Voltage Rating (DC): Minimum 63V
Dielectric Material: Polyester, Metallized
Mounting Type: Through Hole
Package Type: Radial
Termination: PC Pins

Compatible Tolerance Levels:

±10% tolerance (direct equivalent)
±5% tolerance (superior tolerance, acceptable upgrade)

Mechanical Compatibility:

Lead spacing of 0.200" (5.08mm) or 0.197" (5.00mm) are mechanically compatible within PCB design tolerances
Physical dimensions (length and width) within 0.283" to 0.295" L and 0.098" W are compatible
Height seated maximum of 0.256" (6.50mm) is consistent across all candidates

Packaging Formats:

Bulk and Tape & Reel (TR) packaging are functionally equivalent for component selection; packaging choice depends on procurement and assembly requirements

Substitute parts are grouped into two categories: direct equivalents (matching all parameters) and upgrades (enhanced voltage rating or improved tolerance while maintaining all other specifications).

Engineering Selection Recommendations

Direct Equivalent (Recommended Primary Substitute):

BFC237011683 from Vishay Beyschlag/Draloric/BC Components is the direct functional equivalent to BQ014D0683K. This part maintains identical electrical specifications (0.068 µF, ±10%, 63V DC, 40V AC) and mechanical configuration (radial, through-hole, 0.200" lead spacing). The part is in active production status with AEC-Q200 automotive qualification and ROHS3 compliance, ensuring long-term availability and supply chain stability.

Upgrade Alternatives (Enhanced Performance):

Cornell Dubilier Electronics (CDE) offers multiple upgrade options across the 168 and 185 series. These parts provide enhanced specifications while maintaining full backward compatibility:

168683K63A-F and 185683J63RAA-F / 185683J63RAB-F: Match the original 63V DC rating with improved ±5% tolerance and extended operating temperature range (-55°C to 125°C). Available in both bulk and Tape & Reel packaging.

Frequently Asked Questions (FAQ)

Q: Can BFC237011683 be used as a direct replacement for BQ014D0683K?

A: Yes. BFC237011683 matches all critical electrical and mechanical parameters: 0.068 µF capacitance, ±10% tolerance, 63V DC rating, polyester metallized dielectric, radial through-hole configuration, and 0.200" lead spacing. The part is in active production with established supply availability.

Q: What is the difference between the 168 and 185 series CDE parts?

A: Both series are functionally equivalent in electrical performance. The primary difference is packaging: 168 series is supplied in bulk packaging, while 185 series is supplied in Tape & Reel (TR) format. Selection depends on procurement and assembly process requirements.

Q: Are the CDE parts with 0.197" lead spacing compatible with PCBs designed for 0.200" spacing?

A: Yes. The 0.003" (0.076mm) difference in lead spacing is within standard PCB design tolerances and does not affect mechanical fit or electrical performance in through-hole applications.

Q: Can I use a 100V rated part in place of the 63V original?

A: Yes. Parts rated for 100V DC (168683K100H-F, 168683J100H-F, 185683K100RHA-F, 185683J100RHA-F, 185683J100RHB-F) exceed the original voltage requirement and are electrically compatible. Higher voltage rating provides additional safety margin without affecting circuit performance.

Q: What is the advantage of ±5% tolerance over ±10%?

A: ±5% tolerance provides tighter capacitance accuracy, reducing circuit performance variation. Parts with ±5% tolerance (168683J series and 185683J series) are suitable for applications requiring precise capacitance values. ±10% tolerance parts (168683K series and 185683K series) are appropriate for general-purpose applications where the original ±10% specification is acceptable.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All active substitute parts listed (BFC237011683 and all CDE 168/185 series parts) are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: What is the inventory status of these substitute parts?

A: BFC237011683 has 1,527 units in stock. CDE parts range from 685 to 939 units across the 168 series (bulk packaging) and 709 to 912 units across the 185 series (Tape & Reel packaging), ensuring adequate supply for production requirements.
