Substitute Part Grouping Explanation

Substitution of the SCRN240R is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications in the following critical areas:

Electrical Parameters:

• Capacitance value: 0.5 µF
• Tolerance: ±10%
• Voltage rating (AC): 1500Vpk (1.5KVPK)
• Dielectric material: Paper, Metallized
• Operating temperature range: -40°C ~ 80°C

Mechanical Parameters:

• Package type: Radial, Can
• Physical dimensions: 2.160" L x 1.310" W (54.86mm x 33.27mm), Lip
• Height - Seated (Max): 2.190" (55.63mm)
• Termination: Threaded, Male
• Lead spacing: 0.810" (20.57mm)
• Mounting configuration: Chassis Mount, Requires Holder/Bracket

Application Compatibility:

• Commutation circuits
• High frequency switching applications
• High pulse, DV/DT environments

The SCRN240R-F is identified as a direct substitute based on complete parameter alignment across all electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The SCRN240R-F is the direct equivalent substitute for the obsolete SCRN240R. Both components are manufactured by Cornell Dubilier Electronics within the SCR series and maintain identical electrical and mechanical specifications.

Primary Advantage of SCRN240R-F:

The SCRN240R-F holds active product status, ensuring continued availability and supply chain reliability. Additionally, the SCRN240R-F achieves ROHS3 compliance, whereas the original SCRN240R is non-compliant. For applications subject to RoHS regulatory requirements or procurement policies mandating RoHS-compliant components, the SCRN240R-F is the appropriate selection.

Both parts maintain identical REACH and ECCN classifications, confirming regulatory equivalence across export and environmental compliance frameworks.

Frequently Asked Questions (FAQ)

Q: Can the SCRN240R-F be used as a direct replacement for the SCRN240R?

A: Yes. The SCRN240R-F is a direct equivalent substitute. All electrical parameters (capacitance, tolerance, voltage rating, dielectric material, operating temperature) and mechanical parameters (package type, dimensions, termination, lead spacing) are identical. Both components are suitable for commutation, high frequency switching, and high pulse DV/DT applications.

Q: What is the primary difference between SCRN240R and SCRN240R-F?

A: The SCRN240R is classified as obsolete, while the SCRN240R-F maintains active product status. Additionally, the SCRN240R-F is ROHS3 compliant, whereas the SCRN240R is non-compliant. All functional and mechanical specifications remain identical.

Q: Are the physical dimensions and mounting requirements identical?

A: Yes. Both the SCRN240R and SCRN240R-F share identical physical dimensions (2.160" L x 1.310" W, 54.86mm x 33.27mm with lip), maximum seated height (2.190" / 55.63mm), lead spacing (0.810" / 20.57mm), and mounting configuration (chassis mount requiring holder/bracket with threaded male termination).

Q: What applications are these capacitors suitable for?

A: Both the SCRN240R and SCRN240R-F are designed for commutation circuits, high frequency switching applications, and high pulse DV/DT environments. The 0.5 µF capacitance with 1500Vpk AC rating and paper metallized dielectric support these demanding electrical conditions.

Q: Is RoHS compliance a factor in selecting between these parts?

A: RoHS compliance becomes a selection factor only if your application, procurement policy, or regulatory environment mandates RoHS-compliant components. The SCRN240R-F is ROHS3 compliant, while the SCRN240R is non-compliant. Functionally and electrically, both parts are equivalent.

Q: What is the lead spacing and how does it affect installation?

A: Both parts feature 0.810" (20.57mm) lead spacing. This spacing is fixed and must be accommodated in the PCB or chassis mounting design. The threaded male termination requires a compatible holder or bracket for secure chassis mounting.

Q: Are there any differences in packaging or inventory status?

A: The SCRN240R is available in 1101 pieces as new original stock. The SCRN240R-F is available in 1144 pieces as new original stock in bulk packaging. Both represent current inventory availability.
