SCRN210R Film Capacitor Equivalent & Substitute Parts

Part Overview

The SCRN210R is a 50 µF film capacitor rated at 200Vpk, manufactured by Cornell Dubilier Electronics (CDE) in the SCR series. This component is designed for applications requiring commutation, high-frequency switching, and high pulse DV/DT performance. The part features a paper metallized dielectric with radial, can-style packaging and threaded male termination for chassis mount installation.

The SCRN210R is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing maintenance and production requirements for legacy systems utilizing this component.

• Voltage Rating (AC): 200Vpk
• Dielectric Material: Paper, Metallized
• Operating Temperature Range: -40°C to 80°C

Mechanical Parameters (Must Match Exactly):

• Package / Case: Radial, Can
• Mounting Type: Chassis Mount, Requires Holder/Bracket
• Physical Dimensions: 3.660" L x 1.970" W (92.96mm x 50.04mm), Lip
• Height - Seated (Max): 5.810" (147.57mm)
• Lead Spacing: 1.380" (35.05mm)
• Termination: Threaded, Male

Application Compatibility:

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

Substitute parts must satisfy all parameters listed above without deviation. The SCRN210R-F meets these criteria and is identified as a direct equivalent.

Engineering Selection Recommendations

The SCRN210R-F is a direct functional and mechanical equivalent to the SCRN210R. Selection between these parts is based on the following engineering considerations:

Product Status: The SCRN210R is obsolete, while the SCRN210R-F is active. For new designs, ongoing production, or long-term supply chain planning, the SCRN210R-F is the appropriate selection.

Regulatory Compliance: The SCRN210R-F is ROHS3 compliant, whereas the SCRN210R is RoHS non-compliant. Applications subject to RoHS regulations or requiring compliance documentation must use the SCRN210R-F.

Electrical and Mechanical Equivalence: All electrical parameters (capacitance, tolerance, voltage rating, dielectric material, temperature range) and mechanical parameters (dimensions, termination, lead spacing, mounting configuration) are identical between both parts. Direct substitution is electrically and mechanically valid.

Availability: The SCRN210R-F is available in active inventory (667 Pcs) with bulk packaging options, ensuring supply continuity compared to the obsolete SCRN210R.

Frequently Asked Questions (FAQ)

Q: Can the SCRN210R-F be used as a direct replacement for the SCRN210R in existing designs?

A: Yes. The SCRN210R-F is electrically and mechanically identical to the SCRN210R. All electrical parameters (50 µF, ±10%, 200Vpk, paper metallized dielectric, -40°C to 80°C operating range) and mechanical parameters (radial can package, threaded male termination, 3.660" x 1.970" dimensions, 1.380" lead spacing) are identical. Direct substitution is valid without circuit or mechanical redesign.

Q: What is the difference between SCRN210R and SCRN210R-F?

A: The primary differences are product status and regulatory compliance. The SCRN210R is obsolete and RoHS non-compliant. The SCRN210R-F is active and ROHS3 compliant. Both parts are functionally and mechanically equivalent.

Q: Are there any packaging differences between SCRN210R and SCRN210R-F?

A: The SCRN210R-F is supplied in bulk packaging, while the SCRN210R packaging specification is not provided. Both parts use identical radial can package configurations with threaded male termination and identical physical dimensions.

Q: Does the SCRN210R-F require a holder or bracket for installation?

A: Yes. The SCRN210R-F, like the SCRN210R, is a chassis mount component that requires a holder or bracket for installation. The mounting configuration and mechanical interface are identical between both parts.

Q: What applications are these capacitors suitable for?

A: Both the SCRN210R and SCRN210R-F are designed for commutation, high-frequency switching, and high pulse DV/DT applications. The 50 µF capacitance, 200Vpk rating, and paper metallized dielectric support these performance requirements.

Q: Is the SCRN210R-F suitable for applications requiring RoHS compliance?

A: Yes. The SCRN210R-F is ROHS3 compliant and is suitable for applications subject to RoHS regulations. The SCRN210R is RoHS non-compliant and should not be used in RoHS-regulated applications.

Q: What is the operating temperature range for these capacitors?

A: Both the SCRN210R and SCRN210R-F operate across a temperature range of -40°C to 80°C. This range applies to all electrical and mechanical specifications.
