Equivalent & Substitute Parts for IK4812SA

Part Overview

The XP Power IK4812SA is an isolated module DC-DC converter delivering a single regulated 12V output at up to 20.8mA from a 43.2V to 52.8V input. With a maximum output power of 250mW and 1kV isolation, this converter is suitable for ITE (Commercial) applications. The product is classified as obsolete, necessitating the identification of equivalent or substitute models to maintain system compatibility and long-term support in applications requiring these specific electrical and mechanical parameters.

Engineering Selection Recommendations

IK4812SA is designated as obsolete status, and MER1S4812SC is recommended based on maintained electrical parameters, through hole mounting, and ROHS3 compliance. Both models support the required application classification and environmental specifications stated in the input.

Frequently Asked Questions (FAQ)

Q: What are the most important criteria for selecting a substitute for IK4812SA?
A: The substitute must match input voltage range, output voltage, isolation rating, operating temperature, mounting type, application, and compliance status.

Q: Is the package size or pin configuration of MER1S4812SC directly compatible with IK4812SA?
A: Only the provided dimensions and package styles are available. Both are through hole mount with specified length, width, and height measurements. MER1S4812SC uses a 7-SIP Module, 4 Leads, while IK4812SA uses a 4-SIP Module.

Q: Are there differences in electrical capability between IK4812SA and its substitute?
A: MER1S4812SC offers higher output current (84mA) and power rating (1W); both meet or exceed the specifications for the input voltage, output voltage, isolation voltage, and operating temperature.

Q: Can MER1S4812SC be used in all ITE (Commercial) applications where IK4812SA was specified?
A: The application field is identical, supporting substitution within ITE (Commercial) categories based on the provided parameters.

Q: What compliance statuses are relevant for substituting IK4812SA?
A: Both main and substitute parts are ROHS3 Compliant and suitable for the inventory and regulatory requirements specified.
