BFC246941273 Equivalent & Substitute Parts

Part Overview

The BFC246941273 is a 0.027 µF film capacitor manufactured by Vishay Beyschlag/Draloric/BC Components, rated for 250V DC operation with polyester metallized dielectric construction. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing design support and procurement continuity. The radial through-hole configuration and general-purpose application profile make this capacitor suitable for replacement with functionally compatible alternatives that maintain electrical and mechanical compatibility within the specified parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BFC246941273 is determined by strict equivalence across the following critical parameters: capacitance value (0.027 µF), tolerance (±10%), dielectric material (polyester metallized), mounting type (through hole radial), lead spacing (0.394"), and termination style (PC pins). Voltage rating compatibility is assessed on a case-by-case basis; substitute parts must meet or exceed the original 250V DC / 160V AC specification to ensure safe operation within the intended circuit environment. Operating temperature range (-55°C to 105°C) and RoHS3 compliance are mandatory for direct substitution. Physical dimensions, while not identical across all candidates, must accommodate the original PCB footprint constraints.

Parameter Comparison

Engineering Selection Recommendations

BFC246753273 is the primary equivalent substitute for BFC246941273. Both components are manufactured by Vishay and share identical electrical specifications (0.027 µF, ±10%, 250V DC, 160V AC, polyester metallized dielectric). The BFC246753273 maintains active product status and ROHS3 compliance. The primary design consideration is the increased seated height (0.559" versus 0.441"), which must be verified against PCB clearance constraints and component placement density requirements.

160273K400C-F, manufactured by Cornell Dubilier Electronics, provides an alternative with elevated voltage ratings (400V DC, 200V AC). This part is suitable for applications requiring higher voltage margin or operating in elevated voltage environments. The reduced seated height (0.374") may offer PCB layout advantages. Dimensional variations in length and width (13.00mm x 4.00mm versus 12.50mm x 4.20mm) require footprint verification. Both substitute parts maintain ROHS3 compliance and the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can BFC246753273 directly replace BFC246941273 on existing PCBs? A: Electrical substitution is direct; both parts share identical capacitance, tolerance, voltage rating, and dielectric specifications. Physical substitution requires verification of the increased seated height (14.20mm versus 11.20mm) against available PCB clearance.

Q: Is 160273K400C-F suitable for the original BFC246941273 application? A: Yes, provided the circuit design accommodates the higher voltage ratings (400V DC, 200V AC). The elevated voltage specification provides additional safety margin. Dimensional differences must be evaluated for PCB compatibility.

Q: What are the key differences between the two substitute parts? A: BFC246753273 matches the original voltage specification exactly (250V DC, 160V AC) but has greater seated height. 160273K400C-F offers higher voltage ratings with reduced seated height but comes from a different manufacturer (Cornell Dubilier versus Vishay).

Q: Are all three parts RoHS3 compliant? A: Yes. BFC246941273, BFC246753273, and 160273K400C-F are all ROHS3 compliant, meeting environmental and regulatory requirements for current procurement standards.

Q: Does lead spacing differ among these parts? A: No. All three parts maintain 0.394" (10.00mm) lead spacing, ensuring PCB footprint compatibility at the pin level.

Q: What is the impact of the height difference on component placement? A: BFC246753273 has maximum seated height of 14.20mm (versus 11.20mm original), requiring clearance verification. 160273K400C-F has reduced height of 9.50mm, potentially offering layout advantages in space-constrained designs.
