PVC10247 Film Capacitor Equivalent & Substitute Parts

Part Overview

The PVC10247 is a 4700 pF film capacitor manufactured by Cornell Dubilier Electronics (CDE) with a 1000V DC voltage rating and ±10% tolerance. This component is classified as obsolete, making identification of equivalent substitute parts essential for ongoing system maintenance and new design implementations. The radial through-hole configuration and polyester dielectric material define its primary application profile for general-purpose filtering and coupling circuits.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PVC10247 is determined by strict equivalence in the following electrical and mechanical parameters:

Critical Matching Parameters:

• Capacitance value: 4700 pF (exact match required)
• Voltage rating - DC: 1000V minimum (equal or higher acceptable)
• Mounting type: Through Hole Radial configuration
• Termination style: PC Pins
• RoHS compliance: ROHS3 Compliant

Allowable Variations:

• Tolerance: Substitute may have tighter tolerance (±5% acceptable for ±10% requirement)
• Dielectric material: Alternative film types (polypropylene, polyester) acceptable if electrical ratings maintained
• Operating temperature range: Substitute range may be narrower if minimum -55°C and maximum ≥110°C maintained
• Lead spacing: Physical layout differences acceptable if PCB footprint accommodation possible
• AC voltage rating: May differ from original specification

The B32671L0472J000 meets all critical matching parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The B32671L0472J000 qualifies as a functional substitute for the PVC10247 based on electrical parameter equivalence. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and legacy system replacements.

The substitute component offers improved tolerance specification (±5% versus ±10%), which provides enhanced circuit performance in applications requiring tighter capacitance control. The polypropylene metallized dielectric in the B32671L0472J000 is suitable for high-frequency and switching applications, expanding potential use cases beyond the original polyester design.

Physical layout considerations are necessary due to reduced lead spacing (10.00mm versus 17.50mm). PCB footprint modification or adapter solutions may be required for direct board-level replacement. The narrower operating temperature upper limit (110°C versus 125°C) is acceptable for most general-purpose applications but should be evaluated against specific thermal environment requirements.

Frequently Asked Questions (FAQ)

Q: Can the B32671L0472J000 be used as a direct pin-for-pin replacement?

A: Electrical substitution is valid. Physical substitution requires PCB layout evaluation due to different lead spacing (10.00mm substitute versus 17.50mm original). Mechanical adaptation may be necessary.

Q: What is the significance of the tolerance difference between ±10% and ±5%?

A: The substitute part has tighter tolerance, meaning capacitance values remain closer to the nominal 4700 pF specification. This is advantageous for circuits requiring precise capacitance values and does not create compatibility issues.

Q: Are there dielectric material compatibility concerns?

A: Both polyester (original) and polypropylene metallized (substitute) are standard film capacitor dielectrics. The polypropylene variant offers superior performance in high-frequency and switching applications. Material selection should align with circuit operating conditions.

Q: Does the lower AC voltage rating of the substitute affect compatibility?

A: The substitute is rated 500V AC versus the original 200V AC. Higher AC rating provides additional safety margin and does not create compatibility issues. AC voltage requirements should be confirmed against actual circuit specifications.

Q: What is the impact of the narrower operating temperature range?

A: The substitute operates from -55°C to 110°C versus the original -55°C to 125°C. For applications operating below 110°C, this presents no limitation. Applications requiring sustained operation above 110°C require alternative component selection.

Q: Is the B32671L0472J000 suitable for high-frequency applications?

A: Yes. The substitute is specified for high-frequency and switching applications, making it suitable for circuits beyond the general-purpose classification of the original PVC10247.

Q: Are both components compliant with current regulatory standards?

A: Both components are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for commercial and industrial applications.
