SCRN233R Film Capacitor Equivalent & Substitute Parts

Part Overview

The SCRN233R is a 1 µF film capacitor rated for 1000Vpk AC operation, manufactured by Cornell Dubilier Electronics (CDE). This radial, can-style component 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 active equivalent parts essential for ongoing system support and procurement planning. Substitute parts must maintain identical electrical performance and mechanical compatibility to ensure reliable operation in commutation, high-frequency switching, and high-pulse DV/DT applications.

Substitute Part Grouping Explanation

Substitution of the SCRN233R is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must satisfy the following criteria:

• Capacitance Value: Exactly 1 µF
• Tolerance: ±10%
• Voltage Rating (AC): 1000Vpk minimum
• Dielectric Type: Paper, Metallized
• Operating Temperature Range: -40°C to +80°C minimum
• Package Style: Radial, Can configuration
• Physical Dimensions: 2.160" L × 1.310" W with 2.190" seated height
• Lead Spacing: 0.810" (20.57mm)
• Termination: Threaded, Male
• Mounting Configuration: Chassis Mount with holder/bracket requirement

The SCRN233R-F meets all substitution criteria and is classified as an active product, providing a direct replacement path for the obsolete SCRN233R.

Engineering Selection Recommendations

The SCRN233R-F is the direct equivalent and recommended substitute for the obsolete SCRN233R. Selection is based on the following engineering factors:

Product Status: The SCRN233R is classified as obsolete, while the SCRN233R-F maintains active product status with current manufacturing support and availability.

Electrical Equivalence: All electrical parameters are identical, including capacitance (1 µF), tolerance (±10%), and voltage rating (1000Vpk AC). The dielectric material (paper, metallized) and operating temperature range (-40°C to +80°C) are unchanged.

Mechanical Compatibility: Physical dimensions, lead spacing, termination type, and mounting configuration are identical. The SCRN233R-F will function as a direct drop-in replacement in existing chassis mount applications using holder/bracket assemblies.

Regulatory Compliance: The SCRN233R-F achieves ROHS3 compliance, providing improved environmental and regulatory standing compared to the non-compliant SCRN233R. Both parts maintain REACH Unaffected status.

Application Suitability: The substitute part is suitable for commutation, high-frequency switching, and high-pulse DV/DT applications without modification to circuit design or board layout.

Frequently Asked Questions (FAQ)

Q: Can the SCRN233R-F be used as a direct replacement for the SCRN233R?

A: Yes. The SCRN233R-F is electrically and mechanically identical to the SCRN233R across all specified parameters. It functions as a direct drop-in substitute with no circuit modifications required.

Q: What is the difference between SCRN233R and SCRN233R-F?

A: The primary differences are product status and regulatory compliance. The SCRN233R is obsolete, while the SCRN233R-F is an active product. The SCRN233R-F achieves ROHS3 compliance, whereas the SCRN233R is RoHS non-compliant. All electrical and mechanical specifications are identical.

Q: Are the physical dimensions and lead spacing identical?

A: Yes. Both parts share identical dimensions (2.160" L × 1.310" W, 54.86mm × 33.27mm), seated height (2.190" / 55.63mm), and lead spacing (0.810" / 20.57mm). The SCRN233R-F will fit existing mounting brackets and holders without modification.

Q: What mounting configuration is required for these capacitors?

A: Both the SCRN233R and SCRN233R-F are chassis mount components that require a holder or bracket assembly. They are not surface-mount or through-hole components suitable for direct PCB mounting.

Q: Are there any temperature or voltage derating considerations?

A: No derating differences exist between the two parts. Both operate across the identical temperature range (-40°C to +80°C) and are rated for 1000Vpk AC operation.

Q: What applications are these capacitors suitable for?

A: Both parts are specified for commutation, high-frequency switching, and high-pulse DV/DT applications. The paper metallized dielectric construction supports these demanding electrical environments.

Q: Is the SCRN233R-F available in different packaging options?

A: The SCRN233R-F is supplied in bulk packaging, while the SCRN233R was supplied with standard packaging. Both use identical radial can-style package construction.
