Equivalent & Substitute Parts for PT4583C

Part Overview

Texas Instruments PT4583C is an obsolete isolated DC-DC converter module, designed for applications requiring a single regulated 12V output at up to 2.5A with high isolation (1.5 kV) and multiple protection features. Finding alternatives is necessary for engineers due to its obsolete status and to maintain product availability and ongoing support in new or existing designs.

Substitute Part Grouping Explanation

Substitution is strictly determined by matching the following mandatory parameters within the DC-DC converter isolated module category:

Output voltage (12V)
Maximum output current (2.5A)
Input voltage range (minimum ≥18V, maximum ≥60V)
Power rating (30W)
Isolation voltage (≥1.5kV)
Mounting type and package/case
Functional features (Remote On/Off, protection features)
Application suitability (ITE Commercial)
Compliance (RoHS3, REACH, ECCN, HTSUS)

Engineering Selection Recommendations

Texas Instruments PT4583C is obsolete, and inventory may be limited. Recom Power RP30-4812SFW is active and available. Both parts meet ROHS3 and REACH compliance requirements and share a common ECCN and HTSUS code. The substitute maintains all required electrical parameters, application suitability, and protection features, with the noted distinction of mounting type and package/case.

Frequently Asked Questions (FAQ)

Q1: What are the necessary criteria for substituting PT4583C?
A1: Substitutes must have identical output voltage, output current, input voltage range, isolation voltage rating, power rating, and essential features as specified. Compliance and application type must also match.

Q2: Are there package or mounting differences?
A2: PT4583C uses a surface mount 19-SMD module, while RP30-4812SFW uses a through-hole 6-DIP module. Selection must consider board design compatibility with these formats.

Q3: How does inventory and product status affect selection?
A3: PT4583C is obsolete, while RP30-4812SFW is active with available inventory, making the latter suitable for ongoing supply and new designs.

Q4: Are all safety and protection features matched?
A4: Both parts provide remote on/off and overcurrent/overtemperature protection. RP30-4812SFW adds OVP (overvoltage protection) within the listed features, based on available data.

Q5: Is there a difference in compliance or certifications?
A5: Both parts are ROHS3 compliant and REACH unaffected with matching ECCN and HTSUS codes. Moisture sensitivity levels differ and should be matched to handling processes.
