• Tolerance: ±10% (exact match required)
• Voltage Rating (AC): 2000Vpk (exact match required)
• Dielectric Material: Paper, Metallized (exact match required)
• Operating Temperature Range: -40°C to 80°C (exact match required)

Mechanical Parameters:

• Package / Case: Radial, Can (exact match required)
• Mounting Type: Chassis Mount, Requires Holder/Bracket (exact match required)
• Termination: Threaded, Male (exact match required)
• Lead Spacing: 2.000" (50.80mm) (exact match required)
• Physical Dimensions: 4.560" L x 3.750" W, Height 5.810" (exact match required)

Application Compatibility:

• Commutation, High Frequency Switching, High Pulse DV/DT (exact match required)

Substitute parts must satisfy all electrical, mechanical, and dimensional requirements without deviation to ensure direct interchangeability in existing circuit designs and mechanical assemblies.

Parameter Comparison

Engineering Selection Recommendations

The SCRN256R-F is a direct electrical and mechanical equivalent to the obsolete SCRN256R. Both components are manufactured by Cornell Dubilier Electronics within the SCR series and satisfy identical specifications across all critical parameters: 10 µF capacitance, ±10% tolerance, 2000Vpk AC voltage rating, paper metallized dielectric, radial can package, and threaded male termination with 2.000" lead spacing.

The primary distinction between these parts is product status and regulatory compliance. The SCRN256R is classified as obsolete, while the SCRN256R-F maintains active product status. Additionally, the SCRN256R-F is ROHS3 compliant, whereas the SCRN256R is RoHS non-compliant. Both components maintain REACH Unaffected status and share identical ECCN (EAR99) and HTSUS (8532.25.0040) classifications.

For new designs, production continuity, and systems requiring regulatory compliance with modern environmental standards, the SCRN256R-F is the appropriate selection. The active product status ensures ongoing availability and manufacturing support. For legacy system maintenance where original specifications must be preserved without modification, the SCRN256R-F provides complete functional and mechanical interchangeability.

Frequently Asked Questions (FAQ)

Q: Can SCRN256R-F be used as a direct replacement for SCRN256R in existing assemblies?

A: Yes. The SCRN256R-F is electrically and mechanically identical to the SCRN256R. Both components feature 10 µF capacitance, ±10% tolerance, 2000Vpk AC rating, paper metallized dielectric, identical physical dimensions (4.560" L x 3.750" W, 5.810" height), 2.000" lead spacing, and threaded male termination. Direct substitution requires no circuit modification or mechanical redesign.

Q: What is the significance of the product status difference between SCRN256R and SCRN256R-F?

A: The SCRN256R is classified as obsolete, indicating discontinued manufacturing and limited availability. The SCRN256R-F maintains active product status, ensuring continued manufacturing, supply chain availability, and technical support from Cornell Dubilier Electronics. For production applications, the active status of SCRN256R-F provides supply security.

Q: How do the RoHS compliance differences affect substitution?

A: The SCRN256R is RoHS non-compliant, while SCRN256R-F is ROHS3 compliant. For applications subject to RoHS3 regulatory requirements or customer specifications mandating RoHS compliance, SCRN256R-F is the required selection. Both components maintain identical REACH Unaffected status.

Q: Are the packaging and mounting requirements identical between these parts?

A: Yes. Both SCRN256R and SCRN256R-F are supplied in radial can packages requiring chassis mount installation with holder/bracket support. Lead spacing, termination type (threaded male), and all physical dimensions are identical, ensuring compatibility with existing mechanical assemblies and PCB layouts.

Q: What applications are these capacitors designed for?

A: Both components are specified for commutation, high frequency switching, and high pulse DV/DT applications. The 2000Vpk AC rating and paper metallized dielectric construction support these demanding electrical environments. Operating temperature range of -40°C to 80°C accommodates industrial and commercial applications.

Q: Is there any performance difference between SCRN256R and SCRN256R-F?

A: No performance difference exists. Both components share identical electrical specifications: 10 µF capacitance, ±10% tolerance, 2000Vpk AC voltage rating, paper metallized dielectric, and -40°C to 80°C operating temperature range. Functional performance in circuit operation is equivalent.
