Equivalent & Substitute Parts for 185334K63RHB-F

Part Overview

The Cornell Dubilier Electronics (CDE) 185334K63RHB-F is a 0.33 µF film capacitor rated for 63V DC operation with ±10% tolerance, packaged in Tape & Reel format for automated assembly. This radial polyester metallized capacitor operates across the temperature range of -55°C to 125°C and is classified as Active product status with ROHS3 compliance.

Substitute parts are necessary when Tape & Reel packaging is unavailable, when tighter tolerance specifications are required, when higher voltage ratings are needed for circuit margin, or when alternative manufacturer sourcing is required for supply chain continuity.

Substitute Part Grouping Explanation

Substitution logic for the 185334K63RHB-F is based on the following allowed parameters:

Electrical Parameters:

Capacitance value must remain 0.33 µF
DC voltage rating must be 63V or higher
Tolerance may be ±10% or tighter (±5%)
Dielectric material must be polyester metallized construction
Operating temperature range must be -55°C to 125°C or better

Mechanical Parameters:

Mounting type must be Through Hole Radial
Lead spacing must be 0.197" (5.00mm) for PCB hole compatibility
Package/Case must be Radial configuration

Compliance Parameters:

RoHS3 compliance must be maintained
REACH Unaffected status must be preserved

Substitute parts are grouped into three categories: direct equivalents (same electrical and mechanical specifications with different packaging), upgraded tolerance versions (±5% instead of ±10%), and upgraded voltage versions (100V DC instead of 63V DC).

Engineering Selection Recommendations

Direct Equivalents (Same Electrical Specifications):

B32529C0334K000, B32529C0334K189, and B32529C0334K289 are direct electrical equivalents to the 185334K63RHB-F. All three maintain 0.33 µF capacitance, ±10% tolerance, and 63V DC rating. These EPCOS - TDK Electronics parts are manufactured under the B3252* MKT General Purpose series and carry AEC-Q200 automotive qualification. Physical dimensions differ slightly (7.30 x 3.00mm vs. 7.20 x 3.50mm), with reduced height (6.50mm vs. 7.50mm). Lead spacing remains 5.00mm for PCB compatibility. All three are ROHS3 compliant and REACH Unaffected.

Upgraded Tolerance Versions:

168334J63H-F (CDE), B32529C0334J000, and B32529C0334J289 (EPCOS - TDK) provide ±5% tolerance while maintaining 0.33 µF capacitance and 63V DC rating. These parts are suitable when circuit design requires tighter capacitance tolerance. The CDE 168334J63H-F maintains identical physical dimensions to the main part (7.20 x 3.50mm). EPCOS - TDK versions are slightly smaller (7.30 x 3.00mm, 6.50mm height) and carry AEC-Q200 qualification.

Upgraded Voltage Version:

B32529C1334J000 provides 100V DC rating with ±5% tolerance, suitable for applications requiring higher voltage margin. Capacitance remains 0.33 µF. Physical dimensions increase to 7.30 x 3.50mm with 8.00mm height to accommodate the higher voltage rating. This part carries AEC-Q200 qualification and is available in high inventory (55996 Pcs).
