167334K100C-F Film Capacitor Equivalent and Substitute Parts

Part Overview

The Cornell Dubilier Electronics (CDE) 167334K100C-F is a 0.33 µF film capacitor rated at 100V DC with ±10% tolerance. This polyester, metallized radial capacitor is designed for general-purpose applications with through-hole mounting. The part is currently active in production with 1,178 units in stock. Equivalent and substitute parts are necessary when the primary part faces extended lead times, obsolescence concerns, or when design specifications allow for tolerance improvements or voltage derating optimization.

Substitute Part Grouping Explanation

Substitution for the 167334K100C-F is determined by strict equivalence in the following critical parameters: capacitance value (0.33 µF), voltage rating (minimum 100V DC), dielectric material type (polyester-based, metallized), mounting type (through-hole radial), and lead spacing (0.295" / 7.50mm). All substitute parts must meet or exceed the DC voltage rating and maintain the same capacitance value within the allowed tolerance band. Tolerance improvements (from ±10% to ±5%) and physical dimension variations are allowable provided lead spacing and mounting footprint compatibility are preserved.

The substitute parts are grouped as follows:

• Tolerance upgrade substitutes: Parts with ±5% tolerance maintaining identical capacitance and voltage ratings
• Direct equivalents across manufacturers: Parts with matching electrical and mechanical specifications from alternative manufacturers

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active production status with ROHS3 compliance and REACH unaffected designation, ensuring regulatory acceptance across markets. The 167334J100C-F offers a tolerance upgrade to ±5% within the same manufacturer (Cornell Dubilier Electronics) with identical physical dimensions and electrical ratings, providing improved capacitance stability without design modification requirements.

The EPCOS B32520C1334K000 serves as a direct equivalent with ±10% tolerance, maintaining electrical and mechanical compatibility while offering significantly higher inventory availability (3,062 units). The B32520C1334J000 combines both tolerance upgrade (±5%) and extended inventory (57,810 units), with AEC-Q200 automotive qualification providing additional assurance for critical applications. Physical dimensions vary slightly between manufacturers (CDE: 0.413" L × 0.197" W versus EPCOS: 0.394" L × 0.157" W with corresponding height differences), but lead spacing remains constant at 0.295" (7.50mm), ensuring PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 167334J100C-F directly replace the 167334K100C-F? A: Yes. The 167334J100C-F is a direct substitute with identical electrical specifications and physical dimensions. The ±5% tolerance is tighter than the ±10% of the original part, providing superior capacitance accuracy with no design modifications required.

Q: What is the primary difference between the CDE and EPCOS substitute options? A: Both manufacturers provide equivalent electrical performance at identical voltage and capacitance ratings. Physical dimensions differ slightly; CDE parts measure 0.413" × 0.197" while EPCOS measures 0.394" × 0.157". Lead spacing is identical at 0.295" (7.50mm), confirming PCB footprint compatibility.

Q: Is the EPCOS B32520C1334K000 suitable for automotive applications? A: The B32520C1334K000 meets automotive EMI/RFI suppression application requirements and is rated for general automotive use. The higher-grade B32520C1334J000 carries AEC-Q200 qualification for enhanced automotive reliability.

Q: Will the ±5% tolerance upgrade affect circuit performance? A: The ±5% tolerance parts (167334J100C-F and B32520C1334J000) reduce capacitance variance compared to ±10% parts. This improvement benefits circuits requiring precise capacitance values, particularly in timing, filtering, or tuning applications.

Q: Are there physical size constraints with EPCOS substitutes? A: EPCOS parts are physically smaller (0.394" × 0.157" versus 0.413" × 0.197"), with a maximum height of 0.335" compared to 0.433". Lead spacing remains constant at 7.50mm, allowing direct PCB footprint reuse. Verify clearance around component mounting areas if space constraints exist.

Q: Which substitute offers the best availability? A: The EPCOS B32520C1334J000 provides the highest inventory at 57,810 units, combined with ±5% tolerance and AEC-Q200 rating, making it the optimal choice for high-volume production requiring assured supply and enhanced specifications.
