Equivalent & Substitute Parts for VGDS2-S5-D9-DIP
Part Overview
The VGDS2-S5-D9-DIP by CUI Inc. is an isolated module DC-DC converter featuring dual outputs of +9V and -9V at 111mA each, powered by a 4.5V - 5.5V input. With a maximum output power of 2W, 6 kV isolation voltage, and short-circuit protection (SCP), this converter is suited for ITE (commercial) applications and is housed in a through-hole 24-DIP module. The VGDS2-S5-D9-DIP is marked as obsolete, making it necessary to identify alternative models possessing matching electrical and mechanical parameters to ensure form, fit, and function consistency in critical designs.
