SCRN241R Film Capacitor Equivalent & Substitute Parts

Part Overview

The SCRN241R is a 1 µF film capacitor rated for 1500Vpk AC operation, manufactured by Cornell Dubilier Electronics (CDE) in the SCR series. This component features a paper metallized dielectric with radial, can-style packaging and threaded male termination for chassis mount applications requiring a holder or bracket.

The SCRN241R is classified as obsolete. Locating equivalent substitute parts is necessary to support ongoing maintenance, repair, and production requirements for legacy equipment utilizing this component. Active production alternatives with identical electrical and mechanical specifications are available.

Mechanical Parameters:

• Package / Case: Radial, Can
• Mounting Type: Chassis Mount, Requires Holder/Bracket
• Physical Dimensions: 2.160" L × 1.310" W (54.86mm × 33.27mm), Lip
• Height (Seated, Max): 2.940" (74.68mm)
• Termination Type: Threaded, Male
• Lead Spacing: 0.810" (20.57mm)

Application Compatibility:

• Commutation; High Frequency, Switching; High Pulse, DV/DT

The SCRN241R-F is identified as a direct equivalent substitute, manufactured by the same supplier (Cornell Dubilier Electronics) within the same SCR series, with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The SCRN241R-F is a direct functional and mechanical equivalent to the SCRN241R. Selection between these parts is determined by product status and regulatory compliance requirements:

SCRN241R-F is the recommended selection for new designs, production restocking, and applications where regulatory compliance is required. This part is in active production status and meets ROHS3 compliance standards, providing assurance of continued availability and regulatory alignment.

SCRN241R remains applicable for legacy equipment repair and maintenance where existing inventory is available and RoHS non-compliance does not present a constraint. However, given the obsolete status of SCRN241R, transition to SCRN241R-F is advised for long-term supply chain stability.

Both parts are manufactured by Cornell Dubilier Electronics within the SCR series and share identical electrical performance characteristics, mechanical dimensions, and application suitability for commutation, high frequency switching, and high pulse DV/DT circuits.

Frequently Asked Questions (FAQ)

Q: Can SCRN241R-F be used as a direct replacement for SCRN241R in existing equipment?

A: Yes. The SCRN241R-F is electrically and mechanically identical to SCRN241R. All electrical parameters (1 µF capacitance, ±10% tolerance, 1500Vpk AC rating), physical dimensions (2.160" L × 1.310" W, 2.940" height), termination type (threaded male), and lead spacing (0.810") are identical. Direct substitution is supported without circuit modification or mechanical redesign.

Q: What is the difference between SCRN241R and SCRN241R-F?

A: The primary differences are product status and regulatory compliance. SCRN241R is obsolete and RoHS non-compliant. SCRN241R-F is in active production and ROHS3 compliant. All electrical and mechanical specifications are identical.

Q: Why is SCRN241R obsolete?

A: The SCRN241R has been discontinued by Cornell Dubilier Electronics. The SCRN241R-F serves as the active production equivalent within the SCR series.

Q: Does the SCRN241R-F require the same mounting bracket or holder as the SCRN241R?

A: Yes. Both parts are chassis mount components requiring a holder or bracket. Physical dimensions and termination type are identical, ensuring compatibility with existing mounting hardware.

Q: Are there any performance differences between SCRN241R and SCRN241R-F in high frequency or high pulse applications?

A: No. Both parts are rated for identical applications: commutation, high frequency switching, and high pulse DV/DT circuits. Operating temperature range (-40°C to 80°C) and dielectric material (paper, metallized) are identical.

Q: What is the lead spacing for these capacitors?

A: The lead spacing is 0.810" (20.57mm) for both SCRN241R and SCRN241R-F.

Q: Can SCRN241R-F be used in applications requiring RoHS compliance?

A: Yes. SCRN241R-F is ROHS3 compliant and suitable for applications with RoHS requirements. SCRN241R is RoHS non-compliant and not suitable for such applications.
