Substitute Part Grouping Explanation

Substitute parts for the 168472K400C-F are classified into two categories based on electrical parameter compatibility:

Direct Equivalents (Same Electrical Specifications) Direct substitutes maintain identical capacitance (4700 pF), tolerance (±10%), voltage rating (400V DC / 200V AC), dielectric material (polyester metallized), and operating temperature range (-55°C to +125°C). These parts differ only in packaging format (Bulk vs. Cut Tape) or minor dimensional variations within acceptable mechanical tolerances. Direct equivalents are:

B32529C6472K000 (Bulk packaging)
B32529C6472K289 (Cut Tape packaging)

Upgrade Substitutes (Enhanced Electrical Specifications) Upgrade substitutes provide improved performance through tighter tolerance or higher voltage rating while maintaining the same 4700 pF capacitance and operating temperature range. These parts are electrically superior and backward-compatible:

B32529C6472J000 and B32529C6472J289: ±5% tolerance (vs. ±10%), same 400V DC rating
B32529C8472J000: ±5% tolerance and 630V DC rating (vs. 400V DC)

All substitute parts are manufactured by EPCOS - TDK Electronics from the B3252* MKT General Purpose series, feature identical lead spacing (5.00 mm), and maintain ROHS3 compliance and REACH unaffected status.

Engineering Selection Recommendations

Direct Equivalent Selection (B32529C6472K000 / B32529C6472K289)

The EPCOS B32529C6472K000 and B32529C6472K289 parts provide direct electrical equivalence to the 168472K400C-F. Both maintain identical capacitance, tolerance, voltage rating, and operating temperature specifications. Selection between these two direct equivalents depends on procurement packaging requirements: B32529C6472K000 is supplied in Bulk packaging, while B32529C6472K289 is supplied in Cut Tape format. Both parts carry AEC-Q200 automotive qualification and ROHS3 compliance. Inventory availability is significantly higher for the Cut Tape variant (12,695 units vs. 1,618 units for Bulk).

Upgrade Substitute Selection (B32529C6472J000 / B32529C6472J289)

The B32529C6472J000 and B32529C6472J289 parts offer tighter ±5% tolerance compared to the original ±10% specification while maintaining identical 400V DC voltage rating and 4700 pF capacitance. These upgrades are electrically backward-compatible and provide improved capacitance accuracy for applications requiring tighter component tolerances. Both parts are AEC-Q200 qualified and ROHS3 compliant. The Bulk variant (B32529C6472J000) has substantially higher inventory (32,171 units).

Premium Upgrade Selection (B32529C8472J000)

The B32529C8472J000 represents the highest performance option, combining ±5% tolerance with 630V DC voltage rating (vs. 400V DC). This part is suitable for applications requiring voltage margin or operating in higher voltage environments. Physical dimensions increase slightly (width 0.138" vs. 0.098", height 0.315" vs. 0.256") due to the higher voltage rating. This part is AEC-Q200 qualified and ROHS3 compliant with 10,004 units in inventory.

All substitute parts maintain identical lead spacing (5.00 mm) for direct PCB footprint compatibility. Minor length variations (0.287" vs. 0.283") are within standard mechanical tolerances and do not affect assembly compatibility.

Frequently Asked Questions (FAQ)

Q: Can B32529C6472K000 or B32529C6472K289 be used as direct replacements for 168472K400C-F?

A: Yes. Both EPCOS parts are direct electrical equivalents with identical 4700 pF capacitance, ±10% tolerance, 400V DC rating, and -55°C to +125°C operating range. The only difference is packaging format (Bulk vs. Cut Tape). Lead spacing is identical at 5.00 mm, ensuring PCB footprint compatibility.

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

A: Tolerance specifies the allowable deviation from the nominal 4700 pF capacitance value. The ±10% tolerance (168472K400C-F, B32529C6472K000, B32529C6472K289) allows capacitance between 4230 pF and 5170 pF. The ±5% tolerance (B32529C6472J000, B32529C6472J289, B32529C8472J000) allows capacitance between 4465 pF and 4935 pF. Tighter tolerance provides improved accuracy for precision applications.

Q: Can B32529C8472J000 be used in place of the original 168472K400C-F?

A: Yes, with physical space considerations. The B32529C8472J000 is electrically superior with ±5% tolerance and 630V DC rating. However, it has larger physical dimensions: width increases from 0.098" to 0.138" and height from 0.256" to 0.315". Verify PCB layout space availability before substitution.

Q: Are all substitute parts automotive-qualified?

A: All EPCOS substitute parts (B3252* series) carry AEC-Q200 automotive qualification. The original CDE 168472K400C-F does not specify automotive qualification. If automotive qualification is required, EPCOS parts are suitable.

Q: What is the inventory status for each substitute part?

A: B32529C6472K289 (Cut Tape) has the highest inventory at 12,695 units. B32529C6472J000 (Bulk, ±5% tolerance) has 32,171 units. B32529C8472J000 (630V upgrade) has 10,004 units. B32529C6472K000 (Bulk, direct equivalent) has 1,618 units. Original 168472K400C-F has 720 units.

Q: Do all parts meet RoHS and REACH compliance?

A: Yes. All parts including the original 168472K400C-F are ROHS3 compliant and REACH unaffected.

Q: What is the significance of "Metallized - Stacked" construction in EPCOS parts?

A: This describes the internal dielectric construction method used by EPCOS. It is functionally equivalent to the polyester metallized construction of the original CDE part for the specified electrical parameters and operating conditions.
