Substitute Part Grouping Explanation

Substitution logic for the 168472K250A-F is based on the following allowed parameters:

Capacitance Requirement: All substitute parts maintain 4700 pF capacitance value.

Voltage Rating: Substitutes are grouped by DC voltage rating. Parts with equal (250V) or higher voltage ratings (400V, 630V) are acceptable substitutes, as higher-rated components operate safely at lower applied voltages.

Tolerance: The original part specifies ±10% tolerance. Substitutes with ±5% tolerance represent improved accuracy and are electrically compatible.

Dielectric & Construction: All substitutes use polyester-based metallized film technology, maintaining the same dielectric class and performance characteristics.

Physical Compatibility: Lead spacing of 0.197" (5.00mm) is maintained across all substitutes for direct PCB footprint compatibility. Height variations occur only with higher voltage ratings (630V variant).

Compliance & Ratings: All substitutes maintain ROHS3 compliance, REACH unaffected status, and AEC-Q200 automotive qualification where applicable.

Engineering Selection Recommendations

Direct Voltage-Rated Substitute (250V DC): B32529C3472J000 provides equivalent voltage performance with improved ±5% tolerance specification. This part is suitable for applications requiring the same 250V DC rating with tighter capacitance accuracy. Both Bulk and standard packaging are available.

Upgraded Voltage Rating (400V DC): B32529C6472J000, B32529C6472J289, B32529C6472K000, and B32529C6472K289 offer 400V DC rating with maintained ±10% tolerance or improved ±5% tolerance. These parts are electrically compatible with 250V applications and provide design margin for higher voltage transients. Packaging options include Bulk and Cut Tape formats.

Maximum Voltage Rating (630V DC): B32529C8472J000 provides the highest voltage rating at 630V DC with ±5% tolerance. Physical dimensions increase (height 0.315" vs. 0.256"), requiring PCB layout verification. This part is suitable for applications requiring maximum voltage headroom and improved tolerance.

Frequently Asked Questions (FAQ)

Q: Can B32529C6472J000 (400V) replace 168472K250A-F (250V) in my circuit?

A: Yes. The 400V rated part operates safely at 250V applied voltage. Higher voltage ratings provide additional design margin and are electrically compatible with lower voltage applications. PCB footprint compatibility is maintained with identical lead spacing of 0.197" (5.00mm).

Q: What is the difference between ±10% and ±5% tolerance substitutes?

A: Both tolerance grades meet the same electrical function. The ±5% tolerance variants (B32529C3472J000, B32529C6472J000, B32529C8472J000) provide tighter capacitance accuracy, beneficial for precision filtering or timing applications. The ±10% variants (B32529C6472K000, B32529C6472K289) match the original part's tolerance specification.

Q: Does the 630V part (B32529C8472J000) fit the same PCB footprint?

A: Lead spacing remains 0.197" (5.00mm), ensuring PCB compatibility. However, the seated height increases from 0.256" to 0.315" (6.50mm to 8.00mm). Verify clearance in the component mounting area before substitution.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements.

Q: What is the difference between Bulk and Cut Tape (CT) packaging?

A: Bulk packaging is standard for manual assembly and lower-volume applications. Cut Tape packaging is formatted for automated pick-and-place assembly equipment. Electrical specifications remain identical; packaging selection depends on assembly process requirements.

Q: Can I use B32529C6472K289 (Cut Tape, 400V, ±10%) as a direct replacement?

A: Yes. This part matches the original tolerance specification (±10%) and maintains identical lead spacing and height. The 400V rating provides voltage margin. Cut Tape packaging is suitable for automated assembly; verify your assembly equipment compatibility.

Q: Which substitute offers the best inventory availability?

A: B32529C6472J000 (400V, ±5%, Bulk) has the highest inventory at 32171 units. B32529C6472K289 (400V, ±10%, Cut Tape) has 12695 units available. Both provide immediate availability for production requirements.
