PVC1118 Film Capacitor Equivalent & Substitute Parts

Part Overview

The PVC1118 is a 0.018 µF polyester film capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 100V DC operation with ±10% tolerance. This radial through-hole component is designed for general-purpose applications and operates across a temperature range of -55°C to 125°C.

The PVC1118 carries an Obsolete product status. Locating equivalent substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or repair requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PVC1118 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance value: 0.018 µF (exact match required)
• Tolerance: ±10% (ensures circuit performance specifications)
• Voltage Rating (DC): 100V minimum (electrical safety and reliability)
• Dielectric Material: Polyester (functional equivalence)
• Mounting Type: Through Hole (PCB assembly compatibility)
• Package Type: Radial (physical form factor)
• Termination: PC Pins (solder connection compatibility)

Acceptable Variation Parameters:

• Operating Temperature Range: Substitute may have narrower range if minimum -55°C and maximum ≥105°C are maintained
• Voltage Rating (AC): May differ from original specification
• Physical dimensions: May vary within radial package constraints
• Lead spacing: May differ if through-hole mounting remains compatible

The substitute part BFC237021183 meets all mandatory matching criteria and qualifies as an electrical and mechanical equivalent.

Parameter Comparison

Engineering Selection Recommendations

The BFC237021183 qualifies as an electrical substitute for the PVC1118 based on matching capacitance, tolerance, DC voltage rating, dielectric material, mounting type, package configuration, and termination style. Both components are ROHS3 compliant and REACH unaffected.

Critical Consideration: The substitute part exhibits significantly different physical dimensions and lead spacing. The BFC237021183 measures 7.20mm x 2.50mm with 5.08mm lead spacing, compared to the PVC1118's 8.40mm x 17.80mm dimensions with 12.70mm lead spacing. This dimensional difference requires PCB layout verification before implementation.

The substitute part operates to a maximum temperature of 105°C, compared to the original part's 125°C rating. Applications requiring sustained operation above 105°C must evaluate thermal performance requirements independently.

The BFC237021183 carries Active product status, ensuring ongoing availability and supply chain support, whereas the PVC1118 is Obsolete.

Frequently Asked Questions (FAQ)

Q: Can the BFC237021183 be used as a direct replacement for the PVC1118 without PCB modification?

A: Electrical substitution is valid. However, physical substitution requires PCB layout assessment due to different dimensions (7.20mm x 2.50mm versus 8.40mm x 17.80mm) and lead spacing (5.08mm versus 12.70mm). PCB footprint compatibility must be confirmed before soldering.

Q: What is the significance of the metallized polyester dielectric in the BFC237021183?

A: Both components use polyester dielectric material. The BFC237021183 specifies metallized polyester construction, which is a standard manufacturing variant within the polyester film capacitor category. This does not affect electrical equivalence for the specified capacitance and voltage ratings.

Q: Does the lower maximum operating temperature of the BFC237021183 (105°C versus 125°C) affect substitution suitability?

A: The substitute part's 105°C maximum rating is acceptable for applications operating within this temperature envelope. Applications requiring sustained operation above 105°C must evaluate thermal performance independently and may require alternative components.

Q: Are both parts compliant with environmental and trade regulations?

A: Yes. Both the PVC1118 and BFC237021183 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8532.25.0010.

Q: What is the lead spacing difference between these parts, and why does it matter?

A: The PVC1118 has 12.70mm lead spacing; the BFC237021183 has 5.08mm lead spacing. Lead spacing determines PCB hole pattern compatibility. Substitution requires verification that the PCB footprint accommodates the different spacing, or PCB redesign may be necessary.

Q: Is the BFC237021183 suitable for automotive applications?

A: The BFC237021183 is rated for automotive applications and carries AEC-Q200 qualification. The original PVC1118 is specified for general-purpose applications. If automotive qualification is required, the BFC237021183 provides this additional certification.
