BFC238342272 Film Capacitor Equivalent & Substitute Parts

Part Overview

The BFC238342272 is a 2700 pF metallized polypropylene film capacitor manufactured by Vishay Beyschlag/Draloric/BC Components. This radial through-hole component is rated for 1400V DC and 500V AC operation across a temperature range of -55°C to 105°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Film capacitors of this specification are essential in high-pulse and DV/DT applications where stable capacitance, low ESR, and high voltage handling are required. Equivalent substitutes are identified based on matching capacitance value, tolerance, dielectric material, mounting configuration, and voltage rating compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BFC238342272 is determined by the following critical parameters:

• Capacitance Value: Must be 2700 pF (no tolerance deviation acceptable for direct substitution)
• Tolerance: Must be ±5% or tighter
• Dielectric Material: Polypropylene (PP), Metallized (maintains electrical performance characteristics)
• Mounting Type: Through Hole radial configuration (ensures PCB compatibility)
• Lead Spacing: 0.591" (15.00mm) (required for footprint alignment)
• Voltage Rating - DC: Must equal or exceed 1400V
• Voltage Rating - AC: Must equal or exceed 500V
• Operating Temperature Range: Must encompass or exceed -55°C to 105°C
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

The substitute part B32672L8272J000 meets all substitution criteria with enhanced voltage ratings (2000V DC, 700V AC) and extended temperature range (-55°C to 110°C), providing superior performance margin while maintaining identical capacitance, tolerance, dielectric material, and mechanical footprint.

Parameter Comparison

Engineering Selection Recommendations

The B32672L8272J000 substitute part is electrically and mechanically compatible with the BFC238342272 for direct replacement in through-hole applications. Both parts maintain ROHS3 compliance and active production status. The substitute provides enhanced voltage ratings (2000V DC vs. 1400V DC; 700V AC vs. 500V AC) and extended upper temperature limit (110°C vs. 105°C), offering improved performance margin in high-pulse and DV/DT circuit applications.

Physical dimensions are nearly identical with negligible differences: the substitute is 0.02" longer in length (18.00mm vs. 17.50mm) and 0.02" shorter in seated height (10.50mm vs. 11.00mm). These dimensional variations remain within typical PCB layout tolerances for radial through-hole components with 15.00mm lead spacing. Verification of available PCB clearance is recommended for space-constrained layouts.

Selection between the main part and substitute should be based on circuit voltage requirements, available inventory, and lead time considerations. The substitute part offers superior electrical ratings and is suitable for applications requiring higher voltage margins or extended temperature operation.

Frequently Asked Questions (FAQ)

Q: Can B32672L8272J000 be used as a direct replacement for BFC238342272?

A: Yes. Both parts share identical capacitance (2700 pF), tolerance (±5%), dielectric material (polypropylene metallized), mounting type (through-hole radial), and lead spacing (15.00mm). The substitute has higher voltage ratings and extended temperature range, making it functionally compatible and electrically superior for the same application.

Q: What are the key differences between these two parts?

A: The primary differences are voltage ratings (B32672L8272J000 rated 2000V DC / 700V AC vs. BFC238342272 rated 1400V DC / 500V AC), operating temperature upper limit (110°C vs. 105°C), and minor physical dimensions (length 18.00mm vs. 17.50mm; seated height 10.50mm vs. 11.00mm). Capacitance, tolerance, and dielectric material are identical.

Q: Will the substitute part fit the same PCB footprint?

A: Yes. Both parts have identical lead spacing (15.00mm) and radial through-hole configuration. The dimensional differences (0.02" in length and height) are negligible for standard PCB layouts. Verification of available clearance is recommended only for space-constrained designs.

Q: Are both parts RoHS compliant?

A: Yes. Both BFC238342272 and B32672L8272J000 are ROHS3 compliant and suitable for applications requiring regulatory compliance.

Q: Which part should be selected for new designs?

A: Selection depends on circuit voltage requirements and availability. For applications operating at or below 1400V DC and 500V AC, either part is suitable. For circuits requiring higher voltage margins or extended temperature operation, the B32672L8272J000 substitute is the preferred choice.

Q: What is the moisture sensitivity level (MSL) for the substitute part?

A: The B32672L8272J000 is rated as Not Applicable for MSL, indicating no moisture sensitivity restrictions. The main part BFC238342272 is rated MSL 1 (Unlimited). Both are suitable for standard storage and handling conditions.
