Engineering Selection Recommendations

Direct Equivalent - DME4S22K-F: The DME4S22K-F from Cornell Dubilier Electronics is a direct equivalent with identical electrical specifications (0.022 µF, ±10%, 400V DC, -55°C to 125°C). This part maintains the same lead spacing of 0.295" (7.50mm) and is suitable for direct PCB substitution. The component is smaller in overall dimensions (0.406" L x 0.189" W x 0.370" H) compared to the main part, which may provide space advantages in compact designs. Both parts are active products with ROHS3 compliance.

Primary Substitute - B32520C6223K000: The B32520C6223K000 from EPCOS - TDK Electronics meets all electrical requirements with 0.022 µF capacitance, ±10% tolerance, and 400V DC rating. This part features a stacked metallized polyester dielectric construction and maintains the required 0.295" (7.50mm) lead spacing for PCB compatibility. The component is compact (0.394" L x 0.157" W x 0.335" H) and is actively produced. Inventory availability is substantial at 29534 pieces. This part is suitable for automotive and EMI/RFI suppression applications.

Upgraded Substitute - B32520C6223J000: The B32520C6223J000 offers improved tolerance specification at ±5% compared to the ±10% of the main part, while maintaining all other electrical parameters (0.022 µF, 400V DC, -55°C to 125°C). This EPCOS - TDK Electronics component is appropriate when tighter capacitance tolerance is required by circuit design. Physical dimensions and lead spacing are identical to B32520C6223K000. The part is actively produced with 5426 pieces in inventory.

Legacy Substitute - B32521C6223K: The B32521C6223K from EPCOS - TDK Electronics meets electrical specifications but carries a "Not For New Designs" product status. This part features a different lead spacing of 0.394" (10.00mm) instead of the standard 0.295" (7.50mm), requiring PCB footprint modification. Use of this part is restricted to legacy design support or replacement applications only. The component is not recommended for new circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the DME4S22K-F be used as a direct replacement for the 167223K400C-F?

A: Yes. The DME4S22K-F is a direct equivalent with matching electrical specifications (0.022 µF, ±10%, 400V DC) and identical lead spacing (0.295" / 7.50mm). Both parts are manufactured by Cornell Dubilier Electronics and are active products with ROHS3 compliance. The DME4S22K-F is physically smaller, which may provide layout advantages.

Q: What is the difference between B32520C6223K000 and B32520C6223J000?

A: Both parts are manufactured by EPCOS - TDK Electronics with identical electrical ratings (0.022 µF, 400V DC, -55°C to 125°C) and physical dimensions. The primary difference is tolerance: B32520C6223K000 has ±10% tolerance (matching the original part), while B32520C6223J000 has ±5% tolerance. The tighter tolerance of the J-suffix part makes it suitable for applications requiring higher capacitance accuracy.

Q: Why does B32521C6223K have a different lead spacing?

A: The B32521C6223K features a 0.394" (10.00mm) lead spacing compared to the standard 0.295" (7.50mm) of the main part and other substitutes. This difference reflects a different mechanical design within the EPCOS product line. Use of this part requires PCB footprint modification and is limited to legacy applications due to its "Not For New Designs" status.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (DME4S22K-F, B32520C6223K000, B32520C6223J000, and B32521C6223K) are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: Can I use a substitute part with tighter tolerance in place of the original?

A: Yes. Substitute parts with tighter tolerance specifications (such as B32520C6223J000 with ±5% tolerance) are acceptable replacements for the original ±10% tolerance part. Tighter tolerance does not restrict substitution and may provide improved circuit performance in applications sensitive to capacitance variation.

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

A: Current inventory levels are: DME4S22K-F (2367 pcs), B32520C6223K000 (29534 pcs), B32520C6223J000 (5426 pcs), and B32521C6223K (2429 pcs). The B32520C6223K000 offers the highest availability among EPCOS alternatives.

Q: Are there dimensional constraints I should consider when selecting a substitute?

A: Yes. The main part measures 0.413" L x 0.197" W x 0.433" H. Substitute parts are generally more compact: DME4S22K-F (0.406" x 0.189" x 0.370"), B32520C6223K000 (0.394" x 0.157" x 0.335"), and B32520C6223J000 (0.394" x 0.157" x 0.335"). Smaller dimensions may provide layout advantages but require verification of PCB clearance. The B32521C6223K is larger (0.512" L) and requires footprint modification.

Q: Which substitute is recommended for new designs?

A: For new designs, B32520C6223K000 or B32520C6223J000 are recommended. Both are active EPCOS - TDK Electronics products with excellent inventory availability. B32520C6223J000 is preferred when tighter capacitance tolerance is required. The B32521C6223K should not be used for new designs due to its legacy status.
