Substitute Part Grouping Explanation

Substitution of the obsolete ATS137-PG-A-A is based on the following critical parameters that must remain consistent:

• Manufacturer: Diodes Incorporated (same manufacturer ensures design compatibility and quality standards)
• Function: Unipolar Switch with Hall Effect technology
• Package / Case: 3-SIP, Formed Leads (mechanical and electrical interface compatibility)
• Mounting Type: Through Hole (PCB assembly compatibility)
• Output Type: Open Collector (circuit interface requirement)
• Compliance: ROHS3 Compliant, REACH Unaffected (regulatory alignment)

The AH3373-PG-A meets all substitution criteria as an active product from the same manufacturer with identical package specifications and functional classification.
