Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VWRAS2-D24-D9-SIP are identified based solely on matching parameters critical for DC-DC converter selection. These parameters include input voltage range (18V – 36V), dual output voltages (+9V, -9V), maximum output currents (111mA per channel), total output power (2W), isolation voltage, packaging (8-SIP Module, 7 leads), mounting type (Through Hole), operating temperature range (-40°C ~ 85°C), RoHS compliance, and application suitability (ITE/commercial). Only products meeting all these criteria are considered valid, direct substitutes.

Key matching parameters:

• Input voltage range
• Output voltages and currents
• Isolation voltage
• Package style and dimensions
• Mounting method
• Operating temperature range
• Regulatory compliance and product status
