S5DL-TP Equivalent & Substitute Parts

Part Overview

The S5DL-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 200 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 ongoing maintenance, repair, and legacy system support where the original part is no longer readily available or when design flexibility permits component selection from active product lines.

Substitute Part Grouping Explanation

Substitution of the S5DL-TP is determined by the following critical parameters:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): 200 V minimum
Current - Average Rectified (Io): 5 A minimum
Package / Case: DO-214AB, SMC (physical and electrical compatibility)
Mounting Type: Surface Mount
RoHS Status: ROHS3 Compliant

Secondary Compatibility Factors:

Voltage - Forward (Vf) (Max) @ If: Must not exceed application requirements
Current - Reverse Leakage @ Vr: Lower values indicate superior performance
Operating Temperature - Junction: Must accommodate application thermal environment
Speed: Recovery characteristics must match circuit switching requirements

Substitute parts are grouped into two categories:

Category A - Full Electrical Equivalents (5 A Rating): Parts meeting or exceeding all primary criteria with identical 5 A current rating. These provide direct functional replacement with no circuit redesign required.

Category B - Reduced Current Equivalents (3 A Rating): Parts with 200 V voltage rating but reduced to 3 A current rating. These are suitable only for applications where the actual circuit current demand does not exceed 3 A, regardless of the original 5 A design specification.

Engineering Selection Recommendations

For Direct Replacement (5 A Current Rating Required):

CGRC503-G (Comchip Technology) and S5DC-13-F (Diodes Incorporated) are the primary substitutes for the S5DL-TP. Both parts maintain the 5 A current rating, 200 V voltage specification, and DO-214AB SMC package. Both are classified as Active products, ensuring long-term availability and supply chain stability. CGRC503-G exhibits marginally lower forward voltage (1.15 V vs. 1.2 V), while S5DC-13-F provides an extended operating temperature range (-65°C to 150°C) compared to the original part (-55°C to 150°C). Both parts are ROHS3 compliant and suitable for legacy system maintenance.

For Reduced Current Applications (3 A Maximum):

STTH302S and STTH3R02S (both STMicroelectronics) are substitutes only when circuit analysis confirms that actual operating current does not exceed 3 A. These parts offer superior performance characteristics including fast recovery time (≤500 ns vs. >500 ns), lower reverse leakage current (3 µA vs. 10 µA), and higher maximum junction temperature (175°C vs. 150°C). These parts are Active products with established supply availability. Selection between STTH302S and STTH3R02S depends on forward voltage requirements: STTH302S at 950 mV @ 3 A or STTH3R02S at 1 V @ 3 A.

Compliance and Availability:

All substitute parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. All substitute parts are currently Active products, providing superior long-term availability compared to the Not For New Designs status of the S5DL-TP.

Frequently Asked Questions (FAQ)

Q: Can STTH302S or STTH3R02S be used as direct replacements for S5DL-TP?

A: Only if circuit analysis confirms that maximum operating current does not exceed 3 A. These parts are rated for 3 A average rectified current, compared to the S5DL-TP's 5 A rating. Using a 3 A part in a circuit designed for 5 A operation will result in component failure or circuit malfunction.

Q: What is the difference between CGRC503-G and S5DC-13-F?

A: Both parts are full 5 A equivalents with identical voltage and current ratings. CGRC503-G is supplied in Tape & Reel packaging, while S5DC-13-F is supplied in Cut Tape & Digi-Reel format. CGRC503-G specifies a maximum junction temperature of 150°C, while S5DC-13-F specifies an operating range of -65°C to 150°C, providing a lower temperature bound. Forward voltage is identical at 1.15 V @ 5 A for both parts.

Q: Are all substitute parts in the same physical package?

A: Yes. All substitute parts use the DO-214AB SMC package, which is physically and electrically identical to the S5DL-TP package. Surface mount assembly equipment and PCB footprints require no modification.

Q: Why do STTH302S and STTH3R02S have lower reverse leakage current?

A: These parts employ fast recovery technology, which inherently produces lower reverse leakage (3 µA vs. 10 µA). This is a characteristic of the technology, not a design trade-off. However, this advantage is only realized if the 3 A current rating is sufficient for the application.

Q: What is the significance of "Fast Recovery" vs. "Standard Recovery" speed?

A: Recovery speed determines how quickly the diode transitions from conducting to blocking state. Fast recovery (≤500 ns) is beneficial in high-frequency switching applications and reduces switching losses. Standard recovery (>500 ns) is adequate for lower-frequency rectification. The S5DL-TP uses standard recovery; STTH302S and STTH3R02S use fast recovery. This difference is not a limitation for standard rectification applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts are ROHS3 compliant, matching the compliance status of the S5DL-TP. All parts are also REACH unaffected.

Q: Which substitute part should be selected for new designs?

A: S5DC-13-F (Diodes Incorporated) is recommended for new designs requiring 5 A operation. It is an Active product with established supply chain presence, extended operating temperature range, and proven reliability. CGRC503-G is an alternative if Comchip Technology is the preferred supplier.

Q: Can forward voltage differences affect circuit performance?

A: Forward voltage differences between 950 mV and 1.2 V are typically negligible in rectification circuits where the diode voltage drop is small relative to the total circuit voltage. However, in precision applications or circuits with tight voltage margins, forward voltage should be verified against circuit requirements.
