• Identical tolerance: ±10%
• Identical DC voltage rating: 630V
• Identical dielectric material: Polyester, Metallized
• Identical operating temperature range: -55°C ~ 105°C

Mechanical Compatibility:

• Identical mounting type: Through Hole
• Identical package type: Radial
• Identical termination: PC Pins

Regulatory Compliance:

• Both parts maintain ROHS3 compliance
• Both parts have MSL rating of 1 (Unlimited)

The substitute part is from the same manufacturer (Vishay Beyschlag/Draloric/BC Components) and maintains active product status, ensuring continued availability and supply chain reliability.

Parameter Comparison

Engineering Selection Recommendations

The BFC237367683 is the qualified substitute for the obsolete BFC230367683. Both parts maintain identical electrical specifications across capacitance, tolerance, DC voltage rating, dielectric composition, and operating temperature range. Both are ROHS3 compliant with unlimited moisture sensitivity ratings.

The substitute part offers the advantage of active product status, ensuring reliable procurement and supply chain continuity. The BFC237367683 features an elevated AC voltage rating (250V versus 160V), which provides additional design margin in AC applications without affecting DC circuit performance.

Physical dimensions differ between the two parts. The BFC237367683 is larger with increased lead spacing (0.591" versus 0.394"), requiring verification of PCB layout compatibility. Mounting hole spacing and component clearance must be confirmed before implementation in existing designs.

Frequently Asked Questions (FAQ)

Q: Can BFC237367683 be used as a direct replacement for BFC230367683?

A: Electrical substitution is valid. Both parts share identical capacitance (0.068 µF), tolerance (±10%), DC voltage rating (630V), dielectric material (polyester metallized), and operating temperature range (-55°C to 105°C). Physical dimensions differ; PCB layout compatibility must be verified due to increased lead spacing (0.591" versus 0.394") and larger overall package size.

Q: What is the primary reason for substitution?

A: The BFC230367683 is obsolete. The BFC237367683 maintains active product status from the same manufacturer, ensuring continued availability and supply chain reliability.

Q: Are there compliance differences between the parts?

A: Both parts are ROHS3 compliant with MSL rating 1 (Unlimited). No compliance disadvantages exist with the substitute part.

Q: Does the larger physical size of BFC237367683 affect electrical performance?

A: Physical size does not alter electrical characteristics. Capacitance, tolerance, voltage rating, and temperature performance remain identical. Size differences are mechanical considerations relevant only to PCB layout and component placement.

Q: What is the AC voltage rating difference?

A: BFC230367683 is rated 160V AC; BFC237367683 is rated 250V AC. This difference does not affect DC circuit operation. In AC applications, the substitute part provides additional voltage margin.
