Equivalent & Substitute Parts: API Delevan Inc. 6494-012

Part Overview

The API Delevan Inc. 6494-012 is a laminated core power transformer rated at 25VA with dual primary and secondary windings. This component is classified as obsolete and is no longer in active production. The 6494-012 provides flexible voltage configurations through its dual winding architecture, supporting both 115V and 230V primary inputs with corresponding secondary outputs of 6.3V (parallel) or 12.6V (series). Due to its obsolete status and non-compliance with current RoHS3 standards, identification of active equivalent components is necessary for new designs and ongoing system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 6494-012 is based on electrical and mechanical parameter equivalence. The primary criteria for substitution include:

Electrical Parameters:

• Identical power rating (25VA)
• Matching primary voltage inputs (115V, 230V)
• Matching secondary voltage outputs in both parallel (6.3V) and series (12.6V) configurations
• Equivalent maximum output current specifications (4A parallel, 2A series)
• Identical isolation voltage rating (4000Vrms)
• Matching winding configuration (dual primary, dual secondary)

Mechanical Parameters:

• Identical core type (laminated)
• Matching mounting type (chassis mount)
• Compatible termination style (solder, quick connect)
• Identical physical dimensions and height specifications

Compliance Parameters:

• Active product status (versus obsolete)
• Current regulatory compliance certifications

The 6494R-012 meets all electrical and mechanical parameter requirements for direct substitution with the 6494-012.
