Substitute Part Grouping Explanation

Substitution of the BFC237021683 is determined by the following critical parameters:

Capacitance Value: Must be 0.068 µF (exact match required)
Voltage Rating: Minimum 100V DC to maintain circuit safety margins
Tolerance: ±10% or tighter (±5% is acceptable as an upgrade)
Dielectric Material: Polyester metallized construction for equivalent electrical behavior
Mounting Configuration: Through-hole radial package with compatible lead spacing (5.00mm to 5.08mm)
Operating Temperature: Minimum -55°C to 105°C range
Compliance: ROHS3 compliant; AEC-Q200 preferred for automotive applications

Three substitute parts meet these criteria with variations in tolerance grade and manufacturer.

Engineering Selection Recommendations

BFC237022683 (Vishay Beyschlag/Draloric/BC Components): This part is a direct upgrade from the main part, offering tighter ±5% tolerance while maintaining identical voltage rating, temperature range, and AEC-Q200 qualification. Physical dimensions and lead spacing are identical. This substitution is suitable for applications requiring improved capacitance accuracy without design modification.

B32529C1683K189 (EPCOS - TDK Electronics): This part matches the ±10% tolerance of the main part and maintains 100V DC rating. The stacked metallized construction and extended operating temperature range to 125°C provide additional thermal margin. Lead spacing is 5.00mm (versus 5.08mm), requiring verification of PCB hole pattern compatibility. AEC-Q200 rating is not specified for this part.

R82EC2680AA60J (KEMET): This part offers ±5% tolerance with AEC-Q200 qualification and stacked metallized construction. Lead spacing is 5.00mm, requiring PCB compatibility verification. Maximum seated height is 0.260" (6.60mm), which is 0.004" taller than the main part and substitute alternatives. All electrical and compliance specifications are equivalent to the main part.

All substitute parts are ROHS3 compliant and currently in active production status.

Frequently Asked Questions (FAQ)

Q: Can BFC237022683 be used as a direct replacement for BFC237021683?

A: Yes. BFC237022683 is manufactured by the same supplier in the same series with identical physical dimensions, lead spacing, voltage rating, and temperature range. The only difference is improved tolerance (±5% versus ±10%), which is a functional upgrade. No PCB modifications are required.

Q: What is the difference between the Vishay and EPCOS/KEMET substitutes?

A: The Vishay BFC237022683 maintains the original design with standard metallized polyester construction. The EPCOS B32529C1683K189 and KEMET R82EC2680AA60J use stacked metallized construction, which may affect electrical characteristics such as ESR and frequency response. Both EPCOS and KEMET parts have lead spacing of 5.00mm instead of 5.08mm, requiring PCB hole pattern verification.

Q: Are all substitute parts AEC-Q200 qualified?

A: BFC237022683 and R82EC2680AA60J carry AEC-Q200 qualification. B32529C1683K189 does not specify AEC-Q200 rating. For automotive applications requiring AEC-Q200 compliance, BFC237022683 or R82EC2680AA60J are recommended.

Q: What is the impact of lead spacing differences (5.08mm versus 5.00mm)?

A: Lead spacing differences of 0.08mm are within typical PCB manufacturing tolerances for through-hole components. However, PCB hole pattern compatibility must be verified before substitution. If the original design uses 5.08mm spacing, parts with 5.00mm spacing may require PCB redesign or use of component lead bending.

Q: Can B32529C1683K189 be used in high-temperature applications?

A: B32529C1683K189 has an operating temperature range of -55°C to 125°C, which extends 20°C above the main part and other substitutes. This part is suitable for applications requiring operation up to 125°C. However, verify that other circuit components support this temperature range.

Q: Are all parts REACH compliant?

A: Yes. All parts listed are REACH Unaffected, indicating compliance with REACH regulations.
