Key Parameters

Substitute Part Grouping Explanation

Substitution of the 6445-010 is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications for power rating, voltage configurations, winding arrangements, core type, mounting method, termination style, isolation voltage, and physical dimensions. The API Delevan Inc. 6445R-010 qualifies as a direct substitute because it matches all these critical parameters without deviation. The primary distinction between the main part and its substitute is product status and regulatory compliance, not functional or physical characteristics.

Key Parameters Determining Substitution:

• Power rating: 10VA
• Primary voltage options: 115V, 230V
• Secondary voltage configurations: Parallel 5V, Series 10V
• Secondary current capacity: Parallel 2A, Series 1A
• Dual primary and dual secondary winding architecture
• Laminated core construction
• Through-hole mounting with PC pin termination
• 4000Vrms isolation voltage
• Identical physical envelope: 47.63mm × 39.67mm × 36.50mm

Parameter Comparison

Engineering Selection Recommendations

The 6445R-010 is the direct equivalent substitute for the obsolete 6445-010. Both parts are manufactured by API Delevan Inc. and share identical electrical and mechanical specifications across all functional parameters. The 6445R-010 maintains active product status, ensuring ongoing availability and supply chain reliability. Additionally, the 6445R-010 achieves ROHS3 compliance, whereas the 6445-010 is non-compliant.
