Key Parameters

Substitute Part Grouping Explanation

Substitution of the BFC246952122 is based on electrical and mechanical parameter matching within the Vishay Beyschlag/Draloric/BC Components product family. The substitute part BFC246756122 maintains identical electrical specifications: 1200 pF capacitance, ±5% tolerance, 400V DC rating, and 220V AC rating. Both components use polyester metallized dielectric construction and operate across the same temperature range (-55°C to 105°C). Mechanical compatibility is preserved through identical lead spacing (0.394" / 10.00mm), radial through-hole mounting configuration, and PC pin termination. The primary difference lies in the series designation (MKT467 versus MKT469) and physical height, with the substitute featuring a maximum seated height of 0.571" (14.50mm) compared to 0.453" (11.50mm) for the original part. Both parts maintain ROHS3 compliance and are suitable for general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

The BFC246756122 is a direct electrical substitute for the obsolete BFC246952122. Both components satisfy identical electrical requirements for 1200 pF capacitance at 400V DC operation with ±5% tolerance. The substitute part is currently in active production status with higher inventory availability (2392 pcs versus 740 pcs), ensuring long-term supply chain continuity. Both parts maintain ROHS3 compliance and are suitable for general-purpose applications across the specified operating temperature range.

The primary consideration for component selection is physical height. The substitute part measures 0.571" (14.50mm) maximum seated height compared to 0.453" (11.50mm) for the original part. This 0.118" (3.00mm) height difference must be evaluated against available PCB clearance in the target application. Lead spacing remains identical at 0.394" (10.00mm), ensuring footprint compatibility on existing circuit board designs.

Frequently Asked Questions (FAQ)

Q: Can BFC246756122 be used as a direct replacement for BFC246952122?

A: Yes, from an electrical standpoint. Both components have identical capacitance (1200 pF), tolerance (±5%), voltage ratings (400V DC / 220V AC), dielectric material (polyester metallized), operating temperature range (-55°C to 105°C), and lead spacing (10.00mm). Physical height differs by 3.00mm, which must be verified against PCB clearance requirements.

Q: What is the primary reason for substitution?

A: The BFC246952122 is classified as obsolete. The BFC246756122 is an active production part from the same manufacturer, providing equivalent electrical performance with assured long-term availability.

Q: Are there any compliance differences between the two parts?

A: No. Both parts are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8532.25.0070) classifications.

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

A: The series designation indicates different product lines within the Vishay Beyschlag/Draloric/BC Components portfolio. Both series employ identical dielectric materials and electrical specifications for this capacitance and voltage rating. The change reflects manufacturing evolution while maintaining electrical equivalence.

Q: How should the height difference be evaluated?

A: Measure available vertical clearance above the component mounting location on the PCB. The substitute part requires an additional 3.00mm of height. If clearance is constrained, physical verification of the PCB layout is necessary before component substitution.

Q: Are packaging considerations different between the two parts?

A: The original part is specified as "-" packaging, while the substitute is supplied in bulk packaging. Both use identical radial through-hole configuration with PC pin termination, ensuring compatibility with standard PCB assembly processes.
