Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 185154J63RCA-F are classified into two categories based on electrical and mechanical compatibility:

Direct Equivalents (Same Electrical Ratings): Parts maintaining identical capacitance (0.15 µF), tolerance (±5%), and voltage rating (63V DC / 40V AC) are classified as direct equivalents. These parts differ only in packaging format (Tape & Reel versus Bulk versus Cut Tape) or series designation. Direct equivalents include 168154J63C-F, B32529C0154J000, and B32529C0154J289.

Upgrade Substitute (Higher Voltage Rating): Part B32529C1154J000 provides a voltage rating upgrade to 100V DC (63V AC) while maintaining the same capacitance and tolerance. This part is suitable for applications requiring higher voltage margin or operating in elevated voltage environments.

Substitution eligibility is determined by the following criteria:

• Capacitance value: 0.15 µF (exact match required)
• Tolerance: ±5% (exact match required)
• Dielectric material: Polyester, Metallized (exact match required)
• Mounting type: Through Hole Radial (exact match required)
• Lead spacing: 0.197" / 5.00mm (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)
• Voltage rating: 63V DC minimum (63V DC direct equivalent or 100V DC upgrade)

Engineering Selection Recommendations

Direct Equivalent Selection (168154J63C-F, B32529C0154J000, B32529C0154J289):

The 168154J63C-F from Cornell Dubilier Electronics maintains identical electrical specifications and physical dimensions to the 185154J63RCA-F, differing only in series designation (168 versus 185) and packaging format (Bulk versus Tape & Reel). This part is suitable for direct substitution in applications where packaging format flexibility is acceptable.

The B32529C0154J000 and B32529C0154J289 from EPCOS - TDK Electronics provide equivalent electrical performance with AEC-Q200 automotive qualification. These parts feature slightly reduced physical dimensions (0.287" L x 0.098" W versus 0.283" L x 0.138" W) and lower seated height (0.256" versus 0.295"), making them suitable for space-constrained PCB layouts. Both parts are ROHS3 compliant and maintain the required operating temperature range. The B32529C0154J289 is supplied in Cut Tape format, while B32529C0154J000 is supplied in Bulk format.

Upgrade Selection (B32529C1154J000):

The B32529C1154J000 provides a voltage rating upgrade to 100V DC (63V AC) while maintaining 0.15 µF capacitance and ±5% tolerance. This part is suitable for applications requiring higher voltage margin, elevated operating environments, or future design revisions with increased voltage requirements. The part carries AEC-Q200 automotive qualification and ROHS3 compliance. Physical dimensions are comparable to other EPCOS B3252* series parts (0.287" L x 0.118" W, 0.256" seated height).

All substitute parts maintain active product status and full regulatory compliance (ROHS3, REACH Unaffected, EAR99 ECCN classification).

Frequently Asked Questions (FAQ)

Q: Can 168154J63C-F be used as a direct replacement for 185154J63RCA-F?

A: Yes. The 168154J63C-F is a direct electrical and mechanical equivalent, maintaining identical capacitance (0.15 µF), tolerance (±5%), voltage rating (63V DC / 40V AC), operating temperature range (-55°C to 125°C), and physical dimensions. The difference is packaging format (Bulk versus Tape & Reel) and series designation. Both parts are manufactured by Cornell Dubilier Electronics and are ROHS3 compliant.

Q: What are the physical dimension differences between CDE and EPCOS B3252 series parts?*

A: The 185154J63RCA-F and 168154J63C-F (CDE) measure 0.283" L x 0.138" W with 0.295" seated height. The EPCOS B32529C0154J000 and B32529C0154J289 measure 0.287" L x 0.098" W with 0.256" seated height. The B32529C1154J000 (100V upgrade) measures 0.287" L x 0.118" W with 0.256" seated height. All parts maintain 0.197" (5.00mm) lead spacing. The EPCOS parts are more compact in width and height, suitable for space-constrained applications.

Q: Are EPCOS B3252 series parts suitable for automotive applications?*

A: Yes. The B32529C0154J000, B32529C0154J289, and B32529C1154J000 carry AEC-Q200 automotive qualification. The 185154J63RCA-F and 168154J63C-F do not list automotive ratings but are suitable for general-purpose applications.

Q: What is the difference between B32529C0154J000 and B32529C0154J289?

A: Both parts are electrically and mechanically identical (0.15 µF, ±5%, 63V DC, -55°C to 125°C). The difference is packaging format: B32529C0154J000 is supplied in Bulk format, while B32529C0154J289 is supplied in Cut Tape (CT) format. Inventory availability differs (3779 pcs Bulk versus 11184 pcs Cut Tape).

Q: When should B32529C1154J000 (100V upgrade) be selected?

A: The B32529C1154J000 should be selected when the application requires higher voltage margin, operates in elevated voltage environments, or when future design revisions may increase voltage requirements. The 100V DC rating provides additional safety margin compared to the 63V DC rating of direct equivalents. All other electrical parameters (capacitance, tolerance, temperature range) remain identical.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed parts (185154J63RCA-F, 168154J63C-F, B32529C0154J000, B32529C0154J289, B32529C1154J000) are ROHS3 compliant and REACH unaffected.

Q: What is the lead spacing for all parts?

A: All parts maintain 0.197" (5.00mm) lead spacing, ensuring PCB footprint compatibility across all substitutes.

Q: Can these parts be used interchangeably in existing designs?

A: Direct equivalents (168154J63C-F, B32529C0154J000, B32529C0154J289) can be used interchangeably provided PCB layout accommodates the physical dimension variations noted in the parameter comparison table. The B32529C1154J000 (100V upgrade) can be used in any application designed for 63V DC or lower, as it provides higher voltage rating margin.
