SCRN224R Film Capacitor Equivalent & Substitute Parts

Part Overview

The SCRN224R is a 10 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 600Vpk AC operation with paper metallized dielectric construction. This component is designed for radial, chassis-mount applications requiring threaded male termination and is classified as obsolete in current product lines.

The necessity to identify substitute parts arises from the obsolete status of the SCRN224R. While inventory remains available, long-term procurement reliability and compliance with modern regulatory standards require evaluation of active alternative components that maintain electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the SCRN224R is determined by strict equivalence across all electrical and mechanical parameters. The following criteria establish valid substitute relationships:

Electrical Equivalence Requirements:

• Capacitance value: 10 µF (exact match)
• Tolerance: ±10% (exact match)
• Voltage rating (AC): 600Vpk (exact match or higher)
• Dielectric material: Paper, Metallized (exact match)
• Operating temperature range: -40°C to 80°C minimum (exact match or wider range)

Mechanical Equivalence Requirements:

• Package type: Radial, Can (exact match)
• Mounting configuration: Chassis Mount, Requires Holder/Bracket (exact match)
• Termination: Threaded, Male (exact match)
• Physical dimensions: 2.910" L × 1.910" W (73.91mm × 48.51mm) with 4.310" (109.47mm) maximum seated height (exact match)
• Lead spacing: 1.380" (35.05mm) (exact match)

Substitute parts must satisfy all criteria listed above to ensure direct compatibility without circuit board redesign, mechanical rework, or application performance degradation.

Parameter Comparison

Engineering Selection Recommendations

The SCRN224R-F is a direct electrical and mechanical equivalent to the SCRN224R. Both components are manufactured by Cornell Dubilier Electronics within the SCR series and share identical specifications across all functional parameters: 10 µF capacitance, ±10% tolerance, 600Vpk AC rating, paper metallized dielectric, and identical physical dimensions and termination configuration.

The primary distinction between these components is product status and regulatory compliance. The SCRN224R is classified as obsolete, while the SCRN224R-F maintains active product status. Additionally, the SCRN224R-F achieves ROHS3 compliance, whereas the SCRN224R is RoHS non-compliant.

For new designs or long-term procurement strategies, the SCRN224R-F is the appropriate selection due to its active status and modern regulatory compliance. For existing applications currently using the SCRN224R, direct substitution with the SCRN224R-F requires no circuit modifications, mechanical rework, or performance re-evaluation, as all electrical and mechanical parameters remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can the SCRN224R-F be used as a direct replacement for the SCRN224R in existing applications?

A: Yes. The SCRN224R-F is electrically and mechanically identical to the SCRN224R. All electrical parameters (capacitance, tolerance, voltage rating, dielectric material, temperature range) and mechanical parameters (package type, dimensions, lead spacing, termination) are identical. No circuit redesign or mechanical modification is required.

Q: What is the difference between the SCRN224R and SCRN224R-F?

A: The primary differences are product status and regulatory compliance. The SCRN224R is obsolete and RoHS non-compliant. The SCRN224R-F is an active product that achieves ROHS3 compliance. All functional specifications are identical.

Q: Are the physical dimensions and mounting requirements identical?

A: Yes. Both components feature identical radial, can-style packaging with dimensions of 2.910" L × 1.910" W (73.91mm × 48.51mm), maximum seated height of 4.310" (109.47mm), and lead spacing of 1.380" (35.05mm). Both require chassis mount configuration with holder/bracket support and threaded male termination.

Q: What applications are these capacitors suitable for?

A: Both the SCRN224R and SCRN224R-F are rated for commutation, high frequency switching, and high pulse DV/DT applications. The 600Vpk AC rating and paper metallized dielectric construction support these demanding electrical environments.

Q: Is the SCRN224R-F available in the same packaging format?
