Substitute Part Grouping Explanation

Substitution eligibility for the 6026-028 is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Power rating: 20VA
• Primary voltage options: 115V and 230V dual configuration
• Secondary voltage outputs: 14V parallel and 28V series
• Output current capacity: 1.4A parallel, 700mA series
• Isolation voltage: 2500Vrms
• Winding configuration: Dual primary and dual secondary

Mechanical Equivalence Criteria:

• Core type: Laminated
• Mounting: Through hole
• Termination: PC pin
• Physical dimensions: 57.15mm L × 47.63mm W × 36.50mm H

The API Delevan 6026R-028 meets all specified electrical and mechanical parameters, establishing it as a direct functional equivalent to the obsolete 6026-028.

Parameter Comparison

Engineering Selection Recommendations

The 6026R-028 is the appropriate selection for applications currently using or requiring the 6026-028 specification. Both components are manufactured by API Delevan Inc. and provide identical electrical and mechanical performance across all specified parameters.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The 6026-028 is classified as obsolete, indicating discontinued production and limited availability. The 6026R-028 maintains active production status with current inventory availability.

The 6026R-028 achieves ROHS3 compliance, meeting current environmental and hazardous substance restrictions. The original 6026-028 is RoHS non-compliant. For applications subject to RoHS requirements or procurement policies mandating compliant components, the 6026R-028 is the required selection.

Both parts share identical REACH status (REACH Unaffected) and ECCN classification (EAR99), presenting no additional regulatory considerations for substitution.

Frequently Asked Questions (FAQ)

Q: Can the 6026R-028 directly replace the 6026-028 in existing designs?

A: Yes. The 6026R-028 provides complete electrical and mechanical equivalence to the 6026-028. All voltage ratings, current capacities, winding configurations, mounting specifications, and physical dimensions are identical. Direct substitution is supported without circuit modification.

Q: What is the significance of the "R" designation in the 6026R-028 part number?

A: The "R" designation indicates a revised version of the original 6026 series transformer. In this case, the revision includes ROHS3 compliance while maintaining all functional specifications of the original design.

Q: Are there any compliance differences between these parts?

A: The 6026R-028 is ROHS3 compliant, while the 6026-028 is RoHS non-compliant. Both parts are REACH Unaffected and carry identical ECCN classification. For applications requiring RoHS compliance, the 6026R-028 is the appropriate selection.

Q: What is the availability status of each part?

A: The 6026-028 is classified as obsolete with limited remaining inventory (655 pieces). The 6026R-028 is in active production with current inventory availability (674 pieces). For new designs or long-term supply requirements, the 6026R-028 is recommended.

Q: Are the physical dimensions and mounting footprints identical?

A: Yes. Both transformers share identical dimensions of 57.15mm length × 47.63mm width × 36.50mm maximum seated height. Through-hole PC pin termination is identical on both parts. PCB layout and mechanical mounting require no modification.

Q: Do both parts support the same voltage and current configurations?

A: Yes. Both the 6026-028 and 6026R-028 support dual primary windings (115V or 230V selection) and dual secondary windings (14V parallel at 1.4A or 28V series at 700mA). Output configuration selection is identical between parts.
