Substitute Part Grouping Explanation

Substitute parts for the 1SS226,LF diode array are qualified based on the following critical parameters that determine functional interchangeability:

Electrical Equivalence Criteria:

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

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount
• Package / Case: TO-236-3, SC-59, SOT-23-3
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Compliance Criteria:

• RoHS3 Compliant
• REACH Unaffected
• ECCN: EAR99

Parts meeting all electrical and mechanical criteria are classified as parametric equivalents and direct substitutes. Variations in packaging format (Cut Tape vs. Tape & Reel) and product status do not affect electrical interchangeability.

Engineering Selection Recommendations

Primary Selection: 1SS226,LF (Toshiba Semiconductor and Storage)

The 1SS226,LF maintains Active product status and is the baseline reference part. This part is suitable for all new designs and ongoing production applications requiring a general-purpose diode array with 80 V reverse voltage rating and 100 mA current capacity in SOT-23-3 surface mount packaging.

Secondary Selection: DAN217T146 (Rohm Semiconductor)

The DAN217T146 is a parametric equivalent with Active product status. This part meets all electrical specifications and mechanical compatibility requirements. The DAN217T146 offers an enhanced maximum junction temperature rating of 150°C compared to 125°C for the 1SS226,LF, and lower reverse leakage current (100 nA @ 70 V). The DAN217T146 is suitable for new designs and applications requiring extended thermal performance within the same package footprint.

Tertiary Selection: 1SS226-TP (Micro Commercial Co)

The 1SS226-TP is a parametric equivalent with Not For New Designs product status. This part meets all electrical specifications and mechanical compatibility requirements but is not recommended for new design implementations. The 1SS226-TP may be used for legacy system maintenance, repair, or replacement of existing assemblies where the original part is unavailable. Packaging is supplied in Tape & Reel format.

All three parts are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS coding (8541.10.0070).

Frequently Asked Questions (FAQ)

Q: Can the 1SS226-TP substitute for the 1SS226,LF in new designs?

A: The 1SS226-TP is electrically and mechanically equivalent to the 1SS226,LF; however, it carries Not For New Designs product status. For new design implementations, use the 1SS226,LF or DAN217T146.

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

A: Both parts are parametric equivalents with identical electrical performance at rated conditions. The DAN217T146 offers a higher maximum junction temperature (150°C vs. 125°C) and lower reverse leakage current (100 nA @ 70 V vs. 500 nA @ 80 V). Both are suitable for new designs.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the TO-236-3 (SC-59, SOT-23-3) package with identical pinout and footprint. Surface mount assembly compatibility is maintained across all substitutes.

Q: Does packaging format affect electrical performance?

A: No. The packaging format (Cut Tape & Digi-Reel® vs. Tape & Reel) affects only supply and handling logistics. Electrical and mechanical specifications remain identical regardless of packaging format.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The 1SS226,LF, 1SS226-TP, and DAN217T146 are all RoHS3 compliant with Moisture Sensitivity Level 1 (Unlimited) and REACH unaffected status.

Q: Can I use DAN217T146 in place of 1SS226,LF for existing production?

A: Yes. The DAN217T146 is a direct parametric equivalent with superior thermal performance. No circuit modifications are required for substitution in existing designs.

Q: What is the reverse recovery time specification used for?

A: Reverse recovery time (trr) of 4 ns indicates the speed classification of the diode. All three parts are classified as small signal diodes with identical recovery characteristics, suitable for applications requiring fast switching response.
