Key Parameters

Substitute Part Grouping Explanation

Substitution of the BFC230362394 is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance value: 0.39 µF (exact match required)
• Tolerance: ±5% (matching tolerance band)
• DC voltage rating: 630V (minimum requirement)
• AC voltage rating: 160V (minimum requirement)
• Dielectric type: Polyester, Metallized (material consistency)
• Operating temperature range: -55°C to 105°C (thermal compatibility)
• Mounting configuration: Through-hole radial with PC pins
• Lead spacing: 0.886" (22.50mm) (PCB layout compatibility)

The BFC2373GF394MI qualifies as a direct substitute based on matching all electrical specifications and maintaining compatible mechanical dimensions within acceptable tolerances for through-hole radial mounting.

Parameter Comparison

Engineering Selection Recommendations

The BFC2373GF394MI is the manufacturer-recommended substitute for the obsolete BFC230362394. Both components are manufactured by Vishay and maintain identical electrical specifications across capacitance, voltage ratings, tolerance, and operating temperature range. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

Both parts maintain ROHS3 compliance and MSL Level 1 rating, confirming equivalent environmental and handling characteristics. The mechanical dimensions are compatible for through-hole PCB mounting with identical lead spacing of 0.886" (22.50mm). The substitute exhibits a marginal increase in seated height (18.00mm versus 16.00mm) and width (8.50mm versus 8.10mm), which remains within acceptable tolerances for standard through-hole radial component placement.

Frequently Asked Questions (FAQ)

Q: Can BFC2373GF394MI be used as a direct replacement for BFC230362394 in existing designs?

A: Yes. Both components share identical electrical specifications including capacitance (0.39 µF), voltage ratings (630V DC / 160V AC), tolerance (±5%), dielectric material (polyester metallized), and operating temperature range (-55°C to 105°C). Lead spacing is identical at 0.886" (22.50mm), ensuring PCB compatibility.

Q: What are the physical dimension differences between these parts?

A: The substitute BFC2373GF394MI has a slightly larger footprint. Length remains 1.024" (26.00mm), but width increases from 0.319" to 0.335" (8.10mm to 8.50mm), and seated height increases from 0.630" to 0.709" (16.00mm to 18.00mm). These differences are within acceptable tolerances for radial component placement on standard PCB layouts.

Q: Why is the original BFC230362394 marked as obsolete?

A: The BFC230362394 (MKT303 series) has been discontinued by the manufacturer. The BFC2373GF394MI (MKT373M series) represents the active production equivalent, offering the same electrical performance with improved availability.

Q: Are both parts RoHS compliant?

A: Yes. Both BFC230362394 and BFC2373GF394MI are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating, confirming equivalent environmental qualification.

Q: What applications are these capacitors suitable for?

A: Both components are rated for general-purpose applications requiring 630V DC film capacitor performance with long-life characteristics across the -55°C to 105°C operating range.
