Key Parameters

Substitute Part Grouping Explanation

The B32672L8392J000 (EPCOS - TDK Electronics) qualifies as a direct substitute for the BFC238501392 based on the following critical parameters:

• Capacitance Match: Both parts are rated at 3900 pF with ±5% tolerance
• Dielectric Material: Both use Polypropylene (PP), Metallized construction
• Operating Temperature: Identical range of -55°C to 110°C
• Mounting Configuration: Both are Through Hole, Radial packages with 0.591" (15.00mm) lead spacing
• Termination Type: Both use PC Pins
• Regulatory Compliance: Both are ROHS3 Compliant

The B32672L8392J000 provides enhanced voltage performance with a DC rating of 2000V (2kV) and AC rating of 700V, compared to the BFC238501392's 1600V DC and 550V AC ratings. This higher voltage rating makes it suitable for applications where the BFC238501392 is specified, provided circuit design accommodates the substitute's superior voltage characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the BFC238501392 and B32672L8392J000 are active production parts with ROHS3 compliance, ensuring regulatory alignment for current and future applications. The BFC238501392 remains the primary specification for designs requiring the exact 1600V DC / 550V AC voltage rating. The B32672L8392J000 serves as a qualified substitute when the primary part is unavailable, provided the circuit design permits operation at the higher 2000V DC / 700V AC voltage rating. Physical dimensions differ slightly (length 17.50mm vs. 18.00mm, height 11.00mm vs. 10.50mm), requiring verification of PCB layout compatibility. Both parts maintain identical lead spacing and termination characteristics, supporting direct socket compatibility in most applications.

Frequently Asked Questions (FAQ)

Q: Can the B32672L8392J000 be used as a direct replacement for the BFC238501392?

A: Yes, the B32672L8392J000 qualifies as a direct substitute based on matching capacitance (3900 pF), tolerance (±5%), dielectric material (Polypropylene metallized), operating temperature range (-55°C to 110°C), mounting type (Through Hole Radial), lead spacing (15.00mm), and termination (PC Pins). The substitute provides higher voltage ratings (2000V DC / 700V AC vs. 1600V DC / 550V AC), which is compatible with applications specified for the primary part.

Q: Are there physical compatibility concerns when substituting the B32672L8392J000 for the BFC238501392?

A: Minor dimensional differences exist. The B32672L8392J000 is 0.02" (0.50mm) longer and 0.02" (0.50mm) shorter in height compared to the BFC238501392. Lead spacing remains identical at 15.00mm. PCB layout should be verified to confirm clearance for the slightly larger length dimension.

Q: What applications are these capacitors suitable for?

A: Both parts are specified for DC Link, DC Filtering, High Frequency Switching, and High Pulse DV/DT applications. The higher voltage rating of the B32672L8392J000 extends its suitability to circuits operating at elevated voltage levels.

Q: Are both parts RoHS compliant?

A: Yes, both the BFC238501392 and B32672L8392J000 are ROHS3 Compliant, meeting current environmental and regulatory requirements.

Q: What is the moisture sensitivity level for these parts?

A: The BFC238501392 has a Moisture Sensitivity Level (MSL) of 1 (Unlimited). The B32672L8392J000 is classified as Not Applicable for MSL, indicating no moisture sensitivity concerns for this component type.
