Equivalent & Substitute Parts Reference for PT4214C

Part Overview

The PT4214C from Texas Instruments is an obsolete isolated DC-DC converter module designed for ITE (commercial) applications. The module delivers a single 12V output at up to 600mA from a 38V–75V input, with a maximum output power of 7 W and 1.5 kV isolation. Given its obsolescence, it is necessary to identify substitute models to maintain design continuity in existing systems or for maintenance, ensuring fit, function, and safety remain uncompromised.

Substitute Part Grouping Explanation

Substitution for the PT4214C is determined strictly by matching or exceeding core electrical and mechanical parameters relevant for DC-DC converter modules: input voltage range, output voltage, maximum output current, output power, voltage isolation rating, number of outputs, mounting type, and package specifications. Compliance and application field (ITE/Commercial) are also required criteria for valid substitution. The listed alternative part, REC7.5-4812SRW/H2/A/M/SMD, is included based solely on these specified parameters.

Engineering Selection Recommendations

The PT4214C is obsolete, while the REC7.5-4812SRW/H2/A/M/SMD is active and currently available. Both parts meet ROHS3 and REACH compliance, and both have MSL 1 status, indicating unlimited shelf life. Only those parts matching provided compliance and certification information are considered for substitution.

Frequently Asked Questions (FAQ)

Q1: What key parameters must be matched when substituting a DC-DC converter module like the PT4214C?
A1: Parameters including input voltage range, output voltage, output current, output power, isolation voltage, mounting type, and packaging must be matched or exceeded. Compliance and intended application (ITE/commercial) must also be confirmed.

Q2: Are there package or pinout differences between PT4214C and REC7.5-4812SRW/H2/A/M/SMD?
A2: The PT4214C uses an 18-SMD Module, 6 Leads package; REC7.5-4812SRW/H2/A/M/SMD uses a 24-SMD Module, 18 Leads package. Only parameters shown above are considered for package compatibility.

Q3: Does product compliance (ROHS3, REACH) differ between these parts?
A3: Both PT4214C and REC7.5-4812SRW/H2/A/M/SMD are ROHS3 Compliant and REACH Unaffected.

Q4: Can substitute parts be used in the same applications as the obsolete PT4214C?
A4: Both parts are intended for ITE (Commercial) applications, as specified in the provided parameters.

Q5: How does the operating temperature range compare?
A5: PT4214C operates from -40°C to 85°C. REC7.5-4812SRW/H2/A/M/SMD operates from -40°C to 71°C. Only provided parameter values are considered in comparison.
