Key Parameters

Substitute Part Grouping Explanation

Substitute selection for XP Power ISE0503A-H is governed strictly by matching the key operational and mechanical parameters of the original device. These criteria include the input voltage range (4.5V to 5.5V), output voltage (3.3V), maximum output current (303mA), power rating (1W), mounting type (surface mount), package/case configuration (8-SMD Module, 5 Leads), efficiency (74%), and compliance with ROHS3 requirements. Only substitutes that adhere strictly to these parameters are considered.
