DAP222T1 Equivalent & Substitute Parts

Part Overview

The DAP222T1 is a general-purpose diode array featuring a 1 Pair Common Anode configuration rated for 80 V DC reverse voltage and 100 mA average rectified current per diode. This component is packaged in SC-75 (SOT-416) surface mount format and is classified as obsolete. The DAP222T1 is manufactured by onsemi and is no longer in active production, necessitating identification of equivalent and substitute components for ongoing design requirements and board-level replacements.

Substitute Part Grouping Explanation

Substitute parts for the DAP222T1 are classified into two categories based on electrical and mechanical compatibility:

Direct Equivalent (Packaging Variant): DAP222T1G represents the same base product (DAP222) with identical electrical specifications but supplied in Tape & Reel packaging. This part maintains all critical parameters: 80 V reverse voltage, 100 mA average rectified current, 1.2 V forward voltage at 100 mA, 10 ns reverse recovery time, and SC-75 (SOT-416) package format. The primary distinction is product status (Active vs. Obsolete) and RoHS compliance level.

Parametric Equivalent (Enhanced Ratings): DAP222G shares the same base product number and electrical characteristics as DAP222T1, with identical voltage, current, and thermal specifications. This part is supplied in Tape & Reel packaging and maintains SC-75 (SOT-416) package compatibility.

Similar Substitute (Higher Performance): BAW56M,315 is a diode array from Nexperia USA Inc. with enhanced electrical ratings: 90 V reverse voltage (vs. 80 V), 150 mA average rectified current (vs. 100 mA), and improved reverse recovery time of 4 ns (vs. 10 ns). This part uses SC-101 (SOT-883) package format, which differs from the original SC-75 (SOT-416). The BAW56M,315 includes automotive qualification (AEC-Q101) and is suitable for applications requiring higher performance margins.

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance): DAP222T1G is the primary substitute when maintaining exact electrical specifications is required. This part is electrically identical to DAP222T1 with all parameters matching precisely: 80 V reverse voltage, 100 mA average rectified current, 1.2 V forward voltage, and 10 ns reverse recovery time. DAP222T1G is in Active product status with ROHS3 compliance and significantly higher inventory availability (62,300 units). The SC-75 (SOT-416) package format ensures direct PCB compatibility without layout modifications.

For Parametric Equivalence (Same Base Product): DAP222G provides identical electrical specifications to DAP222T1 and is also based on the DAP222 product line. This part maintains all critical electrical parameters and SC-75 (SOT-416) package compatibility. DAP222G is in Active product status with ROHS3 compliance. Inventory availability is lower (1,510 units) compared to DAP222T1G.

For Enhanced Performance Applications: BAW56M,315 is suitable for applications requiring higher performance margins or automotive-grade qualification. This part provides 90 V reverse voltage (12.5% higher than DAP222T1), 150 mA average rectified current (50% higher), and superior reverse recovery time of 4 ns (60% faster). The BAW56M,315 includes AEC-Q101 automotive qualification. However, the SC-101 (SOT-883) package format differs from the original SC-75 (SOT-416), requiring PCB layout modifications and footprint changes. Forward voltage is slightly higher at 1.25 V @ 150 mA, and reverse leakage current is higher at 500 nA @ 80 V.

Frequently Asked Questions (FAQ)

Q: Can DAP222T1G be used as a direct replacement for DAP222T1?

A: Yes. DAP222T1G is electrically identical to DAP222T1 with matching specifications across all critical parameters: 80 V reverse voltage, 100 mA average rectified current, 1.2 V forward voltage at 100 mA, 10 ns reverse recovery time, and identical SC-75 (SOT-416) package format. The primary differences are product status (Active vs. Obsolete), RoHS compliance level (ROHS3 vs. non-compliant), and packaging format (Tape & Reel vs. Bulk). PCB footprint and electrical performance are identical.

Q: What is the difference between DAP222T1G and DAP222G?

A: Both parts are electrically identical and based on the onsemi DAP222 product line with matching specifications. Both are in Active product status, ROHS3 compliant, and use SC-75 (SOT-416) packaging. The primary distinction is inventory availability: DAP222T1G has 62,300 units in stock, while DAP222G has 1,510 units. Both are supplied in Tape & Reel packaging format.

Q: Can BAW56M,315 replace DAP222T1 in all applications?

A: BAW56M,315 is not a direct replacement due to package format differences. The BAW56M,315 uses SC-101 (SOT-883) packaging, while DAP222T1 uses SC-75 (SOT-416), requiring PCB layout and footprint modifications. However, BAW56M,315 is electrically compatible for applications where higher performance margins are acceptable: 90 V reverse voltage (vs. 80 V), 150 mA average rectified current (vs. 100 mA), and 4 ns reverse recovery time (vs. 10 ns). Forward voltage is slightly higher at 1.25 V @ 150 mA, and reverse leakage is higher at 500 nA @ 80 V. BAW56M,315 includes automotive qualification (AEC-Q101).

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

A: Substitution compatibility is determined by: (1) Diode Configuration (1 Pair Common Anode required), (2) Voltage - DC Reverse (Vr) rating (minimum 80 V), (3) Current - Average Rectified (Io) rating (minimum 100 mA per diode), (4) Package / Case format (SC-75, SOT-416 for direct replacement), and (5) Mounting Type (Surface Mount). Forward voltage, reverse recovery time, and reverse leakage current are secondary parameters that affect performance but do not prevent substitution if the primary parameters are met or exceeded.

Q: Is RoHS compliance a factor in selecting a substitute?

A: RoHS compliance status is a regulatory and procurement consideration rather than an electrical compatibility factor. DAP222T1 is RoHS non-compliant, while DAP222T1G, DAP222G, and BAW56M,315 are all ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, ROHS3-compliant parts (DAP222T1G, DAP222G, or BAW56M,315) are required.

Q: What is the significance of the SC-75 (SOT-416) vs. SC-101 (SOT-883) package difference?

A: SC-75 (SOT-416) and SC-101 (SOT-883) are different surface mount package formats with different physical dimensions and PCB footprints. DAP222T1, DAP222T1G, and DAP222G all use SC-75 (SOT-416), allowing direct PCB compatibility. BAW56M,315 uses SC-101 (SOT-883), which requires different PCB footprint design and cannot be used in existing SC-75 (SOT-416) layouts without modification.

Q: Why is DAP222T1 classified as obsolete?

A: DAP222T1 is classified as obsolete, indicating it is no longer in active production by onsemi. Active alternatives such as DAP222T1G and DAP222G are available with identical or equivalent electrical specifications. For new designs or ongoing production, active parts are recommended to ensure long-term supply availability.
