Substitute Part Grouping Explanation

Substitution of the BFC246952103 is determined by strict equivalence across electrical and mechanical parameters. The substitute part BFC246756103 qualifies as a direct equivalent based on the following criteria:

• Identical capacitance value: 1000 pF
• Identical tolerance: ±5%
• Identical voltage ratings: 400V DC / 220V AC
• Identical dielectric material: Polyester, Metallized
• Identical operating temperature range: -55°C to 105°C
• Identical mounting configuration: Through-hole radial
• Identical lead spacing: 0.394" (10.00mm)
• Identical termination type: PC Pins
• Identical RoHS compliance: ROHS3 Compliant

The substitute part belongs to the MKT467 series, representing an active production alternative to the obsolete MKT469 series. Both series maintain identical electrical specifications and mechanical compatibility for PCB integration.

Parameter Comparison

Engineering Selection Recommendations

The BFC246756103 serves as the direct substitute for the obsolete BFC246952103. Both components maintain identical electrical performance specifications and mechanical compatibility. The substitute part is manufactured by the same supplier and carries active production status, ensuring long-term availability and supply chain continuity.

Both parts satisfy ROHS3 compliance requirements. The primary physical difference is the seated height: the substitute part measures 0.555" (14.10mm) compared to 0.437" (11.10mm) for the original part. This dimensional variance must be evaluated against available PCB clearance in the target application to confirm mechanical fit.

Frequently Asked Questions (FAQ)

Q: Can BFC246756103 be used as a direct replacement for BFC246952103?

A: Yes. Both parts share identical electrical specifications: 1000 pF capacitance, ±5% tolerance, 400V DC rating, polyester metallized dielectric, and -55°C to 105°C operating range. Lead spacing and termination type are identical, supporting direct PCB substitution.

Q: What is the primary difference between these two parts?

A: The seated height differs. BFC246952103 measures 0.437" (11.10mm) maximum height, while BFC246756103 measures 0.555" (14.10mm) maximum height. Both maintain identical length and width dimensions of 0.492" x 0.161" (12.50mm x 4.10mm).

Q: Does the height difference affect PCB compatibility?

A: PCB compatibility depends on available vertical clearance in the target application. The 0.118" (3.00mm) height increase must be verified against component placement constraints, solder joint clearance, and any overlying components or enclosure geometry.

Q: Are both parts RoHS compliant?

A: Yes. Both BFC246952103 and BFC246756103 are ROHS3 compliant.

Q: Why is BFC246952103 listed as obsolete?

A: The BFC246952103 belongs to the MKT469 series, which has been discontinued by the manufacturer. The BFC246756103 from the MKT467 series represents the active production equivalent.
