XP Power ISE0312A Equivalent & Substitute Parts Reference

Part Overview

The XP Power ISE0312A is an isolated DC-DC converter module designed for ITE (commercial) applications. It features a single output of 12V at 84mA, operates with an input voltage range of 2.97V to 3.63V, and provides 1W of output power with 1.5 kV isolation. The module is surface-mounted in an 8-SMD package and has a product status marked as obsolete. Due to its discontinuation, it is necessary to identify equivalent substitute models with matching electrical and mechanical parameters for use in both legacy and new designs.

Engineering Selection Recommendations

Selection of IES0103S12 as a substitute for ISE0312A is based on matching electrical specifications, package style, and mechanical dimensions within the defined tolerances. The IES0103S12 maintains active product status and is compliant with CE, UKCA, and UL certifications, as well as ROHS3 environmental standards. The ISE0312A is obsolete; replacing with an active, compliant device such as IES0103S12 ensures continued support and adherence to updated regulatory requirements.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters to verify when selecting an equivalent to ISE0312A?

Only input voltage range, output voltage and current, output power, isolation voltage, number of outputs, mounting type, package/case dimensions, operating temperature, and application category are used for equivalence.

Q2: Is the package compatibility maintained between ISE0312A and its substitutes?

Both use an 8-SMD Module, 5 Leads surface mount package, maintaining mechanical and mounting compatibility.

Q3: How do compliance and certifications affect substitution in this category?

Substitute parts must match or exceed established compliance requirements. IES0103S12 provides CE, UKCA, UL, and is ROHS3 compliant, supporting direct substitution for regulated markets.

Q4: Can slight variations in output current and dimensions affect replacement suitability?

Only parts with matching or very close output current, power rating, and similar mechanical dimensions are included for substitution within this product category.

Q5: Why is substitution necessary for the ISE0312A model?

ISE0312A is obsolete; substituting ensures availability, continued compliance, and compatibility for both legacy maintenance and new product integration.

Q6: Are there any differences in thermal or efficiency characteristics that affect selection?
