API Delevan 6494-020 Equivalent & Substitute Parts

Part Overview

The API Delevan 6494-020 is a laminated core power transformer rated at 25VA with dual primary and secondary windings. This component provides flexible voltage configurations through series and parallel winding arrangements, supporting both 115V and 230V primary inputs with corresponding secondary outputs of 20V (series) or 10V (parallel). The 6494-020 is classified as obsolete, necessitating identification of active equivalent components for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 6494-020 with the active 6494R-020 is based on electrical and mechanical parameter equivalence. Both components maintain identical specifications across all critical performance parameters: 25VA power rating, dual primary and secondary winding configurations, 115V/230V primary voltage selection, 20V series and 10V parallel secondary outputs, 1.25A and 2.5A maximum output currents respectively, 4000Vrms isolation voltage, laminated core construction, chassis mount configuration, and solder/quick connect termination options. Physical dimensions and mounting footprint are identical, enabling direct mechanical substitution. The primary distinction between these components is product status and regulatory compliance: the 6494-020 is obsolete and RoHS non-compliant, while the 6494R-020 is active production and ROHS3 compliant with REACH unaffected status.

Parameter Comparison

Engineering Selection Recommendations

The 6494R-020 serves as the direct active equivalent for the obsolete 6494-020. Selection of the 6494R-020 is appropriate for applications requiring continued component availability and regulatory compliance. The 6494R-020 maintains full electrical and mechanical compatibility with the 6494-020 across all specified parameters while offering ROHS3 compliance and active production status. The component is suitable for new designs and production continuity where the 6494-020 is no longer available. No performance degradation or functional limitation results from this substitution.

Frequently Asked Questions (FAQ)

Q: Are the 6494-020 and 6494R-020 electrically identical?
