Key Parameters

Substitute Part Grouping Explanation

Substitution of the BFC246941333 is based on electrical and mechanical parameter equivalence. The primary substitute, BFC246753333, maintains identical electrical specifications: 0.033 µF capacitance, ±10% tolerance, 250V DC / 160V AC voltage ratings, and polyester metallized dielectric composition. Both components share the same through-hole radial mounting configuration with 0.394" (10.00mm) lead spacing and PC pin termination. The key differentiator is physical height: BFC246941333 has a maximum seated height of 0.457" (11.60mm), while BFC246753333 measures 0.575" (14.60mm). This height difference must be evaluated against available PCB clearance in the target application. Both parts maintain ROHS3 compliance and operate across the identical -55°C to 105°C temperature range. The substitute part is currently active in production, providing supply continuity for the obsolete original.

Parameter Comparison

Engineering Selection Recommendations

The BFC246753333 serves as the direct electrical equivalent for the obsolete BFC246941333. Both components satisfy identical electrical requirements: 0.033 µF capacitance at ±10% tolerance with 250V DC / 160V AC voltage ratings. The substitute maintains ROHS3 compliance and operates across the full -55°C to 105°C temperature specification. The active production status of BFC246753333 ensures supply availability and long-term component sourcing stability compared to the obsolete original.

Physical compatibility requires evaluation of the 0.118" (2.97mm) height increase in the substitute part. PCB layout clearance above the component must accommodate the maximum seated height of 0.575" (14.60mm) for BFC246753333. Lead spacing remains constant at 0.394" (10.00mm), ensuring footprint compatibility on existing PCB designs. Both components utilize identical PC pin termination and radial through-hole mounting configuration.

Frequently Asked Questions (FAQ)

Q: Can BFC246753333 replace BFC246941333 in existing designs?

A: Electrical substitution is direct. The capacitance, voltage rating, tolerance, dielectric material, temperature range, and lead spacing are identical. Physical compatibility depends on available vertical clearance on the PCB. The substitute part is 0.118" (2.97mm) taller, requiring confirmation that this height does not interfere with adjacent components or enclosure constraints.

Q: What is the significance of the series designation change from MKT469 to MKT467?

A: The series designation reflects internal Vishay product line organization. Both series employ identical polyester metallized dielectric technology and share the same electrical specifications for this 0.033 µF / 250V rating. The series change does not affect functional equivalence.

Q: Are there any compliance or certification differences between these parts?

A: Both components are ROHS3 compliant. The main part lists MSL as 1 (Unlimited), while the substitute lists MSL as Not Applicable. This difference does not affect component selection for standard through-hole assembly processes.

Q: What inventory status should influence component selection?

A: BFC246753333 is currently active in production with 1098 pieces in stock, providing reliable supply continuity. BFC246941333 is obsolete with 631 pieces remaining in inventory. For new designs and ongoing production, BFC246753333 is the appropriate selection.
