Engineering Selection Recommendations

The API Delevan 6495R-036 is the direct substitute for the obsolete 6495-036 model. All electrical specifications, mechanical dimensions, and functional parameters are identical between the two components.

Product Status Consideration: The 6495-036 is classified as obsolete, indicating discontinued manufacturing and limited availability. The 6495R-036 maintains active product status with current manufacturing support and documented inventory availability.

Compliance Advantage: The 6495R-036 achieves RoHS3 compliance, whereas the 6495-036 is non-compliant. For applications subject to environmental regulations or customer requirements mandating RoHS compliance, the 6495R-036 provides regulatory alignment without electrical or mechanical compromise.

Supply Chain: The 6495R-036 is available in active inventory (693 pieces documented), ensuring procurement reliability for new production and field replacement applications.

Frequently Asked Questions (FAQ)

Q: Are the 6495-036 and 6495R-036 electrically interchangeable?

A: Yes. Both transformers provide identical electrical specifications: 43VA power rating, dual primary windings (115V/230V selectable), dual secondary windings (18V parallel or 36V series), and 4000Vrms isolation voltage. Output current ratings are identical in both configurations (2.4A parallel, 1.2A series).

Q: Do the transformers have the same physical footprint?

A: Yes. Both units share identical dimensions: 79.38mm length, 52.39mm width, and 68.26mm maximum seated height. Chassis mount orientation and mounting interface are identical, enabling direct mechanical substitution in existing designs.

Q: What is the difference between the 6495-036 and 6495R-036?

A: The primary differences are product status and regulatory compliance. The 6495-036 is obsolete and non-RoHS compliant. The 6495R-036 is an active product with RoHS3 compliance. All electrical and mechanical parameters are equivalent.

Q: Can the 6495R-036 replace the 6495-036 in existing equipment?

A: Yes. The 6495R-036 is a direct functional equivalent with identical electrical ratings, winding configurations, and physical dimensions. It is suitable for field replacement and retrofit applications.

Q: Are both termination styles available on the 6495R-036?

A: Yes. The 6495R-036 supports both solder and quick connect termination options, matching the termination flexibility of the 6495-036.

Q: Does the 6495R-036 maintain the same isolation voltage rating?
