Key Parameters

Substitute Part Grouping Explanation

Substitution of the BFC230344684 is based on the following critical parameters that must remain constant or compatible:

• Capacitance value: 0.68 µF (exact match required)
• Tolerance: ±5% (exact match required)
• DC voltage rating: 250V (minimum requirement)
• Dielectric material: Polyester, Metallized (exact match required)
• Operating temperature range: -55°C to 105°C (minimum requirement)
• Mounting type: Through Hole (exact match required)
• Package type: Radial (exact match required)
• Lead spacing: 0.591" (15.00mm) (exact match required)
• Termination: PC Pins (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The BFC237344684 qualifies as a direct substitute based on these parameters. Physical dimensions may vary within acceptable tolerances for PCB assembly, provided lead spacing and termination type remain unchanged.

Parameter Comparison

Engineering Selection Recommendations

The BFC237344684 is a suitable substitute for the obsolete BFC230344684 based on electrical parameter equivalence. Both parts maintain identical capacitance, tolerance, DC voltage rating, dielectric material, operating temperature range, mounting configuration, and lead spacing. Both are ROHS3 compliant.

The substitute part is from an active product line (MKT373 series), ensuring continued availability and supply chain stability compared to the obsolete MKT303 series. The AC voltage rating of the substitute (160V) exceeds the original specification (63V), providing additional performance margin in AC applications.

Physical dimension differences exist: the substitute is 0.040" (1.00mm) wider and 0.111" (2.80mm) taller. These variations require verification against PCB layout constraints and available mounting space before implementation. Lead spacing remains identical at 0.591" (15.00mm), ensuring compatibility with existing PCB hole patterns.

Frequently Asked Questions (FAQ)

Q: Can BFC237344684 be used as a direct replacement for BFC230344684 in all applications?

A: Electrical substitution is valid based on matching capacitance, tolerance, DC voltage rating, dielectric material, temperature range, and termination specifications. Physical dimensions must be verified against PCB layout constraints due to increased width and height of the substitute part.

Q: What is the significance of the different series designations (MKT303 vs. MKT373)?

A: Series designation indicates different product lines within the manufacturer's portfolio. The MKT373 series is currently active, while MKT303 is obsolete. Both series share compatible electrical and mechanical specifications for this capacitance value.

Q: Does the higher AC voltage rating of the substitute affect circuit performance?

A: The substitute's 160V AC rating exceeds the original 63V AC specification. This provides additional performance margin and does not negatively impact circuit operation when used in applications rated for the original part's AC voltage.

Q: Are there any PCB assembly considerations for the substitute part?

A: The substitute part maintains identical lead spacing (15.00mm), ensuring compatibility with existing PCB hole patterns. However, the increased physical dimensions (width and height) require confirmation that available mounting space accommodates the larger package envelope.

Q: Is RoHS compliance maintained with the substitute part?

A: Both the original and substitute parts are ROHS3 compliant, maintaining regulatory compliance for applications requiring RoHS certification.
