Frequently Asked Questions (FAQ)

Q: Can the SCRN246R-F be used as a direct replacement for the SCRN246R without any circuit modifications?

A: Yes. The SCRN246R-F is electrically and mechanically identical to the SCRN246R across all specified parameters, including capacitance, voltage rating, dielectric material, operating temperature range, package type, mounting configuration, and termination style. No circuit modifications are required.

Q: What is the difference between the SCRN246R and SCRN246R-F?

A: The primary differences are product status and regulatory compliance. The SCRN246R is obsolete and RoHS non-compliant, while the SCRN246R-F is an active product with ROHS3 compliance. All electrical and mechanical specifications are identical.

Q: Are the physical dimensions and mounting requirements identical between these parts?

A: Yes. Both parts share identical dimensions (2.160" L × 1.310" W, 54.86mm × 33.27mm with lip; height 2.190" or 55.63mm), lead spacing (0.810" or 20.57mm), mounting type (chassis mount requiring holder/bracket), and threaded male termination. No mechanical redesign is necessary.

Q: What applications are these capacitors suitable for?

A: Both the SCRN246R and SCRN246R-F are rated for commutation, high frequency switching, and high pulse DV/DT applications. The 2000Vpk AC rating and paper metallized dielectric support these demanding electrical environments.

Q: Is the SCRN246R-F available in the same packaging as the SCRN246R?

A: Both parts use identical radial can package configurations. The SCRN246R-F is supplied in bulk packaging, while the SCRN246R packaging specification was not detailed in the provided data.

Q: What is the operating temperature range for these capacitors?

A: Both the SCRN246R and SCRN246R-F operate across an identical temperature range of -40°C to +80°C, ensuring consistent performance across standard industrial and commercial environments.

Q: Why should I select the SCRN246R-F over the SCRN246R?

A: The SCRN246R-F should be selected because it is an active product with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The SCRN246R is obsolete, presenting supply chain risk. All electrical and mechanical performance characteristics are equivalent.
