Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAS21-7-G is based on the following criteria derived from the provided parameters:

Primary Substitution Criteria:

• Identical base product number (BAS21)
• Identical manufacturer (Diodes Incorporated)
• Identical package classification (SOT-23 family)
• Matching RoHS compliance status (ROHS3 Compliant)
• Matching moisture sensitivity level (MSL 1)
• Matching REACH status (REACH Unaffected)

The BAS21-7-F qualifies as a direct substitute because it maintains all critical electrical and mechanical parameters within the BAS21 product family while offering active product status and improved availability.
