Engineering Selection Recommendations

Direct PCB Replacement (No Layout Modification Required):

B32521C6223J and B32521N8223J000 are direct mechanical and electrical replacements for the 160223K400C-F. Both parts maintain the 0.394" (10.00mm) lead spacing and identical length dimension (0.512" / 13.00mm). B32521C6223J provides ±5% tolerance upgrade while maintaining 400V rating and Active product status. B32521N8223J000 offers both ±5% tolerance and 630V voltage rating upgrade, providing enhanced design margin. Both EPCOS parts are ROHS3 compliant and suitable for new designs.

Equivalent Specification Match:

B32521C6223K provides identical electrical specifications (0.022 µF, ±10%, 400V) with matching lead spacing. However, this part carries "Not For New Designs" status, limiting its application to legacy system maintenance or repair scenarios only.

Alternative Sourcing with Layout Consideration:

DME4S22K-F (CDE) and B32520C6223K000 (EPCOS) both feature reduced lead spacing (0.295" / 7.50mm) and smaller physical footprints. These parts maintain electrical equivalence but require PCB layout verification before implementation. Both are Active status with extended temperature range (-55°C ~ 125°C).

Compliance and Certification:

All substitute parts maintain ROHS3 compliance and REACH unaffected status. All parts are classified under HTSUS 8532.25.0070 or 8532.25.0010 and ECCN EAR99.

Frequently Asked Questions (FAQ)

Q: Can B32521C6223J replace 160223K400C-F directly on the PCB?

A: Yes. B32521C6223J maintains identical lead spacing (0.394" / 10.00mm), length (0.512" / 13.00mm), and voltage rating (400V DC). The ±5% tolerance is tighter than the original ±10%, providing improved accuracy. No PCB modification is required.

Q: What is the difference between B32521C6223K and B32521C6223J?

A: Both parts are EPCOS B3252* series with identical physical dimensions and lead spacing. The primary difference is tolerance: B32521C6223K has ±10% tolerance (matching the original part), while B32521C6223J has ±5% tolerance. B32521C6223J is Active status; B32521C6223K is Not For New Designs.

Q: Can B32521N8223J000 be used as a drop-in replacement?

A: B32521N8223J000 is mechanically compatible (same lead spacing and length) but has increased width (0.197" vs. 0.157") and height (0.433" vs. 0.374"). PCB layout verification is required to confirm clearance around the component. Electrically, it provides 630V rating and ±5% tolerance, both superior to the original specification.

Q: Why would I choose DME4S22K-F over other substitutes?

A: DME4S22K-F is a CDE product (same manufacturer as the original 160223K400C-F) with identical electrical specifications and extended temperature range (-55°C ~ 125°C). However, its 0.295" lead spacing differs from the original 0.394", requiring PCB layout verification. It offers higher inventory availability (2367 pcs).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the compliance status of the original 160223K400C-F.

Q: What does "Not For New Designs" mean for B32521C6223K?

A: This designation indicates the part is in mature/legacy status and should not be selected for new product development. It remains available for existing designs and repair applications. For new designs, B32521C6223J (Active status) is the recommended EPCOS equivalent.

Q: Can I use a higher voltage rated part (630V) in place of a 400V part?

A: Yes. B32521N8223J000 (630V rating) is electrically compatible with circuits designed for 400V operation. Higher voltage rating provides additional safety margin and does not negatively affect circuit performance. Physical dimensions must still be verified for PCB fit.

Q: What is the lead spacing significance?

A: Lead spacing determines PCB hole pattern compatibility. The original 160223K400C-F uses 0.394" (10.00mm) spacing. Parts with different spacing (0.295" / 7.50mm) require PCB layout verification and may not fit existing through-hole patterns without modification.
