ISK1212A Equivalent & Substitute Parts Reference

Part Overview

The ISK1212A, manufactured by XP Power, is an obsolete DC-DC converter—a 12V, 250mW isolated module with a single output and 1.5kV isolation voltage. As the ISK1212A is marked obsolete and no longer in current production, it is necessary to identify equivalent substitute parts to ensure uninterrupted design support, maintenance, and replacement of existing systems requiring this converter.

Key Parameters

Substitute Part Grouping Explanation

Substitution is established using a parameter-matching method strictly based on: mounting type, isolation voltage, input and output voltages, output current, power rating, package, number of outputs, features, operating temperature, and compliance status. Only components matching or exceeding the critical electrical and mechanical parameters of the ISK1212A within its product category, and with compatible surface-mount packaging, are included.

Parameter Comparison

Engineering Selection Recommendations

ISM1212A is obsolete with limited availability as indicated. PDS1-S12-S12-M-TR from CUI Inc. is an active product with RoHS compliance, identical input and output voltage ranges, output configuration, isolation voltage, features, surface mount package, and mechanical dimensions. Both parts are categorized for ITE (Commercial) applications and feature Moisture Sensitivity Level 1 (Unlimited).

Frequently Asked Questions (FAQ)

Q1: What parameters are critical when selecting a substitute DC-DC converter for ISK1212A?
A1: Key parameters include mounting type, input voltage range, output voltage and current rating, isolation voltage, package/case, features, overall efficiency, operating temperature range, compliance status, and application category.

Q2: Is the package and pin configuration compatible between ISK1212A and PDS1-S12-S12-M-TR?
A2: Both components utilize an 8-SMD Module, 5 Leads surface mount package with matching physical dimensions.

Q3: Are the electrical characteristics directly compatible?
A3: Both parts provide a 12V output at the same input voltage range, with PDS1-S12-S12-M-TR supporting a higher maximum output current and power while offering the same isolation voltage and output type.

Q4: Does substituting PDS1-S12-S12-M-TR affect regulatory compliance or assembly process?
A4: Both parts are RoHS compliant and rated at Moisture Sensitivity Level 1 (Unlimited), which maintains process compatibility.

Q5: How should temperature requirements be considered in selection?
A5: Both converters support an operating temperature range of -40°C to 105°C; PDS1-S12-S12-M-TR specifies this range with derating. Application-specific design constraints should be cross-checked against the converter’s derating profile, if provided.

Q6: Is multi-sourcing possible based on this reference?
A6: Both the main and substitute parts share equivalent packages and critical parameters, enabling direct replacement within the documented parameter set.
