PVC1047 Film Capacitor Equivalent & Substitute Parts

Part Overview

The PVC1047 is a 0.47 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) with a 100V DC voltage rating and ±10% tolerance. This component is classified as obsolete, making identification of equivalent substitute parts necessary for ongoing design support and procurement continuity. The radial through-hole configuration and polyester dielectric material define its primary application category as a general-purpose film capacitor suitable for legacy electronic equipment.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PVC1047 are identified based on the following critical parameters that determine functional equivalence:

Electrical Parameters:

• Capacitance value: 0.47 µF (exact match required)
• DC voltage rating: 100V minimum (equal or higher acceptable)
• Tolerance: ±10% (matching tolerance class)
• Dielectric material: Polyester (same material family)

Mechanical Parameters:

• Mounting type: Through Hole (same mounting technology)
• Package configuration: Radial (same lead arrangement)
• Termination: PC Pins (same connection method)

Compliance Parameters:

• RoHS3 compliance (regulatory requirement match)
• Operating temperature range compatibility with application requirements

The BFC237321474 from Vishay Beyschlag/Draloric/BC Components meets these substitution criteria with matching capacitance, voltage rating, tolerance, dielectric material, mounting type, and package configuration.

Parameter Comparison

Engineering Selection Recommendations

The BFC237321474 is a direct functional substitute for the PVC1047 based on matching electrical specifications (0.47 µF, ±10%, 100V DC) and identical mechanical configuration (radial through-hole with PC pin termination). Both components are ROHS3 compliant and suitable for general-purpose applications.

Considerations for substitution:

The BFC237321474 features a metallized polyester dielectric compared to the standard polyester of the PVC1047. This variant offers improved performance characteristics in the active production component. The AC voltage rating of the substitute (63V) is lower than the original (70V), which is not a limiting factor for DC-biased applications but should be evaluated if AC voltage stress is present in the circuit.

The operating temperature range of the substitute extends to 105°C maximum compared to 125°C for the original. Applications requiring operation above 105°C require confirmation that the substitute meets thermal requirements.

The BFC237321474 is currently in active production with 3622 units in stock, providing procurement continuity for the obsolete PVC1047.

Frequently Asked Questions (FAQ)

Q: Can the BFC237321474 be used as a direct replacement for the PVC1047 in all applications?

A: The BFC237321474 matches the critical electrical parameters (capacitance, voltage rating, tolerance) and mechanical configuration (radial through-hole) required for substitution. However, the narrower operating temperature range (-55°C to 105°C versus -55°C to 125°C) must be evaluated for applications requiring sustained operation above 105°C.

Q: What is the difference between standard polyester and metallized polyester dielectric?

A: Both are polyester-based dielectrics. The metallized variant in the BFC237321474 has a thin metal layer deposited on the dielectric surface, which is a standard manufacturing variant that does not affect functional equivalence for general-purpose applications.

Q: Are the physical dimensions compatible for PCB layout?

A: The PVC1047 has dimensions of 0.500" diameter × 1.598" length with 1.343" lead spacing. The BFC237321474 has dimensions of 0.689" length × 0.197" width with 0.591" lead spacing. These are different physical packages. PCB layout compatibility must be verified before substitution, as the lead spacing and overall dimensions differ significantly.

Q: Is the BFC237321474 RoHS compliant?

A: Yes, the BFC237321474 is ROHS3 compliant, matching the compliance status of the PVC1047.

Q: What is the inventory status of the substitute part?

A: The BFC237321474 has 3622 units in stock as new original inventory, providing immediate availability for procurement.
