Key Parameters

Substitute Part Grouping Explanation

Substitution of power transformers requires strict alignment across all electrical and mechanical parameters that determine form, fit, and function within the host system. The following parameters establish the substitution criteria for the 6027-120:

Electrical Parameters (Critical):

• Voltage ratings (primary and secondary configurations)
• Power rating (36VA)
• Output current capabilities
• Isolation voltage rating
• Winding configuration (dual primary, dual secondary, no center tap)

Mechanical Parameters (Critical):

• Physical dimensions (66.68mm L × 55.55mm W)
• Seated height (39.67mm maximum)
• Mounting type (through-hole)
• Termination style (PC pin)

The API Delevan 6027R-120 meets all substitution criteria, providing identical electrical specifications and mechanical form factor while offering updated product status and compliance documentation.

Engineering Selection Recommendations

The API Delevan 6027R-120 serves as the direct functional equivalent for the obsolete 6027-120, with complete electrical and mechanical compatibility. The transition to the 6027R-120 is supported by the following factors:

Product Status: The 6027-120 carries obsolete designation, limiting long-term procurement viability. The 6027R-120 maintains active product status, ensuring continued availability and manufacturing support.

Regulatory Compliance: The 6027R-120 achieves RoHS3 compliance, meeting current regulatory requirements for electronic components in applicable jurisdictions. This compliance status addresses modern supply chain restrictions on restricted substances.

Identical Form and Function: All electrical parameters (voltage ratings, current ratings, power rating, isolation voltage, winding configuration) and mechanical parameters (dimensions, height, mounting method, termination style) are identical between the two part numbers, enabling direct substitution in existing designs without circuit modification.

Continuity: Both transformers carry the same REACH unaffected status and EAR99 export classification, maintaining consistent regulatory and export documentation.

Frequently Asked Questions (FAQ)

Q: Can the 6027R-120 be used as a direct replacement for the 6027-120 in existing designs? A: The 6027R-120 provides complete form, fit, and function equivalence to the 6027-120. All electrical specifications (voltage, current, power rating, isolation) and mechanical specifications (dimensions, mounting, termination) are identical, enabling direct substitution without design modification.

Q: What is the primary difference between these two part numbers? A: The 6027-120 is obsolete, while the 6027R-120 carries active product status. Additionally, the 6027R-120 achieves RoHS3 compliance compared to the non-compliant status of the 6027-120. All functional and physical characteristics are identical.

Q: Are the printed circuit board mounting hole patterns identical? A: The physical dimensions (66.68mm L × 55.55mm W, 39.67mm maximum seated height) and mounting type (through-hole) are identical for both parts. The PC pin termination style is consistent between both transformers.

Q: Does RoHS3 compliance of the 6027R-120 affect circuit performance? A: RoHS3 compliance affects material composition and restriction of certain substances; it does not alter electrical performance, voltage ratings, current capacity, or power rating. Circuit behavior remains identical.

Q: Are there voltage selection differences between series and parallel winding configurations? A: Both the 6027-120 and 6027R-120 support identical series/parallel winding configurations: 120V series output at 300mA, or 60V parallel output at 600mA. The primary voltage remains selectable between 115V and 230V for both configurations.

Q: What is the isolation voltage rating, and does it differ between the parts? A: Both transformers provide 2500Vrms isolation voltage rating, meeting high-voltage isolation requirements for safety-critical applications.
