Engineering Selection Recommendations

All listed substitute parts are Active product status with ROHS3 compliance, ensuring regulatory compatibility with the original 168224K50C-F.

For applications requiring no design modification, 168224J50C-F provides direct equivalence with improved tolerance specifications (±5%) while maintaining identical voltage and physical characteristics.

For designs allowing voltage margin, 168224J63C-F and EPCOS B3252* series parts with 63V or 100V DC ratings provide enhanced safety margins. The B3252* series includes AEC-Q200 automotive certification, supporting applications requiring automotive-grade reliability standards.

Physical dimensions vary between CDE 168 series (7.20mm length) and EPCOS B3252* series (7.30mm length), with width reductions in the B3252* 63V variants (2.50mm vs. 3.50mm). These dimensional differences require verification against PCB layout and mounting clearances.

Frequently Asked Questions (FAQ)

Q: Can I substitute 168224J50C-F for 168224K50C-F in existing designs? A: Yes. Both parts maintain identical electrical ratings (0.22 µF, 50V DC) and physical dimensions. 168224J50C-F provides a tighter tolerance specification (±5% vs. ±10%), making it a direct substitute without design modifications.

Q: What is the primary difference between CDE 168 series and EPCOS B3252 series parts?* A: The EPCOS B3252* series offers higher voltage ratings (63V or 100V DC vs. 50V DC), AEC-Q200 automotive certification, and improved component availability. Physical dimensions differ slightly: B3252* parts at 63V are more compact in width (2.50mm vs. 3.50mm).

Q: Are EPCOS B3252 parts suitable for general-purpose applications like the 168224K50C-F?* A: Yes. EPCOS B3252* series is designated as MKT General Purpose, supporting applications including EMI and RFI suppression. Higher voltage ratings provide increased design margin in circuits rated for 50V or lower.

Q: Does physical size change affect PCB layout when using B3252 substitutes?* A: Lead spacing remains constant at 5.00mm, maintaining through-hole mounting compatibility. However, component length and width vary: CDE 168 series at 7.20 x 3.50mm versus B3252* at 7.30 x 2.50mm (63V variants) or 7.30 x 3.50mm (100V variants). PCB layout must accommodate these dimensional variations.

Q: What packaging formats are available for EPCOS B32529C0224J000 and related parts? A: EPCOS B3252* series is supplied in multiple formats: Bulk, Cut Tape (CT), Tape & Box (TB), and Tape & Reel (TR). Part number suffixes indicate packaging: 000 (Bulk), 189 (Tape & Reel), 289 (Cut Tape or Tape & Box). Selection depends on procurement and assembly requirements.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance, matching the regulatory status of the original 168224K50C-F.
