Key Parameters

Substitute Part Grouping Explanation

Substitute components for DC-DC converter modules are grouped strictly by matching electrical and mechanical parameters. The key criteria for valid substitution are: output voltage (9V), output current (2A), input voltage range (minimum and maximum values), number of outputs (1), mounting type (through hole), package (3-SIP Module), efficiency (95%), operating temperature (overlapping range), and compliance status (RoHS, ECCN). These criteria are used to identify compatible substitute parts.
