RAC03-12SA Equivalent & Substitute Parts Reference
Part Overview
The RAC03-12SA is an enclosed AC/DC converter designed for ITE (Commercial) applications, delivering a single 12V output at up to 250mA (3W max) from a universal 90~264 VAC input. This product, part of Recom Power's POWERLINE RAC03-A (3W) series, has reached Obsolete status, which necessitates seeking valid equivalents or substitutes for new designs and ongoing production needs.

Substitute Part Grouping Explanation
Substitute parts for the RAC03-12SA must strictly match the electrical and mechanical parameters essential for device interchangeability within the enclosed AC/DC converter category. The following criteria are used for valid substitution:
- Output Voltage: 12V
- Output Current: 250mA (max)
- Input Voltage Range: 90 ~ 264 VAC
- Power: 3W
- Number of Outputs: 1
- Application: ITE (Commercial)
- Mounting Type: Through Hole
- Efficiency: 76%
- RoHS/REACH Compliance
- Operating Temperature Range
- Package Form Factor
Only parts explicitly matching these parameters, as provided, are listed as substitutes.

Engineering Selection Recommendations
Since the RAC03-12SA is obsolete, selection of substitute parts must be based on maintained electrical parameters (input/output voltages and currents), power rating, mounting style, and RoHS/REACH compliance status. Substitute part RAC03-12SC is also compliant to ROHS3 and REACH, with identical core specifications for voltage, current, and power. Both parts have Through Hole mounting, support single output operation at 12V/250mA, and share an efficiency of 76%. Product status and compliance are required considerations.
Frequently Asked Questions (FAQ)
Q1: What are the critical electrical parameters for substituting RAC03-12SA?
A1: Output voltage (12V), output current (250mA), input voltage range (90~264 VAC), and power rating (3W) are critical for substitution.
Q2: Are package dimensions and mounting type important in substitution?
A2: Yes. Substitutes must use Through Hole mounting. Package form factors differ (SIP vs DIP), which may influence PCB compatibility.
Q3: Are all listed substitutes RoHS and REACH compliant?
A3: Both RAC03-12SA and RAC03-12SC are specified as ROHS3 compliant and REACH unaffected.
Q4: Can differences in line and load regulation affect substitution?
A4: Substitutes must be evaluated for regulation characteristics within allowed application tolerances. RAC03-12SC has higher specified regulation percentages.
Q5: Do substitutes retain the same application category?
A5: Both parts are categorized for ITE (Commercial) applications.
