DAP222 Equivalent & Substitute Parts

Part Overview

The DAP222 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. The device is packaged in SC-75 (SOT-416) surface mount format and is classified as obsolete. Due to its obsolete status, equivalent and substitute parts are necessary for ongoing design support, production continuity, and component sourcing in applications requiring diode array functionality with comparable electrical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DAP222 are classified into two categories based on electrical and mechanical compatibility:

Direct Equivalents (Identical Electrical and Mechanical Parameters): Direct equivalents maintain all critical electrical specifications including 80 V reverse voltage rating, 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. These parts differ only in product status (active versus obsolete) and packaging configuration (bulk versus tape & reel).

Similar Substitutes (Compatible Configuration, Enhanced Ratings): Similar substitutes maintain the 1 Pair Common Anode diode configuration and small signal speed classification but feature enhanced voltage and current ratings. These parts operate within the same technology class and mounting type but utilize different package formats (SOT-883 or SOT-523). Enhanced ratings provide design margin in applications where the DAP222 specifications are met but higher performance headroom is beneficial.

Key parameters determining substitution eligibility:

• Diode Configuration: 1 Pair Common Anode (required)
• Mounting Type: Surface Mount (required)
• Technology: Standard (required)
• Speed Classification: Small Signal ≤ 200 mA (required)
• Voltage - DC Reverse (Vr): Minimum 80 V
• Current - Average Rectified (Io): Minimum 100 mA per diode
• Operating Temperature - Junction: Minimum 150°C

Engineering Selection Recommendations

Direct Equivalent Selection (DAP222G, DAP222T1G):

DAP222G and DAP222T1G are direct electrical and mechanical equivalents to the DAP222. Both parts maintain identical electrical 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 SC-75 (SOT-416) package format. Both parts carry Active product status and ROHS3 compliance, providing long-term availability and regulatory alignment. DAP222T1G offers higher inventory availability (62,300 pieces) compared to DAP222G (1,510 pieces), making it the preferred choice for production applications requiring sustained component supply.

Similar Substitute Selection (BAW56M,315, BAW56TB_R1_00001):

BAW56M,315 and BAW56TB_R1_00001 are similar substitutes suitable for applications where the DAP222 electrical specifications are satisfied but enhanced performance margins are acceptable. BAW56M,315 provides 90 V reverse voltage and 150 mA average rectified current with improved 4 ns reverse recovery time in SOT-883 package format. BAW56TB_R1_00001 provides 150 mA average rectified current with 4 ns reverse recovery time in SOT-523 package format, though its 75 V reverse voltage rating is below the DAP222 specification and requires circuit-level voltage margin verification. Both similar substitutes carry Active product status and ROHS3 compliance. Package format changes require PCB layout modification and mechanical validation.

Frequently Asked Questions (FAQ)

Q: Can DAP222G and DAP222T1G be used interchangeably with the DAP222?

A: Yes. DAP222G and DAP222T1G are direct electrical and mechanical equivalents. All critical electrical parameters are identical: 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 only differences are product status (active versus obsolete) and packaging configuration (tape & reel versus bulk). No circuit or PCB modifications are required.

Q: What is the difference between direct equivalents and similar substitutes?

A: Direct equivalents (DAP222G, DAP222T1G) maintain all electrical and mechanical specifications of the DAP222, including package format. Similar substitutes (BAW56M,315, BAW56TB_R1_00001) maintain the 1 Pair Common Anode configuration and small signal speed classification but feature enhanced voltage and current ratings and different package formats. Similar substitutes require PCB layout modification due to package changes.

Q: Can BAW56M,315 replace the DAP222 in all applications?

A: BAW56M,315 is electrically compatible for applications where the DAP222 specifications are met. It provides enhanced 90 V reverse voltage and 150 mA average rectified current ratings with improved 4 ns reverse recovery time. However, the SOT-883 package format differs from the DAP222 SC-75 (SOT-416) package, requiring PCB layout modification and mechanical validation before implementation.

Q: Is BAW56TB_R1_00001 suitable as a DAP222 replacement?

A: BAW56TB_R1_00001 maintains the 1 Pair Common Anode configuration and small signal speed classification with 150 mA average rectified current and 4 ns reverse recovery time. However, its 75 V reverse voltage rating is below the DAP222 80 V specification. Circuit-level voltage margin analysis is required to confirm suitability. The SOT-523 package format differs from the DAP222 SC-75 (SOT-416) package, requiring PCB layout modification.

Q: What are the compliance differences between the DAP222 and its substitutes?

A: The DAP222 is RoHS non-compliant. All substitute parts (DAP222G, DAP222T1G, BAW56M,315, BAW56TB_R1_00001) are ROHS3 compliant. All parts are REACH Unaffected and carry EAR99 ECCN classification. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all parts.

Q: Which substitute offers the best inventory availability?

A: DAP222T1G offers the highest inventory availability with 62,300 pieces in stock, followed by BAW56TB_R1_00001 (1,127 pieces), DAP222G (1,510 pieces), and BAW56M,315 (758 pieces). For production applications requiring sustained component supply, DAP222T1G is the recommended direct equivalent.

Q: Do package format changes affect circuit performance?

A: Package format changes do not affect electrical circuit performance when the electrical specifications are maintained. However, different package formats (SC-75 versus SOT-883 versus SOT-523) have different physical dimensions, pin spacing, and PCB footprints. PCB layout modification and mechanical validation are required when implementing parts with different package formats.

Q: What is the operating temperature range for all substitute parts?

A: All parts (DAP222, DAP222G, DAP222T1G, BAW56M,315, BAW56TB_R1_00001) specify a maximum junction operating temperature of 150°C. BAW56TB_R1_00001 additionally specifies a minimum junction operating temperature of -55°C, providing a defined operating temperature range of -55°C to 150°C.
