SCRN244R Film Capacitor Equivalent & Substitute Parts

Part Overview

The SCRN244R is a 5 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) with a 1500Vpk AC voltage rating, designed for high-frequency switching, commutation, and high pulse applications. The component features a paper metallized dielectric in a radial can configuration with threaded male termination for chassis mount installation.

The SCRN244R carries an obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing maintenance and repair operations for legacy equipment utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCRN244R is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must satisfy the following criteria:

Electrical Parameters (Non-negotiable):

• Capacitance value: 5 µF
• Tolerance: ±10%
• Voltage rating (AC): 1500Vpk minimum
• Dielectric material: Paper, Metallized
• Operating temperature range: -40°C to 80°C minimum

Mechanical Parameters (Non-negotiable):

• Package configuration: Radial, Can
• Mounting type: Chassis Mount, Requires Holder/Bracket
• Termination style: Threaded, Male
• Lead spacing: 1.380" (35.05mm)
• Physical dimensions: 2.910" L x 1.910" W x 5.810" H maximum

Manufacturer Criteria:

• Manufacturer: Cornell Dubilier Electronics (CDE)
• Series: SCR

The SCRN244R-F qualifies as a direct substitute based on complete parameter alignment across all electrical and mechanical specifications.

Engineering Selection Recommendations

SCRN244R-F as Direct Substitute:

The SCRN244R-F is a direct functional and mechanical equivalent to the obsolete SCRN244R. Both components are manufactured by Cornell Dubilier Electronics within the SCR series and share identical electrical specifications (5 µF, ±10% tolerance, 1500Vpk AC rating) and mechanical configurations (radial can package, threaded male termination, identical lead spacing and physical dimensions).

The primary distinction between the two parts is product status and regulatory compliance. The SCRN244R-F maintains active product status with ROHS3 compliance, whereas the SCRN244R is obsolete and RoHS non-compliant. For new designs or equipment requiring regulatory compliance with current environmental standards, the SCRN244R-F is the appropriate selection. For legacy equipment replacement where the original SCRN244R is no longer available, the SCRN244R-F provides complete electrical and mechanical compatibility without design modification.

Both components are suitable for commutation, high-frequency switching, and high pulse/DV/DT applications within the specified operating temperature range of -40°C to 80°C.

Frequently Asked Questions (FAQ)

Q: Can SCRN244R-F be used as a direct replacement for SCRN244R in existing equipment?

A: Yes. The SCRN244R-F is electrically and mechanically identical to the SCRN244R. All electrical parameters (capacitance, voltage rating, tolerance, dielectric material, temperature range) and mechanical specifications (package type, termination style, lead spacing, physical dimensions) are equivalent. No circuit modification or mechanical rework is required for substitution.

Q: What is the difference between SCRN244R and SCRN244R-F?

A: The components are functionally identical. The primary differences are: (1) Product Status—SCRN244R is obsolete while SCRN244R-F is active; (2) RoHS Compliance—SCRN244R is RoHS non-compliant while SCRN244R-F is ROHS3 compliant; (3) Packaging—SCRN244R uses standard packaging while SCRN244R-F is supplied in bulk packaging.

Q: Are there any compatibility concerns when substituting SCRN244R-F for SCRN244R?

A: No compatibility concerns exist. Both components feature identical lead spacing (1.380"), threaded male termination, and radial can package configuration. Installation in existing chassis mount holders/brackets requires no modification.

Q: What applications are these capacitors suitable for?

A: Both SCRN244R and SCRN244R-F are designed for commutation circuits, high-frequency switching applications, and high pulse/DV/DT environments. The 1500Vpk AC voltage rating and paper metallized dielectric support these demanding applications within the -40°C to 80°C operating temperature range.

Q: Why is SCRN244R marked as obsolete?

A: The SCRN244R has reached end-of-life status in the manufacturer's product portfolio. The SCRN244R-F represents the current active equivalent within the SCR series, offering the same electrical and mechanical specifications with updated regulatory compliance.

Q: Can SCRN244R-F be used in new equipment designs?

A: Yes. The SCRN244R-F is an active product with ROHS3 compliance, making it suitable for new equipment designs requiring current environmental and regulatory standards compliance.
