6026-120 Equivalent & Substitute Parts Reference

Part Overview

The 6026-120 is a laminated core power transformer rated at 20VA with dual primary and secondary windings, manufactured by API Delevan Inc. This through-hole mounted component provides selectable output configurations through series and parallel winding connections, delivering either 60V at 320mA (parallel) or 120V at 160mA (series) from 115V or 230V primary inputs.

The 6026-120 carries an obsolete product status, making identification of functionally equivalent alternatives essential for ongoing system support and procurement planning. Substitute parts must maintain identical electrical performance parameters and physical form factors to ensure direct compatibility in existing designs.

Substitute Part Grouping Explanation

Substitution eligibility for the 6026-120 is determined by strict equivalence across all electrical and mechanical parameters. The following criteria establish direct substitutability:

• Identical power rating (20VA)
• Matching primary voltage inputs (115V, 230V)
• Identical secondary voltage outputs in both series (120V) and parallel (60V) configurations
• Matching maximum output current specifications (320mA parallel, 160mA series)
• Dual primary and dual secondary winding architecture
• Laminated core construction
• Through-hole mounting with PC pin termination
• Equivalent isolation voltage (2500Vrms)
• Compatible physical dimensions and weight

The 6026R-120 meets all substitution criteria as a direct equivalent to the 6026-120, with the primary distinction being active product status and improved compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The 6026R-120 provides complete functional equivalence to the 6026-120 with the advantage of active product status and ROHS3 compliance certification. For new designs or system refreshes, the 6026R-120 is the appropriate selection due to its availability and regulatory compliance posture. For legacy system maintenance where the original 6026-120 is specified, the 6026R-120 serves as a direct drop-in replacement without circuit modification or performance degradation.

The transition from 6026-120 to 6026R-120 introduces no electrical or mechanical incompatibilities. Both components share identical winding configurations, voltage ratings, current capabilities, and physical form factors, ensuring seamless integration into existing PCB layouts and circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the 6026R-120 be used as a direct replacement for the 6026-120 in existing designs?

A: Yes. The 6026R-120 is electrically and mechanically identical to the 6026-120. All voltage ratings, current specifications, winding configurations, and physical dimensions match exactly. No circuit modifications are required.

Q: What is the significance of the product status difference between these parts?

A: The 6026-120 is classified as obsolete, indicating discontinued manufacturing and limited availability. The 6026R-120 maintains active production status, ensuring reliable procurement for current and future applications.

Q: How does RoHS compliance affect substitution eligibility?

A: The 6026R-120 achieves ROHS3 compliance while the 6026-120 does not. This compliance improvement does not affect electrical performance or physical compatibility. For applications subject to RoHS regulatory requirements, the 6026R-120 is the appropriate selection.

Q: Are the physical dimensions and mounting characteristics identical?

A: Yes. Both parts share identical through-hole mounting specifications, PC pin termination, and physical envelope dimensions of 57.15mm L × 47.63mm W × 36.50mm H maximum height. PCB layout modifications are not necessary.

Q: What are the selectable output configurations for these transformers?

A: Both the 6026-120 and 6026R-120 provide dual secondary winding configurations enabling two output modes: parallel connection yields 60V at 320mA maximum, while series connection yields 120V at 160mA maximum. Primary voltage selection between 115V and 230V is also available.

Q: Is the isolation voltage specification identical between these parts?

A: Yes. Both components provide 2500Vrms isolation voltage, maintaining equivalent safety and performance characteristics in isolated power supply applications.
