1SS226-TP Equivalent & Substitute Parts

Part Overview

The 1SS226-TP is a general-purpose diode array manufactured by Micro Commercial Co, configured as 1 pair series connection rated for 80V DC reverse voltage and 100mA average rectified current per diode. The device is housed in a SOT-23-3 surface mount package and is supplied in Tape & Reel packaging.

The 1SS226-TP carries a product status of "Not For New Designs," indicating that while the component remains available in inventory, it is no longer recommended for new circuit development. Identifying equivalent substitute parts ensures design flexibility and supports long-term supply chain continuity for applications requiring this diode array specification.

Substitute Part Grouping Explanation

Substitute parts for the 1SS226-TP are identified based on strict parametric equivalence across the following critical specifications:

Electrical Parameters (Must Match):

• Diode Configuration: 1 Pair Series Connection
• Voltage - DC Reverse (Vr) (Max): 80V
• Current - Average Rectified (Io) (per Diode): 100mA
• Voltage - Forward (Vf) (Max) @ If: 1.2V @ 100mA
• Reverse Recovery Time (trr): 4ns
• Technology: Standard
• Speed Classification: Small Signal ≤ 200mA (Io), Any Speed

Mechanical Parameters (Must Match):

• Package / Case: TO-236-3, SC-59, SOT-23-3
• Mounting Type: Surface Mount

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts identified below meet all mandatory electrical, mechanical, and compliance criteria. Variations in reverse leakage current and maximum junction temperature represent acceptable parameter ranges within the diode array category and do not preclude substitution.

Parameter Comparison

Engineering Selection Recommendations

1SS226,LF (Toshiba Semiconductor and Storage)

The 1SS226,LF is a parametric equivalent to the 1SS226-TP with identical electrical specifications and package configuration. The primary distinction is product status: the 1SS226,LF carries an "Active" designation, indicating ongoing manufacturer support and suitability for new designs. This part is available in Cut Tape and Digi-Reel® packaging formats. Selection of the 1SS226,LF is appropriate for applications requiring direct functional replacement with active product lifecycle support.

DAN217T146 (Rohm Semiconductor)

The DAN217T146 meets all mandatory electrical and mechanical substitution criteria. This part exhibits enhanced performance characteristics: maximum junction temperature of 150°C (versus 125°C for the primary part) and lower reverse leakage current of 100nA @ 70V. The DAN217T146 carries an "Active" product status and is supplied in Cut Tape and Digi-Reel® packaging. Selection of the DAN217T146 is appropriate for applications where extended thermal operating range or reduced leakage current provides design margin.

Both substitute parts maintain full ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard surface mount assembly processes and environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1SS226,LF be used as a direct replacement for the 1SS226-TP?

A: Yes. The 1SS226,LF is a parametric equivalent with identical electrical specifications, forward voltage characteristics, reverse recovery time, and package configuration (SOT-23-3). Both parts support the same diode array configuration (1 pair series connection) at 80V and 100mA ratings. The primary difference is product status: 1SS226,LF is Active, while 1SS226-TP is Not For New Designs.

Q: What is the difference between the 1SS226,LF and DAN217T146?

A: Both parts meet the core electrical specifications for 80V, 100mA diode array operation. The DAN217T146 offers two performance enhancements: maximum junction temperature of 150°C (compared to 125°C) and lower reverse leakage current of 100nA @ 70V (compared to 500nA @ 80V). Both are housed in identical SOT-23-3 packages and are Active products.

Q: Are there packaging differences between these substitute parts?

A: Yes. The 1SS226-TP is supplied in Tape & Reel (TR) packaging. Both substitute parts—1SS226,LF and DAN217T146—are available in Cut Tape (CT) and Digi-Reel® formats. Verify packaging compatibility with your assembly process requirements before component selection.

Q: Do all three parts meet RoHS and MSL requirements?

A: Yes. The 1SS226-TP, 1SS226,LF, and DAN217T146 are all ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating. All parts are suitable for standard surface mount assembly processes without additional moisture bake-out procedures.

Q: Why is the 1SS226-TP marked "Not For New Designs"?

A: The "Not For New Designs" status indicates that while the 1SS226-TP remains available in inventory, the manufacturer no longer recommends it for new circuit development. Active substitute parts such as 1SS226,LF and DAN217T146 provide equivalent functionality with ongoing manufacturer support and are preferred for new applications.

Q: Can I use the DAN217T146 in a circuit originally designed for the 1SS226-TP?

A: Yes. The DAN217T146 meets all mandatory electrical and mechanical specifications for substitution. The enhanced maximum junction temperature (150°C) and reduced reverse leakage current represent performance improvements that do not compromise compatibility. Verify that your circuit design does not depend on the specific reverse leakage characteristics of the original part.
