Engineering Selection Recommendations

The ISJ0515A is obsolete. The substitute part DCV010515P-U from Texas Instruments is active, matches all critical electrical and mechanical parameters, is ROHS3 Compliant, and is suitable as an equivalent replacement within the specified criteria. The moisture sensitivity levels differ; ISJ0515A is MSL 1, while DCV010515P-U is MSL 3.

Frequently Asked Questions (FAQ)

Q: What parameters are critical when selecting a substitute for the ISJ0515A?
A: The critical parameters include input voltage range (4.5V - 5.5V), output voltage (15V), maximum output current (67mA), output power (1W), isolation voltage (1.5kV), operating temperature range (-40°C ~ 85°C), module type, package, mounting style, and relevant compliance (RoHS3, MSL).

Q: Is the package of DCV010515P-U directly compatible with the ISJ0515A?
A: Both utilize a 14-SMD Module, 7 Leads package. The mechanical dimensions are similar but not identical. Review detailed dimensions for direct PCB footprint compatibility.

Q: Are there differences in compliance that affect replacement?
A: Both parts are ROHS3 compliant. The ISJ0515A is MSL 1 (Unlimited), whereas DCV010515P-U is MSL 3 (168 Hours); this may impact handling and soldering processes.

Q: Do both parts provide short circuit protection (SCP)?
A: Yes, both parts offer SCP as a feature. The substitute, DCV010515P-U, also includes over-temperature protection (OTP).

Q: Can the substitute part be used in the same commercial ITE applications as ISJ0515A?
A: Yes, both parts are categorized for use in ITE (Commercial) applications.
