Substitute Part Grouping Explanation
Substitute parts for the ISF0515A are determined strictly by matching key electrical and mechanical parameters. The following criteria are used:
- Manufacturer and product category
- Output voltage (15V) and maximum output current (67mA)
- Input voltage range (4.5V to 5.5V)
- Power rating (1 W)
- Isolation voltage (≥1 kV)
- Surface mount package with comparable form factor
- Compliance status (ROHS3)
- Application type (ITE Commercial)
- Matching or overlapping operating temperature range
Only parts providing identical or superior values in these parameters are considered direct substitutes.

Engineering Selection Recommendations
The ISF0515A is obsolete. The IES0105S15 is an active, ROHS3-compliant part with a matching input voltage range, output voltage, output current, power rating, and application suitability. It provides a higher isolation voltage, higher efficiency, an extended operating temperature range, and comparable mounting and packaging attributes.
Frequently Asked Questions (FAQ)
Q1: What are the most important criteria for substituting the ISF0515A?
A1: Key criteria include matching input voltage range (4.5V–5.5V), output voltage (15V), output current (67mA), power rating (1 W), isolation voltage (minimum 1 kV), surface mount form factor, RoHS compliance, and application suitability for ITE (commercial).
Q2: Is the IES0105S15 mechanically compatible with the ISF0515A?
A2: Both devices use a surface-mount module format with similar physical dimensions. Verification of PCB pad compatibility is determined by the provided size and package/case data.
Q3: Does the IES0105S15 meet or exceed the electrical parameters of the ISF0515A?
A3: The IES0105S15 matches all key electrical parameters and exceeds the original isolation rating and efficiency.
Q4: Are there compliance or certification differences between these parts?
A4: Both parts are ROHS3 compliant. The IES0105S15 includes approval agency listings and meets standard number 62368-1.
Q5: Should operating temperature range be considered when substituting?
A5: Yes, the substitute provides a broader operating temperature range, fully encompassing the original device's specified range.
