167334J63A-F Equivalent & Substitute Parts

Part Overview

The 167334J63A-F is a 0.33 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE), designed for general-purpose applications requiring reliable capacitance stability and low dielectric loss. This radial through-hole component operates across a temperature range of -55°C to 125°C with a ±5% capacitance tolerance. As an active product with 1011 units in stock, the availability of alternative components may be necessary to accommodate supply chain variability, specific lead spacing requirements, or higher voltage margin applications.

Substitute Part Grouping Explanation

Substitution of the 167334J63A-F is permissible based on the following electrical and mechanical criteria:

Critical Parameters for Substitution:

Capacitance value must remain 0.33 µF
Voltage rating must be equal to or greater than 63V DC / 40V AC
Tolerance specification must be ±5% or tighter
Operating temperature range must encompass -55°C to 125°C
Mounting type must remain through-hole radial configuration
Termination must remain PC Pins

Lead Spacing Considerations: While lead spacing variation is acceptable within PCB layout constraints, substitutes with different lead spacing (5.00mm vs. 7.50mm) require board redesign validation.

Dielectric Material: Polyester-based dielectrics (including Polyethylene Terephthalate metallized variants) are functionally equivalent for general-purpose applications.

Engineering Selection Recommendations

Primary Equivalent (Same Electrical Specifications):

168334J63H-F (Cornell Dubilier Electronics): Maintains identical electrical ratings and operating characteristics. Inventory availability is higher at 6053 units. Lead spacing differs (5.00mm vs. 7.50mm), requiring PCB layout verification prior to implementation.

Upgraded Voltage Rating Option:

B32520C1334J000 (EPCOS - TDK Electronics): Exceeds voltage requirements with 100V DC / 63V AC rating, providing enhanced voltage margin. Largest inventory stock at 57810 units. Meets AEC-Q200 automotive qualification. Dimensions vary, requiring clearance validation. Lead spacing matches original component (7.50mm).

Compact Alternative (Reduced Footprint):

B32529C0334J000 / B32529C0334J289 (EPCOS - TDK Electronics): Electrically equivalent at 63V DC / 40V AC. Both variants feature smaller footprint (7.30mm x 3.00mm vs. 10.50mm x 3.50mm) and reduced height (6.50mm vs. 7.00mm). Lead spacing is 5.00mm. B32529C0334J289 is supplied in Cut Tape packaging. Both meet AEC-Q200 automotive qualification standards. Combined inventory of 15,499 units.

All substitute parts maintain ROHS3 compliance, equivalent operating temperature range, and ±5% capacitance tolerance.

Frequently Asked Questions (FAQ)

Q: Can B32520C1334J000 replace the 167334J63A-F directly? A: Yes, electrically. The B32520C1334J000 is functionally equivalent with superior voltage margin (100V DC vs. 63V DC). However, physical dimensions differ (10.00mm x 4.00mm vs. 10.50mm x 3.50mm), and height is greater (8.50mm vs. 7.00mm). Lead spacing matches at 7.50mm. Verify PCB clearance before deployment.

Q: What is the difference between B32529C0334J000 and B32529C0334J289? A: These parts are electrically and mechanically identical. The primary distinction is packaging: B32529C0334J000 is supplied in Bulk configuration, while B32529C0334J289 is supplied in Cut Tape format. Select based on assembly process requirements.

Q: Can I use 168334J63H-F as a drop-in replacement? A: Electrically yes—identical voltage, capacitance, and tolerance. However, lead spacing is 5.00mm (vs. 7.50mm original), and height is increased to 7.50mm. PCB layout modification is required to accommodate the different lead pitch.

Q: Why would I choose a substitute over the original 167334J63A-F? A: Substitutes provide alternative options based on supply availability, specific voltage margin requirements, dimensional constraints, or packaging preferences. B32520C1334J000 offers higher voltage rating; the 168334J63H-F and B32529 variants provide compact footprints; B32529C0334J289 provides tape packaging for automated assembly.

Q: Are all substitutes ROHS3 compliant? A: Yes. All listed components, including the 167334J63A-F and all substitutes, meet ROHS3 compliance requirements.

Q: Do the substitute parts meet automotive standards? A: The EPCOS - TDK Electronics variants (B32520C1334J000, B32529C0334J000, and B32529C0334J289) carry AEC-Q200 qualification for automotive applications. The Cornell Dubilier variants do not specify automotive qualification.
