Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1SS361CT(TPL3) are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

Primary Matching Parameters:

• Diode configuration: 1 pair common cathode
• Voltage - DC reverse (Vr) (Max): 80 V
• Current - average rectified (Io) (per diode): 100 mA
• Voltage - forward (Vf) (Max) @ If: 1.2 V @ 100 mA
• Speed classification: Small signal ≤ 200mA (Io), any speed
• Operating temperature - junction (Max): 150°C
• Mounting type: Surface mount
• RoHS compliance: Active

Secondary Considerations:

• Package form factor compatibility
• Supplier device package designation
• Product status (active)
• Regulatory compliance certifications

The DAN202KT146 manufactured by Rohm Semiconductor satisfies all primary electrical parameters and maintains active product status with appropriate regulatory compliance. Package differences (SC-101, SOT-883 versus TO-236-3, SC-59, SOT-23-3) represent alternative surface mount form factors suitable for different PCB layout requirements.

Parameter Comparison

Engineering Selection Recommendations

The DAN202KT146 is a functionally equivalent substitute for the 1SS361CT(TPL3) based on matching electrical specifications and regulatory compliance status. Both components are active products with RoHS compliance and unlimited moisture sensitivity level (MSL 1).

Selection Basis:

1. Electrical Equivalence: All critical electrical parameters match exactly: 80 V reverse voltage rating, 100 mA average rectified current per diode, 1.2 V forward voltage at 100 mA, and 150°C maximum junction temperature.

2. Configuration Match: Both devices feature identical 1 pair common cathode diode array configuration, ensuring pin-level functional compatibility within the circuit topology.

3. Regulatory Compliance: Both components maintain active product status and satisfy RoHS requirements. The DAN202KT146 carries ROHS3 compliance and REACH unaffected status, meeting current regulatory standards.

4. Packaging Consideration: The DAN202KT146 uses TO-236-3, SC-59, SOT-23-3 package form factors, which differ from the SC-101, SOT-883 package of the 1SS361CT(TPL3). PCB layout and footprint modifications are required for substitution.

5. Secondary Parameter Differences: The DAN202KT146 exhibits a higher reverse recovery time (4 ns versus 1.6 ns) and lower reverse leakage current (100 nA @ 70 V versus 500 nA @ 80 V). These differences do not affect substitution validity for general-purpose applications within the specified electrical operating range.

Frequently Asked Questions (FAQ)

Q: Can the DAN202KT146 directly replace the 1SS361CT(TPL3) without circuit modification?

A: The DAN202KT146 is electrically equivalent and functionally compatible. However, the package form factor differs (TO-236-3, SC-59, SOT-23-3 versus SC-101, SOT-883), requiring PCB footprint and layout modifications. Pin configuration and electrical function remain compatible.

Q: What are the critical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: diode configuration (1 pair common cathode), voltage rating (80 V DC reverse), current rating (100 mA average rectified per diode), forward voltage (1.2 V @ 100 mA), speed classification (small signal), and maximum junction temperature (150°C). All these parameters match between the 1SS361CT(TPL3) and DAN202KT146.

Q: Does the difference in reverse recovery time affect circuit performance?

A: The DAN202KT146 has a reverse recovery time of 4 ns compared to 1.6 ns for the 1SS361CT(TPL3). This parameter is provided for reference. Selection should be based on the application's specific switching speed requirements and the electrical specifications provided in the datasheet.

Q: Are both components RoHS compliant?

A: Yes. The 1SS361CT(TPL3) is RoHS compliant. The DAN202KT146 is ROHS3 compliant and REACH unaffected, meeting current regulatory standards for both components.

Q: What is the moisture sensitivity level for both parts?

A: Both the 1SS361CT(TPL3) and DAN202KT146 have MSL 1 (unlimited), indicating no moisture sensitivity restrictions during storage and handling.

Q: How do the reverse leakage current specifications compare?

A: The 1SS361CT(TPL3) specifies 500 nA @ 80 V, while the DAN202KT146 specifies 100 nA @ 70 V. These are measured at different voltage conditions. Both values are within acceptable ranges for general-purpose diode applications.

Q: What inventory availability exists for these parts?

A: The 1SS361CT(TPL3) has 2200 pieces in stock. The DAN202KT146 has 205245 pieces in stock, providing significantly higher availability for supply chain continuity.
