Key Parameters

Substitute Part Grouping Explanation

Substitution of the PVC16247 is determined by the following critical parameters:

Capacitance Value: The substitute must maintain 4700 pF capacitance to ensure circuit functionality.

Voltage Rating: The substitute must meet or exceed the 1600V DC rating of the original part. A higher voltage rating provides design margin and reliability.

Dielectric Material: Polypropylene (PP) dielectric is required to maintain electrical characteristics and frequency response.

Mounting Configuration: Through-hole radial mounting with PC pin termination is mandatory for PCB compatibility.

Operating Temperature Range: The substitute must support the -55°C to 105°C operating window or a superset thereof.

Compliance Standards: RoHS3 compliance and REACH unaffected status are required for regulatory alignment.

The B32672L8472J000 from EPCOS - TDK Electronics satisfies all substitution criteria. This part maintains the 4700 pF capacitance, exceeds the voltage requirement at 2000V DC, utilizes polypropylene dielectric, and operates across -55°C to 110°C, providing extended temperature coverage.

Engineering Selection Recommendations

The B32672L8472J000 is the qualified substitute for the obsolete PVC16247. Selection is based on the following engineering criteria:

Functional Equivalence: Both parts maintain identical 4700 pF capacitance values, ensuring circuit performance is preserved.

Voltage Margin: The B32672L8472J000 provides a 400V DC voltage margin (2000V versus 1600V), enhancing reliability and design robustness in applications subject to voltage transients or aging effects.

Tolerance Improvement: The substitute offers ±5% tolerance compared to the original ±10%, providing tighter capacitance control and improved circuit predictability.

Temperature Coverage: The extended operating range to 110°C accommodates higher ambient conditions while maintaining the lower -55°C threshold.

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and safety requirements.

Product Availability: The B32672L8472J000 is classified as active with 8416 units in stock, ensuring long-term supply continuity compared to the obsolete PVC16247.

Physical Compatibility: Radial through-hole mounting with PC pin termination is identical, permitting direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can the B32672L8472J000 be used as a direct replacement for the PVC16247 in existing designs?

A: Yes. Both components share identical capacitance (4700 pF), mounting type (through-hole radial), termination style (PC pins), and operating temperature lower limit (-55°C). The substitute exceeds the voltage rating and provides improved tolerance, making it functionally compatible for direct substitution.

Q: What is the significance of the higher 2000V DC rating on the B32672L8472J000?

A: The 400V additional voltage margin provides design safety and extends component life in applications experiencing voltage transients, ripple, or aging-related voltage stress. This does not negatively impact circuits designed for 1600V operation.

Q: Does the metallized polypropylene dielectric in the B32672L8472J000 affect circuit performance compared to the standard polypropylene in the PVC16247?

A: Metallized polypropylene maintains the same dielectric properties and frequency response as standard polypropylene. The metallization improves self-healing characteristics and is standard in modern high-reliability film capacitor designs.

Q: Are there any PCB layout modifications required when substituting the B32672L8472J000 for the PVC16247?

A: No layout modifications are required. Both components use identical radial through-hole mounting with PC pin termination. Physical dimensions differ slightly, but lead spacing compatibility (0.969" original versus 0.591" substitute) must be verified for the specific PCB design. If lead spacing differs from the PCB pattern, mechanical adaptation may be necessary.

Q: What is the impact of the ±5% tolerance on the B32672L8472J000 compared to the ±10% tolerance of the PVC16247?

A: The tighter ±5% tolerance reduces capacitance variation across the production batch, improving circuit consistency and predictability. This is advantageous for applications requiring precise frequency response or timing characteristics.

Q: Are both components suitable for high-frequency and switching applications?

A: The PVC16247 is specified for general-purpose applications. The B32672L8472J000 is rated for high-frequency, switching, high-pulse, and DV/DT applications, indicating superior performance in demanding electrical environments. The substitute is suitable for both general-purpose and high-performance applications.

Q: What is the moisture sensitivity level (MSL) difference between these components?

A: The PVC16247 has MSL 1 (unlimited shelf life without moisture control). The B32672L8472J000 has MSL not applicable, indicating no moisture sensitivity concern. Both components are suitable for standard storage and handling without special moisture protection.
