Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 6446-016 is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Power rating: 20VA
• Primary voltage configuration: Dual windings supporting 115V and 230V
• Secondary voltage outputs: Parallel 8V and Series 16V
• Maximum output current: Parallel 2.5A and Series 1.25A
• Isolation voltage: 4000Vrms

Mechanical Parameters (Must Match Exactly):

• Core type: Laminated
• Mounting type: Through Hole
• Termination style: PC Pin
• Physical dimensions: 57.15mm L x 47.63mm W x 36.50mm H

Compliance Considerations:

• RoHS status and REACH compliance are secondary factors that do not affect functional substitution but influence procurement decisions for regulated applications

The substitute part 6446R-016 meets all electrical and mechanical equivalence criteria and is therefore a direct functional substitute.

Parameter Comparison

Engineering Selection Recommendations

The 6446R-016 is a direct functional equivalent to the obsolete 6446-016. Both parts are manufactured by API Delevan Inc. and share identical electrical and mechanical specifications across all critical parameters: 20VA power rating, dual primary windings (115V/230V), dual secondary windings (8V parallel/16V series), 2.5A parallel output current, 1.25A series output current, laminated core construction, through-hole mounting, PC pin termination, and 4000Vrms isolation voltage.

The primary distinction between these parts is product status and regulatory compliance. The 6446-016 is obsolete and RoHS non-compliant, while the 6446R-016 is an active product with ROHS3 compliance. For applications subject to RoHS regulations or requiring long-term component availability, the 6446R-016 is the appropriate selection. For legacy systems or applications without RoHS requirements, either part provides equivalent performance.
