Substitute Part Grouping Explanation

Substitution eligibility for the BFC246955682 is determined by the following critical parameters:

Capacitance value: 6800 pF (exact match required)
Tolerance: ±10% (exact match required)
Dielectric material: Polyester, Metallized (exact match required)
Mounting type: Through Hole (exact match required)
Package type: Radial (exact match required)
Lead spacing: 0.394" (10.00mm) (exact match required)
Termination: PC Pins (exact match required)
Operating temperature range: -55°C to 105°C (exact match required)
Voltage rating (DC): Equal to or greater than 400V
RoHS compliance: ROHS3 Compliant (exact match required)

The identified substitute parts meet all mandatory electrical and mechanical parameters. Voltage rating variations above the minimum 400V specification are acceptable for direct substitution.

Engineering Selection Recommendations

BFC246728682 is the primary substitute option, manufactured by the same supplier (Vishay Beyschlag/Draloric/BC Components) with identical electrical specifications and lead spacing. This part carries active product status and maintains full ROHS3 compliance. Physical dimensions remain consistent with the original design, with the exception of seated height (14.20mm versus 11.20mm), which may require PCB layout verification for clearance constraints.

160682K630C-F represents an alternative from Cornell Dubilier Electronics (CDE) with elevated DC voltage rating (630V versus 400V). This part is active and ROHS3 compliant. Physical dimensions differ slightly in length (13.00mm versus 12.50mm) and seated height (9.50mm versus 11.20mm), requiring confirmation of PCB footprint compatibility before implementation.

Both substitute parts satisfy the mandatory electrical and mechanical substitution criteria. Selection between them depends on supply availability, cost considerations, and physical space constraints within the target application.

Frequently Asked Questions (FAQ)

Q: Can BFC246728682 be used as a direct replacement for BFC246955682?

A: Yes. Both parts share identical capacitance (6800 pF), tolerance (±10%), voltage rating (400V DC), dielectric material (polyester metallized), operating temperature range (-55°C to 105°C), lead spacing (10.00mm), and termination type (PC Pins). The primary difference is seated height (14.20mm versus 11.20mm), which must be verified against PCB layout constraints.

Q: What is the advantage of using 160682K630C-F over BFC246728682?

A: The 160682K630C-F offers higher DC voltage rating (630V versus 400V), providing additional voltage margin in applications where transient overvoltage conditions may occur. This part also features a lower seated height (9.50mm versus 11.20mm), which may be beneficial in space-constrained designs. However, physical dimensions differ slightly, requiring PCB footprint confirmation.

Q: Are all substitute parts RoHS compliant?

A: Yes. BFC246955682, BFC246728682, and 160682K630C-F are all ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: What is the significance of product status (Obsolete vs. Active)?

A: The original BFC246955682 is classified as obsolete, indicating discontinued manufacturing and limited future availability. Both substitute parts carry active status, ensuring continued supply chain access for production and field replacement applications.

Q: Do physical dimension differences affect PCB compatibility?

A: Lead spacing (10.00mm) remains constant across all three parts, ensuring hole pattern compatibility. However, length, width, and seated height variations require verification against PCB layout drawings to confirm clearance for adjacent components and solder joint accessibility.
