API Delevan Inc. 6494-036 Power Transformer Equivalent & Substitute Parts

Part Overview

The API Delevan Inc. 6494-036 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 36V (series) or 18V (parallel). The 6494-036 is classified as obsolete, necessitating identification of active equivalent components to maintain design continuity and ensure ongoing component availability for production and field service applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 6494-036 is determined by strict equivalence across all electrical and mechanical parameters. The substitute component must maintain identical specifications for power rating, primary and secondary voltage configurations, output current capabilities, winding arrangements, physical dimensions, mounting methodology, termination style, and isolation voltage rating.

The API Delevan Inc. 6494R-036 qualifies as a direct substitute based on the following criteria:

Parameter Comparison

Engineering Selection Recommendations

The 6494R-036 is the direct active equivalent for the obsolete 6494-036. Both components are manufactured by API Delevan Inc. and maintain identical electrical and mechanical specifications across all critical parameters including power rating, voltage configurations, current capacity, winding arrangements, physical dimensions, and isolation voltage.

The primary distinction between these components is product status and regulatory compliance. The 6494-036 is classified as obsolete and carries non-compliant RoHS status. The 6494R-036 is an active product with ROHS3 compliance and REACH unaffected designation, making it suitable for applications requiring current regulatory adherence.

For new designs and ongoing production requiring 25VA laminated core power transformers with dual primary and secondary windings, flexible voltage configuration (115V/230V primary, 36V/18V secondary), and chassis mount termination, the 6494R-036 is the appropriate component selection. The electrical and mechanical compatibility ensures direct substitution without circuit redesign or mechanical modification.

Frequently Asked Questions (FAQ)

Q: Can the 6494R-036 directly replace the 6494-036 in existing applications?

A: Yes. The 6494R-036 maintains identical electrical specifications (25VA power rating, 115V/230V primary, 36V/18V secondary, 700mA/1.4A output current), winding configuration (dual primary and secondary), physical dimensions (71.44mm L x 47.63mm W x 58.74mm H), mounting type (chassis mount), and termination style (solder, quick connect). Direct substitution is supported without circuit modification or mechanical redesign.

Q: What is the significance of the RoHS compliance difference?

A: The 6494-036 is RoHS non-compliant, while the 6494R-036 is ROHS3 compliant. ROHS3 compliance indicates the component meets current Restriction of Hazardous Substances regulations. For applications subject to regulatory requirements or procurement standards mandating RoHS compliance, the 6494R-036 is the appropriate selection.

Q: Are the physical dimensions identical between both components?

A: Yes. Both the 6494-036 and 6494R-036 share identical physical dimensions of 71.44mm length, 47.63mm width, and 58.74mm maximum seated height. Chassis mount applications require no mechanical modification.

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

A: Both components provide 4000Vrms isolation voltage, meeting identical electrical safety specifications.

Q: Why is the 6494-036 classified as obsolete?

A: The 6494-036 is no longer in active production. The 6494R-036 represents the current active equivalent from API Delevan Inc., offering identical functionality with updated regulatory compliance.

Q: Are there any differences in termination options?

A: No. Both components support identical termination styles: solder and quick connect. Existing wiring and connection methodologies remain compatible.

Q: What is the current inventory status?

A: The 6494-036 (obsolete) has 723 pieces in stock. The 6494R-036 (active) has 693 pieces in stock. For long-term component availability, the active 6494R-036 is recommended.
