Key Parameters

Substitute Part Grouping Explanation

Substitution of the BFC230353125 is determined by strict equivalence across the following critical parameters:

• Capacitance value: 1.2 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating - DC: 400V (minimum acceptable rating)
• Dielectric Material: Polyester, Metallized (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Lead Spacing: 0.886" (22.50mm) (exact match required for PCB compatibility)
• Termination: PC Pins (exact match required)

The BFC237353125 meets all substitution criteria. Both parts share identical capacitance, tolerance, DC voltage rating, dielectric composition, mounting configuration, lead spacing, and termination type. The substitute part is from the same manufacturer family (MKT series) and maintains full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The BFC237353125 is the direct substitute for the obsolete BFC230353125. Both components are ROHS3 compliant and maintain identical MSL ratings. The substitute part is currently in active production status with higher inventory availability (2928 pcs vs. 896 pcs), ensuring long-term supply chain continuity.

Physical dimensions show minor increases in width (0.394" vs. 0.331") and seated height (0.768" vs. 0.642"), which must be verified against PCB layout constraints. Lead spacing remains identical at 0.886" (22.50mm), ensuring direct PCB footprint compatibility.

The AC voltage rating difference (220V vs. 100V) does not affect DC-rated applications. Both parts are rated for 400V DC operation and share identical temperature operating range, capacitance, tolerance, and dielectric properties.

Frequently Asked Questions (FAQ)

Q: Can BFC237353125 be used as a direct replacement for BFC230353125?

A: Yes. Both parts meet identical electrical specifications for capacitance (1.2 µF), tolerance (±10%), DC voltage rating (400V), dielectric material (polyester metallized), and lead spacing (22.50mm). Physical dimensions differ slightly; verify PCB clearance for the increased height and width of the substitute part.

Q: What is the primary reason for substitution?

A: The BFC230353125 is obsolete. The BFC237353125 is an active production part from the same manufacturer with equivalent electrical and mechanical properties.

Q: Are there compliance differences between the two parts?

A: No. Both parts are ROHS3 compliant with MSL rating of 1 (Unlimited). Moisture sensitivity and environmental compliance are identical.

Q: Does the higher AC voltage rating of BFC237353125 affect DC applications?

A: No. AC voltage rating does not apply to DC-only circuits. Both parts are rated for 400V DC operation, which is the controlling specification for this application category.

Q: What physical constraints must be considered during substitution?

A: The BFC237353125 is 0.063" (1.6mm) wider and 0.126" (3.2mm) taller than the original part. Verify that PCB layout, component spacing, and enclosure clearances accommodate these dimensional increases. Lead spacing remains unchanged at 22.50mm.
