SCRN236R Film Capacitor Equivalent & Substitute Parts

Part Overview

The SCRN236R is a 5 µF film capacitor rated at 1000Vpk (1KVPK) with paper metallized dielectric, manufactured by Cornell Dubilier Electronics (CDE). This component is designed for commutation, high frequency switching, and high pulse DV/DT applications in chassis mount configurations requiring a holder or bracket.

The SCRN236R 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 operations for legacy equipment utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCRN236R is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 5 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage rating (AC): 1000Vpk (1KVPK) (exact match required)
• Dielectric material: Paper, Metallized (exact match required)
• Operating temperature range: -40°C to 80°C (exact match or better required)

Mechanical Parameters:

• Package type: Radial, Can (exact match required)
• Mounting configuration: Chassis Mount, Requires Holder/Bracket (exact match required)
• Physical dimensions: 2.690" L x 1.560" W (68.33mm x 39.62mm), Lip (exact match required)
• Height (seated, max): 4.310" (109.47mm) (exact match required)
• Termination: Threaded, Male (exact match required)
• Lead spacing: 1.250" (31.75mm) (exact match required)

A substitute part must match all electrical and mechanical parameters listed above to ensure functional and physical compatibility within the original application circuit and mechanical assembly.

Parameter Comparison

Engineering Selection Recommendations

The SCRN236R-F is a direct substitute for the obsolete SCRN236R. Both components are manufactured by Cornell Dubilier Electronics within the SCR series and share identical electrical and mechanical specifications across all critical parameters.

Selection Basis:

The SCRN236R-F is classified as Active product status, ensuring ongoing availability and supply chain support compared to the obsolete SCRN236R. This substitution maintains full functional and physical compatibility for commutation, high frequency switching, and high pulse DV/DT applications.

The SCRN236R-F achieves ROHS3 compliance, whereas the original SCRN236R is RoHS non-compliant. Both components maintain identical REACH Unaffected and EAR99 ECCN classifications. The substitution does not introduce regulatory or compliance conflicts for applications previously using the SCRN236R.

All electrical parameters (5 µF capacitance, ±10% tolerance, 1000Vpk AC rating, paper metallized dielectric, -40°C to 80°C operating range) and mechanical parameters (radial can package, chassis mount configuration, 2.690" x 1.560" dimensions, 4.310" seated height, threaded male termination, 1.250" lead spacing) are identical between the main part and substitute.
