SCRN227R Film Capacitor Equivalent & Substitute Parts

Part Overview

The SCRN227R is a 20 µF film capacitor rated for 600Vpk AC operation, manufactured by Cornell Dubilier Electronics (CDE). This radial, can-style capacitor features paper-metallized dielectric construction and is designed for chassis mount applications requiring a holder or bracket. The part is classified as obsolete, making identification of suitable substitutes necessary for ongoing system maintenance and repair operations. The SCRN227R is specified for commutation, high-frequency switching, and high pulse DV/DT applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCRN227R is determined by electrical and mechanical parameter equivalence. The critical parameters governing substitution are:

Electrical Parameters:

• Capacitance value: 20 µF
• Tolerance: ±10%
• Voltage rating (AC): 600Vpk
• Dielectric material: Paper, Metallized
• Operating temperature range: -40°C to 80°C

Mechanical Parameters:

• Package type: Radial, Can
• Mounting configuration: Chassis Mount, Requires Holder/Bracket
• Physical dimensions: 3.660" L x 1.970" W (92.96mm x 50.04mm), Lip
• Height (seated, max): 5.810" (147.57mm)
• Termination: Threaded, Male
• Lead spacing: 1.380" (35.05mm)

A substitute part must match all electrical parameters and maintain mechanical compatibility with existing mounting infrastructure and circuit board layouts. The SCRN227R-F meets these criteria as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The SCRN227R-F is a direct electrical and mechanical equivalent to the SCRN227R. Both parts are manufactured by Cornell Dubilier Electronics within the SCR series and share identical capacitance, voltage rating, dielectric composition, temperature range, and physical form factor.

The primary distinction between the two parts is product status and regulatory compliance. The SCRN227R is classified as obsolete, while the SCRN227R-F maintains active product status. The SCRN227R-F achieves ROHS3 compliance, whereas the SCRN227R is RoHS non-compliant. Both parts maintain REACH Unaffected status.

For new designs and ongoing system support where regulatory compliance is required, the SCRN227R-F is the appropriate selection. For legacy system maintenance where the original SCRN227R is specified, the SCRN227R-F provides full functional and mechanical compatibility without circuit modification or holder/bracket redesign.

Frequently Asked Questions (FAQ)

Q: Can the SCRN227R-F be used as a direct replacement for the SCRN227R?

A: Yes. The SCRN227R-F is electrically and mechanically equivalent to the SCRN227R. Both parts have identical capacitance (20 µF), tolerance (±10%), voltage rating (600Vpk AC), dielectric material (paper, metallized), operating temperature range (-40°C to 80°C), and physical dimensions. The SCRN227R-F will function identically in circuits designed for the SCRN227R without modification to mounting hardware or circuit board layout.

Q: What is the difference between the SCRN227R and SCRN227R-F?

A: The SCRN227R and SCRN227R-F are identical in electrical performance and mechanical form factor. The SCRN227R is classified as obsolete, while the SCRN227R-F is an active product. The SCRN227R-F achieves ROHS3 compliance, whereas the SCRN227R does not. Both parts are REACH Unaffected.

Q: Are there any packaging differences between these parts?

A: The SCRN227R and SCRN227R-F share the same radial, can-style package with identical physical dimensions (3.660" L x 1.970" W, 92.96mm x 50.04mm), maximum seated height (5.810" or 147.57mm), lead spacing (1.380" or 35.05mm), and threaded male termination. Both require chassis mount holders or brackets. The SCRN227R-F is supplied in bulk packaging, while the SCRN227R packaging specification is not detailed.

Q: Can these capacitors be used in high-frequency switching applications?

A: Yes. Both the SCRN227R and SCRN227R-F are specified for high-frequency switching, high pulse DV/DT, and commutation applications. The paper-metallized dielectric construction and 600Vpk AC rating support these operating conditions within the -40°C to 80°C temperature range.

Q: What mounting considerations apply to these capacitors?

A: Both the SCRN227R and SCRN227R-F are chassis mount components that require a holder or bracket for mechanical support. The threaded male termination and radial can configuration necessitate proper mounting infrastructure. Physical dimensions and lead spacing are identical between the two parts, ensuring compatibility with existing mounting systems.

Q: Is the SCRN227R-F suitable for applications requiring RoHS compliance?

A: Yes. The SCRN227R-F is ROHS3 compliant. If your application or regulatory environment requires RoHS compliance, the SCRN227R-F is the appropriate selection. The original SCRN227R is RoHS non-compliant.
