Key Parameters

Substitute Part Grouping Explanation

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

Mandatory Equivalence Parameters:

• Capacitance: 0.33 µF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage Rating - DC: 63V minimum (equal or higher acceptable)
• Dielectric Material: Polyester, Metallized (composition match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Lead Spacing: 0.197 inches / 5.00 mm (exact match required)
• Termination: PC Pins (exact match required)
• RoHS Status: ROHS3 Compliant (compliance match required)

Acceptable Variation Parameters:

• Packaging format (Tape & Reel, Bulk, Cut Tape) — does not affect electrical performance
• Physical dimensions (length, width, height) — minor variations acceptable within radial package constraints
• Manufacturer — alternative qualified manufacturers acceptable
• Series designation — internal manufacturer classification

Substitution Categories:

Direct Equivalents (Same Voltage Rating): Parts maintaining 63V DC rating with identical electrical specifications and interchangeable physical footprint.

Upgrade Substitutes (Higher Voltage Rating): Parts with 100V DC rating providing enhanced voltage margin while maintaining all other electrical and mechanical parameters.

Engineering Selection Recommendations

Direct Equivalent Selection (168334J63H-F):

The 168334J63H-F from Cornell Dubilier Electronics is a direct electrical and mechanical equivalent to the 185334J63RHB-F. The primary difference is packaging format: the substitute is supplied in Bulk packaging rather than Tape & Reel. This part maintains identical voltage ratings, capacitance, tolerance, temperature range, and physical footprint. Selection of this part is appropriate when Bulk packaging is acceptable for assembly processes.

Direct Equivalent Selection (B32529C0334J000 and B32529C0334J289):

Both EPCOS - TDK Electronics parts (B32529C0334J000 in Bulk and B32529C0334J289 in Cut Tape) are direct electrical equivalents with identical 63V DC ratings and 0.33 µF capacitance. These parts feature polyester PET metallized stacked construction and carry AEC-Q200 automotive qualification. Physical dimensions show minor variations within acceptable radial package tolerances. These parts are suitable for applications requiring automotive-grade components or alternative manufacturer sourcing.

Upgrade Selection (B32529C1334J000):

The B32529C1334J000 provides an upgraded voltage rating of 100V DC while maintaining all other electrical specifications. This part is appropriate for applications requiring enhanced voltage margin or where circuit design permits higher voltage-rated components. The increased voltage rating does not affect capacitance, tolerance, temperature range, or mechanical compatibility. This part carries AEC-Q200 automotive qualification and ROHS3 compliance.

All substitute parts maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory conformance.

Frequently Asked Questions (FAQ)

Q: Can I substitute 168334J63H-F for 185334J63RHB-F in automated assembly?

A: The 168334J63H-F is electrically and mechanically equivalent but supplied in Bulk packaging rather than Tape & Reel. Automated pick-and-place assembly typically requires Tape & Reel format. Manual assembly or tape conversion processes would be required.

Q: What is the difference between the CDE and EPCOS parts?

A: Both manufacturers produce equivalent 0.33 µF 63V radial film capacitors with identical electrical performance and physical footprint. The EPCOS parts feature polyester PET metallized stacked construction and carry AEC-Q200 automotive qualification. Selection depends on manufacturer preference, supply chain requirements, and application specifications.

Q: Can I use B32529C1334J000 (100V) instead of the 63V rated part?

A: Yes. The B32529C1334J000 maintains identical capacitance, tolerance, temperature range, and mechanical compatibility while providing a higher voltage rating. Higher voltage-rated capacitors are electrically compatible with circuits designed for lower voltage ratings. This substitution is appropriate when enhanced voltage margin is beneficial or when circuit design permits higher voltage components.

Q: Are there physical dimension differences between these parts?

A: Minor variations exist within radial package constraints. The main part and 168334J63H-F share identical dimensions (0.283" L x 0.138" W, 0.295" height). The EPCOS parts show slightly different dimensions (0.287" L x 0.118" W for 63V versions, 0.287" L x 0.138" W for 100V version). All parts maintain the same 0.197" (5.00 mm) lead spacing and fit standard PCB footprints designed for 5mm radial capacitors.

Q: What packaging formats are available?

A: The 185334J63RHB-F is supplied in Tape & Reel format for automated assembly. Substitute parts are available in Tape & Reel (168334J63H-F equivalent not listed), Bulk, and Cut Tape formats. Packaging selection depends on assembly process requirements and order quantities.

Q: Are all these parts RoHS compliant?

A: Yes. All listed parts maintain ROHS3 compliance and are suitable for applications requiring RoHS-compliant components.
