMC), and RoHS3 compliance. CGRC504-G offers a marginal improvement in forward voltage (1.15 V vs. 1.2 V), while S5GC-13-F provides an extended lower operating temperature range (-65°C vs. -55°C). Both are suitable for direct circuit substitution without design modification.

For Applications Requiring Enhanced Recovery Characteristics:

UFS540J/TR13 provides identical electrical ratings to the S5GL-TP (400 V, 5 A, 1.2 V forward voltage) with fast recovery characteristics (≤ 500 ns) and an extended upper operating temperature range (175°C). However, this part carries RoHS non-compliant status, which may restrict use in regulated applications. UFS540J/TR13 is suitable only where RoHS compliance is not a requirement.

For Current-Limited Applications:

STTH3R04S is suitable only for applications where the actual circuit current does not exceed 3 A. This part offers superior reverse leakage characteristics (5 µA vs. 10 µA), fast recovery performance, and the highest operating temperature rating (175°C). Use of STTH3R04S in circuits designed for 5 A operation will result in thermal stress and potential component failure.

Compliance Considerations:

All substitute parts except UFS540J/TR13 maintain RoHS3 compliance. For new designs or applications subject to regulatory compliance requirements, CGRC504-G or S5GC-13-F are the recommended selections.

Frequently Asked Questions (FAQ)

Q: Can the S5GL-TP be directly replaced with CGRC504-G or S5GC-13-F?

A: Yes. Both CGRC504-G and S5GC-13-F meet all primary electrical and mechanical specifications of the S5GL-TP. They share identical voltage ratings (400 V), current ratings (5 A), package type (DO-214AB, SMC), and mounting configuration (Surface Mount). No circuit modification is required for substitution.

Q: What is the difference between the S5GC-13-F and CGRC504-G?

A: Both parts are electrically equivalent with 400 V, 5 A ratings and 1.15 V forward voltage. The primary differences are: S5GC-13-F has an extended lower operating temperature range (-65°C to 150°C vs. 150°C maximum for CGRC504-G), and S5GC-13-F includes specified junction capacitance (40 pF @ 4V, 1MHz). CGRC504-G does not specify capacitance. Selection depends on whether the lower temperature range or capacitance specification is required for the application.

Q: Why is STTH3R04S listed as a substitute if it has a lower current rating?

A: STTH3R04S is listed as a substitute option for applications where the actual circuit current demand does not exceed 3 A. While the S5GL-TP is rated for 5 A, many circuits operate at lower current levels. STTH3R04S offers superior reverse leakage (5 µA vs. 10 µA) and fast recovery characteristics. However, it must not be used in circuits designed for 5 A operation.

Q: Is UFS540J/TR13 suitable for new designs?

A: UFS540J/TR13 is an Active product with identical electrical ratings to the S5GL-TP and offers fast recovery performance. However, it carries RoHS non-compliant status. For new designs subject to RoHS compliance requirements, CGRC504-G or S5GC-13-F are the appropriate selections. UFS540J/TR13 is suitable only for applications where RoHS compliance is not mandated.

Q: What packaging formats are available for these substitute parts?

A: CGRC504-G, S5GC-13-F, and UFS540J/TR13 are supplied in Tape & Reel (TR) packaging, matching the S5GL-TP format. STTH3R04S is supplied in Cut Tape (CT) and Digi-Reel® format. For high-volume production requiring reel packaging, STTH3R04S may require alternative sourcing or packaging conversion.

Q: Can forward voltage differences affect circuit performance?

A: Forward voltage differences between substitute parts are minimal (1.15 V to 1.5 V range). In most rectifier applications, these variations produce negligible effects on circuit performance. However, in precision analog circuits or applications with tight voltage regulation requirements, forward voltage differences should be evaluated against circuit tolerance specifications.

Q: What does "Standard Recovery" versus "Fast Recovery" mean for these diodes?

A: Recovery speed refers to the time required for the diode to transition from conducting to blocking state. Standard Recovery (>500 ns) is suitable for general-purpose rectification and power supply applications. Fast Recovery (≤ 500 ns) reduces switching losses and is preferred in high-frequency switching applications. The S5GL-TP uses Standard Recovery; substitutes with Fast Recovery (UFS540J/TR13, STTH3R04S) are compatible but offer performance advantages in switching circuits.

Q: Are all substitute parts RoHS3 compliant?

A: CGRC504-G, S5GC-13-F, and STTH3R04S are RoHS3 compliant. UFS540J/TR13 is RoHS non-compliant. For applications requiring RoHS compliance certification, use only CGRC504-G, S5GC-13-F, or STTH3R04S.
