SCRN242R Film Capacitor Equivalent & Substitute Parts

Part Overview

The SCRN242R is a 2 µF film capacitor rated for 1500Vpk AC operation, manufactured by Cornell Dubilier Electronics (CDE) in the SCR series. This component features paper-metallized dielectric construction in a radial, can-style package with threaded male termination, designed for chassis mount applications requiring a holder or bracket.

The SCRN242R is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing maintenance and repair of legacy equipment utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCRN242R is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 2 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating (AC): 1500Vpk minimum (exact match required)
• Dielectric Material: Paper, Metallized (exact match required)
• Operating Temperature Range: -40°C to 80°C minimum (exact match required)
• Package Configuration: Radial, Can with threaded male termination (exact match required)
• Physical Dimensions: 2.690" L x 1.560" W with 3.560" maximum seated height (exact match required)
• Lead Spacing: 1.250" (31.75mm) (exact match required)

Substitute parts must satisfy all parameters listed above to ensure mechanical fit, electrical performance, and functional compatibility within the original application circuit.

Parameter Comparison

Engineering Selection Recommendations

The SCRN242R-F is a direct electrical and mechanical equivalent to the SCRN242R. Both components are manufactured by Cornell Dubilier Electronics within the SCR series and share identical specifications for capacitance, voltage rating, dielectric material, operating temperature range, package configuration, and physical dimensions.

The primary distinction between these parts is product status and regulatory compliance:

• SCRN242R: Obsolete product status; RoHS non-compliant
• SCRN242R-F: Active product status; ROHS3 compliant

For new designs or equipment requiring regulatory compliance with RoHS3 standards, the SCRN242R-F is the appropriate selection. For legacy equipment repair or maintenance where original specifications must be maintained and RoHS compliance is not a requirement, the SCRN242R remains functionally equivalent.

Both parts carry identical REACH and ECCN classifications, indicating equivalent regulatory treatment for export and environmental compliance purposes.

Frequently Asked Questions (FAQ)

Q: Can SCRN242R-F be used as a direct replacement for SCRN242R in existing equipment?

A: Yes. The SCRN242R-F is electrically and mechanically identical to the SCRN242R. All critical parameters—capacitance, voltage rating, dielectric material, operating temperature range, package type, physical dimensions, and termination style—are equivalent. Direct substitution is permissible without circuit modification.

Q: What is the difference between SCRN242R and SCRN242R-F?

A: The primary differences are product status and regulatory compliance. The SCRN242R is obsolete and RoHS non-compliant, while the SCRN242R-F is an active product with ROHS3 compliance. Electrical and mechanical specifications are identical.

Q: Does the SCRN242R-F require a different mounting bracket or holder?

A: No. Both the SCRN242R and SCRN242R-F are radial, can-style components with identical physical dimensions (2.690" L x 1.560" W, 3.560" maximum height) and lead spacing (1.250"). Existing chassis mount holders and brackets are compatible with both parts.

Q: Are there any thermal or frequency performance differences between these parts?

A: No. Both components operate across the identical temperature range (-40°C to 80°C) and are rated for the same applications: commutation, high frequency switching, and high pulse DV/DT environments. Performance characteristics are equivalent.

Q: What is the significance of the RoHS3 compliance difference?

A: RoHS3 compliance indicates the SCRN242R-F meets current European Union Restriction of Hazardous Substances regulations. The SCRN242R, being obsolete, does not carry this certification. For equipment destined for markets with RoHS compliance requirements, the SCRN242R-F is the appropriate selection.

Q: Can I use SCRN242R-F in high-voltage applications rated for 1500Vpk?

A: Yes. The SCRN242R-F is rated for 1500Vpk AC operation, identical to the SCRN242R. Both components are suitable for high-voltage applications within this rating.

Q: Is the lead spacing identical between both parts?

A: Yes. Both the SCRN242R and SCRN242R-F feature 1.250" (31.75mm) lead spacing. PCB layouts and mechanical assemblies designed for one part accommodate the other without modification.
