Equivalent & Substitute Parts Reference for ISF0515

Part Overview

Manufacturer Part Number ISF0515 is an isolated DC-DC converter module from XP Power. It is designed to provide two isolated output voltages of +15V and -15V at up to 33mA each, operating from a 4.5V to 5.5V input. The converter is rated for a power output of 1 W with 1 kV isolation and is suitable for ITE (Commercial) applications. The module features surface mount packaging (10-SMD) and compact dimensions. ISF0515 is designated as obsolete, necessitating the identification of alternative models that match the electrical, mechanical, and compliance parameters for continued design or maintenance use.

Engineering Selection Recommendations

Select substitute parts for ISF0515 based on current product status, RoHS compliance, ECCN, and approval certifications. IAS0105D15 offers active status, ROHS3 compliance, and multiple safety approvals (CE, TUV, UL) within the same application category. Substitution can be performed where electrical, mechanical, and compliance criteria provided above are met.

Frequently Asked Questions (FAQ)

What key factors determine if IAS0105D15 can substitute ISF0515? Strictly matching input voltage range, number and value of output voltages, maximum output current, power rating, isolation voltage, mounting type, package dimensions, and application category. Compliance fields and product status are also required for compatibility.
Are there differences in package dimensions or leads? ISF0515 uses a 10-SMD Module package, while IAS0105D15 uses a 10-SMD Module with 6 Leads and slightly increased width and height. Both have surface mount configuration, which maintains installation compatibility.
Is operating temperature range relevant in substitution? Both modules support -40°C, but IAS0105D15 extends to 105°C with derating, and ISF0515 to 85°C. Applications within this range must consider only the specified operating temperatures.
How does RoHS compliance affect component selection? Both modules are ROHS3 Compliant, permitting use in environments requiring environmental compliance.
Does the difference in isolation voltage impact substitution? IAS0105D15 provides a higher isolation voltage (1.5 kV) compared to ISF0515 (1 kV). This difference permits substitution within stricter isolation requirements.
What should be noted regarding product status? ISF0515 is obsolete. IAS0105D15 is active. For production or maintenance, only active products are recommended under the criteria provided.
Are ECCN and HTSUS codes relevant to substitution? Both parts are designated EAR99 for ECCN and 8504.40.9580 for HTSUS, maintaining consistent export and tariff classification.
Can ITE (Commercial) category applications use the substitute? Both ISF0515 and IAS0105D15 are specified for ITE (Commercial) use per manufacturer description, meeting application requirements.
