Equivalent & Substitute Parts Reference: ISA0305-H

Part Overview

The XP Power ISA0305-H is an isolated module DC-DC converter intended for ITE (Commercial) applications. It provides two regulated outputs: +5V and -5V at a maximum current of 100mA each, from a 2.97V to 3.63V input voltage range. The module delivers 1W power and features 3 kV isolation voltage, surface mount package, and RoHS3 compliance. As the ISA0305-H is currently obsolete, identifying suitable substitute parts is necessary to maintain supply continuity for replacement and design-in.

• Output voltages: +5V and -5V
• Maximum output current: 100mA per output
• Input voltage range: 2.97V to 3.63V
• Isolation voltage: 3 kV
• Power rating: 1 W
• Mounting type: Surface Mount
• Package/case: 10-SMD Module, 6 Leads
• Operating temperature range: -40°C to 105°C
• RoHS compliance

Parameter Comparison

Engineering Selection Recommendations

Given the obsolete status of ISA0305-H, selection of substitute parts should prioritize matching electrical parameters, package format, operating temperature, and regulatory/compliance requirements. Both ISA0305-H and E0305XT-1WR3 are ROHS3 compliant and present identical core functional specifications. The E0305XT-1WR3 maintains the necessary regulatory status (EAR99, RoHS3 Compliant), dimensions, and mounting type suitable for direct substitution.

Frequently Asked Questions (FAQ)

Q: What are the essential parameters to consider when selecting a substitute for ISA0305-H?
A: Output voltages, maximum output currents, input voltage range, isolation voltage, power rating, mounting type, package dimensions, operating temperature, and RoHS compliance.

Q: Is the substitute part compatible with the same PCB footprint as ISA0305-H?
A: Both parts share the 10-SMD Module, 6 Leads package and surface mount configuration. Marginal size variation may exist, but mounting compatibility matches specified input parameters.

Q: Are there any differences in electrical operating ranges between the original and substitute?
A: Electrical operating ranges, isolation voltage, and output specifications are identical per input parameters.

Q: Does the substitute part comply with equivalent environmental and regulatory standards?
A: Both parts are RoHS3 compliant according to provided parameters. Moisture sensitivity and ECCN status also align within the category requirements.

Q: Why is substitution required for ISA0305-H?
A: The product is obsolete and not available for new designs or ongoing production needs. Substitute parts are necessary to maintain system functionality without redesign.

Q: Is there any notable difference in efficiency between the ISA0305-H and its substitute?
A: The E0305XT-1WR3 shows a higher efficiency as per the provided data.
