IH4812S Equivalent & Substitute Parts

Part Overview

The XP Power IH4812S is an isolated DC-DC converter module designed for ITE (Commercial) applications, featuring two outputs of +12V and -12V at 84mA each. With an input voltage range of 43.2V to 52.8V, 2W output power, 1kV isolation, and through-hole 6-SIP package, this obsolete product is suitable for setups requiring compact, dual-voltage isolated conversion. Due to its discontinued (obsolete) status, sourcing alternative or equivalent models is necessary for maintenance, replacement, or new designs dependent on the original specifications.

Engineering Selection Recommendations

The IH4812S is classified as obsolete, requiring replacement for continued support or new development. Substitution should account for product status (active vs. obsolete), compliance with ROHS3, and matching ECCN/HTSUS designations. The TRI 3-4822 satisfies all compliance requirements as specified and maintains or exceeds all regulated certifications furnished in the input. Selection between parts should remain within only these compliance and regulatory parameters.

Frequently Asked Questions (FAQ)

Q1: What are the primary parameters required for substituting the IH4812S DC-DC converter?
A1: Key substitution criteria are module type (isolated), number and type of outputs (+12V, -12V), input voltage range, maximum output current, isolation voltage, mounting type, package size, RoHS compliance, and regulatory codes (ECCN, HTSUS).

Q2: Are TRI 3-4822 and IH4812S pin-compatible or package-compatible?
A2: The IH4812S uses a 6-SIP Module, 5 Leads package, while the TRI 3-4822 uses a 24-DIP Module, 6 Leads package. Compatibility for mechanical fit depends strictly on the package outline and lead configuration as described in the parameter comparison table.
