Engineering Selection Recommendations

The SCRN253R-F is the direct substitute for the obsolete SCRN253R. Both components are manufactured by Cornell Dubilier Electronics and share identical electrical and mechanical specifications, ensuring form, fit, and function compatibility.

Product Status Consideration: The SCRN253R is classified as obsolete, while the SCRN253R-F maintains active product status. Selection of the SCRN253R-F ensures continued availability and supply chain support for new production and field replacement applications.

Compliance Consideration: The SCRN253R-F is ROHS3 compliant, whereas the SCRN253R is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements mandating RoHS compliance, the SCRN253R-F is the appropriate selection. Both components maintain REACH Unaffected status and share identical ECCN and HTSUS classifications.

Packaging Consideration: The SCRN253R-F is supplied in bulk packaging, while the SCRN253R packaging specification is listed as dash (-). Verify packaging requirements for your procurement and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the SCRN253R-F be used as a direct replacement for the SCRN253R?

A: Yes. The SCRN253R-F is a direct substitute. All electrical parameters (5 µF capacitance, ±10% tolerance, 2000Vpk AC rating, paper metallized dielectric, -40°C to 80°C operating range) and mechanical parameters (radial can package, threaded male termination, 1.380" lead spacing, identical physical dimensions) are identical between the two parts.

Q: What is the primary difference between the SCRN253R and SCRN253R-F?

A: The primary differences are product status and regulatory compliance. The SCRN253R is obsolete and RoHS non-compliant, while the SCRN253R-F is active and ROHS3 compliant. Both components are electrically and mechanically equivalent.

Q: Are there any compatibility concerns when substituting the SCRN253R-F for the SCRN253R?

A: No compatibility concerns exist. Identical lead spacing (1.380"), termination type (threaded male), mounting requirements (chassis mount with holder/bracket), and physical dimensions ensure direct board-level and mechanical compatibility.

Q: Does the SCRN253R-F meet RoHS requirements?

A: Yes. The SCRN253R-F is ROHS3 compliant. If your application or customer requirements mandate RoHS compliance, the SCRN253R-F satisfies this requirement, whereas the SCRN253R does not.

Q: What applications are these capacitors suitable for?

A: Both the SCRN253R and SCRN253R-F are rated for commutation, high frequency switching, and high pulse DV/DT applications. The 2000Vpk AC rating and paper metallized dielectric construction support these demanding electrical environments.

Q: Is the lead spacing identical between the two parts?

A: Yes. Both parts feature 1.380" (35.05mm) lead spacing, ensuring identical PCB footprint and mechanical mounting compatibility.
