Frequently Asked Questions (FAQ)
Q: Can the 6496R-028 be used as a direct replacement for the 6496-028 in existing designs?
A: Yes. The 6496R-028 maintains identical electrical specifications (80VA, 115V/230V primary, 14V/28V secondary, 5.6A/2.8A output current, 4000Vrms isolation) and mechanical characteristics (chassis mount, solder/quick connect termination, identical dimensions). No circuit modification or mechanical redesign is required.
Q: What is the primary advantage of substituting the 6496-028 with the 6496R-028?
A: The 6496R-028 is an active product with current manufacturing support, whereas the 6496-028 is obsolete. Additionally, the 6496R-028 is ROHS3 compliant, meeting current environmental standards that the 6496-028 does not satisfy.
Q: Are the physical dimensions identical between the two parts?
A: Yes. Both parts share identical dimensions: 63.50mm length, 60.33mm width, and 76.20mm maximum seated height. Mechanical fit in existing chassis designs is equivalent.
Q: Do both parts support the same termination methods?
A: Yes. Both the 6496-028 and 6496R-028 provide solder and quick connect termination options, ensuring compatibility with existing wiring and assembly methods.
Q: What is the isolation voltage rating for these transformers?
A: Both parts provide 4000Vrms isolation voltage, meeting high-voltage isolation requirements in dual-winding configurations.
Q: Are there any differences in the secondary winding configuration?
A: No. Both parts feature dual secondary windings with identical parallel (14V, 5.6A) and series (28V, 2.8A) output configurations.
