Equivalent & Substitute Parts for PT4563C (Texas Instruments)

Part Overview

The PT4563C from Texas Instruments is an isolated DC-DC converter module designed for applications requiring a regulated 12V output at up to 2.5A, with a wide input voltage range (36V–75V). As an obsolete module, sourcing the PT4563C for new designs or ongoing production can present supply chain challenges. Seeking alternative models with equivalent performance and compliance ensures uninterrupted product lifecycle and adherence to regulatory standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution options are grouped strictly by matching core electrical and mechanical parameters required for DC-DC isolated module compatibility. These include output voltage (12V), output current rating (2.5A), power rating (30W), isolation voltage, application scope (ITE Commercial), comparable features, efficiency, compliance with RoHS and REACH, mounting type, package/case style, and environmental ratings. Only module types with these equivalent specifications qualify for direct part substitution.

Parameter Comparison

Engineering Selection Recommendations

For the PT4563C, which is obsolete, substitute selection must ensure equivalent power output, output voltage, output current, isolation voltage, compliance (RoHS3, REACH, ECCN), and application suitability (ITE Commercial). RP30-2412SFW from Recom Power is an active model with matching output parameters, certified compliance, and similar feature sets. Users must also confirm suitability regarding mounting type and package/case style strictly as specified.

Frequently Asked Questions (FAQ)

Q1: What criteria must be met for a DC-DC converter module to substitute PT4563C?
A1: Substitute modules must match output voltage (12V), output current (2.5A), power rating (30W), isolation voltage, must be RoHS3 and REACH compliant, suitable for ITE commercial applications, and align with listed features and environmental ratings.

Q2: Are the mounting types and package/case styles interchangeable between PT4563C and RP30-2412SFW?
A2: PT4563C uses surface mount (19-SMD Module); RP30-2412SFW uses through hole (6-DIP Module). Selection must account for layout and assembly compatibility with the existing PCB and manufacturing process.

Q3: Should dimensional differences affect the substitution decision?
A3: Yes, the physical size and case must be compatible with the intended mechanical design and available space.

Q4: What compliance certifications are necessary for substitution?
A4: RoHS3 compliance, REACH unaffected status, ECCN EAR99, and relevant HTSUS codes must all match between the main part and any substitute.

Q5: Do feature sets such as protection modes and remote controls need to match?
A5: Features such as Remote On/Off, OCP, OTP, SCP, UVLO/OVP must be matched as specified to ensure functionality in the intended application.

Q6: Can substitutes with wider or narrower input voltage ranges be considered?
A6: Only input voltage ranges encompassing the application requirements are permitted. Comparison must strictly follow the provided min/max parameters.
