Key Parameters

Substitute Part Grouping Explanation

Substitution of the 6026-048 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Power rating: 20VA
• Primary voltage options: 115V and 230V dual configuration
• Secondary voltage outputs: 24V parallel and 48V series
• Output current capacity: 800mA parallel, 400mA series
• Isolation voltage: 2500Vrms
• Dual primary and dual secondary winding configuration

Mechanical Equivalence Criteria:

• Core type: Laminated
• Mounting: Through hole
• Termination: PC pin
• Physical footprint: 57.15mm L × 47.63mm W
• Height: 36.50mm maximum seated height

The 6026R-048 meets all electrical and mechanical equivalence requirements, differing only in product status (active versus obsolete) and regulatory compliance classification.

Parameter Comparison

Engineering Selection Recommendations

The 6026R-048 is the direct functional equivalent of the 6026-048. Selection between these parts is determined by regulatory and supply chain requirements rather than electrical or mechanical performance differences.

For New Designs and Production: The 6026R-048 is the appropriate selection. This part maintains identical electrical specifications and mechanical form factor while offering active product status and RoHS3 compliance. The active status ensures continued availability and manufacturer support.

For Legacy System Maintenance: The 6026-048 remains functionally equivalent for applications where RoHS compliance is not mandated. However, supply constraints due to obsolete status may limit availability.

Regulatory Considerations: Applications subject to RoHS3 requirements must use the 6026R-048. The 6026-048 is classified as RoHS non-compliant and unsuitable for regulated markets.

Frequently Asked Questions (FAQ)

Q: Can the 6026R-048 directly replace the 6026-048 in existing designs?

A: Yes. The 6026R-048 provides identical electrical performance and mechanical compatibility. No circuit modifications or PCB layout changes are required. The parts are pin-compatible and functionally interchangeable.

Q: What is the primary difference between these parts?

A: The 6026R-048 is the active production equivalent with RoHS3 compliance. The 6026-048 is obsolete and RoHS non-compliant. All electrical and mechanical specifications are identical.

Q: Are there any compatibility issues with through-hole mounting?

A: No. Both parts use identical PC pin termination and through-hole mounting configuration. Footprint and hole spacing are identical at 57.15mm length and 47.63mm width.

Q: Does the 6026R-048 support the same voltage configurations?

A: Yes. Both parts support dual primary windings (115V/230V selection) and dual secondary windings (24V parallel or 48V series configuration). Output current ratings are identical at 800mA parallel and 400mA series.

Q: What is the isolation voltage rating for both parts?

A: Both the 6026-048 and 6026R-048 provide 2500Vrms isolation voltage between primary and secondary windings.

Q: Is the 6026-048 still available for purchase?

A: The 6026-048 is classified as obsolete. While inventory may exist from legacy stock, the 6026R-048 is the recommended active alternative for new orders and ongoing supply assurance.
