Key Parameters

Substitute Part Grouping Explanation

Substitute parts are determined based strictly on the following key electrical, mechanical, and regulatory parameters: type (isolated module), number of outputs, input voltage range, output voltage, output current, power rating, voltage isolation, mounting type, package/case, RoHS status, and qualification for ITE (Commercial) applications. Only products matching these values or providing equivalent performance within specified tolerances are included as substitutes.

Parameter Comparison

Engineering Selection Recommendations

ISF0512A has been classified as obsolete, making IFS0105S12 the designated substitute based on identical functional and regulatory parameters. Key considerations for selection include active product status, matching RoHS3 compliance, comparable isolation voltage, and suitability for ITE (Commercial) applications. Both parts share the same mounting type and package/case format, supporting direct interchangeability within the specified mechanical tolerances. Regulatory identifiers (ECCN, HTSUS) remain consistent.

Frequently Asked Questions (FAQ)

Q1: What electrical criteria determine substitution compatibility between ISF0512A and IFS0105S12?
A1: Substitution is based on type (isolated module), input voltage (4.5V–5.5V), output voltage (12V), output current (84mA), power rating (1 W), and number of outputs (1).

Q2: Are package and mounting types identical for both parts?
A2: Both ISF0512A and IFS0105S12 utilize the 8-SMD surface-mount module format, providing compatibility for PC board layout and assembly processes.

Q3: Does the substitute part meet the same regulatory and compliance standards?
A3: Yes, both models are ROHS3 compliant, fall under the same ECCN and HTSUS codes, and are qualified for ITE (Commercial) applications.

Q4: Are there physical dimension tolerances to consider when replacing ISF0512A with IFS0105S12?
A4: The substitute part, IFS0105S12, has slightly larger dimensions. Compare the specified sizes for mechanical fit within your application.

Q5: Why is finding a substitute for ISF0512A necessary?
A5: ISF0512A is obsolete. Continued availability for manufacturing or maintenance requires a compatible part with equivalent key parameters and compliance.

Q6: Does the substitute, IFS0105S12, offer additional certifications not present in ISF0512A?
A6: IFS0105S12 carries CE, TUV, and UL approvals with standard number 62368-1, as provided in the input parameters.
